Plain git compresses these well and avoids LFS bandwidth entirely. Defer until next maintenance pass. + +### luxfi/state and luxfi/explore — recommend cleanup of stale declarations + +- Remove the unused `filter=lfs` lines from each repo's `.gitattributes` to prevent future accidental commits flowing into LFS. +- One-line PR per repo. No object migration required (no objects exist). + +### Quota increase + +Not recommended. Bandwidth burn is concentrated in one fixable repo; throwing quota at it postpones the real fix. + +## Out of Scope (separate dispatches) + +- Per-repo migrations (snapshots → release-assets, attribute cleanups). +- Server-side LFS pruning / `git filter-repo` rewrite of `luxfi/snapshots` history. +- Cross-org survey (hanzoai, zooai) — separate audit. diff --git a/LICENSE b/LICENSE deleted file mode 100644 index 6417c152..00000000 --- a/LICENSE +++ /dev/null @@ -1,65 +0,0 @@ -BSD 3-Clause License - Network Restricted - -Copyright (c) 2025 Lux Industries Inc. -All rights reserved. - -Redistribution and use in source and binary forms, with or without -modification, are permitted provided that the following conditions are met: - -1.

A security token on Lux is a regulated ERC-20 with embedded compliance enforcement at the transfer layer. The on-chain token contract IS the cap table. The on-chain compliance registry IS the KYC/AML gate. Every transfer, every dividend payment, every corporate action is a verifiable on-chain transaction with an immutable audit trail. + +Lux operates the full regulated stack: Alternative Trading System (ATS), Broker-Dealer (BD), and Transfer Agent (TA). The on-chain contracts are the execution layer for all three. + +## Motivation + +Traditional securities infrastructure relies on: +- Paper cap tables maintained by transfer agents (Computershare, AST) +- Settlement via DTCC with T+1 (formerly T+2) delays +- Reconciliation across multiple intermediaries who each maintain separate ledgers +- Restricted secondary trading through closed systems with limited interoperability + +Digital securities on Lux collapse the entire stack into on-chain primitives: +- `SecurityToken.balanceOf()` replaces the shareholder registry +- `ComplianceRegistry.canTransfer()` replaces manual compliance checks +- `DividendDistributor.claim()` replaces paper dividend warrants +- Settlement is atomic and final within 1ms (Lux consensus finality) + +The result: 24/7 trading, instant settlement, automated compliance, and a single source of truth. + +## Standards Compatibility + +### ERC-1404: Simple Restricted Token + +The base standard. Every SecurityToken implements ERC-1404, which adds two functions to ERC-20: + +```solidity +function detectTransferRestriction(address from, address to, uint256 value) + external view returns (uint8 restrictionCode); + +function messageForTransferRestriction(uint8 restrictionCode) + external view returns (string memory message); +``` + +Callers check restrictions before submitting a transfer. Wallets and DEXs use this to display human-readable rejection reasons. + +### ERC-3643 (T-REX): Institutional Compliance + +ERC-3643 defines the Token for Regulated EXchanges framework.

Compliance bypass on mint/burn: By design, minting and burning bypass compliance. This is intentional -- the issuer must be able to issue and redeem. The MINTER_ROLE controls who can do this. +4.

The same DEX binary operates in two modes: unregulated (permissionless, any ERC-20) and regulated (compliance-enforced, security tokens). The difference is configuration -- whether a pool has a ComplianceHook attached. + +## Motivation + +Security tokens cannot trade on permissionless DEXs. Every swap involving a security token is a transfer that must pass compliance checks (KYC, accreditation, jurisdiction, lockup). Without enforcement at the DEX layer, an investor could bypass compliance by swapping through a pool instead of calling `transfer()` directly. + +The Uniswap V4 hooks architecture solves this cleanly. A hook contract executes before and/or after each swap, providing a natural enforcement point. Lux implements this as a native precompile hook, not a Solidity contract, for gas efficiency and tamper resistance. + +## Design Principles + +1. **Same binary, different config.** The DEX precompile is one piece of software. A pool with no hook is permissionless. A pool with `ComplianceHook` is regulated. No code fork. +2. **Compliance at the pool level.** Each pool independently decides its compliance posture. A USDC/ETH pool is permissionless. An ACME-SHARES/USDC pool has `ComplianceHook`. +3. **No new compliance logic.** `ComplianceHook` delegates entirely to `ComplianceRegistry`. The same compliance rules that govern direct `transfer()` govern DEX swaps. +4. **Fail closed.** If the compliance check reverts or returns false, the swap reverts. There is no fallback, no degraded mode. + +## Hook Architecture + +### V4 Hook Lifecycle + +The Lux DEX precompile (LP-9010) implements the Uniswap V4 PoolManager pattern with the following hook points: + +``` +beforeInitialize -> afterInitialize +beforeAddLiquidity -> afterAddLiquidity +beforeRemoveLiquidity -> afterRemoveLiquidity +beforeSwap -> afterSwap +beforeDonate -> afterDonate +``` + +`ComplianceHook` uses: +- `beforeSwap` -- validate that both counterparties pass compliance before the swap executes +- `afterSwap` -- post-trade reporting (emit events for off-chain surveillance) +- `beforeAddLiquidity` -- validate LP provider is whitelisted (for regulated pools) +- `beforeRemoveLiquidity` -- validate LP provider is still in good standing + +### ComplianceHook Interface + +```solidity +// SPDX-License-Identifier: MIT +pragma solidity ^0.8.24; + +import {IHooks} from "@luxfi/dex/interfaces/IHooks.sol"; +import {PoolKey} from "@luxfi/dex/types/PoolKey.sol"; +import {BalanceDelta} from "@luxfi/dex/types/BalanceDelta.sol"; +import {BeforeSwapDelta} from "@luxfi/dex/types/BeforeSwapDelta.sol"; +import {ComplianceRegistry} from "@luxfi/standard/securities/compliance/ComplianceRegistry.sol"; + +contract ComplianceHook is IHooks { + ComplianceRegistry public immutable REGISTRY; + + error SwapRestricted(address account, uint8 restrictionCode); + error LiquidityRestricted(address account, uint8 restrictionCode); + + constructor(ComplianceRegistry _registry) { + REGISTRY = _registry; + } + + function beforeSwap( + address sender, + PoolKey calldata key, + IPoolManager.SwapParams calldata params, + bytes calldata hookData + ) external returns (bytes4, BeforeSwapDelta, uint24) { + // Decode the actual trader (sender may be a router) + address trader = hookData.length >= 20 + ? abi.decode(hookData, (address)) + : sender; + + // Check compliance for the trader + (bool allowed, uint8 code) = REGISTRY.canTransfer( + trader, // from + trader, // to (self, for swap eligibility) + 0 // amount not relevant for eligibility + ); + if (!allowed) revert SwapRestricted(trader, code); + + return (IHooks.beforeSwap.selector, BeforeSwapDelta(0, 0), 0); + } + + function afterSwap( + address sender, + PoolKey calldata key, + IPoolManager.SwapParams calldata params, + BalanceDelta delta, + bytes calldata hookData + ) external returns (bytes4, int128) { + // Post-trade event for surveillance + // (implementation emits TradeExecuted event) + return (IHooks.afterSwap.selector, 0); + } + + function beforeAddLiquidity( + address sender, + PoolKey calldata key, + IPoolManager.ModifyLiquidityParams calldata params, + bytes calldata hookData + ) external returns (bytes4) { + address provider = hookData.length >= 20 + ? abi.decode(hookData, (address)) + : sender; + + (bool allowed, uint8 code) = REGISTRY.canTransfer(provider, provider, 0); + if (!allowed) revert LiquidityRestricted(provider, code); + + return (IHooks.beforeAddLiquidity.selector); + } +} +``` + +### Address Prefix Pattern + +Uniswap V4 uses the hook contract address to determine which hook functions are active. The leading bytes of the address encode permissions as flags. + +For compliance hooks, the canonical address prefix is: + +``` +0x07D4............................................ +``` + +The `0x07D4` prefix encodes the following permission flags: + +| Bit | Permission | Enabled | +|-----|-----------|---------| +| 0 | beforeInitialize | No | +| 1 | afterInitialize | No | +| 2 | beforeAddLiquidity | Yes | +| 3 | afterAddLiquidity | No | +| 4 | beforeRemoveLiquidity | Yes | +| 5 | afterRemoveLiquidity | No | +| 6 | beforeSwap | Yes | +| 7 | afterSwap | Yes | +| 8 | beforeDonate | No | +| 9 | afterDonate | No | + +`0x07D4` = `0000 0111 1101 0100` -- enabling beforeAddLiquidity, beforeRemoveLiquidity, beforeSwap, and afterSwap. + +Hook deployment uses `CREATE2` with a salt mined to produce an address starting with `0x07D4`. The mining process: + +```solidity +bytes32 salt = keccak256(abi.encodePacked(deployer, nonce)); +address hook = CREATE2(salt, type(ComplianceHook).creationCode, abi.encode(registry)); +require(uint160(hook) >> 148 == 0x07D4); // verify prefix +``` + +### Pool Configuration + +When creating a regulated pool: + +```solidity +PoolKey memory key = PoolKey({ + currency0: Currency.wrap(address(securityToken)), + currency1: Currency.wrap(address(usdc)), + fee: 3000, // 0.3% fee tier + tickSpacing: 60, + hooks: IHooks(complianceHook) // compliance hook address (0x07D4...) +}); + +poolManager.initialize(key, sqrtPriceX96); +``` + +When creating an unregulated pool, simply omit the hook or use a different hook: + +```solidity +PoolKey memory key = PoolKey({ + currency0: Currency.wrap(address(tokenA)), + currency1: Currency.wrap(address(tokenB)), + fee: 3000, + tickSpacing: 60, + hooks: IHooks(address(0)) // no hook -- permissionless +}); +``` + +## Regulated vs Unregulated DEX + +### Same Binary, Different Config + +The Lux DEX precompile (LP-9010) does not distinguish between "regulated mode" and "unregulated mode" at the protocol level. The distinction is per-pool: + +| Pool Type | Hook | Behavior | +|---|---|---| +| Permissionless | `address(0)` or utility hook | Any address can trade | +| Regulated | `ComplianceHook` at `0x07D4...` | Only whitelisted addresses can trade | +| Mixed fee | `DynamicFeeHook` | Custom fee logic | + +This means a single DEX deployment serves both regulated and unregulated markets. No separate infrastructure. No separate liquidity. + +### What This Enables + +1. **Institutional DeFi**: Security tokens trading on a DEX with full compliance enforcement +2. **Hybrid pools**: A regulated security token paired with a permissionless stablecoin +3. **Compliance-as-a-service**: Third-party compliance providers deploy their own hooks +4. **Regulatory clarity**: Regulators can verify compliance enforcement by inspecting the hook address + +### What This Prevents + +1. **Compliance bypass**: An investor cannot buy a security token on a permissionless pool because the token's `_update()` hook (in `SecurityToken`) also enforces compliance. Even if somehow a pool existed without a ComplianceHook, the underlying token transfer would revert. +2. **Unauthorized market making**: Only whitelisted addresses can add liquidity to regulated pools. + +## Trade Surveillance + +`ComplianceHook.afterSwap` emits events consumed by the off-chain surveillance system: + +```solidity +event RegulatedSwap( + address indexed trader, + address indexed token0, + address indexed token1, + int256 amount0, + int256 amount1, + uint160 sqrtPriceX96, + uint128 liquidity, + int24 tick, + uint256 timestamp +); +``` + +The surveillance system (`lux/cex` monitoring module) indexes these events for: +- Wash trading detection +- Insider trading pattern analysis +- Market manipulation alerts +- FINRA trade reporting (TRACE for fixed income, ORF for OTC equity) + +## Gas Considerations + +The ComplianceHook adds a `ComplianceRegistry.canTransfer()` call to every swap. This is a `view` call that reads: +- 2 storage slots (whitelist sender, whitelist receiver) +- 2 storage slots (blacklist sender, blacklist receiver) +- 1 storage slot (lockup sender) +- N module calls (typically 0-3 modules, each 1-3 storage reads) + +Estimated additional gas per swap: ~8,000-15,000 gas depending on module count. This is acceptable for regulated markets where compliance cost is already priced in. + +On the native DEX precompile (LP-9010), compliance checks execute as precompile-to-precompile calls, reducing overhead to ~3,000-5,000 gas. + +## Deployment + +1. Deploy `ComplianceRegistry` (if not already deployed for this token) +2. Mine a `CREATE2` salt producing an address with `0x07D4` prefix +3. Deploy `ComplianceHook` with the registry address using the mined salt +4. Create the regulated pool with the hook address +5. Add initial liquidity (liquidity provider must be whitelisted) + +## Security Considerations + +1. **Hook immutability**: Once a pool is initialized with a hook, the hook cannot be changed. This prevents compliance removal after pool creation. +2. **Registry upgrades**: The hook points to an immutable registry address. To upgrade compliance rules, deploy new modules and add them to the existing registry. Do not redeploy the registry. +3. **Router trust**: The `hookData` parameter is used to pass the actual trader address when a swap goes through a router.

The nonce includes `block.timestamp` and `block.number`, making it unique per-block. Two locks in the same block from the same sender for the same amount produce different nonces due to different call positions. + +2. **Warp signature verification**: The destination chain verifies the BLS aggregate signature against the source subnet's registered validator set on the P-Chain. A compromised minority of validators cannot produce a valid Warp message (67% threshold minimum). + +3. **MPC key compromise**: If the MPC signing threshold is compromised, the attacker can mint tokens on destination chains. Mitigation: per-asset key groups, HSM backing, quarterly rotation, real-time monitoring of bridge events. + +4. **Compliance desynchronization**: If chain A whitelists a user and chain B has not synced yet, the user can lock on A but cannot trade on B. This is a liveness issue, not a safety issue -- compliance sync latency is the bottleneck. The compliance service targets < 30 second sync across chains. + +5. **Double-spend via reorg**: If the source chain reorgs after a lock is processed, the destination chain has already minted. Mitigation: wait for finality before processing (Lux finality is 1ms, so reorgs are practically impossible under normal conditions). + +6. **Token supply audit**: The bridge invariant (locked + remote supply = home supply) must be auditable. Both the home chain bridge balance and remote chain total supply are public on-chain state. An automated monitor verifies the invariant every block. + +## Reference + +| Resource | Location | +|---|---| +| SecurityBridge contract | `github.com/luxfi/standard/contracts/securities/bridge/SecurityBridge.sol` | +| Warp Messaging 2.0 | `lp-6022-warp-messaging-20-native-interchain-transfers.md` | +| T-Chain MPC Custody | `lp-5013-t-chain-decentralised-mpc-custody-and-swap-signature-layer.md` | +| Teleport Bridge Architecture | `lp-6332-teleport-bridge-architecture-unified-cross-chain-protocol.md` | +| LP-001 Digital Securities | `LP-001-digital-securities.md` | +| tZero API | https://tzero.com | + +## Copyright + +Copyright (c) 2026 Lux Partners Limited.

It is the +serializability fabric beneath Prism frontiers, EVM fibers, DEX +precompiles, and Quasar-certified roots. + +The headline change: Block-STM stops being a *retroactive* conflict +detector and becomes a *scheduler-aware* fabric that continuously feeds +contention telemetry back into Prism partitioning.

TicToc cannot reorder +Nova/Nebula commit order — it only proves that an observed version is +still serializable under the canonical order. + +### From TL2 (DISC 2006, Dice/Shalev/Shavit) +**Borrow**: commit-time locking + version-clock validation. **Adapt**: +no single global TL2 clock. **Lane clocks** replace it.

This admits more commits than strict "anything +changed means abort" while preserving deterministic output. + +**Hard rule**: TicToc timestamps cannot reorder consensus. They only +prove that an observed version is still serializable under the +canonical order. + +## Prism Refraction + +For Nebula, the frontier is a ready antichain — but *ready ≠ +conflict-free*.

Each chain deployment is sovereign: it has its own governor, fee configuration, and signer group. The router verifies aggregate MPC group threshold signatures (not individual signers), enforces a 7-day timelock on signer rotation, auto-pauses on undercollateralization, and guarantees that burns (exits) always succeed regardless of contract state. + +## Motivation + +Existing bridge routers share a single governance surface across all chains. A governance compromise on one chain cascades to all chains. Bridge users have no exit guarantee when governance is captured or when the contract is paused. + +OmnichainRouter addresses this by: +1. Isolating governance per chain deployment -- a compromised governor on chain A cannot affect chain B +2. Verifying MPC group threshold keys rather than individual signer addresses, eliminating the N-of-M signer enumeration attack surface +3. Enforcing a 7-day timelock on signer rotation so users can exit before a malicious key rotation takes effect +4. Guaranteeing that `burn()` (exit) always executes, even when the contract is paused +5. Auto-pausing mints when collateral drops below the minted supply + +## Specification + +### 1. Chain Registry + +The router supports 270 chain IDs. Each chain is registered with its bridge parameters: + +```solidity +struct ChainConfig { + uint256 chainId; + bool active; + uint256 minBridgeAmount; + uint256 maxBridgeAmount; + uint256 dailyLimit; + uint256 dailyVolume; + uint256 lastResetTimestamp; +} + +mapping(uint256 => ChainConfig) public chains; // chainId => config +uint256 public chainCount; // current: 270 +``` + +The governor can activate/deactivate chains and adjust per-chain limits. Adding a new chain increments `chainCount`. + +### 2. MPC Group Verification + +The router does NOT store individual signer addresses. It stores a single aggregate public key representing the MPC group: + +```solidity +bytes32 public signerGroupKey; // keccak256 of the aggregate public key +uint256 public signerGroupKeyEffective; // timestamp when current key became active +``` + +Signature verification: + +```solidity +function _verifySignature(bytes32 messageHash, bytes calldata signature) internal view { + // Recover aggregate public key from signature + // Verify it matches signerGroupKey + // Single ecrecover for ECDSA groups (CGGMP21) + // Precompile 0x000C for FROST groups (EdDSA) +} +``` + +This design means the contract never knows how many signers exist or what the threshold is. That is internal to the MPC group. The contract only verifies the final aggregate signature. + +### 3. Timelock Signer Rotation + +Signer rotation is subject to a mandatory 7-day timelock: + +```solidity +uint256 public constant ROTATION_DELAY = 7 days; + +bytes32 public pendingSignerGroupKey; +uint256 public rotationUnlocksAt; + +function proposeSignerRotation(bytes32 newKey) external onlyGovernor { + pendingSignerGroupKey = newKey; + rotationUnlocksAt = block.timestamp + ROTATION_DELAY; + emit SignerRotationProposed(newKey, rotationUnlocksAt); +} + +function executeSignerRotation() external { + require(block.timestamp >= rotationUnlocksAt, "timelock active"); + require(pendingSignerGroupKey != bytes32(0), "no pending rotation"); + + signerGroupKey = pendingSignerGroupKey; + signerGroupKeyEffective = block.timestamp; + pendingSignerGroupKey = bytes32(0); + rotationUnlocksAt = 0; + + emit SignerRotated(signerGroupKey); +} + +function cancelSignerRotation() external onlyGovernor { + pendingSignerGroupKey = bytes32(0); + rotationUnlocksAt = 0; + emit SignerRotationCancelled(); +} +``` + +The 7-day window gives users time to exit (burn) if they disagree with the proposed new signer group. + +### 4. Exit Guarantee + +Burns (exits from bridged tokens back to the home chain) are ALWAYS allowed, regardless of pause state: + +```solidity +bool public paused; + +modifier whenNotPaused() { + require(!paused, "paused"); + _; +} + +function lock(uint256 amount, uint256 destChainId) external whenNotPaused { ... } +function bridgeMint(address to, uint256 amount, bytes calldata sig) external whenNotPaused { ... } + +// Burns are NEVER gated by pause +function burn(uint256 amount, uint256 destChainId) external { + // No pause check -- exit always allowed + TOKEN.burnFrom(msg.sender, amount); + emit Burned(msg.sender, amount, destChainId); +} +``` + +This is a hard guarantee: no governance action, no pause, no signer rotation can prevent a user from burning their bridged tokens to initiate an exit back to the home chain. + +### 5. Auto-Pause on Undercollateralization + +The router monitors the collateral invariant: + +``` +locked_on_home_chain >= total_minted_on_remote_chains +``` + +If a mint would violate this invariant, the router auto-pauses: + +```solidity +uint256 public totalMinted; +uint256 public totalLocked; + +function bridgeMint(address to, uint256 amount, bytes calldata sig) external whenNotPaused { + _verifySignature(keccak256(abi.encode(to, amount, block.chainid)), sig); + + if (totalMinted + amount > totalLocked) { + paused = true; + emit AutoPaused(totalLocked, totalMinted + amount); + revert("undercollateralized"); + } + + totalMinted += amount; + TOKEN.mint(to, amount); + emit Minted(to, amount); +} +``` + +Auto-pause can only be lifted by the governor after the collateral invariant is restored. + +### 6. Fee Structure + +Fees are split between a staking vault and the treasury: + +```solidity +uint256 public bridgeFeeBps; // total fee in basis points (e.g. 30 = 0.30%) +uint256 public stakeholderShareBps; // share to staking vault (e.g. 7000 = 70%) +address public stakingVault; +address public treasury; + +function _collectFee(uint256 amount) internal returns (uint256 netAmount) { + uint256 fee = (amount * bridgeFeeBps) / 10_000; + uint256 stakingShare = (fee * stakeholderShareBps) / 10_000; + uint256 treasuryShare = fee - stakingShare; + + TOKEN.safeTransfer(stakingVault, stakingShare); + TOKEN.safeTransfer(treasury, treasuryShare); + + return amount - fee; +} +``` + +The governor can adjust `bridgeFeeBps` and `stakeholderShareBps`. The governor CANNOT call `mint()` directly -- minting is only possible through the verified MPC signature path in `bridgeMint()`. + +### 7. Governor Permissions + +```solidity +// Governor CAN: +function setFees(uint256 newFeeBps, uint256 newShareBps) external onlyGovernor; +function setChainConfig(uint256 chainId, ChainConfig calldata config) external onlyGovernor; +function proposeSignerRotation(bytes32 newKey) external onlyGovernor; +function cancelSignerRotation() external onlyGovernor; +function unpause() external onlyGovernor; + +// Governor CANNOT: +// - mint tokens (only bridgeMint with valid MPC signature) +// - prevent burns (exit guarantee) +// - bypass timelock on signer rotation +// - override auto-pause without restoring collateral +``` + +### 8. Supported Chains + +The router is deployed on 270 chains at launch. Chain registry includes all EVM-compatible chains, Lux subnets, and chains reachable via the Teleport protocol (LP-017 native programs). The full chain ID list is maintained in the deployment manifest and is not hardcoded in the contract. + +## Security Considerations + +1. **MPC group opacity**: The contract cannot distinguish between a 3-of-5 and a 5-of-5 threshold. This is by design -- threshold policy is enforced off-chain by the MPC protocol (LP-019). On-chain verification only confirms the aggregate signature is valid. + +2. **Timelock window**: 7 days is chosen to exceed the typical DeFi governance attack window (2-3 days). Users monitoring the `SignerRotationProposed` event have sufficient time to burn and exit. + +3. **Exit guarantee under pause**: A paused router still allows burns. This prevents governance capture from trapping user funds. The home chain release still requires MPC signature, so a burn during pause creates a pending release that completes when the home chain MPC processes it. + +4. **Undercollateralization detection**: The `totalLocked` / `totalMinted` accounting is per-router-instance. Cross-chain accounting relies on Warp message finality. A race condition between lock on chain A and mint on chain B is bounded by Lux finality (sub-second). + +5. **Governor cannot mint**: The separation between fee governance and mint authority is enforced at the contract level. Even a compromised governor cannot inflate supply. + +6. **Daily limits**: Per-chain daily volume limits bound the blast radius of a compromised MPC group to at most `maxBridgeAmount` per transaction and `dailyLimit` per day per chain. + +## Reference + +| Resource | Location | +|---|---| +| OmnichainRouter contract | `github.com/luxfi/teleport/contracts/OmnichainRouter.sol` | +| LP-003 Securities Bridge | `LP-003-securities-bridge.md` | +| LP-019 Threshold MPC | `LP-019-threshold-mpc.md` | +| Teleport Bridge Architecture | `lp-6332-teleport-bridge-architecture-unified-cross-chain-protocol.md` | +| Bridged Asset Standard | `lp-3800-bridged-asset-standard.md` | + +## Copyright + +Copyright (C) 2024-2026, Lux Partners Limited.

Per-Chain Implementation Details + +#### 4.1 Solana (Anchor/Rust) + +```rust +#[program] +pub mod teleport_bridge { + pub fn lock(ctx: Context, amount: u64, dest_chain_id: u64, dest_address: [u8; 32]) -> Result<()>; + pub fn burn(ctx: Context, amount: u64, dest_chain_id: u64) -> Result<()>; + pub fn bridge_mint(ctx: Context, recipient: Pubkey, amount: u64, + source_chain_id: u64, nonce: [u8; 32], sig: [u8; 64]) -> Result<()>; + pub fn bridge_release(ctx: Context, recipient: Pubkey, amount: u64, + source_chain_id: u64, nonce: [u8; 32], sig: [u8; 64]) -> Result<()>; +} +``` + +Signature verification uses the Solana Ed25519 program (`Ed25519SigVerify111111111111111111111111111`) via CPI. The aggregate FROST public key is stored in a PDA (program-derived address). + +Nonce tracking uses a PDA per nonce: `seeds = [b"nonce", nonce.as_ref()]`. If the PDA account exists, the nonce has been processed. + +#### 4.2 TON (FunC) + +```func +() recv_internal(int msg_value, cell in_msg_full, slice in_msg_body) impure { + int op = in_msg_body~load_uint(32); + if (op == op::lock) { ... } + if (op == op::burn) { ... } + if (op == op::bridge_mint) { ... } + if (op == op::bridge_release) { ... } +} +``` + +Signature verification: TON natively supports Ed25519 via the `check_signature(hash, signature, public_key)` built-in. The aggregate FROST key is stored in contract storage cell. + +Nonce tracking: dictionary (hashmap) in contract storage. Key = nonce hash, value = 1. + +#### 4.3 Sui (Move) + +```move +module teleport::bridge { + public entry fun lock(bridge: &mut Bridge, coin: Coin, dest_chain_id: u64, dest_address: vector, ctx: &mut TxContext); + public entry fun burn(bridge: &mut Bridge, coin: Coin, dest_chain_id: u64, ctx: &mut TxContext); + public entry fun bridge_mint(bridge: &mut Bridge, recipient: address, amount: u64, + source_chain_id: u64, nonce: vector, sig: vector, ctx: &mut TxContext); +} +``` + +Sui supports Ed25519 signature verification via `sui::ed25519::ed25519_verify`. The bridge is a shared object with dynamic fields for nonce tracking. + +#### 4.4 Cardano (Aiken) + +Cardano uses UTXO datum/redeemer: + +```aiken +type Redeemer { + Lock { amount: Int, dest_chain_id: Int, dest_address: ByteArray } + Burn { amount: Int, dest_chain_id: Int } + BridgeMint { recipient: Address, amount: Int, source_chain_id: Int, nonce: ByteArray, sig: ByteArray } + BridgeRelease { recipient: Address, amount: Int, source_chain_id: Int, nonce: ByteArray, sig: ByteArray } +} + +type Datum { + signer_key: ByteArray, + total_locked: Int, + nonces: List, +} +``` + +Ed25519 verification uses Cardano's `verifyEd25519Signature` built-in (Plutus V2+). The bridge validator script enforces that mints match the MPC signature and nonce is not in the datum's nonce list. + +#### 4.5 XRPL (Hooks/C) + +```c +int64_t hook(uint32_t reserved) { + uint8_t op[4]; + hook_param(SBUF(op), "op", 2); + + if (UINT32_FROM_BUF(op) == OP_LOCK) { /* ... */ } + if (UINT32_FROM_BUF(op) == OP_BRIDGE_MINT) { + // Verify secp256k1 signature via util_verify + uint8_t sig[72], pubkey[33], hash[32]; + // ... load from hook params ... + int64_t result = util_verify(SBUF(hash), SBUF(sig), SBUF(pubkey)); + if (result != 1) rollback(SBUF("bad sig"), 1); + // ... emit payment ... + } +} +``` + +XRPL Hooks use `util_verify` for secp256k1 ECDSA verification. Nonce tracking via Hook State (key-value store on the ledger entry). + +#### 4.6 Cosmos (CosmWasm/Rust) + +```rust +#[cw_serde] +pub enum ExecuteMsg { + Lock { amount: Uint128, dest_chain_id: u64, dest_address: String }, + Burn { amount: Uint128, dest_chain_id: u64 }, + BridgeMint { recipient: String, amount: Uint128, source_chain_id: u64, nonce: Binary, sig: Binary }, + BridgeRelease { recipient: String, amount: Uint128, source_chain_id: u64, nonce: Binary, sig: Binary }, +} +``` + +CosmWasm provides `deps.api.secp256k1_verify(message_hash, signature, public_key)` for ECDSA verification. Nonce tracking via `Map, bool>` in contract storage. + +#### 4.7 ICP (Rust Canister) + +```rust +#[update] +async fn bridge_mint(recipient: Principal, amount: u64, source_chain_id: u64, + nonce: Vec, sig: Vec) -> Result<(), String> { + // Verify Ed25519 signature using ic_cdk::api::crypto::verify + // ... +} +``` + +ICP canisters use the management canister's `ecdsa_public_key` and `sign_with_ecdsa` for threshold ECDSA, but for verification of incoming FROST signatures, the canister verifies Ed25519 using a Rust crate compiled to WASM (ed25519-dalek). + +#### 4.8 Remaining Chains + +The remaining 10 chains (NEAR, Stellar, Stacks, StarkNet, Algorand, Fuel, Tezos, OP_NET, Polkadot, TRON) follow the same pattern: + +- Native language implementation +- Built-in or library signature verification matching the chain's native curve +- Nonce tracking in contract/program storage +- Lock/mint/burn/release matching the common interface + +Full implementations are in `github.com/luxfi/teleport/programs/`. + +### 5. Message Format + +All chains use the same canonical message format for signature verification: + +``` +message = keccak256(abi.encode( + "TELEPORT_V1", + source_chain_id, + dest_chain_id, + operation_type, // 0x01=lock, 0x02=burn, 0x03=mint, 0x04=release + token_address, // 32 bytes, left-padded for shorter addresses + recipient, // 32 bytes, left-padded + amount, // uint256 + nonce // 32 bytes +)) +``` + +For Ed25519 chains, the message is hashed with SHA-512 as required by the EdDSA specification. For secp256k1 chains, keccak256 is used directly. + +### 6. Relayer Architecture + +Each non-EVM chain has a dedicated relayer service: + +``` +Lux C-Chain (or any EVM) Relayer Service Target Chain +------------------------- ---------------- ------------ +Lock event emitted ---> Watches events ---> Calls bridge_mint + Verifies finality with MPC signature + Requests MPC signing + Formats native tx +``` + +Relayers are stateless Go services (one per target chain) that: +1. Watch for Warp/event messages on source chains +2. Verify finality on the source chain +3. Request a threshold signature from the MPC group (LP-019) +4. Format the transaction in the target chain's native format +5. Submit to the target chain + +Relayers hold no keys. They are message routers. The MPC group holds the signing authority. + +## Security Considerations + +1. **Native verification**: Each program uses the chain's own signature verification. This means the verification code is part of the chain's consensus-critical path and has been audited by the chain's own security processes. No custom cryptography is deployed on-chain. + +2. **Nonce replay**: Every program tracks processed nonces in persistent storage. The nonce includes source chain ID, preventing cross-chain replay. The nonce includes amount and recipient, preventing parameter substitution. + +3. **Account model differences**: UTXO chains (Cardano, Fuel, OP_NET) require the bridge to manage UTXOs rather than account balances. The lock operation consumes input UTXOs and produces a bridge-controlled UTXO. The bridge_release operation produces a new UTXO for the recipient. + +4. **Finality assumptions**: Each relayer waits for source chain finality before requesting MPC signing. Finality thresholds per chain: Solana (32 slots), TON (1 masterchain block), Sui (checkpoint), Cardano (2160 blocks for deep finality, 30 blocks for probabilistic), etc. + +5. **Program upgradeability**: Programs on Solana (upgradeable by default) and CosmWasm (migrate entrypoint) support upgrades. Programs on Sui (immutable by default), Cardano (script hash), and StarkNet (proxy pattern) have different upgrade models. All programs use the chain's standard upgrade mechanism with the governor as the upgrade authority. + +6. **Ed25519 vs secp256k1 choice**: The choice is dictated by the chain's native support. Using the native curve avoids deploying custom precompiles or libraries, reducing attack surface. + +## Reference + +| Resource | Location | +|---|---| +| Teleport programs | `github.com/luxfi/teleport/programs/` | +| LP-016 OmnichainRouter | `LP-016-omnichain-router.md` | +| LP-019 Threshold MPC | `LP-019-threshold-mpc.md` | +| Teleport Token Standard | `lp-3810-teleport-token-standard.md` | +| Teleport Bridge Architecture | `lp-6332-teleport-bridge-architecture-unified-cross-chain-protocol.md` | + +## Copyright + +Copyright (C) 2024-2026, Lux Partners Limited.

With the offset, the initial exchange rate is ~1000 shares per asset, making donation attacks economically infeasible. + +### 3. YieldBridgeVault (Source Chain) + +The YieldBridgeVault is deployed on the source chain (e.g. Ethereum for yLETH).

Yield Reporting via Warp + +Yield accrued on the source chain is reported to the destination chain (Lux) via Warp messaging: + +```solidity +function reportYield() external { + uint256 currentTotal = _sumStrategyBalances(); + uint256 yieldDelta = currentTotal - totalDeposited - totalYieldAccrued; + + if (yieldDelta == 0) return; + + totalYieldAccrued += yieldDelta; + + // Send Warp message to destination chain + IWarpMessenger(WARP_PRECOMPILE).sendWarpMessage( + abi.encode( + YIELD_REPORT_TYPE, + block.chainid, + yieldDelta, + totalDeposited, + totalYieldAccrued, + block.timestamp + ) + ); + + emit YieldReported(yieldDelta, totalYieldAccrued); +} +``` + +On the destination chain (Lux), the yield-bearing token contract receives the Warp message and updates `_totalYieldAccrued`, causing the share-to-asset exchange rate to increase: + +```solidity +function receiveYieldReport(bytes calldata warpMessage) external { + // Verify Warp BLS signature via precompile + (uint256 yieldDelta, uint256 sourceDeposited, uint256 sourceYieldTotal, uint256 timestamp) + = _verifyAndDecodeWarpMessage(warpMessage); + + _totalYieldAccrued += yieldDelta; + lastYieldReport = timestamp; + + emit YieldReceived(yieldDelta, _totalYieldAccrued); +} +``` + +### 7. ShariaFilter + +The ShariaFilter contract classifies yield strategies for Shariah compliance: + +```solidity +enum ShariaClassification { + Halal, // permissible: staking, real economic activity + Haram, // impermissible: interest-based lending + Conditional, // permissible with conditions (e.g. purification of interest component) + UnderReview // awaiting Shariah Advisory Board ruling +} + +contract ShariaFilter { + address public shariahBoard; // Shariah Advisory Board multisig + + mapping(address => ShariaClassification) public classification; + + function classify(address strategy, ShariaClassification c) external onlyShariaBoard { + classification[strategy] = c; + emit StrategyClassified(strategy, c); + } + + function isHalal(address strategy) external view returns (bool) { + return classification[strategy] == ShariaClassification.Halal; + } +} +``` + +The Shariah Advisory Board is a multisig controlled by qualified Shariah scholars. They classify each strategy: + +| Classification | Strategies | Reasoning | +|---------------|-----------|-----------| +| Halal | Lido, Marinade, Jito, Sanctum, BlazeStake, EigenLayer, Symbiotic, Karak, Babylon | Staking/restaking = real economic activity (securing networks), not interest-based lending | +| Haram | Aave, Compound, MakerDAO DSR | Interest-based lending (riba) | +| Conditional | None currently | Reserved for strategies requiring partial purification | +| UnderReview | None currently | Reserved for new strategies pending evaluation | + +Users who opt into Shariah-compliant mode receive yield only from Halal-classified strategies. Their share accounting is separate: + +```solidity +function depositHalal(uint256 amount) external { + // Only allocates to strategies where shariaFilter.isHalal(adapter) == true + // Separate share tracking for halal depositors + // Lower total yield but Shariah compliant +} +``` + +### 8. Rebalancing + +The vault rebalances across strategies based on target allocations: + +```solidity +function _rebalance() internal { + uint256 total = UNDERLYING.balanceOf(address(this)); + for (uint256 i = 0; i < strategies.length; i++) { + if (!strategies[i].active) continue; + uint256 target = (total * strategies[i].allocation) / 10_000; + uint256 current = strategies[i].deposited; + if (target > current) { + _depositToStrategy(i, target - current); + } else if (current > target) { + _withdrawFromStrategy(i, current - target); + } + } +} +``` + +Allocation weights are set by governance and sum to 10000 basis points. + +## Security Considerations + +1. **Inflation attack**: The virtual offset (VIRTUAL_SHARES=1e3, VIRTUAL_ASSETS=1) makes donation-based inflation attacks cost-prohibitive. An attacker would need to donate 1e3x the victim's deposit to steal 50% of their shares. + +2. **Strategy risk isolation**: Each strategy adapter is a separate contract. A bug in one adapter cannot drain funds from other strategies. The vault withdraws from specific strategies, not from a shared pool. + +3. **Per-operation approvals**: No infinite approvals. Each deposit approves exactly the required amount. A compromised adapter can only access funds during the deposit call, not drain the vault. + +4. **Yield reporting integrity**: Yield reports are delivered via Warp messaging with BLS signature verification. A false yield report would require compromising 67%+ of source subnet validators. + +5. **Redeemability guarantee**: Users can always burn yLETH/yLBTC/yLUSD/yLSOL and receive underlying + accrued yield. The exit guarantee from LP-016 applies: burns are never paused. + +6. **Strategy withdrawal risk**: Some strategies have withdrawal queues (EigenLayer unbonding: 7 days, Babylon unbonding: ~10 days). The vault maintains a liquidity buffer (configurable, default 10% of TVL) in the underlying asset to service immediate redemptions. Large redemptions that exceed the buffer enter a withdrawal queue. + +7. **Shariah classification mutability**: The Shariah Advisory Board can reclassify a strategy at any time. If a Halal strategy is reclassified as Haram, existing Halal depositors' funds are withdrawn from that strategy at the next rebalance. No retroactive yield clawback occurs. + +8. **Cross-chain yield lag**: Yield reports are periodic (configurable, default every 4 hours). Between reports, the destination chain's share price lags the source chain's actual yield. This creates a small arbitrage window. The window is bounded by the report interval and the rate of yield accrual (typically <0.01% per 4 hours). + +## Reference + +| Resource | Location | +|---|---| +| YieldBridgeVault contract | `github.com/luxfi/teleport/contracts/yield/YieldBridgeVault.sol` | +| ShariaFilter contract | `github.com/luxfi/teleport/contracts/yield/ShariaFilter.sol` | +| Yield adapters | `github.com/luxfi/teleport/contracts/yield/adapters/` | +| LP-016 OmnichainRouter | `LP-016-omnichain-router.md` | +| LP-019 Threshold MPC | `LP-019-threshold-mpc.md` | +| Warp Messaging 2.0 | `lp-6022-warp-messaging-20-native-interchain-transfers.md` | + +## Copyright + +Copyright (C) 2024-2026, Lux Partners Limited.

Three protocols are used: FROST (Schnorr/EdDSA, 2-round, for Ed25519 chains), CGGMP21 (ECDSA, identifiable aborts, for secp256k1 chains), and LSS (Linear Shamir's Secret Sharing, wraps both, enables dynamic resharing). The MPC group produces a single aggregate signature per signing request. On-chain verification uses Lux EVM precompiles: FROST at 0x000C, CGGMP21 at 0x000D, and Ringtail (post-quantum) at 0x000B. LSS enables dynamic resharing (e.g. 3-of-5 to 5-of-7) in 0.14ms per party without reconstructing the secret key. + +The MPC ceremonies in this LP are hosted on **M-Chain (MPC, see +LP-134)**. TFHE bootstrap-key generation is hosted on **F-Chain (FHE +keygen, see LP-134)** and consumes M-Chain ceremony output via the +shared `thresholdvm` substrate. + +## Motivation + +Bridge security depends on the signing infrastructure. A single private key is a single point of failure. Traditional multisig (N-of-M with individual signatures) is expensive on-chain (gas scales linearly with M) and leaks the signer set. + +Threshold MPC solves both problems: +1. The private key never exists in one place -- each signer holds a share +2. The MPC group produces a single signature indistinguishable from a regular signature +3. On-chain verification cost is constant regardless of group size +4. Identifiable aborts (CGGMP21) ensure malicious signers are detected and excluded +5. Dynamic resharing (LSS) allows adding/removing signers without a new DKG ceremony + +## Specification + +### 1.

Key Rotation via LSS Resharing + +When the OmnichainRouter proposes a signer rotation (LP-016, 7-day timelock): + +``` +Day 0: Governor calls proposeSignerRotation(newGroupKey) +Day 0-7: LSS resharing executes in background + - Old group (t_old, n_old) reshares to new group (t_new, n_new) + - 0.14ms per party per reshare + - Group public key unchanged + - New signers receive their shares + - Old shares invalidated +Day 7: executeSignerRotation() activates on-chain + - Contract updates signerGroupKey to newGroupKey + - New group is now the active signing group +``` + +The resharing happens off-chain during the timelock window. By day 7, the new group is ready. The on-chain `executeSignerRotation()` simply updates the contract's reference to the group key. + +## Security Considerations + +1. **Key share isolation**: Each signer's key shares are stored in HSM. The full secret key is never reconstructed, not even during signing. A compromise of t-1 signers reveals nothing about the secret key. + +2. **Identifiable aborts (CGGMP21)**: If a signer attempts to produce an invalid signature share, the protocol identifies them. The identified signer is excluded and the signing retries. This prevents denial-of-service by malicious signers. + +3. **Nonce reuse prevention (FROST)**: FROST signers generate fresh nonces for every signing session. Nonce reuse in Schnorr/EdDSA reveals the private key. The implementation uses a deterministic nonce derivation (RFC 6979-like) seeded by the message and a per-session random value, preventing reuse even under partial state rollback. + +4. **Pre-signature security (CGGMP21)**: Pre-signatures are bound to the nonce point R. A pre-signature cannot be repurposed for a different signing session. Pre-signatures expire after a configurable timeout (default: 1 hour). + +5. **Resharing security (LSS)**: During resharing, the old group must have t_old honest participants. If fewer than t_old old signers participate, resharing fails (liveness issue, not safety issue). The new group's shares are fresh -- compromising old shares after resharing reveals nothing. + +6. **Post-quantum readiness**: Ringtail (0x000B) provides a post-quantum signing path. The bridge can be configured to require dual signatures (classical + Ringtail) for high-value transfers, providing security if either scheme holds. + +7. **Coordinator compromise**: The coordinator sees signing requests but not key shares. A compromised coordinator can delay or drop signing requests (liveness attack) but cannot forge signatures (safety). Coordinator redundancy (multiple stateless instances) mitigates liveness risk. + +8. **Gas cost comparison**: Threshold MPC verification is more expensive than plain ecrecover (50K-75K vs 3K gas) but cheaper than N-of-M multisig verification (3K * M gas for M individual signatures). For a 5-of-7 group, threshold MPC saves 5x in gas. + +## Operational Authority (Quasar 3.0) + +LP-019 specifies the **protocols** (FROST, CGGMP21, LSS, Ringtail-general). The +**operational chain** that hosts these ceremonies is **M-Chain (MPC, see +LP-134)** (`lux:mpc`), established by LP-134 (Lux Chain Topology) at +the Quasar 3.0 activation on 2025-12-25. Prior to that activation, +ceremonies ran on the legacy T-Chain custody layer (LP-5013, now +deprecated by this LP and LP-134).

Transfers are standard X-Chain `BaseTx` consuming and +producing `NFTTransferOutput`s. No EVM, no contract. + +Seats are: + +- **Transferable** on X-Chain like any native asset, subject to the stake + lock (NFT is locked while its holder is an active validator + unbonding + period of 21 days). +- **Issued** at genesis (initial 100 seats) to vetted operators.

Self-bond first (up to 100% of offense penalty) +2.

A + round straddling the boundary uses the prior epoch's VK; this is + enforced by selecting `zchain_vk_root` from the round's descriptor, + not from a global pointer. +7. **No trusted setup for application VKs**: Halo2, Plonky2, Risc0, + and STARK do not require trusted setups.

The Go canonical at `github.com/luxfi/ringtail` is the byte-exact production reference: every C++/Metal/CUDA/WGSL port MUST reproduce its `WriteTo` byte stream and `Verify` accept set bit-for-bit. + +Ringtail is the post-quantum lane of Lux Quasar triple consensus (LP-020): each block carries a BLS12-381 aggregate (LP-075) for the classical fast path, a Ringtail aggregate for PQ liveness, and an ML-DSA-65 identity proof (LP-070). Ringtail's linear share aggregation removes the Paillier MtA cost of CGGMP21 ECDSA threshold signing while remaining quantum-secure. + +The canonical parameters, ring construction, and serialization are normative.

Input layout: + +``` +mac_input = int64-BE(prover_id_or_verifier_id) // partyID when generating, otherPartyID when verifying + || MACKey[32] + || Matrix[Poly].WriteTo(D_i) + || int64-BE(sid) + || int32-BE(|T|) + || int32-BE(t_k) for t_k in T (in order) +MAC = BLAKE3(mac_input)[:32] +``` + +The asymmetry between generate and verify (the generator embeds `partyID`, the verifier embeds `otherPartyID`) is deliberate: the MAC is over "I, generator, claim D was sent under MACKey shared with you" — verification recomputes with the same identity in slot 0. + +#### 5.7 Hash and PRF Input Formats + +`Hash` (transcript), `LowNormHash` (challenge), `GaussianHash` (`u`), `PRF` (mask): + +``` +Hash = BLAKE3( + Matrix[Poly].WriteTo(A) || Vector[Poly].WriteTo(b) + || int64-BE(sid) || int32-BE(|T|) || (int32-BE(t_k))×|T| + || Matrix[Poly].WriteTo(D_0) || ... || Matrix[Poly].WriteTo(D_{|T|-1}) +)[:32] + +LowNormHash_seed = BLAKE3( + Matrix[Poly].WriteTo(A) || Vector[Poly].WriteTo(b̃) + || Vector[Poly].WriteTo(h̃) || []byte(μ) +)[:32] +c = TernarySampler(BLAKE2-KeyedPRNG(LowNormHash_seed), R, Ternary{H: 23}).Read() +c ← NTT(c); c ← MForm(c) + +GaussianHash_seed = BLAKE3(hash || []byte(μ))[:32] +u' = SamplePolyVector(BLAKE2-KeyedPRNG(GaussianHash_seed), R, + DiscreteGaussian{σ_U, B_U}, len=Dbar, NTT=true, Mont=true) + +PRF_seed = BLAKE3(k_PRF || sd_ij || hash || []byte(μ))[:32] +mask = SamplePolyVector(BLAKE2-KeyedPRNG(PRF_seed), R, + UniformSampler, len=n_vec, NTT=true, Mont=true) +``` + +Notes: +* `binary.Write(BigEndian, hash)` on a `[]byte` writes the raw bytes (Go reflection on slices). `LowNormHash` then writes `mu` via `binary.Write(BigEndian, []byte(mu))` which is identical to `buf.WriteString(mu)` — these MUST be byte-equal across implementations. +* `BLAKE3` is the `github.com/zeebo/blake3` Go binding; output truncated to 32 bytes (`primitives/hash.go:30, 70, 89, 119, 162, 191`). + +#### 5.8 Discrete Gaussian Sampler + +`ring.GaussianSampler` (`lattice/ring/sampler_gaussian.go:48`) uses Marsaglia's Ziggurat algorithm (128 strata) over a BLAKE2-XOF byte stream. Per coefficient: `randU32` (8 bytes consumed; 4 used) for the strata index/sign, then 8-byte `randF64` consumed if a tail rejection occurs. Per-coefficient PRNG byte budget bounds: + +| Path | Bytes consumed | +|------|----------------| +| Common case (>99%) | 8 (one `randU32`) | +| Strata 0 tail loop | 8 + 16·k (one `randU32` + `k` rejection rounds at 16 bytes each, geometric in tail probability) | +| Inter-strata reject| 8 + 8 (one extra `randF64`) | + +The Karney/CDT discussion in earlier drafts is INCORRECT for this canonical: Lattigo uses Ziggurat. C++/GPU ports MUST replicate Ziggurat with the same `wn`, `kn`, `fn` tables (`lattice/ring/sampler_gaussian.go:267-358`) AND the same PRNG byte-stripe layout. + +#### 5.9 Ternary Sampler + +For challenge `c` with `Ternary{H: Kappa=23}`, `TernarySampler.sampleSparse` (`lattice/ring/sampler_ternary.go:198`): + +``` +1. Initialize index list [0, 1, ..., φ-1]. +2. Read ⌈Kappa/8⌉ random bytes from PRNG (sign bits, MSB-first within byte). +3. For i = 0..Kappa-1: + a.

Swap index[p] and index[φ-i-1]; decrement available slots. +4. All other positions remain 0. +``` + +Output is in standard form; Ringtail then applies `NTT` + `MForm`. C++/GPU ports MUST mirror this rejection-sampling loop including the byte-stripe ordering. + +### 6. Security + +#### 6.1 Hardness Assumption + +Module-LWE over `R = Z_q[X]/(X^256+1)` with secret distribution `χ_E = D(σ_E ≈ 6.11)` and dimension `(M=8, n_vec=7)`. The scheme reduces to MLWE in a similar profile to Dilithium / ML-DSA-44 but at a smaller dimension because the threshold setting amortizes signing across `K` parties and the verifier checks an L2-bounded `Δ` instead of an `(α, β)`-bounded `(z, h)`. + +#### 6.2 Concrete Security + +The Ringtail paper (IEEE S&P 2025) targets ≥128-bit classical and ≥120-bit quantum security at the parameter set above. The canonical does not include a primal/dual lattice-attack estimator; LP-070 §6 provides comparable estimates for ML-DSA-44 (`q = 8 380 417`, `n = 256`, `k = 4`, `l = 4`). + +#### 6.3 Identifiable Abort + +Round 2 Preprocess (§4.2) MAC-verifies every `D_j` and rejects on first failure. The `FullRankCheck` over every coefficient slot of `D_Σ` rules out the residual class of malicious commitment messages that pass MAC but admit a re-opening attack. A failing `Verify` after a successful Round 2 indicates a corrupt `z_j` from one of the open shares; the canonical does not yet ship the share-by-share re-verify routine that would identify the cheater, this is future work (see §10). + +#### 6.4 Side-Channel Posture + +`ring.MRed` and `ring.MRedLazy` are constant-time on a 64-bit `bits.Mul64` substrate (Go and C++ on x86/ARM 64). The Ziggurat and ternary samplers contain a rejection-sampling loop whose iteration count depends on the random bytes consumed — these are NOT constant-time in the timing sense, but the PRNG seed is independent of the secret in all call sites except `PRNGKey(skShare)` (`primitives/hash.go:19`), where the BLAKE3 hashing is constant-time. + +#### 6.5 Nonce Reuse + +`r*` and `R_i` are sampled fresh per signing session. The canonical re-derives the per-session PRNG from `BLAKE3(WriteTo(sk_i))` (`sign.go:103`) — this means the same `(sk_i, sid, μ)` tuple deterministically produces the same `R_i` sequence and is therefore SAFE only when `sid` is unique per `(party_id, signing-session)`. Implementations MUST guarantee unique `sid` per session, e.g., monotonic counter + epoch tag. + +### 7.

KAT generator: `cmd/ringtail-kat/main.go` (to be added; see §10). +3. **Negative cases**: corrupted `MAC`, corrupted `z_j`, modified `μ`, modified `b̃` MUST all reject. +4. **Wire byte-equality**: `Vector[Poly].WriteTo` and `Matrix[Poly].WriteTo` outputs MUST hash to identical SHA-256 across Go canonical and C++ port for all 16 KAT inputs.

Open Problems / Future Work + +1. **Identifiable abort completion**: ship `IdentifyCheater(round2_data)` that re-verifies each `z_j` against `(D_j, λ_j, c, b̃)` and returns the first failing `j`. Currently `Verify` only reports global accept/reject. +2. **GPU acceleration**: `MatrixMatrixMul` of `A · R̂` (`M×n_vec × n_vec×Dbar+1`) is the dominant Round 1 cost. Metal/CUDA kernels under LP-137 GPU substrate; crossover threshold `N* = 1` expected based on FHE NTT measurements (LP-137-BENCHMARKS). +3. **DKG without trusted dealer**: replace `sign.Gen`'s trusted-dealer Shamir with Pedersen DKG over `R_q`. LP-019 §5 sketch; full spec pending. +4. **Cross-implementation KAT**: `cmd/ringtail-kat/main.go` generator + `ringtail/test/kat/*.json` to be authored; SHA-256 manifest seals the Go ↔ C++ ↔ GPU byte-equality contract. +5. **Concrete-security estimator**: integrate `lattice-estimator` (Albrecht et al.) inside `cmd/ringtail-params/main.go` to print primal/dual attack costs at the canonical `(M=8, n_vec=7, σ_E)` parameter set. +6. **Round-1 piggyback**: precomputable phase (`A · R̂`, MAC keys, FullRankCheck of own contribution) can run before the message arrives.

Without it, there is no validator set, no staking, no chain creation. Every node that participates in the Lux network must validate the P-Chain. + +### Why Q is required by default + +Post-quantum security is a network-wide property, not a per-chain feature. If validators can opt out of Q-Chain, the quantum finality guarantee degrades. Making Q-Chain critical by default ensures the network maintains its post-quantum security posture. + +### Why C/X are NOT required + +The C-Chain and X-Chain are application-layer chains, not consensus infrastructure.

A node drain, OOM kill, or rolling update destroys local state. PVCs mitigate this but introduce scheduling constraints and cross-AZ reattach latency. +2. **Per-org SQLite**: Base services maintain one SQLite file per tenant organization. A single ATS pod may hold 50+ SQLite databases. PVC-based backup does not scale. +3. **ZapDB volatility**: ZapDB is an in-memory KV store with periodic snapshots. Without continuous replication, a crash loses all state since the last snapshot. +4. **Compliance**: SEC Rule 17a-4, FINRA 4511, and MiFID II require immutable audit trails. Encrypted off-site replication satisfies the "separate storage" requirement. +5. **Post-quantum readiness**: Current X25519 encryption is vulnerable to harvest-now-decrypt-later attacks.

Adding a new primitive (Falcon, SLH-DSA, novel +threshold scheme) requires one enum value plus one verifier function. +The wire ABI never breaks (LP-020 §QuasarCertIngress (offset, len) +indirection). + +## 1. Gateway lane-affinity pinning + +### Routing function + +Hanzo Gateway's existing sticky-session routing extends naturally: + +``` +gpu_id = H(user_lane_id) mod num_gpus +gateway_route = gpu_owner_of(gpu_id) +``` + +`user_lane_id` is the dominant lane key for that user — typically: + +``` +user_lane_id = H("acct", user_id) // balance + nonce dominates +user_lane_id = H("trader", user_id) // for DEX users +user_lane_id = H("collection", coll_id, owner) // for Base apps +``` + +The gateway maintains a route table keyed by `lane_id` and consults it +on every request. Reads from owned lanes are local; writes that span +lanes degrade to distributed-tx (LP-010 §4.0 fragment roots). + +### Properties + +- **Consistency**: same `user_lane_id` always maps to the same node + within an epoch. +- **Smooth rotation**: epoch boundary reshuffles ownership per + `pchain_validator_root`; gateway picks up the new map atomically. +- **Bounded reshuffle**: adding/removing a node only relocates `1/n` + of users (consistent-hash property). +- **Cross-lane writes**: gateway issues distributed-tx via the + CertLane mechanism — fragment roots aggregate into one cert. + +### Where lane-affinity belongs + +In the **gateway**, not in Quasar core. Quasar exposes +`lane_id → gpu_id` as a deterministic function; gateway / Base / MPC / +KMS all consume it. Mock layout: + +``` +~/work/hanzo/gateway/ + src/lane_affinity.rs // route table + epoch-rotation hook + src/quasar_client.rs // calls into LP-132 QuasarGPUEngine +``` + +## 2.

When +Tier 1 passes, the transaction commits without consulting the per-key +version chain. Tier 2 (key-MVCC) and Tier 3 (semantic reducers) only +fire when Tier 1 disagrees. + +## Semantic reducers Tier 3 + +Tier 3 commits commutative operations as `DeferredOp`s rather than as +SSTORE conflicts. The kernel records the operation kind and payload at +execute time and runs `deterministic_reduce_at_commit()` per-lane at +horizon time. Commit order across reducer entries within a single lane +is canonical; across lanes is horizon-determined. + +```cpp +enum class DeferredOpKind : uint8_t { + Add = 0, + Sub = 1, + Append = 2, + BalanceDelta = 3, + FeeAccumulate = 4, + OrderAppend = 5, + AuctionMatch = 6, + MintCounter = 7, + NonceAdvance = 8, +}; + +struct DeferredOp { + uint32_t tx_id; + DeferredOpKind kind; + Hash lane_id; + uint8_t payload[48]; +}; +``` + +DEX hot paths — order append, fee accumulation, volume accumulation, +audit append, per-account net settlement — commit as reducer entries +rather than as same-key SSTORE conflicts. This is the change that makes +the `repair_amplification < 1.01` target stick on regulated-DEX +workloads. + +## ConflictSpec ABI + +Block-STM was blind optimism. ConflictSpec turns it into optimism with +an oracle: the scheduler reads declared/predicted lane sets from +several sources and falls back to speculative STM only on `Unknown`. + +```cpp +struct ConflictSpec { + uint32_t tx_id; + uint32_t read_lane_offset; + uint16_t read_lane_count; + uint32_t write_lane_offset; + uint16_t write_lane_count; + uint32_t commutative_lane_offset; + uint16_t commutative_lane_count; + uint8_t confidence; + uint8_t source; +}; + +enum class ConflictSpecSource : uint8_t { + Static = 0, // compile-time ABI declaration + ABI = 1, // EVM ABI hint (Solidity attribute) + Historical = 2, // observed past traces + UserDeclared = 3, // signed declaration from sender + Precompile = 4, // precompile self-declaration + Learned = 5, // device-resident predictor +}; +``` + +Scheduler precedence: **Static > ABI > UserDeclared > Precompile > +Historical > Learned > fallback Block-STM**. ConflictSpec is *advice*; +correctness is preserved by the underlying validation tiers. + +## LaneClass (NEMO) + +Lanes are classified per round. The classification drives validation +policy and dynamic versioning mode. + +```cpp +enum class LaneClass : uint8_t { + Owned = 0, // account-local / nonce-local / private state + Shared = 1, // shared contract state, ordinary contention + HotShared = 2, // AMM reserves, order-book level, fee counter + Commutative = 3, // additive / append / reducer lane + Unknown = 4, // fall through to ordinary speculative path +}; +``` + +| Class | Validation policy | Versioning mode | +|---|---|---| +| `Owned` | no validation against unrelated txs | `SingleVersionFast` | +| `Shared` | ordered MVCC (Tier 2) | `MultiVersion` | +| `HotShared` | semantic reducer / serialized lane / precompile | `Reducer` or `Serialized` | +| `Commutative` | Tier 3 reducer commit | `Reducer` | +| `Unknown` | ordinary Block-STM speculative path | `MultiVersion` | + +LaneClass is the architectural reason the Tier 1 / Owned-lane fast path +works at all: skewed regulated-DEX workloads have a heavy `Owned` and +`Commutative` tail, exactly where the fast path applies. + +## Dynamic versioning (Multiverse) + +Always-on multi-versioning is expensive in low-contention regions and +unsafe in pathological hot regions. 4.0 ships per-lane mode selection: + +```cpp +enum class VersioningMode : uint8_t { + SingleVersionFast = 0, // low contention; no MVCC chain + MultiVersion = 1, // standard ordered MVCC + Reducer = 2, // commutative fast path + Serialized = 3, // pathological hot lane: strict canonical order +}; +``` + +Mode is published per `LaneClockEntry`. Mode upgrades / downgrades happen +between rounds based on hot-lane telemetry; in-round mode is fixed. + +## Fiber checkpoints + +EVM fibers checkpoint after each `CALL`-frame return and after each +explicit checkpoint opcode. On Tier 1 / Tier 2 conflict, repair re-executes +from the latest checkpoint that precedes the conflicting read, not from +the transaction start. + +```cpp +struct FiberCheckpoint { + uint32_t fiber_id; + uint32_t pc; + uint64_t gas_remaining; + uint16_t stack_depth; + uint16_t mem_size; + Hash state_digest; // commitment over MVCC reads since start +}; +``` + +Measured cost reduction on router / multi-hop swap workloads: +**5–30× repair cost** vs full re-execute. Storage cost is bounded by a +per-fiber ring of last-N checkpoints (default N=4). + +## Commit horizon + +Commit horizon finalises contiguous Nova prefixes or valid Nebula causal +cuts in batches, slashing per-transaction certificate overhead. The +horizon advances when the prefix / cut is fully committable: every +transaction in it has passed Tier 1 / 2 / 3, no repair is outstanding, +and reducer entries are reduced. + +```cpp +struct CommitHorizon { + uint64_t prefix_len; // Nova + Hash causal_cut_root; // Nebula + Hash reducer_state_root; // post-reduce snapshot + uint64_t round_index; +}; +``` + +Per-round, horizon advance emits one set of root materials +(`block_hash`, `state_root`, `receipts_root`, `execution_root`, +`mode_root`, `hint_roots`) — not one per transaction. + +## MVCC GC + +MVCC GC reaps versions that the commit horizon has overwritten and that +no in-flight repair could re-read. + +```cpp +void mvcc_gc(VersionBlock* vb, uint64_t horizon_round) { + // keep the last K versions visible-before(horizon_round) + // drop the rest into a per-round arena that resets at end_round() +} +``` + +The per-round arena resets on `end_round()`. There is no global allocator +on the round path; allocations are stack-bounded. + +## Motor VersionBlock + +Motor (OSDI 2024) lays versions out as consecutive tuples so that one +RDMA round trip / one GPU memory transaction returns all likely-visible +versions for a key. + +```cpp +constexpr int MAX_INLINE_VERSIONS = 8; + +struct VersionBlock { + Hash key; + uint16_t count; + uint16_t capacity; + uint8_t pad[28]; + StmVersion versions[MAX_INLINE_VERSIONS]; // 4 in 3.0; 8 in 4.0 +}; +``` + +VersionBlock is RDMA / multi-GPU friendly. The CSMV commit-server uses +it as the unit of validation message between fiber clients and the +commit server. + +## A/B/M/F drain services + +4.0 grows the GPU service set from 12 (LP-132) to 16: + +```cpp +enum class ServiceId : uint32_t { + // 3.0 services (12) + Ingress = 0, + Decode = 1, + Crypto = 2, + DagReady = 3, + Exec = 4, + Validate = 5, + Repair = 6, + Commit = 7, + StateRequest = 8, + StateResp = 9, + CertLane = 10, + CertOut = 11, + + // 4.0 services (4 new) + AdaptiveSchedule = 12, // ConflictSpec admission, predictor consult + BridgeAttest = 13, // cross-chain attestation drain + MarketAuction = 14, // auction-rule batched matching for DEX hot lanes + FiberCheckpoint = 15, // checkpoint emit / GC + + Count = 16, +}; +``` + +Each new service has a dedicated ring (header + items arena), the same +back-pressure semantics as the 3.0 services, and the same wave-tick +budget contract. + +## Real BLS / Ringtail / Groth16 verifiers + +The 3.0 cert verifiers were HMAC-keccak with a master secret — real +cryptographic verification (one-way, cross-lane domain tags reject +replay), structured so that the swap to real primitives is a single +function-pointer change. 4.0 makes those swaps: + +| Lane | 3.0 (HMAC-keccak) | 4.0 (real) | Substrate file | +|---|---|---|---| +| BLS | placeholder | **BLS12-381 pairing** kernel (vendored) | `lib/consensus/quasar/gpu/crypto/bls12_381.metal` / `.cu` | +| Ringtail | placeholder | **Ring-LWE share verify** against Q-Chain ceremony key | `lib/consensus/quasar/gpu/crypto/ringtail.metal` / `.cu` | +| Groth16 | placeholder | **Groth16 over BLS12-381** against Z-Chain VK | `lib/consensus/quasar/gpu/crypto/groth16.metal` / `.cu` | + +The verifiers run on-device. There is no CPU fallback on the round +path. The HMAC-keccak path is preserved as a development-only mode for +deterministic test vectors and is gated behind `EVM_DEV_HMAC_VERIFIER=1`. + +## Cross-backend determinism + +A single harness runs every test against both Metal (Apple M1 Max) and +CUDA (NVIDIA H100).

Resource consumption — GPU compute, +storage, bandwidth, FHE bootstraps, AI inference tokens — is priced +per-appchain via on-chain markets and paid in native LUX or +appchain-native tokens. + +The unifying observation: **every cloud workload is a Quasar appchain +preset**. There is no separate cloud stack; the same nine chains +(LP-134) and the same wave-tick GPU kernel (LP-132) run consensus, +DEX, EVM, FHE, AI inference, and customer workloads in lockstep. + +## 1. Decentralization + +### Bitcoin-class permissionlessness + +| Property | Mechanism | +|---|---| +| **Anyone can run a node** | stake LUX on P-Chain, register validator key (LP-015), be eligible for any appchain's validator subset | +| **Anyone can deploy an appchain** | submit `DeployAppchainTx` on P-Chain with a `BaseAppchainConfig` (LP-133); validator subset auto-selects from staked pool | +| **No gatekeeper for tenancy** | appchain ID space is permissionless; collisions resolved by stake-weighted priority | +| **No central operator** | every workload runs across N>2/3 of its appchain's validator subset; loss of any 1/3 is tolerated | +| **Open source** | node, adapter, EVM, FHE, AI inference are MIT/Apache; reproducible builds via `~/work/lux/node` | + +### Validator selection per appchain + +Each appchain's validator subset is committed in the `BaseAppchainConfig` +(LP-133): + +```cpp +struct BaseAppchainConfig { + uint64_t chain_id; + Hash validator_subset_root; // P-Chain commitment + Hash qchain_ceremony_root; + Hash zchain_vk_root; + QuasarMode mode; // Nova or Nebula + uint64_t block_time_ms; + uint64_t gas_limit; +}; +``` + +Subset selection is deterministic from `(P-Chain validator set, +chain_id, epoch)`. Subset size is policy: a tenant may pay for a +larger subset (more decentralization) or a smaller one (cheaper). + +### Failure domain isolation + +Cross-tenant isolation runs at the appchain boundary: + +| Failure mode | Blast radius | +|---|---| +| Validator equivocation | one appchain (signed by validator's stake share) | +| GPU node crash | one appchain's lane subset on that node | +| Network partition | partitioned appchains; others unaffected | +| Smart-contract bug | one appchain's contract space | +| FHE key compromise | one F-Chain key arena; rotated per LP-013 | + +There is no shared mutable cloud-control-plane state across tenants +that could fan a single failure across the customer base. + +## 2. Workload classes + +Every Lux Cloud workload maps to one or more chains in LP-134's +nine-chain topology: + +### 2.1 Stateful services (database, KV, queues) + +Native pattern: **Hanzo Base appchains on Quasar** (LP-133 §2). + +| Concept | Mapping | +|---|---| +| Database table / collection | `domain` component of lane key | +| Row / record | `H("base", chain_id, collection, record_id)` lane | +| Read query | local read from owned lane (gateway routes to owner) | +| Write / mutation | Quasar tx in QuasarGPU adapter | +| Transaction | distributed-tx via per-lane cert artifacts | +| Realtime subscription | tail `CertOut` for subscribed lanes | + +Throughput: LP-132 §Tier 2 (~100 M ops/s on a single GPU node). +Finality: < 1.1 s strong; commit < 50 ms. + +### 2.2 Stateless compute (workers, FaaS) + +Stateless workloads are **C-Chain contracts** (LP-009 GPU-native EVM) +deployed inside the customer's appchain. Cold-start is zero (no +container boot); the EVM fiber executes inside the wave-tick kernel. +Function inputs and outputs are tx calldata and emitted events. + +Auto-scaling: validator subset size determines compute-side capacity; +the customer can scale by paying for a larger subset. Read-side scaling +is automatic via the gateway's lane-affinity routing (LP-133 §1). + +### 2.3 AI inference (HMMs and LLMs) + +Per LP-130, AI inference runs through the Hanzo AI Chain +(`drain_ai` service, forthcoming) that consumes model weights from +content-addressed storage and runs inference inside the QuasarGPU +wave-tick kernel. + +| Pattern | Authority | +|---|---| +| Model loading (weight hash) | content-addressed; pinned by P-Chain stake | +| Inference dispatch | C-Chain precompile call → AI-chain lane | +| Result attestation (proof of correct inference) | A-Chain (LP-134) attestation | +| Token-billed metering | per-inference fee charged to caller's appchain account | + +The inference cert lane is registered alongside the LP-134 lanes +(reserved enum slot ≥ 10). Confidential inference (encrypted weights +or encrypted inputs) routes through F-Chain (`FheCompute` service). + +### 2.4 DEX engines (precompile-native) + +The DEX matching engine is a **C-Chain precompile** (LP-9010), not a +contract. Order books live in lanes (LP-010 lane affinity), match in +the wave-tick kernel, and settle on X-Chain. Lux Cloud DEX customers +get sub-100µs match latency on the same GPU process that serves their +other workloads. + +### 2.5 FHE compute (encrypted services) + +Encrypted workloads run on **F-Chain** (LP-013, LP-066) via the +`drain_fhe` service. Customers pay per TFHE gate evaluation + +bootstrap. Use cases: + +| Use case | LP | +|---|---| +| Confidential ERC-20 (token balances hidden) | LP-067 | +| Private teleport (cross-chain confidential transfer) | LP-068 | +| Encrypted database queries | this LP §2.1 + F-Chain | +| Encrypted ML inference | this LP §2.3 + F-Chain | + +Bootstrap-key material lives in **M-Chain ceremony output → F-Chain +key arena** (LP-013 §key-share ceremonies, LP-076 universal threshold). + +## 3. Resource economics + +### Per-appchain markets + +Each appchain has its own gas / fee curve. The customer chooses: + +| Knob | Effect | +|---|---| +| `gas_limit` | per-block compute budget | +| `block_time_ms` | latency vs. cost trade-off | +| `validator_subset_size` | redundancy / decentralization budget | +| `mode` (Nova / Nebula) | linear order vs. DAG fanout | +| `fee_token` | LUX or appchain-native (must be exchangeable for LUX at the validator level for stake-aligned settlement) | + +Settlement: per-block fees are split between the appchain's validator +subset (compute reward) and the P-Chain global treasury (stake reward ++ slashing pool). Split ratio is policy per LP-080 / LP-083. + +### Per-resource pricing + +Resource consumption is metered at the substrate level — there is no +host-side metering. Every priced operation is a counter inside the +wave-tick kernel: + +| Resource | Counter | Settlement | +|---|---|---| +| EVM gas | per-tx gas used | per-block, in fee token | +| GPU compute (kernel-time) | service-tick count per service | per-block, in fee token | +| Storage (state-trie bytes) | trie-node deltas per block | per-block, in fee token | +| Bandwidth | bytes egressed via gateway | per-billing-window | +| TFHE gates | per-gate counter in `drain_fhe` | per-block | +| Bootstrap | per-bootstrap counter | per-block | +| AI inference tokens | per-token counter in AI lane | per-inference | +| DEX matches | per-match in DEX precompile | per-match | + +All counters live in the same per-tx receipt. No external billing +service is involved on the hot path. + +### Marketplace mechanics + +Validator nodes advertise their resource availability (GPU model, +memory, bandwidth, TEE support) in a P-Chain registry (per LP-129). +When a `DeployAppchainTx` arrives, the subset selector matches the +appchain's resource requirements against advertised capacity. +Oversubscription resolves via stake-weighted bidding within the +selection epoch. + +## 4. TEE integration + +Confidential workloads run inside SGX / SEV-SNP / TDX with quotes +attested to **A-Chain** (LP-134). The pattern: + +1. Tenant deploys a confidential appchain with `tee_required: true` + in `BaseAppchainConfig`. +2. Validator subset selector restricts to TEE-capable nodes. +3. Each node submits a TEE quote (per LP-127, LP-065) on join. +4. Quotes verify via `drain_attest` (LP-134 §A-Chain), commit to + `achain_attestation_root[32]` in `QuasarRoundDescriptor`. +5. Customer contracts can read the attestation root via precompile + and gate sensitive operations on it. + +TEE + FHE together (encrypted execution inside attested enclaves) +provides defense in depth: a TEE compromise alone reveals only +ciphertexts; an FHE compromise alone is irrelevant to data inside +TEEs. + +## 5. Migration / portability + +Appchain state is portable. The mechanism: + +| Step | Action | +|---|---| +| 1 | Customer issues `SnapshotAppchainTx` on their appchain | +| 2 | Validator subset produces a Quasar-cert-protected snapshot at the named round | +| 3 | Snapshot artifact = `(state_root, snapshot_blob_hash, quasar_cert)` committed under M-Chain ceremony root or B-Chain bridge root | +| 4 | New deployment (different chain ID, possibly different validator subset, possibly different cluster) imports the snapshot via `RestoreAppchainTx`, verifying the cert against the source epoch's `QuasarRoundDescriptor` | +| 5 | C-Chain contract addresses, Base records, FHE ciphertexts all preserve identity | + +This is **lift-and-shift portability over a permissionless substrate** +— a stronger guarantee than typical cloud portability, because the +cert provides cryptographic continuity, not just data continuity. + +## 6. Reference implementations + +### Hanzo Cloud (`~/work/hanzo/cloud`) + +The Casibase-derived AI cloud (RAG, embedding providers, vector +search) runs as a Lux Cloud appchain. Each tenant gets: +- A Base appchain for collections (knowledge bases, conversations). +- An AI lane for inference dispatch. +- An F-Chain key arena for confidential RAG queries. + +### Lux Cloud (`~/work/lux/cloud`) + +The reference cloud frontend / dashboard. Next.js + tRPC over +QuasarGPU engine RPCs. Drives appchain deployment, monitoring, and +billing through P-Chain transactions. + +### Lux Cloud Operator + +Cloud-infra orchestration (validator-node provisioning, GPU driver +setup, KMS sync) is performed by `~/work/lux/operator` (the +lux-cloud-operator). Per CLAUDE.md, all cloud infra deployment runs +through the operator + `platform.hanzo.ai` PaaS — devs do not touch +DOKS / GKE directly. + +## 7. Implementation plan + +| Version | Scope | +|---|---| +| **v0.50** | LP-134 chain topology lands (M, F, A, B chains) | +| **v0.51** | `DeployAppchainTx` on P-Chain; validator subset selector | +| **v0.52** | Per-appchain fee markets; receipt metering for GPU + storage | +| **v0.53** | Hanzo Base appchain template (LP-133 §2) ships in operator | +| **v0.54** | F-Chain confidential appchain template | +| **v0.55** | TEE-required appchain template (A-Chain attested) | +| **v0.56** | AI inference appchain template (LP-130) | +| **v0.57** | Snapshot/restore portability flow (this LP §5) | +| **v0.58** | Marketplace registry: GPU/TEE/bandwidth advertisement | + +## 8. Security Considerations + +1. **Stake-aligned validation**: every appchain's validator subset has + stake at risk via slashing on P-Chain. There is no path where a + compromised cloud node profits from misbehavior — slashing exceeds + any rational reward (per LP-084 validator economics). +2. **Tenant isolation by construction**: cross-tenant leakage requires + either equivocation by ≥1/3 of an appchain's validator subset + (slashed) or a substrate bug (in-scope for audit). +3. **Resource accounting integrity**: counters are part of the receipt, + covered by `execution_root`, certified by Quasar. A node cannot + under-report or over-report consumption without producing an + invalid execution root. +4. **Confidentiality**: F-Chain (FHE) and A-Chain (TEE) provide two + independent confidentiality paths. Customers needing both can + stack them. +5. **Snapshot replay**: a snapshot artifact is bound to its + `QuasarRoundDescriptor`; replaying it into a chain with a different + `pchain_validator_root` fails the cert verification at restore time. +6. **Bridge surface**: cross-cloud transfers (e.g., to centralized + cloud) go through B-Chain (LP-134), which inherits all bridge + security properties (LP-016, LP-017, LP-018). There is no privileged + "cloud bridge" with elevated permissions. +7. **DoS resistance**: appchains are economically rate-limited by their + own gas / fee curves; one appchain saturating its subset has zero + effect on other appchains running on the same physical nodes + (lane-level scheduling, LP-132 §wave-tick). +8. **Data sovereignty**: storage layer is the Quasar state trie itself + (committed in `state_root`), not an external object store. No + off-chain data plane, no external availability assumption. + +## Reference + +| Resource | Location | +|---|---| +| Quasar consensus | LP-020 | +| QuasarGPU adapter | LP-132 | +| Quasar app stack | LP-133 | +| Lux chain topology | LP-134 | +| GPU-native EVM | LP-009 | +| FHE / F-Chain | LP-013, LP-066 | +| Threshold MPC / M-Chain | LP-019, LP-076 | +| KMS | LP-062 | +| Z-Chain | LP-063 | +| TEE mesh / attestation | LP-065, LP-127 | +| AI chain | LP-130 | +| DEX engine precompile | LP-9010 | +| Hanzo Cloud (impl.) | `~/work/hanzo/cloud` | +| Lux Cloud (impl.) | `~/work/lux/cloud` | +| Cloud operator | `~/work/lux/operator` | +| Lux node | `~/work/lux/node` | + +## Copyright + +Copyright (C) 2025, Lux Partners Limited and Hanzo AI Inc.

On + the M1 Max integrated GPU the saved per-thread work is matched by + the dispatch overhead, so the speedup is 1.0×; the change is in + place for discrete CUDA hardware where dispatch latency is ~10 µs + not ~1 ms. + +## Honest caveats + +- **xvm did not commit Phase-2.** The size-dependent CPU↔Metal↔WGSL + divergence in v0.55.2 BENCHMARKS.md is therefore unresolved as of + this roll-up. The 4-way determinism contract holds only at the + pinned harness workload until the v0.55.3 fix lands. +- **cevm full-round Metal substrate is structurally CPU-only in + production (cevm v0.46.1, 2026-04-27).** Sweep on M1 Max measured + Metal 0.003×–0.011× CPU at every N within the substrate's 4096-tx + ingress envelope; the wave-tick scheduler floor (~554 ms / 256 + epochs) dominates regardless of N. Threshold-gated dispatch + (`kQuasarSubstrateMetalThreshold = 8192`) sends every production- + sized substrate-only round to CPU; gated path matches direct CPU + byte-equal within ~3% noise. Metal kernel still drives EVM + bytecode interpretation + vote / state-page ingestion (`requires_metal` + hot paths). The v0.45 batched verifier pairings live at the + verifier layer above the scheduler and ship at 9.24× same-msg. +- **cevm V2 EVM kernel SIMD fan-out landed v0.47.2 — slower on M1.** + Buffer-prep fan-out across 32 lanes is byte-equal V1 but measures + 0.33× of V1 (4.5 ms → 13.7 ms) on Apple unified memory. The 32- + threads/tx threadgroup dispatch + skip_host_memset plumbing is + durable substrate for dGPU; on M1 it is correctly disabled by + default. Same shape as aivm v0.59: architecturally correct, + measurable speedup awaits ICICLE-class hardware where PCIe-bound + host→device transfer cost makes the fan-out genuinely faster. +- **Pairing math remains host-CPU** in cevm v0.45 and bridgevm v0.60 + (canonical c-abi body, no exposed blst symbols in production link + graph). Both reach the brief's primary target (≥9× batched). Stage + 5b measurement (2026-04-27, cevm 9ff799fd) shows Metal single- + pairing at N=1 is structurally bounded on M1 Max (~475 ms vs 510 µs + host blst, 930× slower) because the serial Fp12 chain mismatches + the SIMD GPU shape; per-dispatch GPU compute is ~770 µs for a + single-thread Fp12 op. The ≥30× stretch target requires either + Linux+CUDA (`bls_driver_cuda.cpp` stub) where the toolchain doesn't + fight, batched-N parallel kernel saturation (1 warp per pairing on + M1 Max ≥32-way), or algorithmic changes (Karabina compressed cyclo + squarings). +- **aivm v0.59 architectural change is correct but not measurable on + M1 integrated GPU.** The locate+writeback split, the size-sweep + determinism harness extension, and the dGPU-ready dispatch shape + all land; the per-thread parallel savings on M1 are matched by the + ~1 ms dispatch overhead. Discrete CUDA hosts will quantify the + architectural payoff separately. +- **mpcvm xlarge Metal at 0.156× CPU is still slower than CPU.** The + 18.6× vs Phase-1 Metal is the substrate's correctness-preserving + parallelisation budget; the keccak fold remains sequential by + protocol-wire-format constraint, capping the parallelism ceiling. + CPU's vector keccak-f1600 + zero dispatch cost still wins on M1. +- **CUDA path on every chain**: kernels build under nvcc / clang on the + CUDA toolchain. CUDA wall-clock numbers were not collected on this + Apple host. H100 self-hosted runner reports separately. +- **macOS GPU watchdog**: persists. cevm round bench at fast.1024 + contention is dominated by the same `kIOGPUCommandBufferCallbackError + ImpactingInteractivity` events as Phase-1. + +## Conclusion + +**LP-137 invariant fully shipped: GPU-native + Phase-2 GPU-accelerated +on 5 of 6 Phase-2 targets** (PlatformVM 6.5×; cevm BLS batched 9.24×; +BridgeVM batched real pairing 9.5×; MPCVM xlarge 18.6× vs Phase-1 +Metal; AIVM architecture in place). F-Chain's 23.6× holds. X-Chain's +Phase-2 fix did not land in this push. + +Substrate-wide geometric mean lifts from **0.17× (Phase-1) to 0.90× +(Phase-2 / v0.45) → 0.97× (v0.47.1 with pubkey cache)** — a 5.7× lift, +not yet crossing parity. Three measured production workloads now beat +CPU end-to-end (F NTT 23.6×, B-Chain BLS 9.5×, C-Chain BLS 16.51× via +pubkey cache); every participating Phase-2 chain shows ≥2.5× +wall-clock improvement vs its Phase-1 baseline except A-Chain +(architectural change correct, M1 dispatch-bound; dGPU-pending). + +The CPU touches reality.

Single-bit flips in any of the 9 chain roots produce a different + subject (cert-binding holds). +3. Swapping any two roots produces a different subject (canonical + order P/C/X/Q/Z/A/B/M/F is load-bearing). +4. The engine echoes all 9 roots into the result so consumers can + reconstruct the cert subject from the result alone. +5. Tampered descriptors recompute to a different subject than the + engine's echo. + +## Bugs caught + fixed during the v0.59 push (still load-bearing) + +1. **`rotl64(x, 0)` undefined behavior at clang -O2.** `(x >> (64 - + 0))` is UB (shift count equal to or greater than width). Fixed via + the masked form `n &= 63u; (x << n) | (x >> ((64u - n) & 63u))`. + Found independently by PlatformVM, AIVM, MPCVM agents; now applied + uniformly to all five new VMs and audited present in cevm/quasar. +2. **Apple Clang -O3 keccak_f1600 miscompile** for the full-rate + (136-byte) absorb path. Fixed via `__attribute__((optnone))` on + `keccak_f1600`. Found by XVM during 140-byte attestation-leaf + determinism; applied where multi-block keccak is exercised (AIVM + 140-byte attestation leaf, BridgeVM Merkle leaves, MPCVM + ceremony-bound 136-byte rate path). +3. **WGSL `digest_equal_buf` illegal pointer arg.** A `read_write + storage` pointer parameter is not legal in WGSL. Was dead code in + AIVM; deleted. +4. **WGSL reserved keyword `active`** — renamed to `n_active` in AIVM + transition kernel (WGSL spec reserves it for future use). +5. **WGSL `Ceremony` struct stride drift in MPCVM.** Host stride 128 B, + WGSL natural pack 120 B. Fixed by adding an explicit 8-byte + trailing pad field in `mpcvm_kernels_common.wgsl` so all four + backends agree byte-for-byte. + +## v0.60 push (this commit) — what changed + +1. **XVM**: deleted unused `is_zero32` helper (4 dead lines), added one + focused arena-overflow rejection test (`test_tx_arena_full_rejects`, + ~30 LOC). Result: 95.15% → **97.48% line / 92.46% branch**. +2. **AIVM**: realigned per-VM TOTAL methodology to match BridgeVM/XVM + (CPU oracle = TOTAL). Headline: **98.71% line / 94.71% branch**. + No source change in AIVM; documentation parity only. +3.

The +scheme-aware aggregator demuxes at combine time. + +The noise term `e_i` is sampled from a deterministic-given-transcript +stream (sha256-tree over partyKey ‖ ctID ‖ sessionID ‖ operands), so +two independent runs of `PartialDecrypt` for the same inputs MUST +produce byte-equal shares. This is what makes the share-replay audit +possible: any peer can re-run a party's `PartialDecrypt` and check +the bit-for-bit output. + +### Noise proof — placeholder vs production + +Production deployments require a zero-knowledge proof that `e_i` was +drawn from the prescribed distribution within the bound. Without this +proof a malicious party can inject out-of-bound noise to bias the +aggregate ("noise flooding" attack). + +The standard construction is **CDS** (Cramer-Damgard-Schoenmakers +1994) — a non-interactive disjunctive sigma protocol, made +non-interactive by Fiat-Shamir over the same transcript that produced +`ShareRoot`. References: Boudgoust/Scholl 2023 §3.2; VeloFHE 2025. + +This LP ships a **transcript-bound HMAC commitment** as a placeholder. +It is byte-equal across producer and verifier (deterministic given +the share material and transcript) and lets the rest of the threshold +pipeline run end-to-end. The `noise_proof.go` body is exactly the +shape the production CDS proof plugs into; only the inner body +changes. + +**PRODUCTION REQUIRES** replacing `buildNoiseProof` / +`verifyNoiseProof` / `verifyNoiseProofPublic` with a real CDS sigma +protocol over Z_q (BFV/CKKS) or Z_2 (TFHE). The interface and the +verification gate in the aggregator are already in place. The version +tag on the wire format (`NoiseProofVersion = 1`) bumps to 2 when the +real proof ships, and old shares are rejected at aggregation time. + +### Aggregation + +Aggregation re-verifies every share before combining. The +verification path depends on what keys the aggregator holds: + +| Configuration | Verification path | +|---|---| +| `PartyKeys` populated | `VerifyShareWithKey` (symmetric — works against placeholder noise proof) | +| `PartyPubKeys` populated | `VerifyShare` (public — fails until CDS proof ships) | +| neither | structural-only (root + ciphertext id) — tests / debug | + +In committee self-check mode (every M-Chain MPC node holds its own +KeyShare and verifies its own outbound shares plus the peer shares +it has the keys for), `PartyKeys` is the production path. Cross- +committee verification awaits the CDS proof. + +### Mode-aware anchoring + +The threshold service emits `ThresholdTranscriptRoot` regardless of +deployment mode. The caller chooses where it lands: + +- **Primary mode** — `pkg/audit/mchain` POSTs the transcript root in + a batch anchor to M-Chain. +- **Private mode** — `pkg/audit/worm` writes the transcript root to + the local append-only WORM store with cross-replica head verify. + +Both paths are already implemented in `luxfi/mpc/pkg/audit` (sibling +#115). This LP only requires that the threshold service produce the +root in a form both can consume. + +## Quasar precompile integration plan + +The cevm Quasar dispatcher (LP-009 + LP-132) holds a `PrecompileId` +enum that selects which native handler runs for a given precompile +call. To expose `FHEThresholdShare` + `FHEThresholdAggregate` as +EVM-callable precompiles, two enum values must be added: + +```cpp +// cevm/lib/evm/gpu/precompile_service.hpp +enum class PrecompileId : uint32_t { + // ... existing entries ... + FHEThresholdShare = 0x0200'0083, // partial-decrypt request + FHEThresholdAggregate = 0x0200'0084, // aggregate ≥t shares +}; +``` + +Each handler dispatches into the threshold service: + +| Precompile | Inputs | Outputs | +|---|---|---| +| `FHEThresholdShare` | `(ciphertextRoot, sessionID, partyID)` (the PartyClient is selected by the consensus committee binding) | `(share, shareRoot)` ABI-packed | +| `FHEThresholdAggregate` | `(ciphertextRoot, sessionID, threshold, share[])` | `(plaintextHash, aggregateRoot, transcriptRoot, status)` | + +The plaintext itself does not exit the precompile — only its hash. +Callers that need the plaintext invoke the M-Chain RPC path +(authenticated by IAM JWT) and the precompile only emits roots. + +### Coordination with sibling #90 + +Sibling #90 owns the `PrecompileId` enum surface and is currently +in flight (ConflictSpec sibling).

The math layer cannot detect the error; only the decryptor at the +end of the pipeline observes the corruption, often too late to attribute. + +The architectural fix is not "port one kernel." It is to make domain +mismatch **impossible to express**. Per the FHE-GPU architecture spec §18: +"domain tag must match kernel expectation"; per §20: "no untyped buffers." + +This LP defines the canonical types every FHE-GPU kernel and every caller +must use, and the byte-stable Go ↔ C++ layout that lets these types cross +the cgo boundary unmodified. + +## Specification + +### 1. Polynomial domains + +A polynomial buffer in luxfi/lattice lives in exactly one of four +**arithmetic domains**: + +| Variant | Coefficients in | NTT? | Montgomery? | +|--------------------|------------------------|------|-------------| +| `Standard` | `[0, q)` | no | no | +| `Montgomery` | `a*R mod q`, `R=2^64` | no | yes | +| `NTTStandard` | `[0, q)` (eval form) | yes | no | +| `NTTMontgomery` | `a*R mod q` (eval) | yes | yes | + +These four states form a 2x2 grid. Each kernel declares the (Input, Root, +Output) tuple it accepts; dispatch with any other tuple is rejected at the +boundary. + +The Go NTT path in luxfi/lattice (`ring.Ring.NTT`) consumes +`Montgomery` and produces `NTTMontgomery`. Any kernel intending to share +that pipeline must declare the same tuple. Any kernel that expects +`Standard` and `NTTStandard` is the Barrett path; its caller must convert +explicitly via `MForm` / `IMForm`. + +### 2. Type definitions + +Two repos own the canonical definitions: + +#### Go (consumed by luxfi/fhe, luxfi/cevm, luxfi/chains/*): + +`github.com/luxfi/lattice/v7/types` +- `PolyDomain` — `uint8` enum (`Standard=0, Montgomery=1, NTTStandard=2, NTTMontgomery=3`). +- `NTTContext` — 48-byte struct: `{Modulus, MontR, MontR2, QInv, N, ModulusID, TwiddleOffset, InputDomain, RootDomain, OutputDomain, _pad}`. +- `ReductionMode` — `uint8` enum (`Strict=0, Lazy2=1, Lazy4=2, Lazy8=3`). +- `ReductionBudget` — 24-byte struct: `{Modulus, OpsSinceReduce, MaxOpsBeforeOverflow, Mode, _pad}`. + +`github.com/luxfi/fhe/types` +- `FHEScheme` — `uint32` enum (`TFHE=0, FHEW=1, CKKS=2, BFV=3, BGV=4`). +- `FHECiphertextHeader` — 144-byte struct: `{ParamsHash, KeyID, CircuitID, Scheme, Level, N, ModulusCount, Domain, _pad, Reserved}`. +- `FHEPrecompileArtifact` — 232-byte struct: seven 32-byte digest fields + `OpCount` + `FailedCount`. + +#### C++ (consumed by luxcpp/lattice, luxcpp/fhe, MLX/Metal kernels): + +`luxcpp/lattice/include/lux/lattice/types/{domain,reduction}.hpp` +- `lux::lattice::PolyDomain`, `NTTContext`, `ReductionMode`, `ReductionBudget` +- `static_assert` on `sizeof` and `offsetof` for every field. + +`luxcpp/fhe/include/lux/fhe/types/{ciphertext_header,artifact}.hpp` +- `lux::fhe::FHEScheme`, `FHECiphertextHeader`, `FHEPrecompileArtifact` +- `static_assert` on layout, mirroring Go. + +### 3. Validation contract + +Every kernel boundary calls `Validate()` (Go) or `ntt_context_valid()` (C++) +on its `NTTContext` BEFORE dispatch. The validator rejects: + +1. `Modulus == 0` +2. `N` not a power of two, or `N < 2` +3. `RootDomain != InputDomain` (twiddle/operand encoding mismatch — the #121 class) +4. `OutputDomain` inconsistent with the input/forward-NTT transition rule: + - `Standard → NTTStandard` (forward, Barrett path) + - `Montgomery → NTTMontgomery` (forward, Montgomery path) + - `NTTStandard → Standard` (inverse, Barrett path) + - `NTTMontgomery → Montgomery` (inverse, Montgomery path) + +Any other tuple returns `ErrDomainMismatch` and the kernel MUST NOT +dispatch. The Go and C++ validators implement identical rules. + +### 4. Kernel ↔ domain dispatch table + +The accepted (Input, Root, Output) tuples for each kernel family in the +luxfi/lattice + luxfi/fhe stack: + +| Kernel | Input | Root | Output | +|-------------------------------|------------------|------------------|------------------| +| `Ring.NTT` forward (Go) | Montgomery | Montgomery | NTTMontgomery | +| `Ring.NTT` inverse (Go) | NTTMontgomery | NTTMontgomery | Montgomery | +| `metal_ntt.mm` forward (NEW) | Montgomery | Montgomery | NTTMontgomery | +| `metal_ntt.mm` inverse (NEW) | NTTMontgomery | NTTMontgomery | Montgomery | +| `ckks.MulNew` (eval-form mul) | NTTMontgomery | NTTMontgomery | NTTMontgomery | +| `MForm` (Standard → Montgomery) | Standard | n/a | Montgomery | +| `IMForm` (Montgomery → Standard) | Montgomery | n/a | Standard | + +The metal kernel MUST be ported to consume Montgomery operands. Until it +is, dispatching to it with `InputDomain == Montgomery` MUST return +`ErrDomainMismatch`; the caller must fall back to CPU. + +### 5. Lazy reduction modes + +`ReductionMode` and `ReductionBudget` track when a kernel chain may defer +modular normalisation. Reference: VeloFHE §3.2, CAT GPU FHE 2025 §4. + +| Mode | Result range | Modulus cap | Ops before reduce | +|------------------|-------------------|-------------|-------------------| +| `Strict` | `[0, q)` | `q < 2^64` | 1 | +| `Lazy2` | `[0, 2q)` | `q < 2^63` | 2 | +| `Lazy4` | `[0, 4q)` | `q < 2^62` | 4 | +| `Lazy8` | `[0, 8q)` | `q < 2^61` | 8 | + +`SafeBoundFor(mode, modulus)` returns `0` if the modulus exceeds the +mode's cap, forcing the caller down the strict path. `NewReductionBudget` +returns `ErrModulusTooLargeForLazy` for the same condition. Callers +`Charge(n)` after `n` deferred ops and `Reset()` after each +normalisation pass. + +### 6. Ciphertext binding + +Every FHE ciphertext on the wire and in memory carries an +`FHECiphertextHeader`. The header binds the buffer to: + +- **Parameter set** (`ParamsHash`) — degree N, modulus chain, noise sigma. +- **Key material** (`KeyID`) — public key or evaluation key. +- **Circuit / policy** (`CircuitID`) — the program this ciphertext was + produced under. Different circuits produce headers with different + `CircuitID` values; reusing a ciphertext across circuits is detectable. +- **Domain** (`Domain`) — current `PolyDomain` of the buffer. +- **Level + ModulusCount** — multiplicative depth budget. + +`Header.Digest()` returns SHA-256 of the canonical 144-byte encoding. +`Header.MatchesContext(ctx)` returns true iff `N` and `Domain` agree with +the kernel's `InputDomain`. Both are deterministic and tested against +re-runs. + +### 7. Precompile artifact binding + +Each FHE precompile invocation produces an `FHEPrecompileArtifact` with +seven 32-byte digest fields + an op-count pair. This artifact is the +contribution to `fchain_fhe_root` in the QuasarRoundDescriptor (LP-132, +LP-134) and to the FChainTFHE cert lane (LP-013, LP-020 §3.0). + +The `ThresholdTranscriptRoot` is zero unless the precompile participated +in a threshold round; the `AttestationRoot` is zero unless the precompile +was confidential and attestation was requested. Both are detectable via +`IsThreshold()` / `IsAttested()`. + +### 8. Threshold transcript binding into ciphertext lifecycle + +A threshold-decrypted ciphertext is produced by combining partial +decryption shares from a quorum. The lifecycle: + +1. **Encrypt**: caller produces `FHECiphertextHeader{KeyID=H(Pk), CircuitID=H(C)}`. +2. **Compute**: kernel chain operates on the buffer; intermediate headers + carry the same `KeyID` + updated `Domain` + `Level` decremented by + each rescale. +3. **Threshold decrypt**: each share contributes to a transcript; + transcript hash binds into `FHEPrecompileArtifact.ThresholdTranscriptRoot`. +4. **Result**: the cleartext result is bound to the original `CircuitID` + via the precompile artifact, so an off-circuit decryption is detectable + by any verifier. + +The transcript binding closes the loop: a ciphertext produced under +circuit C, decrypted under transcript T, and recorded under +`fchain_fhe_root` proves that exactly the authorised computation +ran on exactly the authorised inputs and was decrypted under the +authorised quorum. + +### 9. Byte-stability invariant (cross-language) + +Every struct defined in this LP MUST have identical byte layout between +Go and C++. Verified by: + +- `unsafe.Sizeof` + offset checks on the Go side. +- `static_assert(sizeof(...) == ..., "...")` + `static_assert(offsetof(...) == ..., "...")` on the C++ side. +- A canonical byte image test: a struct populated with a known pattern is + serialised by both Go and C++ and the byte arrays are compared. + See `lattice/types/cross_lang_test.go::TestNTTContext_CrossLangByteImage` + and `luxcpp/lattice/test/types_test.cpp::test_ntt_context_memcmp`. + +If any layout test fails, it is a STOP-the-line bug. Mismatched layouts +are silently corrupting on the cgo / shared-memory boundary; do not paper +over. + +## Rationale + +### Why a separate `types` package and not types embedded in `ring`? + +The ring package contains arithmetic; the types package contains only +declarations and validation. Separating them avoids a circular import +when `fhe/types` imports `lattice/types` (the ciphertext header references +`PolyDomain`). This is the only Hanzo-philosophy compatible layering: the +type-system layer does not depend on the math layer, the math layer +imports the type-system layer, and the FHE layer imports both. + +### Why no CBOR / external serialisation library? + +The struct layouts are fixed. Canonical encoding is a 144-byte (or 48-byte, +or 232-byte) little-endian dump using `encoding/binary` from the Go +standard library and direct byte manipulation in C++. Adding `fxamacker/cbor` +or any other library duplicates `encoding/binary` for no benefit and +introduces a non-stdlib dependency. Stdlib first. + +### Why `_pad` as an explicit field instead of relying on compiler padding? + +An explicit pad byte / array makes the byte image deterministic across +Go versions, C++ compilers, and platforms. Relying on implicit padding is +non-portable and silently breaks layout tests on architectures with +different alignment rules. + +### Why include `Reserved [24]byte` in `FHECiphertextHeader`? + +Forward-compatible extension. Future fields (e.g. attestation hashes, +transcript pointers) can be promoted from `Reserved` without changing the +byte size of the header. Today, `Reserved` is initialised to zero and +included in `Digest()` so any future repurposing is detectable as a +distinct digest. + +## Backwards compatibility + +This LP introduces a new `types` package; nothing existing imports it +yet. Adoption across luxfi/lattice, luxfi/fhe, luxfi/cevm, and the GPU +kernel paths is staged in subsequent PRs. The type-system PR ships the +types alone — no call-site rewrites are in scope here. Per the project +philosophy: forward-only, no compatibility shims. + +## Reference implementation + +- `lux/lattice/types/` — `domain.go`, `ntt_context.go`, `reduction.go`, `errors.go`. +- `lux/fhe/types/` — `scheme.go`, `ciphertext_header.go`, `artifact.go`. +- `luxcpp/lattice/include/lux/lattice/types/` — `domain.hpp`, `reduction.hpp`. +- `luxcpp/fhe/include/lux/fhe/types/` — `ciphertext_header.hpp`, `artifact.hpp`. +- Tests: `lux/lattice/types/*_test.go`, `lux/fhe/types/*_test.go`, + `luxcpp/lattice/test/types_test.cpp`, `luxcpp/fhe/test/types/types_test.cpp`. + +## References + +- LP-013 — FHE on GPU (F-Chain compute fabric) +- LP-029 — NTT Transform +- LP-066 — TFHE +- LP-132 — QuasarGPU Execution Adapter +- LP-127 — Attestation +- VeloFHE: GPU-Accelerated Lazy-Reduction CKKS, 2024 +- CAT: GPU FHE Compiler with Domain-Aware IR, 2025 +- PR #121 — Metal NTT vs Go Ring.NTT domain mismatch (the bug this LP prevents) + +## Copyright + +Copyright (c) 2026, Lux Industries Inc.

Every chain has a CUDA + Metal + WGSL kernel triple for its hot ops. + The triple is enforced by the byte-equality test in LP-137 (one CPU + canonical, three byte-equal GPU backends). +3. Two non-hot reach-backs exist (A-Chain replay-window, M-Chain + round-transcript). Both go through the StateRequest service so the + GPU hot loop is non-blocking. +4. Two precompile gaps on C-Chain: `point_eval` lacks a CUDA backend + (Metal only) and `modexp`/`blake2f`/`sha256`/`ripemd160`/`bn256` are + currently CPU-only.

Ringtail + FROST + CGGMP21 live in +their own repos (luxfi/ringtail, luxfi/threshold). + +**Layer 2 — GPU kernels (Metal/CUDA/WGSL):** ships full pipeline +for BLS (Metal Stage 1–3 byte-equal blst across 2 746 vectors, +WGSL full Fp tower 1 900 vectors, CUDA stub), Keccak +(KeccakResidencySession on-device with 4-way round cache), secp256k1 +batch_inv (Montgomery on-device, ecrecover Stage A), NTT (Apple +Silicon Metal/MLX, CUDA, OpenFHE on F-Chain), sha256/blake2b/ripemd160 +batched (v0.64, byte-equal CPU oracle, 100 vectors each). v0.65 lands +ed25519 RFC 8032 byte-equal Metal verify (N_threshold=256, 26.7× +speedup at N=4096 on M1 Max), and mldsa/mlkem dispatch-shape Metal +skeletons (full FIPS-204/203 verify dGPU-deferred — same precedent +as aivm v0.59 + V2 EVM kernel where SHAKE/SHA3 chains dominate +M1 per-thread serial work). + +**Layer 3 — C++ port (luxcpp/crypto):** mid-flight. 11 primitives +have actual `/cpp/*.cpp` bodies (attestation, blake2b, bls, +bn254, keccak, kzg, modexp, ripemd160, secp256k1, secp256r1, +sha256). 19 have placeholder `cpp/` dirs awaiting port. The C++ +port is not on the Go path's critical path — Go production runs +through luxfi/crypto today; luxcpp/crypto is the eventual native- +C++ replacement that lets cevm and other C++ binaries dispatch +into Metal/CUDA without Go FFI. + +**Layer 3.5 — C-ABI wiring (luxcpp/crypto//c-abi/):** the +**actual production bottleneck**. Per live FFI probe (2026-04-27, +luxfi/crypto Rust workspace audit), 26 of 28 luxcpp/crypto archives +return `CRYPTO_ERR_NOTIMPL = -5` for cryptographic operations even +when symbols are exported. C++ bodies + Metal kernels may exist +(see §87 sha256/blake2b/ripemd160 Metal pass) but the c-abi shim +does not dispatch to them. Only `lux_keccak256` and +`lux_secp256k1_ecrecover{,_batch}` are confirmed end-to-end working +in production today. **CRITICAL FINDING**: `lux_blake3` symbol +aliases to keccak (returns keccak digest for any input — silent +correctness bug, tracked as #96). Earlier audit reports of +"X/29 working" measured C++ body presence + Metal kernel byte- +equality against published vectors, not the c-abi → body dispatch +chain that production consumers actually call. The wiring sweep +(~5-10 LOC per shim) is the right next step. + +The "GPU is the gap" framing is partially correct: Metal/CUDA/WGSL +kernels for batched-N workloads are one gap (sibling agents +shipping). The other, larger gap is **c-abi wiring** between +canonical C++ bodies and the Rust/Go/cevm consumers — most c-abi +shims today return NOTIMPL stubs. + +The four-kernel template: + +``` +expand_inputs → parallel_eval → reduce_or_batch_verify → commit_root +``` + +This is the canonical shape `gpukit/` formalizes (see +`luxcpp/crypto/gpukit/README.md`): every primitive that consumes a +batch of inputs and produces a commitment has the same skeleton. Step +1 hoists per-input scratch into device-resident arenas. Step 2 fans a +thread per input. Step 3 reduces the per-input outputs (Merkle leaf +hashes, MSM windows, partial sums). Step 4 emits the commitment in +canonical order. Steps 1, 2, 4 parallelize trivially; step 3 is +parallelizable when the reduction is associative (sum, MSM accumulate, +batch-pairing fold) and serial when it is not (Keccak fold, FROST +round chaining, UTXO consumption). + +The four-kernel template is the canonical shape — not the only shape. +Where an operation is structurally serial (canonical fold, locate-by- +collision, round-by-round protocol), the right answer is to split it +so that the parallel work fans out (step 2) and the serial work is the +smallest possible step (step 3 reduced to a 1-thread fold over +precomputed leaves).

The release gate (`Release()`, `release.go:325-387`) only +calls `req.Attestation.Verify(rec.Nonce)` and `policy.Permits(att)`. It NEVER +calls `attestation.CompositeAttestation.VerifyEvidence(ctx, ...)` from +`mpc/pkg/attestation/composite.go:320`, which is the function that actually +invokes `cc/attest.Dispatch` (SEV-SNP chain verify, AMD KDS, VCEK, TCB). +Confirmed by `grep -rn '\.VerifyEvidence(' lux/*.go` returning zero call sites +outside the definition. + +Attack: any worker presenting an in-process struct that satisfies the gate's +4-method interface and returns `(true, nil)` from `Verify()` gets the sealed +session key. The structural type used by the gate and the cryptographically +verified envelope from `cc/attest` are unrelated; the integration seam is +empty. The wins claimed in #222 (go-sev-guest v0.14.1, ARK→ASK→VCEK chain) +exist in the codebase but are dead code w.r.t. the release path. + +Fix hint: gate must (a) require `*attestation.CompositeAttestation`, (b) call +`VerifyEvidence(ctx, opts...)` AND fail closed if any required issuer kind +returns `nil`/error, (c) bind the attestation root to `rec.Nonce`. + +### N2 — [CRITICAL] TFHE fake-threshold guardUnsafe panics in production keygen path + +`threshold/protocols/tfhe/tfhe.go:69-73 + :179 + :282 + :410` add `guardUnsafe()` +which `panic`s unless `LUX_ALLOW_FAKE_TFHE_FOR_TESTING_ONLY=1`. +`mpc/pkg/mpc/tfhe_session.go:154,165` (production wallet keygen) calls +`tfhe.NewKeyGenerator(...)` then `kg.GenerateKeys(...)` *without* setting that +env var. Any operator running `tfhe:keygen:*` will hit a hard panic — the +node crashes inside the keygen goroutine spawned from `node.go:583`. + +This is reachable from the public `/v1/mpc/wallets POST` flow when wallet kind +`tfhe` is selected. DoS: one well-formed API call drops the node. Detectability: +panic is caught by the defer in tfheKeygenSession but the session terminates; +status is "error" with no recovery. + +Worse: an operator who *does* set the env var to silence the panic gets the +documented unsafe behavior — every party stores the full master key +(`tfhe.go:424-431`), `PartialDecrypt` returns an HMAC tag +(`committee.go:283-294`), and `CombineShares` ignores partials and runs single- +party decrypt (`tfhe.go:281-315`). Either way, the production path is broken. + +Fix hint: refuse construction at the API boundary unless the env var is set +*and* the deployment is dev/test. Better: route `mpc/pkg/mpc/tfhe_session.go` +through the real lattice threshold MPC committee per LP-137 §TFHE-REAL- +THRESHOLD-SPEC; remove the fake-threshold call sites entirely. + +### N3 — [HIGH] Pedersen DST split: `NewGenerators` and `DeterministicGenerators` use the WRONG canonical DST + +`crypto/pedersen/pedersen.go:50,54` calls +`bn254.HashToG1(gBytes, []byte("PEDERSEN_G_V1"))` and `"PEDERSEN_H_V1"`. +`crypto/pedersen/pedersen.go:84,90` (DeterministicGenerators) uses +`"LUX_PEDERSEN_G"` and `"LUX_PEDERSEN_H"`. +Only `crypto/pedersen/pedersen_seed.go:13` +(`SeededGenDST = "PEDERSEN_SEEDED_GEN_V1"`) matches the C++/Metal/CUDA/WGSL +canonical at `luxcpp/crypto/pedersen/cpp/pedersen.hpp:47`. + +A Go caller using `pedersen.NewGenerators` or `DeterministicGenerators` +produces commitments that are *NOT* byte-equal to anything the C++/GPU layer +produces. The Metal kernel at `luxcpp/crypto/bn254/gpu/metal/bn254.metal:435` +expects the host to supply G,H as 8-limb buffers — if the host derived them +via the Go default, the kernel computes a commitment under different +generators. Cross-implementation verification silently fails at the boundary. + +Brand-neutral DST sweep was advertised as comprehensive in #196 / LP-137 +§2.8 ("`PEDERSEN_SEEDED_GEN_V1`, not `LUX_PEDERSEN_SEEDED_GEN_V1`") but the +default Go constructor still uses two different DSTs (`PEDERSEN_G_V1`, +`PEDERSEN_H_V1`) and the deterministic constructor still uses the old branded +DST (`LUX_PEDERSEN_*`). One algorithm, three answers — exactly the violation +LP-137 was meant to close. + +Fix hint: collapse to a single DST `PEDERSEN_SEEDED_GEN_V1` with a counter +(0=G, 1..n-1=G_basis, n=H), matching `pedersen_seed.go` and the C++ side. +Delete `NewGenerators` and `DeterministicGenerators` or route them through +the seeded path. + +### N4 — [HIGH] Banderwagon `MultiExpBlinded` runs blinded MSM on the same variable-time backend + +`crypto/banderwagon/multiexp.go:70-127` blinds `k_i → k_i · r` and unblinds +via `r^{q-2}`, but the underlying `MultiExp` at `multiexp.go:24-38` calls +`bandersnatch.MultiExp` which is Pippenger — the same variable-time function +that motivated the blinding. The blinded scalars `k_i · r` are uniform-random +across calls, which DOES break per-call cache trace correlation (the comment +is correct), but it does NOT eliminate the leak that an adversary observing +`k_i · r` traces can derive (if they can ALSO observe `r` or another linear +combination). The construction relies on `r` being secret and unique-per-call. + +Adversarial construction: side-channel attacker that can place a probe AFTER +the blinding step (e.g., correlating the trace of `r.Exp(qMinusTwo)`, line +109) recovers `r`, then cancels: the residual trace from the MSM yields +`k_i`. The Fermat-ladder for `r^{q-2}` is constant-iteration but NOT constant +time on individual square+mul (gnark `Element.Exp` is regular-form ladder over +the bit-pattern of `q-2`, which is a public constant — that's fine — but the +Mul argument `r` is secret). + +The `crypto/ipa/ipa/prover.go:113,117,122,126` sites all use this. Witness +halves a_L/a_R are secret; if the adversary can collect ~10^4 IPA proofs and +average traces (real attack budget for a TEE-resident prover), key recovery +becomes plausible. The `prover_blinding_test.go:149-195` "TestTimingVariance" +test only measures macroscopic timing variance, not microarchitectural side +channels — it cannot detect this. + +Fix hint: route through a constant-time MSM (e.g., regular wNAF with fixed +window, no precomputed-table lookups indexed by secret bits), or move the +prover into a CPU enclave with strict cache partitioning. The blinding helps +but does not close the channel; documenting it as "the trace observed by an +attacker depends on (k_i · r) where r is fresh per call" is true but not +sufficient — that's where the trace ENDS UP, not where the SECRET STARTS. + +### N5 — [HIGH] `bn254` Metal `g1_to_affine` and `g1_double` retain secret-dependent branches; the constant-time guarantee is partial + +`luxcpp/crypto/bn254/gpu/metal/bn254.metal:284-303` `g1_to_affine` has +`if (fp256_is_zero(p.z)) { ...return...; }` — secret-dependent control flow +on the Z coordinate. `g1_double` at `bn254.metal:306-309` does the same: +`if (fp256_is_zero(p.z)) return p;`. `pt_cmov` is correctly applied to the +add/scalar-mul dispatch (lines 335-415) — that's the win advertised in #192. +But `g1_double` is called from the very first iteration of `g1_scalar_mul` +and on every base doubling at line 411, AND `g1_to_affine` is called on the +public output (line 468, 507, 544). + +For the scalar-mul body: `g1_double(base)` is ALWAYS called regardless of +the bit; `pt_cmov(acc, sum, mask)` selects whether to take the add. If the +running base is the identity at any point during the ladder (it can't on +non-zero scalars, but the analysis must hold for all inputs), `g1_double`'s +early-exit branches. For `g1_to_affine` on the public output, the public +result CAN be the identity (Pedersen commit of zero with zero blinding = +identity); the branch reveals "result was identity" via timing. That's a +correctness fact about the input, not the secret blinding — but it leaks +"was the secret the all-zero vector" which is a non-zero advantage. + +Worse: the audit claim in #192 says "constant-time properties hold AT THE +METAL ASSEMBLY level". I can't read MSL→AIR→Apple-GPU-ISA from this audit +session without a Metal toolchain, but I CAN read the source. The MSL source +has at least 4 secret-dependent branches that the compiler is free to lower +to predicated mov OR conditional branch depending on optimizer heuristics. A +timing-stable claim at the GPU-ISA level requires a disassembly check +(`metal-objdump --disassemble`), and I see no CI evidence of that. + +Fix hint: replace `if (fp256_is_zero(p.z)) ... return ...` in `g1_double` +and `g1_to_affine` with `pt_cmov`-driven masked output. For Pedersen the +output may be identity; document that and ensure the verify path doesn't +branch on it. Add a `metal-objdump` step to CI that asserts no `cmpsel.cond` +or branch on register holding `p.z` limbs. + +## Top 5 NEW design weaknesses + +### D1 — [HIGH] CompositeAttestation interface vs envelope is a dual-type problem + +The release gate consumes a `CompositeAttestation` *interface* +(`pkg/kms/release.go:59`) and the wire layer produces a `CompositeAttestation` +*struct* (`pkg/attestation/composite.go:134`). Different files, same name, +unrelated method sets. A fix for N1 must NOT just swap types — the wire +struct doesn't have `Verify(nonce)`/`TEEPublicKey()`, and the gate interface +doesn't have `VerifyEvidence`. This invites a future regression where +someone "implements both" and gets the worst of both. + +Fix: collapse to one type. The wire struct should grow `VerifyAndPolicy(ctx, +nonce, policy) (*VerifiedRelease, error)` and the gate should consume that. + +### D2 — [HIGH] `require_*` flags advertised but missing from Go side + +LP-137.md §2.7:312-315 claims "explicit `require_sev_snp`, `require_tdx`, +`require_nv_nras` booleans on the `CompositeAttestationConfig` struct. Zero- +byte fields no longer wildcard." Searching across `lux/*.go` for any of +`require_sev_snp`, `require_tdx`, `require_nv_nras`, `RequireSEVSNP`, +`RequireTDX`, `RequireNVNRAS` returns zero matches. The field names exist +only in C++ headers. The Go release-policy struct +(`pkg/kms/release.go:85-103`) has only `RequiredRIM` and `AllowedHardware` +maps — no per-issuer-kind require booleans. O5 closure is C++ only; +Go side is unchanged. + +### D3 — [MEDIUM] WGSL Miller loop is deferred but advertised as shipped + +`luxcpp/crypto/bn254/gpu/wgsl/bn254.wgsl:797-804` explicitly says +"k_miller_iter and k_pairing on WGSL: deferred. The full Miller loop on WGSL +with u64 emulation is ~2 KLOC and exceeds the per-session budget for this +commit. The host-driver fallback path runs the CPU oracle so the determinism +harness still asserts byte-equality of cyclotomic-square^100 / e(P,Q) +against the CPU oracle, exercising the wire format end-to-end." + +The CHANGELOG narrative for #228 (the WGSL Miller) implies it shipped. It +did not. The "byte-equality" the harness checks is CPU-vs-CPU because the +WGSL fallback IS the CPU oracle. This is the exact O1/O3 violation LP-137 +§1 calls out as the worst-case oracle bypass. + +### D4 — [MEDIUM] `SetBytesLE` mutates caller's buffer + +`crypto/ipa/bandersnatch/fr/element.go:732-748` reverses `e` in place. Any +caller that retains a reference to the bytes after passing them to +`SetBytesLE` gets a corrupted buffer. The transcript usage at +`common/transcript.go:76` happens to be safe (Sum returns a fresh slice), +but `common/common.go:46` (`SetBytesLECanonical(x)` where `x` is a 32-byte +read buffer) silently corrupts a buffer the caller may want to log/audit. +A future caller that passes a slice into a `[32]byte` array's underlying +storage will get a heisenbug. + +Fix hint: copy then reverse, or write a new endian-flip-and-set primitive +that doesn't mutate. + +### D5 — [MEDIUM] Re-publication CHANGELOG conflates implementation date with provenance + +`luxcpp/crypto/CHANGELOG.md:5` "All work was completed by 2025-12-25, then +re-published in April 2026 from memory and audit recovery after a laptop- +theft data-loss event. Commit timestamps reflect the re-publication; this +changelog reflects the actual implementation order." + +Cryptographically material: a reviewer reading commit hashes +`43aae365adf1f84dab00d55f26d9a6b49777f889` (line 13) and matching them to +the December 2025 narrative at line 9 cannot verify the claim — no signed +manifest of pre-theft tree hashes, no PGP-signed witness from a third party. +This narrative is a trust assertion, not a verification. For a spec that +*relies* on byte-equality KAT vectors being adversarially generated, the +"recovered from memory" provenance is a yellow flag: were the December +KATs fabricated post-hoc to match the recovered code? No way to tell. + +Fix hint: stop conflating. Either (a) say "the work was completed in April +2026" and accept the late date, or (b) attest the December timeline with a +notarized manifest of pre-theft commit hashes, even if the trees are gone. +Half-claims weaken both. + +## Top 5 NEW oracle bypasses + +### O-N1 — [HIGH] Pedersen Metal kernel comparison is host-supplied G,H, not derived from DST + +`bn254.metal:438-463` accepts G,H as host-supplied 8-limb buffers +(buffer(2)/buffer(3)). The kernel cannot independently verify these were +derived from the DST. An adversary with host code-injection authority can +supply G,H with a known discrete-log relation; the kernel computes a valid +commitment that no longer hides. The "fix" in #192 ("Host MUST derive G,H +independently via bn254 hash-to-curve with brand-neutral DSTs") is a +README-level constraint, not a kernel-level invariant. The KAT harness +cannot detect host-side DST substitution because the harness IS the host. + +### O-N2 — [HIGH] WGSL pairing self-comparison + +See D3. Byte-equality test for `e(P,Q)` and `cyclotomic_sqr^100` on WGSL is +CPU-against-CPU. Any CPU pairing bug passes silently. Adversary writes any +P,Q producing a CPU bug → KAT generates new "expected" → test passes → +production GPU runs CPU fallback → bug ships. + +### O-N3 — [MEDIUM] Second-oracle KAT for bn254/banderwagon does not cover Miller / pairing + +LP-137 §317-322 advertises `kat-second-oracle-2026-04-28` with arkworks +cross-verification for bn254 + banderwagon. I confirmed bn254 has CUDA +final-exp via Fuentes-Castaneda (`bn254_pairing.cuh:811`) and CPU at +`bn254_pairing.cpp:581`. I see no second-oracle KAT for the pairing path +itself — only the CPU implements Miller, and gnark/arkworks both have +shared upstream lineage in lots of curve code. This is the "same family" +failure LP-137 §1 is built to prevent. The CHANGELOG narrative does not +distinguish what the second oracle covers. + +### O-N4 — [MEDIUM] NRAS JWS dispatch enforces alg×key but allows ES256K substitution silently + +`mpc/pkg/attestation/nvidia/nras_client.go:319-387`: dispatch covers +`EdDSA`, `ES256`, `ES384`, `PS256`, `PS384`, `none`, default. NOT covered: +`ES256K` (secp256k1), `RS256` (RSASSA-PKCS1-v1_5), `EdDSA` over Ed448. +An NRAS server (or MITM with a forged trust root upload) presenting +`alg=ES256K` with a secp256k1 trust root falls into `default → ErrUnknownAlg` +— good for that case. But `RS256` falls into `default` too, yet RFC 7518 +§3.1 mandates RS256 as widely-deployed; refusing it might break +compatibility AND the dispatch comment claims comprehensive defense. It's +either complete (then the comment is correct) or it isn't (then the comment +is misleading). Audit for which. + +### O-N5 — [MEDIUM] NRAS nonce comparison double-negates and allows non-32-byte non-error path + +`nras_client.go:204-207`: +``` +jn, derr := hex.DecodeString(strings.TrimPrefix(jwtClaims.Nonce, "0x")) +if derr != nil || len(jn) != 32 || sha256BytesEqual(jn, nonce[:]) == false { + return nil, ErrNRASNonceMismatch +} +``` + +If `jwtClaims.Nonce == ""` (empty) the outer guard at `:203` skips entirely — +no nonce binding enforced. NRAS server can omit the nonce claim and the gate +proceeds. The defense relies on "NRAS will always include nonce" which is a +trust-the-issuer assumption. Combined with N1 (release gate doesn't call +this code path anyway) the practical exploit is moot, but conceptually the +empty-nonce silent-skip is a bypass. + +Fix: require non-empty `jwtClaims.Nonce` when the request supplied one; +empty token nonce → `ErrNRASNonceMismatch`. + +## Status of prior audit findings + +| ID | Finding | Status | Why | +|----|---------|--------|-----| +| **B1** | wrong import path `luxfi/fhe/threshold` | RESOLVED | one-line fix landed; not seen in current tree | +| **B2** | CDS noise-proof gap (`PartyKeys=nil` public-key fallback) | PARTIALLY | "real fixtures" added but the structural fallback path still requires audit; not re-tested in this round | +| **B3** | blake3 `test_vectors.json` missing | RESOLVED | not flagged by any test invocation in this session | +| **B4** | C-ABI returns `CRYPTO_ERR_NOTIMPL` while wins claimed | RESOLVED | spot-checked; concrete bodies present | +| **B5** | `lux/fhe/policy/` fabrication | OPEN-WHY | claims retracted in LP-137.md but the production caller `mpc/pkg/mpc/tfhe_session.go:154` still routes through `tfhe.NewKeyGenerator` whose `guardUnsafe()` panics.

A +worker reporting "TEE: yes" tells the dispatcher nothing about whether +the GPU bounce buffer is encrypted, whether the NVSwitch fabric is +attested, or whether the operator could swap the firmware out from +under us. A workload tagged "private" tells the dispatcher nothing +about whether the user data is confidential, the model weights are +confidential, the order flow is regulated, or the validator-key +material is being touched. + +The fix is to encode both sides of the question as small, totally-ordered +enums: + +- `ComputeTrustMode` = a five-step ladder from + `PublicDeterministic` to `ZKOrFraudProofed`. +- `ConfidentialIOLevel` = a five-step ladder from `None` to + `FullDeviceIOAttested` (covering CPU TEE, GPU TEE, protected PCIe, + and full attested device IO including NVSwitch + DPU NIC). +- `WorkloadPrivacyClass` = a six-tag classification from `Public` to + `ResearchContribution`. + +`Eligible()` becomes a conjunction of integer comparisons and set +memberships against these enums. The truth table is small enough to +audit by inspection and large enough to cover every gate the runtime +needs. + +The composite attestation envelope is necessary because no single +attestation report covers the whole platform. NVIDIA NRAS attests the +GPU; Intel TDX / AMD SEV-SNP attests the CPU; UEFI / kernel +measurements attest the firmware path. The verifier must observe all of +them together to make a sound trust decision. Per the NVIDIA +Confidential Compute and Intel Trust Authority reference docs, the +right encoding is a deterministic, canonically-ordered envelope whose +digest is the durable identity of the platform state.

The same envelope produces the same root on every node, every +run. The root is what `WorkerCapability.AttestationRoot` stores and what +the verifier re-derives independently. + +`Root()` does not verify the evidence. Verification — checking the +NVIDIA NRAS signature, the AMD SEV-SNP attestation report, the Intel +Trust Authority verdict — is the consumer's job and lives in a +verifier-specific package keyed on `Evidence.Issuer`. + +`Validate()` enforces: + +- envelope `Version` matches `EnvelopeVersion` +- `WorkerIDs` are non-empty, prefix-correct, sorted ascending, + duplicate-free +- enums are `Valid()` +- at least one evidence entry exists +- every evidence entry has a non-empty Kind / Issuer / SubjectID / Blob + and a non-zero `IssuedAt` +- composite trust mode (`>= TrustCpuGpuCompositeTEE`) requires at least + one GPU evidence entry (`EvidenceGPUNRASReport` or + `EvidenceGPUVendorReport`) +- envelope `IssuedAt` is non-zero + +### 5. Cross-language byte stability + +Every enum has a C++ mirror at +`luxcpp/lattice/include/lux/lattice/types/trust.hpp`: + +```cpp +enum class ComputeTrustMode : std::uint8_t { ... }; +enum class ConfidentialIOLevel : std::uint8_t { ... }; +enum class WorkloadPrivacyClass : std::uint8_t { ... }; + +static_assert(sizeof(ComputeTrustMode) == 1, ""); +static_assert(sizeof(ConfidentialIOLevel) == 1, ""); +static_assert(sizeof(WorkloadPrivacyClass) == 1, ""); +static_assert(static_cast(ComputeTrustMode::ConfidentialIO) == 3, ""); +// ... full integer-value pinning for all 14 variants +``` + +The matching C++ test +(`luxcpp/lattice/test/trust_test.cpp`) runs 41 `CHECK` assertions +covering size, ordering, validity predicates, and a 4-byte +`TrustTriple` byte-image round-trip. The Go-side test +(`luxfi/lattice/v7/types/trust_test.go::TestTrustEnum_CrossLangByteImage`) +asserts the same 4-byte image. If either side changes enum width or +integer encoding, both tests fail and the cgo boundary stops corrupting +silently. + +`WorkerCapability`, `NodeCapability`, `LanePolicy`, `WorkloadPolicy`, +and `CompositeAttestation` are not byte-stable structs — they cross +language boundaries via deterministic CBOR (envelope) or JSON-over-RPC +(registry), so per-field offset stability is not required and not +asserted. The enums embedded in those structs *are* byte-stable, which +is what the cgo dispatch path actually consumes. + +### 6. Determinism contract + +`Root()` produces the same bytes for the same envelope on every machine +because: + +- `fxamacker/cbor.CoreDetEncOptions()` enforces: + - shortest-form integer encoding + - CTAP2 canonical map key ordering (bytewise lexical of the encoded + keys) + - definite-length encoding only + - no indefinite-length strings or arrays + - finite-only floats +- `IssuedAt` is forced to UTC inside `Root()` so timezone-tagged inputs + do not change the digest. +- `WorkerIDs` are caller-sorted and duplicate-free; out-of-order input + is rejected at validate time, not silently re-sorted. +- `Evidence` order is preserved (not re-sorted) because measurement + logs and verifier outputs may carry ordering semantics. + +The combination is RFC 8949 §4.2 conformant. Any conforming CBOR decoder +on any platform reads the same envelope; any conforming encoder +re-encodes the same body to the same bytes. + +## Rationale + +### Why a separate trust ladder and IO ladder? + +Trust mode answers "who can I run on?". IO level answers "how do bytes +move on that worker?". Hopper Confidential Compute pairs a GPU TEE +(trust) with a bounce-buffer-encrypted PCIe path (IO); Blackwell adds +TEE-IO (a strictly stronger IO posture without changing the trust +posture). Collapsing the two into one enum forces every downstream +consumer to re-derive whether their gate is about isolation or about +data movement. Two ladders, one comparison each, twelve gates total. + +### Why CBOR for the attestation envelope? + +LP-137-FHE-TYPING uses raw `encoding/binary` for fixed-shape structs +because the math kernels need byte-for-byte layout stability across +cgo. The attestation envelope is shaped differently: variable-length +evidence blobs, vendor-specific issuers, optional fields that some +verifiers populate and others skip. RFC 8949 §4.2 deterministic CBOR +gives a canonical wire form for variable-shape data with stable digests. + +`fxamacker/cbor` is already a direct dependency in `luxfi/mpc` for +intent canonicalization, FROST/LSS/BLS config marshalers, and +SR25519 key shares (see `pkg/intent/canonical.go`, +`pkg/mpc/frost_config_marshal.go`, etc.). One library, one canonical +encoding, no new dependency. NVIDIA NRAS and Intel Trust Authority +both publish CBOR-shaped composite envelopes; matching their on-the-wire +format reduces verifier impedance to zero. + +### Why does `Root()` reject invalid envelopes? + +A digest over an invalid envelope is a silent-corruption hazard: the +hash succeeds, but no two implementations would agree on what the +hashed bytes meant. Forcing `Root()` to validate makes "I have a root" +imply "I have a well-formed envelope". The verifier still re-validates +on its end; the producer-side check exists to catch the bug before it +ships. + +### Why is `Eligible()` order-sensitive? + +The returned sentinel error labels the metric exported by the scheduler +(`ineligible_reason{lane,workload,error_class}`). If the order of gates +shifted, an operator chasing "lane_trust_below_floor" alerts could +suddenly see them disappear because gate 4 (lane backend) now fires +first. The fixed order, regression-pinned by `TestEligible_GateOrdering`, +keeps the dashboard stable. + +### Why does the privacy-class gate (#12) re-check what `WorkerCapability.Validate` already checks? + +`Eligible()` is on the scheduler hot path; `Validate()` is on the API +edge. A worker record that bypassed the API edge (e.g. read directly +from a stale cache after a downgrade) would fail at gate 12 even though +its struct is still locally consistent. The redundancy is cheap (one +arch-enum compare) and closes the trust-on-trust hole. + +## Backwards compatibility + +This LP introduces three new packages (`luxfi/mpc/pkg/registry`, +`luxfi/mpc/pkg/attestation`) and a new C++ header +(`luxcpp/lattice/include/lux/lattice/types/trust.hpp`).

Per-algorithm formal specs live in their own LPs (LP-026, LP-029, LP-066, LP-069, LP-070--077, LP-110--126, LP-131, LP-146--159). LP-137 carries no per-algorithm content. + +## Abstract + +A GPU-native crypto substrate for the 9-chain Lux topology. Every primitive +ships a first-party CPU canonical (Go reference) and first-party +Metal/CUDA/WGSL kernels, all byte-equal to the same ground truth. Audited +upstreams (blst, c-kzg-4844, gnark-crypto, PQClean) appear only as test +oracles — never linked into shipped libraries — so the byte-equality test +retains its adversarial-distance property: a bug on either side fails the +test. + +The stack covers 29 algorithms across hashes, AEAD, EC + pairings, post- +quantum signatures, lattice primitives, FHE building blocks, threshold +schemes, and composite remote-attestation parsers. It satisfies the +**GPU-residency invariant**: no chain-local hot path leaves attested GPU +memory in production. CPU touches reality only at packet ingress, cold-state +page service, attestation handshake, and watchdog. + +## 1. Motivation + +A fragmented crypto substrate makes the byte-equivalence contract impossible +to enforce. Three failure modes that LP-137 closes: + +1. **Oracle bypass.** When CPU and test oracle come from the same upstream + family (e.g. both from blst or both from gnark-crypto), the byte-equality + test loses its adversarial-distance: an upstream bug passes through both + sides. First-party CPU + audited test oracle is the correct adversarial + structure — bug on either side fails the test. +2. **Vendor symbol leak.** Production binaries linking blst / mcl / + BoringSSL into the production graph re-expose vendor branding and tie + the security boundary to upstream release cycles. LP-137 pins those + libraries to test-only oracles at `/test/cmake/`. +3. **Brand fragmentation.** Per-org symbol prefixes (`LUX_*`, + `LUXFI_*`, `HANZO_*`) make the same algorithm look like five + different libraries. Algorithm names ARE the namespace. + +## 2.

No seat needed. + +This gives bounded consensus cost (always N validators) with unbounded +economic participation (delegation) and unbounded service capacity +(replicas). + +## Motivation + +Fully permissionless validator sets (Ethereum-style) have two problems: + +1. **Unbounded consensus cost** — more validators means more signatures, + more gossip, more state to track. +2. **Validator quality drift** — low barrier to entry attracts unreliable + operators. + +Fully permissioned sets (old Diem, early Cosmos Hub) solve those but lose: + +1. **Economic openness** — ordinary users can't contribute capital. +2. **Service scaling** — only the N validators can serve data, limiting + RPC/archival throughput. + +The three-tier design captures the bounded-consensus benefit while +preserving open economic participation and horizontal service scaling. + +## Tier 1: Validator seats + +### Seat as X-Chain native NFT + +No ERC-721 contract. The seat is a native X-Chain asset defined at genesis: + +``` +Genesis asset: SEAT + Name: LuxValidatorSeat + Symbol: LVS + Denomination: 0 (indivisible, NFT-like) + FixedCap: true + InitialSupply: N (default 100) + Mint: disabled after genesis (fixed supply) + OutputType: NFTTransferOutput (each unit has a unique token ID) +``` + +Each of the N seats is a distinct UTXO holding 1 × SEAT with a unique +token ID (0 to N-1). Transfers are standard X-Chain `BaseTx` consuming and +producing `NFTTransferOutput`s. No EVM, no contract. + +Seats are: + +- **Transferable** on X-Chain like any native asset, subject to the stake + lock (NFT is locked while its holder is an active validator + unbonding + period of 21 days). +- **Issued** at genesis (initial 100 seats) to vetted operators. Governance + can expand N via supermajority vote (P-Chain governance tx mints + additional SEAT NFTs). +- **Slashable** — misbehavior slashes the self-bond LUX; seats can also + be forfeited by governance vote (NFT burned and reissued). + +### Registration + +Validators register on P-Chain by atomically importing their SEAT from +X-Chain and posting a self-bond: + +```go +AddPermissionedValidatorTx { + NodeID ids.NodeID + SeatImport *atomic.Input // X-Chain UTXO containing 1 × SEAT + SelfBond []*lux.TransferableInput // ≥ min_bond × LUX + CommissionBps uint16 + MLDSAPubKey []byte + BLSPubKey []byte // both keys for PQ upgrade path + VRFKey []byte + Endpoints []Endpoint + Duration uint64 // seconds; max 1 year per registration +} +``` + +P-Chain verifies: + +1. The imported UTXO contains exactly 1 × SEAT with a token ID not currently + bound to an active validator. +2. Self-bond is at least `min_bond` LUX. +3. Public keys are well-formed. +4. The signer controls both the imported UTXO and the self-bond inputs. + +On success, the SEAT + self-bond are locked in a stake output on P-Chain +until the registration expires. At expiry (or via `StopValidatorTx`), the +SEAT is exported back to X-Chain and the LUX self-bond (minus any slashing) +is returned. + +### Delegation + +Delegators send LUX only — no SEAT required: + +```go +AddDelegatorTx { + NodeID ids.NodeID // which validator to back + LuxStake []*lux.TransferableInput // ≥ 10 LUX minimum + Duration uint64 +} +``` + +The delegated stake is locked for the delegation duration + unbonding +period. Delegators share the validator's block and signing rewards minus +the validator's published commission rate. + +### Revocation + +Seats can be revoked for: + +- Double-signing (automatic, 100% of self-bond slashed) +- Persistent liveness failure > 14 days (governance vote) +- Criminal/regulatory action against holder (governance vote) + +A revoked seat returns to the NFT pool for re-issuance. + +## Tier 2: Open delegation + +### Delegation + +Anyone holding LUX can delegate to any active validator: + +```go +Delegation { + Delegator common.Address + ValidatorSeat uint256 + Amount uint64 + StartTime uint64 +} +``` + +Delegated LUX is locked for the duration of the delegation plus the +unbonding period. Delegators receive: + +``` +delegator_reward = (1 - commissionBps/10000) * share_of_validator_reward +validator_reward = commissionBps/10000 * delegator_reward + self_bond_share +``` + +### Slashing proportionality + +When a validator is slashed, the slash hits: + +1. Self-bond first (up to 100% of offense penalty) +2. Delegated stake proportionally (if self-bond insufficient) + +This ensures validators eat their own risk first, then delegators share +residual penalty. + +### Unbonding + +Delegators can initiate unbonding at any time. Funds become liquid after +the unbonding period (default 21 days) during which they remain slashable +for offenses committed during the bond period. + +## Tier 3: Read-only replicas + +### What a replica does + +A read-only replica: + +- Connects to the Lux P2P network +- Downloads blocks and Quasar certs +- Verifies certs (ML-DSA sigs + Ringtail aggregates + Z-chain ZK proofs) +- Executes transactions to compute state +- Serves RPC to clients +- Optionally serves archival history, light-client proofs, bridge proofs + +What it does NOT do: + +- Sign blocks +- Participate in consensus votes +- Hold a validator seat +- Receive direct block rewards + +### Why this scales + +| Load class | Validator node | Read-only replica | +|-----------|---------------|-------------------| +| Signing | required | no | +| State verification | required | required | +| State storage | required | optional (pruning allowed) | +| RPC serving | optional | primary role | +| Archival | optional | primary role | +| Light-client proofs | optional | primary role | +| Bridge relayer | optional | primary role | + +The 100 validator nodes handle a fixed consensus workload.

Replaces `k` independent Miller-loop dispatches plus a separate Fp12 product reduction with a single kernel that interleaves all `k` pairs through one shared 64-step ate loop and accumulates `f_k = ∏ f_i` line-by-line. Eliminates `k − 1` Fp12 multiplications per batch and reduces dispatch overhead from `k + 1` round-trips to `1`. Measured uplift on Apple M1 Max for `k = 1024` (BridgeVM batched real pairing): **9.5×** mean (LP-137 §2.3).

The `f` updates are serial within a bit (one Fp12 chain) but the **same** Fp12 chain that the unfused version would do at the very end — net savings: `k − 1` extra Fp12-mul-by-Fp12 operations are eliminated, replaced by `k` Fp12-mul-by-sparse-line operations (~6× cheaper each). + +### Determinism + +Line accumulation order is fixed: `j = 0` first, ascending. Squaring is the same per-bit canonical squaring as single-pair Miller. Final exponentiation runs once on the combined `f`. CPU/Metal/CUDA/WGSL produce byte-equal Fp12 output; the byte-equality test runs with `k ∈ {1, 2, 4, 8, 16, 64, 256, 1024}` × `100` random `(P, Q)` batches. + +### Performance + +| `k` | Prior (per-pair Miller + product) | LP-162 fused | Source | +|---:|---|---|---| +| 1024 | 99 040 ms | 10 425 ms (9.50×) | BridgeVM v0.60 measured, n=1024 mean (LP-137 §2.3) | + +The `k = 1024` row is the only row backed by a number on this host.

The same `PaymentOffer` / `PaymentProof` data model serves four transport layers: + +1. **HTTP/402 — discovery.** Compatible with the x402 spec; any HTTP route can demand payment by returning an `accepts[]` envelope and accepting an `X-PAYMENT` header on retry. +2. **ZAP wire (LP-022) — high-volume A2A.** Zero-allocation binary frames for agents on the same Lux subnet exchanging offers and proofs at line rate. +3. **On-chain escrow — settlement.** A trustless `AgentEscrow` contract with timeout, challenge period, and mutual cancel. +4. **Streaming sessions (LP-047) — continuous flow.** Per-second token streams for long-running work, vesting, or subscription flows, with mid-stream upgrade to multi-party (MPP) sessions. + +Compliance, identity, and threshold-signing slot in via existing Lux primitives — LP-088 (compliance hooks), LP-001 (security tokens), LP-019 (threshold MPC). Replay protection, expiry, and currency selection are normative parts of the wire format. The reference implementation is [kcolbchain/switchboard](https://github.com/kcolbchain/switchboard). + +## Motivation + +Every AI agent that wants to call a paid API or hire another agent today rolls its own payment plumbing: bespoke JSON over HTTP, Stripe meters, custom RPC paywalls, ad-hoc ETH transfers. That works for one app. It collapses the moment two agents from different teams need to settle on the fly. + +Three rails exist in the wild but none compose: + +| Rail | Strength | Gap | +|---|---|---| +| Coinbase x402 | HTTP-native, agent-friendly | no on-chain escrow, no streaming, no MPP, no compliance hook | +| Sablier / token streaming | continuous flow | no HTTP discovery, no per-call quote | +| Raw on-chain transfer | trustless settlement | no negotiation, no agent identity, no quote envelope | + +LP-167 is the union: a single `PaymentOffer` data type that any of the four transports can carry, on top of Lux's existing crypto and securities primitives.

PaymentProof + +A `PaymentProof` is a signed receipt produced by the payer after settlement. + +``` +PaymentProof { + chain_id: u64 + timestamp: u64 // unix seconds + payer: [20]byte + tx_hash: [32]byte // settlement tx (or escrow create tx for escrow scheme) + amount: [32]byte // uint256 big-endian, MUST match offer + nonce: string // MUST match offer.nonce +} +``` + +ZAP wire encoding uses message type `0x71`.

HTTP/402 Discovery Envelope + +A server gates a route by returning HTTP 402 with the body: + +```json +{ + "x402Version": 1, + "accepts": [ + { + "scheme": "exact", + "network": "lux-c", + "maxAmountRequired": "1000", + "asset": "0x036CbD53842c5426634e7929541eC2318f3dCF7e", + "payTo": "0x...", + "resource": "https://example/v1/infer", + "description": "model inference, 1k tokens", + "mimeType": "application/json", + "expiresAt": 1714521600 + } + ] +} +``` + +Headers: + +| Header | Direction | Required | Purpose | +|---|---|---|---| +| `WWW-Authenticate: x402` | response | yes | discoverability for non-LP-167 clients | +| `x402-version` | response | yes | spec version, currently `1` | +| `Accept-Payment` | request | optional | scheme preference (`exact`, `streaming`, `mpp`) | +| `X-PAYMENT` | request | yes (on retry) | base64-encoded `PaymentProof` for `exact`, or session token for `streaming`/`mpp` | + +A client that already holds a valid `PaymentProof` MAY pre-emptively include `X-PAYMENT` on the first request and skip the 402 round-trip. Servers MUST accept this. + +### 5. Schemes + +#### 5.1 EXACT + +Single-shot quote-and-settle. The payer: + +1. Receives 402 with `accepts[]`. +2. Picks an accept entry, transfers `amount` of `asset` to `payTo` on `network`. +3. Signs a `PaymentProof` referencing the tx hash. +4. Retries the request with `X-PAYMENT: base64(proof)`. + +The server verifies (a) the on-chain transfer, (b) the proof signature matches the payer of that transfer, (c) `nonce` matches the offer it issued, (d) `expiresAt` has not passed. + +#### 5.2 STREAMING + +Long-running work. Constructed as an LP-047 `Stream` plus an `OfferRef`: + +```solidity +struct OfferRef { + bytes32 offerDigest; // PaymentOfferDigest + address payee; + address payer; + uint256 streamId; // LP-047 stream +} +``` + +The payer creates an LP-047 stream from itself to the payee for the duration covering the work. The session token presented in `X-PAYMENT` is `keccak256(offerDigest || streamId)`. The server verifies the stream is live (`balance(payee) > 0`), un-canceled, and points back to its issued offer. + +Stream cancellation by the payer terminates the agent's session. The server SHOULD return 402 with a fresh offer to re-up. + +#### 5.3 MPP (Multi-Party Payments) + +A single inbound payment to a coordinator splits across N agents that contributed. Each agent presents a co-signed `PaymentOffer` whose `amount` is the agent's share and whose `recipient` is a threshold address (LP-019 / LP-076). The coordinator settles once on-chain to the threshold address; the threshold quorum signs a release transaction splitting per the agents' shares. + +``` +PaymentOffer.scheme = MPP +PaymentOffer.recipient = threshold_address (controlled by quorum of N agents) +PaymentOffer.description = "session=;split=alice:0.4,bob:0.4,carol:0.2" +``` + +Replay protection is via the `nonce` field plus the on-chain quorum's monotonically increasing `sessionCounter`. + +### 6. AgentEscrow Contract Interface + +A reference contract (`AgentEscrow.sol`) provides trustless settlement when neither side trusts the other. Spec excerpt: + +```solidity +interface IAgentEscrow { + function createPayment( + bytes32 offerDigest, + address payee, + uint256 amount, + address asset, // 0x0 for native LUX/ETH + uint64 timeoutBlocks, + uint64 challengePeriodBlocks + ) external payable returns (bytes32 requestId); + + function confirmPayment(bytes32 requestId) external; // payer releases + function requestRefund(bytes32 requestId) external; // after timeout + function cancelPayment(bytes32 requestId) external; // mutual + + event PaymentCreated(bytes32 indexed requestId, address indexed payer, address indexed payee, uint256 amount, bytes32 offerDigest); + event PaymentConfirmed(bytes32 indexed requestId); + event PaymentRefunded(bytes32 indexed requestId); +} +``` + +`offerDigest` MUST be `PaymentOfferDigest` of the original signed offer. Indexers MAY join `PaymentCreated` to off-chain offers via that digest. + +### 7. Compliance Hooks + +When `asset` is a security token (ERC-3643, LP-088), the `AgentEscrow.createPayment` and `AgentEscrow.confirmPayment` calls MUST consult `ComplianceRegistry.canTransfer(payer, payee, amount)` before holding or releasing funds. A non-zero restriction code reverts with the canonical error message from LP-088. Agent identities that hold security tokens MUST be registered in the `IdentityRegistry`. + +This is the bridge that lets a regulated workflow (security-token-denominated agent work) execute on the same protocol as commodity USDC payments. + +### 8. Threshold-Signed Offers + +For MPP and high-value flows, a `PaymentOffer` MAY be signed by a quorum of agent keys via LP-019 / LP-155 (CGGMP21 ECDSA) or LP-154 (FROST Schnorr). The signature on the wire is replaced with the threshold signature (still 65 bytes for ECDSA; 64 + 1 recovery id for Schnorr). Verification follows the curve specified in `PaymentOffer.scheme` extension byte (reserved for future use); for v1, ECDSA is implied. + +The threshold quorum SHOULD be defined by an on-chain registry (per-session) so a verifier can resolve which keys participated. + +### 9. Replay Protection + +| Field | Role | +|---|---| +| `PaymentOffer.nonce` | payee-chosen UUIDv4 or monotonic counter, scoped to (payee, endpoint) | +| `PaymentOffer.expires_at` | hard expiry | +| `PaymentProof.tx_hash` | settlement uniqueness — payer cannot reuse a proof against multiple offers | +| `AgentEscrow.requestId` | derived from `keccak256(payer, payee, nonce, block.timestamp)` | + +A server MUST reject any `PaymentProof` whose `nonce` it has already recorded as redeemed. A `PaymentProof` is one-shot. + +### 10. Cross-chain settlement + +When `PaymentOffer.chain_id` differs from the chain hosting the `AgentEscrow`, settlement MAY use LP-016 (OmnichainRouter) or LP-017 (Native Bridge Programs for Teleport). The proof's `tx_hash` MUST reference the destination-chain settlement; the server validates via Warp messaging (LP-021) or a light-client query. + +### 11. Currency selection + +`PaymentOffer.currency` is informative; `PaymentOffer.asset` is normative. Servers SHOULD list multiple `accepts[]` entries when willing to take more than one asset (e.g., USDC on Lux-C, USDT on Lux-C, native LUX). Clients pick the cheapest fit. + +`asset == 0x0` is the canonical sentinel for native chain currency. + +## Reference Implementation + +[kcolbchain/switchboard](https://github.com/kcolbchain/switchboard) — Python + Solidity, MIT. + +- `switchboard/x402_middleware.py` — server-side HTTP/402 middleware, FastAPI/Flask drop-in. +- `switchboard/zap_transport.py` — `PaymentOffer` / `PaymentProof` ZAP wire encode/decode (uses [luxfi/zap](https://github.com/luxfi/zap) `zap_py`). +- `switchboard/gas_tracker.py` + `gas_budget.py` — per-hour / per-day client-side spend caps. +- `switchboard/nonce_manager.py` — client-side nonce manager with reorg protection. +- `contracts/AgentEscrow.sol` + `src/payment_protocol.py` — on-chain escrow + Python client. +- `web/` — public side-by-side explorer for x402 / MPP / AP2 / Circle / on-chain escrow. + +The implementation has been audited internally; an external audit is expected during the LP-167 Final review phase. + +## Security Considerations + +### Replay & double-spend +Mitigated by `nonce`, `tx_hash`, `expires_at`, and the server-side proof-redemption ledger (§9). A compromised payee key can sign duplicate offers but cannot redeem the same proof twice against a compliant server. + +### Front-running +A passive observer of an unsigned `PaymentOffer` cannot front-run settlement because the proof ties to the payer's address. A passive observer of an in-flight `PaymentProof` cannot replay because the server records `nonce` redemption atomically. + +### Key compromise +A compromised payer key allows arbitrary spend up to its balance — this is unavoidable for hot-wallet agents. Mitigation: use the gas-budget tracker (`switchboard.gas_budget`) to cap per-hour and per-day burn before submission, and prefer threshold-signed offers for high-value flows. + +### Long-lived offers +An offer with a far-future `expires_at` is an open option for the payer. Servers SHOULD set short expiries (~5 minutes for `EXACT`, session-bounded for `STREAMING`). Clients that hold long-lived offers SHOULD treat them as bearer instruments and protect them accordingly. + +### Compliance bypass +Settlement of a security-token offer that skips `ComplianceRegistry.canTransfer` is a normative violation. Implementations MUST treat compliance failures as a hard error, not a warning. + +### MPP collusion +A subset of MPP participants colluding to claim a larger share than agreed is bounded by the threshold-quorum requirement.

The `luxgpu` org is reserved for future C++/CUDA kernel split but currently holds one stale repo. **Action:** archive `luxgpu/gpu`, retain `luxgpu` org as namespace. + +2. **luxcpp contains zero Go code** — verified. Each repo is C++/CMake. luxcpp is purely C++ canonical; no Go imports it directly. Go calls it via cgo from `luxfi/gpu` or `luxfi/crypto/c-abi/`. + +3. **Forks under luxcpp not linked into prod** — verified for `pqclean` (test-only static lib, lines 110-128). `intx`/`evmmax` are header-only deps for `bn254`/`modexp` only — not standalone forks. `blst` and `blake3-reference` are KAT oracles. **Pattern OK.** + +4. **luxfi/zapdb internal contract holds** — `luxfi/database v1.18.1` is the public API. zapdb (`v20.07.0`) is a date-stamped tag, indicating internal-only versioning. No external repo imports zapdb directly per existing audit. + +5. **luxfi/coreth tag `with-avalanchego-test-pkg`** — non-semver branch tag, suggests an in-flight migration. **Action:** cut a `v0.x.y` semver tag. + +6. **luxfi/exchange tag `web/5.141.0`** — monorepo with prefix tags (web/, api/).

The Lux organization maintains brand-neutral forks of both projects under the `luxfi` GitHub organization that track upstream semver releases without divergence in core interfaces. Jurisdiction-specific behavior (US, EU, UK, Luxembourg, etc.) is delivered as overlay compliance modules layered on top of unmodified T-REX core; the underlying token contracts remain bytecode-compatible with the broader ERC-3643 ecosystem. + +This LP supersedes nothing — it formalizes the upstream-tracking commitment already implicit in LP-001 and LP-088. + +## §1 — Rationale + +### Why ERC-3643 + ONCHAINID, not a Lux-native standard + +1. **Regulatory recognition.** ERC-3643 is the only ERC standard with measurable institutional adoption among issuers, transfer agents, and registered ATSs. Replacing it with a Lux-native standard would orphan every existing issuer and force re-onboarding of every regulated counterparty. +2. **Tooling parity.** Wallets, indexers, custody providers, and compliance vendors already integrate ERC-3643 + ONCHAINID. Drift from the standard breaks integrations and inverts the cost curve in our favor only if Lux has measurably more users than the rest of the ecosystem combined — which it does not. +3. **Audit surface.** ERC-3643 has years of public audit history. A Lux-native rewrite restarts that surface from zero. Building on audited primitives is the lowest-risk path. +4. **Identity portability.** ONCHAINID is the de-facto cross-chain identity primitive for tokenized securities. Holders carry one identity contract across every chain their issuer supports. + +### Why fork instead of consume directly + +- **Supply-chain integrity.** A pinned `luxfi/onchain-id` and `luxfi/erc-3643` fork removes upstream-availability risk during Lux release cycles. If `ERC-3643/ERC-3643` is renamed, archived, or deleted, Lux deployments do not regress. +- **Reproducible builds.** Lux's CI must build deterministically from a SHA owned by the Lux organization. Public mirrors are a SHA we control. +- **No code drift.** The forks must remain bytecode-equivalent to upstream tags. Any Lux-specific behavior is an *additive* contract that consumes the standard interfaces, not a modification of them. + +## §2 — Compatible-with-Tokeny Commitment + +### Canonical fork mapping + +| Upstream | License | Lux fork | Tracking policy | +|---|---|---|---| +| `onchain-id/solidity` | GPL-3.0 | `luxfi/onchain-id` | Track `main` + every release tag within 7 days | +| `ERC-3643/ERC-3643` | GPL-3.0 | `luxfi/erc-3643` | Track `main` + every release tag within 7 days | + +### Pinned upstream state at adoption (2026-04-28) + +| Repository | Tag | SHA | +|---|---|---| +| `onchain-id/solidity` | `2.2.2-beta3` | `0e681fbf40f7982be5f76f3bbb1f2995e28e40f8` | +| `ERC-3643/ERC-3643` | `4.1.3` | `b6c5fabf86e733ede017fef754d59eeb8f80e3f4` | + +### Hard rules + +1. **No interface drift.** The Solidity interfaces (`IIdentity`, `IClaimIssuer`, `IToken`, `IIdentityRegistry`, `IModularCompliance`, `IClaimTopicsRegistry`, `ITrustedIssuersRegistry`, `IAgentRole`) are the upstream definitions, byte-for-byte. Lux MUST NOT add, remove, or rename functions on these interfaces. +2. **No `LUX_` prefixes in Solidity identifiers.** Lux-specific code lives in additional contracts in additional files; it does not pollute the canonical namespace. +3. **License preservation.** GPL-3.0 is preserved on every fork. NOTICE / LICENSE files from upstream are retained verbatim. Each fork carries `LUXFI-FORK.md` documenting the pinned upstream SHA, the tracking policy, and the absence of core changes. +4. **Semver alignment.** Lux fork tags equal upstream tags 1:1 (e.g., `luxfi/erc-3643:v4.1.3` ↔ `ERC-3643/ERC-3643:v4.1.3`). No private versions. +5. **No backports.** If a fix exists upstream and is not released, Lux waits for the upstream release. Lux does not patch ahead. +6. **One-way contributions.** Material fixes Lux discovers go upstream as PRs to `ERC-3643/ERC-3643` or `onchain-id/solidity`. Lux does not maintain private forks of public security fixes. + +## §3 — Per-Jurisdiction Overlay (Overlay-Only) + +Jurisdiction enforcement is a composition of upstream `IModularCompliance` modules. The T-REX core token contract is unmodified; jurisdictions are added by `addModule(address)`. + +### Module taxonomy + +| Module | Jurisdiction | Enforces | +|---|---|---| +| `RegDComplianceModule` | US | Reg D 506(b)/506(c): accredited-investor claim, 12-month holding period, Form D filing flag | +| `RegSComplianceModule` | US (offshore) | Reg S Category 1/2/3: distribution-compliance period, US-person exclusion, Category-2 resale restrictions | +| `RegAComplianceModule` | US | Reg A+ Tier 1/Tier 2: state blue-sky filings, $75M Tier-2 cap, non-accredited per-investor limits | +| `RegCFComplianceModule` | US | Reg CF: $5M annual cap, per-investor limits computed from `IClaimIssuer` income/net-worth claims | +| `MiCAComplianceModule` | EU | MiCA asset-referenced/e-money tokens: whitepaper hash, issuer authorization claim, ESMA reporting hook | +| `FCAComplianceModule` | UK | FCA permission claim, UK-resident vs non-resident transfer rules, financial-promotion gate | +| `CSSFComplianceModule` | Luxembourg | CSSF authorization, AIF/UCITS classification, RAIF eligibility | +| `IOMComplianceModule` | Isle of Man | IOMFSA authorization, Class 3/Class 4 distinction | + +### Composition rules + +- A SecurityToken MAY install N compliance modules. All modules MUST return `true` from `moduleCheck` for the transfer to succeed. +- Modules MUST be stateless beyond their own storage. Cross-module dependencies are forbidden — each module is independently auditable. +- A jurisdiction module MUST consume only canonical ONCHAINID claims. Adding a non-standard claim topic requires registering it via `IClaimTopicsRegistry`; it does not justify forking ONCHAINID. +- Modules MUST be upgradeable through the upstream `IModularCompliance` upgrade pattern. Lux does not introduce a competing upgrade mechanism. + +### Trusted issuer scope + +Each jurisdiction defines an allowlist of `IClaimIssuer` contracts whose claims it accepts (e.g., a CSSF-licensed KYC provider for Luxembourg). The allowlist lives in `ITrustedIssuersRegistry` exactly as upstream specifies. Lux does not maintain a parallel registry. + +### Implementation location + +Overlay modules ship as a separate Lux package — out of scope for this LP. They depend on `luxfi/erc-3643` and `luxfi/onchain-id` as Solidity-package imports, never as forks. + +## §4 — Migration Guide for Existing Lux Fund 2022 ERC-3643 Holders + +The Lux Fund deployed an ERC-3643 token in 2022 against the then-current Tokeny T-REX revision. Adoption of the canonical post-Tokeny `ERC-3643/ERC-3643` upstream requires a one-time migration. + +### Pre-conditions + +1. The Lux Fund issuer SHALL freeze new minting on the legacy contract before migration. +2. The issuer SHALL publish the migration block height ≥ 14 days in advance via on-chain `Paused` event and off-chain investor notice. +3. The issuer SHALL deploy the new T-REX 4.1.3 token, IdentityRegistry, ModularCompliance, TrustedIssuersRegistry, and ClaimTopicsRegistry contracts using the canonical upstream factories. + +### Holder migration path + +1. Each holder's existing ONCHAINID identity contract is reused — no holder action required if the identity is already a v2.x ONCHAINID. Identities below v2 SHALL be re-deployed by the issuer using `IdentityFactory.createIdentity` and the legacy claims re-attested by the same `IClaimIssuer`. +2.

-1. **Fault Isolation**: A crashing VM plugin cannot take down the entire node -2. **Language Agnosticism**: VMs can be implemented in any language, not just Go -3. **Independent Upgrades**: Plugins can be updated without restarting the node binary -4. **Security Boundaries**: Process-level sandboxing limits plugin capabilities -5. **Simplicity**: Binary distribution is simpler than shared library management across platforms - -The LPM tool follows the pattern established by package managers (apt, brew, npm) with repository-based distribution, version pinning, and checksum verification. This provides a familiar workflow for developers while maintaining the security guarantees needed for blockchain infrastructure. - -## Test Cases - -### Unit Tests +### Plugin Discovery -1. **Plugin Discovery** - - Verify plugins discovered from correct directory - - Test handling of invalid/corrupt binaries - - Validate VM ID parsing from filenames +**Plugin Registry**: Automatic discovery from: +- `~/.luxd/plugins/` - User plugins +- `/etc/luxd/plugins/` - System plugins +- Plugin load path specified in config -2. **LPM Commands** - - Test `install-vm` correctly downloads and places binaries - - Test `add-repository` correctly tracks remote repos - - Test `upgrade` correctly updates installed plugins +**Plugin Validation**: +- Version compatibility check +- Signature verification (optional) +- Capability permission validation +- Dependency resolution -3. **VM Loading** - - Verify VM initialization with valid config - - Test error handling for missing dependencies - - Validate version compatibility checks - -### Integration Tests - -1. **End-to-End Plugin Installation** - - Install VM via LPM - - Start node with new VM - - Verify chain creation succeeds - -2. **Custom VM Development** - - Build custom VM from template - - Install via local repository - - Deploy and test on local network - -## Backwards Compatibility - -This LP is additive; existing behavior remains unchanged.

Unlike single-chain platforms that force all applications to compete for the same resources, Lux provides **purpose-built chains** that are optimized for specific workloads while maintaining seamless interoperability. This LP provides a comprehensive overview of the Lux ecosystem, its architecture, chains, and unique capabilities. - -## Motivation - -Current blockchain platforms face fundamental challenges: quantum computing threatens existing cryptography, privacy is bolted on as an afterthought, single chains cannot scale, bridges are security liabilities, and key management remains centralized. Lux addresses these challenges with a purpose-built multi-chain architecture featuring native post-quantum cryptography, FHE-based privacy, protocol-native cross-chain messaging, and decentralized threshold signatures. - -**Why Lux?** - -| Challenge | Lux Solution | -|-----------|--------------| -| Quantum computing threatens cryptography | Native post-quantum cryptography (NIST FIPS 203/204/205) | -| Privacy is an afterthought | Native FHE (encrypted computation) and ZK proofs | -| Single chains don't scale | 14 purpose-built chains with horizontal scaling | -| Bridges get hacked | Protocol-native cross-chain messaging (Warp) | -| Centralized key management | Decentralized threshold signatures (MPC/TSS) | -| Slow finality | Sub-second finality via Snow consensus family | -| DEXs suffer from MEV | Native order book DEX with quantum-safe signatures | -

EIP-1559 Style Fee Model (Adapted for Lux) - -#### 1.1 Fee-Units (Generalized "Gas") - -Each transaction has a weight calculated as: - -``` -w(tx) = pByte × bytes + pExec × exec + pState × state -``` - -This `w(tx)` is the chain's "fee-units" (analogous to gas on Ethereum). - -#### 1.2 Transaction Fields - -Each transaction specifies: -- **maxFeePerUnit** (µLUX per fee-unit): Maximum total fee willing to pay -- **maxPriorityFeePerUnit** (µLUX per fee-unit): Maximum tip for validators -- **Resource limits**: maxBytes, maxExec, maxState (or combined maxWeight) - -#### 1.3 Payment Rule - -Let `basePerUnit` be the protocol-determined base rate (dynamic, like EIP-1559 baseFee): - -``` -effectiveTipPerUnit = min(maxPriorityFeePerUnit, maxFeePerUnit - basePerUnit) -totalPaid = w(tx) × (basePerUnit + effectiveTipPerUnit) -``` - -**Key insight**: Setting a high `maxFeePerUnit` does NOT cause overpayment—it just prevents tx from getting stuck if base fee rises. Users only pay `basePerUnit + effectiveTip`. - -#### 1.4 Inclusion Rule - -A transaction is includable if and only if: -1. `maxFeePerUnit >= basePerUnit` -2. It respects resource limits (maxBytes, maxExec, etc.) - -#### 1.5 Ordering Rule - -Validators order transactions by effective tip revenue: -- **Default**: Sort by `effectiveTipPerUnit` (simpler) -- **Alternative**: Sort by `effectiveTipTotal = effectiveTipPerUnit × w(tx)` (incentivizes larger txs) - -Recommended: Use `effectiveTipPerUnit` with a minimum tip floor to avoid "big tx dominates" pathologies. - -#### 1.6 Fee Distribution - -| Component | Destination | Rationale | -|-----------|-------------|-----------| -| Base fee | Burn (50%) + DAO Treasury (50%) | Monetary policy + governance-directed funding | -| Priority fee | Validators/Sequencers | Direct incentive to prioritize | - -**Governance Gauge Distribution**: The DAO's 50% treasury share is distributed according to **governance gauges** — token holders vote on allocation weights between: -- **Protocols**: DEX, lending, NFT marketplaces -- **Validators**: Staking rewards supplement -- **Liquidity Providers**: AMM incentives -- **Grants**: Builder funding, ecosystem development -- **Other**: Community-approved initiatives - -This creates a programmable incentive layer where the community directs protocol revenue. - -**Governance can adjust the burn/treasury split**, but priority fees ALWAYS go to validators. - -#### 1.7 Base Fee Update Algorithm - -After each block: - -```python -targetWeight = maxBlockWeight × targetUtilization - -if blockWeight == targetWeight: - newBase = oldBase -elif blockWeight > targetWeight: - delta = oldBase × maxChangeRate × (blockWeight - targetWeight) / targetWeight - newBase = min(oldBase + delta, maxBase) -else: - delta = oldBase × maxChangeRate × (targetWeight - blockWeight) / targetWeight - newBase = max(oldBase - delta, minBase) -``` - -**Default Parameters**: -- `targetUtilization`: 50% (like Ethereum) -- `maxChangeRate`: 12.5% per block (like Ethereum) -- `minBase`: 1 µLUX per fee-unit (floor) -- `maxBase`: Chain-specific (1000-10000 µLUX) - -### 2.

Attackers find the cheapest resource to spam. Multi-resource pricing ensures every dimension is priced. - -### Why EIP-1559 Style? - -EIP-1559 separates transaction pricing into base fee (protocol-determined) and priority fee (user-determined): -- **No overpayment**: Users only pay actual fee, not their max bid -- **Predictable**: Base fee changes gradually (≤12.5% per block) -- **Fair ordering**: Priority fee determines inclusion order -- **Fee burning**: Base fee burn creates deflationary pressure - -### Why Per-Unit Tips? - -Tips must be defined **per fee-unit**, not as flat amounts: -- Prevents gaming via transaction size manipulation -- Consistent ordering across different chain types -- Fair comparison between small and large transactions - -### Why Action Fees for D-Chain? - -Orderbooks have unique abuse patterns: -- **Cancel storms**: Flood cancels to disrupt matching -- **Tiny orders**: Create state bloat with minimal risk -- **Modify spam**: Rapid order modifications - -Action fees directly price these behaviors. - -## Backwards Compatibility - -- **C-Chain**: Existing gas pricing continues; this adds floor and congestion -- **Other chains**: New fee structure; old transactions may need updated fee estimates -- **Wallets**: Must update fee estimation APIs - -## Test Cases - -### Unit Tests - -1.

Effective tip: `min(maxPriorityFee, maxFee - baseFee)` -4. Total fee breakdown: `baseFee + priorityFee` with correct per-unit multiplication -5. Base fee update stays within `[minBase, maxBase]` -6. Base fee increases when `blockWeight > targetWeight` -7. Base fee decreases when `blockWeight < targetWeight` -8. Fee distribution: `burnBps + treasuryBps == 10000` -9. Emergency constraints enforced (≤2x floor raise only) -10. Warp payload encoding/decoding roundtrips - -### Integration Tests - -1. Full governance flow: propose → vote → timelock → execute → Warp -2. Multi-chain fee update propagation -3. Congestion response under sustained load -4.

The address format (Bech32) and transaction structure differ from EVM. Coin type 9000 (SLIP-44 registered for Avalanche) is the established standard for this chain type and maintains compatibility with existing Avalanche wallet tooling. - -### Why Not a Custom Lux Coin Type? - -A custom coin type would: -- Break compatibility with existing Ethereum wallets -- Require all hardware wallets to add Lux-specific firmware -- Add unnecessary complexity with zero security benefit -- Prevent "add network" flows in MetaMask from working +Design choices favor simplicity and reliability while meeting Lux performance and ecosystem requirements. ## Backwards Compatibility -This is a formalization of existing practice. All deployed chains already use these derivation paths. No migration needed. +Additive change; existing APIs and formats remain valid. Adoption is opt-in. ## Security Considerations -- **Mnemonic index 0** is locked when used in `initialStakedFunds` — do not use for operational transactions -- **Chain ID replay protection** (EIP-155) prevents cross-chain transaction replay between EVM subnets -- **P/X transactions** use the Avalanche serialization format with network ID for replay protection -- **Same mnemonic, different addresses**: Users must understand that P-Chain/X-Chain addresses look different from EVM addresses even when derived from the same seed -- **Hardware wallet signing**: Always verify the derivation path shown on the hardware device matches the expected chain type +Consider typical threat models (input validation, replay/DoS resistance, key handling).

Instead of permanently destroying value, 50% is actually burned (deflationary) while 50% is tithed to the DAO as protocol-owned liquidity (POL). This creates a sustainable mechanism where burns contribute to protocol-controlled resources that can be deployed via governance into liquidity pools and other productive uses. - -## Motivation - -Current EVM implementations treat burns to dead addresses as permanent value destruction: - -1. **Lost Value**: Burns to 0x0 or 0xdead permanently remove assets from circulation -2. **No Protocol Benefit**: Destroyed value doesn't benefit the protocol or community -3. **Deflationary Spiral**: Pure deflationary mechanics can harm liquidity -4. **Accidental Loss**: Users may accidentally send to 0x0 with no recourse - -The Dead Precompile addresses these by: - -| Problem | Solution | -|---------|----------| -| Permanent destruction | 50% burn + 50% treasury | -| No protocol benefit | Protocol-owned liquidity grows | -| Liquidity drain | POL deployed to AMM pools | -| Accidental sends | Governance can review edge cases | - -**Design Philosophy**: To truly delete an asset from existence, users must destroy the contract itself - not just send tokens to a dead address. - -## Specification - -### 1.

A DataSeal binds a cryptographic fingerprint of any digital asset -- documents, AI models, media files, financial records, sensor readings -- to the Z-Chain Receipt Registry (LP-0530) via Poseidon2 hashing (LP-3658) and STARK/SNARK verification (LP-0510). Seals are independently verifiable without reliance on any central authority, exportable cross-chain via Groth16 wrappers, and optionally privacy-preserving through FHE encryption (LP-200) or ZK selective disclosure. The protocol provides a scalable, blockchain-anchored alternative to centralized verification services, enabling court-admissible proof of data authenticity, AI model provenance, media integrity, and regulatory compliance at enterprise scale. - -## Motivation - -### The Trust Crisis - -Digital data integrity faces unprecedented challenges: - -1. **AI-Generated Content**: Deepfakes, synthetic media, and LLM-generated text are indistinguishable from authentic content, eroding trust in journalism, legal evidence, and business records. -2. **Data Manipulation**: Cybercriminals alter financial records, audit logs, and compliance documents at scale. By 2030, fraud costs are projected to exceed $10 trillion annually. -3. **Model Tampering**: AI/ML models can be poisoned, backdoored, or altered post-training without detection, creating liability for enterprises deploying AI systems. -4. **Regulatory Pressure**: The EU AI Act, US Executive Order on AI Safety, and emerging global frameworks demand auditable, verifiable AI governance and data provenance. - -### Why Existing Solutions Fail - -| Approach | Limitation | -|----------|-----------| -| Manual review | Does not scale; subjective | -| Centralized signatories | Single point of failure; trust bottleneck | -| Private hashing | No independent verification; non-repudiation gap | -| Timestamping services | Centralized; no proof of content integrity | -| Traditional blockchain | Expensive at scale; no privacy; no ZK proofs | - -### The Lux Advantage - -The Lux FHE+ZK stack provides a unique combination of capabilities: - -- **ZK Proof Verification** (LP-0510): Verify computational integrity without revealing inputs -- **Receipt Registry** (LP-0530): Canonical on-chain proof storage with Merkle accumulator -- **Poseidon2 Hashing** (LP-3658): ZK-friendly, post-quantum-safe cryptographic fingerprints at 2M hashes/sec -- **FHE Encryption** (LP-200): Compute over encrypted data without decryption -- **fheCRDT** (LP-6500): Privacy-preserving document management with DA integration -- **Cross-Chain Export** (LP-0530): Groth16 wrapper proofs for external verification - -VDIS unifies these primitives into a single, product-level protocol. - -## Specification - -### Core Concepts - -#### DataSeal - -A **DataSeal** is an immutable cryptographic binding between: - -1.

Minimum stake requirement for high-volume sealers - -### Cross-Chain Verification Trust - -Exported seals are only as trustworthy as the Groth16 proof and the light client verification. Users should verify: - -1. The Groth16 verification key matches the known Z-Chain circuit -2. The Merkle root is included in a finalized Z-Chain block -3. The light client proof is valid against the known validator set - -### Quantum Resistance - -All cryptographic operations in VDIS are post-quantum safe: - -- Poseidon2: Algebraic hash, no discrete log dependency -- STARK proofs: Hash-based, quantum-resistant -- FHE: Lattice-based, quantum-resistant - -Groth16 export proofs (pairing-based) are NOT post-quantum safe.

A seal achieves **quantum-final** status when the block containing its receipt passes the Quasar consensus Event Horizon — the point at which dual classical (BLS) and post-quantum (lattice) certificates have been aggregated. Once quantum-final, a seal cannot be reversed by any adversary, including one with access to a cryptographically relevant quantum computer. - -This LP specifies the finality states, the transition rules, and the on-chain interface for querying seal finality status. - -## Motivation - -### The Finality Gap - -Data integrity seals are only as trustworthy as the finality of the chain they're anchored to. Existing approaches anchor to: - -- **Bitcoin**: Probabilistic finality. A 6-block confirmation (~60 minutes) provides high confidence but never mathematical certainty. A sufficiently motivated state actor with >50% hash power can reorg. -- **Ethereum**: Committee-based finality (~13 minutes to finalization). Relies on BLS signatures over BN254 — vulnerable to quantum attack via Shor's algorithm on the pairing group. - -Neither provides the guarantee that high-stakes use cases demand: - -| Use Case | Requirement | BTC/ETH Finality | -|:---------|:------------|:-----------------| -| Court-admissible evidence | Mathematically irreversible | Insufficient | -| Regulatory compliance (EU AI Act) | Provably tamper-proof | Time-dependent | -| Whistleblower protection | Cannot be reversed by state actors | Insufficient | -| Insurance claims | Survives dispute periods (years) | Quantum-vulnerable | -| Medical records | Long-term integrity (decades) | Quantum-vulnerable | - -### The Quantum Threat to Seal Integrity - -When a cryptographically relevant quantum computer (CRQC) exists: - -1. **ECDSA breaks** → Bitcoin transaction signatures can be forged → anchored roots can be replaced -2. **BLS breaks** → Ethereum validator attestations can be faked → finalized blocks can be reversed -3. **Every seal anchored to BTC/ETH loses its guarantee** - -This is not a theoretical concern. NIST has standardized post-quantum algorithms (FIPS 203-205) specifically because the timeline for CRQC is measured in years, not decades. Seals created today must remain valid for decades. - -### Lux Solution: Quantum Event Horizon - -The Quasar consensus engine provides a finality mechanism that survives quantum attacks: the **Event Horizon**. A seal that passes the Event Horizon has dual-certificate finality — both classical and post-quantum signatures attest to its inclusion in the canonical chain. No future adversary, regardless of computational capability, can reverse it. - -## Specification - -### Seal Finality States - -A data integrity seal transitions through four finality states: - -``` -┌──────────┐ ┌───────────┐ ┌──────────────┐ ┌────────────────┐ -│ PENDING │───>│ CLASSICAL │───>│ QUANTUM │───>│ HORIZON-FINAL │ -│ │ │ FINAL │ │ FINAL │ │ │ -│ In mempool│ │ BLS cert │ │ BLS + Lattice│ │ Checkpointed │ -│ or block │ │ only │ │ dual cert │ │ in Event │ -│ │ │ │ │ │ │ Horizon │ -└──────────┘ └───────────┘ └──────────────┘ └────────────────┘ - │ │ │ │ - ~0s ~500ms ~3s ~6s -``` - -#### State 1: PENDING - -The seal transaction has been submitted but not yet included in a block, or is in a block that has not received sufficient validator votes. - -**Security**: No finality guarantee. Transaction can be dropped or reordered. - -#### State 2: CLASSICAL_FINAL - -The block containing the seal's receipt has received a BLS aggregate signature from ≥2/3 of validators by stake weight. - -**Security**: Byzantine fault tolerant under classical assumptions. Safe against any adversary without a quantum computer. Equivalent to Ethereum's finality. - -**Time**: ~500ms from block proposal. - -#### State 3: QUANTUM_FINAL - -The block (or its containing quantum bundle) has received both: -- BLS aggregate signature (classical certificate) -- Lattice-based aggregate signature via Ringtail protocol (post-quantum certificate) - -**Security**: Safe against any adversary, including one with a CRQC. The lattice certificate uses Ring-LWE based signatures requiring ≥2^160 operations to forge. - -**Time**: ~3 seconds from block proposal (quantum bundles aggregate every ~3 seconds). - -#### State 4: HORIZON_FINAL - -The quantum-final block has been included in an Event Horizon checkpoint. The checkpoint itself has been signed by ≥2/3 of validators with both classical and post-quantum signatures, and the checkpoint references all prior checkpoints in a hash chain. - -**Security**: Maximum finality. Even if the entire validator set is replaced, the checkpoint chain provides an independent proof of finality. Equivalent to a "point of no return" — no future consensus execution can produce a conflicting history. - -**Time**: ~6 seconds from block proposal (checkpoints every ~6 seconds). - -### On-Chain Interface - -```solidity -// SPDX-License-Identifier: MIT -pragma solidity ^0.8.25;

Using lattice signatures alone would: - -1. Increase block size significantly -2. Slow down consensus -3. Lose the performance benefit of BLS aggregation - -The dual approach provides: -- **Fast classical finality** (~500ms) for latency-sensitive applications -- **Quantum finality** (~3s) for long-term applications -- **Graceful degradation** — if lattice schemes are found vulnerable, classical certificates still hold (and vice versa) -- **Migration path** — when quantum computers arrive, the system continues operating on lattice certificates alone - -### Why Checkpoint Chain? - -The Event Horizon checkpoint chain provides finality proofs that are: - -1. **Self-contained** — no need to replay consensus from genesis -2. **Compact** — a single checkpoint + Merkle proof suffices -3. **Independently verifiable** — any third party can verify without running a node -4. **Long-lived** — checkpoints remain valid forever (no expiration) - -### Why Poseidon2 for Checkpoint Hashing? - -Poseidon2 is used throughout the checkpoint chain (not just the receipt accumulator) because: - -1. **ZK-friendly** — checkpoint proofs can be wrapped in ZK proofs for cross-chain export -2. **Post-quantum safe** — the checkpoint chain itself doesn't depend on DLP assumptions -3. **Consistent** — same hash function at every layer reduces implementation complexity and attack surface - -## Backwards Compatibility - -This LP extends LP-0530 (Receipt Registry) and LP-0535 (Data Integrity Seal) without breaking changes. Existing receipts and seals automatically receive finality tracking — the finality state is derived from consensus, not from the receipt itself. - -Applications that do not query finality status are unaffected. - -## Test Cases - -### Finality State Transitions - -1. **Seal created** → state = `Pending` -2. **Block receives BLS aggregate (≥2/3 stake)** → state = `ClassicalFinal` -3. **Quantum bundle includes block, receives lattice aggregate** → state = `QuantumFinal` -4. **Checkpoint includes bundle** → state = `HorizonFinal` - -### Edge Cases - -5. **Block reorg before classical finality** — seal returns to `Pending`, re-included in new block -6. **Lattice key rotation mid-bundle** — bundle uses keys from the epoch that started it -7. **Validator set change between classical and quantum finality** — quantum certificate uses the validator set at bundle creation time -8. **Cross-chain export of horizon proof** — Groth16 proof verifiable on Ethereum mainnet - -### Performance Targets - -| Metric | Target | -|:-------|:-------| -| Time to `ClassicalFinal` | <500ms | -| Time to `QuantumFinal` | <3s | -| Time to `HorizonFinal` | <6s | -| Checkpoint proof size | <2KB | -| Groth16 export proof size | <256 bytes | -| Export proof verification gas (EVM) | <200K gas | - -## Security Considerations - -### Quantum Adversary Model - -The primary adversary is a state-level actor with access to a CRQC capable of breaking: -- ECDSA (secp256k1, secp256r1) -- BLS12-381 -- Any pairing-based cryptography - -Against this adversary: -- `ClassicalFinal` seals are **NOT safe** — BLS certificates can be forged -- `QuantumFinal` seals are **safe** — lattice certificates require ≥2^160 operations -- `HorizonFinal` seals are **maximally safe** — checkpoint chain provides independent verification - -### Signature Agility - -The dual-certificate design provides cryptographic agility. If either scheme is found vulnerable: - -- **BLS broken (quantum attack)**: Lattice certificates alone provide finality. Classical finality state is skipped. -- **Lattice broken (cryptanalytic advance)**: BLS certificates provide finality. Lattice scheme is replaced via governance. -- **Both broken**: Consensus halts safely (no unsafe finality granted). New signature scheme deployed via hard fork. - -### Long-Term Seal Validity - -Seals at `HorizonFinal` remain valid indefinitely because: - -1. The Poseidon2 accumulator root is self-proving (no external dependency) -2. The dual certificates are independently verifiable -3. The checkpoint chain forms an immutable append-only log -4. Cross-chain Groth16 exports create standalone proofs - -Even if the Lux Network itself ceased to operate, any party holding a horizon proof can independently verify the seal's integrity. - -## References - -- [LP-0530: Z-Chain Receipt Registry](./lp-0530-receipt-registry.md) -- [LP-0535: Verifiable Data Integrity Seal Protocol](./lp-0535-verifiable-data-integrity-seal.md) -- [LP-3658: Poseidon2 Precompile](./lp-3658-poseidon2-precompile.md) -- [LP-0510: STARK Verification Precompiles](./lp-0510-stark-verifier-precompile.md) -- [LP-110: Quasar Consensus Protocol](./lp-110.md) -- NIST FIPS 203: ML-KEM (Module-Lattice-Based Key Encapsulation) -- NIST FIPS 204: ML-DSA (Module-Lattice-Based Digital Signatures) -- NIST FIPS 205: SLH-DSA (Stateless Hash-Based Digital Signatures) - -## Implementation - -### Quasar Consensus Engine - -**Repository**: [github.com/luxfi/consensus](https://github.com/luxfi/consensus) - -| Directory | Component | -|:----------|:----------| -| `protocol/quasar/` | Core Quasar engine with quantum bundling | -| `protocol/quasar/quantum_block.go` | Async quantum block production | -| `protocol/quasar/epoch.go` | Lattice key rotation and epoch management | -| `protocol/horizon/` | Event Horizon checkpoint algorithms | -| `core/dag/horizon.go` | DAG-level horizon interface | - -### FHE Seal Examples - -**Repository**: [github.com/luxfi/fhe](https://github.com/luxfi/fhe) - -| Example | Description | -|:--------|:------------| -| `cmd/seal` | Boolean-circuit document sealing with XNOR+AND verification | -| `cmd/provenance` | AI model provenance via encrypted hash comparison | -| `cmd/mediaseal` | Media content authentication and tamper detection | - -## Copyright - -Copyright and related rights waived via [CC0](https://creativecommons.org/publicdomain/zero/1.0/). diff --git a/LPs/lp-0900-lux-version-chronology.md b/LPs/lp-0900-lux-version-chronology.md new file mode 100644 index 00000000..b2b0e9f0 --- /dev/null +++ b/LPs/lp-0900-lux-version-chronology.md @@ -0,0 +1,88 @@ +--- +lp: 900 +title: Lux Version Chronology --- 1.0 / 2.0 / 3.0 / 4.0 +description: Canonical version timeline for the Lux Network from 2020 mainnet through the GPU-native 4.0 activation on 2026-02-14. +author: Zach Kelling (@zeekay) +discussions-to: https://github.com/luxfi/lps/discussions +status: Final +type: Informational +category: Meta +created: 2026-02-14 +tags: [chronology, version-history, meta, gpu-native, quasar, 9-chain-topology] +--- + +## Abstract + +This LP is the canonical chronology of the Lux Network: the four +locked version milestones, their activation dates, the consensus and +execution stack at each step, and how the 9-chain topology and its +financial-rail core (DEX + EVM + FHE) evolved into production.

The motivation stems from the well-recognized “quantum threat” to blockchain security: core algorithms like ECDSA (used for digital signatures) and ECDH are vulnerable to Shor’s algorithm, meaning a sufficiently powerful quantum computer could break private keys and forge signatures. While such quantum computers are not yet available, Lux adopts a proactive stance. This proposal evaluates and selects post-quantum (PQ) algorithms for crucial components such as transaction signatures and hashing. It highlights NIST’s recent standardization efforts, noting that the first suite of PQ algorithms (finalized in 2022) are based on structured lattices and hash-based cryptography. In particular, Lux plans to support a lattice-based signature scheme (e.g., CRYSTALS-Dilithium or a variant) for validator authentication and user wallets, as these schemes rely on mathematical problems (lattice Short Vector problems) believed to be resistant to quantum attacks. Additionally, hash-based signatures like XMSS or SPHINCS+ are considered for one-time or few-time signatures, given their minimal security assumptions (collision-resistant hashes) and existing standardization (XMSS is specified in RFC 8391). LP-4 details a transition plan whereby Lux accounts can upgrade from classical ECDSA/secp256k1 keys to dual-key addresses that include a PQ public key. This ensures backward compatibility (similar to how Ethereum is exploring introducing Lamport or Winternitz one-time signatures for account security). The proposal also addresses performance considerations: PQ signatures are generally larger or slower to verify than ECDSA, which could impact block size and verification time. To mitigate this, Lux may leverage hybrid approaches (e.g., using efficient lattice signatures and optimizing verification via batching or elliptic-curve accelerators... - -## Motivation - -[TODO] - -## Specification - -[TODO] - -## Rationale - -[TODO] - -## Backwards Compatibility - -[TODO] - -## Security Considerations - -[TODO] - -## Implementation - -### ML-DSA Post-Quantum Signatures (FIPS 204) - -**Location**: `~/work/lux/crypto/mldsa/` -**GitHub**: [`github.com/luxfi/node/tree/main/crypto/mldsa`](https://github.com/luxfi/node) - -**Key Files**: -- [`mldsa.go`](https://github.com/luxfi/node/blob/main/crypto/mldsa/mldsa.go) - ML-DSA-65 signature implementation (7.7 KB) -- [`mldsa_test.go`](https://github.com/luxfi/node/blob/main/crypto/mldsa/mldsa_test.go) - Comprehensive test suite with 11 test cases (6.2 KB) - -**Algorithm**: ML-DSA-65 (Dilithium, NIST Level 3) -- Public Key Size: 1,952 bytes -- Signature Size: 3,293 bytes (per NIST FIPS 204) -- Quantum Security: ~192 bits - -**Testing**: -```bash -cd ~/work/lux/crypto/mldsa -go test -v ./... -``` - -### EVM ML-DSA Precompile - -**Location**: `~/work/lux/evm/precompile/contracts/mldsa/` -**GitHub**: [`github.com/luxfi/evm/tree/main/precompile/contracts/mldsa`](https://github.com/luxfi/evm/tree/main/precompile/contracts/mldsa) - -**Key Files**: -- [`contract.go`](https://github.com/luxfi/evm/blob/main/precompile/contracts/mldsa/contract.go) - Precompile contract (4.3 KB) -- [`contract_test.go`](https://github.com/luxfi/evm/blob/main/precompile/contracts/mldsa/contract_test.go) - Precompile tests (7.4 KB) -- [`IMLDSA.sol`](https://github.com/luxfi/evm/blob/main/precompile/contracts/mldsa/IMLDSA.sol) - Solidity interface (7.1 KB) - -**Precompile Address**: `0x0200000000000000000000000000000000000006` -**Gas Cost**: 100,000 base + 10 per message byte - -**Testing**: -```bash -cd ~/work/lux/evm/precompile/contracts/mldsa -go test -v ./... -``` - -## Test Cases - -### Unit Tests - -1. **Cryptographic Primitives** - - Test key generation - - Verify signature creation - - Test signature verification - -2. **Post-Quantum Security** - - Verify NIST compliance - - Test parameter validation - - Validate security levels - -3. **Performance Benchmarks** - - Measure key generation time - - Benchmark signing operations - - Test verification throughput - -### Integration Tests - -1. **Hybrid Signature Schemes** - - Test classical-PQ combinations - - Verify fallback mechanisms - - Test key rotation - -2. **Network Integration** - - Test consensus with PQ signatures - - Verify cross-chain compatibility - - Test upgrade transitions - diff --git a/LPs/lp-2005-quantum-safe-wallets-and-multisig-standard.md b/LPs/lp-2005-quantum-safe-wallets-and-multisig-standard.md deleted file mode 100644 index fa42301f..00000000 --- a/LPs/lp-2005-quantum-safe-wallets-and-multisig-standard.md +++ /dev/null @@ -1,127 +0,0 @@ ---- -lp: 2005 -title: Lux Quantum-Safe Wallets and Multisig Standard -tags: [pqc, wallet, threshold-crypto] -description: Focuses on the design of Lux's quantum-safe wallet infrastructure, including a new multisignature (multisig) standard that remains secure against quantum adversaries. -author: Lux Network Team (@luxfi) -discussions-to: https://github.com/luxfi/lps/discussions -status: Review -requires: 4 -type: Standards Track -category: Core -created: 2025-01-28 -activation: - flag: lp5-quantum-safe-wallets - hfName: "" - activationHeight: "0" -order: 5 ---- - -> **See also**: [LP-4: Quantum-Resistant Cryptography Integration in Lux](/docs/lp-4-quantum-resistant-cryptography-integration-in-lux/) - -## Abstract - -## Activation - -| Parameter | Value | -|--------------------|-------------------------------------------------| -| Flag string | `lp5-quantum-safe-wallets` | -| Default in code | N/A | -| Deployment branch | N/A | -| Roll-out criteria | N/A | -| Back-off plan | N/A | - -LP-5 focuses on the design of Lux’s quantum-safe wallet infrastructure, including a new multisignature (multisig) standard that remains secure against quantum adversaries. As Lux transitions its core signatures to post-quantum algorithms (per LP-4), user-facing wallet technology must follow suit. This proposal introduces support for hash-based and lattice-based signature schemes in Lux wallets. It specifies that a user’s Lux address can be associated with a quantum-resistant public key, such as an XMSS or Dilithium public key, instead of or in addition to the traditional elliptic curve key. A major component is the Lux Safe, a quantum-safe multisig wallet service, which LP-5 formalizes at the protocol level. In a Lux Safe multisig account, multiple parties each hold a share of a post-quantum key or have independent PQ keys, and the account requires a threshold of signatures on any transaction. The use of threshold signing is carefully designed to be compatible with PQ algorithms. For instance, if using lattice-based signatures, the proposal outlines how to aggregate partial signatures or how to perform a secure distributed key generation such that no single device ever holds the full private key (applying MPC techniques akin to those used in threshold ECDSA, but now in a lattice context). Recognizing the novelty of threshold PQ signatures, LP-5 references ongoing research in this arena – for example, experiments combining Falcon (lattice signature) with threshold schemes, and stateful hash-based multisigs where each cosigner uses a distinct XMSS tree for each approval. The Lux Safe design takes inspiration from conventional multisigs (like Bitcoin’s M-of-N script and Ethereum’s smart contract wallets) but builds in quantum resilience. It also emphasizes usability and security: for instance, using a hierarchical derivation of many one-time hash-based keys under the hood so that the wallet can generate a new PQ one-time address for each transaction (mitigating reuse i... The proposal cites the IETF’s XMSS standard (RFC 8391) as evidence that hash-based signatures are mature enough for production use. It also references that Lux Safe is already implemented as a product in the ecosystem, highlighting it as “our quantum-safe multisig wallet”, to be integrated at protocol level. Through LP-5, Lux aims to provide users and institutions with high assurance that even if large-scale quantum computers emerge, funds secured in Lux multisig wallets (which might protect exchange reserves or DAO treasuries) will remain safe. This enhances Lux’s appeal for “quantum-resistant custody.” In summary, LP-5 extends Lux’s security to the user and application layer by defining standards for quantum-resistant key management and multisignature transactions, aligning with global efforts (by NIST and IETF) to make cryptocurrency systems ready for the quantum age. - -## Motivation - -[TODO] - -## Specification - -[TODO] - -## Rationale - -[TODO] - -## Backwards Compatibility - -[TODO] - -## Security Considerations - -[TODO] - -## Implementation - -### Lux Safe Multisig Wallet - -**Location**: `~/work/lux/safe/` -**GitHub**: [`github.com/luxfi/safe/tree/main`](https://github.com/luxfi/safe/tree/main) - -**Quantum-Safe Wallet Components**: -- [`app/`]() - Next.js wallet application (React, TypeScript) -- [`react/`]() - Reusable React components for Safe interface -- [`contracts/`]() - Smart contract module (Solidity) - -**Key Features**: -- M-of-N multisig with post-quantum key support -- Hierarchical deterministic (HD) wallet derivation -- One-time signature capability (XMSS/hash-based) -- Zero-knowledge proof integration for privacy - -**Testing & Documentation**: -```bash -cd ~/work/lux/safe/app -npm install && npm test -``` - -### Wallet CLI and Key Management - -**Location**: `~/work/lux/cli/cmd/` -**GitHub**: [`github.com/luxfi/cli/tree/main/cmd`](https://github.com/luxfi/cli/tree/main/cmd) - -**Quantum-Safe Features**: -- Post-quantum key generation (ML-DSA, SLH-DSA, ML-KEM support) -- Hybrid key management (classical + post-quantum) -- Secure key storage and recovery -- Transaction signing with quantum-resistant algorithms - -**Testing**: -```bash -cd ~/work/lux/cli -make test # Run full CLI test suite -``` - -## Test Cases - -### Unit Tests - -1. **Cryptographic Primitives** - - Test key generation - - Verify signature creation - - Test signature verification - -2. **Post-Quantum Security** - - Verify NIST compliance - - Test parameter validation - - Validate security levels - -3. **Performance Benchmarks** - - Measure key generation time - - Benchmark signing operations - - Test verification throughput - -### Integration Tests - -1. **Hybrid Signature Schemes** - - Test classical-PQ combinations - - Verify fallback mechanisms - - Test key rotation - -2. **Network Integration** - - Test consensus with PQ signatures - - Verify cross-chain compatibility - - Test upgrade transitions - diff --git a/LPs/lp-2099-q-chain-quantum-secure-consensus-protocol-family-quasar.md b/LPs/lp-2099-q-chain-quantum-secure-consensus-protocol-family-quasar.md deleted file mode 100644 index 46ba9c1c..00000000 --- a/LPs/lp-2099-q-chain-quantum-secure-consensus-protocol-family-quasar.md +++ /dev/null @@ -1,1009 +0,0 @@ ---- -lp: 2099 -title: Q-Chain – Root PQC with Quasar Consensus Protocol Family -description: Comprehensive specification of Q-Chain as the root Post-Quantum Chain with Quasar consensus, featuring dual-certificate finality and recursive PQC architecture -author: Lux Network Team (@luxfi) -discussions-to: https://github.com/luxfi/lps/discussions -status: Review -type: Standards Track -category: Core -created: 2025-08-05 -updated: 2025-07-25 -requires: 4, 5, 0, 70 -tags: [pqc, consensus, core] -order: 99 ---- - -## Abstract - -This LP introduces **Q-Chain** and the **Quasar consensus protocol family**, Lux Network's quantum-secure blockchain that serves as the platform management chain in Lux 2.0, replacing P-Chain from Lux 1.0. Q-Chain achieves both fast classical consensus and post-quantum finality via an integrated hybrid consensus framework. Beyond quantum security, Q-Chain manages validator coordination, staking operations, chain creation, and network governance. It supports linear and DAG-based transaction processing through multiple consensus engines, and provides **dual-certificate finality** combining BLS-based classical finalization and Ringtail-based quantum-resistant threshold signatures. The protocol achieves sub-second finality while maintaining security against both classical and quantum adversaries. - -## Motivation - -Blockchain networks face an impending quantum threat that could undermine current cryptographic foundations: - -1. **Quantum Computing Threat**: Shor's algorithm can break elliptic curve cryptography, threatening all current blockchain signatures -2. **Performance Requirements**: Post-quantum cryptography must not sacrifice the sub-second finality users expect -3. **Transition Complexity**: Networks need smooth migration paths from classical to quantum-safe cryptography -4. **Unified Framework**: Multiple consensus variants (linear chains, DAGs) need consistent quantum protection - -Q-Chain addresses these challenges by providing a modular, high-performance consensus stack with built-in quantum resistance. - -## Post-Quantum Chains (PQC) – General - -A Post-Quantum Chain (PQC) is any chain in the Lux ecosystem that: - -- Runs the Lux PQ consensus (post-quantum BFT), -- Has a validator set backed by stake in LUX or a chain whose security_token ultimately resolves to LUX, -- Can accept checkpoint transactions from downstream chains, -- Can emit checkpoints to an upstream PQC (often Q-Chain). - -### Properties - -- **High-security**: PQC consensus uses post-quantum signatures (e.g. lattice/hash-based), with crypto-agility to allow future upgrades. -- **Configurable throughput**: A PQC can be low-throughput (like Q-Chain) or medium-throughput (e.g. a regional PQC) depending on its role. -- **Recursive**: A PQC itself may be a "parent" to: - - classical LSCs / L2s that use its stateRoot as their finality anchor, - - or even to other PQCs (if you want multi-layer PQ trees). - -### Requirements - -In RFC language: - -A PQC MUST: - - Run LuxPQConsensus (parametrized PBFT-like protocol with PQ signatures). - - Accept Checkpoint(tx) messages from authorized child chains. - - Produce Checkpoint(tx) messages to its parent PQC or to Q-Chain. - -A PQC MAY: - - Run application logic (EVM/WASM/etc.). - - Maintain its own QSF-like fee market for its children, denominated in its own security_token, - as long as it ultimately settles to LUX when checkpointing to Q-Chain. - -## Q-Chain – Root PQC - -Q-Chain is the distinguished root Post-Quantum Chain of the Lux ecosystem. It is a high-security, low-throughput PQC that: - -- Is validated by LUX-staked validators registered on P-Chain, -- Stores checkpoints from all chains and from other PQCs, -- Implements the global Quantum Security Fee (QSF) fee market in LUX on a per-byte basis, -- Acts as the canonical root of finality from which all other PQCs and Liquidity-Secured Chains derive their long-term safety. - -### Checkpoint Inclusion Mechanism - -The checkpoint inclusion mechanism is cryptographically sound and builds on Lux's post-quantum consensus and signing infrastructure: - -#### 1. Merkle Mountain Ranges (MMR) for Efficient Proofs - -Each child chain (LSC, L2, or PQC) maintains a Merkle Mountain Range of its block headers: - -```go -type ChainMMR struct { - peaks []Hash // Current MMR peaks - height uint64 // Current height - chainID ChainID // Source chain identifier - lastCheckpoint uint64 // Last checkpointed height -} - -func (mmr *ChainMMR) AddBlock(header BlockHeader) { - // Add block to MMR, update peaks - mmr.peaks = mmr.updatePeaks(header.Hash()) - mmr.height++ -} - -func (mmr *ChainMMR) GenerateProof(targetHeight uint64) *MMRProof { - // Generate inclusion proof for specific height - return generateMMRProof(mmr.peaks, targetHeight) -} -``` - -#### 2. Post-Quantum Signed Checkpoints - -Checkpoints are signed using the existing Lux PQ consensus infrastructure: - -```go -type Checkpoint struct { - ChainID ChainID // Source chain ID - StartHeight uint64 // First block in this checkpoint - EndHeight uint64 // Last block in this checkpoint - StartRoot Hash // MMR root at StartHeight-1 - EndRoot Hash // MMR root at EndHeight - BlockCount uint64 // Number of blocks included - StateRoot Hash // Final state root - Proof *MMRProof // MMR inclusion proof - QSFFee uint64 // Quantum Security Fee paid - ValidatorSet ValidatorSetID // Validator set ID -} - -type SignedCheckpoint struct { - Checkpoint Checkpoint - BLSsig []byte // Classical BLS aggregate signature - RingtailSig []byte // Post-quantum threshold signature - SignerBitmap []byte // Bitmap of signing validators -} -``` - -#### 3. Dual-Signature Verification - -Q-Chain validates checkpoints using both classical and post-quantum signatures: - -```go -func (q *QuasarConsensus) VerifyCheckpoint(signed *SignedCheckpoint) bool { - // 1. Verify MMR proof structure - if !verifyMMRProof(signed.Checkpoint.Proof, signed.Checkpoint.StartRoot, - signed.Checkpoint.EndRoot, signed.Checkpoint.BlockCount) { - return false - } - - // 2. Verify classical BLS signature - if !q.blsAgg.Verify(signed.Checkpoint.Hash(), signed.BLSsig) { - return false - } - - // 3. Verify post-quantum Ringtail signature - if !q.ringtail.Verify(signed.Checkpoint.Hash(), signed.RingtailSig) { - return false - } - - // 4. Verify validator set matches current epoch - currentSet := q.getCurrentValidatorSet() - if !currentSet.Matches(signed.ValidatorSet) { - return false - } - - // 5. Verify QSF fee payment - if !q.verifyQSFPayment(signed.Checkpoint.QSFFee, signed.Checkpoint.BlockCount) { - return false - } - - return true -} -``` - -#### 4. Verkle Tree Integration for State Proofs - -For chains that need state verification (not just block inclusion): - -```go -type StateProof struct { - StateRoot Hash // Root of state trie - Key []byte // Key being proven - Value []byte // Value at key - Proof []byte // Verkle proof - BlockHeight uint64 // Block height for this state -} - -func (q *QuasarConsensus) VerifyStateProof(proof *StateProof, checkpoint *Checkpoint) bool { - // Verify state proof against checkpoint's state root - return q.verkleTree.Verify(proof.StateRoot, proof.Key, proof.Value, proof.Proof) -} -``` - -#### 5. Checkpoint Processing Flow - -```sql -1. Child chain produces blocks and updates its MMR -2. At checkpoint interval (e.g., every 100 blocks): - - Generate MMR proof from last checkpoint to current height - - Create Checkpoint struct with metadata - - Sign with dual BLS+Ringtail signatures -3. Submit SignedCheckpoint to Q-Chain (or parent PQC) -4. Q-Chain validates: - - Cryptographic proofs (MMR + signatures) - - Validator set authorization - - QSF fee payment -5. If valid, Q-Chain includes checkpoint in next block -6. Q-Chain updates its global state with new chain head -``` - -#### 6. Security Properties - -- **Post-Quantum Security**: All signatures use Lux's dual BLS+Ringtail scheme -- **Efficient Proofs**: MMR provides O(log n) proofs for arbitrary block ranges -- **State Verifiability**: Optional Verkle proofs for state transitions -- **Economic Security**: QSF fees paid in LUX provide Sybil resistance -- **Validator Accountability**: Signer bitmaps enable slashing for misbehavior -- **Crypto-Agility**: Signature schemes can be upgraded via governance - -#### 7. Performance Characteristics - -- **Proof Size**: ~1-2 KB per checkpoint (MMR + signatures) -- **Verification Time**: ~5-10ms on modern hardware -- **Checkpoint Frequency**: Configurable per chain (e.g., every 10-1000 blocks) -- **Throughput**: Q-Chain can process 1000+ checkpoints/second -- **Storage**: MMR peaks allow pruning of old block data - -This mechanism ensures that Q-Chain can securely and efficiently include proofs of other networks' blocks while maintaining the full post-quantum security guarantees of the Lux consensus protocol. - -## The Quasar Consensus Stack - -Quasar is Lux Network's completely rewritten consensus protocol family, designed from scratch with quantum security, verkle trees, witness support, and FPC (Fast Path Consensus) similar to Sui: - -### 1. Photon – Sampling-Based Consensus - -The foundation layer using network sampling for agreement: - -```go -type PhotonConsensus struct { - // Binary consensus on a single bit - Preference bool - Confidence int - K int // Sample size - Alpha int // Quorum threshold - Beta int // Confidence threshold -} - -func (p *PhotonConsensus) Query(validators []Validator) bool { - sample := randomSample(validators, p.K) - votes := queryPreference(sample) - - if votes >= p.Alpha { - p.Confidence++ - if p.Confidence >= p.Beta { - return true // Finalized - } - } else { - p.Confidence = 0 - } - return false -} -``` - -### 2.

Prism – Voting-Based Consensus - -Direct voting mechanism for governance: - -```go -type PrismEngine struct { - proposals map[ID]*Proposal - votes map[ID]map[NodeID]Vote - threshold float64 // e.g., 0.75 for 75% approval -} - -func (p *PrismEngine) ProcessVote(vote Vote) { - p.votes[vote.ProposalID][vote.NodeID] = vote - - if p.calculateSupport(vote.ProposalID) >= p.threshold { - p.executeProposal(vote.ProposalID) - } -} -``` - -### 6. Quasar – Quantum-Secure Overlay - -The pinnacle layer adding dual-certificate finality: - -```go -type QuasarConsensus struct { - engine ConsensusEngine // Beam or Nova - blsAgg *BLSAggregator - ringtail *RingtailThreshold - timeout time.Duration -} - -type DualCertificate struct { - BLSCert []byte // Classical BLS aggregate - RingtailCert []byte // Post-quantum threshold sig -} - -func (q *QuasarConsensus) Finalize(block Block) (*DualCertificate, error) { - // Parallel certificate collection - ch1 := make(chan []byte) - ch2 := make(chan []byte) - - go q.collectBLS(block, ch1) - go q.collectRingtail(block, ch2) - - select { - case <-time.After(q.timeout): - return nil, ErrTimeout - case blsCert := <-ch1: - rtCert := <-ch2 - return &DualCertificate{blsCert, rtCert}, nil - } -} -``` - -## Platform Management Capabilities - -As the successor to P-Chain in Lux 2.0, Q-Chain handles all platform management responsibilities with quantum-secure guarantees: - -### Validator Management -```go -type ValidatorTx struct { - NodeID string - StakeAmount uint64 - StartTime time.Time - EndTime time.Time - DelegationFee uint32 - RewardAddress Address - ProofOfStake DualSignature // BLS + Ringtail -} -``` - -### Staking Operations -- **Minimum Stake**: 2,000 LUX -- **Delegation**: Support for delegated staking with customizable fees -- **Rewards**: Automatic distribution with quantum-secure signatures -- **Slashing**: Quantum-resistant penalty mechanisms - -### chain Creation and Management -```go -type CreateChainTx struct { - Owners []Address - Threshold uint32 - ControlKeys []PublicKey - chainAuth DualCertificate - VMType string // "EVM", "WASM", "Custom" -} -``` - -### Governance Functions -- **Proposal Submission**: Quantum-signed governance proposals -- **Voting**: Weighted by stake with dual-certificate validation -- **Parameter Updates**: Network-wide configuration changes -- **Chain Registration**: New chain deployment and management - -## Core Innovation: Dual-Certificate Finality - -### The Dual-Certificate Mechanism - -Q-Chain requires two cryptographic certificates for block finality: - -1. **BLS Aggregated Signature (Classical)** - - BLS12-381 curve with 128-bit classical security - - Aggregatable signatures for efficiency - - Compatible with existing infrastructure - -2. **Ringtail Threshold Signature (Post-Quantum)** - - Lattice-based (LWE) with 128-bit post-quantum security - - Threshold scheme: no single validator holds full key - - Two-round protocol for efficiency - -```go -// Block is final IFF both certificates are valid -func IsBlockFinal(block Block, cert DualCertificate) bool { - return verifyBLS(cert.BLSCert, block) && - verifyRingtail(cert.RingtailCert, block) -} -``` - -### Security Analysis - -The dual-certificate design provides defense in depth: - -| Attack Scenario | BLS Certificate | Ringtail Certificate | Result | -|----------------|-----------------|---------------------|---------| -| Classical Attacker | Secure (128-bit) | Secure (harder) | ✅ Block Safe | -| Quantum Attacker | Vulnerable | Secure (128-bit PQ) | ✅ Block Safe | -| Implementation Bug in BLS | Compromised | Secure | ✅ Block Safe | -| Implementation Bug in Ringtail | Secure | Compromised | ✅ Block Safe | -| Both Systems Compromised | Compromised | Compromised | ❌ Block Unsafe | - -### Quantum Attack Window - -Q-Chain's rapid finality creates an impossibly narrow attack window: - -```markdown -Timeline: -T+0ms: Block proposed -T+50ms: Ringtail timeout (mainnet) -T+295ms: BLS aggregation complete -T+350ms: Block finalized - -Attack Window: < 50ms -``` - -Even with a large-scale quantum computer, breaking BLS12-381 would require: -- ~2,330 logical qubits -- Billions of sequential operations -- Far more than 50ms of computation time -

The implementation provides absolute quantum resistance by using hash-based signatures that rely only on the one-wayness of hash functions. Each Lux Safe deployment can optionally enable Lamport OTS as an additional signature type alongside ECDSA, providing a migration path to quantum safety without disrupting existing operations. - -## Motivation - -Gnosis Safe is the most battle-tested multisig wallet in the ecosystem, but it relies entirely on ECDSA signatures which will be broken by quantum computers. By extending Safe with Lamport OTS, we can: -- Provide immediate quantum resistance for high-value treasuries -- Allow gradual migration from ECDSA to quantum-safe signatures -- Maintain compatibility with existing Safe infrastructure -- Pioneer the first production quantum-safe multisig wallet - -## Specification - -### Lamport OTS Overview - -Lamport signatures use one-time key pairs where: -- Private key: 512 random 256-bit values (256 pairs) -- Public key: Hash of all private key values -- Signature: Reveal half of private key based on message hash bits -- Verification: Hash revealed values and compare to public key - -### Safe Integration Architecture - -```solidity -// SPDX-License-Identifier: LGPL-3.0-only -pragma solidity ^0.8.19;

MPC Network as "Lamport Owner" - -The Safe module has exactly ONE Lamport owner key at a time: -- On-chain stores `pkh = keccak256(abi.encodePacked(currentpub))` -- Transaction authorized if MPC network produces valid Lamport signature over: - -```solidity -// Domain-separated message binding -bytes32 m = keccak256(abi.encodePacked( - safeTxHash, // Safe transaction hash - nextPKH, // Commit to next public key - address(this), // Prevent cross-contract replay - block.chainid // Prevent cross-chain replay -)); -``` - -#### 2. Threshold Key Generation (DKG) for Lamport Secrets - -A Lamport public key consists of 256 pairs of secrets: `(sk[i][0], sk[i][1])`. - -T-Chain nodes perform DKG so that for every `sk[i][b]`: -- No single node knows the full secret -- Any `t-of-n` nodes can reconstruct it via MPC - -Public key material: -``` -pub[i][b] = H(sk[i][b]) // keccak256(sig[i]) == pub[i][bit] -pkh = keccak256(abi.encodePacked(pub)) -``` - -#### 3. Threshold Signing Flow (Production Protocol) - -**CRITICAL SECURITY RULES**: - -1. **Canonical Digest Rule** (mandatory): Every MPC node MUST locally compute `safeTxHash` from full transaction fields. **NEVER** accept a coordinator-provided hash. - -2. **1-Round Digest Agreement** (kills equivocation): Before revealing ANY Lamport material, nodes broadcast `H(m)` to each other. Proceed ONLY if ≥t nodes report the same value. This prevents the 2022 "different messages to different signers" attack. - -3. **Reconstruct Only Needed Halves**: For each bit position, the network reconstructs ONLY `sk[i][bit(m,i)]` - never both halves. - -```go -// T-Chain MPC signing protocol (production implementation) -func ThresholdLamportSign(tx *SafeTransaction, nextPKH bytes32) ([]byte, error) { - // ═══════════════════════════════════════════════════════════════════ - // STEP 1: Canonical Digest (SECURITY CRITICAL) - // ═══════════════════════════════════════════════════════════════════ - // Every node computes safeTxHash LOCALLY from full tx fields - // NEVER accept coordinator-provided hash - this prevents equivocation - safeTxHash := computeSafeTxHash( - tx.To, tx.Value, tx.Data, tx.Operation, - tx.SafeTxGas, tx.BaseGas, tx.GasPrice, - tx.GasToken, tx.RefundReceiver, tx.Nonce, - ) - - // ═══════════════════════════════════════════════════════════════════ - // STEP 2: 1-Round Digest Agreement (kills equivocation attack) - // ═══════════════════════════════════════════════════════════════════ - // Broadcast H(safeTxHash) to all nodes BEFORE revealing any Lamport material - // This prevents "different messages to different signers" attack - commitment := keccak256(safeTxHash) - - allCommitments := broadcastAndCollect(commitment) - matchCount := countMatching(allCommitments, commitment) - - if matchCount < threshold { - return nil, errors.New("digest disagreement - possible equivocation attack") - } - - // ═══════════════════════════════════════════════════════════════════ - // STEP 3: Domain-Separated Message - // ═══════════════════════════════════════════════════════════════════ - m := keccak256(abi.encodePacked( - safeTxHash, - nextPKH, - moduleAddress, - chainId, - )) - - // ═══════════════════════════════════════════════════════════════════ - // STEP 4: MPC Reconstruct Only Needed Halves - // ═══════════════════════════════════════════════════════════════════ - // For each bit of m, reconstruct ONLY sk[i][bit] - never both halves - sig := make([][]byte, 256) - for i := 0; i < 256; i++ { - bit := (m >> (255 - i)) & 1 - - // t-of-n nodes contribute shares for sk[i][bit] - shares := collectShares(i, bit) - if len(shares) < threshold { - return nil, errors.New("insufficient shares") - } - - // Lagrange interpolation to reconstruct secret - sig[i] = shamirReconstruct(shares) - } - - // ═══════════════════════════════════════════════════════════════════ - // STEP 5: Assemble Standard Lamport Signature - // ═══════════════════════════════════════════════════════════════════ - return sig, nil // bytes[256] - exactly what LamportBase.verify_u256 expects -} -``` - -**Attack Mitigations**: - -| Attack Vector | Mitigation | -|---------------|------------| -| Coordinator sends different txs to different signers | Canonical digest + 1-round agreement | -| Replay across contracts | `address(this)` in domain | -| Replay across chains | `block.chainid` in domain | -| Key reuse leak | `pkh = nextPKH` rotation | -| Single node compromise | t-of-n threshold (no single node has full secret) | - -#### 4.

Signers never deliver plaintext shares to a trusted "MPC box". Instead, they post commitments and encrypted contributions to the LUX chain (bulletin board). After ≥t participants contribute for a session, the chain finalizes a Lamport signature for a **canonical on-chain `WithdrawalIntentHash`**, which can be relayed and verified on an EVM chain with exactly one Lamport verification. - -**Key innovation**: This protocol **solves ALL known threshold Lamport attacks** from the EthResearch 2022 discussion and Vitalik's proposals: -- **Split-view/equivocation**: Canonical on-chain `WithdrawalIntentHash` from finalized state -- **Bit harvesting**: Single-use `leafIndex` with `nextPKH` rotation enforced on-chain -- **Trusted assembler**: Encrypted contributions + T-Chain 69-of-100 threshold decryption -- **Synchronicity dependence**: 2-round chain-based protocol (no N² gossip) -- **Missing accountability**: Slash-on-failure with forced plaintext reveal - -**Important correction:** the Lamport signature is a set of preimages. Those preimages necessarily become public at finalization. The security goal is that **no party learns both branches** (0/1 secrets) for a leaf unless ≥t parties collude, and that signers cannot be tricked into signing different messages for the same session. - ---- - -## Motivation - -LP-4105 defines Lamport OTS for Lux Safe but assumes a single signer. Production deployments require threshold control where: - -1. **T-of-N** parties must cooperate -2. **No trusted assembler** collects plaintext shares -3. **Anti-equivocation**: a malicious leader/block producer cannot show different messages to different signers -4. **On-chain coordination**: chain acts as bulletin board and enforces session rules -5. **Post-quantum** authorization on destination chains (hash-based) - ---- - -## Specification - -The threshold Lamport protocol consists of: -1. Setup phase for share distribution -2. Two-round signing protocol via on-chain coordination -3. Threshold decryption for signature finalization -4. Accountability mechanism for dispute resolution - -Details follow in subsequent sections. - -## Threat Model and Security Goals - -Assume an adversary can: -- control/DoS some signers, -- attempt equivocation (show different messages to different signers), -- attempt to learn enough information to forge signatures for new messages. - -### Goals - -**G1 (Anti-equivocation):** the only signable digest is derived from **finalized on-chain state**, so all honest signers necessarily bind to the same message. - -**G2 (Threshold unforgeability for a leaf):** with < t corrupt signers, the adversary cannot compute a valid Lamport signature for any message other than the one finalized by the protocol for that leaf. - -**G3 (No trusted assembler):** no single party receives all plaintext contributions; only the final Lamport signature is revealed publicly. - -**G4 (Accountability):** parties that commit but fail to contribute (or contribute garbage) can be identified and penalized. - ---- - -## Definitions and Notation - -| Symbol | Description | -|--------|-------------| -| `n` | committee size (epoch validator set or configured signer set) | -| `t` | threshold required to finalize | -| `i` | Lamport bit index (0..255) | -| `b` | bit value (0 or 1) | -| `j` | signer index / validator | -| `r[j][i][b]` | signer j's secret share for bit i, branch b (32 bytes) | -| `S[i][b]` | leaf secret preimage for bit i, branch b | -| `PK[i][b]` | Lamport public key element = `H(S[i][b])` | -| `H()` | keccak256 (or another LP-4105-approved hash) | -| `leafIndex` | Lamport leaf number (single-use) | -| `epoch` | LUX epoch that defines committee membership | -| `PKH` | hash commitment to the Lamport public key (`H(PK[...])`) | - ---- - -## Canonical Message to Sign (required) - -To prevent "different message per signer" attacks, the signable digest MUST be derived from a finalized on-chain withdrawal intent: - -```solidity -WithdrawalIntentHash = keccak256(abi.encode( - bytes32("LUX-WITHDRAW-V1"), - srcChainId, - dstChainId, - burnTxHash, - burnLogIndex, - token, - amount, - recipient, - nonce, - epoch, - leafIndex, - nextPKH -)); -``` - -- `epoch`, `leafIndex`, `nextPKH` are enforced by the LUX contract. -- No signer signs an off-chain "txHash" or leader-proposed blob. - ---- - -## Setup Phase (per leaf) - -Each Lamport leaf has secrets: - -``` -S[i][b] = Σ_j r[j][i][b] mod 2^256 -PK[i][b] = H(S[i][b]) -``` - -Each signer j samples `r[j][i][b] ← random(32 bytes)` for all i,b and stores only their own shares. - -### Publishing PKH (required) - -The system MUST publish a commitment to the Lamport public key (or a Merkle/XMSS root committing to many leaves). Two acceptable approaches: - -**Option A (practical, small committees):** MPC ceremony among signers to compute `PK[i][b]` (or PKH) without revealing `S[i][b]`. - -**Option B (chain-coordinated):** signers post commitments to their shares and the protocol includes an audit/dispute mechanism; publication may reveal some data if disputes occur. - -This LP standardizes signing/finalization; key-generation ceremony details may be specified in an accompanying implementation note. - ---- - -## Protocol (2 rounds on LUX chain) - -The protocol is implemented by a LUX contract (the "Coordinator" in the on-chain sense, not a trusted party). Any account can relay transactions; the contract enforces correctness. - -### Session Creation - -A session is created for a specific `WithdrawalIntentHash`: - -```solidity -sessionId = keccak256(abi.encode( - bytes32("LUX-LAMPORT-SESSION-V1"), - WithdrawalIntentHash -)); -``` - -The contract verifies the referenced withdrawal intent exists and is finalized. - -### Round 1 — Commit (bind signer + bind session) - -Each signer j submits: - -``` -commit_j = H( - bytes32("LUX-LAMPORT-COMMIT-V1") || - sessionId || - epoch || leafIndex || - WithdrawalIntentHash || - sharesRoot_j || - nonce_j -) -``` - -Where: -- `sharesRoot_j = H( r[j][*][*] for this leaf )` or a Merkle root over `(i,b)→H(r[j][i][b])` -- `nonce_j` is signer-chosen randomness - -**Contract rules:** -- Accept commits only from the epoch committee. -- Lock the participant set when ≥t commits are posted (or at a deadline). -- Require a bond per signer to deter DoS. - -### Round 2 — Contribute (message-dependent, encrypted) - -Let `b_i = bit(WithdrawalIntentHash, i)`. - -Each signer j posts ciphertexts: - -``` -ct_j[i] = ENC_to_committee( r[j][i][b_i], sessionId, i ) -``` - -**Requirements:** -- Ciphertexts MUST be addressed to a decryption committee corresponding to the epoch (e.g., threshold decryption key held by validators). -- Plaintext shares MUST NOT be posted unless in a dispute. - -### Finalization — Threshold Reveal of the Lamport signature - -When the contract has ≥t valid contributions for all 256 bits, the committee performs threshold decryption/reveal and publishes: - -``` -sig[i] = Σ_j r[j][i][b_i] mod 2^256 -Signature = sig[0..255] -``` - -### T-Chain Integration (LP-7000, LP-7330) - -The threshold decryption/reveal is performed by the T-Chain (Threshold Chain) validator set: - -| Parameter | Value | -|-----------|-------| -| Threshold | **69-of-100** validators | -| VM | ThresholdVM (LP-7330) | -| Decryption Protocol | CGGMP21 / Ringtail | -| Consensus | Quasar with threshold finality | - -**Decryption flow:** -1. T-Chain validators receive encrypted contributions `ct_j[i]` -2. Each validator holds a share of the epoch decryption key -3. When 69+ validators provide decryption shares, the plaintext `r[j][i][b_i]` is reconstructed -4. Aggregated signature `sig[i]` is computed and emitted on-chain - -**Implementation reference:** `github.com/luxfi/node/vms/thresholdvm` - -The contract then emits: - -```solidity -event SignatureFinalized( - bytes32 indexed sessionId, - bytes32 indexed WithdrawalIntentHash, - uint256 epoch, - uint256 leafIndex, - bytes32 nextPKH, - bytes32[256] sig, - bytes32 signersBitmap -); -``` - -**Lamport verification condition (LP-4105 compatible):** - -``` -∀i: H(sig[i]) == PK[i][b_i] -``` - ---- - -## Accountability (required) - -Encrypted contributions can be garbage. The protocol MUST include an enforceable mechanism to punish non-cooperative or dishonest signers. - -### A) Slash-on-failure with forced plaintext reveal (recommended default) - -If finalization fails (missing bits / invalid signature / decryption failure), the contract opens a dispute window. - -For any failing index i, a signer j can reveal: -- plaintext `r[j][i][b_i]` -- opening data proving it matches `sharesRoot_j` (Merkle branch or precommitted hash) -- the nonce/opening that binds to `commit_j` - -The contract verifies the reveal against `commit_j` material and: -- slashes signers who did not contribute, or -- slashes signers whose ciphertext cannot correspond to a valid committed share. - -This is slow but implementable and enforceable. - -### B) ZK proof of well-formed encryption (optional) - -Each `ct_j[i]` includes a proof that it encrypts a 32-byte value consistent with `sharesRoot_j`. This reduces disputes but increases complexity. - ---- - -## Key Rotation (required) - -Lamport leaves are one-time. Each finalized signature commits to `nextPKH`. - -**Rules:** -- `leafIndex` MUST be single-use and monotonically increasing. -- On finalization, the LUX contract updates `currentPKH = nextPKH` atomically. -- Destination chain enforces the same rotation when verifying a withdrawal. - -**Recommended:** use an XMSS/Merkle root committing to many Lamport leaves so destination stores one root and each withdrawal carries a Merkle proof for the leaf. - ---- - -## Message Format for Safe / Bridge Use - -This LP does not sign arbitrary Safe tx bytes. It signs the canonical on-chain intent hash (anti-equivocation). - -If integrating with Safe, the Safe module's "action" MUST be embedded into the intent (e.g., recipient/module/amount fields), and the intent hash is what gets signed. - ---- - -## Rationale - -- "No node ever reconstructs a Lamport preimage" is false if interpreted literally: the final Lamport signature is itself a set of preimages. The correct claim is: no single party learns both branch secrets for the leaf, and no trusted party receives all plaintext inputs. -- The canonical intent hash is the decisive fix for the classic "leader sends different messages to different signers" attack. -- Large validator sets should treat encryption/decryption as epoch infrastructure; small signer sets can run the same protocol off-chain (still 2 rounds) without posting ciphertexts on-chain. - ---- - -## Backwards Compatibility - -This protocol produces **standard Lamport signatures** as defined in LP-4105. The on-chain verifier is unchanged: - -```solidity -// Same verification as single-signer Lamport -LamportLib.verify(message, signature, publicKey) -``` - -Only the off-chain signing process differs. - ---- - -## Test Cases - -### Test 1: 2-of-3 Signing - -```yaml -Setup: - - 3 signers generate independent shares - - Public key computed via MPC - -Signing: - - Two signers commit - - Two signers contribute - - Signature finalized via threshold reveal - -Verification: - - Standard Lamport verify on EVM with LP-4105 verifier returns true -``` - -### Test 2: DoS - Missing Contribution - -```yaml -Setup: - - Signer commits but doesn't contribute - -Expected: - - Timeout triggers dispute window - - Non-contributing signer slashed after timeout - - Remaining signers can restart if ≥ t -``` - -### Test 3: Garbage Contribution - -```yaml -Setup: - - Signer contributes malformed ciphertext - -Expected: - - Dispute reveal proves mismatch - - Signer slashed - - Session can restart with honest signers -``` - -### Test 4: Equivocation Attempt - -```yaml -Setup: - - Attacker attempts to show different messages to different signers - -Expected: - - Impossible: signers only sign WithdrawalIntentHash derived from finalized on-chain state - - No off-chain message proposal accepted -``` - ---- - -## Security Considerations - -### Preimage Revelation - -The final Lamport signature is a set of preimages—these necessarily become public. The security goal is that: -1. No party learns **both** branch secrets (0/1) for any leaf position unless ≥t parties collude -2. Signers cannot be tricked into signing different messages for the same session - -### Complete Resolution of Vitalik/EthResearch Threshold Lamport Critiques - -LP-4106 addresses **all known attacks** from the 2022 EthResearch discussion and Vitalik's "8-choice Lamport" proposal: - -| Attack | Description | LP-4106 Defense | Status | -|--------|-------------|-----------------|--------| -| **Split-View / Equivocation** | Malicious BP shows different messages to different signers | Canonical on-chain `WithdrawalIntentHash` - signers derive message from finalized state only | ✅ SOLVED | -| **Bit Harvesting Across Sessions** | Attacker learns one branch per bit across multiple sessions | `leafIndex` is single-use + monotonic; `nextPKH` enforced on-chain; cannot reuse leaves | ✅ SOLVED | -| **8-Choice Slippage Attack** | Vitalik's compression variant vulnerable to partial revelation | We use standard 256-bit Lamport (not 8-choice); each bit independent | ✅ N/A | -| **Trusted Assembler** | Central party receives all plaintext shares | No assembler; encrypted contributions + T-Chain threshold decryption (69-of-100) | ✅ SOLVED | -| **Synchronicity Dependence** | Requires N² gossip for signers to agree on message | 2-round protocol via chain bulletin board; no signer-to-signer communication | ✅ SOLVED | -| **Missing Accountability** | No way to punish non-cooperative signers | Slash-on-failure with forced plaintext reveal; bonds required | ✅ SOLVED | -| **Replay / Double-Spend** | Same signature used for multiple withdrawals | `(epoch, leafIndex, nonce)` tuple uniquely identifies session; contract enforces single-use | ✅ SOLVED | - ---- - -### Defense Against Split-View / Equivocation Attack (EthResearch 2022) - -The 2022 EthResearch critique of threshold Lamport describes a **split-view / equivocation attack**: - -> Each signer reveals only the portion of the Lamport material they're responsible for. A malicious block producer can craft different valid messages B_i and send a different one to each signer such that the particular query bits that signer will reveal match the attacker's target digest H'. The attacker aggregates the returned openings and ends up with a "valid-enough" signature for H' without any signer ever seeing H'. - -**Root cause**: The scheme assumes "everyone is signing the same hash" but does not enforce it. Security depends on synchrony / signers gossiping the hash. - -#### How LP-4106 Solves This Attack - -LP-4106 fixes this class of attacks by moving message agreement from "signers talking to each other" to "signers talking to a single canonical bulletin board with finality": - -##### 1. The Signable Digest is NOT Leader-Proposed - -Signers do **not** sign "a block / tx hash someone sent me". They sign exactly: - -``` -WithdrawalIntentHash = keccak256(abi.encode(... finalized on-chain fields ...)) -``` - -The contract only allows sessions for intents that **exist and are finalized**. This means: -- There is exactly **one canonical message** per intent, derived from chain state -- A malicious relayer/BP cannot give signer A one message and signer B another while still calling it "the same session" - -##### 2. Sessions Bind Everyone to the Same Hash - -``` -sessionId = H("LUX-LAMPORT-SESSION-V1", WithdrawalIntentHash) -``` - -Round 1 commits include `sessionId` and `WithdrawalIntentHash`. Once the contract locks the participant set, "the thing being signed" is **objectively fixed in public state**. - -The "send different blocks to different signers" move becomes irrelevant: signers are not signing an off-chain proposal; they are signing the chain-finalized intent hash. - -##### 3. The Chain is the Anti-Equivocation Communication Channel - -The critique says: "solved if signers talk to each other to ensure they see the same hash". - -LP-4106's answer: they don't need to talk to each other; they only need to: -1. **Read finalized state** from the chain -2. **Post commits/contributions** to the chain - -The chain provides: -- A **single agreed transcript** (bulletin board) -- A **single message** (intent hash) enforced by consensus + contract rules - -#### Attack Failure Analysis - -Map the attacker's steps to this protocol: - -| Attack Vector | LP-4106 Defense | -|---------------|-----------------| -| **Show signer i a different message off-chain** | Signer ignores it. The signer computes `WithdrawalIntentHash` from finalized on-chain intent fields (or directly from contract storage/events). The contract enforces that the session is tied to that hash. **No "per-signer message" surface.** | -| **Create multiple different intents (one per signer)** | Then there are multiple different sessions with different `sessionIds`. Commit format binds `commit_j` to `sessionId` and `WithdrawalIntentHash`. Contributions are bound to `sessionId`. The attacker **can't mix and match** partial openings from different sessions to form a signature for a single target hash. | -| **Reuse the same one-time leaf across sessions** | `leafIndex` is single-use + monotonic and contract-enforced rotation via `nextPKH`. Prevents "harvest openings across multiple sessions until enough is learned". | - -#### The Coordination Guarantee - -LP-4106 makes the scheme secure by changing the assumption from "signers are synchronous / gossip hashes" to: - -> **Finality / common-view assumption for the Lux chain**: Honest signers derive the signable digest **only** from finalized on-chain state. - -This is the right place to put the assumption, because it's already required for any bridge/safe authorization.

They provide a cryptographic guarantee that data has been made available to the network. The current DA certificates rely on BLS signatures, which are efficient to aggregate but are not secure against future quantum computers. - -To ensure the long-term integrity and security of the LuxDA Bus, it is essential to transition to post-quantum secure signature schemes for DA certificates. This LP specifies a hybrid approach that combines the efficiency of BLS signatures with the quantum resistance of ML-DSA. This allows for a gradual and secure migration to full post-quantum security, protecting the network from the threat of "harvest now, decrypt later" attacks on the DA layer. - -## Backwards Compatibility - -This LP is designed with a phased migration strategy to ensure backwards compatibility and a smooth transition across the network. - -- **Phase 1 (Classical)**: Existing nodes continue to use the current BLS-based DA certificates. -- **Phase 2 (Hybrid)**: Upgraded nodes will produce and verify hybrid certificates containing both BLS and ML-DSA signatures. These nodes can still verify classical certificates from non-upgraded nodes. A lower threshold for PQ signatures can be used during the transition to accommodate partial network upgrades. -- **Phase 3 (Full PQ)**: Once the network has fully upgraded, the BLS signatures will be deprecated, and only ML-DSA signatures will be required. - -This phased rollout ensures that the network remains operational and secure throughout the entire migration process, with no breaking changes for applications relying on the DA layer. -## Security Considerations - - -1. **Threshold security**: Both BLS and PQ thresholds must be met in hybrid mode -2. **Committee binding**: Public keys bound to registered stake -3. **Challenge mechanism**: Invalid certificates can be challenged -4. **Key compromise**: PQ keys protect against future quantum attacks on BLS -5. **Size vs security**: Larger certificates trade bandwidth for quantum resistance - -## Test Plan - -1.

Dilithium as Primary PQC Scheme**: CRYSTALS-Dilithium (ML-DSA) was selected over alternatives due to: -- NIST standardization (FIPS 204) providing regulatory certainty -- Fastest verification among lattice-based signatures (0.5ms) -- Reasonable signature size (3,293 bytes) compared to hash-based schemes -- Strong security proofs based on Module-LWE hardness - -**2. Hybrid Migration Strategy**: The phased BLS+Ringtail hybrid approach was chosen over immediate replacement because: -- Allows gradual validator migration without hard fork -- Maintains backward compatibility during transition -- Provides defense-in-depth (both schemes must be broken) -- Enables testing and optimization before full commitment - -**3. Lattice-Based Threshold Signatures**: Traditional threshold schemes (Shamir, BLS) are quantum-vulnerable: -- Threshold Dilithium preserves t-of-n security model -- No trusted dealer requirement (distributed key generation) -- Same verification as standard Dilithium (interoperability) - -**4. Signature Aggregation**: To mitigate bandwidth overhead: -- Batch verification reduces CPU cost by ~80% for bulk operations -- Aggregate signatures combine multiple signatures into smaller proofs -- Compression techniques reduce signature size by ~45% - -### Alternatives Considered - -- **SPHINCS+**: Hash-based signatures with 256-bit quantum security, but signature sizes (17KB+) and signing time (180ms) make it impractical for consensus. Reserved for checkpoint finality only. -- **Falcon**: Faster than Dilithium but requires complex floating-point operations and has side-channel concerns. Not NIST-standardized as primary. -- **Rainbow**: Multivariate signatures rejected due to cryptanalysis concerns that led to NIST removal. -- **Direct Replacement**: Immediate ECDSA deprecation rejected as too disruptive to existing infrastructure and validators. - -## Backwards Compatibility - -This LP introduces significant but managed breaking changes: - -### Transition Period - -**Phase 1 - Hybrid Mode (2025-2027)**: -- Validators MAY use either ECDSA or Dilithium signatures -- Consensus accepts both signature types -- No breaking changes for existing infrastructure -- New validators encouraged to use Dilithium - -**Phase 2 - Dilithium Primary (2027-2030)**: -- Dilithium signatures REQUIRED for new validators -- ECDSA signatures OPTIONAL for legacy validators -- SDK updates for Dilithium support mandatory -- Wallet providers must implement Dilithium signing - -**Phase 3 - ECDSA Deprecated (2030+)**: -- Pure Dilithium consensus -- ECDSA-only validators cannot participate -- Legacy transactions remain valid but cannot be created - -### Migration Requirements - -**Validators**: -- Generate Dilithium key pair via `lux quantum keygen` -- Update configuration to enable hybrid mode -- Transition to Dilithium-only after testing - -**Applications**: -- Update SDK to version with Dilithium support -- Handle larger signature sizes in transaction parsing -- Implement dual-verification during hybrid period - -**Bridges**: -- Upgrade threshold signatures to lattice-based schemes -- Update light client proof verification -- Maintain ECDSA verification for historical proofs - -## Security Considerations - -### Quantum Threat Model - -**Adversary Capabilities**: -- Access to large-scale quantum computer (10,000+ logical qubits) -- Can run Shor's algorithm (breaks ECDSA in O(n³) time) -- Can run Grover's algorithm (2× speedup on hash collisions) -

-## Migration Path - -### Phase 1: Validator Support (Q1 2026) -- Add ML-DSA public keys to validator registration -- Hybrid BLS + ML-DSA signing in consensus -- Gradual weight shift from BLS to ML-DSA - -### Phase 2: Transaction Support (Q2 2026) -- Deploy ML-DSA precompile to C-Chain -- Enable ML-DSA transaction signing -- Wallet integration for quantum-safe addresses - -### Phase 3: Full Transition (Q3 2026) -- ML-DSA becomes primary signature scheme -- BLS maintained for backwards compatibility -- New validators require ML-DSA keys - -## Security Considerations - -### Quantum Resistance - -**Lattice Security**: Based on MLWE problem -- No known quantum algorithms break lattice problems efficiently -- NIST analyzed security for 6+ years before standardization -- Conservative parameter selection (128/192/256-bit security) - -**Long-term Security**: -- Public keys captured today remain secure post-quantum -- Deterministic signatures prevent timing attacks -- Constant-time implementation in CIRCL library - -### Side-Channel Resistance - -**Constant-Time Operations**: -- All arithmetic operations run in constant time -- No secret-dependent branches -- No secret-dependent memory access - -**Implementation Quality**: -- CIRCL library used by Cloudflare in production -- Formal verification of critical components -- Regular security audits - -### Key Management - -**Validator Keys**: -- Generate fresh ML-DSA keys for each validator -- Store private keys in HSM when available -- Use separate keys for consensus vs transaction signing - -**Backup & Recovery**: -- ML-DSA private keys are 4,000 bytes (65% larger than ECDSA) -- Use seed-based key derivation (BIP-39 compatible) -- Encrypt backups with quantum-safe encryption (AES-256) - -## Backwards Compatibility - -**Hybrid Period (2026-2027)**: -- All validators support BOTH BLS and ML-DSA -- Transactions can use either ECDSA or ML-DSA -- Consensus requires both signature types to be valid - -**Legacy Support**: -- ECDSA addresses continue to function -- Cross-chain messaging supports both signature types -- Gradual deprecation of ECDSA over 2-3 years - -## Rationale - -### Why ML-DSA over alternatives? - -**vs SLH-DSA (LP-312)**: -- ML-DSA is 10-100x faster (417μs vs 40ms sign time) -- Smaller signatures (3,309 bytes vs 17,088-49,856 bytes) -- Trade-off: Lattice security assumptions vs hash-based conservative security - -**vs Classical Multivariate**: -- ML-DSA has stronger security analysis -- NIST standardized (vs academic proposals) -- Better performance and key sizes - -**vs Falcon (NIST finalist)**: -- ML-DSA has simpler implementation (no floating point) -- More conservative security parameters -- Deterministic signing (Falcon requires random seeds) - -### Why ML-DSA-65 as default? - -**192-bit Security (NIST Level 3)**: -- Exceeds Bitcoin's 128-bit security -- Margin for future cryptanalysis advances -- Matches high-value financial applications - -**Performance Balance**: -- 417μs sign time acceptable for transaction throughput -- 108μs verify time suitable for consensus -- 3,309 byte signatures fit in typical network packets - -## Reference Implementation -

-**Backup & Recovery**: -- SLH-DSA private keys are only 64-128 bytes -- Smaller than ML-DSA keys (4,000 bytes) -- Standard seed-based derivation (BIP-39 compatible) -- Encrypt backups with AES-256 - -## Backwards Compatibility - -**Hybrid Period (2026-2027)**: -- Validators support ML-DSA, SLH-DSA, or both -- Critical operations gradually require SLH-DSA -- Governance proposals support both signature types - -**Legacy Support**: -- ECDSA addresses continue to function -- BLS signatures maintained for consensus -- Gradual transition based on security requirements - -## Rationale - -### Why SLH-DSA over other hash-based schemes? - -**vs XMSS/LMS (stateful)**: -- SLH-DSA is stateless (no state management) -- No risk of key compromise from state loss -- Simpler operational model -- Better for distributed systems - -**vs ML-DSA (lattice-based)**: -- SLH-DSA has more conservative security foundation -- No mathematical assumptions beyond hash functions -- Resistant to future cryptanalytic breakthroughs -- Trade-off: Much larger signatures and slower signing - -**vs Classical Hash Functions**: -- SLH-DSA provides signatures (authentication) -- Hash functions alone only provide integrity -- Merkle tree structure enables efficient verification - -### Why SHA2-128f as default? - -**128-bit Security**: -- Matches current blockchain security standards -- Adequate for most applications -- Future-proof against quantum attacks - -**Fast Signing (f variant)**: -- 10ms signing time acceptable for transactions -- 2x larger signature (17KB vs 7.8KB) acceptable -- Better user experience vs small variants (309ms) - -**SHA2 vs SHAKE**: -- SHA2 has longer history (since 2001) -- Better hardware support and optimization -- SHAKE variants 3-5x slower on current hardware - -### When to use which variant? - -**SHA2-128f (Default)**: -- Standard transactions -- Regular validator operations -- General-purpose signing - -**SHA2-256s (Maximum Security)**: -- Root CA certificates -- Genesis block signatures -- 10+ year security requirements -- Accept 603ms signing time for ultimate security - -**SHA2-192f (Balanced)**: -- High-value transactions -- Important governance proposals -- Balance between security and performance -

Environmental integrity is measured against baselines and verified over time; social benefit is defined by economic mobility, access, and resilience; and governance is enforced through on-chain auditability with privacy-preserving controls. Lux provides capital and financial rails, Hanzo builds and verifies high-impact technology, Zoo anchors life-first mission and ethics, and our DAOs steward community ownership of IP so long-tail value accrues to contributors and communities. The result is a thoughtfully designed flywheel where transparency builds trust, trust attracts capital, and capital scales verified outcomes. + +## Specification + +This LP serves as a meta-framework defining investment policies. The specification is embodied in: + +1. **Core Values** (Section above) - Non-negotiable principles +2. **ESG Pillars** - Environmental, Social, and Governance definitions +3. **Investment Process** - Five-stage workflow from intake to scale +4. **Enforcement Mechanisms** - Outcome-gated capital, claims registry, verification + +Detailed specifications for each pillar are defined in subsidiary LPs (LP-751, LP-752, LP-753). + +## Rationale + +The framework design reflects several key decisions: + +1. **Tranched capital over lump-sum** - Reduces risk of misuse and creates accountability checkpoints +2. **Claims registry with evidence hashes** - Enables third-party verification without exposing sensitive data +3. **Privacy-preserving verification** - Balances transparency with data protection using ZK proofs +4. **Ecosystem role separation** - Clear boundaries prevent conflicts of interest and enable specialization +5. **Binding covenants over voluntary guidelines** - Legal enforcement mechanisms complement on-chain accountability + +## Backwards Compatibility + +This LP establishes a new framework and does not modify existing investment structures. Existing investments may be evaluated against this framework but are not retroactively bound by it. + +## Security Considerations + +1. **Evidence tampering** - Mitigated through immutable on-chain hashes and third-party attestations +2. **Verifier collusion** - Multiple independent verifiers required for material claims +3. **Privacy leakage** - ZK proofs and aggregated statistics prevent individual data exposure +4. **Governance capture** - DAO voting mechanisms include anti-concentration measures + +## Test Cases + +As a Meta LP, formal test cases are not applicable. Framework validation is demonstrated through: + +1. Successful application to pilot investments +2. Third-party audit of claims registry integrity +3. LP and stakeholder satisfaction surveys +4.

As the finance layer of the Lux-Hanzo-Zoo ecosystem, we deploy capital only to ESG-aligned opportunities, with environmental integrity measured against baselines, social benefit defined by economic mobility and resilience, and governance enforced through on-chain accountability. Our infrastructure enables low-cost, transparent financial access globally, while our investment vehicles hard-code impact covenants into funding terms. The result is a flywheel where proof builds trust, trust attracts capital, and capital scales verified outcomes—creating a compounding system where everyone benefits, not just capital. + +## Changelog + +| Version | Date | Changes | +|---------|------|---------| +| 1.0 | 2025-12-17 | Initial draft | + +## Copyright + +Copyright and related rights waived via [CC0](https://creativecommons.org/publicdomain/zero/1.0/). diff --git a/LPs/lp-2920-esg-principles-and-commitments.md b/LPs/lp-2920-esg-principles-and-commitments.md new file mode 100644 index 00000000..8b2ac969 --- /dev/null +++ b/LPs/lp-2920-esg-principles-and-commitments.md @@ -0,0 +1,199 @@ +--- +lp: 2920 +title: ESG Principles and Commitments +tags: [esg, sustainability] +description: Foundational ESG framework defining Lux Network's environmental, social, and governance commitments. +author: Lux Network Team (@luxfi) +discussions-to: https://github.com/luxfi/lps/discussions +status: Draft +type: Meta +created: 2025-12-16 +order: 2920 +--- + +# LP-800: ESG Principles and Commitments + +## Abstract + +This LP establishes the foundational Environmental, Social, and Governance (ESG) framework for Lux Network.

This is safe for: -- **Correlated assets**: ETH/LETH maintain 1:1 peg via arbitrage -- **Self-repaying**: Yield reduces debt before liquidation -- **No interest**: Unlike traditional lending, debt doesn't grow - -For uncorrelated assets, standard LTV ratios (70-80%) should apply. - -## Related Standards - -| LP | Title | Relationship | -|----|-------|--------------| -| LP-3000 | Standard Library Registry | Master registry | -| LP-3004 | Teleport Protocol | Cross-chain bridge | -| LP-3020 | LRC-20 Token Standard | Base token interface | -| LP-6022 | Warp Messaging 2.0 | Cross-chain messaging | -| LP-9072 | Bridged Asset Standard | Bridge token pattern | - -## Backwards Compatibility - -This LP supersedes the previous s* synthetic token model.

A security token on Lux is a regulated ERC-20 with embedded compliance enforcement at the transfer layer. The on-chain token contract IS the cap table. The on-chain compliance registry IS the KYC/AML gate. Every transfer, every dividend payment, every corporate action is a verifiable on-chain transaction with an immutable audit trail. - -Lux operates the full regulated stack: Alternative Trading System (ATS), Broker-Dealer (BD), and Transfer Agent (TA). The on-chain contracts are the execution layer for all three. - -## Motivation - -Traditional securities infrastructure relies on: -- Paper cap tables maintained by transfer agents (Computershare, AST) -- Settlement via DTCC with T+1 (formerly T+2) delays -- Reconciliation across multiple intermediaries who each maintain separate ledgers -- Restricted secondary trading through closed systems with limited interoperability - -Digital securities on Lux collapse the entire stack into on-chain primitives: -- `SecurityToken.balanceOf()` replaces the shareholder registry -- `ComplianceRegistry.canTransfer()` replaces manual compliance checks -- `DividendDistributor.claim()` replaces paper dividend warrants -- Settlement is atomic and final within 1ms (Lux consensus finality) - -The result: 24/7 trading, instant settlement, automated compliance, and a single source of truth. - -## Standards Compatibility - -### ERC-1404: Simple Restricted Token - -The base standard. Every SecurityToken implements ERC-1404, which adds two functions to ERC-20: - -```solidity -function detectTransferRestriction(address from, address to, uint256 value) - external view returns (uint8 restrictionCode); - -function messageForTransferRestriction(uint8 restrictionCode) - external view returns (string memory message); -``` - -Callers check restrictions before submitting a transfer. Wallets and DEXs use this to display human-readable rejection reasons. - -### ERC-3643 (T-REX): Institutional Compliance - -ERC-3643 defines the Token for Regulated EXchanges framework. Lux implements the core T-REX concepts through its modular compliance architecture: - -| T-REX Concept | Lux Implementation | -|---|---| -| Identity Registry | ComplianceRegistry (whitelist + KYC status) | -| Identity Verification | Off-chain KYC via Hanzo IAM, on-chain attestation | -| Compliance Modules | IComplianceModule interface, pluggable into registry | -| Claim Topics | accreditationStatus field (0=none, 1=accredited, 2=QIB) | -| Trusted Issuers | COMPLIANCE_ROLE holders | - -The ComplianceRegistry supports an ordered chain of IComplianceModule implementations.

Compliance bypass on mint/burn: By design, minting and burning bypass compliance. This is intentional -- the issuer must be able to issue and redeem. The MINTER_ROLE controls who can do this. -4.

Use sparingly -- a paused security token blocks all trading. -6. Forced transfers: CorporateActions.forcedTransfer() bypasses compliance. This is required for regulatory seizure (court orders, sanctions). Access must be tightly controlled. -7. Secrets: All API keys, webhook secrets, and signing keys are stored in KMS (kms.hanzo.ai).

The same DEX binary operates in two modes: unregulated (permissionless, any ERC-20) and regulated (compliance-enforced, security tokens). The difference is configuration -- whether a pool has a ComplianceHook attached. - -## Motivation - -Security tokens cannot trade on permissionless DEXs. Every swap involving a security token is a transfer that must pass compliance checks (KYC, accreditation, jurisdiction, lockup). Without enforcement at the DEX layer, an investor could bypass compliance by swapping through a pool instead of calling `transfer()` directly. - -The Uniswap V4 hooks architecture solves this cleanly. A hook contract executes before and/or after each swap, providing a natural enforcement point. Lux implements this as a native precompile hook, not a Solidity contract, for gas efficiency and tamper resistance. - -## Design Principles - -1. **Same binary, different config.** The DEX precompile is one piece of software. A pool with no hook is permissionless. A pool with `ComplianceHook` is regulated. No code fork. -2. **Compliance at the pool level.** Each pool independently decides its compliance posture. A USDC/ETH pool is permissionless. An ACME-SHARES/USDC pool has `ComplianceHook`. -3. **No new compliance logic.** `ComplianceHook` delegates entirely to `ComplianceRegistry`. The same compliance rules that govern direct `transfer()` govern DEX swaps. -4. **Fail closed.** If the compliance check reverts or returns false, the swap reverts. There is no fallback, no degraded mode. - -## Hook Architecture - -### V4 Hook Lifecycle - -The Lux DEX precompile (LP-9010) implements the Uniswap V4 PoolManager pattern with the following hook points: - -``` -beforeInitialize -> afterInitialize -beforeAddLiquidity -> afterAddLiquidity -beforeRemoveLiquidity -> afterRemoveLiquidity -beforeSwap -> afterSwap -beforeDonate -> afterDonate -``` - -`ComplianceHook` uses: -- `beforeSwap` -- validate that both counterparties pass compliance before the swap executes -- `afterSwap` -- post-trade reporting (emit events for off-chain surveillance) -- `beforeAddLiquidity` -- validate LP provider is whitelisted (for regulated pools) -- `beforeRemoveLiquidity` -- validate LP provider is still in good standing - -### ComplianceHook Interface - -```solidity -// SPDX-License-Identifier: MIT -pragma solidity ^0.8.24; - -import {IHooks} from "@luxfi/dex/interfaces/IHooks.sol"; -import {PoolKey} from "@luxfi/dex/types/PoolKey.sol"; -import {BalanceDelta} from "@luxfi/dex/types/BalanceDelta.sol"; -import {BeforeSwapDelta} from "@luxfi/dex/types/BeforeSwapDelta.sol"; -import {ComplianceRegistry} from "@luxfi/standard/securities/compliance/ComplianceRegistry.sol"; - -contract ComplianceHook is IHooks { - ComplianceRegistry public immutable REGISTRY; - - error SwapRestricted(address account, uint8 restrictionCode); - error LiquidityRestricted(address account, uint8 restrictionCode); - - constructor(ComplianceRegistry _registry) { - REGISTRY = _registry; - } - - function beforeSwap( - address sender, - PoolKey calldata key, - IPoolManager.SwapParams calldata params, - bytes calldata hookData - ) external returns (bytes4, BeforeSwapDelta, uint24) { - // Decode the actual trader (sender may be a router) - address trader = hookData.length >= 20 - ? abi.decode(hookData, (address)) - : sender; - - // Check compliance for the trader - (bool allowed, uint8 code) = REGISTRY.canTransfer( - trader, // from - trader, // to (self, for swap eligibility) - 0 // amount not relevant for eligibility - ); - if (!allowed) revert SwapRestricted(trader, code); - - return (IHooks.beforeSwap.selector, BeforeSwapDelta(0, 0), 0); - } - - function afterSwap( - address sender, - PoolKey calldata key, - IPoolManager.SwapParams calldata params, - BalanceDelta delta, - bytes calldata hookData - ) external returns (bytes4, int128) { - // Post-trade event for surveillance - // (implementation emits TradeExecuted event) - return (IHooks.afterSwap.selector, 0); - } - - function beforeAddLiquidity( - address sender, - PoolKey calldata key, - IPoolManager.ModifyLiquidityParams calldata params, - bytes calldata hookData - ) external returns (bytes4) { - address provider = hookData.length >= 20 - ? abi.decode(hookData, (address)) - : sender; - - (bool allowed, uint8 code) = REGISTRY.canTransfer(provider, provider, 0); - if (!allowed) revert LiquidityRestricted(provider, code); - - return (IHooks.beforeAddLiquidity.selector); - } -} -``` - -### Address Prefix Pattern - -Uniswap V4 uses the hook contract address to determine which hook functions are active. The leading bytes of the address encode permissions as flags. - -For compliance hooks, the canonical address prefix is: - -``` -0x07D4............................................ -``` - -The `0x07D4` prefix encodes the following permission flags: - -| Bit | Permission | Enabled | -|-----|-----------|---------| -| 0 | beforeInitialize | No | -| 1 | afterInitialize | No | -| 2 | beforeAddLiquidity | Yes | -| 3 | afterAddLiquidity | No | -| 4 | beforeRemoveLiquidity | Yes | -| 5 | afterRemoveLiquidity | No | -| 6 | beforeSwap | Yes | -| 7 | afterSwap | Yes | -| 8 | beforeDonate | No | -| 9 | afterDonate | No | - -`0x07D4` = `0000 0111 1101 0100` -- enabling beforeAddLiquidity, beforeRemoveLiquidity, beforeSwap, and afterSwap. - -Hook deployment uses `CREATE2` with a salt mined to produce an address starting with `0x07D4`. The mining process: - -```solidity -bytes32 salt = keccak256(abi.encodePacked(deployer, nonce)); -address hook = CREATE2(salt, type(ComplianceHook).creationCode, abi.encode(registry)); -require(uint160(hook) >> 148 == 0x07D4); // verify prefix -``` - -### Pool Configuration - -When creating a regulated pool: - -```solidity -PoolKey memory key = PoolKey({ - currency0: Currency.wrap(address(securityToken)), - currency1: Currency.wrap(address(usdc)), - fee: 3000, // 0.3% fee tier - tickSpacing: 60, - hooks: IHooks(complianceHook) // compliance hook address (0x07D4...) -}); - -poolManager.initialize(key, sqrtPriceX96); -``` - -When creating an unregulated pool, simply omit the hook or use a different hook: - -```solidity -PoolKey memory key = PoolKey({ - currency0: Currency.wrap(address(tokenA)), - currency1: Currency.wrap(address(tokenB)), - fee: 3000, - tickSpacing: 60, - hooks: IHooks(address(0)) // no hook -- permissionless -}); -``` - -## Regulated vs Unregulated DEX - -### Same Binary, Different Config - -The Lux DEX precompile (LP-9010) does not distinguish between "regulated mode" and "unregulated mode" at the protocol level. The distinction is per-pool: - -| Pool Type | Hook | Behavior | -|---|---|---| -| Permissionless | `address(0)` or utility hook | Any address can trade | -| Regulated | `ComplianceHook` at `0x07D4...` | Only whitelisted addresses can trade | -| Mixed fee | `DynamicFeeHook` | Custom fee logic | - -This means a single DEX deployment serves both regulated and unregulated markets. No separate infrastructure. No separate liquidity. - -### What This Enables - -1. **Institutional DeFi**: Security tokens trading on a DEX with full compliance enforcement -2. **Hybrid pools**: A regulated security token paired with a permissionless stablecoin -3. **Compliance-as-a-service**: Third-party compliance providers deploy their own hooks -4. **Regulatory clarity**: Regulators can verify compliance enforcement by inspecting the hook address - -### What This Prevents - -1. **Compliance bypass**: An investor cannot buy a security token on a permissionless pool because the token's `_update()` hook (in `SecurityToken`) also enforces compliance. Even if somehow a pool existed without a ComplianceHook, the underlying token transfer would revert. -2. **Unauthorized market making**: Only whitelisted addresses can add liquidity to regulated pools. - -## Trade Surveillance - -`ComplianceHook.afterSwap` emits events consumed by the off-chain surveillance system: - -```solidity -event RegulatedSwap( - address indexed trader, - address indexed token0, - address indexed token1, - int256 amount0, - int256 amount1, - uint160 sqrtPriceX96, - uint128 liquidity, - int24 tick, - uint256 timestamp -); -``` - -The surveillance system (`lux/cex` monitoring module) indexes these events for: -- Wash trading detection -- Insider trading pattern analysis -- Market manipulation alerts -- FINRA trade reporting (TRACE for fixed income, ORF for OTC equity) - -## Gas Considerations - -The ComplianceHook adds a `ComplianceRegistry.canTransfer()` call to every swap. This is a `view` call that reads: -- 2 storage slots (whitelist sender, whitelist receiver) -- 2 storage slots (blacklist sender, blacklist receiver) -- 1 storage slot (lockup sender) -- N module calls (typically 0-3 modules, each 1-3 storage reads) - -Estimated additional gas per swap: ~8,000-15,000 gas depending on module count. This is acceptable for regulated markets where compliance cost is already priced in. - -On the native DEX precompile (LP-9010), compliance checks execute as precompile-to-precompile calls, reducing overhead to ~3,000-5,000 gas. - -## Deployment - -1. Deploy `ComplianceRegistry` (if not already deployed for this token) -2. Mine a `CREATE2` salt producing an address with `0x07D4` prefix -3. Deploy `ComplianceHook` with the registry address using the mined salt -4. Create the regulated pool with the hook address -5. Add initial liquidity (liquidity provider must be whitelisted) - -## Security Considerations - -1. **Hook immutability**: Once a pool is initialized with a hook, the hook cannot be changed. This prevents compliance removal after pool creation. -2. **Registry upgrades**: The hook points to an immutable registry address. To upgrade compliance rules, deploy new modules and add them to the existing registry. Do not redeploy the registry. -3. **Router trust**: The `hookData` parameter is used to pass the actual trader address when a swap goes through a router.

Security tokens can be bridged between the C-Chain, Liquidity L2, Zoo EVM, and any Lux subnet. The bridge enforces compliance on both source and destination chains. Cross-listing with tZero uses the same bridge architecture for off-chain ATS settlement. - -## Motivation - -Security tokens issued on one Lux chain need to trade on others: -- Issued on C-Chain, traded on Liquidity L2 (lower fees, dedicated ATS infrastructure) -- Issued on C-Chain, traded on Zoo EVM (marketplace integration) -- Cross-listed on tZero (off-chain ATS, SEC-registered) - -Without a bridge, each chain would need its own token with its own compliance registry, and balances would diverge. The bridge maintains a single logical token supply across all chains. - -## Bridge Pattern - -### Lock/Mint (Source -> Destination) - -Used when moving tokens from the chain where the token was originally deployed (the "home chain") to a remote chain. - -``` -Home Chain (C-Chain) Remote Chain (Liquidity L2) --------------------- ------------------------- -1. User calls lock() - -> tokens transferred - to SecurityBridge contract - -> BridgeLock event emitted - 2. Relayer verifies the lock - via Warp message - 3.

Tokens are either locked on the home chain or minted on a remote chain. Never both. - -## Contract - -The `SecurityBridge` contract (deployed per-token, per-chain): - -```solidity -contract SecurityBridge is AccessControl { - bytes32 public constant BRIDGE_ROLE = keccak256("BRIDGE_ROLE"); - - SecurityToken public immutable TOKEN; - mapping(bytes32 => bool) public processedNonces; - - // Source chain operations (user-callable) - function lock(uint256 amount, uint256 destinationChainId, address destinationAddress) external; - function burn(uint256 amount, uint256 destinationChainId) external; - - // Destination chain operations (bridge operator only) - function bridgeMint(address recipient, uint256 amount, uint256 sourceChainId, bytes32 nonce) external; - function bridgeRelease(address recipient, uint256 amount, uint256 sourceChainId, bytes32 nonce) external; -} -``` - -### Nonce Deduplication - -Every bridge operation generates a nonce: - -```solidity -bytes32 nonce = keccak256(abi.encodePacked(sender, amount, destinationChainId, block.timestamp, block.number)); -``` - -The destination chain tracks `processedNonces[nonce]`. A nonce can only be processed once. This prevents replay attacks. - -### Role: BRIDGE_ROLE - -The `BRIDGE_ROLE` authorizes `bridgeMint()` and `bridgeRelease()`. This role must be held by: -- A T-Chain MPC multisig (LP-5013) for production deployments -- A Warp-verified relayer contract for automated bridging - -A single EOA must never hold `BRIDGE_ROLE` in production. - -## Warp Messaging - -### Protocol - -Lux Warp Messaging (LP-6022) provides native cross-subnet communication.

Submits the mint/release request to the MPC signing cluster -5. Broadcasts the signed transaction to the destination chain - -## Emergency Procedures - -### Pause - -Both the SecurityToken and SecurityBridge can be paused independently: -- `SecurityToken.pause()` halts all transfers including bridge operations -- Bridge-specific pause is achieved by revoking `BRIDGE_ROLE` from the operator - -### Stuck Funds - -If tokens are locked on the home chain but the destination chain fails to mint: -1. The lock event and nonce are recorded on-chain -2. After a timeout (configurable, default 24 hours), admin can call a recovery function to release locked tokens back to the sender -3. Recovery requires `DEFAULT_ADMIN_ROLE` (multisig) - -### Chain Halt - -If a destination chain halts: -1. Lock operations on the home chain continue to work (tokens accumulate in the bridge) -2. No mints occur on the halted chain -3. When the chain resumes, the relayer processes the backlog in order -4. Nonce deduplication prevents double-minting - -## Gas Costs - -| Operation | Chain | Estimated Gas | -|---|---|---| -| `lock()` | Home chain | ~65,000 (transfer + event) | -| `burn()` | Remote chain | ~45,000 (burn + event) | -| `bridgeMint()` | Remote chain | ~55,000 (mint + nonce check + event) | -| `bridgeRelease()` | Home chain | ~50,000 (transfer + nonce check + event) | - -Compliance checks in `lock()` add ~8,000-15,000 gas (via SecurityToken._update). - -## Security Considerations - -1. **Nonce replay**: Each nonce can only be processed once. The nonce includes `block.timestamp` and `block.number`, making it unique per-block. Two locks in the same block from the same sender for the same amount produce different nonces due to different call positions. - -2. **Warp signature verification**: The destination chain verifies the BLS aggregate signature against the source subnet's registered validator set on the P-Chain. A compromised minority of validators cannot produce a valid Warp message (67% threshold minimum). - -3. **MPC key compromise**: If the MPC signing threshold is compromised, the attacker can mint tokens on destination chains. Mitigation: per-asset key groups, HSM backing, quarterly rotation, real-time monitoring of bridge events. - -4. **Compliance desynchronization**: If chain A whitelists a user and chain B has not synced yet, the user can lock on A but cannot trade on B. This is a liveness issue, not a safety issue -- compliance sync latency is the bottleneck. The compliance service targets < 30 second sync across chains. - -5. **Double-spend via reorg**: If the source chain reorgs after a lock is processed, the destination chain has already minted. Mitigation: wait for finality before processing (Lux finality is 1ms, so reorgs are practically impossible under normal conditions). - -6. **Token supply audit**: The bridge invariant (locked + remote supply = home supply) must be auditable. Both the home chain bridge balance and remote chain total supply are public on-chain state. An automated monitor verifies the invariant every block. - -## Reference - -| Resource | Location | -|---|---| -| SecurityBridge contract | `github.com/luxfi/standard/contracts/securities/bridge/SecurityBridge.sol` | -| Warp Messaging 2.0 | `lp-6022-warp-messaging-20-native-interchain-transfers.md` | -| T-Chain MPC Custody | `lp-5013-t-chain-decentralised-mpc-custody-and-swap-signature-layer.md` | -| Teleport Bridge Architecture | `lp-6332-teleport-bridge-architecture-unified-cross-chain-protocol.md` | -| LPS-001 Digital Securities | `LPS-001-digital-securities.md` | -| tZero API | https://tzero.com | - -## Copyright - -Copyright (c) 2026 Lux Partners Limited.

The release explicitly carves out protocol mining, all four models of staking (solo, delegated, liquid, and restaking), and no-consideration airdrops as **administrative activities outside the Howey test**. This document analyzes the implications for every layer of the Lux Network stack — smart contract standards, EVM precompiles, node consensus, MPC custody, and bridge infrastructure — and identifies gaps that must be addressed to maintain full regulatory compliance as an open, permissionless, trustless, liquid protocol. + +Two pending federal bills further shape the landscape: the **CLARITY Act** seeks to make the commodity classification permanent and define clear jurisdictional boundaries between the SEC and CFTC; the **GENIUS Act** establishes a federal framework for payment stablecoins. Both are analyzed with respect to Lux's existing implementation and required adaptations. + +## Motivation + +Lux Network operates as a permissionless, trustless Layer 1 blockchain with 14 purpose-built chains. The regulatory classification of its native asset (LUX), subnet tokens, staking rewards, airdrop distributions, and DeFi protocol operations determines whether Lux participants — validators, stakers, liquidity providers, bridge operators, and MPC signers — face securities registration requirements. + +The March 17 joint release is the most significant US regulatory clarification for blockchain protocols since the SEC's 2019 Framework for "Investment Contract" Analysis. It creates a clear path for protocols like Lux to operate lawfully in the United States without securities registration, provided the protocol's architecture and operations remain within the defined boundaries. + +This LP serves three purposes: + +1. **Legal positioning**: Document why Lux qualifies for commodity classification under the joint release +2. **Gap analysis**: Identify any technical or operational gaps across the stack +3. **Forward compliance**: Position Lux for the CLARITY Act and GENIUS Act before they become law + +## Regulatory Framework + +### 1. SEC/CFTC Joint Interpretive Release (March 17, 2026) + +#### Digital Commodity Classification + +The joint release names 16 crypto assets as digital commodities. The classification criteria, distilled from the release, are: + +| Criterion | Description | Lux Status | +|-----------|-------------|------------| +| **Sufficiently decentralized** | No single entity controls >20% of validation power, governance, or token supply | **PASS** — 5+ independent validator sets, no entity controls >20% | +| **Open-source protocol** | Core protocol code publicly available under permissive license | **PASS** — BSD-3-Clause (core), Ecosystem License (specialized chains) | +| **Permissionless participation** | Anyone can run a node, validate, or transact without approval | **PASS** — permissionless staking, no KYC required for base layer | +| **No promoter dependency** | Network operates independently of any founding team or company | **PASS** — protocol operates autonomously via consensus | +| **Functional utility** | Token has consumptive use (gas, staking, governance) beyond speculation | **PASS** — LUX pays gas, secures network via staking, governs subnets | + +#### Administrative Activities Exemption + +The release defines four categories of blockchain activity that do **not** constitute investment contracts under the Howey test: + +**1. Protocol Mining** +> Mining activity where participants contribute computational resources to validate transactions and secure a network in exchange for programmatically determined rewards is an administrative activity, not an investment of money in a common enterprise with expectation of profits derived from the efforts of others. + +**Lux mapping**: Lux uses proof-of-stake consensus (Snowman/Quasar), not proof-of-work mining. However, the release uses "mining" broadly to encompass all forms of programmatic validation reward. Lux validators contribute stake (not compute) and receive programmatically determined rewards from protocol inflation. The economic structure is identical: administrative participation → deterministic reward. + +**2. All Four Models of Staking** + +The release explicitly classifies four staking models: + +| Model | Definition | Lux Implementation | Status | +|-------|-----------|---------------------|--------| +| **Solo staking** | Operator runs own node, stakes own capital | P-Chain `addPermissionlessValidator` | **Implemented** (LP-1000) | +| **Delegated staking** | Holder delegates to a node operator without transferring custody | P-Chain `addPermissionlessDelegator` | **Implemented** (LP-1000) | +| **Liquid staking** | Holder stakes via a protocol that issues a liquid receipt token (LST) | sLUX liquid staking token | **Implemented** (LRC-20) | +| **Restaking** | LST or staked position is re-committed to secure additional services | Subnet validation with existing stake | **Implemented** (LP-1000) | + +The release states: +> Staking, in all four models described herein, is an administrative activity. The staker's return is a function of protocol parameters (inflation schedule, commission rate, uptime requirements) rather than the managerial efforts of a third party. Delegated staking does not transform the activity into a securities offering because the delegator retains economic ownership and can withdraw at any time; the node operator performs a ministerial function. + +**3. No-Consideration Airdrops** + +> Distribution of tokens without monetary consideration — including airdrops to existing holders, ecosystem participants, or community members — is not an investment of money and therefore cannot satisfy the first prong of the Howey test. + +**Lux mapping**: Genesis allocations, validator reward distributions, and community airdrops are all no-consideration distributions under this framework. The key requirement: recipients must not pay for the tokens. Lux's genesis distribution (vesting schedule with 7 unlock periods) satisfies this because the initial allocation is programmatic, not purchased. + +**4. Protocol Governance** + +> Participation in on-chain governance — voting on protocol parameters, treasury allocations, or upgrade proposals — using tokens that were obtained through staking, mining, or no-consideration distribution is an administrative activity. + +**Lux mapping**: Subnet governance, parameter voting via the P-Chain, and LP governance processes all qualify. + +#### What Remains Securities + +The release does **not** exempt: +- Token sales for investment purposes (ICOs, SAFTs, presales) +- Yield-bearing protocols where returns depend on a management team's efforts +- Tokens marketed primarily as investments with profit expectations +- Centralized lending/borrowing platforms + +**Lux implication**: The LP-3100 Digital Securities Standard and LP-3101 Compliance Hook remain essential for regulated security tokens issued on Lux. The commodity classification applies to LUX itself and to DeFi protocol participation — not to security tokens built on top of the platform. + +### 2. CLARITY Act (Pending) + +The **Crypto Legislation and Regulatory Innovation for Tokens in Your Economy (CLARITY) Act** is pending legislation that would: + +| Provision | Description | Lux Impact | +|-----------|-------------|------------| +| **Permanent commodity classification** | Codify the joint release's classification criteria into statute | Removes risk of future SEC reinterpretation | +| **SEC/CFTC jurisdiction split** | SEC regulates securities tokens; CFTC regulates commodity tokens and spot markets | Confirms CFTC as primary regulator for LUX | +| **Decentralization test** | Statutory definition of "sufficiently decentralized" with quantitative thresholds | Must ensure Lux meets any specific thresholds (e.g., Nakamoto coefficient) | +| **Safe harbor for developers** | 3-year safe harbor for token projects achieving decentralization | Protects Lux Foundation during transition periods | +| **Registration pathway** | Clear registration pathway for centralized token projects | Not directly applicable (Lux is decentralized) | + +**Gap analysis**: The CLARITY Act may impose specific quantitative decentralization metrics (e.g., minimum number of independent validators, maximum single-entity stake percentage). Current Lux architecture supports this but may need monitoring tooling. + +**Action items**: +- Implement on-chain decentralization metrics dashboard (Nakamoto coefficient, stake distribution Gini, geographic distribution) +- Ensure no single entity's stake exceeds any threshold specified in final bill text +- Document validator independence (separate legal entities, jurisdictions, infrastructure providers) + +### 3. GENIUS Act (S. 394) + +The **Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act** establishes: + +| Provision | Description | Lux Impact | +|-----------|-------------|------------| +| **Federal stablecoin framework** | Two-tier system: federally chartered or state-regulated issuers | Stablecoin issuers on Lux must comply | +| **Reserve requirements** | 1:1 backing with US dollars, Treasuries, or approved high-quality liquid assets | LRC-32 Compliant Stablecoin Standard must enforce | +| **Monthly attestation** | Registered CPA must attest to reserves monthly | On-chain attestation via A-Chain integration | +| **Redemption rights** | Holders must be able to redeem 1:1 within 1 business day | Smart contract must support instant or timed redemption | +| **Interoperability** | Stablecoins must be interoperable across platforms | Lux bridge (LP-3102) + Warp messaging | +| **Prohibition on algorithmic stablecoins** | No unbacked algorithmic stablecoins without meeting reserve requirements | Lux stablecoin standard must distinguish collateralized from algorithmic | +| **$10B threshold** | Issuers with >$10B in outstanding stablecoins must be federally regulated | Infrastructure-level: no action required | + +**Detailed analysis in LP-3104.** + +## Component Gap Analysis + +### Layer 1: Smart Contract Standards (`/standard/`) + +#### SecurityToken (LP-3100) — COMPLIANT + +| Requirement | Implementation | Gap | +|-------------|---------------|-----| +| ERC-1404 transfer restrictions | `detectTransferRestriction()` | None | +| Compliance module chain | `ComplianceRegistry` + `IComplianceModule` | None | +| Accreditation verification | `accreditationStatus` field (0/1/2) | None | +| Jurisdiction blocking | `JurisdictionModule` | None | +| Rule 144 lockup | `LockupModule` | None | +| Document registry | `DocumentRegistry` with IPFS hashing | None | +| Dividend distribution | `DividendDistributor` | None | +| Corporate actions | `CorporateActions` (splits, mergers) | None | + +**Assessment**: The securities standard is fully implemented for regulated security tokens.

No transfer restrictions are required for commodity-classified tokens. The standard correctly does not impose compliance overhead on non-security tokens. + +**Assessment**: No gap.

The sLUX contract must NOT include any discretionary yield management or active strategy selection — that would re-invoke Howey. + +#### Airdrop Contracts — COMPLIANT + +No-consideration airdrops are outside Howey's first prong. Lux genesis allocations and reward distributions qualify because: +- Validators receive rewards for administrative work (uptime, consensus participation) +- Genesis allocations vest programmatically (no managerial intermediary) +- Community airdrops require no monetary payment + +**Requirement**: Airdrop contracts must not require payment or impose investment-like lock-up terms that could imply an investment expectation. + +### Layer 2: EVM Precompiles (`/precompile/`) + +#### Post-Quantum Cryptography — COMPLIANT + +| Precompile | Address | Regulatory Relevance | Gap | +|------------|---------|---------------------|-----| +| ML-DSA | `0x0200...0007` | FIPS 204 compliance — meets NIST standards for digital signatures | None | +| Ringtail | `0x0200...000B` | Threshold signatures for institutional custody | None | +| PQCrypto | `0x0200...0009` | Multi-PQ operations | None | + +**Assessment**: Post-quantum cryptography strengthens regulatory positioning by demonstrating forward-looking security posture.

Permissionless Base Layer + +The commodity classification depends on Lux being permissionless. Any protocol change that introduces mandatory identity verification, transaction censorship, or validator approval at the base layer would **jeopardize the commodity classification**. + +**Rule**: Compliance is always OPT-IN, never OPT-IN-OR-YOU-CANT-USE-THE-NETWORK. + +### 2. Programmatic Rewards + +Staking rewards, validator compensation, and protocol distributions must remain **programmatically determined** by protocol parameters. Any mechanism that introduces discretionary yield management (e.g., a team deciding reward rates, manual allocation of treasury funds as yield) would invoke the Howey test. + +**Rule**: All reward calculations must be deterministic functions of on-chain state. + +### 3. Non-Custodial Architecture + +MPC, bridge, and staking implementations must ensure no single party has custody of user assets. The threshold signature model (FROST, CGGMP21) is architecturally non-custodial. This must be preserved. + +**Rule**: No MPC implementation shall allow fewer than t signers (where t > 1) to move user assets. + +### 4. Securities/Commodity Separation + +The protocol stack correctly separates: +- **Commodity layer**: Base chain (LUX, gas, staking) — permissionless, no compliance +- **Securities layer**: Opt-in compliance contracts (LP-3100, LP-3101, LP-3102) — regulated, KYC-gated +- **Stablecoin layer**: GENIUS Act compliance for US-regulated issuers (LP-3104) — regulated, attestation-gated + +This separation must be maintained. Mixing compliance requirements across layers would create regulatory confusion. + +### 5. Open Source and Transparent + +The commodity classification criteria include open-source availability. Core protocol code must remain publicly available. Specialized chain code under the Ecosystem License is permissible as long as the base protocol (P-Chain, X-Chain, C-Chain) remains BSD-3-Clause. + +## CLARITY Act Preparedness + +The CLARITY Act is described in its text as the legislative counterpart to the March 17 joint release.

A future administration could reinterpret the classification. The CLARITY Act would mitigate this risk by codifying the classification into law. + +**Mitigation**: Maintain architecture that satisfies the most conservative interpretation of decentralization. Do not take actions that could be construed as centralized control. + +### Compliance Boundary Integrity + +The separation between the permissionless commodity layer and the regulated securities layer is load-bearing. If compliance logic leaks into the base layer (e.g., mandatory KYC for gas transactions), the entire commodity classification could be challenged. + +**Mitigation**: Compliance modules must remain opt-in. Subnet-level compliance is acceptable. Base-layer compliance gates are prohibited. + +### MPC Custody Risk + +If an MPC implementation is found to be custodial (e.g., a single operator can reconstruct the full key), bridge operators and staking services could face securities custody registration requirements. + +**Mitigation**: Formal architectural review of all MPC implementations. Publish non-custody attestation. + +### GENIUS Act Non-Compliance + +If Lux-based stablecoins do not meet GENIUS Act requirements when it passes, issuers face enforcement. This is an issuer-level risk, not a protocol-level risk, but platform reputation is affected. + +**Mitigation**: Implement LP-3104 before the GENIUS Act is enacted. + +## Economic Impact + +The commodity classification has significant positive economic impact: + +1. **Reduced compliance cost**: Base-layer operations require no securities compliance +2. **Broader participation**: Permissionless staking attracts more validators +3. **DeFi growth**: DEX trading of commodity tokens requires no ATS registration +4. **Institutional adoption**: Clear regulatory status reduces legal risk for institutional participants +5. **Stablecoin ecosystem**: GENIUS Act compliance enables regulated stablecoin issuance on Lux + +## Open Questions + +1. **CLARITY Act thresholds**: What specific quantitative decentralization metrics will be required?

This LP specifies the on-chain contract extensions, attestation integrations, and operational requirements that stablecoin issuers on Lux Network must implement to comply with the GENIUS Act. It extends the existing LRC-32 Compliant Stablecoin Standard with reserve proof mechanisms, timed redemption guarantees, issuer registry contracts, and A-Chain attestation records for monthly CPA attestations. + +## Motivation + +The GENIUS Act will be the first comprehensive US federal framework for stablecoin regulation. Unlike the March 17 SEC/CFTC joint release which classifies native tokens as commodities, the GENIUS Act specifically targets **payment stablecoins** — tokens designed to maintain a stable value pegged to a reference asset. + +Stablecoins on Lux (both native and bridged) must comply before the Act is enacted to avoid enforcement risk. The protocol should provide standards-compliant contracts so issuers can deploy GENIUS-compliant stablecoins without building custom infrastructure. + +Key GENIUS Act requirements that affect on-chain architecture: + +1. **Reserve transparency**: 1:1 backing must be verifiable +2. **Redemption rights**: Holders must be able to redeem at par within 1 business day +3. **Attestation**: Monthly reserve attestation by a registered CPA +4. **Issuer licensing**: Two-tier system (federal or state-regulated) +5. **Algorithmic stablecoin treatment**: Unbacked algorithmic stablecoins face additional scrutiny +6. **Consumer protection**: Stablecoin holder claims have priority in issuer insolvency + +## Specification + +### 1. Stablecoin Type Classification + +Every stablecoin deployed on Lux must declare its type at deployment: + +```solidity +// SPDX-License-Identifier: MIT +pragma solidity ^0.8.24; + +enum StablecoinType { + FIAT_COLLATERALIZED, // USD/Treasury-backed (GENIUS compliant path) + CRYPTO_COLLATERALIZED, // Over-collateralized by crypto assets + ALGORITHMIC, // Algorithmic supply adjustment (restricted under GENIUS) + HYBRID // Combination (must meet GENIUS reserves for fiat peg) +} +``` + +GENIUS Act compliance is **mandatory** for `FIAT_COLLATERALIZED` and `HYBRID` types when the issuer is US-regulated. `CRYPTO_COLLATERALIZED` and `ALGORITHMIC` types are subject to additional disclosure requirements but may not qualify as "payment stablecoins" under the Act. + +### 2.

Issuer is registered and active +2. Last attestation is within 35 days (monthly + 5-day grace period) +3. License type matches jurisdiction requirements + +### 3. Reserve Attestation + +#### On-Chain Attestation Record + +Each monthly CPA attestation is recorded on the A-Chain (Attestation Blockchain) and referenced on the C-Chain: + +```solidity +interface IReserveAttestation { + struct Attestation { + bytes32 attestationId; // A-Chain attestation ID + address issuer; // Stablecoin issuer + address stablecoin; // Stablecoin contract address + uint256 totalSupply; // Total stablecoin supply at attestation time + uint256 totalReserves; // Total reserves in USD (18 decimals) + uint256 reserveRatio; // Ratio (1e18 = 100%) + string cpaFirm; // Registered CPA firm name + bytes32 reportHash; // IPFS/Arweave hash of full CPA report + uint256 attestedAt; // Timestamp of attestation + uint256 reportPeriodStart; // Period covered start + uint256 reportPeriodEnd; // Period covered end + } + + event AttestationRecorded( + bytes32 indexed attestationId, + address indexed issuer, + uint256 reserveRatio, + uint256 attestedAt + ); + + function recordAttestation(Attestation calldata attestation) external; + function getLatestAttestation(address issuer) external view returns (Attestation memory); + function getAttestationHistory(address issuer, uint256 count) + external view returns (Attestation[] memory); + function isAttestationCurrent(address issuer) external view returns (bool); +} +``` + +#### Reserve Composition Breakdown + +The GENIUS Act specifies approved reserve assets. The attestation must break down reserve composition: + +```solidity +struct ReserveBreakdown { + uint256 usdCash; // US dollar deposits at insured depository institutions + uint256 usTreasuries; // US Treasury bills (maturity <= 93 days) + uint256 treasuryRepos; // Fully collateralized Treasury repurchase agreements + uint256 centralBankDeposits; // Federal Reserve deposits + uint256 otherApproved; // Other assets approved by the primary federal regulator +} +``` + +All fields denominated in USD with 18 decimal precision. + +### 4.

Off-chain settlement for fiat redemption is the issuer's responsibility. The on-chain contract burns tokens upon `requestRedemption()` and records the obligation. + +### 5. Enhanced LRC-32 Interface + +The complete GENIUS-compliant stablecoin interface: + +```solidity +interface ILRC32GENIUS is IERC20 { + // Type and issuer + function stablecoinType() external view returns (StablecoinType); + function issuer() external view returns (address); + function pegAsset() external view returns (string memory); // "USD", "EUR", etc. + + // Reserve transparency + function totalReserves() external view returns (uint256); + function reserveRatio() external view returns (uint256); // 1e18 = 100% + function lastAttestationTime() external view returns (uint256); + function isFullyBacked() external view returns (bool); + + // Redemption + function requestRedemption(uint256 amount) external returns (uint256 requestId); + function maxRedemptionTime() external view returns (uint256); + + // Compliance + function isGENIUSCompliant() external view returns (bool); + function issuerLicense() external view returns (IIssuerRegistry.LicenseType); + + // Mint/burn (issuer only) + function mint(address to, uint256 amount) external; + function burn(uint256 amount) external; +} +``` + +`isGENIUSCompliant()` returns `true` if and only if: +1. `stablecoinType` is `FIAT_COLLATERALIZED` or `HYBRID` +2. Issuer is registered in `IssuerRegistry` with valid license +3. Latest attestation is within 35 days +4. `reserveRatio` >= 1e18 (100% backing) +5. `maxRedemptionTime` <= 86400 (24 hours) + +### 6. Algorithmic Stablecoin Disclosure + +For `ALGORITHMIC` and `HYBRID` type stablecoins, additional disclosure is required: + +```solidity +interface IAlgorithmicDisclosure { + struct StabilityMechanism { + string mechanismType; // "rebase", "seigniorage", "fractional", etc. + string description; + uint256 collateralRatio; // For partial collateralization (1e18 = 100%) + address[] collateralTokens; // Tokens used as collateral + bool hasDeathSpiral; // Whether the mechanism can enter a death spiral + string riskDisclosure; // IPFS hash of risk disclosure document + } + + function stabilityMechanism() external view returns (StabilityMechanism memory); +} +``` + +### 7. Insolvency Priority + +The GENIUS Act grants stablecoin holders priority claims in issuer insolvency. This cannot be enforced purely on-chain but the contract records holder balances that serve as evidence of claims: + +```solidity +/// @notice Snapshot holder balances for insolvency proceedings +/// @dev Called by issuer or regulator; creates immutable record +function snapshotBalances() external returns (uint256 snapshotId); + +/// @notice Get holder balance at snapshot time +function balanceAtSnapshot(uint256 snapshotId, address holder) + external view returns (uint256); +``` + +### 8. Oracle Integration for Reserve Verification + +Real-time reserve verification uses the Oracle precompile (LP-9011): + +```solidity +interface IReserveOracle { + /// @notice Get latest reserve data from oracle + /// @return totalReserves Total reserve value in USD (18 decimals) + /// @return timestamp When the data was last updated + /// @return source Data source identifier + function getReserveData(address stablecoin) + external view returns (uint256 totalReserves, uint256 timestamp, string memory source); +} +``` + +Oracle feeds can source from: +- Bank API attestations (via trusted oracle nodes) +- Treasury holdings verification services +- Auditor data feeds + +### 9. Cross-Chain Stablecoin Bridging + +When bridging GENIUS-compliant stablecoins via LP-3102: + +1. Source chain: Burns stablecoin, records redemption obligation +2. Destination chain: Mints stablecoin, inherits issuer compliance status +3. Both chains: Check `isGENIUSCompliant()` before mint/burn +4. Bridge relayer: Passes attestation status cross-chain via Warp message + +## Rationale + +### Why Extend LRC-32 Rather Than Create New Standard + +LRC-32 already defines compliant stablecoin behavior. The GENIUS Act requirements are an extension, not a replacement. Existing LRC-32 stablecoins can upgrade to GENIUS compliance by implementing the additional interfaces. + +### Why On-Chain Attestation Records + +The GENIUS Act requires monthly CPA attestation. Recording these on the A-Chain provides: +1. Immutable proof of attestation timing (no backdating) +2. Cross-chain verifiability (any Lux chain can check compliance) +3. Public transparency (anyone can verify reserve status) +4. Automated compliance checking (`isAttestationCurrent()`) + +### Why 35-Day Grace Period + +Monthly attestation with a 35-day validity window provides 5 days of buffer for CPA report preparation and on-chain submission. This prevents stablecoins from becoming non-compliant due to minor delays. + +### Why Type Classification at Deployment + +The GENIUS Act treats different stablecoin models differently. Classifying at deployment: +1. Prevents type-switching (algorithmic stablecoin pretending to be fiat-backed) +2. Enables automated compliance routing +3. Provides clear disclosure to holders + +## Backwards Compatibility + +Existing LRC-20 stablecoins on Lux that do not implement ILRC32GENIUS are unaffected. The GENIUS Act compliance is opt-in at the contract level. However, exchanges and DeFi protocols may choose to only list GENIUS-compliant stablecoins. + +Existing LRC-32 stablecoins can upgrade by deploying a wrapper or proxy contract implementing the additional interfaces. + +## Test Cases + +### Reserve Attestation + +``` +Given: Issuer registered with FEDERAL_OCC license +When: recordAttestation(attestation) called with reserveRatio = 1.05e18 +Then: isAttestationCurrent(issuer) returns true + isGENIUSCompliant() returns true + +Given: Last attestation was 36 days ago +When: isAttestationCurrent(issuer) called +Then: Returns false + isGENIUSCompliant() returns false +``` + +### Redemption + +``` +Given: Holder has 1000 stablecoins +When: requestRedemption(1000e18) called +Then: RedemptionRequested event emitted + Holder balance reduced by 1000e18 + Deadline set to block.timestamp + 86400 + +Given: Redemption request exists with deadline not passed +When: completeRedemption(requestId) called by issuer +Then: RedemptionCompleted event emitted + Status set to COMPLETED +``` + +### Type Enforcement + +``` +Given: Stablecoin deployed as ALGORITHMIC +When: isGENIUSCompliant() called +Then: Returns false (algorithmic stablecoins require additional regulatory approval) + +Given: Stablecoin deployed as FIAT_COLLATERALIZED + Issuer registered, attestation current, reserves >= 100% +When: isGENIUSCompliant() called +Then: Returns true +``` + +## Reference Implementation + +Reference implementations to be provided in: +- `/standard/contracts/stablecoin/LRC32GENIUS.sol` — Full GENIUS-compliant stablecoin +- `/standard/contracts/stablecoin/IssuerRegistry.sol` — Issuer registration and tracking +- `/standard/contracts/stablecoin/ReserveAttestation.sol` — A-Chain attestation bridge + +## Security Considerations + +### Oracle Manipulation + +Reserve oracle feeds are a critical trust point. If an oracle falsely reports reserves, holders may be misled. Mitigations: +- Multi-source oracle aggregation (LP-9011) +- Outlier detection and circuit breakers +- On-chain vs. off-chain attestation cross-reference + +### Redemption Bank Run + +If all holders request redemption simultaneously, the 1-business-day guarantee depends on off-chain reserve liquidity.

The precompile provides four core functions: `sendWarpMessage` for emitting cross-chain messages, `getVerifiedWarpMessage` for retrieving validator-attested messages, `getVerifiedWarpBlockHash` for cross-chain block hash verification, and `getBlockchainID` for chain identification.

Poseidon2 is a ZK-friendly, post-quantum safe cryptographic hash designed for arithmetic circuits. This precompile enables native Merkle tree operations, receipt hashing, and commitment schemes on the Lux Z-Chain. - -**Key Properties:** -- **Post-Quantum Safe**: Hash-based security (no discrete log assumptions) -- **ZK-Efficient**: ~300 R1CS constraints vs ~25,000 for SHA-256 -- **Production Lane**: Immutable API, stable address `0x0501` - -## Motivation - -The rise of Zero-Knowledge (ZK) applications requires a hash function that is both efficient inside ZK circuits and cheap to execute on-chain. Standard hash functions like SHA-256 are inefficient in ZK circuits, while ZK-friendly hashes like Pedersen are not post-quantum safe. Poseidon2 offers the best of both worlds: it is highly efficient in ZK circuits, post-quantum safe, and fast in native execution. This LP proposes a precompile for Poseidon2 to make it a first-class primitive in the Lux EVM, enabling a new generation of ZK-powered applications. - -## Rationale - -### Why Poseidon2? - -| Property | Poseidon2 | Pedersen | SHA-256 | -|----------|-----------|----------|---------| -| ZK Constraints | ~300 | ~750 | ~25,000 | -| PQ-Safe | ✅ Hash-based | ❌ Discrete log | ✅ Hash-based | -| Gas Cost | ~800 | ~6,000 | ~60 (native) | -| Native EVM | ❌ → ✅ This LP | ❌ | ✅ | - -### Use Cases - -1. **Z-Chain Receipt Hashing**: Universal receipts use Poseidon2 for binding -2. **Merkle Trees**: Privacy pools, rollup state roots, commitment trees -3. **Note Commitments**: ZNotePQ uses `Poseidon2(amount, asset, owner, blinding)` -4. **Nullifier Generation**: `Poseidon2(commitment, secretKey)` - -### Design Decisions - -This LP adopts **fixed instantiations** over EIP-5988's generic approach: - -1. **Fixed Parameters**: Circomlib-compatible, 128-bit security -2. **Domain Separation**: Explicit DST constants for each use case -3. **Immutable API**: v1 never changes;

This LP explores community -> interest and documents the security considerations before any implementation. - -## Abstract - -LP-3668 proposes a native EVM precompile for Pedersen hash, a commitment scheme based on elliptic curve scalar multiplication. Pedersen hash is used extensively in ZK circuits for: - -- Merkle tree commitments (Zcash, Tornado Cash) -- Note commitments in privacy protocols -- Homomorphic operations on commitments - -**This LP is exploratory** and requires community input on curve selection, encoding rules, and security properties before implementation can proceed. - -## Open Questions (Critical - Blocks Implementation) - -### 1. There Is No Standard - -Unlike Poseidon (EIP-5988), there is **no Ethereum proposal for Pedersen hash**. This means: -- No consensus on curve choice -- No consensus on generator derivation -- No consensus on encoding format -- No reference implementation to follow - -**Implication**: Lux would be defining a de-facto standard. This requires extreme care. - -### 2. Pedersen Is a Family, Not a Single Function - -"Pedersen hash" refers to multiple distinct constructions: - -| Variant | Curve | Usage | Notes | -|---------|-------|-------|-------| -| Baby-Jubjub Pedersen | Baby-Jubjub (BN254 subgroup) | circom, Zcash | Most common in circom ecosystem | -| Jubjub Pedersen | Jubjub (BLS12-381 subgroup) | Zcash Sapling | Different curve | -| Windowed Pedersen | Various | Zcash | Optimized for specific bit widths | -| Pedersen Commitment | Generic | Bulletproofs | Different security model | - -**Question**: Which variant should Lux implement? Recommend Baby-Jubjub for circom compatibility. - -### 3. Subtle Security Pitfalls - -Pedersen hash is **easier to get wrong** than Poseidon: - -#### 3.1 Non-Unique Encodings -Using only x-coordinate can cause collisions with point negation: -``` -P = (x, y) and -P = (x, -y) both have same x-coordinate -``` -**Mitigation**: Use full point encoding or canonical y-coordinate selection. - -#### 3.2 Related Generators -If generators G_i are derived improperly, an attacker might find discrete log relations. -``` -If G_1 = k * G_0 for known k, the hash is completely broken. -``` -**Mitigation**: Deterministic hash-to-curve derivation (no one can claim trapdoor). - -#### 3.3 Variable-Length Input Issues -Without proper length encoding, different inputs can produce same hash: -``` -H("ab", "") vs H("a", "b") - might collide without length prefix -``` -**Mitigation**: Explicit length prefix inside the hash. - -#### 3.4 Point-at-Infinity Edge Cases -Edge case handling for zero scalars must be carefully specified. - -### 4. Curve Selection - -**Recommended**: Baby-Jubjub (embedded curve in BN254) - -| Property | Baby-Jubjub | Jubjub | -|----------|-------------|--------| -| Parent Curve | BN254 | BLS12-381 | -| Circom Compatible | ✅ Yes | ❌ No | -| Ethereum Compatible | ✅ Yes | Partial | -| Security Level | 128-bit | 128-bit | -| Order | ~251 bits | ~252 bits | - -Baby-Jubjub is embedded in BN254, meaning Pedersen operations can be efficiently verified inside BN254 Groth16 circuits. - -### 5. Generator Derivation - -Generators MUST be derived deterministically so no one can claim to know discrete logs: - -``` -G_0 = hash_to_curve("Lux.Pedersen.Generator.0") -G_1 = hash_to_curve("Lux.Pedersen.Generator.1") -... -``` - -**Required**: Publish derivation seed and algorithm; verifiable by anyone. - -### 6.

Baby-Jubjub curve provides BN254 compatibility for Groth16 - -## Backwards Compatibility - -This LP introduces new precompile addresses and does not affect existing functionality. - -## Security Considerations - -### 1. No Mainstream Standard Exists - -**Risk**: Without an EIP or widely-adopted standard, Lux would be defining its own. Errors in specification could be catastrophic. - -**Mitigation**: -- Extensive review before implementation -- Test vectors from multiple independent implementations -- Security audit specifically for curve operations - -### 2. Discrete Log Hardness - -Pedersen hash security relies on discrete log being hard on Baby-Jubjub. - -**Risk**: If ECDLP is broken (e.g., by quantum computers), all Pedersen hashes become reversible. - -**Mitigation**: -- Baby-Jubjub is 128-bit secure against classical attacks -- Consider post-quantum alternatives for long-term commitments - -### 3. Generator Trust - -**Risk**: If generators are not derived verifiably, someone might know discrete logs. - -**Mitigation**: Deterministic hash-to-curve from published seed. Anyone can verify generators. - -### 4. Point Validation - -All input points must be validated: -- On the curve -- In the correct subgroup (avoid small-subgroup attacks) -- Not point at infinity - -### 5.

The motivation stems from the well-recognized “quantum threat” to blockchain security: core algorithms like ECDSA (used for digital signatures) and ECDH are vulnerable to Shor’s algorithm, meaning a sufficiently powerful quantum computer could break private keys and forge signatures. While such quantum computers are not yet available, Lux adopts a proactive stance. This proposal evaluates and selects post-quantum (PQ) algorithms for crucial components such as transaction signatures and hashing. It highlights NIST’s recent standardization efforts, noting that the first suite of PQ algorithms (finalized in 2022) are based on structured lattices and hash-based cryptography. In particular, Lux plans to support a lattice-based signature scheme (e.g., CRYSTALS-Dilithium or a variant) for validator authentication and user wallets, as these schemes rely on mathematical problems (lattice Short Vector problems) believed to be resistant to quantum attacks. Additionally, hash-based signatures like XMSS or SPHINCS+ are considered for one-time or few-time signatures, given their minimal security assumptions (collision-resistant hashes) and existing standardization (XMSS is specified in RFC 8391). LP-4 details a transition plan whereby Lux accounts can upgrade from classical ECDSA/secp256k1 keys to dual-key addresses that include a PQ public key. This ensures backward compatibility (similar to how Ethereum is exploring introducing Lamport or Winternitz one-time signatures for account security). The proposal also addresses performance considerations: PQ signatures are generally larger or slower to verify than ECDSA, which could impact block size and verification time. To mitigate this, Lux may leverage hybrid approaches (e.g., using efficient lattice signatures and optimizing verification via batching or elliptic-curve accelerators... + +## Motivation + +[TODO] + +## Specification + +[TODO] + +## Rationale + +[TODO] + +## Backwards Compatibility + +[TODO] + +## Security Considerations + +[TODO] + +## Implementation + +### ML-DSA Post-Quantum Signatures (FIPS 204) + +**Location**: `~/work/lux/crypto/mldsa/` +**GitHub**: [`github.com/luxfi/node/tree/main/crypto/mldsa`](https://github.com/luxfi/node) + +**Key Files**: +- [`mldsa.go`](https://github.com/luxfi/node/blob/main/crypto/mldsa/mldsa.go) - ML-DSA-65 signature implementation (7.7 KB) +- [`mldsa_test.go`](https://github.com/luxfi/node/blob/main/crypto/mldsa/mldsa_test.go) - Comprehensive test suite with 11 test cases (6.2 KB) + +**Algorithm**: ML-DSA-65 (Dilithium, NIST Level 3) +- Public Key Size: 1,952 bytes +- Signature Size: 3,309 bytes +- Quantum Security: ~192 bits + +**Testing**: +```bash +cd ~/work/lux/crypto/mldsa +go test -v ./... +```solidity + +### EVM ML-DSA Precompile + +**Location**: `~/work/lux/evm/precompile/contracts/mldsa/` +**GitHub**: [`github.com/luxfi/evm/tree/main/precompile/contracts/mldsa`](https://github.com/luxfi/evm/tree/main/precompile/contracts/mldsa) + +**Key Files**: +- [`contract.go`](https://github.com/luxfi/evm/blob/main/precompile/contracts/mldsa/contract.go) - Precompile contract (4.3 KB) +- [`contract_test.go`](https://github.com/luxfi/evm/blob/main/precompile/contracts/mldsa/contract_test.go) - Precompile tests (7.4 KB) +- [`IMLDSA.sol`](https://github.com/luxfi/evm/blob/main/precompile/contracts/mldsa/IMLDSA.sol) - Solidity interface (7.1 KB) + +**Precompile Address**: `0x0200000000000000000000000000000000000006` +**Gas Cost**: 100,000 base + 10 per message byte + +**Testing**: +```bash +cd ~/work/lux/evm/precompile/contracts/mldsa +go test -v ./... +``` + +## Test Cases + +### Unit Tests + +1. **Cryptographic Primitives** + - Test key generation + - Verify signature creation + - Test signature verification + +2. **Post-Quantum Security** + - Verify NIST compliance + - Test parameter validation + - Validate security levels + +3. **Performance Benchmarks** + - Measure key generation time + - Benchmark signing operations + - Test verification throughput + +### Integration Tests + +1. **Hybrid Signature Schemes** + - Test classical-PQ combinations + - Verify fallback mechanisms + - Test key rotation + +2. **Network Integration** + - Test consensus with PQ signatures + - Verify cross-chain compatibility + - Test upgrade transitions + +## Copyright + +Copyright and related rights waived via [CC0](../LICENSE.md). \ No newline at end of file diff --git a/LPs/lp-4005-quantum-safe-wallets-and-multisig-standard.md b/LPs/lp-4005-quantum-safe-wallets-and-multisig-standard.md new file mode 100644 index 00000000..44b66eef --- /dev/null +++ b/LPs/lp-4005-quantum-safe-wallets-and-multisig-standard.md @@ -0,0 +1,130 @@ +--- +lp: 4005 +title: Lux Quantum-Safe Wallets and Multisig Standard +tags: [pqc, wallet, threshold-crypto] +description: Focuses on the design of Lux's quantum-safe wallet infrastructure, including a new multisignature (multisig) standard that remains secure against quantum adversaries. +author: Lux Network Team (@luxfi) +discussions-to: https://github.com/luxfi/lps/discussions +status: Final +requires: 4 +type: Standards Track +category: Core +created: 2025-01-28 +activation: + flag: lp5-quantum-safe-wallets + hfName: "" + activationHeight: "0" +order: 5 +--- + +> **See also**: [LP-4: Quantum-Resistant Cryptography Integration in Lux](/docs/lp-4-quantum-resistant-cryptography-integration-in-lux/) + +## Abstract + +## Activation + +| Parameter | Value | +|--------------------|-------------------------------------------------| +| Flag string | `lp5-quantum-safe-wallets` | +| Default in code | N/A | +| Deployment branch | N/A | +| Roll-out criteria | N/A | +| Back-off plan | N/A | + +LP-5 focuses on the design of Lux’s quantum-safe wallet infrastructure, including a new multisignature (multisig) standard that remains secure against quantum adversaries. As Lux transitions its core signatures to post-quantum algorithms (per LP-4), user-facing wallet technology must follow suit. This proposal introduces support for hash-based and lattice-based signature schemes in Lux wallets. It specifies that a user’s Lux address can be associated with a quantum-resistant public key, such as an XMSS or Dilithium public key, instead of or in addition to the traditional elliptic curve key. A major component is the Lux Safe, a quantum-safe multisig wallet service, which LP-5 formalizes at the protocol level. In a Lux Safe multisig account, multiple parties each hold a share of a post-quantum key or have independent PQ keys, and the account requires a threshold of signatures on any transaction. The use of threshold signing is carefully designed to be compatible with PQ algorithms. For instance, if using lattice-based signatures, the proposal outlines how to aggregate partial signatures or how to perform a secure distributed key generation such that no single device ever holds the full private key (applying MPC techniques akin to those used in threshold ECDSA, but now in a lattice context). Recognizing the novelty of threshold PQ signatures, LP-5 references ongoing research in this arena – for example, experiments combining Falcon (lattice signature) with threshold schemes, and stateful hash-based multisigs where each cosigner uses a distinct XMSS tree for each approval. The Lux Safe design takes inspiration from conventional multisigs (like Bitcoin’s M-of-N script and Ethereum’s smart contract wallets) but builds in quantum resilience. It also emphasizes usability and security: for instance, using a hierarchical derivation of many one-time hash-based keys under the hood so that the wallet can generate a new PQ one-time address for each transaction (mitigating reuse i... The proposal cites the IETF’s XMSS standard (RFC 8391) as evidence that hash-based signatures are mature enough for production use. It also references that Lux Safe is already implemented as a product in the ecosystem, highlighting it as “our quantum-safe multisig wallet”, to be integrated at protocol level. Through LP-5, Lux aims to provide users and institutions with high assurance that even if large-scale quantum computers emerge, funds secured in Lux multisig wallets (which might protect exchange reserves or DAO treasuries) will remain safe. This enhances Lux’s appeal for “quantum-resistant custody.” In summary, LP-5 extends Lux’s security to the user and application layer by defining standards for quantum-resistant key management and multisignature transactions, aligning with global efforts (by NIST and IETF) to make cryptocurrency systems ready for the quantum age. + +## Motivation + +[TODO] + +## Specification + +[TODO] + +## Rationale + +[TODO] + +## Backwards Compatibility + +[TODO] + +## Security Considerations + +[TODO] + +## Implementation + +### Lux Safe Multisig Wallet + +**Location**: `~/work/lux/safe/` +**GitHub**: [`github.com/luxfi/safe/tree/main`](https://github.com/luxfi/safe/tree/main) + +**Quantum-Safe Wallet Components**: +- [`app/`]() - Next.js wallet application (React, TypeScript) +- [`react/`]() - Reusable React components for Safe interface +- [`contracts/`]() - Smart contract module (Solidity) + +**Key Features**: +- M-of-N multisig with post-quantum key support +- Hierarchical deterministic (HD) wallet derivation +- One-time signature capability (XMSS/hash-based) +- Zero-knowledge proof integration for privacy + +**Testing & Documentation**: +```bash +cd ~/work/lux/safe/app +npm install && npm test +``` + +### Wallet CLI and Key Management + +**Location**: `~/work/lux/cli/cmd/` +**GitHub**: [`github.com/luxfi/cli/tree/main/cmd`](https://github.com/luxfi/cli/tree/main/cmd) + +**Quantum-Safe Features**: +- Post-quantum key generation (ML-DSA, SLH-DSA, ML-KEM support) +- Hybrid key management (classical + post-quantum) +- Secure key storage and recovery +- Transaction signing with quantum-resistant algorithms + +**Testing**: +```bash +cd ~/work/lux/cli +make test # Run full CLI test suite +``` + +## Test Cases + +### Unit Tests + +1. **Cryptographic Primitives** + - Test key generation + - Verify signature creation + - Test signature verification + +2. **Post-Quantum Security** + - Verify NIST compliance + - Test parameter validation + - Validate security levels + +3. **Performance Benchmarks** + - Measure key generation time + - Benchmark signing operations + - Test verification throughput + +### Integration Tests + +1. **Hybrid Signature Schemes** + - Test classical-PQ combinations + - Verify fallback mechanisms + - Test key rotation + +2. **Network Integration** + - Test consensus with PQ signatures + - Verify cross-chain compatibility + - Test upgrade transitions + +## Copyright + +Copyright and related rights waived via [CC0](../LICENSE.md). \ No newline at end of file diff --git a/LPs/lp-4045-z-chain-encrypted-execution-layer-interface.md b/LPs/lp-4045-z-chain-encrypted-execution-layer-interface.md deleted file mode 100644 index 92479062..00000000 --- a/LPs/lp-4045-z-chain-encrypted-execution-layer-interface.md +++ /dev/null @@ -1,272 +0,0 @@ ---- -lp: 4045 -title: Z-Chain Encrypted Execution Layer Interface -description: Interface specification for Z-Chain's encrypted execution layer, including EVM precompiles, JSON-RPC extensions, and TEE design. -author: Zach Kelling (@zeekay) and Lux Team (@luxfi) -discussions-to: https://github.com/luxfi/lps/discussions -status: Review -type: Standards Track -category: Interface -created: 2025-07-24 -requires: 8000 -tags: [privacy, zk, core] -order: 45 ---- - -> **See also**: [LP-8000](./lp-4000-z-chain-zkvm-specification.md) (ZKVM Architecture), [LP-302](/docs/lp-0302-lux-z-a-chain-privacy-ai-attestation-layer/), [LP-503](/docs/lp-0503-validity-proof-system/) - -> **Note**: This LP specifies the EVM precompile interface for FHE/TEE operations.

Q-Chain achieves both fast classical consensus and post-quantum finality via an integrated hybrid consensus framework. Beyond quantum security, Q-Chain manages validator coordination, staking operations, chain creation, and network governance. It supports linear and DAG-based transaction processing through multiple consensus engines, and provides **dual-certificate finality** combining BLS-based classical finalization and Ringtail-based quantum-resistant threshold signatures. The protocol achieves sub-second finality while maintaining security against both classical and quantum adversaries. + +## Motivation + +Blockchain networks face an impending quantum threat that could undermine current cryptographic foundations: + +1. **Quantum Computing Threat**: Shor's algorithm can break elliptic curve cryptography, threatening all current blockchain signatures +2. **Performance Requirements**: Post-quantum cryptography must not sacrifice the sub-second finality users expect +3. **Transition Complexity**: Networks need smooth migration paths from classical to quantum-safe cryptography +4. **Unified Framework**: Multiple consensus variants (linear chains, DAGs) need consistent quantum protection + +Q-Chain addresses these challenges by providing a modular, high-performance consensus stack with built-in quantum resistance. + +## Post-Quantum Chains (PQC) – General + +A Post-Quantum Chain (PQC) is any chain in the Lux ecosystem that: + +- Runs the Lux PQ consensus (post-quantum BFT), +- Has a validator set backed by stake in LUX or a chain whose security_token ultimately resolves to LUX, +- Can accept checkpoint transactions from downstream chains, +- Can emit checkpoints to an upstream PQC (often Q-Chain). + +### Properties + +- **High-security**: PQC consensus uses post-quantum signatures (e.g. lattice/hash-based), with crypto-agility to allow future upgrades. +- **Configurable throughput**: A PQC can be low-throughput (like Q-Chain) or medium-throughput (e.g. a regional PQC) depending on its role. +- **Recursive**: A PQC itself may be a "parent" to: + - classical LSCs / L2s that use its stateRoot as their finality anchor, + - or even to other PQCs (if you want multi-layer PQ trees). + +### Requirements + +In RFC language: + +A PQC MUST: + - Run LuxPQConsensus (parametrized PBFT-like protocol with PQ signatures). + - Accept Checkpoint(tx) messages from authorized child chains. + - Produce Checkpoint(tx) messages to its parent PQC or to Q-Chain. + +A PQC MAY: + - Run application logic (EVM/WASM/etc.). + - Maintain its own QSF-like fee market for its children, denominated in its own security_token, + as long as it ultimately settles to LUX when checkpointing to Q-Chain. + +## Q-Chain – Root PQC + +Q-Chain is the distinguished root Post-Quantum Chain of the Lux ecosystem. It is a high-security, low-throughput PQC that: + +- Is validated by LUX-staked validators registered on P-Chain, +- Stores checkpoints from all chains and from other PQCs, +- Implements the global Quantum Security Fee (QSF) fee market in LUX on a per-byte basis, +- Acts as the canonical root of finality from which all other PQCs and Liquidity-Secured Chains derive their long-term safety. + +### Checkpoint Inclusion Mechanism + +The checkpoint inclusion mechanism is cryptographically sound and builds on Lux's post-quantum consensus and signing infrastructure: + +#### 1. Merkle Mountain Ranges (MMR) for Efficient Proofs + +Each child chain (LSC, L2, or PQC) maintains a Merkle Mountain Range of its block headers: + +```go +type ChainMMR struct { + peaks []Hash // Current MMR peaks + height uint64 // Current height + chainID ChainID // Source chain identifier + lastCheckpoint uint64 // Last checkpointed height +} + +func (mmr *ChainMMR) AddBlock(header BlockHeader) { + // Add block to MMR, update peaks + mmr.peaks = mmr.updatePeaks(header.Hash()) + mmr.height++ +} + +func (mmr *ChainMMR) GenerateProof(targetHeight uint64) *MMRProof { + // Generate inclusion proof for specific height + return generateMMRProof(mmr.peaks, targetHeight) +} +``` + +#### 2. Post-Quantum Signed Checkpoints + +Checkpoints are signed using the existing Lux PQ consensus infrastructure: + +```go +type Checkpoint struct { + ChainID ChainID // Source chain ID + StartHeight uint64 // First block in this checkpoint + EndHeight uint64 // Last block in this checkpoint + StartRoot Hash // MMR root at StartHeight-1 + EndRoot Hash // MMR root at EndHeight + BlockCount uint64 // Number of blocks included + StateRoot Hash // Final state root + Proof *MMRProof // MMR inclusion proof + QSFFee uint64 // Quantum Security Fee paid + ValidatorSet ValidatorSetID // Validator set ID +} + +type SignedCheckpoint struct { + Checkpoint Checkpoint + BLSsig []byte // Classical BLS aggregate signature + RingtailSig []byte // Post-quantum threshold signature + SignerBitmap []byte // Bitmap of signing validators +} +``` + +#### 3. Dual-Signature Verification + +Q-Chain validates checkpoints using both classical and post-quantum signatures: + +```go +func (q *QuasarConsensus) VerifyCheckpoint(signed *SignedCheckpoint) bool { + // 1. Verify MMR proof structure + if !verifyMMRProof(signed.Checkpoint.Proof, signed.Checkpoint.StartRoot, + signed.Checkpoint.EndRoot, signed.Checkpoint.BlockCount) { + return false + } + + // 2. Verify classical BLS signature + if !q.blsAgg.Verify(signed.Checkpoint.Hash(), signed.BLSsig) { + return false + } + + // 3. Verify post-quantum Ringtail signature + if !q.ringtail.Verify(signed.Checkpoint.Hash(), signed.RingtailSig) { + return false + } + + // 4. Verify validator set matches current epoch + currentSet := q.getCurrentValidatorSet() + if !currentSet.Matches(signed.ValidatorSet) { + return false + } + + // 5. Verify QSF fee payment + if !q.verifyQSFPayment(signed.Checkpoint.QSFFee, signed.Checkpoint.BlockCount) { + return false + } + + return true +} +``` + +#### 4. Verkle Tree Integration for State Proofs + +For chains that need state verification (not just block inclusion): + +```go +type StateProof struct { + StateRoot Hash // Root of state trie + Key []byte // Key being proven + Value []byte // Value at key + Proof []byte // Verkle proof + BlockHeight uint64 // Block height for this state +} + +func (q *QuasarConsensus) VerifyStateProof(proof *StateProof, checkpoint *Checkpoint) bool { + // Verify state proof against checkpoint's state root + return q.verkleTree.Verify(proof.StateRoot, proof.Key, proof.Value, proof.Proof) +} +``` + +#### 5. Checkpoint Processing Flow + +```sql +1. Child chain produces blocks and updates its MMR +2. At checkpoint interval (e.g., every 100 blocks): + - Generate MMR proof from last checkpoint to current height + - Create Checkpoint struct with metadata + - Sign with dual BLS+Ringtail signatures +3. Submit SignedCheckpoint to Q-Chain (or parent PQC) +4. Q-Chain validates: + - Cryptographic proofs (MMR + signatures) + - Validator set authorization + - QSF fee payment +5. If valid, Q-Chain includes checkpoint in next block +6. Q-Chain updates its global state with new chain head +``` + +#### 6. Security Properties + +- **Post-Quantum Security**: All signatures use Lux's dual BLS+Ringtail scheme +- **Efficient Proofs**: MMR provides O(log n) proofs for arbitrary block ranges +- **State Verifiability**: Optional Verkle proofs for state transitions +- **Economic Security**: QSF fees paid in LUX provide Sybil resistance +- **Validator Accountability**: Signer bitmaps enable slashing for misbehavior +- **Crypto-Agility**: Signature schemes can be upgraded via governance + +#### 7. Performance Characteristics + +- **Proof Size**: ~1-2 KB per checkpoint (MMR + signatures) +- **Verification Time**: ~5-10ms on modern hardware +- **Checkpoint Frequency**: Configurable per chain (e.g., every 10-1000 blocks) +- **Throughput**: Q-Chain can process 1000+ checkpoints/second +- **Storage**: MMR peaks allow pruning of old block data + +This mechanism ensures that Q-Chain can securely and efficiently include proofs of other networks' blocks while maintaining the full post-quantum security guarantees of the Lux consensus protocol. + +## The Quasar Consensus Stack + +Quasar is Lux Network's completely rewritten consensus protocol family, designed from scratch with quantum security, verkle trees, witness support, and FPC (Fast Path Consensus) similar to Sui: + +### 1.

-## Rationale - -FHE precompiles were designed with these principles: -1. Pure Go implementation avoids patent encumbrance and CGO complexity -2. Precompile addresses in 0x80-0x83 range avoid conflicts with Ethereum -3. Network key management enables confidential smart contracts -4. TFHE was chosen for boolean operations efficiency over BGV/CKKS - -## Security Considerations - -### Key Management - -- Network public key available to all for encryption -- Secret key NEVER exists in a single location -- Threshold t-of-n required for any decryption -- Key rotation every epoch (configurable) - -### Access Control - -Decrypt operations require: -1. Sender owns the ciphertext (created it or received via transfer) -2. T-Chain ACL approval for the decrypt -3. Threshold validators participate - -### Timing Attacks - -- Constant-time implementations required -- No early-exit on comparison operations -- Uniform gas costs regardless of plaintext values - -## Implementation Status - -### Completed ✅ - -- [x] **luxfi/tfhe Pure Go Library** (`github.com/luxfi/tfhe`) - - Boolean gates with blind rotation - - Integer types FheUint4-256 (including FheUint160 for addresses) - - Arithmetic: Add, Sub, Neg, ScalarAdd - - Comparisons: Eq, Lt, Le, Gt, Ge, Min, Max - - Bitwise: And, Or, Xor, Not, Shl, Shr - - Public key encryption (users encrypt without secret key) - - Deterministic RNG for blockchain consensus - - Binary serialization for keys and ciphertexts - - **18x faster** bootstrap key generation vs OpenFHE CGO - -- [x] **luxfi/fhe OpenFHE Fork** (`github.com/luxfi/fhe`) - - Full TFHE/FHEW/CKKS/BGV/BFV support - - fhEVM radix integer operations - - CGO bindings for Go integration - -- [x] **LuxFHE SDK Stack** (`github.com/luxfhe/*`) - - @luxfhe/v1-sdk: Standard single-key TFHE - - @luxfhe/v2-sdk: Threshold TFHE with T-Chain integration - - @luxfhe/contracts: Solidity FHE library (FHE.sol, token/, finance/) - - core/threshold/: Rust threshold TFHE library - - core/kms/: Rust Key Management System - - core/fhevm/: Full-stack FHEVM framework - - 25+ example applications (voting, auctions, poker, tokens) - -- [x] **FHE.sol Solidity Library** - - Encrypted types: ebool, euint8-256, eaddress - - All arithmetic, comparison, and bitwise operations - - Async decryption via FHEDecrypt precompile - - ICofhe interface for threshold operations - -- [x] **FHE Precompiles** (`evm/precompile/contracts/fhe/`) - - FHE Core (0x80): All FHE operations - - ACL (0x81): Access control for encrypted values - - FHEDecrypt (0x82): Threshold decryption gateway - -- [x] **T-Chain Threshold Decryption** - - 69-of-100 validator threshold - - Epoch-based key ceremonies - - CKKS multiparty protocol - - Warp messaging integration - -### In Progress 🔄 - -- [ ] **Mul/Div/Rem Operations in luxfi/tfhe** (expensive, ~10-20s per 8-bit operation) -- [ ] **@luxfhe/wasm Package** - Browser-native FHE via WASM bindings -- [ ] **GPU Acceleration** (CUDA/Metal backends) -- [ ] **Production Mainnet Deployment** - -### Package Namespace Migration - -The FHE SDK packages are migrating from `@luxfi/*` to `@luxfhe/*`: - -| Old Package | New Package | Status | -|-------------|-------------|--------| -| `@luxfi/fhe-sdk` | `@luxfhe/sdk` | ✅ Migrated | -| `@luxfi/fhe-contracts` | `@luxfhe/contracts` | ✅ Migrated | -| `@luxfi/fhe-threshold` | `@luxfhe/sdk-threshold` | ✅ Migrated | -| N/A | `@luxfhe/wasm` | 🔄 Planned | - -### Implementation Roadmap - -| Phase | Timeline | Focus | -|-------|----------|-------| -| 1 | Q1 2025 | Core precompiles + Pure Go FHE | -| 2 | Q2 2025 | T-Chain threshold + CGO acceleration | -| 3 | Q3 2025 | Async coprocessor + batching | -| 4 | Q4 2025 | Production hardening + audit | - -### Performance Targets - -| Backend | Add (ms) | Mul (ms) | Compare (ms) | Bootstrap (ms) | -|---------|----------|----------|--------------|----------------| -| luxfi/tfhe (Pure Go) | 2000 | TBD | 3000 | 50 | -| luxfi/fhe (CGO) | 0.2 | 5 | 50 | 200 | -| luxfi/fhe + GPU | 0.05 | 1 | 10 | 50 | - -*Benchmarks on M1 Max, 128-bit security* - -## Backwards Compatibility - -FHE precompiles are additive and do not affect existing EVM behavior.

Dilithium as Primary PQC Scheme**: CRYSTALS-Dilithium (ML-DSA) was selected over alternatives due to: +- NIST standardization (FIPS 204) providing regulatory certainty +- Fastest verification among lattice-based signatures (0.5ms) +- Reasonable signature size (3,293 bytes) compared to hash-based schemes +- Strong security proofs based on Module-LWE hardness + +**2. Hybrid Migration Strategy**: The phased BLS+Ringtail hybrid approach was chosen over immediate replacement because: +- Allows gradual validator migration without hard fork +- Maintains backward compatibility during transition +- Provides defense-in-depth (both schemes must be broken) +- Enables testing and optimization before full commitment + +**3. Lattice-Based Threshold Signatures**: Traditional threshold schemes (Shamir, BLS) are quantum-vulnerable: +- Threshold Dilithium preserves t-of-n security model +- No trusted dealer requirement (distributed key generation) +- Same verification as standard Dilithium (interoperability) + +**4. Signature Aggregation**: To mitigate bandwidth overhead: +- Batch verification reduces CPU cost by ~80% for bulk operations +- Aggregate signatures combine multiple signatures into smaller proofs +- Compression techniques reduce signature size by ~45% + +### Alternatives Considered + +- **SPHINCS+**: Hash-based signatures with 256-bit quantum security, but signature sizes (17KB+) and signing time (180ms) make it impractical for consensus. Reserved for checkpoint finality only. +- **Falcon**: Faster than Dilithium but requires complex floating-point operations and has side-channel concerns. Not NIST-standardized as primary. +- **Rainbow**: Multivariate signatures rejected due to cryptanalysis concerns that led to NIST removal. +- **Direct Replacement**: Immediate ECDSA deprecation rejected as too disruptive to existing infrastructure and validators. + +## Backwards Compatibility + +This LP introduces significant but managed breaking changes: + +### Transition Period + +**Phase 1 - Hybrid Mode (2025-2027)**: +- Validators MAY use either ECDSA or Dilithium signatures +- Consensus accepts both signature types +- No breaking changes for existing infrastructure +- New validators encouraged to use Dilithium + +**Phase 2 - Dilithium Primary (2027-2030)**: +- Dilithium signatures REQUIRED for new validators +- ECDSA signatures OPTIONAL for legacy validators +- SDK updates for Dilithium support mandatory +- Wallet providers must implement Dilithium signing + +**Phase 3 - ECDSA Deprecated (2030+)**: +- Pure Dilithium consensus +- ECDSA-only validators cannot participate +- Legacy transactions remain valid but cannot be created + +### Migration Requirements + +**Validators**: +- Generate Dilithium key pair via `lux quantum keygen` +- Update configuration to enable hybrid mode +- Transition to Dilithium-only after testing + +**Applications**: +- Update SDK to version with Dilithium support +- Handle larger signature sizes in transaction parsing +- Implement dual-verification during hybrid period + +**Bridges**: +- Upgrade threshold signatures to lattice-based schemes +- Update light client proof verification +- Maintain ECDSA verification for historical proofs + +## Security Considerations + +### Quantum Threat Model + +**Adversary Capabilities**: +- Access to large-scale quantum computer (10,000+ logical qubits) +- Can run Shor's algorithm (breaks ECDSA in O(n³) time) +- Can run Grover's algorithm (2× speedup on hash collisions) + +**Lux Defenses**: +- Dilithium resists Shor's algorithm (lattice problem) +- SPHINCS+ resists all known quantum

+### Phase 1: Validator Support (Q1 2026) +- Add ML-DSA public keys to validator registration +- Hybrid BLS + ML-DSA signing in consensus +- Gradual weight shift from BLS to ML-DSA + +### Phase 2: Transaction Support (Q2 2026) +- Deploy ML-DSA precompile to C-Chain +- Enable ML-DSA transaction signing +- Wallet integration for quantum-safe addresses + +### Phase 3: Full Transition (Q3 2026) +- ML-DSA becomes primary signature scheme +- BLS maintained for backwards compatibility +- New validators require ML-DSA keys + +## Security Considerations + +### Quantum Resistance + +**Lattice Security**: Based on MLWE problem +- No known quantum algorithms break lattice problems efficiently +- NIST analyzed security for 6+ years before standardization +- Conservative parameter selection (128/192/256-bit security) + +**Long-term Security**: +- Public keys captured today remain secure post-quantum +- Deterministic signatures prevent timing attacks +- Constant-time implementation in CIRCL library + +### Side-Channel Resistance + +**Constant-Time Operations**: +- All arithmetic operations run in constant time +- No secret-dependent branches +- No secret-dependent memory access + +**Implementation Quality**: +- CIRCL library used by Cloudflare in production +- Formal verification of critical components +- Regular security audits + +### Key Management + +**Validator Keys**: +- Generate fresh ML-DSA keys for each validator +- Store private keys in HSM when available +- Use separate keys for consensus vs transaction signing + +**Backup & Recovery**: +- ML-DSA private keys are 4,000 bytes (65% larger than ECDSA) +- Use seed-based key derivation (BIP-39 compatible) +- Encrypt backups with quantum-safe encryption (AES-256) + +## Backwards Compatibility + +**Hybrid Period (2026-2027)**: +- All validators support BOTH BLS and ML-DSA +- Transactions can use either ECDSA or ML-DSA +- Consensus requires both signature types to be valid + +**Legacy Support**: +- ECDSA addresses continue to function +- Cross-chain messaging supports both signature types +- Gradual deprecation of ECDSA over 2-3 years + +## Rationale + +### Why ML-DSA over alternatives? + +**vs SLH-DSA (LP-312)**: +- ML-DSA is 10-100x faster (417μs vs 40ms sign time) +- Smaller signatures (3,293 bytes vs 17,088-49,856 bytes) +- Trade-off: Lattice security assumptions vs hash-based conservative security + +**vs Classical Multivariate**: +- ML-DSA has stronger security analysis +- NIST standardized (vs academic proposals) +- Better performance and key sizes + +**vs Falcon (NIST finalist)**: +- ML-DSA has simpler implementation (no floating point) +- More conservative security parameters +- Deterministic signing (Falcon requires random seeds) + +### Why ML-DSA-65 as default? + +**192-bit Security (NIST Level 3)**: +- Exceeds Bitcoin's 128-bit security +- Margin for future cryptanalysis advances +- Matches high-value financial applications + +**Performance Balance**: +- 417μs sign time acceptable for transaction throughput +- 108μs verify time suitable for consensus +- 3,293 byte signatures fit in typical network packets + +## Reference Implementation + +### Complete Example + +```go +package main + +import ( + "crypto/rand" + "fmt" + + "github.com/luxfi/crypto/mldsa" +) + +func main() { + // Generate validator key pair + validatorKey, err :=

Root CA certificates use SLH-DSA-SHA2-256s +- Governance proposals support SLH-DSA signatures + +### Phase 2: EVM Integration (Q2 2026) +- Deploy SLH-DSA precompile to C-Chain +- Enable smart contracts to verify SLH-DSA signatures +- On-chain governance using SLH-DSA + +### Phase 3: Diversified Security (Q3 2026) +- Validators can choose ML-DSA (fast) or SLH-DSA (conservative) +- Critical operations require SLH-DSA signatures +- Defense-in-depth with multiple quantum-safe schemes + +## Security Considerations + +### Hash-Based Security + +**Conservative Foundation**: +- Security relies ONLY on hash function collision resistance +- No reliance on hard math problems (no lattices, no elliptic curves) +- Decades of cryptanalysis (Merkle signatures from 1979) +- Resistant to ALL quantum algorithms (including future discoveries) + +**Hash Function Requirements**: +- SHA-256: 128-bit collision resistance → 128-bit security +- SHAKE256: Adjustable output length for 128/192/256-bit security +- Both are NIST-standardized and extensively analyzed + +### Stateless Property + +**Key Advantages**: +- Keys can be safely backed up and copied +- No state synchronization across systems +- Simpler implementation and deployment +- No catastrophic failure if state is lost + +**Comparison to XMSS/LMS**: +- XMSS/LMS are stateful (must track signature counter) +- State loss = key compromise risk +- SLH-DSA eliminates this entire vulnerability class + +### Trade-offs vs ML-DSA + +**SLH-DSA Advantages**: +- More conservative security assumptions +- Resistant to future lattice cryptanalysis breakthroughs +- Simpler security analysis +- Deterministic and stateless + +**SLH-DSA Disadvantages**: +- 2-60x slower signing (10ms - 2s vs 417μs) +- 2-15x larger signatures (7KB - 49KB vs 3KB) +- Higher computational cost for verification + +### Side-Channel Resistance + +**Constant-Time Operations**: +- All hash operations run in constant time +- No secret-dependent branches +- No secret-dependent memory access + +**Implementation Quality**: +- CIRCL library used by Cloudflare in production +- Formal verification of critical components +- Regular security audits + +### Key Management + +**Validator Keys**: +- Generate fresh SLH-DSA keys for critical validators +- Store private keys in HSM when available +- Use SHA2-256s for maximum security assurance + +**Backup & Recovery**: +- SLH-DSA private keys are only 64-128 bytes +- Smaller than ML-DSA keys (4,000 bytes) +- Standard seed-based derivation (BIP-39 compatible) +- Encrypt backups with AES-256 + +## Backwards Compatibility + +**Hybrid Period (2026-2027)**: +- Validators support ML-DSA, SLH-DSA, or both +- Critical operations gradually require SLH-DSA +- Governance proposals support both signature types + +**Legacy Support**: +- ECDSA addresses continue to function +- BLS signatures maintained for consensus +- Gradual transition based on security requirements + +## Rationale + +### Why SLH-DSA over other hash-based schemes? + +**vs XMSS/LMS (stateful)**: +- SLH-DSA is stateless (no state management) +- No risk of key compromise from state loss +- Simpler operational model +- Better for distributed systems + +**vs ML-DSA (lattice-based)**: +- SLH-DSA has more conservative security foundation +- No mathematical assumptions beyond hash functions +- Resistant to future cryptanalytic breakthroughs +- Trade-off: Much larger signatures and slower signing + +**vs Classical Hash Functions**: +- SLH-DSA provides signatures (authentication) +- Hash functions alone only provide integrity +- Merkle tree structure enables efficient verification + +### Why SHA2-128f as default? + +**128-bit Security**: +- Matches current blockchain security standards +- Adequate for most applications +- Future-proof against quantum attacks + +**Fast Signing (f variant)**: +- 10ms signing time acceptable for transactions +- 2x larger signature (17KB vs 7.8KB) acceptable +- Better user experience vs small variants (309ms) + +**SHA2 vs SHAKE**: +- SHA2 has longer history (since 2001) +- Better hardware support and optimization +- SHAKE variants 3-5x slower on current hardware + +### When to use which variant? + +**SHA2-128f (Default)**: +- Standard transactions +- Regular validator operations +- General-purpose signing + +**SHA2-256s (Maximum Security)**: +- Root CA certificates +- Genesis block signatures +- 10+ year security requirements +- Accept 603ms signing time for ultimate security + +**SHA2-192f (Balanced)**: +- High-value transactions +- Important governance proposals +- Balance between security and performance + +## Reference Implementation + +### Complete Example + +```go +package main + +import ( + "crypto/rand" + "fmt" + + "github.com/luxfi/crypto/slhdsa" +) + +func main() { + // Generate critical validator key pair + validatorKey, err := slhdsa.GenerateKey(rand.Reader, slhdsa.SHA2_128f) + if err != nil { + panic(err) + } + + // Sign long-term commitment +

fmt.Printf("Public key: %d bytes\n", len(pubKeyBytes)) + // Output: Public key: 32 bytes + + fmt.Printf("Private key: %d bytes\n", len(privKeyBytes)) + // Output: Private key: 64 bytes +} +``` + +### Governance Proposal Example + +```go +// Sign governance proposal with maximum security +func signGovernanceProposal(proposal []byte) ([]byte, error) { + // Use SHA2-256s for maximum security assurance + sk, err := slhdsa.GenerateKey(rand.Reader, slhdsa.SHA2_256s) + if err != nil { + return nil, err + } + + // Sign proposal (deterministic) + signature, err := sk.Sign(rand.Reader, proposal,

The format supports multiple transaction types including standard transfers, smart contract calls, AI inference requests, and distributed training updates. It implements advanced compression techniques achieving 10-20x reduction in data size, batch aggregation for efficient L1 settlement, and cryptographic commitments for state integrity. The specification includes extensions for cross-rollup communication and quantum-resistant signatures. - -## Activation - -| Parameter | Value | -|--------------------|--------------------------| -| Flag string | `lp505-l2-block-format` | -| Default in code | **false** until block X | -| Deployment branch | `v0.0.0-lp505` | -| Roll‑out criteria | 1M blocks produced | -| Back‑off plan | Legacy format support | - -## Motivation - -Current L2 block formats lack: - -1. **Compression Optimization**: Inefficient data encoding -2. **AI Metadata**: No support for compute workload tracking -3. **Batch Efficiency**: Poor aggregation for L1 submission -4. **Cross-rollup Standards**: Incompatible formats between L2s -5. **Future-proofing**: No quantum-resistant signature support - -This specification provides: -- **90% Size Reduction**: Advanced compression techniques -- **AI-Native Support**: Built-in compute metadata fields -- **Efficient Aggregation**: Optimized for batch submission -- **Interoperability**: Standard format across rollups -- **Quantum Resistance**: Support for post-quantum signatures - -## Specification - -### Core Block Structure - -```solidity -interface IL2BlockFormat { - struct L2Block { - BlockHeader header;

Threshold-signature custody for all externally-bridged assets (BTC Taproot MuSig2, ETH/Arb/OP ECDSA-GG21, XRPL Ed25519-FROST, etc.). -2. SwapSigTx issuance—i.e. deterministic, on-chain proof that the quorum of custodial signers has produced a valid spend-signature for a given SwapTx on X-Chain. -3. Autonomous slashing & reward accounting for MPC signers based on service-level compliance. -4. A light-client proof format (MProof) consumable by X-Chain and Z-Chain without full T-Chain sync. - -This LP formalises the VM, transaction formats, validator duties, RPCs and economic parameters that replace the legacy off-chain bridge back-end (`swaps.ts`) with fully decentralised, auditable on-chain logic. - -## 2 Motivation - -The original Lux Bridge relied on: -- a Postgres "swap" table, -- a central key-manager process, and -- a cron-based status poller. - -These create single points of failure and introduce trust in the server operator. -Migrating signature collection and state tracking into a sovereign chain removes those risks and lets any front-end query or drive swaps by standard JSON-RPC or WebSocket streams. -Validators who already stake LUX now earn additional MPC rewards, tightening economic alignment. - -## 3 High-level Architecture - -```solidity - +---------------------------------------+ - | T-Chain VM | - |---------------------------------------| - | • KeyShareRegistry (G1, G2, PK) | - | • SwapSigTx verifier | - | • SLA / Slashing manager | - | • RewardDistributor | - +------------------+--------------------+ - | - WarpMsg | gRPC /sign_swap(id) - v - +-----------+ +---------------------+ +-----------+ - | X-Chain |<-------| mpckeyd (per signer)|------->| BTC / ETH | - | SwapFx | +---------------------+ | XRPL… | - +-----------+ +-----------+ -``` - -- Each validator must run `mpckeyd`, holding one or more key-shares. -- When an X-Chain `SwapTx` enters PENDING state, validators detect the event through a filtered light-client feed, assemble a threshold signature, and collectively submit `SwapSigTx` on T-Chain. -- Failure to sign before expiry incurs an automated slashing penalty booked by the VM. -- X-Chain trusts T-Chain via a Merkle-mount light-client proof (MProof) – no full sync required. - -## 4 Specification - -### 4.1 Consensus & Validator Set -- **Engine**: Lux consensus++ linear chain (2 s finality). -- **Staking token**: LUX.

-> **See also**: [LP-13](/docs/lp-13-t-chain-decentralised-mpc-custody-and-swap-signature-layer/), [LP-INDEX](/docs/) - -## Abstract - -This proposal introduces a formal design for using the Chase–Gennaro–Goldfeder 2021 (CGG21) threshold signature scheme in Lux’s T-Chain (the MPC-based bridge chain). We expand on LP-13 by providing an academic-style rationale for adopting CGG21, an overview of its node-level integration in Lux’s MVM, comparisons with prior threshold schemes (GG18, DKLS19, and Ethereum’s threshold cryptography efforts), and a detailed threat model with security assumptions. We also outline a roadmap for a hybrid post-quantum upgrade, incorporating a subset of Ringtail (a lattice-based threshold signature scheme) participants into the signing group to achieve partial post-quantum protection during the transition. - -## Motivation and Rationale for CGG21 - -Figure 1: Concept of a threshold signature. A signature is only produced if a threshold of participants collaborate, mitigating single points of failure. - -Threshold signatures allow a private key’s functionality to be distributed among \(n\) parties such that any quorum of \(t\) (threshold) parties can jointly produce a valid signature, whereas any collusion of fewer than \(t\) cannot [9]. This property greatly enhances security for high-value assets and cross-chain bridges by eliminating any single point of key compromise. - -CGG21, formally known as “UC Non-Interactive, Proactive, Threshold ECDSA with Identifiable Aborts,” is a state-of-the-art threshold ECDSA protocol that combines several desirable features [1]: - -- **Non‑interactive signing**: Only the final round depends on the message, while prior rounds can be pre‑computed offline. This yields a low-latency signing process suitable for time-sensitive blockchain operations. In practice, Lux’s T-Chain nodes can perform most of the computation before a signature is requested, so signing adds minimal delay. -- **Few communication rounds**: CGG21 achieves a signing workflow in as few as 5 rounds (or 8 rounds in an alternate variant), significantly fewer than earlier schemes. Lux’s implementation uses the 5‑round variant to minimize latency, incurring a slight computation overhead only if a signing attempt fails. -- **Identifiable aborts (accountability)**: A key innovation of CGG21 is the ability to identify misbehaving parties if the protocol fails. In earlier threshold ECDSA protocols like GG18, any dishonest participant could simply abort the signing, causing a denial-of-service without penalty [2]. CGG21 remedies this by pinpointing the culprit when a signature share is invalid or withheld. This identifiable abort property deters sabotage by enabling Lux to slash or replace malicious nodes—a crucial feature for an open network of validators. -- **Proactive security with key refresh**: The scheme supports periodic distributed key refreshes that do not change the public key but reshuffle the private key shares. This means T-Chain validators can regularly re-randomize their secret shares (e.g., per epoch), so an adversary cannot slowly compromise shares one by one over time. An attacker must corrupt at least \(t\) nodes within one refresh period to break the key, dramatically reducing the risk of key compromise in long-lived signing groups. -- **Dealerless distributed key generation (DKG)**: CGG21 includes a built-in DKG protocol for key-share distribution. Validators jointly generate the ECDSA private key shares without any trusted dealer, and no single node ever knows the full secret key. This aligns with Lux’s decentralization goals—the T-Chain can initialize or reconfigure signer sets transparently on-chain, avoiding any single point of trust during setup. -- **Universally Composable (UC) security**: The protocol is proven secure in the rigorous UC framework (in the Global Random Oracle model), meaning it securely realizes an ideal threshold signature functionality under composition with other protocols. Its security relies on standard cryptographic hardness assumptions: Strong RSA, Decisional Diffie-Hellman (DDH), the semantic security of Paillier encryption, and a strengthened form of ECDSA’s unforgeability assumption. These assumptions are well-studied and give confidence that no efficient attack is known under classical computing. In particular, CGG21’s reliance on Paillier (an additively homomorphic encryption) enables the distributed multiplication needed for ECDSA signing, while zero-knowledge techniques and verifiable secret sharing enforce correctness. - -Overall, adopting CGG21 in Lux’s bridge architecture provides high security and liveness guarantees (“no surprises” signing that either succeeds or identifies a culprit), suitable performance for real-time signing, and strong theoretical foundations [1]. These advantages justify moving beyond the simpler approaches outlined in LP-13 and embracing an academically vetted scheme that is specifically designed for threshold ECDSA (which, unlike Schnorr-based signatures, is notoriously non-trivial to thresholdize). By using CGG21, Lux positions T-Chain’s multi-party signing at the cutting edge of threshold cryptography research, similar to the “threshold wallets” employed by top custodians. - -## Architecture and Implementation in Lux T-Chain MVM - -**System Overview:** In Lux’s T-Chain (the MPC bridge chain), a committee of validators collaboratively controls bridge accounts using threshold signatures. The Lux MVM (Multiverse Virtual Machine) node software incorporates the CGG21 protocol at the networking and consensus layer. Each T-Chain node holds an encrypted share of the ECDSA private key for each asset or blockchain being bridged. Neither the Lux platform nor any single node ever reconstructs the full private key—all operations are done via distributed computation. - -**Key Generation and Management:** When a new signing group is formed (e.g., rotating the bridge key or adding validators), the nodes run CGG21’s distributed key generation sub-protocol [1]. This protocol uses verifiable secret sharing to distribute shares of a fresh ECDSA private key to all \(n\) participants without revealing the key to anyone. Each node \(i\) obtains a private share \(x_i\), and collectively they define a public key \(X = x·G\) on secp256k1 (where \(G\) is the base point). This public key is published on-chain as the address that holds assets or as the trusted signing authority for bridging. The DKG is dealerless aside from network broadcast and produces commitments and proofs to ensure consistency and correctness of shares for all honest parties. - -The MVM stores each node’s key share in a secure enclave or keystore. For additional safety, validators may split each share among an HSM and a backup service. Periodic key refresh is triggered by the protocol or governance: nodes engage in a 3‑round share refresh that outputs new shares for the same key [1]. This proactive refresh must occur frequently enough so that an adversary cannot compromise \(t\) nodes between refreshes. - -**Signing Process:** To initiate a signing (e.g., releasing funds from the bridge), the T-Chain consensus includes a signing request containing the message hash. Signer nodes then execute the CGG21 signing protocol in two phases [1]: - -- **Offline Pre‑processing:** Nodes asynchronously run pre-computation rounds before any message is known, generating ephemeral values and Paillier-encryption commitments. Lux’s MVM implements this as background tasks that produce pre-signature tokens—partly computed signature shares tied to random nonces and commitments. These tokens are stored locally and exchanged over the T-Chain’s p2p network. -- **Online Signing:** Upon receiving the real message, each node independently combines its pre-signature token with the message hash to compute a signature share without further interaction. In the final round, nodes broadcast their shares and combine them to form the standard ECDSA \((r,s)\) signature [1]. This one-round online phase yields very low latency, typically a few network ticks. -- **Abort Handling:** If a node fails or sends an invalid share, CGG21’s identifiable abort feature reveals the culprit via verifiable commitments [1]. Lux logs this event on-chain, enabling slashing or removal of malicious validators. Honest nodes may retry with a fresh token or pause the bridge if the subgroup is too small to satisfy the threshold. - -The MVM leverages deterministic execution and secure channels (e.g., TLS) to orchestrate each CGG21 round, using optimized native libraries for big‑integer and elliptic‑curve operations. Benchmarks show a 5‑round CGG21 signature completes in a few hundred milliseconds on LAN and under a couple of seconds in geo‑distributed settings [1]. - -## Comparison with Other Threshold Schemes - -**GG18 (Gennaro–Goldfeder 2018):** The first fully distributed \(t\)-of-\(n\) ECDSA scheme [2], GG18 introduced Paillier-based MPC and Gilboa/SPDZ multiplication for threshold signing. While groundbreaking, GG18 lacked identifiable aborts and required ~9 rounds for signing. CGG21 builds on GG18 by adding accountability and reducing online rounds to one, at the cost of extra zero-knowledge proofs. - -**DKLS19 (Doerner–Kondi–Lee–Shelat 2019):** An OT-based threshold ECDSA protocol achieving a 5‑round workflow for general \(t\)-of-\(n\) [3]. DKLS19 reduces ciphertext sizes but typically cannot pre-compute rounds offline, resulting in higher online latency than CGG21’s non-interactive signing. - -**Ethereum Threshold Efforts:** The tBTC bridge initially used a GG18 variant and encountered DoS aborts [6]. Its roadmap includes migrating to Schnorr‑based schemes (e.g., FROST/ROAST) to avoid abort issues [10]. Meanwhile, Eth2 DVT uses threshold BLS (trivially aggregated), but ECDSA threshold remains essential for external-chain compatibility. - -CGG21 offers a compelling balance of low latency, accountability, and strong UC security, positioning Lux ahead of existing Ethereum threshold deployments. - -## Security Model and Assumptions - -**Threat Model:** We assume a malicious adversary that can adaptively corrupt up to \(f = t-1\) of \(n\) signer nodes, enabling arbitrary deviations. The network may reorder or delay messages, but will eventually deliver them. No trusted dealer exists—DKG and signing are fully distributed [1]. - -**Security Guarantees:** CGG21 UC‑securely realizes an ideal threshold signature functionality [1]. Forgery requires either breaking ECDSA (discrete logarithm on secp256k1), Paillier semantic security (composite residuosity), Strong RSA, or DDH. A corrupted set of fewer than \(t\) nodes cannot learn the private key or produce a valid signature. - -**Operational Security:** Threshold protocol messages must use authenticated, encrypted channels to prevent spoofing. Validator key shares reside in secure enclaves or HSMs, and audit logs record protocol transcripts. Identifiable aborts and on-chain slashing deter malicious behavior. - -## Future Roadmap: Hybrid Post-Quantum Threshold Upgrade - -To mitigate future quantum threats, Lux plans a hybrid ECDSA/PQ threshold scheme. We will integrate Ringtail—a lattice-based 2‑round threshold signature based on LWE [7]—by augmenting the signer set with a random subset performing PQ signing. - -During an interim phase, each bridge operation will produce both a CGG21 ECDSA signature and a Ringtail PQ signature. The PQ signature serves as a fallback until on-chain enforcement is viable. As validators opt into PQ signing, governance will mandate hybrid signatures, gradually transitioning Lux’s bridge to quantum-resistant security without service interruption. - -## Implementation Status - -The CGG21/CMP protocol is fully implemented and production-ready in the Lux threshold cryptography library: -- Repository: `github.com/luxfi/threshold` -- Package: `protocols/cmp` -- Status: Production-ready with 100% test coverage -- Testing: Zero skipped tests, comprehensive benchmarks -- Features: Complete CGG21 implementation with all sub-protocols - -Related implementations: -- **MPC-LSS** (LP-103): Dynamic resharing capabilities in `protocols/lss` -- **FROST** (LP-104): Schnorr/EdDSA threshold signatures in `protocols/frost` -- **Supporting Libraries**: Paillier encryption, zero-knowledge proofs, MTA protocols - -## Conclusion - -This draft LP specifies the integration of CGG21 threshold ECDSA into Lux's T-Chain, delivering low-latency non-interactive signing, identifiable aborts, proactive key refresh, and strong UC security. Our comparison shows CGG21's advantages over GG18, DKLS19, and early Ethereum threshold deployments. We also chart a path toward hybrid post-quantum threshold signing with Ringtail, ensuring Lux's bridges remain secure against both current and future adversaries. - -The complete implementation is available at `github.com/luxfi/threshold` with comprehensive test coverage and production-ready code. - -## References - -1.

LSS is a foundational threshold signature protocol that enables dynamic resharing - the ability to change the participant set and threshold without changing the public key. This capability is crucial for long-lived systems where validator sets change over time. - -**Enhancement over Original Paper**: While Vishnu's original LSS paper described a trusted dealer setup, our implementation enhances this with a fully distributed key generation (DKG) protocol, eliminating any single point of trust. This makes LSS suitable for trustless environments while maintaining all dynamic resharing capabilities. - -LSS complements the CGG21 (CMP) protocol described in LP-14 by providing a simpler, more flexible approach to threshold signatures with unique dynamic properties not available in ECDSA-based schemes. - -## Motivation and Rationale - -While CGG21/CMP provides state-of-the-art threshold ECDSA with identifiable aborts, there are scenarios where a simpler, more flexible approach is beneficial: - -1. **Dynamic Participant Sets**: LSS uniquely supports changing the set of participants (adding/removing parties) while maintaining the same public key -2. **Threshold Flexibility**: The threshold can be adjusted dynamically without regenerating keys -3. **Protocol Simplicity**: LSS uses straightforward polynomial secret sharing without complex MPC protocols -4. **Foundation for Higher Protocols**: LSS serves as a building block for more complex threshold schemes - -These properties make LSS ideal for: -- Validator rotation in blockchain networks -- Long-lived custody solutions where signers change -- Disaster recovery scenarios requiring participant replacement -- Gradual migration between signer sets - -## Technical Specification - -### Core Concepts - -LSS is based on Shamir's Secret Sharing using polynomial interpolation over a finite field. The key innovation is the resharing protocol that enables dynamic reconfiguration. - -#### Mathematical Foundation - -Given a secret `s` and threshold `t`: -1. Construct a random polynomial `f(x)` of degree `t-1` where `f(0) = s` -2. Each party `i` receives share `f(i)` -3. Any `t` parties can reconstruct `s` using Lagrange interpolation -4. The public key `Y = s·G` remains constant across resharing - -#### Key Properties - -- **Information Theoretic Security**: No computational assumptions required for secrecy -- **Perfect Secrecy**: Fewer than `t` shares reveal nothing about the secret -- **Homomorphic**: Operations on shares correspond to operations on secrets -- **Verifiable**: Using Feldman VSS, shares can be verified without revealing the secret - -### Protocol Phases - -#### 1. Distributed Key Generation (DKG) - -LSS implements fully distributed key generation without any trusted dealer: - -```markdown -Input: Parties P = {p₁, ..., pₙ}, threshold t -Output: Share sᵢ for each party, public key Y - -Round 1 - Polynomial Generation & Commitment: -Each party pᵢ: -1. Generate random secret sᵢ and polynomial fᵢ(x) of degree t-1 where fᵢ(0) = sᵢ -2. Compute commitments Cᵢⱼ = fᵢ(j)·G for each party j -3. Generate chain key for session binding -4. Broadcast commitments to all parties - -Round 2 - Share Distribution: -Each party pᵢ: -1. Verify received commitments from all parties -2. Compute shares sᵢⱼ = fᵢ(j) for each party j -3. Send encrypted share sᵢⱼ to party pⱼ - -Round 3 - Share Aggregation & Verification: -Each party pᵢ: -1. Verify received shares: sⱼᵢ·G ?= Cⱼᵢ -2. Compute final share: xᵢ = Σⱼ sⱼᵢ -3. Compute public key: Y = Σⱼ Cⱼ₀ -4. Store configuration with share xᵢ and public key Y - -Output: Distributed key with no single party knowing the secret -``` - -This DKG protocol ensures: -- **No Trusted Dealer**: Secret is generated collectively -- **Verifiability**: All shares can be verified using commitments -- **Robustness**: Protocol completes despite t-1 malicious parties - -#### 2. Signing - -```markdown -Input: Message m, signers S ⊆ P with |S| ≥ t -Output: Schnorr signature (R, z) - -1. Nonce Generation: - Each signer i ∈ S: - a. Generate random kᵢ - b. Compute Rᵢ = kᵢ·G - c. Broadcast Rᵢ - -2. Aggregation: - a. R = Σᵢ∈S λᵢ·Rᵢ (λᵢ are Lagrange coefficients) - b. c = H(R, Y, m) - -3. Response: - Each signer i: - a. Compute zᵢ = kᵢ + c·λᵢ·sᵢ - b. Broadcast zᵢ - -4. Combine: - z = Σᵢ∈S zᵢ - -5. Output: (R, z) -``` - -#### 3. Dynamic Resharing (Unique to LSS) - -```markdown -Input: Old parties P_old, new parties P_new, new threshold t_new -Output: New shares for P_new, same public key Y - -1. Share Distribution: - Each party pᵢ ∈ P_old: - a. Create polynomial fᵢ(x) where fᵢ(0) = sᵢ_old - b. Compute shares sᵢⱼ = fᵢ(j) for each pⱼ ∈ P_new - c. Send sᵢⱼ to pⱼ with commitments - -2. Share Aggregation: - Each party pⱼ ∈ P_new: - a. Collect shares from t_old parties in P_old - b. Verify shares using commitments - c. Compute new share sⱼ_new = Σᵢ sᵢⱼ - -3. Verification: - a. Verify public key unchanged: Y_new = Y_old - b. Run verification protocol among P_new - -4.

Implementations MUST follow those algorithms and parameter choices. - -## Rationale - -LSS is chosen for its native dynamic resharing: validator sets and thresholds can change without rotating public keys. This simplifies long‑lived operations, reduces operational risk, and complements ECDSA‑focused protocols (CGG21) with a simpler Schnorr‑style alternative. - -## Backwards Compatibility - -This LP introduces an additive threshold scheme. Existing components continue to operate unchanged. Systems MAY adopt LSS gradually; keys and interfaces are versioned via the `Generation` counter to avoid ambiguity during migrations. - -## Security Considerations - -Follow the Security Model above. In particular: use authenticated channels, enforce generation counters to prevent replay, schedule proactive resharing to limit exposure, and verify shares via VSS commitments. Parameter choices (field, hash, encryption) MUST match those stated. -- Supports same key management infrastructure -- Uses common networking and storage layers - -### Migration Path - -For systems currently using static threshold schemes: -1. Generate LSS shares for existing key -2. Run parallel signing during transition -3. Gradually rotate out old system -4.

CGGMP21 is a state-of-the-art threshold signature protocol providing UC-security (Universal Composability) with **identifiable aborts**, enabling detection and penalization of malicious parties.

CGGMP21 Protocol Selection**: The CGGMP21 protocol was chosen over older threshold ECDSA schemes due to: -- UC (Universally Composable) security proofs under malicious adversaries -- Optimal round complexity (4 rounds for signing) -- Identifiable abort capability for detecting malicious participants -- Support for arbitrary threshold t-of-n configurations - -**2. Precompile vs. Native Transaction Type**: Implementing as a precompile rather than a new transaction type provides: -- Composability with existing smart contracts -- Simpler integration for wallet developers -- Gas-metered access for predictable costs -- No consensus layer changes required - -**3. On-Chain Key Generation**: DKG as a precompile enables: -- Trustless key generation without off-chain coordination -- Transparent dealer-free setup -- Verifiable key share distribution -- Integration with smart contract governance - -**4. Proactive Security (Key Refresh)**: The key refresh mechanism provides: -- Forward secrecy for long-lived keys -- Recovery from partial compromise -- Ability to change threshold without changing public key - -### Alternatives Considered - -- **GG18/GG20**: Earlier protocols lack identifiable abort, making debugging failures difficult -- **FROST**: Schnorr-based, requires different curve; not ECDSA compatible -- **Shamir-based TSS**: Requires trusted dealer; no malicious security -- **Off-chain MPC**: Introduces availability and censorship concerns - -## Security Considerations - -### Threshold Selection - -Choose threshold based on security requirements: - -| Use Case | Recommended Threshold | Rationale | -|----------|----------------------|-----------| -| Personal Wallet | 2-of-3 | Simple backup, low overhead | -| Small DAO | 3-of-5 | Standard governance, reasonable security | -| Trading Firm | 5-of-7 | High security, operational flexibility | -| Institutional Custody | 7-of-10+ | Enterprise security, compliance | -| Validator Networks | 2/3 majority | Byzantine fault tolerance | - -### Key Management Best Practices - -1. **Geographic Distribution**: Store shares in different locations -2. **Hardware Security**: Use HSMs for institutional custody -3. **Regular Refresh**: Periodically refresh shares for forward security -4. **Backup Strategy**: Securely backup threshold shares -5. **Monitoring**: Track abort events to detect attacks -6. **Slashing**: Penalize parties identified in aborts - -### Message Hashing - -Always use domain separation in message hashing: - -```solidity -bytes32 domainSeparator = keccak256(abi.encodePacked( - "EIP712Domain", - keccak256("CGGMP21-v1"), - keccak256(abi.encodePacked(address(this))), - block.chainid -)); - -bytes32 messageHash = keccak256(abi.encodePacked( - "\x19\x01", - domainSeparator, - keccak256(abi.encode(nonce, data)) -)); -``` - -### Identifiable Abort Handling - -When an abort is identified: - -1. **Log Event**: Emit event with malicious party identifier -2. **Slash Stake**: If validator, slash their stake -3. **Blacklist**: Temporarily or permanently exclude from signing -4. **Forensics**: Preserve proof data for investigation -5. **Recovery**: Restart signing without malicious party - -### Secure Implementation Guidelines - -#### Cryptographic Requirements - -**Paillier Key Generation** (critical for ECDSA threshold): -```go -// ~/work/lux/threshold/pkg/paillier/keygen.go -// MUST use safe primes p, q where p = 2p' + 1, q = 2q' + 1 -// Key size MUST be ≥ 2048 bits for 128-bit security -const ( - MinKeyBits = 2048 // Minimum Paillier modulus size - SecureKeyBits = 3072 // Recommended for long-term security -) - -// Generate safe primes with proper entropy -func GenerateSafePrime(bits int, rand io.Reader) (*big.Int, error) { - // Uses crypto/rand, NOT math/rand - // Verified primality with Miller-Rabin + Lucas -} -``` - -**Zero-Knowledge Proof Security**: -```go -// ~/work/lux/threshold/pkg/zk/ - All 17 proof systems -// Each proof MUST be: -// 1.

LSS-MPC enables live expansion and contraction of signing groups (transitioning from T-of-N to T'-of-(N±k) participants) **without reconstructing the master secret key**. This extension is compatible with CGGMP21 (ECDSA threshold), FROST (Schnorr/EdDSA threshold), and other threshold signature schemes. - -**Important:** LSS-MPC is NOT a signature scheme itself—it is an **extension layer** that adds dynamic resharing capabilities to existing threshold protocols. - -## Motivation - -### Operational Challenges in Threshold Systems - -Traditional threshold signature schemes face critical operational limitations: - -1. **Static Groups**: Participant sets are locked at key generation -2. **Insecure Key Rotation**: Requires full secret reconstruction (security risk) -3. **No Scaling**: Cannot add/remove parties without downtime -4. **No Proactive Security**: Cannot refresh keys without service interruption - -### LSS-MPC Solution - -LSS-MPC provides sophisticated dynamic resharing capabilities: - -1. **Live Membership Changes**: Transition from T-of-N to T'-of-(N±k) without downtime -2. **Zero Key Reconstruction**: Master secret never reassembled during resharing -3. **Proactive Security**: Regular key refreshing without reconstruction -4. **Protocol Agnostic**: Works with CGGMP21, FROST, EdDSA, and lattice-based schemes - -### Real-World Use Cases - -#### Validator Set Management -- **Problem**: PoS validators join/leave network dynamically -- **LSS Solution**: Reshare validator signing key without network pause -- **Impact**: Continuous block production during validator rotation - -#### Cross-Chain Bridges -- **Problem**: Bridge guardians change over time -- **LSS Solution**: Update guardian set without reconstructing bridge key -- **Impact**: No bridge downtime, maintained security - -#### Institutional Custody -- **Problem**: Employee turnover requires key policy changes -- **LSS Solution**: Add/remove signers without re-keying all wallets -- **Impact**: Operational efficiency, reduced risk -

- No party learns full key - - t-security maintained throughout -``` - -#### Four-Step Protocol (Section 4 of LSS Paper) - -**Step 1: Auxiliary Secret Generation** -All parties generate shares for temporary secrets `w` and `q` via Joint Verifiable Secret Sharing (JVSS): -```solidity -w ← random, degree t'-1 polynomial -q ← random, degree t'-1 polynomial -All parties receive w_i and q_j shares -``` - -**Step 2: Blinded Secret Computation** -Original parties compute blinded secret `a·w` using interpolation: -```markdown -Each old party i: computes a_i · w_i -Interpolate using Lagrange: a·w = Σ(λ_i · a_i · w_i) -``` - -**Step 3: Inverse Blinding** -Compute `z = (q·w)^(-1)` and distribute shares: -```markdown -Interpolate q·w = Σ(λ_j · q_j · w_j) -Compute z = (q·w)^(-1) -Create z_j shares for each new party j -``` - -**Step 4: Final Share Derivation** -Each new party computes their share: -```solidity -a'_j = (a·w) · q_j · z_j - -Verification: Lagrange interpolation of {a'_j} = a (original secret) -``` - -### Interface Specifications -

-## Integration with Base Protocols - -### LSS + CGGMP21 (ECDSA) - -CGGMP21 provides UC-secure ECDSA threshold signatures. LSS extends it with: - -**Core CGGMP21 Features:** -- 5-round threshold ECDSA signing -- Identifiable abort on malicious parties -- Refresh protocol for proactive security -- Non-interactive preprocessing - -**LSS Enhancements:** -- Dynamic validator set rotation (add/remove signers) -- Live threshold policy changes -- Horizontal scaling (expand MPC cluster) -- Zero-downtime key management - -**Use Case:** Ethereum validator managed custody -```markdown -Initial: 3-of-5 institutional signers -After 1 year: Add 2 signers → 4-of-7 (new policy) -After 2 years: Remove founding signer → 4-of-6 -All without reconstructing Ethereum validator key -``` - -### LSS + FROST (Schnorr/EdDSA) - -FROST provides 2-round Schnorr threshold signatures. LSS extends it with: - -**Core FROST Features:** -- 2-round signing (optimal) -- Deterministic nonces -- Compatible with Ed25519, secp256k1 -- Simple verification - -**LSS Enhancements:** -- Bitcoin Taproot key rotation (musig → threshold) -- Solana validator key updates -- Lightning Network channel key management -- Proactive share refreshing - -**Use Case:** Bitcoin Taproot multisig bridge -```markdown -Initial: 5-of-8 bridge guardians -Guardian rotation: 5-of-9 (add 1, remove 1) -Emergency: 7-of-9 (increase security threshold) -All without moving Bitcoin from Taproot address -``` - -## Security Properties - -### Threshold Security - -**Cryptographic Guarantees:** -1. **T-Security**: No coalition of < T parties can forge signatures -2. **Key Privacy**: No coalition of < T parties learns any information about master key -3. **Resharing Security**: Security maintained during and after resharing -4. **Forward Security**: Compromised old shares cannot be used after resharing - -**Adversary Models:** -- **Static Adversary**: Adversary chooses corrupt parties before protocol starts -- **Mobile Adversary**: Adversary can slowly corrupt parties over time (LSS prevents this) -- **Malicious Adversary**: Byzantine parties can deviate arbitrarily from protocol - -### Resharing Security Theorem - -**Theorem (LSS Paper, Section 4):** - -Let Π be a (t,n)-threshold signature scheme with security parameter λ. The LSS dynamic resharing protocol produces a (t',n')-threshold scheme Π' such that: - -1. **Correctness**: Any t' parties from Π' can reconstruct the same master secret as any t parties from Π -2. **Privacy**: An adversary corrupting < t' parties in Π' learns nothing about the master secret -3. **Non-Reconstruction**: At no point during resharing is the master secret reconstructed - -**Security Proof:** The protocol uses blinding with random polynomials w and q such that: -- `a·w` is uniformly random (information-theoretically secure) -- `(q·w)^(-1)` removes blinding without revealing `a` -- Final shares `a'_j = (a·w)·q_j·z_j` are valid Shamir shares of `a` - -### Trust Model - -**Coordinator Roles:** -1. **Bootstrap Dealer**: Orchestrates JVSS for auxiliary secrets `w` and `q` - - Trusted for: Liveness (protocol coordination) - - NOT trusted for: Secrecy (never sees `a`, `w`, `q` in plaintext) - -2. **Signature Coordinator**: Manages signing operations and rollback - - Trusted for: Liveness (collecting partial signatures) - - NOT trusted for: Secrecy (never learns shares) - -**Participant Trust:** -- Honest majority assumption: < t parties are corrupt -- Byzantine tolerance: Protocol detects and aborts on cheating -- Identifiable abort: Malicious parties can be identified - -### Proactive Security - -LSS enables **proactive security** - regular share refreshing defeats slow key compromise: - -**Attack Scenario Without LSS:** -```markdown -Year 0: Adversary compromises 1 share -Year 1: Compromises 1 more share -Year 2: Compromises 1 more share (reaches threshold t=3) -Result: Master key compromised -``` - -**Defense With LSS (Monthly Resharing):** -```markdown -Year 0: Adversary compromises 1 share -Month 1: Reshare → old shares useless -Year 1: Adversary compromises 1 share (new generation) -Month 13: Reshare → old shares useless -Result: Adversary never reaches threshold -``` - -**Recommended Resharing Schedule:** -- **High-security systems**: Weekly or monthly -- **Standard systems**: Quarterly or biannually -- **Low-security systems**: Annually - -## Performance Characteristics -

-**Performance Analysis:** -- **Linear Scaling**: Resharing time scales linearly with party count -- **Fast Operations**: Sub-50ms resharing for typical configurations -- **High Throughput**: Suitable for production validator rotation -- **Efficient Rollback**: Rapid recovery from failed resharing - -### Complexity Analysis - -**Communication Rounds:** -- JVSS for `w` and `q`: O(1) rounds (broadcast commitments + responses) -- Blinded secret computation: O(1) rounds (threshold old parties interpolate) -- Share distribution: O(1) rounds (coordinator distributes encrypted shares) -- **Total: O(1) rounds** (constant, independent of n) - -**Message Complexity:** -- JVSS commitments: O(n') messages -- JVSS responses: O(n') messages -- Encrypted share distribution: O(n') messages -- **Total: O(n') messages** (linear in new party count) -

-**LSS Advantages:** -1. **Zero Downtime**: Signing continues during resharing -2. **No Key Reconstruction**: Master secret never reassembled (critical security property) -3. **Flexible Policies**: Change threshold and participants independently -4. **Proactive Security**: Regular resharing defeats mobile adversaries - -**When LSS is Essential:** -- **24/7 Services**: Validator signing, bridge custody -- **High-Security Systems**: Cannot tolerate key reconstruction risk -- **Dynamic Environments**: Frequent membership changes -- **Regulatory Compliance**: Proactive key rotation requirements - -### Design Decisions - -#### Coordinator-Driven vs Peer-to-Peer - -**Chosen: Coordinator-Driven** - -**Rationale:** -- Simpler liveness guarantees (single orchestrator) -- Easier state synchronization -- Coordinator is trusted for liveness, NOT secrecy -- Suitable for institutional deployment models - -**Trade-off:** Single point of failure for liveness (not security) - -**Mitigation:** Coordinator can be replicated for high availability - -#### JVSS for Auxiliary Secrets - -**Chosen: Joint Verifiable Secret Sharing (JVSS)** - -**Rationale:** -- Provides verifiability (parties can verify share correctness) -- Non-interactive commitment phase -- Compatible with standard Shamir secret sharing -- Well-studied cryptographic primitive - -**Alternatives Considered:** -- **Feldman VSS**: Requires discrete log assumption (less general) -- **Pedersen VSS**: More complex, computationally hiding - -#### Blinding Technique - -**Chosen: Multiplicative Blinding with Random Polynomials** - -**Rationale:** -- Information-theoretically secure (unconditional security) -- Composable with standard secret sharing -- Efficient computation (scalar multiplications) -- Proven secure in LSS paper - -**How It Works:** -```markdown -Blind: a·w (random w masks a) -Inverse blind: (q·w)^(-1) (removes w without revealing a) -Final share: a'_j = (a·w)·q_j·z_j where z = (q·w)^(-1) -``` - -## Backwards Compatibility -

Multi-Provider Architecture**: Supporting 8 HSM providers ensures validators can choose solutions matching their security requirements, compliance needs, and budget constraints. No vendor lock-in. - -**2. Unified Interface**: A single KMS API across all providers simplifies integration and allows seamless migration between HSM backends without code changes. - -**3. Plugin Architecture**: HSM providers are loaded as plugins, enabling community-contributed backends and custom integrations for specialized hardware. - -**4. Hardware Abstraction**: The KMS layer abstracts hardware-specific details, allowing the same validator code to run against SoftHSM (development) and enterprise HSMs (production). - -### Alternatives Considered - -- **Single Provider**: Rejected as it creates vendor lock-in and limits deployment options -- **Direct HSM Integration**: Rejected due to complexity; each HSM vendor has different APIs -- **Software-only**: Rejected for production use; HSMs provide tamper resistance and key isolation -- **Threshold Signatures Only**: Rejected as some use cases require single-key operations - -## Backwards Compatibility - -This LP introduces new infrastructure without breaking existing validator deployments: - -- **Existing Validators**: Can continue using file-based keys; KMS is opt-in -- **Migration Path**: Validators can gradually migrate keys to HSM without downtime -- **API Compatibility**: KMS interface is additive; existing signing APIs remain unchanged -- **Configuration**: New KMS config section in validator config files - -## Security Considerations - -### Key Isolation - -- Private keys never leave HSM boundary in hardware-backed deployments -- Memory isolation prevents key extraction even with root access -- Side-channel resistant operations in compliant HSMs - -### Audit and Compliance - -- FIPS 140-2 Level 3 certification available with enterprise HSMs -- Key usage audit logs for compliance reporting -- Role-based access control for multi-operator setups - -### Backup and Recovery - -- Secure key backup with split-secret schemes -- Recovery procedures require multi-party authorization -- Hardware redundancy recommendations in documentation - -### Attack Vectors - -- Physical tampering detected by HSM zeroization -- Network isolation recommended for HSM interfaces -- Regular firmware updates for security patches - -## Test Cases - -### Unit Tests - -```go -func TestKMSProviderInitialization(t *testing.T) { -

-## Abstract - -This LP specifies the T-Chain (Threshold Chain), Lux Network's dedicated blockchain for threshold cryptography operations. T-Chain implements the ThresholdVM, a purpose-built virtual machine that manages distributed key shares using Linear Secret Sharing (LSS), supports both CGGMP21 threshold ECDSA and FROST threshold Schnorr signatures, and enables dynamic signer rotation without key reconstruction. Each validator node holds a share of managed keys, ensuring no single party ever possesses the complete private key. T-Chain provides threshold signature services to B-Chain (BridgeVM), T-Chain (MPC custody), and other Lux chain consumers requiring distributed signing authority. - -## Activation - -| Parameter | Value | -|--------------------|--------------------------| -| Flag string | `lp330-t-chain` | -| Default in code | **false** until block 0 | -| Deployment branch | `v1.0.0-lp330` | -| Roll-out criteria | Genesis activation | -| Back-off plan | Disable via config flag | - -## Conformance - -The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119](https://www.rfc-editor.org/rfc/rfc2119) and [RFC 8174](https://www.rfc-editor.org/rfc/rfc8174). - -### Conformance Levels - -Implementations of this specification fall into three conformance levels: - -| Level | Requirements | -|-------|--------------| -| **Core** | MUST implement all transaction types (KeyGenTx, SignRequestTx, SignResponseTx, ReshareTx, ReshareCompleteTx, KeyRotateTx, RefreshTx). MUST support at least CGGMP21_ECDSA algorithm. | -| **Extended** | MUST meet Core requirements. MUST implement FROST_SCHNORR and FROST_EDDSA protocols. MUST support BIP-340 Taproot signatures. | -| **Full** | MUST meet Extended requirements. MUST implement all RPC API endpoints. MUST support WebSocket subscriptions. SHOULD implement HSM integration. | - -### Normative Requirements Summary - -1. Implementations MUST validate all threshold configurations against the constraints defined in `ThresholdConfig.Validate()`. -2. Implementations MUST verify that public keys remain unchanged during resharing operations. -3. Implementations MUST use authenticated channels (TLS with mutual authentication) for all signer communication. -4. Implementations MUST implement identifiable abort for Byzantine signer detection. -5. Implementations SHOULD implement proactive share refresh at intervals not exceeding `MaxKeyAge` blocks. -6. Implementations MAY support additional signature algorithms beyond those specified, provided they maintain security guarantees equivalent to CGGMP21 or FROST. - -## Motivation - -### Problem Statement - -Threshold cryptography is fundamental to secure cross-chain bridges, decentralized custody, and distributed signing. Current implementations face several challenges: - -1. **Key Centralization Risk**: Traditional bridge architectures rely on centralized key management, creating single points of failure -2. **Static Signer Sets**: Most threshold schemes require complete key regeneration when signers change, causing operational disruption -3. **Protocol Fragmentation**: Different signature schemes (ECDSA, Schnorr, EdDSA) require separate infrastructure -4. **Signature Coordination Overhead**: Managing signing sessions across validators requires dedicated state machine logic -5. **Share Leakage Over Time**: Without proactive refresh, an adversary accumulating shares can eventually reconstruct keys - -### Solution: Dedicated Threshold Chain - -T-Chain addresses these challenges by providing: - -1. **Isolated Threshold State**: Dedicated chain for key management eliminates competition for block space -2. **Dynamic Resharing**: LSS-based protocol enables signer rotation without public key changes -3. **Multi-Protocol Support**: Unified infrastructure for CGGMP21 (ECDSA) and FROST (Schnorr/EdDSA) -4. **On-Chain Session Management**: Consensus-backed signing coordination with deterministic outcomes -5. **Proactive Security**: Automatic share refresh limits adversary accumulation windows - -### Use Cases - -- **B-Chain Bridge Custody**: Threshold control of bridge vault addresses -- **T-Chain Swap Signatures**: Distributed signing for cross-chain swaps -- **DAO Treasury Management**: Multi-party control of protocol funds -- **Validator Key Rotation**: Seamless transition between validator sets -- **Cross-Chain Oracle Signing**: Threshold attestation for oracle data - -## Specification - -### Chain Architecture - -T-Chain is a specialized Lux chain running the ThresholdVM: - -```solidity -+-------------------------------------------------------------------------+ -| T-Chain Architecture | -+-------------------------------------------------------------------------+ -| | -| +-------------------+ +-------------------+ +------------------+ | -| | External | | T-Chain Core | | Consumers | | -| | Requests | | | | | | -| +-------------------+ +-------------------+ +------------------+ | -| | SignRequest | | ThresholdVM | | B-Chain Bridge | | -| | KeyGenRequest | | LSS Key Manager | | T-Chain MPC | | -| | ReshareRequest | | Session Orchestr. | | DAO Contracts | | -| | RefreshRequest | | Signature Agg. | | Oracle Services | | -| +-------------------+ +-------------------+ +------------------+ | -| | | ^ | -| v v | | -| +-------------------------------------------------------------------+ | -| | Validator Signer Network | | -| +-------------------------------------------------------------------+ | -| | Node A (Share A) | Node B (Share B) | Node C (Share C) | ... | | -| | CGGMP21 + FROST | CGGMP21 + FROST | CGGMP21 + FROST | | | -| +-------------------------------------------------------------------+ | -| | -+-------------------------------------------------------------------------+ -``` - -### Core Components - -#### 1.

-## Security Analysis: Threshold-Specific Threat Vectors - -This section analyzes threat vectors specific to threshold signature schemes beyond the general security model. - -### T1: Adaptive Adversary Share Accumulation - -**Threat**: An adversary corrupts different parties over time, accumulating shares across key generations. - -**Analysis**: If adversary corrupts parties {P1, P2} in generation g1, then {P3, P4} in generation g2, they may hold shares that together exceed the threshold. - -**Mitigation**: -- Proactive refresh MUST be performed at regular intervals (RECOMMENDED: every 43,200 blocks / ~1 day) -- Refresh invalidates all previous-generation shares -- Implementations MUST track share generation numbers -- Cross-generation share reconstruction MUST fail - -```go -// Share generation binding -type BoundShare struct { - Share *big.Int - Generation uint32 - KeyID KeyID -} - -func (s *BoundShare) Verify(expectedGen uint32) error { - if s.Generation != expectedGen { - return ErrGenerationMismatch // Prevents cross-gen attacks - } - return nil -} -``` - -### T2: Rogue Key Attack on FROST DKG - -**Threat**: Malicious party chooses their polynomial coefficients after seeing honest parties' commitments, biasing the resulting public key. - -**Analysis**: In FROST DKG Round 1, if an adversary waits to see all commitments before submitting theirs, they can compute coefficients that result in a public key with a known discrete log relationship to another key they control. - -**Mitigation**: -- FROST DKG MUST use a commit-then-reveal structure -- Round 1 MUST collect hashed commitments H(C_i) before revealing C_i -- Implementations MUST reject late submissions -- Proof of knowledge MUST bind the commitment - -```go -// Rogue key prevention via commit-reveal -type DKGCommitReveal struct { - // Phase 1: Submit hash - CommitHash [32]byte // H(commitment || decommit_key) - - // Phase 2: Reveal (after all hashes collected) - Commitment []byte - DecommitKey [32]byte - - // Proof of knowledge prevents rogue key - ProofOfKnowledge *SchnorrProof -} -``` - -### T3: Nonce Reuse in Threshold ECDSA - -**Threat**: If the same nonce k is used for two different messages, the private key can be recovered. - -**Analysis**: Given signatures (r, s1) and (r, s2) on messages m1 and m2 with same nonce: -``` -k = (m1 - m2) / (s1 - s2) mod n -x = (s1 * k - m1) / r mod n -``` - -**Mitigation**: -- CGGMP21 MUST use pre-signed nonces computed during keygen -- Each nonce MUST be bound to a specific session ID -- Implementations MUST track used nonces and reject duplicates -- Nonces MUST be derived deterministically from session entropy - -```go -// Nonce binding prevents reuse -type BoundNonce struct { - Nonce *big.Int - SessionID SessionID - KeyID KeyID - Used bool -} - -func (n *BoundNonce) MarkUsed() error { - if n.Used { - return ErrNonceAlreadyUsed - } - n.Used = true - return nil -} -``` - -### T4: Grinding Attack on Session ID Selection - -**Threat**: Adversary manipulates session ID generation to produce IDs that bias signing outcomes. - -**Analysis**: If session IDs are not properly randomized, an adversary might generate many candidate sessions and select one with favorable properties. - -**Mitigation**: -- Session IDs MUST include contributions from multiple parties -- Session ID = H(request_hash || block_hash || participant_nonces) -- No single party can control the session ID -- Implementations SHOULD use commit-reveal for participant nonces - -### T5: Denial of Service via Signing Queue Flooding - -**Threat**: Adversary submits many signature requests to exhaust signer resources. - -**Analysis**: Each signing session requires signers to perform expensive operations. An adversary with sufficient funds could degrade service quality. - -**Mitigation**: -- Base fee MUST be economically significant (0.1 LUX minimum) -- Dynamic fee market SHOULD increase fees under load -- Per-key rate limiting MUST be enforced (RECOMMENDED: 10 requests/block) -- Signer resource quotas MUST be implemented - -```go -// Rate limiting per key -type RateLimiter struct { - RequestsPerBlock map[KeyID]uint32 - MaxPerBlock uint32 // Default: 10 -} - -func (r *RateLimiter) Allow(keyID KeyID, block uint64) bool { - count := r.RequestsPerBlock[keyID] - if count >= r.MaxPerBlock { - return false - } - r.RequestsPerBlock[keyID]++ - return true -} -``` - -### T6: Sybil Attack on Signer Selection - -**Threat**: Adversary creates multiple signer identities to gain disproportionate influence in key generation. - -**Analysis**: If signer selection is based purely on stake, an adversary with N * MinStake could control N signer slots. - -**Mitigation**: -- Minimum stake MUST be set high enough to limit Sybil economics (10,000 LUX) -- Signer selection SHOULD incorporate performance history -- Geographic and organizational diversity SHOULD be considered -- Maximum keys per signer MUST be enforced (50 keys) - -### Security Parameter Requirements - -| Parameter | Minimum | Recommended | Maximum | -|:----------|:--------|:------------|:--------| -| Threshold (t) | 2 | n/2 + 1 | n - 1 | -| Total Parties (n) | 3 | 7-15 | 100 | -| Refresh Interval | 21,600 blocks | 43,200 blocks | 86,400 blocks | -| Session Timeout | 100 blocks | 300 blocks | 600 blocks | -| Min Signer Stake | 1,000 LUX | 10,000 LUX | - | - -## Interoperability - -This section defines how T-Chain interoperates with other Lux chains and external systems. - -### T-Chain to B-Chain Integration - -T-Chain provides threshold signatures to B-Chain (BridgeVM) for cross-chain asset custody. Communication occurs via Lux Warp Messaging. - -``` -+-------------+ Warp Message +-------------+ -| B-Chain | --------------------> | T-Chain | -| (BridgeVM) | SignRequest | (ThresholdVM| -+-------------+ +-------------+ - ^ | - | Warp Message | - +--------- SignatureResult -----------+ -``` - -**Request Flow**: -1. B-Chain BridgeVM constructs withdrawal message -2. B-Chain submits `SignRequest` via Warp to T-Chain -3. T-Chain validates request and initiates signing session -4. T-Chain returns signature via Warp callback -5. B-Chain uses signature to release assets on external chain - -**RPC Endpoint**: `http://localhost:9630/ext/bc/T/rpc` - -```go -// B-Chain to T-Chain signature request -type BridgeSignRequest struct { - // Warp routing - SourceChain ids.ID // B-Chain ID - DestChain ids.ID // T-Chain ID - - // Signature parameters - KeyID KeyID - MessageHash [32]byte - MessageType MessageType - - // Callback - CallbackID RequestID - Deadline uint64 -} - -// T-Chain to B-Chain response -type BridgeSignResponse struct { - RequestID RequestID - Signature []byte // DER or raw format - SignerSet []party.ID // Who signed - Success bool - Error string // If failed -} -``` - -### T-Chain to K-Chain Integration - -K-Chain (KeyManagementVM) stores key metadata and access control policies. T-Chain queries K-Chain for authorization decisions. - -```solidity -+-------------+ Query Policy +-------------+ -| T-Chain | --------------------> | K-Chain | -| (ThresholdVM| | (KeyMgmtVM)| -+-------------+ +-------------+ - ^ | - | Authorization | - +----------- Response ---------------+ -``` - -**Authorization Flow**: -1. T-Chain receives `SignRequest` for key K -2. T-Chain queries K-Chain: "Can requester R sign with key K?" -3. K-Chain evaluates policies (rate limits, time windows, amount limits) -4. K-Chain returns authorization decision -5. T-Chain proceeds or rejects based on decision - -```go -// K-Chain authorization query -type AuthorizationQuery struct { - KeyID KeyID - Requester Address - Operation string // "sign", "reshare", "rotate" - Context AuthContext -} - -type AuthContext struct { - Amount *big.Int // For amount-limited keys - Destination Address // For destination-limited keys - Timestamp uint64 -} - -type AuthorizationResponse struct { - Allowed bool - Reason string - RateLimit *RateLimitStatus - Expiry uint64 // Authorization expires at block -} -``` - -### T-Chain to T-Chain Integration - -T-Chain (MultisigVM) can delegate signing authority to T-Chain for operations requiring threshold signatures. - -**Delegation Pattern**: -1. T-Chain multisig approves operation -2. T-Chain submits to T-Chain as authorized requester -3. T-Chain verifies T-Chain signature on request -4. T-Chain performs threshold signing -5. Result returned to T-Chain for execution - -### External Chain Integration - -T-Chain signatures are consumed by smart contracts on external chains (Ethereum, Bitcoin, Solana, etc.). - -**Ethereum Integration**: -```solidity -// Solidity interface for T-Chain signature verification -interface ITChainVerifier { - // Verify ECDSA signature from T-Chain - function verifyTChainSignature( - bytes32 keyId, - bytes32 messageHash, - bytes calldata signature - ) external view returns (bool); - - // Get T-Chain public key for a key ID - function getTChainPublicKey( - bytes32 keyId - ) external view returns (bytes memory); -} -``` - -**Bitcoin Taproot Integration**: -```solidity -T-Chain FROST signature -> 64-byte Schnorr signature - -> Taproot witness spend - -> Bitcoin transaction broadcast -``` - -### Cross-Chain Message Format - -Messages between chains use a standardized envelope: - -```go -type CrossChainMessage struct { - Version uint8 - SourceChain ids.ID - DestChain ids.ID - Nonce uint64 - Payload []byte - Signature []byte // BLS aggregate from source chain validators -} -``` - -### Interoperability Requirements - -1. T-Chain MUST accept Warp messages from registered consumer chains (B-Chain, T-Chain) -2. T-Chain MUST validate Warp message signatures before processing -3. T-Chain MUST return signatures in format compatible with destination chain -4. External chain integrations MUST verify T-Chain signatures match registered public keys -5. Rate limits SHOULD be enforced per source chain - -## Rationale - -### Why Dedicated T-Chain? - -1. **Isolation**: Threshold operations require careful state management; dedicated chain prevents interference -2. **Specialization**: ThresholdVM optimized for cryptographic operations, not general computation -3. **Security Boundary**: Clear separation between signing logic and application logic -4. **Resource Guarantee**: No competition for block space with other applications - -### Why Per-Key Threshold Configuration? - -Different use cases require different security profiles: - -| Use Case | Recommended | Rationale | -|----------|-------------|-----------| -| Bridge vault ($1B+) | 11-of-15 | Maximum security, can tolerate 4 offline | -| DAO treasury | 5-of-7 | Balance security/usability | -| Hot wallet | 2-of-3 | Fast signing, limited exposure | -| Oracle signing | 7-of-10 | Byzantine fault tolerance | - -Global threshold would force one-size-fits-all, reducing flexibility. - -### Why LSS for Resharing? - -Alternatives considered: - -1. **Full Key Regeneration**: Requires new public key, breaking existing integrations -2. **Proactive Secret Sharing**: Only refreshes shares, doesn't change signer set -3. **Additive Resharing**: Limited to adding parties, not removing - -LSS provides: -- Same public key across generations -- Both addition and removal of parties -- Threshold can be adjusted -- Information-theoretic security - -### Why Support Both CGGMP21 and FROST? - -| Chain | Signature | Protocol | -|-------|-----------|----------| -| Ethereum | ECDSA | CGGMP21 | -| Bitcoin | Schnorr (Taproot) | FROST | -| Solana | EdDSA | FROST | -| Cosmos | Secp256k1 | CGGMP21 | - -Supporting both protocols enables T-Chain to serve as universal threshold service for all major chains. - -## Backwards Compatibility - -T-Chain is a new chain; no backwards compatibility concerns. - -### Integration with Existing Chains - -- **B-Chain**: Uses T-Chain for bridge vault signatures via Warp messaging -- **T-Chain**: Uses T-Chain for swap signatures -- **C-Chain**: Contracts can request signatures via T-Chain precompile - -### Migration from T-Chain MPC - -Existing T-Chain MPC operations can migrate to T-Chain: - -1. Register existing keys on T-Chain via `KeyGenTx` with known public keys -2. Run parallel signing during transition -3. Update consumers to use T-Chain RPC -4. Deprecate T-Chain MPC endpoints - -## Test Cases - -### Unit Tests - -```go -func TestKeyGeneration(t *testing.T) { - // Test 3-of-5 CGGMP21 key generation - parties := []party.ID{"p1", "p2", "p3", "p4", "p5"} - threshold := 3 - - config, err := tchain.GenerateKey( - "test-key", - CGGMP21_ECDSA, - SECP256K1, - threshold, - parties, - ) - require.NoError(t, err) - require.Len(t, config.PartyIDs, 5) - require.Equal(t, 3, config.Threshold) - - // Verify public key is valid secp256k1 point - require.True(t, secp256k1.IsOnCurve(config.PublicKey)) -} - -func TestThresholdSigning(t *testing.T) { - // Setup 3-of-5 key - key := setupTestKey(t, 5, 3) - message := sha256.Sum256([]byte("test message")) - - // Sign with exactly threshold parties - signers := key.PartyIDs[:3] - sig, err := tchain.Sign(key.KeyID, message[:], signers) - require.NoError(t, err) - - // Verify signature - valid := ecdsa.Verify(key.PublicKey, message[:], sig) - require.True(t, valid) - - // Sign with fewer than threshold should fail - _, err = tchain.Sign(key.KeyID, message[:], key.PartyIDs[:2]) - require.Error(t, err) - require.Contains(t, err.Error(), "insufficient signers") -} - -func TestDynamicResharing(t *testing.T) { - // Initial 3-of-5 - key := setupTestKey(t, 5, 3) - originalPubKey := key.PublicKey - - // Reshare to 4-of-7 with partial overlap - newParties := []party.ID{"p1", "p2", "p6", "p7", "p8", "p9", "p10"} - newKey, err := tchain.Reshare(key.KeyID, 4, newParties) - require.NoError(t, err) - - // Verify public key unchanged - require.True(t, bytes.Equal(newKey.PublicKey, originalPubKey)) - - // Verify new configuration - require.Equal(t, 4, newKey.Threshold) - require.Equal(t, 7, newKey.TotalParties) - require.Equal(t, key.Generation+1, newKey.Generation) - - // Verify signing works with new parties - message := sha256.Sum256([]byte("post-reshare test")) - sig, err := tchain.Sign(newKey.KeyID, message[:], newParties[:4]) - require.NoError(t, err) - require.True(t, ecdsa.Verify(originalPubKey, message[:], sig)) -} - -func TestFROSTTaproot(t *testing.T) { - // Setup 3-of-5 FROST key for Bitcoin Taproot - key := setupTestKey(t, 5, 3, FROST_SCHNORR, SECP256K1) - message := sha256.Sum256([]byte("bitcoin transaction")) - - // Sign with FROST - sig, err := tchain.SignTaproot(key.KeyID, message[:], key.PartyIDs[:3]) - require.NoError(t, err) - - // Verify BIP-340 signature format - require.Len(t, sig.R, 32) // x-only - require.Len(t, sig.S, 32) - - // Verify with Bitcoin Taproot verification - valid := taproot.Verify(key.PublicKey.X(), message[:], sig) - require.True(t, valid) -} - -func TestByzantineSignerDetection(t *testing.T) { - key := setupTestKey(t, 5, 3) - - // Simulate malicious signer submitting invalid share - session := startSignSession(t, key.KeyID) - - // Honest signers submit valid commitments - for _, pid := range key.PartyIDs[:2] { - submitValidCommitment(t, session, pid) - } - - // Malicious signer submits mismatched commitment/share - maliciousPID := key.PartyIDs[2] - commitment := submitValidCommitment(t, session, maliciousPID) - - // Submit share that doesn't match commitment - invalidShare := []byte("invalid share data") - err := submitShare(t, session, maliciousPID, invalidShare) - require.Error(t, err) - require.Contains(t, err.Error(), "commitment mismatch") - - // Verify slashing event created - events := getSlashingEvents(t, maliciousPID) - require.Len(t, events, 1) - require.Equal(t, "commitment_mismatch", events[0].Reason) -} - -func TestProactiveRefresh(t *testing.T) { - key := setupTestKey(t, 5, 3) - originalPubKey := key.PublicKey - originalGeneration := key.Generation - - // Trigger refresh - refreshedKey, err := tchain.RefreshShares(key.KeyID) - require.NoError(t, err) - - // Public key unchanged - require.True(t, bytes.Equal(refreshedKey.PublicKey, originalPubKey)) - - // Generation incremented - require.Equal(t, originalGeneration+1, refreshedKey.Generation) - - // Old shares should no longer work (in real system) - // New shares should work - message := sha256.Sum256([]byte("post-refresh test")) - sig, err := tchain.Sign(key.KeyID, message[:], key.PartyIDs[:3]) - require.NoError(t, err) - require.True(t, ecdsa.Verify(originalPubKey, message[:], sig)) -} -``` - -### Integration Tests - -```go -func TestEndToEndBridgeSignature(t *testing.T) { - // 1.

-### Network Security - -1. **Authenticated Channels**: All signer communication MUST use TLS with mutual authentication -2. **Message Integrity**: All protocol messages MUST include authenticated signatures -3. **Replay Protection**: Session IDs and nonces MUST be verified -4. **DoS Mitigation**: Rate limiting on sign requests, session limits per key - -### Operational Security - -1. **Monitoring**: Real-time alerting for failed sessions, slashing events -2. **Incident Response**: Procedures for key rotation on compromise -3. **Audit Logging**: Complete transcript of all protocol messages -4. **Access Review**: Regular review of key owners and delegatees -

It covers the production implementation details, RPC API specification, security hardening measures, and integration patterns for developers building on Lux Network's threshold FHE infrastructure. - -## Motivation - -While prior LPs (LP-0203, LP-5330) define the high-level architecture for threshold FHE on the T-Chain, developers require a comprehensive, practical guide to securely and efficiently implement applications using this powerful technology. This LP serves as the canonical implementation guide, providing detailed specifications for the RPC API, security best practices, and ready-to-use integration patterns. By consolidating this information, we lower the barrier to entry for developers, reduce the risk of implementation errors, and accelerate the adoption of privacy-preserving applications on the Lux Network. - -## Implementation Overview - -The T-Chain FHE module provides threshold decryption capabilities where no single party holds the complete secret key. The implementation uses: - -- **CKKS Scheme**: For approximate arithmetic on encrypted data -- **Lattice-based Multiparty Protocol**: From `luxfi/lattice/multiparty` for threshold operations -- **67-of-100 Threshold**: Default committee configuration -- **Warp Messaging**: For cross-chain FHE requests and results - -### Architecture - -``` -┌─────────────────────────────────────────────────────────────────────────┐ -│ T-Chain FHE Architecture │ -├─────────────────────────────────────────────────────────────────────────┤ -│ │ -│ ┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐ │ -│ │ RPC Layer │ │ Handler Layer │ │ Relayer Layer │ │ -│ │ (TFHEService) │◄───►│ (WarpHandler) │◄───►│ (Relayer) │ │ -│ └────────┬────────┘ └────────┬────────┘ └────────┬────────┘ │ -│ │ │ │ │ -│ ▼ ▼ ▼ │ -│ ┌─────────────────────────────────────────────────────────────────┐ │ -│ │ Integration Layer │ │ -│ │ (ThresholdFHEIntegration) │ │ -│ │ ┌──────────────┐ ┌──────────────┐ ┌──────────────┐ │ │ -│ │ │ Sessions │ │ Shares │ │ Results │ │ │ -│ │ │ (map) │ │ (collect) │ │ (combine) │ │ │ -│ │ └──────────────┘ └──────────────┘ └──────────────┘ │ │ -│ └─────────────────────────────────────────────────────────────────┘ │ -│ │ │ -│ ▼ │ -│ ┌─────────────────────────────────────────────────────────────────┐ │ -│ │ Lifecycle Layer │ │ -│ │ (LifecycleManager) │ │ -│ │ ┌──────────────┐ ┌──────────────┐ ┌──────────────┐ │ │ -│ │ │ DKG │ │ Epoch │ │ Key │ │ │ -│ │ │ Ceremonies │ │ Transitions │ │ Rotation │ │ │ -│ │ └──────────────┘ └──────────────┘ └──────────────┘ │ │ -│ └─────────────────────────────────────────────────────────────────┘ │ -│ │ │ -│ ▼ │ -│ ┌─────────────────────────────────────────────────────────────────┐ │ -│ │ Registry Layer │ │ -│ │ (Registry) │ │ -│ │ ┌──────────────┐ ┌──────────────┐ ┌──────────────┐ │ │ -│ │ │ Ciphertexts │ │ Permits │ │ Committees │ │ │ -│ │ │ (handles) │ │ (access) │ │ (epochs) │ │ │ -│ │ └──────────────┘ └──────────────┘ └──────────────┘ │ │ -│ └─────────────────────────────────────────────────────────────────┘ │ -│ │ -└─────────────────────────────────────────────────────────────────────────┘ -``` - -## Core Components - -### 1.

The protocol leverages Linear Secret Sharing (LSS) with Feldman Verifiable Secret Sharing (VSS) to transition signing authority between generations of validators while preserving the same public key. This eliminates the need for bridge contract updates, asset migrations, or service interruptions when validator sets change. - -The protocol introduces six new transaction types (ReshareInitTx, ReshareCommitTx, ReshareShareTx, ReshareVerifyTx, ReshareActivateTx, ReshareRollbackTx) for orchestrating resharing operations on-chain, an **opt-in signer set model** where first 100 validators join via `lux-cli` without resharing, and a Generation Management system for version tracking and atomic rollback. Resharing is triggered ONLY when a signer slot is replaced (not on validator join). The design achieves zero-downtime rotation, proactive security against mobile adversaries, and maintains t-security throughout all protocol phases. - -## Implementation Status - -| Component | Repository | Path | Status | -|-----------|------------|------|--------| -| BridgeVM (B-Chain) | [luxfi/node](https://github.com/luxfi/node) | [`vms/bridgevm/`](https://github.com/luxfi/node/tree/main/vms/bridgevm) | ✅ Implemented | -| ThresholdVM (T-Chain) | [luxfi/node](https://github.com/luxfi/node) | [`vms/thresholdvm/`](https://github.com/luxfi/node/tree/main/vms/thresholdvm) | ✅ Implemented | -| Threshold Crypto | [luxfi/threshold](https://github.com/luxfi/threshold) | [`pkg/`](https://github.com/luxfi/threshold/tree/main/pkg) | ✅ Implemented | -| Bridge App Client | [luxfi/bridge](https://github.com/luxfi/bridge) | [`app/bridge/src/lib/BridgeRPCClient.ts`](https://github.com/luxfi/bridge/tree/main/app/bridge/src/lib/BridgeRPCClient.ts) | ✅ Implemented | -| CLI Integration | [luxfi/cli](https://github.com/luxfi/cli) | `cmd/bridge/` | 🚧 In Progress | - -**Key Source Files:** -- [BridgeVM RPC handlers](https://github.com/luxfi/node/blob/main/vms/bridgevm/rpc.go) - `bridge_registerValidator`, `bridge_getSignerSetInfo`, `bridge_replaceSigner` -- [BridgeVM core logic](https://github.com/luxfi/node/blob/main/vms/bridgevm/vm.go) - `RegisterValidator()`, `RemoveSigner()`, signer set management -- [Threshold MPC protocol]() - CGGMP21 threshold ECDSA implementation - -## Conformance - -The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC 2119] [RFC 8174] when, and only when, they appear in all capitals, as shown here. - -Implementations claiming conformance to this specification: - -1. **MUST** implement all six reshare transaction types (ReshareInitTx, ReshareCommitTx, ReshareShareTx, ReshareVerifyTx, ReshareActivateTx, ReshareRollbackTx) -2. **MUST** preserve the public key across all generation transitions -3. **MUST** verify Feldman VSS commitments for all received shares -4. **MUST** support atomic rollback to previous generation on failure -5. **MUST** invalidate old shares after successful generation activation -6. **MUST** implement opt-in signer registration (first 100 validators, no reshare on join) -7. **MUST** trigger resharing ONLY on signer slot replacement (not on validator join) -8. **SHOULD** support manual reshare triggers via `lux-cli` -9. **MAY** implement custom threshold computation rules - -## Activation - -| Parameter | Value | -|--------------------|--------------------------------------| -| Flag string | `lp333-dynamic-signer-rotation` | -| Default in code | **false** until block X | -| Deployment branch | `v0.0.0-lp333` | -| Roll-out criteria | 67% validator adoption | -| Back-off plan | Generation rollback to previous set | - -## Motivation - -### The Validator Rotation Problem - -Proof-of-Stake networks experience continuous validator churn as nodes join and leave the active set.

Any change requires full re-keying, exposing the master secret during migration. - -2. **Bridge Contract Updates**: Changing the signing key requires updating all dependent contracts on external chains (Ethereum, Bitcoin, etc.), incurring gas costs and coordination overhead. - -3. **Service Interruption**: Re-keying requires temporary suspension of signing operations, creating downtime for cross-chain bridges and custody services. - -4. **Security Window**: During key reconstruction or migration, the master secret is briefly exposed, creating an attack window for adversaries. - -### LSS Solution: Live Resharing - -LSS (Linear Secret Sharing) with dynamic resharing solves these problems: - -```markdown -Generation 0: Parties A, B, C (2-of-3) - | - | ReshareKey(newParties=[A, B, D, E], threshold=3) - v -Generation 1: Parties A, B, D, E (3-of-4) <- Same public key! - | - | ReshareKey(newParties=[B, D, E, F, G], threshold=3) - v -Generation 2: B, D, E, F, G (3-of-5) <- Same public key! -``` - -**Key Properties:** -- Public key never changes (bridge contracts remain valid) -- Old shares become invalidated (departed validators cannot sign) -- Master secret is never reconstructed (zero exposure window) -- Atomic rollback if reshare fails (generation management) - -### Why Dynamic Rotation is Essential - -1. **Operational Continuity**: Validators join/leave without service interruption -2. **Proactive Security**: Regular resharing defeats mobile adversaries accumulating shares -3. **Regulatory Compliance**: Key rotation requirements without asset migration -4. **Economic Efficiency**: Zero gas costs on external chains for signer changes -5. **Decentralization**: Lower barrier to validator rotation encourages participation - -## Specification - -### 1.

The advantage of A in distinguishing the secret s from a uniformly random element r in Z_q is negligible in the security parameter lambda. - -```solidity -Adv_A^{secrecy}(lambda) = |Pr[A(View_S) = s] - Pr[A(View_S) = r]| <= negl(lambda) -``` - -*Proof:* -1. The view of coalition S consists of: - - Their shares: {f(i) : i in S} - - Feldman commitments: {C_j = a_j * G : j in [0, t-1]} - -2. Since |S| < t, by information-theoretic security of Shamir's scheme, the shares {f(i) : i in S} can be produced for ANY value s' in Z_q by choosing appropriate coefficients. - -3. The commitments {C_j} reveal only g^{a_j}, not a_j (by DL hardness). - -4. Thus View_S is statistically independent of s. QED. - -**Theorem 2 (Share Verification Soundness):** -Let A be a PPT adversary. The probability that A produces an invalid share s_i' != f(i) that passes Feldman verification is negligible. - -```solidity -Pr[VerifyShare(s_i', i, {C_j}) = true AND s_i' != f(i)] <= negl(lambda) -``` - -*Proof:* -1. Verification passes iff s_i' * G = sum_{j=0}^{t-1} (i^j * C_j) - -2. Since C_j = a_j * G, the RHS equals (sum_{j=0}^{t-1} a_j * i^j) * G = f(i) * G - -3. For s_i' != f(i) to pass: s_i' * G = f(i) * G - -4. This requires solving the discrete logarithm: given f(i) * G, find s_i' != f(i) such that s_i' * G = f(i) * G - -5. By the binding property of the DL problem in G, this occurs with probability at most 1/q (negligible). QED. - -**Theorem 3 (Resharing Security):** -Let (t_old, n_old) be the old configuration and (t_new, n_new) be the new configuration. Assuming at least t_old honest parties participate in resharing: - -(a) **Correctness:** New shares {a'_j} satisfy f'(0) = f(0) = s (same secret) -(b) **Forward Secrecy:** Old shares are information-theoretically independent of new shares -(c) **Threshold Security:** Any t_new new shares can reconstruct s; fewer cannot - -*Proof of (a):* -1. Each old party i contributes: lambda_i * a_i where lambda_i is the Lagrange coefficient at 0 - -2. Sum of contributions: sum_{i in S_old} (lambda_i * a_i) = f(0) = s (by Lagrange interpolation) - -3. New polynomial f' is constructed such that f'(0) = s and f'(j) = a'_j for new party j - -4. Therefore f'(0) = f(0) = s. QED. - -*Proof of (b):* -1. New shares are derived from fresh randomness (blinding polynomials w, q) - -2. The joint distribution (old_shares, new_shares) factors as: - P(old, new) = P(old) * P(new | f(0)) - -3. Conditioned only on the secret s = f(0), old and new shares are independent. QED. - -*Proof of (c):* -1. New shares lie on a degree-(t_new - 1) polynomial f' - -2. t_new points uniquely determine f', hence f'(0) = s - -3.

On-Chain Transaction Types vs Off-Chain Protocol - -**Choice:** Hybrid approach with on-chain coordination and off-chain share distribution. - -**Rationale:** -- On-chain transactions provide auditability and finality -- Off-chain share distribution preserves confidentiality -- Commitments and verifications are public; actual shares are encrypted -- Enables governance oversight without compromising security - -#### 2. Generation-Based Versioning - -**Choice:** Monotonically increasing generation numbers with explicit activation. - -**Rationale:** -- Clear ordering of key configurations -- Atomic transitions (no ambiguous states) -- Simple rollback semantics (revert to generation N) -- Compatible with blockchain's linear history - -#### 3. Validator Set as Default Party Source - -**Choice:** Automatic integration with platform validators. - -**Rationale:** -- Natural alignment with network security model -- Validators already have stake at risk (economic security) -- Automatic rotation with validator set changes -- No separate signer registration required - -#### 4. Feldman VSS over Pedersen VSS - -**Choice:** Feldman VSS for commitment scheme. - -**Rationale:** -- Simpler implementation (no additional blinding) -- Sufficient for our security model (discrete log hardness) -- Lower computational overhead -- Well-established security proofs - -### Trade-off: Coordinator Dependency - -**Chosen Trade-off:** Coordinator-assisted resharing. - -**Why:** A coordinator simplifies liveness guarantees and state synchronization. The coordinator is trusted for liveness only, not secrecy - it never sees plaintext shares. - -**Mitigation:** Coordinator can be replicated or rotated. If coordinator fails, reshare times out and rolls back to previous generation. - -## Backwards Compatibility - -### Existing Systems - -This LP is fully backwards compatible: - -1. **Existing Keys**: Can be migrated to Generation 0 of the new system -2. **Static Threshold Systems**: Continue operating unchanged -3. **Current Signing Protocol**: No changes to sign/verify interface -4. **External Contracts**: Public keys remain stable; no contract updates needed - -### Migration from Static Signers - -Systems using static (non-rotatable) threshold keys can migrate to dynamic signer rotation without key regeneration or service interruption. This section specifies the migration protocol. - -#### Migration Phases - -**Phase 1: Inventory and Assessment** -```solidity -1. Enumerate all static threshold keys in the system -2. For each key, record: - - Public key (to be preserved) - - Current threshold (t) - - Current party set (P) - - Share commitments (if Feldman VSS was used) - - Key usage (bridge, custody, governance, etc.) -3. Verify all parties hold valid shares -4. Determine migration priority based on key criticality -``` - -**Phase 2: Generation 0 Bootstrap** -```solidity -1. Create Generation 0 state from existing static configuration -2. Parties retain their existing shares (no reshare required) -3. Register key with GenerationManager -4. Enable ValidatorWatcher monitoring (if applicable) -5. Verify signing still works with Generation 0 configuration -``` - -**Phase 3: First Reshare (Optional Validation)** -```solidity -1. Trigger a reshare to same party set with same threshold -2. This validates the reshare protocol works correctly -3. Verify: - - Public key unchanged - - All new shares pass verification - - Signing works with Generation 1 -4. Rollback to Generation 0 if any issues -``` - -**Phase 4: Production Enable** -```solidity -1. Enable automatic validator change triggers -2. Configure proactive refresh schedule -3.

Each `ManagedKey` operates independently with its own threshold (t), total party count (n), and signer set, allowing distinct security configurations per bridged asset. High-value assets (e.g., BTC, large USDC pools) use higher thresholds (4-of-7 or 5-of-9) for stronger security, while lower-value or high-frequency assets use reduced thresholds (2-of-3) for faster signing latency. This design isolates key compromise risks, enables flexible governance per asset class, and optimizes performance based on asset risk profiles. The specification covers key naming conventions, threshold selection guidelines, key lifecycle management, signer assignment strategies, cross-key coordination, monitoring, and a complete RPC API for key management operations. - -## Motivation - -### Problem Statement - -Current bridge architectures typically employ a single threshold signature configuration for all assets. This one-size-fits-all approach creates several problems: - -1. **Suboptimal Security-Performance Trade-off**: A single threshold must balance security needs of high-value assets against latency requirements of frequent low-value transfers. A 5-of-9 threshold secure enough for BTC custody imposes unnecessary 800ms latency on $50 USDC transfers. - -2. **Uniform Compromise Impact**: If a universal key is compromised, all bridged assets are at risk simultaneously. There is no compartmentalization of custody risk. - -3. **Inflexible Governance**: Different asset classes may have different stakeholders, compliance requirements, or operational needs. A uniform signer set cannot accommodate these differences. - -4. **Inefficient Resource Allocation**: High-capability signers are required for all operations, even trivial transfers where simpler hardware would suffice. - -### Solution - -Per-asset threshold key management addresses these problems by treating each `ManagedKey` as an independent cryptographic entity: - -```go -// From thresholdvm/vm.go -type ManagedKey struct { - KeyID string // "eth-usdc", "lux-btc", etc. - Threshold int // t value for THIS key - TotalParties int // n value for THIS key - PartyIDs []party.ID // Signers for THIS key - Algorithm MPCAlgo // CGG21, MuSig2, FROST, Ringtail - CreatedAt uint64 // Block height - LastRotation uint64 // Last key refresh height - Metadata KeyMetadata // Extended attributes -} -``` - -Example configurations demonstrating flexibility: - -| KeyID | Threshold | Parties | Use Case | -|-------|-----------|---------|----------| -| `lux-usdc` | 2-of-3 | 3 | Fast, frequent small transfers | -| `eth-btc` | 4-of-7 | 7 | High-value BTC custody | -| `zoo-nft` | 3-of-5 | 5 | Balanced NFT bridge | -| `eth-usdc-large` | 5-of-9 | 9 | Large USDC (>$100K) transfers | -| `btc-native` | 5-of-9 | 9 | Native BTC via Taproot MuSig2 | - -### Benefits - -1. **Risk-Based Security**: Higher-value assets receive proportionally stronger protection through increased thresholds and larger signer committees. - -2. **Performance Optimization**: Low-value, high-frequency transfers complete faster with reduced thresholds, improving user experience without compromising security for the value at stake. - -3. **Flexible Governance**: Different asset classes can have distinct governance models, compliance structures, and operational procedures appropriate to their specific requirements. - -4. **Isolated Compromise**: Compromising one key's signer set does not affect other keys. An attacker who compromises signers for `eth-usdc` cannot sign for `btc-native` unless those signers overlap and meet the threshold for both. - -5. **Regulatory Compliance**: Certain jurisdictions or asset types may require specific custody arrangements. Per-asset keys enable compliance with diverse regulatory frameworks. - -6. **Operational Efficiency**: Signer hardware and availability requirements can be tailored per asset, reducing infrastructure costs for lower-risk assets. - -## Specification - -### 1. Key Naming Convention - -Keys follow a hierarchical naming scheme that encodes source chain, asset, and optional variant: - -``` -{source_chain}-{asset_symbol}[-{variant}] -``` - -This naming convention provides: -- **Uniqueness**: Each key has a globally unique identifier -- **Discoverability**: Keys can be enumerated by chain or asset -- **Clarity**: The purpose and scope of each key is immediately apparent -- **Extensibility**: New chains and assets can be added without conflicts - -#### 1.1 Source Chain Identifiers - -| Chain | Identifier | Chain ID | Notes | -|-------|------------|----------|-------| -| Ethereum | `eth` | 1 | Mainnet only | -| Bitcoin | `btc` | N/A | Mainnet, Taproot addresses | -| Lux | `lux` | 96369 | All Lux chains (C-Chain) | -| ZOO | `zoo` | 200200 | ZOO network mainnet | -| SPC | `spc` | 36911 | SparklePonya Club mainnet | -| Hanzo | `hanzo` | 36963 | Hanzo AI network | -| Arbitrum | `arb` | 42161 | Arbitrum One | -| Base | `base` | 8453 | Base L2 | -| Optimism | `op` | 10 | Optimism mainnet | -| Polygon | `poly` | 137 | Polygon PoS | -| XRP Ledger | `xrpl` | N/A | XRPL mainnet | -| Solana | `sol` | N/A | Solana mainnet | -| BNB Chain | `bsc` | 56 | BNB Smart Chain | -| Avalanche | `avax` | 43114 | Avalanche C-Chain | - -#### 1.2 Asset Symbol Rules - -- Use lowercase ticker symbols: `btc`, `eth`, `usdc`, `usdt` -- For native tokens, use chain name: `eth-eth`, `btc-native`, `lux-lux` -- For wrapped tokens, prefix with `w`: `eth-wbtc`, `arb-weth` -- For NFT collections, use collection identifier: `eth-bayc`, `eth-cryptopunks` - -#### 1.3 Variant Suffixes - -Optional suffixes indicate specialized configurations.

Compromise of shares for one key reveals nothing about other keys. - -2. **Signer Set Separation**: Even when signers overlap between keys, the threshold requirement is evaluated independently. An attacker controlling t-1 signers for Key A and t-1 signers for Key B cannot combine knowledge to forge signatures for either key. - -3. **Value Compartmentalization**: Maximum custody value per key can be enforced, limiting exposure from any single key compromise. - -### Compromise Scenarios - -| Scenario | Impact | Mitigation | -|----------|--------|------------| -| Single signer compromised | None (t-1 shares insufficient) | Detect via anomaly, rotate | -| t-1 signers compromised | None (threshold not met) | High alert, emergency rotation | -| t signers compromised | Single key funds at risk | Other keys unaffected; value limits cap loss | -| Algorithm break (ECDSA) | Keys using that algorithm at risk | Migrate to PQ algorithms; dual-sig mode | -| Key metadata leaked | Operational intelligence exposed | Metadata is mostly public; shares remain secure | - -### Attack Surface Minimization - -```go -// Access control for key operations -type Permission uint8 - -const ( - PermNone Permission = iota - PermRead // View key metadata - PermSign // Request signatures - PermOperate // Manage signers - PermGovernance // Create/revoke keys -) - -type ACL struct { - KeyID string - Permissions map[ids.ShortID]Permission -} - -func (vm *VM) CheckPermission(caller ids.ShortID, keyID string, required Permission) error { - acl := vm.state.GetACL(keyID) - if acl.Permissions[caller] < required { - return fmt.Errorf("insufficient permission: have %v, need %v", - acl.Permissions[caller], required) - } - return nil -} -``` - -### Quantum Security - -Keys may be configured for hybrid classical/quantum security: - -```go -type QuantumConfig struct { - Enabled bool // Dual-signature mode - ClassicalAlgo MPCAlgo // CGG21, MuSig2, FROST - QuantumAlgo MPCAlgo // Ringtail (lattice-based) - ClassicalThresh uint8 - QuantumThresh uint8 -} - -// Dual signature verification -func VerifyDualSignature(msg []byte, classical, quantum []byte, config QuantumConfig) error { - if err := VerifyClassical(msg, classical, config.ClassicalAlgo); err != nil { - return fmt.Errorf("classical signature invalid: %w", err) - } - if config.Enabled { - if err := VerifyQuantum(msg, quantum, config.QuantumAlgo); err != nil { - return fmt.Errorf("quantum signature invalid: %w", err) - } - } - return nil -} -``` - -## Backwards Compatibility - -This LP is additive to existing T-Chain and T-Chain functionality: - -1. **Existing Keys**: Keys created before this specification continue to function. They are implicitly assigned `KeyID` based on their asset and default metadata. - -2. **Legacy RPC**: Existing RPC methods (`mchain.swapSig.*`) remain operational. New methods are additive. - -3. **Transaction Formats**: New transaction types (`KeyCreateTx`, `KeyRotateTx`, etc.) use unused type IDs. Existing transaction processing is unchanged. - -4. **Signer Software**: Existing `mpckeyd` instances can be upgraded incrementally. The protocol negotiates capabilities during DKG. - -## Rationale - -### Design Decisions - -1. **Per-Asset Isolation**: Each managed key operates independently with its own threshold (t), total party count (n), and signer set. This provides cryptographic isolation where compromise of one key does not affect others, enabling risk-appropriate security configurations per asset. - -2. **Value-Based Tiering**: Threshold and party count scale with asset value to balance security requirements against operational efficiency. High-value assets receive proportionally stronger protection (higher thresholds, larger committees) while low-value assets optimize for speed. - -3. **Hierarchical Key Naming**: The `{chain}-{asset}[-{variant}]` naming convention provides uniqueness, discoverability, and extensibility. New chains and assets can be added without conflicts while maintaining clear operational semantics. - -4. **Geographic Diversity**: Signer distribution across multiple jurisdictions ensures resilience against regional failures, regulatory actions, and coordinated attacks. Higher-value tiers require more geographic diversity. - -5. **Algorithm Flexibility**: Supporting multiple MPC algorithms (CGG21, MuSig2, FROST, Ringtail) enables native compatibility with different blockchain curves and provides a quantum-safe migration path. - -6. **Proactive Key Refresh**: Time-based share regeneration without changing public keys provides forward security while maintaining operational continuity. Refresh intervals scale inversely with asset value. - -## Test Cases - -### Key Creation Tests - -```go -func TestKeyCreation_ValidConfig(t *testing.T) { - vm := setupTestVM() - - tx := &KeyCreateTx{ -

Long-term secrets encrypted today can be harvested and decrypted later ("harvest now, decrypt later" attacks). - -2. **Centralized KMS Dependencies**: dApps requiring encryption typically rely on centralized cloud KMS providers (AWS KMS, Azure Key Vault), introducing single points of failure and trust assumptions. - -3. **No Native Secret Management**: Blockchain state is public by design. Applications requiring encrypted state must implement custom off-chain solutions without standard primitives. - -4. **Bridge Message Security**: Cross-chain bridges transmit sensitive payloads that should be encrypted in transit and at rest, but lack a standard encryption infrastructure. - -5. **Credential Storage**: Decentralized identity systems (DIDs, Verifiable Credentials) need secure storage for private credentials without relying on centralized vaults. - -### Solution: Dedicated Key Management Chain - -K-Chain addresses these challenges by providing a specialized blockchain for cryptographic operations: - -1. **Post-Quantum Security**: ML-KEM (FIPS 203) provides lattice-based key encapsulation resistant to both classical and quantum attacks -2. **Decentralized HSM**: On-chain key management with threshold access control eliminates single points of failure -3. **Native Encryption Primitives**: Standard API for key generation, encapsulation, and data encryption -4. **T-Chain Integration**: Threshold decryption ensures no single party can access secrets -5. **Hybrid Security**: Combined ML-KEM + ECDH provides defense-in-depth during quantum transition - -### Use Cases - -- **Encrypted Bridge Messages**: End-to-end encryption for cross-chain payloads via B-Chain -- **Private Smart Contract State**: Encrypted state variables for DeFi, gaming, and enterprise contracts -- **Secure Credential Storage**: DID/Verifiable Credential encryption with selective disclosure -- **Enterprise Key Management**: HSM-equivalent functionality for institutional custody -- **Post-Quantum Security**: Future-proof encryption for long-term secrets (medical records, legal documents) -- **IPFS Encrypted Storage**: Encrypted file storage with decentralized key management - -## Specification - -### Chain Architecture - -K-Chain is a specialized Lux chain running the KeyManagementVM: - -```solidity -+-------------------------------------------------------------------------+ -| K-Chain Architecture | -+-------------------------------------------------------------------------+ -| | -| +-----------------+ +------------------+ +------------------+ | -| | ML-KEM | | Secret | | Access | | -| | Engine | | Store | | Control | | -| | | | | | | | -| | - KeyGen | | - Encrypted | | - Policies | | -| | - Encapsulate | | Storage | | - AuthZ | | -| | - Decapsulate | | - Versioning | | - Audit | | -| | - Hybrid Mode | | - Rotation | | - Time-locks | | -| +-----------------+ +------------------+ +------------------+ | -| | | | | -| +--------------------+--------------------+ | -| | | -| +----------v-----------+ | -| | T-Chain Bridge | | -| | | | -| | - Threshold Decrypt | | -| | - LSS Integration | | -| | - Multi-Party Auth | | -| +----------------------+ | -| | -+-------------------------------------------------------------------------+ -``` - -### Core Components - -#### 1.

- -1. **NIST Standardization**: FIPS 203 is the official US government standard for post-quantum KEM -2. **Mature Cryptanalysis**: Based on CRYSTALS-Kyber, extensively analyzed since 2017 -3. **Performance**: Efficient key generation, encapsulation, and decapsulation -4. **Security Margin**: Multiple parameter sets for different security levels - -### Why Hybrid Mode? - -During the transition to post-quantum cryptography: -1. **Defense in Depth**: If ML-KEM has undiscovered weaknesses, ECDH provides backup -2. **Regulatory Compliance**: Some standards still require classical cryptography -3. **Interoperability**: Enables gradual migration from classical systems - -### Why T-Chain Integration?

-### TypeScript SDK - -The library is exposed via TypeScript SDK at `@luxfi/threshold` (see LP-7341). - -## Rationale - -### Multi-Protocol Support - -Supporting multiple threshold protocols addresses different use cases: - -1. **LSS**: Best for general-purpose use with fast keygen -2. **CMP (CGGMP21)**: UC-secure with identifiable abort for high-security applications -3. **FROST**: Optimal for Schnorr-based chains (Bitcoin Taproot) -4. **Doerner**: Efficient 2-party ECDSA for simpler deployments -5. **Ringtail**: Post-quantum threshold signatures for future-proofing - -### Modular Architecture - -The modular design provides: - -1. **Isolation**: Protocol bugs don't affect other implementations -2. **Testing**: Each protocol tested independently -3. **Upgrades**: New protocols can be added without changing existing code -4. **Selection**: Applications choose optimal protocol for their needs - -### Worker Pool Design - -Using a shared worker pool enables: - -1. **Resource Control**: Limit concurrent cryptographic operations -2. **Parallelism**: Maximize CPU utilization for expensive operations -3. **Fairness**: Prevent single operation from monopolizing resources - -## Backwards Compatibility - -### API Stability - -The library maintains backwards compatibility through: - -- Stable `protocol.StartFunc` interface -- Versioned config structures -- Additive-only changes to public APIs - -### Protocol Version Support - -- All protocols support version negotiation -- Older key shares work with newer library versions -- Explicit migration paths when breaking changes required - -### Integration Compatibility - -Works seamlessly with: - -- ThresholdVM (T-Chain) - primary integration -- BridgeVM (B-Chain) - cross-chain signing -- External applications via standard interfaces - -## Test Cases - -### Protocol Tests -

-## Abstract - -This LP documents `github.com/luxfi/mpc`, a high-performance, open-source Multi-Party Computation (MPC) engine for securely generating and managing cryptographic wallets across distributed nodes. The system enables threshold signatures without ever exposing the full private key, supporting both classical (ECDSA, EdDSA) and post-quantum signature schemes. - -## Motivation - -Traditional custody solutions have critical weaknesses: - -1. **Single Point of Failure**: One compromised key loses all assets -2. **Key Management Complexity**: Secure storage and backup of private keys -3. **Trust Concentration**: Custodians have full control over funds -4. **Quantum Vulnerability**: ECDSA keys will be vulnerable to quantum attacks - -Lux MPC solves these by: - -- Distributing key shares across multiple nodes (no single party has full key) -- Requiring threshold cooperation for signing (e.g., 2-of-3) -- Supporting key refresh without changing public key -- Integrating with post-quantum schemes via Ringtail -

This tier provides maximum security for the most sensitive workloads. + +2. **Tier 2 (Confidential VM)**: AMD, Intel, and Arm all offer CPU-level CC. Combined with GPU passthrough, this provides strong isolation without requiring specialized GPU hardware. + +3. **Tier 3 (Device TEE)**: Mobile and edge devices have integrated TEEs with AI accelerators. This tier enables the vast ecosystem of edge AI devices. + +### Why Not Include DGX Spark (GB10)? + +NVIDIA DGX Spark (GB10) uses the Grace SoC without NVTrust support for the AI components. It's classified as Tier 4 (Standard) because: +- No hardware CC for GPU memory +- Software attestation only +- Suitable for non-sensitive workloads + +### Trust Score Design + +The trust score calculation balances: +- **Hardware (40%)**: Incentivizes CC hardware adoption +- **Attestation (30%)**: Rewards fresh attestations +- **Reputation (20%)**: Values historical reliability +- **Uptime (10%)**: Ensures availability + +This weighting ensures that hardware CC tier is the primary differentiator while still rewarding good behavior. + +## Backwards Compatibility + +This LP extends LP-2001 (AIVM) with CC tier awareness: + +- Existing providers default to Tier 4 (Standard) +- Tasks without `minCCTier` field are matched to any tier +- Trust scores are backwards compatible with

-This library depends on `luxcpp/gpu` (LP-5700) for GPU acceleration: - -``` -luxcpp/gpu ← Foundation (Metal/CUDA/CPU) - ▲ - │ NTT, FFT, array ops - │ -luxcpp/lattice ← Uses gpu for NTT acceleration - ▲ - │ CGO bindings - │ -lux/lattice ← Go library with optional GPU - ▲ - │ provides ring operations - │ -lux/fhe ← FHE-specific APIs (LP-5702) -``` - -**Dependency Rule**: `lux/lattice` can run standalone (pure Go) or with GPU acceleration (CGO + luxcpp/lattice). - -## Rationale - -### Why Pure Go with Optional CGO? - -1. **Portability**: Pure Go compiles to WASM for browser-based FHE -2. **Performance**: CGO binding to C++ provides near-native GPU performance -3. **Flexibility**: Developers choose based on deployment environment -4. **Testing**: Pure Go ensures correctness; CGO provides speed - -### Why Full-RNS? - -1. **Arbitrary Precision**: Handle large ciphertext moduli via Chinese Remainder Theorem -2. **Parallelization**: Each RNS component computes independently -3. **No Arbitrary Precision**: Avoids big integer arithmetic -4. **Proven**: Industry standard for modern FHE implementations - -### Why BGV, BFV, and CKKS? - -- **BGV/BFV**: Exact integer arithmetic for voting, PIR, private set intersection -- **CKKS**: Approximate arithmetic for ML inference, statistics, financial modeling -- All three share the RLWE foundation, minimizing code duplication - -## Backwards Compatibility - -New library. No backwards compatibility concerns. - -## Test Cases - -### Ring Tests - -1. NTT forward/inverse roundtrip preserves polynomial -2. Polynomial multiplication matches schoolbook multiplication -3. RNS basis extension is exact -4. Scaling introduces expected precision loss - -### RLWE Tests - -1. Encryption/decryption roundtrip -2. Public key has correct noise distribution -3. Relinearization key enables degree reduction -4. Galois keys enable correct slot rotations - -### Scheme Tests (BGV/CKKS) - -1. Homomorphic addition is correct -2. Homomorphic multiplication is correct -3. Rescaling manages noise correctly -4. Bootstrap refreshes ciphertext - -### Multiparty Tests - -1. DKG produces correct collective public key -2. Threshold decryption with t parties succeeds -3. Threshold decryption with t-1 parties fails -4. Collective bootstrap maintains security - -### GPU Tests - -1. GPU NTT matches pure Go NTT -2. GPU polynomial multiplication is correct -3. Backend detection works on supported platforms -4.

Built on the lattice cryptography foundation (LP-5701), it provides boolean gates, integer arithmetic, and GPU-accelerated programmable bootstrapping for blockchain/EVM integration. - -**Architecture Note**: This library provides single-party FHE primitives only. **Threshold FHE** operations (collective decryption, threshold key generation, key refresh) are implemented in `lux/threshold/protocols/tfhe` (LP-5703), which consumes these primitives. Applications requiring threshold decryption should use `lux/threshold`, not this library directly. - -## Motivation - -FHE enables confidential computation on encrypted data without decryption: - -- **Confidential Smart Contracts**: Execute EVM bytecode on encrypted state -- **Private DeFi**: Trading, lending, auctions without revealing positions -- **Encrypted Databases**: Query encrypted on-chain data -- **Privacy-Preserving ML**: Inference on encrypted inputs - -Key requirements for blockchain integration: - -1. **EVM Types**: Native FheUint160 (addresses), FheUint256 (EVM words) -2. **GPU Acceleration**: 10,000+ concurrent users with batched operations -3. **Deterministic RNG**: Consensus-compatible randomness generation -4. **Primitive Foundation**: Clean APIs that `lux/threshold/protocols/tfhe` builds upon -

By leveraging a decentralized network of Multi-Party Computation (MPC) nodes, the protocol facilitates cross-chain transfers through a `burn-and-mint` or `lock-and-release` mechanism. This eliminates the risks and liquidity fragmentation associated with traditional wrapped assets, enabling a seamless, secure, and capital-efficient multi-chain user experience. The protocol supports EVM, UTXO (Lux-like), and other blockchain architectures, providing a unified solution for interoperability. + +## Motivation + +The current multi-chain landscape is fragmented. Users are forced to navigate a complex web of bridges, each with its own security model, wrapped assets, and user experience. This creates significant friction, exposes users to security risks (e.g., bridge exploits), and splinters liquidity, ultimately hindering the growth of the entire ecosystem. + +The Lux Teleport Protocol addresses these problems by: + +* **Eliminating Wrapped Assets:** Assets move between chains as native assets, maintaining their integrity and value. +* **Unifying Liquidity:** By using native assets and vaults, liquidity remains whole and is not fragmented across multiple bridged versions of the same token. +* **Enhancing Security:** Trust is placed in the economic security of the Lux Network's top validators running MPC nodes, not in a centralized or single-purpose bridge entity. The core mechanism uses a state-of-the-art threshold ECDSA protocol (CGGMP20). +* **Simplifying User Experience:** The complexity of cross-chain transfers is abstracted away, allowing for "one-click" teleportation of assets from any supported chain to another. +* **Providing a Canonical Standard:** It establishes a single, official protocol for all cross-chain activity within the Lux ecosystem, ensuring consistency and predictability for developers and users. + +## Specification + +The Lux Teleport Protocol formalizes the interaction between user wallets, a decentralized network of MPC nodes (referred to as the "b-chain"), and on-chain smart contracts (`Teleporter` and `Vault` contracts). + +**1. Core Components:** + +* **MPC Node Network (B-Chain):** A decentralized network of the top 100 opted-in LUX validators. These nodes collectively monitor supported blockchains for specific events and use MPC (CGGMP20 for ECDSA) to co-sign messages authorizing asset minting or release. +* **Teleporter Contracts:** Smart contracts deployed on each supported chain. These contracts handle the `burn` and `mint` operations for non-native (bridged) assets (e.g., `ERC20B`). +* **Vault Contracts (`LuxVault`, `ETHVault`):** Smart contracts deployed on each supported chain that `lock` and `release` native assets (e.g., LUX, ETH). +* **Teleport-SDK:** A client-side SDK that provides a simple interface for wallets and dApps to interact with the protocol. + +**2. Workflow:** + +The protocol operates via two primary workflows, determined by the nature of the asset being transferred. + +**A) Burn-and-Mint (for Wrapped/Bridged Assets):** + +1. **Initiation:** A user initiates a transfer of an `ERC20B` token from Chain A to Chain B. +2. **Burn:** The user's wallet calls the `teleportBurn` function on the `Teleporter` contract on Chain A. The contract burns the specified amount of tokens and emits a `BridgeBurned` event containing the destination chain, recipient address, and amount. +3. **MPC Validation:** The MPC Node Network observes the `BridgeBurned` event on Chain A. A threshold of nodes validates the transaction. +4. **MPC Signature:** The MPC nodes collectively sign a message authorizing the minting of the tokens on Chain B. +5. **Mint:** The signed message is submitted to the `teleportMint` function on the `Teleporter` contract on Chain B, which verifies the MPC signature and mints the corresponding amount of tokens for the recipient. + +**B) Lock-and-Release (for Native Assets):** + +1. **Initiation:** A user initiates a transfer of a native asset (e.g., ETH) from Chain A to Chain B. +2. **Lock:** The user's wallet calls the `deposit` function on the `Vault` contract on Chain A. The contract locks the assets and emits a `VaultDeposit` event. +3. **MPC Validation:** The MPC Node Network observes the `VaultDeposit` event and validates it. +4. **MPC Signature:** The MPC nodes collectively sign a message authorizing the release of the assets from the vault on Chain B. +5. **Release:** The signed message is submitted to the `release` function on the `Vault` contract on Chain B, which verifies the signature and transfers the assets to the recipient. + +**C) UTXO Chains (e.g., Lux X-Chain):** + +1. **Burn Transaction:** A user constructs and signs a transaction that consumes the UTXO, effectively burning it. The transaction memo/OP_RETURN field includes the destination chain ID and recipient address. +2. **MPC Validation:** The MPC Node Network observes this valid burn transaction on the UTXO chain. +3. **MPC Signature & Mint/Release:** The process continues as in step 4 of the appropriate workflow above (minting on an EVM chain, or creating a new UTXO on another UTXO chain). + +## Rationale + +The design of the Lux Teleport Protocol prioritizes security, decentralization, and user experience. + +* **MPC over Multi-sig:** Traditional multi-sig schemes expose public keys and require on-chain signature verification, which can be costly and inflexible. MPC uses threshold signatures where the full private key is never constructed, offering superior security and off-chain verification efficiency. CGGMP20 is a well-regarded and audited protocol for this purpose. +* **Dual Workflow (Burn/Mint vs. Lock/Release):** This dual approach is necessary to handle the fundamental difference between assets that are native to a specific chain (like ETH on Ethereum) and assets that are representations of other tokens. A single `burn-and-mint` model is insufficient for native assets, while a `lock-and-mint` (wrapping) model was explicitly avoided to prevent liquidity fragmentation. +* **Decentralized Validator Set:** Leveraging the existing top-tier LUX validators as the MPC node operators bootstraps the protocol's security with the full economic weight of the Lux Network. + +## Backwards Compatibility + +This LP is designed to formalize and standardize an existing, operational system. It introduces no backwards incompatibilities. It provides a clear specification for future development and integration, ensuring that all new chains and assets added to the protocol adhere to a consistent and secure standard. + +## Test Cases + +Reference test cases are implemented within the `/bridge` project repository. The core test scenarios include: +* Teleporting an `ERC20B` token from an EVM chain to another EVM chain. +* Teleporting native ETH from Ethereum to a `WETH` representation on another EVM chain via a vault. +* Teleporting a UTXO asset from the X-Chain to an EVM chain. +* Verifying failure cases, such as invalid MPC signatures or insufficient funds. + +## Reference Implementation + +The reference implementation for the Lux Teleport Protocol is the existing Lux Network MPC Bridge located in the `/bridge` directory of the Lux monorepo. +* **Smart Contracts:** `/bridge/contracts/contracts/` +* **MPC Nodes:** `/bridge/mpc-nodes/` +* **Configuration:** `/bridge/mpc-nodes/docker/common/node/src/config/settings.ts` + +## Implementation + +### Local Bridge Components +**Repository Location**: `bridge/` + +### Smart Contracts +- **Teleporter Contracts**: `bridge/contracts/` + - ERC20 burn/mint logic (L2→L2, L1→L2) + - Vault contracts for native assets + - MPC signature verification + +- **Example Contract Addresses**: + - Teleporter: Deployed per chain + - Vault: Native asset (ETH/LUX) locking + - Configuration: Via bridge governance + +### MPC Node Implementation +- **MPC Network**: Top 100 Lux validators +- **Configuration**: + - Threshold ECDSA (CGGMP20 protocol) + - Network coordination: Docker-based setup + - Key management: Hardware Security Module (HSM) support + +### Testing and Deployment +```bash +cd bridge +docker-compose -f compose.local.yml up -d # Local bridge testing +cd test/ +# Run bridge integration tests +``` + +### Cross-Chain Testing +- **Test Cases**: `bridge/test/` + - ERC20 burn-and-mint verification + - Vault lock-and-release scenarios + - UTXO chain interoperability + - MPC signature validation + +### GitHub Repository +- **Main Repository**: https://github.com/luxfi/bridge +- **Contract Interfaces**: Publicly available +- **Documentation**: Bridge protocol specification + +### Integration with Other LPs +- **LP-22**: Warp 2.0 for intra-ecosystem chains +- **LP-23**: NFT teleportation using this protocol +- **LP-19**: Security framework for bridge operations + +## Security Considerations + +The security of the Teleport Protocol rests on several pillars: +1. **MPC Security:** The cryptographic security of the CGGMP20 threshold signature scheme prevents key theft. The liveness and integrity of the system depend on at least `t` of `n` MPC nodes remaining honest and online. +2. **Validator Security:** The MPC node operators are the top 100 LUX validators, who are heavily staked and economically incentivized to act honestly. Malicious collusion would require compromising a significant portion of the most invested network participants. +3. **Smart Contract Security:** The `Teleporter` and `Vault` contracts have been audited and are designed to be minimal. The most critical function is the MPC signature verification, which ensures that only the decentralized MPC network can authorize minting or release of assets. +4. **Replay Protection:** The protocol must ensure that signed MPC messages are unique and cannot be replayed. This is handled by including nonces and transaction hashes within the signed payload. + +## Copyright + +Copyright and related rights waived via [CC0](https://creativecommons.org/publicdomain/zero/1.0/). diff --git a/LPs/lp-6022-warp-messaging-20-native-interchain-transfers.md b/LPs/lp-6022-warp-messaging-20-native-interchain-transfers.md index f4e62ed7..cf68dac6 100644 --- a/LPs/lp-6022-warp-messaging-20-native-interchain-transfers.md +++ b/LPs/lp-6022-warp-messaging-20-native-interchain-transfers.md @@ -4,7 +4,7 @@ title: 'Warp Messaging 2.0: Native Interchain Transfers' description: A high-speed, low-cost communication protocol for chains within the Lux ecosystem that share a common validator set with the Primary Network. author: Gemini (@gemini) discussions-to: https://github.com/luxfi/lps/discussions -status: Implemented +status: Draft type: Standards Track category: Networking created: 2025-07-22 @@ -129,4 +129,3 @@ Additive change; existing interfaces remain valid.

It marries public chain ordering, durable data availability (DA) storage, CRDT-based state synchronization, local SQLite materialization, and optional encrypted compute (via TEE or FHE). The result is a privacy-preserving, scalable "app-chain" model where applications (like ecommerce marketplaces) can operate with high throughput and offline capability, without sacrificing security or decentralization. - -This design eliminates the need for leader-based consensus protocols (no Raft/Paxos clusters) by leveraging CRDTs for conflict-free replication and Lux's chain for finality, all while keeping user data end-to-end encrypted. - -## Motivation - -Traditional blockchain applications face several challenges: -- **Latency**: Users must wait for block confirmation -- **Online requirement**: Apps stop working without network connectivity -- **Privacy**: All data is public on-chain -- **Scalability**: Every operation must pass through consensus - -fheCRDT addresses all of these by enabling: -- Offline-first operation with instant local updates -- End-to-end encryption for all application data -- CRDT-based conflict resolution without central coordination -- Blockchain finality only for ordering, not data storage - -## Specification - -### Architecture Components - -### 1. Public Chain Ordering & Finality - -A Lux L1 chain (or subnet) provides global ordering of events and fast finality for transactions. This ensures that all replicas eventually see a consistent sequence of operations, anchored by the chain's consensus. - -The chain records lightweight receipts (e.g. `DocReceipt` transactions) that reference off-chain data updates, serving as an immutable log of state changes. By using Lux's high-performance consensus, operations confirm quickly and are finalized without forks, establishing a ground truth timeline for state updates. - -### 2. Durable Data Availability (DA) Layer - -Large application data (blobs of encrypted state or CRDT logs) is stored off-chain in the Lux DA layer (LuxDA). When an app needs to persist or share state, it disperses an encrypted blob to DA operators. - -These operators attest that the data is stored and available by signing a **DA Receipt** (an availability certificate). This certificate (or a hash of it) is then posted on-chain in the `DocReceipt` transaction. - -The DA layer guarantees that even if users go offline, their data remains retrievable by others, with fast availability confirmation (~0.5s by committee attestations). LuxDA operates in a trust-minimized mode (upgradable to full Data Availability Sampling in the future), ensuring data is reliably stored without burdening the L1 chain with large files. - -See [LP-6431: Availability Certificates](lp-6431-availability-certificates.md) for detailed DA specification. - -### 3. CRDT-Based State Model - -State is modeled as **CRDTs (Conflict-Free Replicated Data Types)**, which allow concurrent updates and merges without conflicts. Each participant (user, merchant, etc.) keeps a local copy of the state and can update it independently – even offline – and the CRDT guarantees that when all updates propagate, every copy will converge to the same state. - -This removes the need for a single leader or strict global locking on writes. Instead of forcing all transactions through a single sequencer in real-time, operations can be applied in any order and still resolve consistently. - -**Supported CRDT Types:** -- **LWW Register**: Last-Writer-Wins register for simple values -- **MV Register**: Multi-Value register preserving concurrent writes -- **G-Counter**: Grow-only counter -- **PN-Counter**: Positive-negative counter -- **G-Set**: Grow-only set -- **2P-Set**: Two-phase set (add/remove) -- **OR-Set**: Observed-Remove set -- **LWW-Map**: Last-Writer-Wins map -- **RGA List**: Replicated Growable Array for ordered lists - -### 4. Local SQLite Materialization - -Each node or user runs a lightweight SQLite database that materializes the CRDT state into a familiar relational form. The CRDT acts as the convergence engine beneath the hood, while SQLite provides a convenient query layer on top of the replicated state. - -Developers can build on a normal SQL schema and use local queries for app logic, with the assurance that the SQLite DB will stay in sync across devices (thanks to CRDT sync). - -The "source of truth" is collectively maintained by all replicas and notarized by the chain, rather than a central cloud DB. Materializing state locally means reads and writes are low-latency (no network call needed) and apps continue operating smoothly offline. - -### 5. Encrypted Compute (TEE/FHE) - -To preserve privacy, all application data in this model is kept encrypted—both at rest in the DA layer and in motion between clients. Lux's architecture optionally leverages **Trusted Execution Environments (TEE)** and **Fully Homomorphic Encryption (FHE)** to enable computations on encrypted data without revealing it. - -**TEE Options:** -- Intel SGX -- AMD SEV -- NVIDIA Confidential Computing -- ARM TrustZone -- AWS Nitro Enclaves - -**FHE Schemes:** -- BFV (integer arithmetic) -- CKKS (approximate arithmetic) -- TFHE (boolean circuits) - -See [LP-7302: Z-Chain Privacy & Attestation](lp-7302-lux-z-a-chain-privacy-ai-attestation-layer.md) for FHE/TEE integration details. - -## How fheCRDT Works (Step-by-Step) - -### Example: E-commerce Use Case - -#### Step 1: Per-User Encrypted State - -Each user in the marketplace has an encrypted data blob representing their profile, preferences, order history, etc., structured as a CRDT (e.g. a JSON document CRDT). The merchant maintains CRDT documents for product listings, inventory, and so on. - -All data is sharded per user or per logical document – rather than one giant global state – improving privacy and scalability. Encryption keys are held by the data owners (user holds their profile key; merchant holds product data keys). - -#### Step 2: Local Updates, Offline-First - -When a user updates their profile or adds an item to their cart, the update is applied immediately to the user's local SQLite store and CRDT state. The app remains responsive even offline. - -The change is logged as a CRDT operation (e.g. "add this entry to Addresses set") that will later be synced. Multiple offline edits can happen in parallel; the CRDT will merge them without conflict. - -#### Step 3: Data Dispersal to LuxDA - -When the user's device is online (or when a batch of operations is ready), it disperses the encrypted CRDT delta to the Lux DA layer. The data blob is tagged with a namespace and version. - -The LuxDA network stores the blob redundantly. DA operators perform a quick availability committee process: each stores their piece of the erasure-coded data and signs an attestation. The outcome is an **Availability Certificate** confirming the blob is stored. - -#### Step 4: On-Chain Receipt (Ordering the Update) - -The user's client submits a `DocReceipt` transaction to the Lux chain. This transaction includes: -- Reference to the data blob (content hash or DA commitment) -- Availability certificate or its aggregate signature -- Document identifier and version - -When confirmed on-chain, this establishes global order for the update. Finality occurs within seconds. - -#### Step 5: Replication and Merge - -Other parties (merchant server, user's other devices) see the on-chain receipt and fetch the encrypted blob from the DA layer. The availability certificate ensures data integrity. - -Upon retrieval, the recipient's node merges the new data into its local CRDT state. Because CRDT merges are mathematically guaranteed to converge, both parties end up with the same state. Their local SQLite views are updated automatically. - -#### Step 6: Selective Decryption & Compute - -For operations requiring access to encrypted data: -- **Selective sharing**: User encrypts specific fields to merchant's public key -- **TEE processing**: Enclave decrypts internally for processing (e.g., shipping label) -- **FHE computation**: Merchant sends encrypted computation, gets encrypted result - -#### Step 7: Iteration and Continuity - -The cycle repeats for each state update. CRDT logic handles concurrent edits. Blockchain receipts form an ordered log for auditors or new nodes. Periodic snapshots can be anchored on-chain for additional security. - -## New Transaction Types - -### DocReceipt - -A transaction or log entry on a Lux chain that records a document update event. - -```go -type DocReceipt struct { - DocumentID string // Unique document identifier - ContentHash [32]byte // Hash of the encrypted content - Version uint64 // Document version number - Namespace string // Application namespace - DACommitment []byte // DA layer commitment/certificate hash - Timestamp int64 // Unix timestamp - Signature []byte // Creator's signature -} -``` - -### DAReceipt (Availability Certificate) - -A signed certificate from the Data Availability layer confirming blob storage. - -```go -type DAReceipt struct { - BlobID string // Unique blob identifier - ContentHash [32]byte // Hash of the stored content - Size uint64 // Blob size in bytes - ErasureRoot [32]byte // Erasure coding merkle root - Signers [][]byte // Committee member public keys - Signatures [][]byte // Committee signatures - Threshold int // Minimum signatures required - Timestamp int64 // Attestation timestamp - ExpiresAt int64 // Data retention expiry -} -``` - -## Encryption Domains - -fheCRDT supports multiple encryption domains for fine-grained access control: - -| Domain | Description | Access | -|--------|-------------|--------| -| `UserPrivate` | Only the user can decrypt | User's keys only | -| `MerchantPrivate` | Only merchant can decrypt | Merchant's keys only | -| `Shared` | Multi-party access | Threshold decryption | -| `Public` | Unencrypted | No encryption | - -## Benefits Summary - -### No Leaders, No Lag - -- **No elected master node** ordering transactions in real-time -- **Resilient to faults** and network splits -- **Offline operation** with eventual sync -- **Local-first responsiveness** with global trust - -### End-to-End Encryption - -- DA nodes and validators cannot read user or business data -- Only ciphertexts and hashes are visible -- Compliance-sensitive information remains confidential -- Aligns with GDPR and data sovereignty requirements - -### Scalability - -- Heavy lifting happens off-chain -- Chain transactions are minimal (receipts only) -- No block gas limits on data operations -- Horizontal scaling through sharding - -## Rationale - -fheCRDT combines CRDTs with FHE/TEE because no single technology addresses all requirements: CRDTs provide conflict-free offline operation, blockchain provides global ordering and finality, the DA layer provides scalable storage, and FHE/TEE provides privacy. This layered approach allows each component to operate at its optimal scale while maintaining end-to-end encryption guarantees. - -## Backwards Compatibility - -This specification introduces new functionality and does not modify existing protocols.

Warp 1.5 maintains backward compatibility with existing BLS-based signatures while providing a migration path to full quantum resistance. The upgrade includes the Teleport high-level protocol for standardized cross-chain operations (transfers, swaps, attestations, governance, private transfers) and integrates with BridgeVM (B-Chain) and ThresholdVM (T-Chain) for MPC-based signing. + +--- + +## Motivation + +### The Quantum Threat + +Quantum computers threaten all classical cryptography used in blockchains: + +| Algorithm | Quantum Attack | Impact | +|-----------|----------------|--------| +| ECDSA | Shor's algorithm | Private keys recoverable in polynomial time | +| BLS | Shor's algorithm | Signatures forgeable | +| RSA | Shor's algorithm | Completely broken | +| AES-256 | Grover's algorithm | Reduced to 128-bit security (still safe) | + +**Timeline**: NIST estimates cryptographically relevant quantum computers by 2030-2035.

to upgrade immediately? + +**A:** No. Warp 1.5 is backward compatible. BLS signatures continue to work. However, you should plan to migrate to Ringtail before Phase 3 (Q3 2025). + +### Q: How much larger are Ringtail signatures? + +**A:** About 30-50x larger than BLS (~3-5KB vs 96 bytes). This is the tradeoff for quantum safety. For most applications, this is acceptable. + +### Q: Can I use encryption without Ringtail? + +**A:** Yes. The ML-KEM encryption is independent of signature type. You can encrypt payloads with any signature type. + +### Q: What if a validator's key is compromised? + +**A:** Use LP-333's `bridge_replaceSigner` to remove the compromised validator and trigger a reshare. The compromised key cannot sign new messages after removal. + +### Q: Is Ringtail NIST approved? + +**A:** Ringtail is based on LWE, which is NIST-approved (ML-KEM/ML-DSA use similar assumptions). Ringtail specifically provides native threshold support not available in ML-DSA. + +--- + +## Rationale + +### Why Ringtail Over ML-DSA for Threshold Signatures? + +ML-DSA (formerly Dilithium) is NIST-approved but was designed for single-signer scenarios. Converting ML-DSA to threshold form requires complex MPC protocols with significant overhead. Ringtail was purpose-built for threshold signing: + +- **Native Threshold Support**: Ringtail's algebraic structure directly supports threshold operations without generic MPC protocols +- **Two-Round Protocol**: Only 2 communication rounds for distributed signing (vs. 5+ for generic threshold ML-DSA) +- **Same Security Foundation**: Based on Ring-LWE, sharing security assumptions with NIST-approved ML-KEM and ML-DSA + +### Why Hybrid Mode? + +The hybrid BLS+Ringtail approach provides: + +1. **Immediate Classical Security**: BLS signatures provide proven security against classical adversaries +2. **Future Quantum Security**: Ringtail component provides protection against future quantum attacks +3. **Graceful Migration**: Validators can progressively upgrade to full quantum-safe mode +4. **Backwards Compatibility**: Classical clients can still verify the BLS component + +### Why Not ML-KEM for Key Exchange? + +ML-KEM is excellent for key encapsulation but Warp messages require digital signatures (authentication), not key exchange (confidentiality). Ringtail provides post-quantum signatures directly. + +--- + +## Backwards Compatibility + +- Warp 1.0 clients can verify BLS signatures (unchanged) +- Signature type indicated by codec type ID +- Unknown signature types rejected safely +- Upgrade path: BLS → Hybrid → Ringtail + +--- + +## Copyright + +Copyright and related rights waived via [CC0](../LICENSE.md). diff --git a/LPs/lp-7000-a-chain-ai-attestation-specification.md b/LPs/lp-7000-a-chain-ai-attestation-specification.md deleted file mode 100644 index 8217cb7c..00000000 --- a/LPs/lp-7000-a-chain-ai-attestation-specification.md +++ /dev/null @@ -1,422 +0,0 @@ ---- -lp: 7000 -title: A-Chain - Core AI/Attestation Specification -tags: [core, ai, attestation, tee, a-chain] -description: Core specification for the A-Chain (AI Virtual Machine), Lux Network's attestation and AI compute chain -author: Lux Network Team (@luxfi) -discussions-to: https://github.com/luxfi/lps/discussions -status: Review -type: Standards Track -category: Core -created: 2025-12-11 -requires: 0000, 99, 70 -order: 0 ---- - -## Abstract - -LP-5000 specifies the A-Chain (AI Virtual Machine), Lux Network's attestation layer providing network-wide verification of trusted execution environments (TEEs) across all compute classes (CPU, GPU, NPU, ASIC).

Threshold-signature custody for all externally-bridged assets (BTC Taproot MuSig2, ETH/Arb/OP ECDSA-GG21, XRPL Ed25519-FROST, etc.). +2. SwapSigTx issuance—i.e. deterministic, on-chain proof that the quorum of custodial signers has produced a valid spend-signature for a given SwapTx on X-Chain. +3. Autonomous slashing & reward accounting for MPC signers based on service-level compliance. +4. A light-client proof format (MProof) consumable by X-Chain and Z-Chain without full T-Chain sync. + +This LP formalises the VM, transaction formats, validator duties, RPCs and economic parameters that replace the legacy off-chain bridge back-end (`swaps.ts`) with fully decentralised, auditable on-chain logic. + +## 2 Motivation + +The original Lux Bridge relied on: +- a Postgres "swap" table, +- a central key-manager process, and +- a cron-based status poller. + +These create single points of failure and introduce trust in the server operator. +Migrating signature collection and state tracking into a sovereign chain removes those risks and lets any front-end query or drive swaps by standard JSON-RPC or WebSocket streams. +Validators who already stake LUX now earn additional MPC rewards, tightening economic alignment. + +## 3 High-level Architecture + +``` + +---------------------------------------+ + | T-Chain VM | + |---------------------------------------| + | • KeyShareRegistry (G1, G2, PK) | + | • SwapSigTx verifier | + | • SLA / Slashing manager | + | • RewardDistributor | + +------------------+--------------------+ + | + WarpMsg | gRPC /sign_swap(id) + v + +-----------+ +---------------------+ +-----------+ + | X-Chain |<-------| mpckeyd (per signer)|------->| BTC / ETH | + | SwapFx | +---------------------+ | XRPL… | + +-----------+ +-----------+ +``` + +- Each validator must run `mpckeyd`, holding one or more key-shares. +- When an X-Chain `SwapTx` enters PENDING state, validators detect the event through a filtered light-client feed, assemble a threshold signature, and collectively submit `SwapSigTx` on T-Chain. +- Failure to sign before expiry incurs an automated slashing penalty booked by the VM. +- X-Chain trusts T-Chain via a Merkle-mount light-client proof (MProof) – no full sync required. + +## 4 Specification + +### 4.1 Consensus & Validator Set +- **Engine**: Lux consensus++ linear chain (2 s finality). +- **Staking token**: LUX.

We expand on LP-13 by providing an academic-style rationale for adopting CGG21, an overview of its node-level integration in Lux’s MVM, comparisons with prior threshold schemes (GG18, DKLS19, and Ethereum’s threshold cryptography efforts), and a detailed threat model with security assumptions. We also outline a roadmap for a hybrid post-quantum upgrade, incorporating a subset of Ringtail (a lattice-based threshold signature scheme) participants into the signing group to achieve partial post-quantum protection during the transition. + +## Motivation and Rationale for CGG21 + +Figure 1: Concept of a threshold signature. A signature is only produced if a threshold of participants collaborate, mitigating single points of failure. + +Threshold signatures allow a private key’s functionality to be distributed among \(n\) parties such that any quorum of \(t\) (threshold) parties can jointly produce a valid signature, whereas any collusion of fewer than \(t\) cannot [9]. This property greatly enhances security for high-value assets and cross-chain bridges by eliminating any single point of key compromise. + +CGG21, formally known as “UC Non-Interactive, Proactive, Threshold ECDSA with Identifiable Aborts,” is a state-of-the-art threshold ECDSA protocol that combines several desirable features [1]: + +- **Non‑interactive signing**: Only the final round depends on the message, while prior rounds can be pre‑computed offline. This yields a low-latency signing process suitable for time-sensitive blockchain operations. In practice, Lux’s T-Chain nodes can perform most of the computation before a signature is requested, so signing adds minimal delay. +- **Few communication rounds**: CGG21 achieves a signing workflow in as few as 5 rounds (or 8 rounds in an alternate variant), significantly fewer than earlier schemes. Lux’s implementation uses the 5‑round variant to minimize latency, incurring a slight computation overhead only if a signing attempt fails. +- **Identifiable aborts (accountability)**: A key innovation of CGG21 is the ability to identify misbehaving parties if the protocol fails. In earlier threshold ECDSA protocols like GG18, any dishonest participant could simply abort the signing, causing a denial-of-service without penalty [2]. CGG21 remedies this by pinpointing the culprit when a signature share is invalid or withheld. This identifiable abort property deters sabotage by enabling Lux to slash or replace malicious nodes—a crucial feature for an open network of validators. +- **Proactive security with key refresh**: The scheme supports periodic distributed key refreshes that do not change the public key but reshuffle the private key shares. This means T-Chain validators can regularly re-randomize their secret shares (e.g., per epoch), so an adversary cannot slowly compromise shares one by one over time. An attacker must corrupt at least \(t\) nodes within one refresh period to break the key, dramatically reducing the risk of key compromise in long-lived signing groups. +- **Dealerless distributed key generation (DKG)**: CGG21 includes a built-in DKG protocol for key-share distribution. Validators jointly generate the ECDSA private key shares without any trusted dealer, and no single node ever knows the full secret key. This aligns with Lux’s decentralization goals—the T-Chain can initialize or reconfigure signer sets transparently on-chain, avoiding any single point of trust during setup. +- **Universally Composable (UC) security**: The protocol is proven secure in the rigorous UC framework (in the Global Random Oracle model), meaning it securely realizes an ideal threshold signature functionality under composition with other protocols. Its security relies on standard cryptographic hardness assumptions: Strong RSA, Decisional Diffie-Hellman (DDH), the semantic security of Paillier encryption, and a strengthened form of ECDSA’s unforgeability assumption. These assumptions are well-studied and give confidence that no efficient attack is known under classical computing. In particular, CGG21’s reliance on Paillier (an additively homomorphic encryption) enables the distributed multiplication needed for ECDSA signing, while zero-knowledge techniques and verifiable secret sharing enforce correctness. + +Overall, adopting CGG21 in Lux’s bridge architecture provides high security and liveness guarantees (“no surprises” signing that either succeeds or identifies a culprit), suitable performance for real-time signing, and strong theoretical foundations [1]. These advantages justify moving beyond the simpler approaches outlined in LP-13 and embracing an academically vetted scheme that is specifically designed for threshold ECDSA (which, unlike Schnorr-based signatures, is notoriously non-trivial to thresholdize). By using CGG21, Lux positions T-Chain’s multi-party signing at the cutting edge of threshold cryptography research, similar to the “threshold wallets” employed by top custodians. + +## Architecture and Implementation in Lux T-Chain MVM + +**System Overview:** In Lux’s T-Chain (the MPC bridge chain), a committee of validators collaboratively controls bridge accounts using threshold signatures. The Lux MVM (Multiverse Virtual Machine) node software incorporates the CGG21 protocol at the networking and consensus layer. Each T-Chain node holds an encrypted share of the ECDSA private key for each asset or blockchain being bridged. Neither the Lux platform nor any single node ever reconstructs the full private key—all operations are done via distributed computation. + +**Key Generation and Management:** When a new signing group is formed (e.g., rotating the bridge key or adding validators), the nodes run CGG21’s distributed key generation sub-protocol [1]. This protocol uses verifiable secret sharing to distribute shares of a fresh ECDSA private key to all \(n\) participants without revealing the key to anyone. Each node \(i\) obtains a private share \(x_i\), and collectively they define a public key \(X = x·G\) on secp256k1 (where \(G\) is the base point). This public key is published on-chain as the address that holds assets or as the trusted signing authority for bridging. The DKG is dealerless aside from network broadcast and produces commitments and proofs to ensure consistency and correctness of shares for all honest parties. + +The MVM stores each node’s key share in a secure enclave or keystore. For additional safety, validators may split each share among an HSM and a backup service. Periodic key refresh is triggered by the protocol or governance: nodes engage in a 3‑round share refresh that outputs new shares for the same key [1]. This proactive refresh must occur frequently enough so that an adversary cannot compromise \(t\) nodes between refreshes. + +**Signing Process:** To initiate a signing (e.g., releasing funds from the bridge), the T-Chain consensus includes a signing request containing the message hash. Signer nodes then execute the CGG21 signing protocol in two phases [1]: + +- **Offline Pre‑processing:** Nodes asynchronously run pre-computation rounds before any message is known, generating ephemeral values and Paillier-encryption commitments. Lux’s MVM implements this as background tasks that produce pre-signature tokens—partly computed signature shares tied to random nonces and commitments. These tokens are stored locally and exchanged over the T-Chain’s p2p network. +- **Online Signing:** Upon receiving the real message, each node independently combines its pre-signature token with the message hash to compute a signature share without further interaction. In the final round, nodes broadcast their shares and combine them to form the standard ECDSA \((r,s)\) signature [1]. This one-round online phase yields very low latency, typically a few network ticks. +- **Abort Handling:** If a node fails or sends an invalid share, CGG21’s identifiable abort feature reveals the culprit via verifiable commitments [1]. Lux logs this event on-chain, enabling slashing or removal of malicious validators. Honest nodes may retry with a fresh token or pause the bridge if the subgroup is too small to satisfy the threshold. + +The MVM leverages deterministic execution and secure channels (e.g., TLS) to orchestrate each CGG21 round, using optimized native libraries for big‑integer and elliptic‑curve operations. Benchmarks show a 5‑round CGG21 signature completes in a few hundred milliseconds on LAN and under a couple of seconds in geo‑distributed settings [1]. + +## Comparison with Other Threshold Schemes + +**GG18 (Gennaro–Goldfeder 2018):** The first fully distributed \(t\)-of-\(n\) ECDSA scheme [2], GG18 introduced Paillier-based MPC and Gilboa/SPDZ multiplication for threshold signing. While groundbreaking, GG18 lacked identifiable aborts and required ~9 rounds for signing. CGG21 builds on GG18 by adding accountability and reducing online rounds to one, at the cost of extra zero-knowledge proofs. + +**DKLS19 (Doerner–Kondi–Lee–Shelat 2019):** An OT-based threshold ECDSA protocol achieving a 5‑round workflow for general \(t\)-of-\(n\) [3]. DKLS19 reduces ciphertext sizes but typically cannot pre-compute rounds offline, resulting in higher online latency than CGG21’s non-interactive signing. + +**Ethereum Threshold Efforts:** The tBTC bridge initially used a GG18 variant and encountered DoS aborts [6]. Its roadmap includes migrating to Schnorr‑based schemes (e.g., FROST/ROAST) to avoid abort issues [10]. Meanwhile, Eth2 DVT uses threshold BLS (trivially aggregated), but ECDSA threshold remains essential for external-chain compatibility. + +CGG21 offers a compelling balance of low latency, accountability, and strong UC security, positioning Lux ahead of existing Ethereum threshold deployments. + +## Security Model and Assumptions + +**Threat Model:** We assume a malicious adversary that can adaptively corrupt up to \(f = t-1\) of \(n\) signer nodes, enabling arbitrary deviations. The network may reorder or delay messages, but will eventually deliver them. No trusted dealer exists—DKG and signing are fully distributed [1]. + +**Security Guarantees:** CGG21 UC‑securely realizes an ideal threshold signature functionality [1]. Forgery requires either breaking ECDSA (discrete logarithm on secp256k1), Paillier semantic security (composite residuosity), Strong RSA, or DDH. A corrupted set of fewer than \(t\) nodes cannot learn the private key or produce a valid signature. + +**Operational Security:** Threshold protocol messages must use authenticated, encrypted channels to prevent spoofing. Validator key shares reside in secure enclaves or HSMs, and audit logs record protocol transcripts. Identifiable aborts and on-chain slashing deter malicious behavior. + +## Future Roadmap: Hybrid Post-Quantum Threshold Upgrade + +To mitigate future quantum threats, Lux plans a hybrid ECDSA/PQ threshold scheme. We will integrate Ringtail—a lattice-based 2‑round threshold signature based on LWE [7]—by augmenting the signer set with a random subset performing PQ signing. + +During an interim phase, each bridge operation will produce both a CGG21 ECDSA signature and a Ringtail PQ signature. The PQ signature serves as a fallback until on-chain enforcement is viable. As validators opt into PQ signing, governance will mandate hybrid signatures, gradually transitioning Lux’s bridge to quantum-resistant security without service interruption. + +## Implementation Status + +The CGG21/CMP protocol is fully implemented and production-ready in the Lux threshold cryptography library: +- Repository: `github.com/luxfi/threshold` +- Package: `protocols/cmp` +- Status: Production-ready with 100% test coverage +- Testing: Zero skipped tests, comprehensive benchmarks +- Features: Complete CGG21 implementation with all sub-protocols + +Related implementations: +- **MPC-LSS** (LP-103): Dynamic resharing capabilities in `protocols/lss` +- **FROST** (LP-104): Schnorr/EdDSA threshold signatures in `protocols/frost` +- **Supporting Libraries**: Paillier encryption, zero-knowledge proofs, MTA protocols + +## Conclusion + +This draft LP specifies the integration of CGG21 threshold ECDSA into Lux's T-Chain, delivering low-latency non-interactive signing, identifiable aborts, proactive key refresh, and strong UC security. Our comparison shows CGG21's advantages over GG18, DKLS19, and early Ethereum threshold deployments. We also chart a path toward hybrid post-quantum threshold signing with Ringtail, ensuring Lux's bridges remain secure against both current and future adversaries. + +The complete implementation is available at `github.com/luxfi/threshold` with comprehensive test coverage and production-ready code. + +## References + +1.

LSS is a foundational threshold signature protocol that enables dynamic resharing - the ability to change the participant set and threshold without changing the public key. This capability is crucial for long-lived systems where validator sets change over time. + +**Enhancement over Original Paper**: While Vishnu's original LSS paper described a trusted dealer setup, our implementation enhances this with a fully distributed key generation (DKG) protocol, eliminating any single point of trust. This makes LSS suitable for trustless environments while maintaining all dynamic resharing capabilities. + +LSS complements the CGG21 (CMP) protocol described in LP-14 by providing a simpler, more flexible approach to threshold signatures with unique dynamic properties not available in ECDSA-based schemes. + +## Motivation and Rationale + +While CGG21/CMP provides state-of-the-art threshold ECDSA with identifiable aborts, there are scenarios where a simpler, more flexible approach is beneficial: + +1. **Dynamic Participant Sets**: LSS uniquely supports changing the set of participants (adding/removing parties) while maintaining the same public key +2. **Threshold Flexibility**: The threshold can be adjusted dynamically without regenerating keys +3. **Protocol Simplicity**: LSS uses straightforward polynomial secret sharing without complex MPC protocols +4. **Foundation for Higher Protocols**: LSS serves as a building block for more complex threshold schemes + +These properties make LSS ideal for: +- Validator rotation in blockchain networks +- Long-lived custody solutions where signers change +- Disaster recovery scenarios requiring participant replacement +- Gradual migration between signer sets + +## Technical Specification + +### Core Concepts + +LSS is based on Shamir's Secret Sharing using polynomial interpolation over a finite field. The key innovation is the resharing protocol that enables dynamic reconfiguration. + +#### Mathematical Foundation + +Given a secret `s` and threshold `t`: +1. Construct a random polynomial `f(x)` of degree `t-1` where `f(0) = s` +2. Each party `i` receives share `f(i)` +3. Any `t` parties can reconstruct `s` using Lagrange interpolation +4. The public key `Y = s·G` remains constant across resharing + +#### Key Properties + +- **Information Theoretic Security**: No computational assumptions required for secrecy +- **Perfect Secrecy**: Fewer than `t` shares reveal nothing about the secret +- **Homomorphic**: Operations on shares correspond to operations on secrets +- **Verifiable**: Using Feldman VSS, shares can be verified without revealing the secret + +### Protocol Phases + +#### 1.

Compute public key: Y = Σⱼ Cⱼ₀ +4. Store configuration with share xᵢ and public key Y + +Output: Distributed key with no single party knowing the secret +``` + +This DKG protocol ensures: +- **No Trusted Dealer**: Secret is generated collectively +- **Verifiability**: All shares can be verified using commitments +- **Robustness**: Protocol completes despite t-1 malicious parties + +#### 2. Signing + +``` +Input: Message m, signers S ⊆ P with |S| ≥ t +Output: Schnorr signature (R, z) + +1. Nonce Generation: + Each signer i ∈ S: + a. Generate random kᵢ + b. Compute Rᵢ = kᵢ·G + c.

Share Distribution: + Each party pᵢ ∈ P_old: + a. Create polynomial fᵢ(x) where fᵢ(0) = sᵢ_old + b. Compute shares sᵢⱼ = fᵢ(j) for each pⱼ ∈ P_new + c. Send sᵢⱼ to pⱼ with commitments + +2.

This simplifies long‑lived operations, reduces operational risk, and complements ECDSA‑focused protocols (CGG21) with a simpler Schnorr‑style alternative. + +## Backwards Compatibility + +This LP introduces an additive threshold scheme. Existing components continue to operate unchanged. Systems MAY adopt LSS gradually; keys and interfaces are versioned via the `Generation` counter to avoid ambiguity during migrations. + +## Security Considerations + +Follow the Security Model above. In particular: use authenticated channels, enforce generation counters to prevent replay, schedule proactive resharing to limit exposure, and verify shares via VSS commitments.

This is essential because: - -1. **Trade Secrets**: Model weights are the core IP of AI companies; they cannot be published for verification -2. **Regulatory Need**: EU AI Act requires output traceability, creating a tension with IP protection -3. **ZK Resolution**: ZK proofs resolve this tension -- prove the relationship without the exposure - -The proof circuit works by: -1. Taking model weights hash as private input -2. Taking model seal commitment as public input -3. Proving that `Poseidon2(weights) == committed_hash` AND `model(input) == output` -4. Verifying via LP-0510 STARK verification - -### Why Separate from LP-0535 - -LP-0535 provides the general-purpose data sealing primitive. LP-7110 adds domain-specific semantics for AI and media that would be inappropriate in the base protocol: - -- Model manifests with ML-specific fields -- Output attestation with inference configuration -- Media seals with device attestation and GPS data -- Deepfake detection integration -- Regulatory compliance reporting - -This layered approach keeps the base protocol simple while enabling rich application semantics. - -### C2PA Interoperability - -The Coalition for Content Provenance and Authenticity (C2PA) is the emerging industry standard for content credentials. LP-7110 is designed to be **complementary**, not competing: - -- Media seals can import C2PA manifests during creation -- Media seals can export C2PA-compatible manifests for distribution -- The key difference: LP-7110 provides decentralized, on-chain verification where C2PA relies on centralized trust anchors - -## Backwards Compatibility - -This LP introduces new A-Chain/Z-Chain interfaces that extend the LP-0535 seal protocol. All operations use LP-0535 seal primitives internally, ensuring full compatibility with the base receipt and seal infrastructure. - -Existing A-Chain attestation (LP-7000) and training ledger (LP-7102) records are compatible and can be referenced by model seals. - -## Test Cases - -### Model Provenance Tests - -| Test | Description | Expected | -|------|-------------|----------| -| `TestSealModel` | Seal a model with full manifest | Model seal created, weights hash recorded | -| `TestSealModelConfidential` | Seal model with FHE-encrypted weights | Weights hash not visible in plaintext | -| `TestSealFineTune` | Register fine-tuned model from base | Derivative lineage established | -| `TestVerifyModelIntegrity` | Check model against seal | Integrity confirmed | -| `TestVerifyTamperedModel` | Check modified model against seal | Integrity violation detected | - -### Output Attestation Tests - -| Test | Description | Expected | -|------|-------------|----------| -| `TestSealOutput` | Seal output with model reference | Output seal created with provenance | -| `TestSealVerifiedOutput` | Seal output with ZK execution proof | Verified provenance chain | -| `TestGetProvenance` | Query full provenance DAG | Model + dataset seals returned | -| `TestCrossModelProvenance` | Output from model trained on another model's outputs | Multi-hop provenance tracked | - -### Media Authentication Tests - -| Test | Description | Expected | -|------|-------------|----------| -| `TestSealOriginalMedia` | Seal photo at capture with device attestation | Original media seal created | -| `TestSealEditedMedia` | Seal edited version of photo | Edit chain extended | -| `TestGetEditHistory` | Query edit chain | Ordered seal list returned | -| `TestDeclareAIGenerated` | Flag media as AI-generated | AI flag set with model reference | -| `TestIsAIGenerated` | Query AI generation status | Correct flag returned | - -### Deepfake Detection Tests - -| Test | Description | Expected | -|------|-------------|----------| -| `TestRegisterDetector` | Register detection model | Detector registered with accuracy | -| `TestSubmitDetectionResult` | Submit analysis result | Result sealed and anchored | -| `TestMultipleDetectors` | Multiple detectors analyze same media | All results queryable | - -### Compliance Tests - -| Test | Description | Expected | -|------|-------------|----------| -| `TestEUAIActReport` | Generate compliance report | All fields populated | -| `TestC2PAExport` | Export media seal as C2PA manifest | Valid C2PA v2.0 format | -| `TestComplianceCheck` | Check provenance against EU AI Act | Compliance status + gaps | - -## Reference Implementation - -Implementation locations: - -**A-Chain (AI attestation layer)**: -``` -vms/attestation/content/ -├── model_seal.go // Model sealing and verification -├── output_attestation.go // Output sealing with ZK proofs -├── media_authentication.go // Media sealing and lifecycle -├── deepfake_anchoring.go // Detection result integration -├── compliance.go // Regulatory compliance reporting -├── c2pa_interop.go // C2PA manifest import/export -├── provenance_graph.go // DAG traversal and queries -├── content_test.go // Unit tests -└── content_integration_test.go // Integration tests -``` - -**Z-Chain (proof verification)**: -``` -precompile/contracts/contentproof/ -├── execution_proof.go // ZK execution proof verification -├── media_proof.go // Media authenticity proofs -└── contentproof_test.go // Tests -``` - -## Security Considerations - -### Model Weight Confidentiality - -Confidential model seals use FHE to encrypt the weights hash. The security of model IP depends on: -1. FHE key management (LP-203, K-Chain) -2. Threshold decryption prevents single-party compromise -3. ZK proofs never require decryption of the weights hash - -### Device Attestation Trust - -Media seals with device attestation depend on the trustworthiness of the capture device's secure enclave. Known limitations: -1. Rooted/jailbroken devices can forge attestations -2. Emulated devices can produce valid-looking attestations -3. Mitigation: Cross-reference with multiple signals (GPS, network time, device reputation) - -### Deepfake Detection Arms Race - -The deepfake detection integration does NOT claim to solve deepfake detection. It provides: -1. Ground truth for original media (sealed at capture) -2. Auditable detection results from multiple registered detectors -3. Temporal ordering of detection claims - -Detection accuracy is the responsibility of the registered detector models, not the protocol. - -### AI-Generated Content Disclosure - -Self-declaration of AI-generated content (`declareAIGenerated`) is voluntary. Malicious actors will not self-declare. The protocol's value is in: -1. Enabling honest actors to transparently declare AI content -2. Providing verifiable provenance for those who participate -3. Creating a growing "verified authentic" corpus for comparison -4. Supporting regulatory compliance for responsible AI developers - -### Cross-Standard Metadata Leakage - -When exporting to C2PA or other formats, care must be taken not to include metadata that was intended to be private. The compliance interface strips FHE-encrypted fields before export. - -## Economic Impact - -### Enterprise Value Proposition - -| Segment | Value | Mechanism | -|---------|-------|-----------| -| AI Governance | Reduced regulatory risk | Automated compliance reporting | -| Media & News | Restored audience trust | Verifiable content provenance | -| Cyber Insurance | Faster claims processing | Sealed evidence chains | -| Legal & Forensics | Court-admissible proofs | Cryptographic evidence | -| Brand Protection | Counterfeit detection | Original media verification | - -### Fee Model - -Content provenance sealing is expected to process high volumes at low per-unit cost: - -- Single media seal: ~$0.02 -- Model seal: ~$0.05 (larger manifest) -- Batch output sealing: ~$0.005/output (at 1000+ batch) -- Compliance report: ~$0.01 - -## Open Questions - -1. **ZK Execution Proof Feasibility**: Full model execution proofs (proving `model(input) = output`) are currently prohibitively expensive for large models.

Stake-and-slash on accuracy claims? - -3. **C2PA Governance Alignment**: Should Lux seek formal C2PA membership to influence cross-standard compatibility? - -4. **Media Capture SDK**: Should LP-7110 define a reference SDK for camera/device integration, or leave this to implementers? - -## Copyright - -Copyright and related rights waived via [CC0](https://creativecommons.org/publicdomain/zero/1.0/). diff --git a/LPs/lp-7200-ai-mining-standard.md b/LPs/lp-7200-ai-mining-standard.md deleted file mode 100644 index cfbd487a..00000000 --- a/LPs/lp-7200-ai-mining-standard.md +++ /dev/null @@ -1,477 +0,0 @@ ---- -lp: 7200 -title: AI Mining Standard -description: Quantum-safe AI mining protocol with cross-chain Teleport integration for Lux ecosystem -author: Hanzo AI (@hanzoai), Lux Network (@luxfi), Zoo Labs (@zoolabs) -discussions-to: https://github.com/luxfi/lps/discussions -status: Implemented -type: Standards Track -category: Core -created: 2025-01-15 -requires: 0004, 0005 -tags: [ai, consensus] -activation: - flag: lp-2000-ai-mining - hfName: "ai-mining" - activationHeight: "0" -order: 200 ---- - -## Abstract - -This LP defines the **Lux AI Mining Standard**, a quantum-safe protocol for mining AI compute rewards on the Lux L1 network using ML-DSA (FIPS 204) wallets. The protocol integrates with the Teleport bridge to enable seamless transfer of AI mining rewards to supported EVM L2 chains including Hanzo EVM (Chain ID: 36963), Zoo EVM (Chain ID: 200200), and Lux C-Chain (Chain ID: 96369). - -## Activation - -| Parameter | Value | -|--------------------|--------------------------------| -| Flag string | `lp2000-ai-mining` | -| Default in code | **false** until block TBD | -| Deployment branch | `v0.0.0-lp2000` | -| Roll‑out criteria | Testnet validation complete | -| Back‑off plan | Disable via flag | - -## Motivation - -The convergence of AI and blockchain requires a native protocol for mining AI compute rewards. Current solutions lack: - -1. **Quantum Safety**: No protection against quantum computer attacks on mining signatures -2. **Native L1 Support**: AI rewards exist only as ERC-20 tokens without native L1 integration -3. **Cross-Chain Interoperability**: Fragmented reward distribution across chains -4. **Consensus Integration**: No direct integration with BFT consensus for reward finality - -This LP addresses these gaps by establishing a quantum-safe mining protocol at the L1 layer with native Teleport bridge integration. - -## Specification - -### 1.

NVTrust Chain-Binding Double-Spend Prevention - -The core mechanism preventing AI work from being claimed on multiple chains. - -#### 6.1 Design Principle - -We avoid double-spend by **binding each unit of AI work to a specific chain before the compute runs**, and then having the GPU's confidential-compute environment sign an attested receipt that includes that chain ID. - -That receipt is: -- **Unique** (per device + nonce) -- **Bound to one chain** (via chain_id in the attested context) -- **Signed by NVIDIA's NVTrust root** - -So you cannot take one chunk of work and mint it on multiple chains without re-doing the compute. - -#### 6.2 Work Context (Pre-Compute Commitment) - -When a miner wants to do AI work, their node commits to a target chain: - -```rust -pub struct WorkContext { - pub chain_id: ChainId, // HANZO / LUX / ZOO - pub job_id: [u8; 32], // Specific workload or block height - pub model_hash: [u8; 32], // Which model - pub input_hash: [u8; 32], // Which data / prompt - pub device_id: [u8; 32], // GPU identity - pub nonce: [u8; 32], // Unique per job - pub timestamp: u64, // Unix timestamp -} -``` - -This context is passed into the GPU's NVTrust enclave as job metadata. The miner has effectively said: *"This work is for this chain, this job, with this model + input."* - -**Reference Implementation:** -- [`lux/ai/pkg/attestation/nvtrust.go`](https://github.com/luxfi/ai/blob/main/pkg/attestation/nvtrust.go) - -#### 6.3 GPU TEE Execution (NVTrust) - -Inside the TEE, the GPU: -1. Verifies the code + model hashes (no tampering) -2. Runs the AI workload (inference / training) -3. Creates a work receipt: - -```rust -pub struct WorkReceipt { - pub context: WorkContext, // Includes chain_id, job_id, etc. - pub result_hash: [u8; 32], // Hash of the output - pub work_metrics: WorkMetrics, // FLOPs, steps, tokens, etc. - pub device_id: [u8; 32], // GPU identity -} - -pub struct WorkMetrics { - pub flops: u64, // Floating point operations - pub tokens_processed: u64, // For LLM inference - pub compute_time_ms: u64, // Execution time - pub memory_used_mb: u64, // Peak VRAM usage -} -``` - -The NVTrust enclave signs `WorkReceipt` with its attested key: - -```rust -pub struct AttestedReceipt { - pub receipt: WorkReceipt, - pub nvtrust_signature: Vec, // Rooted in NVIDIA hardware attestation - pub spdm_evidence: SPDMEvidence, // SPDM measurement response -} -``` - -This is cryptographic proof that: *"This exact device ran this exact workload with this exact context."* - -**Reference Implementation:** -- [`lux/ai/pkg/attestation/attestation.go`](https://github.com/luxfi/ai/blob/main/pkg/attestation/attestation.go) -- [`shinkai/hanzo-node/hanzo-bin/hanzo-node/src/security/tee_attestation.rs`](https://github.com/hanzoai/node/blob/main/hanzo-bin/hanzo-node/src/security/tee_attestation.rs) - -#### 6.4 Chain Verification and Minting - -When the miner submits the receipt to a chain: - -```rust -pub fn verify_and_mint( - receipt: &AttestedReceipt, - spent_set: &mut HashSet<[u8; 32]>, - expected_chain_id: ChainId, -) -> Result { - // Step 1: Verify NVTrust signature is valid - verify_nvtrust_signature(&receipt)?; - - // Step 2: Verify chain_id matches this chain - if receipt.receipt.context.chain_id != expected_chain_id { - return Err(MiningError::WrongChain); - } - - // Step 3: Compute unique key - let key = blake3::hash(&[ - &receipt.receipt.context.device_id[..], - &receipt.receipt.context.nonce[..], - &(receipt.receipt.context.chain_id as u32).to_le_bytes()[..], - ]); - - // Step 4: Check spent set (double-spend prevention) - if spent_set.contains(&key.into()) { - return Err(MiningError::AlreadyMinted); - } - - // Step 5: Mark as spent and mint - spent_set.insert(key.into()); - let reward = calculate_reward(&receipt.receipt.work_metrics); - Ok(reward) -} -``` - -**Reference Implementation:** -- [`lux/ai/pkg/rewards/rewards.go`](https://github.com/luxfi/ai/blob/main/pkg/rewards/rewards.go) -- [`shinkai/hanzo-node/hanzo-libs/hanzo-mining/src/ledger.rs`](https://github.com/hanzoai/node/blob/main/hanzo-libs/hanzo-mining/src/ledger.rs) - -#### 6.5 Multi-Chain Mining (Same GPU, No Double-Spend) - -The same GPU can mine for Hanzo, Lux, Zoo, etc., but: -- Each chain requires a **separate job** with a **different chain_id** in the NVTrust context -- Each job produces a **different attested receipt** with a different `(chain_id, job_id, nonce)` triple - -| GPU | Job 1 | Job 2 | Job 3 | -|-----|-------|-------|-------| -| H100-001 | Hanzo (36963) | Zoo (200200) | Lux (96369) | -| H100-001 | nonce: 0x1a... | nonce: 0x2b... | nonce: 0x3c... | -| H100-001 | Receipt A | Receipt B | Receipt C | - -**No "copy-paste" mining** - you can't run one workload and cash it in on three chains. - -#### 6.6 Supported GPUs for NVTrust - -| GPU Model | CC Support | Trust Score | -|-----------|------------|-------------| -| H100 | Full NVTrust | 95 | -| H200 | Full NVTrust | 95 | -| B100 | Full NVTrust + TEE-I/O | 100 | -| B200 | Full NVTrust + TEE-I/O | 100 | -| GB200 | Full NVTrust + TEE-I/O | 100 | -| RTX PRO 6000 | NVTrust | 85 | -| RTX 5090 | No CC | Software only (60) | -| RTX 4090 | No CC | Software only (60) | - -### 7.

Reward entry added to global ledger -5. 2-round BFT finality confirms reward -6. Teleport bridge unlocks cross-chain transfers - -## Rationale - -### Why ML-DSA? -NIST selected ML-DSA (formerly CRYSTALS-Dilithium) as the primary post-quantum signature standard. Level 3 provides 128-bit quantum security matching current blockchain standards. - -### Why Teleport over Traditional Bridges? -Teleport uses native L1 finality rather than relying on external validators, providing stronger security guarantees for AI reward transfers. - -### Why Separate L1 Mining? -Native L1 mining enables direct consensus integration without smart contract overhead, providing faster finality and lower costs for high-frequency mining operations. - -## Backwards Compatibility - -This LP introduces new functionality without breaking existing features: - -- Existing wallets continue to work on EVM chains -- Legacy transactions remain valid -- New ML-DSA addresses coexist with ECDSA addresses -- Teleport is opt-in for cross-chain transfers - -## Test Cases - -Test vectors are provided in the reference implementation: - -```bash -cd hanzo-libs/hanzo-mining -cargo test -``` - -**Key Test Cases:** -1. `test_wallet_creation` - ML-DSA key generation -2. `test_wallet_signing` - Signature creation/verification -3. `test_ledger_operations` - Reward tracking -4. `test_teleport_transfer` - Cross-chain transfers -5. `test_bridge_creation` - Full bridge integration - -## Reference Implementation - -| Component | Location | -|-----------|----------| -| Mining Wallet | [`hanzo-mining/src/wallet.rs`](https://github.com/hanzoai/node/blob/main/hanzo-libs/hanzo-mining/src/wallet.rs) | -| Global Ledger | [`hanzo-mining/src/ledger.rs`](https://github.com/hanzoai/node/blob/main/hanzo-libs/hanzo-mining/src/ledger.rs) | -| EVM Integration | [`hanzo-mining/src/evm.rs`](https://github.com/hanzoai/node/blob/main/hanzo-libs/hanzo-mining/src/evm.rs) | -| Bridge Protocol | [`hanzo-mining/src/bridge.rs`](https://github.com/hanzoai/node/blob/main/hanzo-libs/hanzo-mining/src/bridge.rs) | -| Solidity Precompile | [`lux/precompiles/AIMining.sol`](~/work/lux/standard/contracts/precompiles/AIMining.sol) | - -## Security Considerations - -### Quantum Safety -ML-DSA provides NIST Level 3 (128-bit) quantum security.

Dual-Purpose Architecture (Z/A)**: Separating privacy (Z-Chain) from AI attestation (A-Chain) allows each to optimize for their specific use cases while sharing security infrastructure. - -**2. ZK-SNARKs over STARKs**: Groth16-based proofs offer smaller proof sizes (288 bytes vs 50KB+) and faster verification (~6ms vs ~50ms), critical for on-chain privacy. - -**3. FHE for Computation-Heavy Privacy**: Some operations benefit from keeping data encrypted during computation rather than using ZK proofs, especially for ML inference on private data. - -**4. TEE Integration**: Hardware enclaves provide a pragmatic bridge for complex computations that are impractical to express as circuits. - -### Alternatives Considered - -- **Single-Purpose Chain**: Rejected as it wouldn't capture synergies between privacy and AI use cases -- **Pure STARK-based**: Rejected due to larger proof sizes and verification costs -- **Pure FHE**: Rejected as too slow for real-time applications -- **No TEE**: Rejected as some AI workloads require practical execution environments - -## Backwards Compatibility - -**Migration Path**: -- Existing Lux smart contracts can interact with Z-Chain via bridge interface -- A-Chain attestations can be verified on C-Chain through cross-chain messaging -- Legacy applications don't require modification - -**Compatibility Considerations**: -- EVM compatibility for Z-Chain smart contracts -- Standard REST/gRPC APIs for A-Chain attestation submission -- Interoperability with existing ZK proof systems (Groth16, PLONK) - -**Breaking Changes**: None for existing applications.

The precompile provides compact 64-byte threshold signatures with a two-round signing protocol, offering lower gas costs than ECDSA-based threshold schemes. + +## Motivation + +### The Threshold Signature Challenge + +Multi-party signatures are essential for: +1. **Distributed Trust**: No single party controls the signing key +2. **Threshold Policies**: Require t-of-n parties to authorize (e.g., 3-of-5) +3. **Operational Resilience**: Function with n-t offline parties +4. **Attack Resistance**: Adversary needs to compromise ≥t parties + +Existing threshold schemes have limitations: +- **ECDSA Threshold (CGGMP21)**: Complex multi-round protocol, higher gas costs +- **BLS Threshold**: Requires trusted dealer, pairing-based cryptography +- **Native Multisig**: Linear verification cost, not aggregatable + +### Why FROST? + +FROST (Flexible Round-Optimized Schnorr Threshold) provides unique advantages: + +1. **Efficiency**: Two-round signing protocol (commitment + response) +2. **Compact Signatures**: 64 bytes (standard Schnorr), same as single-party +3. **Bitcoin Compatibility**: Native support for Taproot (BIP-340/341) multisig +4. **Ed25519 Support**: Works with Solana, Cardano, TON, Polkadot signatures +5. **No Trusted Dealer**: Distributed key generation without central party +6. **Standards-Based**: IETF draft-irtf-cfrg-frost specification + +### Use Cases + +- **Bitcoin Taproot Multisig**: Quantum-resistant alternative to classical multisig +- **Cross-Chain Bridges**: Efficient threshold control of bridge assets +- **DAO Governance**: Council-based threshold voting and execution +- **Validator Signing**: Threshold validator signatures for consensus +- **Enterprise Custody**: Multi-party institutional wallet control + +## Specification + +### Precompile Address + +``` +0x020000000000000000000000000000000000000C +``` + +### Input Format + +The precompile accepts a packed binary input: + +| Offset | Length | Field | Description | +|--------|--------|-------|-------------| +| 0 | 4 | `threshold` | Required number of signers (big-endian uint32) | +| 4 | 4 | `totalSigners` | Total number of participants (big-endian uint32) | +| 8 | 32 | `aggregatePublicKey` | Aggregated threshold public key | +| 40 | 32 | `messageHash` | SHA-256 hash of message being verified | +| 72 | 64 | `signature` | Schnorr signature (R ‖ s) | + +**Total size**: 136 bytes (fixed) + +### Signature Format + +FROST produces standard Schnorr signatures (BIP-340 format): +- **R** (32 bytes): Nonce commitment point (x-coordinate only) +- **s** (32 bytes): Signature scalar + +The signature is indistinguishable from a single-party Schnorr signature. + +### Output Format + +32-byte word: +- `0x0000000000000000000000000000000000000000000000000000000000000001` - signature valid +- `0x0000000000000000000000000000000000000000000000000000000000000000` - signature invalid + +### Gas Cost + +``` +gas = BASE_COST + (totalSigners * PER_SIGNER_COST) + +Where: + BASE_COST = 50,000 gas + PER_SIGNER_COST = 5,000 gas per participant +``` + +**Examples:** +- 2-of-3 threshold: 50,000 + (3 × 5,000) = 65,000 gas +- 3-of-5 threshold: 50,000 + (5 × 5,000) = 75,000 gas +- 5-of-7 threshold: 50,000 + (7 × 5,000) = 85,000 gas +- 10-of-15 threshold: 50,000 + (15 × 5,000) = 125,000 gas + +### Solidity Interface + +```solidity +// SPDX-License-Identifier: MIT +pragma solidity ^0.8.24;

discrete log assumption (less general) +- **Pedersen VSS**: More complex, computationally hiding + +#### Blinding Technique + +**Chosen: Multiplicative Blinding with Random Polynomials** + +**Rationale:** +- Information-theoretically secure (unconditional security) +- Composable with standard secret sharing +- Efficient computation (scalar multiplications) +- Proven secure in LSS paper + +**How It Works:** +``` +Blind: a·w (random w masks a) +Inverse blind: (q·w)^(-1) (removes w without revealing a) +Final share: a'_j = (a·w)·q_j·z_j where z = (q·w)^(-1) +``` + +## Backwards

beyond the general security model. + +### T1: Adaptive Adversary Share Accumulation + +**Threat**: An adversary corrupts different parties over time, accumulating shares across key generations. + +**Analysis**: If adversary corrupts parties {P1, P2} in generation g1, then {P3, P4} in generation g2, they may hold shares that together exceed the threshold. + +**Mitigation**: +- Proactive refresh MUST be performed at regular intervals (RECOMMENDED: every 43,200 blocks / ~1 day) +- Refresh invalidates all previous-generation shares +- Implementations MUST track share generation numbers +- Cross-generation share reconstruction MUST fail + +```go +// Share generation binding +type BoundShare struct { + Share *big.Int + Generation uint32 + KeyID KeyID +} + +func (s *BoundShare) Verify(expectedGen uint32) error { + if s.Generation != expectedGen { + return ErrGenerationMismatch // Prevents cross-gen attacks + } + return nil +} +``` + +### T2: Rogue Key Attack on FROST DKG + +**Threat**: Malicious party chooses their polynomial coefficients after seeing honest parties' commitments, biasing the resulting public key. + +**Analysis**: In FROST DKG Round 1, if an adversary waits to see all commitments before submitting theirs, they can compute coefficients that result in a public key with a known discrete log relationship to another key they control. + +**Mitigation**: +- FROST DKG MUST use a commit-then-reveal structure +- Round 1 MUST collect hashed commitments H(C_i) before revealing C_i +- Implementations MUST reject late submissions +- Proof of knowledge MUST bind the commitment + +```go +// Rogue key prevention via commit-reveal +type DKGCommitReveal struct { + // Phase 1: Submit hash + CommitHash [32]byte // H(commitment || decommit_key) + + // Phase 2: Reveal (after all hashes collected) + Commitment []byte + DecommitKey [32]byte + + // Proof of knowledge prevents rogue key + ProofOfKnowledge *SchnorrProof +} +``` + +### T3: Nonce Reuse in Threshold ECDSA + +**Threat**: If the same nonce k is used for two different messages, the private key can be recovered. + +**Analysis**: Given signatures (r, s1) and (r, s2) on messages m1 and m2 with same nonce: +``` +k = (m1 - m2) / (s1 - s2) mod n +x = (s1 * k - m1) / r mod n +``` + +**Mitigation**: +- CGGMP21 MUST use pre-signed nonces computed during keygen +- Each nonce MUST be bound to a specific session ID +- Implementations MUST track used nonces and reject duplicates +- Nonces MUST be derived deterministically from session entropy + +```go +// Nonce binding prevents reuse +type BoundNonce

+``` + +### T4: Grinding Attack on Session ID Selection + +**Threat**: Adversary manipulates session ID generation to produce IDs that bias signing outcomes. + +**Analysis**: If session IDs are not properly randomized, an adversary might generate many candidate sessions and select one with favorable properties. + +**Mitigation**: +- Session IDs MUST include contributions from multiple parties +- Session ID = H(request_hash || block_hash || participant_nonces) +- No single party can control the session ID +- Implementations SHOULD use commit-reveal for participant nonces + +### T5: Denial of Service via Signing Queue Flooding + +**Threat**: Adversary submits many signature requests to exhaust signer resources. + +**Analysis**: Each signing session requires signers to perform expensive operations. An adversary with sufficient funds could degrade service quality. + +**Mitigation**: +- Base fee MUST be economically significant (0.1 LUX minimum) +- Dynamic fee market SHOULD increase fees under load +- Per-key rate limiting MUST be enforced (RECOMMENDED: 10 requests/block) +- Signer resource quotas MUST be implemented + +```go +// Rate limiting per key +type RateLimiter struct { + RequestsPerBlock map[KeyID]uint32 + MaxPerBlock uint32 // Default: 10 +} + +func (r *RateLimiter) Allow(keyID KeyID, block uint64) bool { + count := r.RequestsPerBlock[keyID] + if count >= r.MaxPerBlock { + return false + } + r.RequestsPerBlock[keyID]++ + return true +} +``` + +### T6: Sybil Attack on Signer Selection + +**Threat**: Adversary creates multiple signer identities to gain disproportionate influence in key generation. + +**Analysis**: If signer selection is based purely on stake, an adversary with N * MinStake could control N signer slots. + +**Mitigation**: +- Minimum stake MUST be set high enough to limit Sybil economics (10,000 LUX) +- Signer selection SHOULD incorporate performance history +- Geographic and organizational diversity SHOULD be considered +- Maximum keys per signer MUST be enforced (50 keys) + +### Security Parameter Requirements + +| Parameter | Minimum | Recommended | Maximum | +|:----------|:--------|:------------|:--------| +| Threshold (t) | 2 | n/2 + 1 | n - 1 | +| Total Parties (n) | 3 | 7-15 | 100 | +| Refresh Interval | 21,600 blocks | 43,200 blocks | 86,400 blocks | +| Session Timeout | 100 blocks | 300 blocks | 600 blocks | +| Min Signer Stake | 1,000 LUX | 10,000 LUX | - | + +## Interoperability + +This section defines how T-Chain interoperates with other Lux chains and external systems. + +### T-Chain to B-Chain Integration + +T-Chain provides threshold signatures to B-Chain (BridgeVM) for cross-chain asset custody.

MUST be encrypted at rest using validator key material +2. **Memory Protection**: Shares SHOULD be stored in secure memory regions when available +3. **Access Control**: Only ThresholdVM process should access share storage +4. **Backup**: Shares SHOULD be backed up to prevent loss (but backup security critical) + +### Network Security + +1. **Authenticated Channels**: All signer communication MUST use TLS with mutual authentication +2. **Message Integrity**: All protocol messages MUST include authenticated signatures +3. **Replay Protection**: Session IDs and nonces MUST be verified +4. **DoS Mitigation**: Rate limiting on sign requests, session limits per key + +### Operational Security + +1. **Monitoring**: Real-time alerting for failed sessions, slashing events +2. **Incident Response**: Procedures for key rotation on compromise +3. **Audit Logging**: Complete transcript of all protocol messages +4. **Access Review**: Regular review of key owners and delegatees + +### Threat Mitigations + +| Threat | Mitigation | +|--------|------------| +| Key Extraction | Threshold prevents extraction; proactive refresh limits exposure | +| Byzantine Signers | Identifiable abort with slashing | +| Replay Attacks | Unique session IDs, nonce binding | +| Man-in-the-Middle | Authenticated channels, commitment schemes | +| Timing Attacks | Constant-time operations, response jitter | +| Share Leakage | Encrypted storage, proactive refresh | +| Validator Compromise | Minimum overlap requirements for resharing | + +## Economic Impact + +### Fee Structure + +| Operation |

Market**: Should signature fees be dynamic based on demand? + +## Future Work + +1. **Post-Quantum Threshold**: Integrate Ringtail for quantum-safe threshold signatures +2. **Hardware Security Module (HSM) Integration**: Support for HSM-backed shares +3. **Multi-Chain Aggregation**: Sign for multiple chains in single session +4. **Threshold Encryption**: Add threshold decryption capabilities + +##

The protocol leverages Linear Secret Sharing (LSS) with Feldman Verifiable Secret Sharing (VSS) to transition signing authority between generations of validators while preserving the same public key. This eliminates the need for bridge contract updates, asset migrations, or service interruptions when validator sets change. + +The protocol introduces six new transaction types (ReshareInitTx, ReshareCommitTx, ReshareShareTx, ReshareVerifyTx, ReshareActivateTx, ReshareRollbackTx) for orchestrating resharing operations on-chain, an **opt-in signer set model** where first 100 validators join via `lux-cli` without resharing, and a Generation Management system for version tracking and atomic rollback. Resharing is triggered ONLY when a signer slot is replaced (not on validator join). The design achieves zero-downtime rotation, proactive security against mobile adversaries, and maintains t-security throughout all protocol phases. + +## Implementation Status + +| Component | Repository | Path | Status | +|-----------|------------|------|--------| +| BridgeVM (B-Chain) | [luxfi/node](https://github.com/luxfi/node) | [`vms/bridgevm/`](https://github.com/luxfi/node/tree/main/vms/bridgevm) | ✅ Implemented | +| ThresholdVM (T-Chain) | [luxfi/node](https://github.com/luxfi/node) | [`vms/thresholdvm/`](https://github.com/luxfi/node/tree/main/vms/thresholdvm) | ✅ Implemented | +| Threshold Crypto | [luxfi/threshold](https://github.com/luxfi/threshold) | [`pkg/`](https://github.com/luxfi/threshold/tree/main/pkg) | ✅ Implemented | +| Bridge App Client | [luxfi/bridge](https://github.com/luxfi/bridge) | [`app/bridge/src/lib/BridgeRPCClient.ts`](https://github.com/luxfi/bridge/tree/main/app/bridge/src/lib/BridgeRPCClient.ts) | ✅ Implemented | +| CLI Integration | [luxfi/cli](https://github.com/luxfi/cli) | `cmd/bridge/` | 🚧 In Progress | + +**Key Source Files:** +- [BridgeVM RPC handlers](https://github.com/luxfi/node/blob/main/vms/bridgevm/rpc.go) - `bridge_registerValidator`, `bridge_getSignerSetInfo`, `bridge_replaceSigner` +- [BridgeVM core logic](https://github.com/luxfi/node/blob/main/vms/bridgevm/vm.go) - `RegisterValidator()`, `RemoveSigner()`, signer set management +- [Threshold MPC protocol]() - CGGMP21 threshold ECDSA implementation + +## Conformance + +The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC 2119] [RFC 8174] when, and only when, they appear in all capitals, as shown here. + +Implementations claiming conformance to this specification: + +1. **MUST** implement all six reshare transaction types (ReshareInitTx, ReshareCommitTx, ReshareShareTx, ReshareVerifyTx, ReshareActivateTx, ReshareRollbackTx) +2. **MUST** preserve the public key across all generation transitions +3. **MUST** verify Feldman VSS commitments for all received shares +4. **MUST** support atomic rollback to previous generation on failure +5. **MUST** invalidate old shares after successful generation activation +6. **MUST** implement opt-in signer registration (first 100 validators, no reshare on join) +7. **MUST** trigger resharing ONLY on signer slot replacement (not on validator join) +8. **SHOULD** support manual reshare triggers via `lux-cli` +9. **MAY** implement custom threshold computation rules + +## Activation + +| Parameter | Value | +|--------------------|--------------------------------------| +| Flag string | `lp333-dynamic-signer-rotation` | +| Default in code | **false** until block X | +| Deployment branch | `v0.0.0-lp333` | +| Roll-out criteria | 67% validator adoption | +| Back-off plan | Generation rollback to previous set | + +## Motivation + +### The Validator Rotation Problem + +Proof-of-Stake networks experience continuous validator churn as nodes join and leave the active set.

The advantage of A in distinguishing the secret s from a uniformly random element r in Z_q is negligible in the security parameter lambda. + +``` +Adv_A^{secrecy}(lambda) = |Pr[A(View_S) = s] - Pr[A(View_S) = r]| <= negl(lambda) +``` + +*Proof:* +1. The view of coalition S consists of: + - Their shares: {f(i) : i in S} + - Feldman commitments: {C_j = a_j * G : j in [0, t-1]} + +2. Since |S| < t, by information-theoretic security of Shamir's scheme, the shares {f(i) : i in S} can be produced for ANY value s' in Z_q by choosing appropriate coefficients. + +3. The commitments {C_j} reveal only g^{a_j}, not a_j (by DL hardness). + +4. Thus View_S is statistically independent of s. QED. + +**Theorem 2 (Share Verification Soundness):** +Let A be a PPT adversary. The probability that A produces an invalid share s_i' != f(i) that passes Feldman verification is negligible. + +``` +Pr[VerifyShare(s_i', i, {C_j}) = true AND s_i' != f(i)] <= negl(lambda) +``` + +*Proof:* +1. Verification passes iff s_i' * G = sum_{j=0}^{t-1} (i^j * C_j) + +2. Since C_j = a_j * G, the RHS equals (sum_{j=0}^{t-1} a_j * i^j) * G = f(i) * G + +3. For s_i' != f(i) to pass: s_i' * G = f(i) * G + +4. This requires solving the discrete logarithm: given f(i) * G, find s_i' != f(i) such that s_i' * G = f(i) * G + +5. By the binding property of the DL problem in G, this occurs with probability at most 1/q (negligible). QED. + +**Theorem 3 (Resharing Security):** +Let (t_old, n_old) be the old configuration and (t_new, n_new) be the new configuration. Assuming at least t_old honest parties participate in resharing: + +(a) **Correctness:** New shares {a'_j} satisfy f'(0) = f(0) = s (same secret) +(b) **Forward Secrecy:** Old shares are information-theoretically independent of new shares +(c) **Threshold Security:** Any t_new new shares can reconstruct s; fewer cannot + +*Proof of (a):* +1. Each old party i contributes: lambda_i * a_i where lambda_i is the Lagrange coefficient at 0 + +2. Sum of contributions: sum_{i in S_old} (lambda_i * a_i) = f(0) = s (by Lagrange interpolation) + +3. New polynomial f' is constructed such that f'(0) = s and f'(j) = a'_j for new party j + +4. Therefore f'(0) = f(0) = s. QED. + +*Proof of (b):* +1. New shares are derived from fresh randomness (blinding polynomials w, q) + +2. The joint distribution (old_shares, new_shares) factors as: + P(old, new) = P(old) * P(new | f(0)) + +3. Conditioned only on the secret s = f(0), old and new shares are independent. QED. + +*Proof of (c):* +1. New shares lie on a degree-(t_new - 1) polynomial f' + +2. t_new points uniquely determine f', hence f'(0) = s + +3. Fewer than t_new points have infinitely many interpolating polynomials with distinct f'(0) values + +4. Security follows from Shamir's theorem. QED. + +#### 1.2 Lagrange Interpolation + +Lagrange interpolation is the mathematical foundation for reconstructing secrets from shares and for converting shares between different polynomial representations during resharing. + +**Theoretical Background:** + +Given any t points on a polynomial f(x) of degree < t, we can uniquely recover f(x) using Lagrange interpolation.

On-Chain Transaction Types vs Off-Chain Protocol + +**Choice:** Hybrid approach with on-chain coordination and off-chain share distribution. + +**Rationale:** +- On-chain transactions provide auditability and finality +- Off-chain share distribution preserves confidentiality +- Commitments and verifications are public; actual shares are encrypted +- Enables governance oversight without compromising security + +#### 2. Generation-Based Versioning + +**Choice:** Monotonically increasing generation numbers with explicit activation. + +**Rationale:** +- Clear ordering of key configurations +- Atomic transitions (no ambiguous states) +- Simple rollback semantics (revert to generation N) +- Compatible with blockchain's linear history + +#### 3. Validator Set as Default Party Source + +**Choice:** Automatic integration with platform validators. + +**Rationale:** +- Natural alignment with network security model +- Validators already have stake at risk (economic security) +- Automatic rotation with validator set changes +- No separate signer registration required + +#### 4. Feldman VSS over Pedersen VSS + +**Choice:** Feldman VSS for commitment scheme. + +**Rationale:** +- Simpler implementation (no additional blinding) +- Sufficient for our security model (discrete log hardness) +- Lower computational overhead +- Well-established security proofs + +### Trade-off: Coordinator Dependency + +**Chosen Trade-off:** Coordinator-assisted resharing. + +**Why:** A coordinator simplifies liveness guarantees and state synchronization. The coordinator is trusted for liveness only, not secrecy - it never sees plaintext shares. + +**Mitigation:** Coordinator can be replicated or rotated. If coordinator fails, reshare times out and rolls back to previous generation. + +## Backwards Compatibility + +### Existing Systems + +This LP is fully backwards compatible: + +1. **Existing Keys**: Can be migrated to Generation 0 of the new system +2. **Static Threshold Systems**: Continue operating unchanged +3. **Current Signing Protocol**: No changes to sign/verify interface +4. **External Contracts**: Public keys remain stable; no contract updates needed + +### Migration from Static Signers + +Systems using static (non-rotatable) threshold keys can migrate to dynamic signer rotation without key regeneration or service interruption.

Each `ManagedKey` operates independently with its own threshold (t), total party count (n), and signer set, allowing distinct security configurations per bridged asset. High-value assets (e.g., BTC, large USDC pools) use higher thresholds (4-of-7 or 5-of-9) for stronger security, while lower-value or high-frequency assets use reduced thresholds (2-of-3) for faster signing latency. This design isolates key compromise risks, enables flexible governance per asset class, and optimizes performance based on asset risk profiles. The specification covers key naming conventions, threshold selection guidelines, key lifecycle management, signer assignment strategies, cross-key coordination, monitoring, and a complete RPC API for key management operations. + +## Motivation + +### Problem Statement + +Current bridge architectures typically employ a single threshold signature configuration for all assets. This one-size-fits-all approach creates several problems: + +1. **Suboptimal Security-Performance Trade-off**: A single threshold must balance security needs of high-value assets against latency requirements of frequent low-value transfers. A 5-of-9 threshold secure enough for BTC custody imposes unnecessary 800ms latency on $50 USDC transfers. + +2. **Uniform Compromise Impact**: If a universal key is compromised, all bridged assets are at risk simultaneously. There is no compartmentalization of custody risk. + +3. **Inflexible Governance**: Different asset classes may have different stakeholders, compliance requirements, or operational needs. A uniform signer set cannot accommodate these differences. + +4. **Inefficient Resource Allocation**: High-capability signers are required for all operations, even trivial transfers where simpler hardware would suffice. + +### Solution + +Per-asset threshold key management addresses these problems by treating each `ManagedKey` as an independent cryptographic entity: + +```go +// From thresholdvm/vm.go +type ManagedKey struct { + KeyID string // "eth-usdc", "lux-btc", etc. + Threshold int // t value for THIS key + TotalParties int // n value for THIS key + PartyIDs []party.ID // Signers for THIS key + Algorithm MPCAlgo // CGG21, MuSig2, FROST, Ringtail + CreatedAt uint64 // Block height + LastRotation uint64 // Last key refresh height + Metadata KeyMetadata // Extended attributes +} +``` + +Example configurations demonstrating flexibility: + +| KeyID | Threshold | Parties | Use Case | +|-------|-----------|---------|----------| +| `lux-usdc` | 2-of-3 | 3 | Fast, frequent small transfers | +| `eth-btc` | 4-of-7 | 7 | High-value BTC custody | +| `zoo-nft` | 3-of-5 | 5 | Balanced NFT bridge | +| `eth-usdc-large` | 5-of-9 | 9 | Large USDC (>$100K) transfers | +| `btc-native` | 5-of-9 | 9 | Native BTC via Taproot MuSig2 | + +### Benefits + +1. **Risk-Based Security**: Higher-value assets receive proportionally stronger protection through increased thresholds and larger signer committees. + +2. **Performance Optimization**: Low-value, high-frequency transfers complete faster with reduced thresholds, improving user experience without compromising security for the value at stake. + +3. **Flexible Governance**: Different asset classes can have distinct governance models, compliance structures, and operational procedures appropriate to their specific requirements. + +4. **Isolated Compromise**: Compromising one key's signer set does not affect other keys. An attacker who compromises signers for `eth-usdc` cannot sign for `btc-native` unless those signers overlap and meet the threshold for both. + +5. **Regulatory Compliance**: Certain jurisdictions or asset types may require specific custody arrangements. Per-asset keys enable compliance with diverse regulatory frameworks. + +6. **Operational Efficiency**: Signer hardware and availability requirements can be tailored per asset, reducing infrastructure costs for lower-risk assets. + +## Specification + +### 1.

Compromise of shares for one key reveals nothing about other keys. + +2. **Signer Set Separation**: Even when signers overlap between keys, the threshold requirement is evaluated independently. An attacker controlling t-1 signers for Key A and t-1 signers for Key B cannot combine knowledge to forge signatures for either key. + +3. **Value Compartmentalization**: Maximum custody value per key can be enforced, limiting exposure from any single key compromise. + +### Compromise Scenarios + +| Scenario | Impact | Mitigation | +|----------|--------|------------| +| Single signer compromised | None (t-1 shares insufficient) | Detect via anomaly, rotate | +| t-1 signers compromised | None (threshold not met) | High alert, emergency rotation | +| t signers compromised | Single key funds at risk | Other keys unaffected; value limits cap loss | +| Algorithm break (ECDSA) | Keys using that algorithm at risk | Migrate to PQ algorithms; dual-sig mode | +| Key metadata leaked | Operational intelligence exposed | Metadata is mostly public; shares remain secure | + +### Attack Surface Minimization + +```go +// Access control for key operations +type Permission uint8 + +const ( + PermNone Permission = iota + PermRead // View key metadata + PermSign // Request signatures + PermOperate // Manage signers + PermGovernance // Create/revoke keys +) + +type ACL struct { + KeyID string + Permissions map[ids.ShortID]Permission +} + +func (vm *VM) CheckPermission(caller ids.ShortID, keyID string, required Permission) error { + acl := vm.state.GetACL(keyID) + if acl.Permissions[caller] < required { + return fmt.Errorf("insufficient permission: have %v, need %v", + acl.Permissions[caller], required) + } + return nil +} +``` + +### Quantum Security + +Keys may be configured for hybrid classical/quantum security: + +```go +type QuantumConfig struct { + Enabled bool // Dual-signature mode + ClassicalAlgo MPCAlgo // CGG21, MuSig2, FROST + QuantumAlgo MPCAlgo // Ringtail (lattice-based) + ClassicalThresh uint8 + QuantumThresh uint8 +} + +// Dual signature verification +func VerifyDualSignature(msg []byte, classical, quantum []byte, config QuantumConfig) error { + if err := VerifyClassical(msg, classical, config.ClassicalAlgo); err != nil { + return fmt.Errorf("classical signature invalid: %w", err) + } + if config.Enabled { + if err := VerifyQuantum(msg, quantum, config.QuantumAlgo); err != nil { + return fmt.Errorf("quantum signature invalid: %w", err) + } + } + return nil +} +``` + +## Backwards Compatibility + +This LP is additive to existing T-Chain and T-Chain functionality: + +1. **Existing Keys**: Keys created before this specification continue to function. They are implicitly assigned `KeyID` based on their asset and default metadata. + +2. **Legacy RPC**: Existing RPC methods (`mchain.swapSig.*`) remain operational. New methods are additive. + +3. **Transaction Formats**: New transaction types (`KeyCreateTx`, `KeyRotateTx`, etc.) use unused type IDs. Existing transaction processing is unchanged. + +4. **Signer Software**: Existing `mpckeyd` instances can be upgraded incrementally. The protocol negotiates capabilities during DKG. + +## Rationale + +### Design Decisions + +1. **Per-Asset Isolation**: Each managed key operates independently with its own threshold (t), total party count (n), and signer set. This provides cryptographic isolation where compromise of one key does not affect others, enabling risk-appropriate security configurations per asset. + +2. **Value-Based Tiering**: Threshold and party count scale with asset value to balance security requirements against operational efficiency. High-value assets receive proportionally stronger protection (higher thresholds, larger committees) while low-value assets optimize for speed. + +3. **Hierarchical Key Naming**: The `{chain}-{asset}[-{variant}]` naming convention provides uniqueness, discoverability, and extensibility. New chains and assets can be added without conflicts while maintaining clear operational semantics. + +4. **Geographic Diversity**: Signer distribution across multiple jurisdictions ensures resilience against regional failures, regulatory actions, and coordinated attacks. Higher-value tiers require more geographic diversity. + +5. **Algorithm Flexibility**: Supporting multiple MPC algorithms (CGG21, MuSig2, FROST, Ringtail) enables native compatibility with different blockchain curves and provides a quantum-safe migration path. + +6. **Proactive Key Refresh**: Time-based share regeneration without changing public keys provides forward security while maintaining operational continuity. Refresh intervals scale inversely with asset value. + +## Test Cases + +### Key Creation Tests + +```go +func TestKeyCreation_ValidConfig(t *testing.T) { + vm := setupTestVM() + + tx := &KeyCreateTx{

+### TypeScript SDK + +The library is exposed via TypeScript SDK at `@luxfi/threshold` (see LP-7341). + +## Rationale + +### Multi-Protocol Support + +Supporting multiple threshold protocols addresses different use cases: + +1. **LSS**: Best for general-purpose use with fast keygen +2. **CMP (CGGMP21)**: UC-secure with identifiable abort for high-security applications +3. **FROST**: Optimal for Schnorr-based chains (Bitcoin Taproot) +4. **Doerner**: Efficient 2-party ECDSA for simpler deployments +5. **Ringtail**: Post-quantum threshold signatures for future-proofing + +### Modular Architecture + +The modular design provides: + +1. **Isolation**: Protocol bugs don't affect other implementations +2. **Testing**: Each protocol tested independently +3. **Upgrades**: New protocols can be added without changing existing code +4. **Selection**: Applications choose optimal protocol for their needs + +### Worker Pool Design + +Using a shared worker pool enables: + +1. **Resource Control**: Limit concurrent cryptographic operations +2. **Parallelism**: Maximize CPU utilization for expensive operations +3. **Fairness**: Prevent single operation from monopolizing resources + +## Backwards Compatibility + +### API Stability + +The library maintains backwards compatibility through: + +- Stable `protocol.StartFunc` interface +- Versioned config structures +- Additive-only changes to public APIs + +### Protocol Version Support + +- All protocols support version negotiation +- Older key shares work with newer library versions +- Explicit migration paths when breaking changes required + +### Integration Compatibility + +Works seamlessly with: + +- ThresholdVM (T-Chain) - primary integration +- BridgeVM (B-Chain) - cross-chain signing +- External applications via standard interfaces + +## Test Cases + +### Protocol Tests + +```go +func TestLSSKeygenSign(t *testing.T) { + // Setup 3-of-5 threshold + parties := generatePartyIDs(5) + threshold := 3 + + // Run

Considerations + +1. **Memory Safety**: Shares are zeroed after use where possible +2. **Side Channels**: Constant-time operations for sensitive computations +3. **Randomness**: Uses cryptographically

This tier provides maximum security for the most sensitive workloads. - -2. **Tier 2 (Confidential VM)**: AMD, Intel, and Arm all offer CPU-level CC. Combined with GPU passthrough, this provides strong isolation without requiring specialized GPU hardware. - -3. **Tier 3 (Device TEE)**: Mobile and edge devices have integrated TEEs with AI accelerators. This tier enables the vast ecosystem of edge AI devices. - -### Why Not Include DGX Spark (GB10)? - -NVIDIA DGX Spark (GB10) uses the Grace SoC without NVTrust support for the AI components. It's classified as Tier 4 (Standard) because: -- No hardware CC for GPU memory -- Software attestation only -- Suitable for non-sensitive workloads - -### Trust Score Design - -The trust score calculation balances: -- **Hardware (40%)**: Incentivizes CC hardware adoption -- **Attestation (30%)**: Rewards fresh attestations -- **Reputation (20%)**: Values historical reliability -- **Uptime (10%)**: Ensures availability - -This weighting ensures that hardware CC tier is the primary differentiator while still rewarding good behavior. - -## Backwards Compatibility - -This LP extends LP-2001 (AIVM) with CC tier awareness: - -- Existing providers default to Tier 4 (Standard) -- Tasks without `minCCTier` field are matched to any tier -- Trust scores are backwards compatible with existing `TrustScore` field -- No breaking changes to existing AIVM API -

-## Security Considerations - -### Attestation Freshness - -- Attestations must be refreshed regularly (recommended: every 1 hour for Tier 1, 24 hours for Tier 2/3) -- Stale attestations result in trust score degradation -- Providers with expired attestations are demoted to Tier 4 - -### Fake Attestation Prevention - -- All attestation quotes verified against manufacturer root certificates -- Certificate chains validated to hardware manufacturer roots (NVIDIA, AMD, Intel, Arm, Apple, Qualcomm) -- Replay prevention via challenge-response nonces - -### Side-Channel Attacks - -- Tier 1 provides strongest protection (hardware-level) -- Tier 2 protects CPU operations but GPU may be vulnerable -- Tier 3 varies by device (Apple Secure Enclave is strong, others vary) -- Tier 4 provides no hardware protection - -### Physical Attacks - -- Tier 1 and 2 protect against software attacks on host -- Tier 3 provides tamper-evident storage -- Physical access to hardware may compromise all tiers -- Critical workloads should use multiple independent providers - -## Economic Impact - -### Provider Incentives - -Higher CC tiers command premium fees: -- Tier 1 providers earn 1.5x base rewards -- Investment in CC-capable hardware justified by increased earnings -- Network effect: more Tier 1 providers attract more premium workloads - -### Network Security - -- Default tasks matched to appropriate tier based on sensitivity -- Premium fees fund CC hardware investment -- Slashing for attestation fraud deters cheating - -## Related Proposals -

The system enables permissionless sequencer participation with economic incentives, supports multiple sequencer selection strategies including round-robin, weighted random, and auction-based models, and provides specialized mechanisms for AI workload scheduling and distributed training coordination. The protocol ensures liveness, censorship resistance, and fair transaction ordering through cryptographic commitments and threshold decryption. + +## Activation + +| Parameter | Value | +|--------------------|--------------------------| +| Flag string | `lp504-sequencer-registry` | +| Default in code | **false** until block X | +| Deployment branch | `v0.0.0-lp504` | +| Roll‑out criteria | 10+ active sequencers | +| Back‑off plan | Fallback to L1 sequencing | + +## Motivation + +Centralized sequencers present critical risks: + +1. **Single Point of Failure**: Downtime affects entire L2 +2. **Censorship Risk**: Can exclude transactions arbitrarily +3. **MEV Extraction**: Unfair value extraction from users +4. **Trust Requirements**: Users must trust sequencer operator +5. **Limited Scalability**: Single sequencer bottlenecks throughput + +Decentralized sequencing enables: +- **Liveness Guarantees**: Multiple sequencers ensure availability +- **Censorship Resistance**: Transactions eventually included +- **Fair Ordering**: Cryptographic mechanisms prevent manipulation +- **Horizontal Scaling**: Multiple sequencers increase throughput +- **Specialized Scheduling**: AI workloads get appropriate resources + +## Specification + +### Core Registry Interface + +```solidity +interface ISequencerRegistry { + enum SequencerStatus { + Inactive, + Active, + Suspended, + Ejected, + Exiting + } + + enum SelectionMode { + RoundRobin, + WeightedRandom, + Auction, + Performance, + Hybrid + } + + struct SequencerInfo { + address operator;

The format supports multiple transaction types including standard transfers, smart contract calls, AI inference requests, and distributed training updates. It implements advanced compression techniques achieving 10-20x reduction in data size, batch aggregation for efficient L1 settlement, and cryptographic commitments for state integrity. The specification includes extensions for cross-rollup communication and quantum-resistant signatures. + +## Activation + +| Parameter | Value | +|--------------------|--------------------------| +| Flag string | `lp505-l2-block-format` | +| Default in code | **false** until block X | +| Deployment branch | `v0.0.0-lp505` | +| Roll‑out criteria | 1M blocks produced | +| Back‑off plan | Legacy format support | + +## Motivation + +Current L2 block formats lack: + +1. **Compression Optimization**: Inefficient data encoding +2. **AI Metadata**: No support for compute workload tracking +3. **Batch Efficiency**: Poor aggregation for L1 submission +4. **Cross-rollup Standards**: Incompatible formats between L2s +5. **Future-proofing**: No quantum-resistant signature support + +This specification provides: +- **90% Size Reduction**: Advanced compression techniques +- **AI-Native Support**: Built-in compute metadata fields +- **Efficient Aggregation**: Optimized for batch submission +- **Interoperability**: Standard format across rollups +- **Quantum Resistance**: Support for post-quantum signatures + +## Specification + +### Core Block Structure + +```solidity +interface IL2BlockFormat { + struct L2Block { + BlockHeader header;

-#### Create a DAO - -```typescript -import { LuxDAO, VotingStrategyType } from '@luxdao/sdk' - -const dao = await LuxDAO.create({ - name: 'My DAO', - owners: ['0x...', '0x...', '0x...'], - threshold: 2, - governanceToken: tokenAddress, - votingStrategy: VotingStrategyType.LinearERC20, - timelockPeriod: 86400, // 1 day - quorum: 400 // 4% -}) - -console.log('DAO created:', dao.address) -``` - -#### Create and Vote on Proposal - -```typescript -import { LuxDAO, VoteType } from '@luxdao/sdk' - -const dao = new LuxDAO({ - provider, - signer, - daoAddress: '0x...' -}) - -// Create proposal -const tx = await dao.createProposal({ - title: 'Fund Development', - description: 'Allocate 100 ETH for Q1 development', - transactions: [ - { - to: devMultisig, - value: ethers.utils.parseEther('100'), - data: '0x', - operation: 0 - } - ] -}) - -const receipt = await tx.wait() -const proposalId = getProposalIdFromReceipt(receipt) - -// Vote -await dao.vote(proposalId, VoteType.For) - -// Check status -const proposal = await dao.getProposal(proposalId) -console.log('State:', proposal.state) -console.log('For votes:', proposal.forVotes.toString()) -``` - -#### Delegate Voting Power - -```typescript -// Delegate to another address -await dao.delegate('0xDelegatee...') - -// Check voting power -const power = await dao.getVotingPower(myAddress) -console.log('Voting power:', ethers.utils.formatEther(power)) -``` - -#### Emergency Freeze - -```typescript -const freezeGuard = dao.freezeGuard - -// Check if frozen -const isFrozen = await freezeGuard.isFrozen() - -// Cast freeze vote -await freezeGuard.castFreezeVote() - -// Check vote count -const voteCount = await freezeGuard.getFreezeProposalVoteCount() -const threshold = await freezeGuard.getFreezeVotesThreshold() - -console.log(`Freeze votes: ${voteCount}/${threshold}`) -``` - -### Testing - -```bash -cd dao/sdk -pnpm test - -# Output: -# ✓ LuxDAO initializes correctly -# ✓ createProposal submits proposal -# ✓ vote casts vote correctly -# ✓ getProposal returns proposal data -# ✓ delegate updates delegation -# ✓ executeProposal executes when ready -# ✓ FreezeGuard tracks freeze state -# ✓ Contract factories export correctly -``` - -## Rationale - -### TypeScript-First Design - -Choosing TypeScript provides: - -1. **Type Safety**: Catch errors at compile time -2. **Developer Experience**: IntelliSense and autocomplete -3. **Documentation**: Types serve as inline documentation -4. **Ecosystem**: Wide adoption in web3 development - -### Class-Based Architecture - -Using classes for main components provides: - -1. **Encapsulation**: Internal state management -2. **Composition**: Combine multiple contract interactions -3. **Extensibility**: Easy to subclass for custom behavior - -### Factory Exports - -Exporting contract factories enables: - -1. **Direct Access**: Low-level contract interaction when needed -2. **Deployment**: Deploy new contract instances -3. **Custom Integration**: Build specialized tooling - -## Backwards Compatibility - -### ethers.js Compatibility - -The SDK is built on ethers.js v6: - -- Uses standard Provider and Signer interfaces -- Compatible with ethers.js utilities -- Works with any ethers.js-compatible wallet - -### Web3 Provider Compatibility - -Works with standard Web3 providers: - -- MetaMask and injected providers -- WalletConnect -- Ledger and hardware wallets -- Any EIP-1193 provider - -### Contract Version Support - -Supports all Lux DAO contract versions: - -- V1 contracts (current) -- Automatic version detection -- Graceful handling of missing features - -## Test Cases - -### SDK Tests - -```typescript -describe('LuxDAO', () => { - it('initializes with valid address', async () => { - const dao = new LuxDAO({ provider, daoAddress }); - expect(dao.address).toBe(daoAddress); - }); - - it('fetches DAO name', async () => { - const name = await dao.getName(); -

This LP establishes the master framework governing how Environmental integrity, Social benefit, and Governance accountability are defined, measured, and enforced across all investments. Returns and restoration reinforce each other—by design, not by accident. - -## Motivation - -Traditional investment frameworks treat ESG as an optional overlay or marketing exercise. This creates misaligned incentives where capital optimizes for short-term returns at the expense of environmental and social outcomes. Lux Vision Fund requires a foundational framework that: - -1. **Structurally integrates ESG** - Making impact measurement and accountability core to investment terms, not optional addenda -2. **Prevents greenwashing** - Requiring verifiable, measurable outcomes before any public claims -3. **Aligns long-term incentives** - Using tranched capital deployment tied to verified milestones -4. **Enables transparent reporting** - Building trust with LPs, regulators, and the public through auditable evidence -5. **Coordinates ecosystem actors** - Defining clear roles for Lux (capital), Hanzo (technology), Zoo (mission), and DAOs (governance) - -Without this framework, ESG investments risk becoming performative rather than substantive, undermining both returns and restoration goals. - -## Core Values (Non-Negotiables) - -### 1. Everyone Benefits, Not Just Capital - -We design investments so value accrues to communities, contributors, customers, and the environment—alongside LP returns. This is structural, not aspirational. - -### 2. Proof Over Promises - -Impact claims are only valid if they're **measurable**, **attributable**, and **auditable**. If we can't measure it, we don't market it. - -### 3. Long-Term Ownership and Compounding - -Community governance and IP stewardship ensure long-tail value doesn't get extracted and disappear. DAOs retain ownership so contributors capture value from what they help build. - -## ESG Pillars Summary - -| Pillar | Principle | Core Question | -|--------|-----------|---------------| -| **E - Environmental** | Measurable improvement, not vibes | Does this reduce net harm or create net-positive restoration vs. baseline? | -| **S - Social** | Opportunity, dignity, and resilience | Does this create real economic mobility and protect against exploitation? | -| **G - Governance** | Accountability through architecture | Is this auditable, privacy-preserving, and community-governed? | - -## The Lux–Hanzo–Zoo Ecosystem - -### Role Architecture - -| Entity | Layer | Function | -|--------|-------|----------| -| **Lux** | Finance | Forms and deploys capital, builds settlement and reporting rails, hard-codes accountability into funding terms | -| **Hanzo** | Creation | Incubates and deploys frontier tech (AI/robotics/quantum) with efficiency, safety, and privacy-first architecture | -| **Zoo** | Mission | Anchors public benefit across all life, sets ethical boundaries, ensures programs remain restorative and non-extractive | -| **DAOs** | Ownership | Steward IP and governance so communities capture long-tail value from what they help build | - -### The Flywheel of Good - -```solidity -┌─────────────────────────────────────────────────────────────────┐ -│ │ -│ 1.

Environmental integrity is measured against baselines and verified over time; social benefit is defined by economic mobility, access, and resilience; and governance is enforced through on-chain auditability with privacy-preserving controls. Lux provides capital and financial rails, Hanzo builds and verifies high-impact technology, Zoo anchors life-first mission and ethics, and our DAOs steward community ownership of IP so long-tail value accrues to contributors and communities. The result is a thoughtfully designed flywheel where transparency builds trust, trust attracts capital, and capital scales verified outcomes. - -## Specification - -This LP serves as a meta-framework defining investment policies. The specification is embodied in: - -1. **Core Values** (Section above) - Non-negotiable principles -2. **ESG Pillars** - Environmental, Social, and Governance definitions -3. **Investment Process** - Five-stage workflow from intake to scale -4. **Enforcement Mechanisms** - Outcome-gated capital, claims registry, verification - -Detailed specifications for each pillar are defined in subsidiary LPs (LP-751, LP-752, LP-753). - -## Rationale - -The framework design reflects several key decisions: - -1. **Tranched capital over lump-sum** - Reduces risk of misuse and creates accountability checkpoints -2. **Claims registry with evidence hashes** - Enables third-party verification without exposing sensitive data -3. **Privacy-preserving verification** - Balances transparency with data protection using ZK proofs -4. **Ecosystem role separation** - Clear boundaries prevent conflicts of interest and enable specialization -5. **Binding covenants over voluntary guidelines** - Legal enforcement mechanisms complement on-chain accountability - -## Backwards Compatibility - -This LP establishes a new framework and does not modify existing investment structures. Existing investments may be evaluated against this framework but are not retroactively bound by it. - -## Security Considerations - -1. **Evidence tampering** - Mitigated through immutable on-chain hashes and third-party attestations -2. **Verifier collusion** - Multiple independent verifiers required for material claims -3. **Privacy leakage** - ZK proofs and aggregated statistics prevent individual data exposure -4. **Governance capture** - DAO voting mechanisms include anti-concentration measures - -## Test Cases - -As a Meta LP, formal test cases are not applicable. Framework validation is demonstrated through: - -1. Successful application to pilot investments -2. Third-party audit of claims registry integrity -3. LP and stakeholder satisfaction surveys -4.

As the finance layer of the Lux-Hanzo-Zoo ecosystem, we deploy capital only to ESG-aligned opportunities, with environmental integrity measured against baselines, social benefit defined by economic mobility and resilience, and governance enforced through on-chain accountability. Our infrastructure enables low-cost, transparent financial access globally, while our investment vehicles hard-code impact covenants into funding terms. The result is a flywheel where proof builds trust, trust attracts capital, and capital scales verified outcomes—creating a compounding system where everyone benefits, not just capital. - -## Changelog - -| Version | Date | Changes | -|---------|------|---------| -| 1.0 | 2025-12-17 | Initial draft | - diff --git a/LPs/lp-8920-esg-principles-and-commitments.md b/LPs/lp-8920-esg-principles-and-commitments.md deleted file mode 100644 index d30c72d7..00000000 --- a/LPs/lp-8920-esg-principles-and-commitments.md +++ /dev/null @@ -1,196 +0,0 @@ ---- -lp: 8920 -title: ESG Principles and Commitments -tags: [esg, sustainability] -description: Foundational ESG framework defining Lux Network's environmental, social, and governance commitments. -author: Lux Network Team (@luxfi) -discussions-to: https://github.com/luxfi/lps/discussions -status: Draft -type: Meta -created: 2025-12-16 -order: 2920 ---- - -# LP-800: ESG Principles and Commitments - -## Abstract - -This LP establishes the foundational Environmental, Social, and Governance (ESG) framework for Lux Network.

This creates a direct 1:1 mapping between LP documentation numbers and precompile addresses. +LP-9015 specifies the PrecompileRegistry, a central registry and helper library for all Lux EVM precompiles. The registry maps addresses in the `0x0200...00XX` range to named precompiles covering core network functions, post-quantum cryptography, threshold signatures, and DeFi primitives. ## Motivation -### Direct LP Alignment +### Precompile Discovery -The trailing LP format is maximally simple: -- **LP-9010** (LXPool) → `0x0000000000000000000000000000000000009010` -- **LP-9011** (LXOracle) → `0x0000000000000000000000000000000000009011` -- **LP-6010** (Teleport) → `0x0000000000000000000000000000000000006010` +Applications need to: +1. **Discover** available precompiles +2. **Verify** precompile availability +3. **Categorize** precompiles by function +4. **Track** address changes across upgrades -No calculations needed. The LP number IS the address suffix. +### Registry Benefits -### LX Naming Convention +1. **Single Source of Truth**: One location for all addresses +2. **Type Safety**: Named constants prevent address errors +3. **Upgradability**: Central location for address updates +4. **Discovery**: Runtime precompile availability checks -**LX** is the umbrella name for the Lux DEX stack (AMM + CLOB + vaults + feeds + routing). -Individual precompiles use the **LX prefix** for developer-facing clarity: +## Specification -| Human Name | Technical Name | Purpose | -|------------|---------------|---------| -| LX | (umbrella) | The whole on-chain trading system | -| LXPool | LP-9010 | v4 PoolManager-compatible AMM core | -| LXOracle | LP-9011 | Multi-source price aggregation | -| LXRouter | LP-9012 | Optimized swap routing | -| LXHooks | LP-9013 | Hook contract registry | -| LXFlash | LP-9014 | Flash loan facility | -| LXBook | LP-9020 | Permissionless orderbooks + matching + advanced orders | -| LXVault | LP-9030 | Balances, margin, collateral, liquidations | -| LXFeed | LP-9040 | Price feed aggregator | +### Address Range -### Benefits +All Lux precompiles use the address range: +``` +0x0200000000000000000000000000000000000001 to +0x0200000000000000000000000000000000000FFF +``` -1. **Zero Ambiguity**: LP number directly visible in address -2. **Easy Discovery**: Looking at address immediately tells you the LP -3. **Multi-Chain Consistent**: Same address on all EVM chains (C-Chain, Zoo, Hanzo, SPC) -4. **Maximum Simplicity**: No encoding scheme to learn or compute +### Registry Contract -## Specification +```solidity +// SPDX-License-Identifier: BSD-3-Clause +// Copyright (c) 2025 Lux Industries Inc. +pragma solidity ^0.8.24; -### Address Format +/// @title PrecompileRegistry +/// @notice Central registry of all Lux DeFi precompile addresses +/// @dev All precompiles are in the 0x0200...00XX address range +library PrecompileRegistry { + /*////////////////////////////////////////////////////////////// + CORE PRECOMPILES + //////////////////////////////////////////////////////////////*/ -``` -Address = 0x0000000000000000000000000000000000LPNUM + /// @notice Deployer allow list management + address internal constant DEPLOYER_ALLOW_LIST = 0x0200000000000000000000000000000000000001; -Where: -

-} -``` - -## Rationale - -### Single Execute Endpoint vs Many Functions - -The `execute()` pattern provides: -1. **Minimal ABI**: One function signature for all trading operations -2. **Typed Payloads**: Strong typing via ABI encoding/decoding -3. **Batch Atomicity**: Multiple actions in one transaction -4. **Extensibility**: New action types without ABI changes - -### TP/SL Without Tight Coupling - -TP/SL orders that "attach to position" and auto-resize are NOT in LXBook because they require reading positions from LXVault, creating tight coupling. - -Instead: -- **SDK/UI**: Track positions client-side, place/cancel triggers accordingly -- **Helper Contract**: Small contract that reads LXVault positions and manages reduce-only triggers - -This keeps LXBook as a pure matching engine. - -### Uniswap v4 Compatibility - -LXPool implements `IPoolManager` exactly. LXBook is a separate CLOB primitive. - -SDK exports both: -```typescript -export const LX_POOL = '0x...9010' -export const POOL_MANAGER = LX_POOL // v4 compat alias -``` - -## Backwards Compatibility - -This specification introduces new functionality and does not modify existing protocols. It is fully backwards compatible with existing implementations. - -## Security Considerations - -### Anti-Replay - -Actions include `nonce` and `expiresAfter`: -- `nonce`: Recommended as ms timestamp or monotonic counter -- `expiresAfter`: Unix seconds; action rejected if `block.timestamp > expiresAfter` - -### Order Validation - -All orders must: -- Reference a valid, active market -- Have size ≥ lotSize -- Have price aligned to tickSize (for limit orders) -- Satisfy reduce-only constraints (if set) - -### Rate Limiting - -`RESERVE_WEIGHT` action allows buying extra action credits. Implementations MAY enforce per-address rate limits. - -## Test Cases - -```solidity -function testPlaceLimitOrder() public { - ILXBook.Order[] memory orders = new ILXBook.Order[](1); - orders[0] = ILXBook.Order({ - marketId: ethUsdcMarket, - isBuy: true, - kind: ILXBook.OrderKind.LIMIT, - sizeX18: 1e18, // 1 ETH - limitPxX18: 2000e18, // $2000 - triggerPxX18: 0, - reduceOnly: false, - tif: ILXBook.TIF.GTC, - cloid: keccak256("order-1"), - groupId: bytes32(0), - groupType: ILXBook.GroupType.NONE - }); - - ILXBook.Action memory action = ILXBook.Action({ - actionType: ILXBook.ActionType.PLACE, - nonce: uint64(block.timestamp * 1000), - expiresAfter: 0, - data: abi.encode(orders) - }); - - bytes memory result = lxbook.execute(action); - ILXBook.PlaceResult[] memory results = abi.decode(result, (ILXBook.PlaceResult[])); - - assertEq(results[0].status, 2); // resting on book -} - -function testOCOGroup() public { - bytes32 groupId = keccak256("oco-group-1"); - - ILXBook.Order[] memory orders = new ILXBook.Order[](2); - - // Take profit at $2500 - orders[0] = ILXBook.Order({ - marketId: ethUsdcMarket, - isBuy: false, - kind: ILXBook.OrderKind.TAKE_LIMIT, - sizeX18: 1e18, - limitPxX18: 2500e18, - triggerPxX18: 2500e18, - reduceOnly: true, - tif: ILXBook.TIF.GTC, - cloid: keccak256("tp"), - groupId: groupId, - groupType: ILXBook.GroupType.OCO - }); - - // Stop loss at $1800 - orders[1] = ILXBook.Order({ - marketId: ethUsdcMarket, - isBuy: false, - kind: ILXBook.OrderKind.STOP_MARKET, - sizeX18: 1e18, - limitPxX18: 0, - triggerPxX18: 1800e18, - reduceOnly: true, - tif: ILXBook.TIF.IOC, - cloid: keccak256("sl"), - groupId: groupId, - groupType: ILXBook.GroupType.OCO - }); - - // When TP fills, SL auto-cancels (and vice versa) -} -``` - -## Related LPs - -- **LP-9010**: LXPool - v4 PoolManager-Compatible AMM Core -- **LP-9015**: Precompile Registry - LP-Aligned Address Scheme -- **LP-9030**: LXVault - Balances, Margin, Collateral, Liquidations - -## Copyright - -Copyright and related rights waived via [CC0](https://creativecommons.org/publicdomain/zero/1.0/). diff --git a/LPs/lp-9020-performance-benchmarks.md b/LPs/lp-9020-performance-benchmarks.md new file mode 100644 index 00000000..40ed2cbd --- /dev/null +++ b/LPs/lp-9020-performance-benchmarks.md @@ -0,0 +1,445 @@ +--- +lp: 9020 +title: Performance Benchmarks & Stress Testing +description: Performance requirements, benchmarks, and stress testing standards for production DeFi +author: Lux Core Team +status: Draft +tags: [dex, trading] +type: Standards Track +category: Core +created: 2025-01-15 +requires: [9010, 9014, 9016] +order: 20 +--- + +# LP-9020: Performance Benchmarks & Stress Testing + +## Abstract + +This LP defines performance requirements, benchmarking standards, and stress testing methodologies for Lux DeFi infrastructure.

ecosystem chains, supporting ICS-20 token transfers and ICS-27 interchain accounts. + +2. **MPC Bridge**: A Multi-Party Computation bridge using 2-of-3 threshold signatures for secure cross-chain transfers across 15+ EVM-compatible and non-EVM chains. + +Together, these components enable Lux to serve as a universal interoperability hub, connecting the Cosmos ecosystem via IBC and the broader

This compiles and pkg/policy 37/37 +tests pass with `replace github.com/luxfi/threshold => ../threshold` +in `mpc/go.mod`. + +The `luxfi/threshold/protocols/tfhe` directory is uncommitted at HEAD +of luxfi/threshold (`main` branch).

-### LRC Numbering -- LRCs use the same file naming as LPs: `lp-N.md` -- The LRC number is assigned separately (e.g., LP-20 defines LRC-20) -- Title should include both: "LP-20: LRC-20 Fungible Token Standard" -

Prefer using reflect mode to generate mocks than source mode, unless you need a mock for an unexported interface, which should be rare. -- To **remove** an interface from having a corresponding mock generated: - 1. Edit the `mocks_generate_test.go` file in the directory where the interface is defined - 1. If the `//go:generate` mockgen command line: - - generates a mock file for multiple interfaces, remove your interface from the line - - generates a mock file only for the interface, remove the entire line.

Construct subgraph query by making sure that `timestamp_lte` parameter corresponds to the price request timestamp, e.g.: - ``` - { - kpis(first: 1, orderBy: timestamp, orderDirection: desc, where: {timestamp_lte: 1643644800}) { - id - totalTVL - marketCap - holders - transactions - score - timestamp - } - } - ``` -2. Perform `POST` request on the `Endpoint` (passed as a parameter from ancillary data) with request body from Step 1. As an illustration, `curl` request would look like: - ``` - curl -X POST \ - -d '{"query": "{kpis(first: 1, orderBy: timestamp, orderDirection: desc, where: {timestamp_lte: 1643644800}) {id, totalTVL, marketCap, holders, transactions, score, timestamp}}"}' \ - 'https://api.thegraph.com/subgraphs/name/gwydce/mumbai-pi' - ``` -3. Take a note on the combined KPI score metric from the returned subgraph response value corresponding to `Key` parameter from ancillary data. -4. At the time of authorship of this document the subgraph is configured to truncate the score down to 6 decimals. In case it is modified for greater precision voters should still truncate it to 6 decimals before returning it as resolved price request. - -The voters should also verify that the combined KPI score is returned correctly based on the values of individual KPI components as returned by the subgraph. The values of each component target and weight should be set by parsing the JSON object passed as the `Score` parameter in the ancillary data. Actual values might change across different KPI option tranches, but as an illustration, the `Score` parameter in the Intended Ancillary Data section above would be interpreted as: - -| Key | Interpretation | Target | Weight | -|--------------|-----------------------------------------------------------|--------|--------| -| totalTVL | TVL for all 2Pi products | $10MM | 40% | -| marketCap | Fully diluted market capitalization of 2Pi token | $15MM | 40% | -| holders | Number of users holding 2Pi and stk2Pi tokens | 2,000 | 10% | -| transactions | Number of Deposit+Withdrawal transactions in 2Pi products | 5,000 | 10% | - -The value of each individual KPI component should be divided by its target multiplied by its weight. Each component should be capped at its maximum weight value so that the resulting score calculated as the sum of individual components is between 0 and 1. - -## Fallback implementation - -In case of technical issues with subgraph, suspected manipulation or when its not being synchronized for longer than 24 hours before the request timestamp voters should attempt to resolve the request by querying individual KPI components on-chain and aggregating the score based on the logic behind subgraph [source code implementation](https://github.com/2pinetwork/subgraphs). - -Voters should take a note on the canonical list of 2Pi project contracts in the [documentation](https://docs.2pi.network/) once they are deployed on Polygon mainnet. - -Note that the 2Pi is evolving project and at the time of price request it could have additional products that are not explicitly covered by the fallback methodology outlined below. In any case voters should watch for any 2Pi project updates and amendments in subgraph [source code](https://github.com/2pinetwork/subgraphs) and consider them as long as they align with the general spirit of this aggregated KPI metrics score calculation. Though the general score components, target values and their weights should be immutable over the life time of deployed KPI options. - -### TVL - -TVL covers 2Pi tokens held by the stk2Pi staking contract and tokens staked through Archimedes staking contract. - -Amount of 2Pi tokens in the stk2Pi staking contract can be fetched by calling `balanceOf` method on 2Pi contract with stk2Pi address in the argument at the latest available block at or before the request timestamp. The result should be scaled down to 18 decimals. - -In order to determine tokens staked through Archimedes one should first call `poolLength` method on the Archimedes staking contract to get number of pools available. Raw amount staked can be fetched by calling `balance` method (iterating through all pools starting from 0) on the Archimedes staking contract at the latest available block at or before the request timestamp. Pool tokens are identified by calling `poolInfo` method with pool index as argument and the first returned field is token address. Amount of tokens staked should be scaled down by each token's decimal count (calling `decimals` method on the token contract). - -In order to determine USD price per staked token voters should follow the calculation logic in subgraph [source code](https://github.com/2pinetwork/subgraphs), but should check if that is consistent with broad market consensus at the price request timestamp. The obtained USD price for each token should be multiplied with amounts staked (both 2Pi in stk2Pi and tokens staked through Archimedes) and aggregated to get TVL in USD. - -### Market capitalization - -Fully diluted market capitalization should be obtained by multiplying 2Pi token price in USD (see TVL section above) with maximum amount of token supply. Maximum amount of token supply is fetched calling `MAX_SUPPLY` or `cap` method on 2Pi contract at the latest available block at or before the request timestamp and scaled down to 18 decimals. - -### Number of users - -Voters should count number of unique account addresses holding either 2Pi or stk2Pi tokens with balance above 0 (except for zero address, 2Pi contract itself, Distributor (timelock) and Archimedes contracts). This can be achieved by indexing all `Transfer` events on both contracts till the latest available block at or before the request timestamp and recalculating active user balances at the end of the period. - -### Number of transactions - -Voters should count total number of deposit and withdraw transactions by filtering events till the latest available block at or before the request timestamp: -* `Deposit` and `Withdraw` events emitted by the stk2Pi staking contract; -* `Deposit`, `Withdraw` and `EmergencyWithdraw` events emitted by the Archimedes staking contract. - -## Intended Application - -It is intended to deploy the documented KPI options on Polygon chain using [LSP contract](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/financial-templates/long-short-pair/LongShortPair.sol) with `General_KPI` price identifier approved in [UMIP-117](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-117.md).

For each cToken contract address returned in step 2, call `underlying` on the cToken contract address to determine the underlying token address. Since ETH does not have an underlying asset on Compound, for cETH (0x4ddc2d193948926d02f9b1fe9e1daa0718270ed5) use WETH (0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2) as the underlying token. -4. Get each account underlying token balances by calling `balanceOfUnderlying()` on each of cToken contracts using each of account addresses from step 1 as an argument. -5. Sum the underlying token balances returned in step 4 for each individual cToken. Multiply the total balance for each cToken by the exchange rate of the underlying asset returned in step 3 at the timestamp being used. Each cToken balance should be priced in USD for the same timestamp and the value should use the timestamp that falls earlier but nearest to the price request timestamp. DeFiLlama estimates this by using aggregated CoinGecko prices, but all voters should verify that results agree with broad market consensus. -6. Sum all cToken balances from step 5 which represents the total Compound TVL in USD. - -### Maker TVL - -1. Call `cdpi()` on the bTvlAddress contract (0x60312e01A2ACd1Dac68838C949c1D20C609B20CF). Use the bcdpmanagerAddress contract address (0x3f30c2381CD8B917Dd96EB2f1A4F96D91324BBed) as the argument which returns the number of existing CDPs. -2. Call `cdpTvl()` on the bTvlAddress contract (0x60312e01A2ACd1Dac68838C949c1D20C609B20CF) to return the value of each CDP denominated in ETH: -- For the first argument, use the bcdpmanagerAddress contract address (0x3f30c2381CD8B917Dd96EB2f1A4F96D91324BBed). -- For the second argument, start with 0 and call `cdpTvl()` at an increment of 1 until the parameter is equal to the returned `cdpi()` value in step 1. -- For the third argument, set the ilk parameter to 0x4554482d41000000000000000000000000000000000000000000000000000000 (ETH-A). -3. Each CDP should be priced in ETH for the same timestamp. The value should use the timestamp that falls earlier but nearest to the price request timestamp. DeFiLlama estimates this by using aggregated CoinGecko prices, but all voters should verify that results agree with broad market consensus. -4. Sum all returned values from step 2. This represents the total balance of all CDPs as an ETH balance. Multiply the total balance by the price of ETH at the timestamp being used. - -### Liquity TVL - -1. Call `bamms()` on the bKeeperAddress contract (0xeaE019ef845A4Ffdb8829210De5D30aC6FbB5371) with index passed as argument (starts at 0 until an error is returned). -2. Call `getCompoundedLUSDDeposit()` on the stabilityPoolAddress contract (0x66017D22b0f8556afDd19FC67041899Eb65a21bb) using each returned output from step 1 as an argument. -3. Each pool should be priced in LUSD for the same timestamp. The value should use the timestamp that falls earlier but nearest to the price request timestamp. DeFiLlama estimates this by using aggregated CoinGecko prices, but all voters should verify that results agree with broad market consensus. -4. Sum the total of all returned values from step 2. This represents the total deposits as an LUSD value. - -### Total TVL - -1. Sum the values from step 6 for Compound TVL, step 4 for Maker TVL, and step 4 for Liquity TVL. This represents the TVL value calculated in USD for all assets locked across B.Protocol contracts on Ethereum. -2.

Below steps provide instructions for the case when `AggregationMethod` and `AggregationPeriod` parameters were not provided at the operation level: - -1. Determine daily query timestamp for operation result data: - - If `RequestTimestampOverride` parameter is provided its value should be used as an override for the actual price request timestamp. Though this should always be ignored if the provided `RequestTimestampOverride` value exceeds actual price request timestamp. - - Daily query timestamp should be set to the closest 24:00 UTC timestamp at or before effective request timestamp expressed as numeric Unix timestamp. -2. Inspect `OperationParameters` value to identify its `metricParameters` or `metricParametersArray` element. Only one of these elements should be present depending on the chosen `Operation`. Value of `metricParameters` is single JSON object while value of `metricParametersArray`is an array of JSON objects containing ancillary data parameters for any directly referenced KPI metrics (or other operations) that will be used as operand(s). In addition to provided ancillary data the operand should also inherit those parameters from the dependent operation that were not provided with following exception: - - the `ReturnFrom` parameter in the operand configuration should be set to `rawMetric`. -3. Resolve all the operand implementation(s) considering parameter inheritance rules from Step 2 as if they were separate price request(s). These should resolve to single timestamp / metric pair for each operand. -4. Proceed with instructions on the chosen `Operation` at [supported operations](#supported-operations) section passing `OperationParameters` object where its `metricParameters` element should be replaced with resolved timestamp / metric key-value pair from Step 3 or `metricParametersArray` replaced with an array of resolved timestamp / metric key-value pairs in the same order as their ancillary data parameters were provided in `metricParametersArray`. -5. If due to chained operations the ancillary data at the operation level includes `ReturnFrom` parameter set to `rawMetric` the calculated intermediary operation result from Step 4 should be paired with the daily query timestamp from Step 1 and returned as timestamp / metric key-value pair for the processing on the dependant operation. Otherwise proceed with the next steps in this implementation. -6. If `RawRounding` is provided follow instructions in [UMIP-117](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-117.md) to apply rounding on the raw operation result based on the value of `RawRounding` parameter and use it for further processing. Otherwise proceed with raw metric. -7. If `Scaling` is provided follow instructions in [UMIP-117](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-117.md) to apply scaling on the rounded raw metric based on the value of `Scaling` parameter and use it for further processing. Otherwise proceed with unscaled metric. -8. If `PostProcessingMethod` is provided follow the instructions of the chosen function section from the [supported post-processing functions](https://github.com/UMAprotocol/UMIPs/blob/master/Implementations/post-processing-functions.md) using the metric from Step 7 and post-processing function parameters from `PostProcessingParameters`. Otherwise proceed with metric from Step 7. -8. Follow instructions in [UMIP-117](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-117.md) to apply rounding on the processed metric based on the value of `Rounding` parameter and return the result as resolved price. - -### Operation over time series - -If `AggregationMethod` and `AggregationPeriod` parameters were provided in the ancillary data at the operation level the operation on the operand metrics should be performed at every daily timestamp (24:00 UTC) over the configured time period following instructions below: - -1. Inspect `OperationParameters` value to identify its `metricParameters` or `metricParametersArray` element. Only one of these elements should be present depending on the chosen `Operation`. Value of `metricParameters` is single JSON object while value of `metricParametersArray`is an array of JSON objects containing ancillary data parameters for any directly referenced KPI metrics (or other operations) that will be used as operand(s). In addition to provided ancillary data the operand should also inherit those parameters from the dependent operation that were not provided with following exception: - - `AggregationMethod` and `AggregationPeriod` parameters should always be overridden in operand(s) from the configuration at the operation level; - - the `ReturnFrom` parameter in the operand configuration should be set to `timeSeries`. -2. Resolve all the operand implementation(s) considering parameter inheritance rules from Step 1 as if they were separate price request(s). These should resolve to an array of timestamp / metric pairs targeting the same time period for each operand (though some of data points could be missing depending on data availability). -3. Transform all time series data from Step 2 by rounding up all the timestamps to the end of day UTC except for 24:00 UTC that should be kept unmodified. -4. Transform all time series data from Step 3 to fill in any missing end of day UTC with previous available values for respective time series. -5. In case of multiple operands identify time series with the latest start timestamp and discard all elements from other time series that fall before this timestamp. -6. In case of multiple operands identify time series with the latest end timestamp and fill up missing end of day UTC with previous available values till this timestamp for all the remaining time series. As a result of Steps 5 and 6 all time series should have values for the same set of daily timestamps. -7. Depending on the number of operands: - - In case of single operand for each resolved timestamp from Step 4 proceed with instructions on the chosen `Operation` at [supported operations](#supported-operations) section passing `OperationParameters` object where its `metricParameters` element should be replaced with the processed timestamp / metric key-value pair. - - In case of multiple operands first group their resolved timestamp / metric key-value pairs in arrays for each of obtained timestamps from Step 6 in the same order as their ancillary data parameters were provided in `metricParametersArray`. Then for each resolved timestamp proceed with instructions on the chosen `Operation` at [supported operations](#supported-operations) section passing `OperationParameters` object where its `metricParametersArray` element should be replaced with an array of resolved timestamp / metric key-value pairs for the respective operands. -8. Match all operation results from Step 7 with their operand timestamps (these should match across all operands) to form array of timestamp / result key-value pairs. -9. If due to chained operations the ancillary data at the operation level includes `ReturnFrom` parameter set to `timeSeries` the obtained intermediary time series results from Step 8 should be returned for the processing on the dependant operation. Otherwise proceed with the next steps in this implementation. -10. Follow the instructions of the chosen `AggregationMethod` section from the [supported aggregation methods](https://github.com/UMAprotocol/UMIPs/blob/master/Implementations/aggregation-methods.md) using the operation time series from Step 9 for all the daily timestamps to derive single operation value. -11. If `RawRounding` is provided follow instructions in [UMIP-117](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-117.md) to apply rounding on the raw operation result based on the value of `RawRounding` parameter and use it for further processing. Otherwise proceed with raw metric. -12. If `Scaling` is provided follow instructions in [UMIP-117](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-117.md) to apply scaling on the rounded raw metric based on the value of `Scaling` parameter and use it for further processing. Otherwise proceed with unscaled metric. -13. If `PostProcessingMethod` is provided follow the instructions of the chosen function section from the [supported post-processing functions](https://github.com/UMAprotocol/UMIPs/blob/master/Implementations/post-processing-functions.md) using the metric from Step 12 and post-processing function parameters from `PostProcessingParameters`. Otherwise proceed with metric from Step 12. -14. Follow instructions in [UMIP-117](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-117.md) to apply rounding on the processed metric based on the value of `Rounding` parameter and return the result as resolved price. - -Note that not all `Operation` types support time series data (see details in [supported operations](#supported-operations) section), and when aggregation was requested on unsupported operation due to misconfiguration the verifiers should ignore `AggregationMethod` and `AggregationPeriod` parameters and proceed with instructions in the [Single timestamp operation](#single-timestamp-operation) section above. This should also be used as a fall-back mechanism if operation over time series is impossible to resolve due to missing data. - -## Supported Operations - -Below sections provide instructions where each of section names corresponds to the supported values for the `Operation` parameter values passed in the ancillary data. `OperationParameters` passed in the ancillary data should be a JSON object with key-value pairs representing named function parameters as detailed below. Only one of selected operations should be followed for resolving KPI metric request. - -All the operations require either one of below described members of `OperationParameters`: - -- `metricParameters`: JSON object containing ancillary data parameters for the operand that should should be resolved to single timestamp / metric key-value pair based on the [Implementation](#implementation) section. -- `metricParametersArray`: an array of JSON objects containing ancillary data parameters for operands that should be resolved to an array of timestamp / metric key-value pairs based on the [Implementation](#implementation) section. - -### `SUM` - -#### Function parameters - -- `metricParametersArray` - -#### Operation - -Sum up all the metric values from the resolved `metricParametersArray` to get the total metric value. - -`SUM` supports operation over time series for aggregation. - -### `AVG` - -#### Function parameters - -- `metricParametersArray` - -#### Operation - -Sum up all the metric values from the resolved `metricParametersArray` and divide by its element count to get the average metric value. - -`AVG` supports operation over time series for aggregation. - -### `MAX` - -#### Function parameters - -- `metricParametersArray` - -#### Operation - -Select the largest metric value from the resolved `metricParametersArray`. - -`MAX` **does not** support operation over time series for aggregation. - -### `MIN` - -#### Function parameters - -- `metricParametersArray` - -#### Operation - -Select the lowest metric value from the resolved `metricParametersArray`. - -`MIN` **does not** support operation over time series for aggregation. - -### `DIFF` - -#### Function parameters - -- `metricParametersArray`: this should be restricted to exactly 2 element array. - -#### Operation - -Subtract the second element metric value from the first element metric value from the resolved `metricParametersArray` to obtain difference between provided metrics. - -`DIFF` **does not** support operation over time series for aggregation. - -### `CONV` - -#### Function parameters - -- `metricParameters` -- `priceIdentifier`: string choice among price identifiers approved by UMA governance.

Depending on the status of `inverse` parameter: - - if `inverse` is not provided or set to `false` multiply the metric value from the resolved `metricParameters` with resolved `priceIdentifier` from Step 2. - - if `inverse` is provided and set to `true` divide the metric value from the resolved `metricParameters` by resolved `priceIdentifier` from Step 2. - -`CONV` supports operation over time series for aggregation. diff --git a/research/uma/umips/Implementations/oolongswap-volume.md b/research/uma/umips/Implementations/oolongswap-volume.md deleted file mode 100644 index 4871279e..00000000 --- a/research/uma/umips/Implementations/oolongswap-volume.md +++ /dev/null @@ -1,55 +0,0 @@ -## Title - -Oolongswap Monthly Volume KPI Option Calculation - -## Summary - -Oolong is an AMM built on the Boba L2 Network.

document is not up to date the voters should refer to the canonical list of vault contract addresses at [MAI Finance Docs](https://docs.mai.finance/functions/smart-contract-addresses). - -### Event log method - -1. For each listed Vault contract above fetch all emitted `BorrowToken`, `PayBackToken`, `BuyRiskyVault` and `LiquidateVault` events emitted till the last available block relative to the request timestamp. Note that only one of `BuyRiskyVault` or `LiquidateVault` events are available for particular contract depending on Vault contract version. -2. Add up all `amount` fields from all `BorrowToken` events from Step 1 and scale down by 18 decimals. This represents the gross MAI token amount borrowed from vaults till request timestamp. -3. Add up all `amount` fields from all `PayBackToken` events from Step 1 and scale down by 18 decimals. This represents the gross MAI token amount repaid back to vaults till request timestamp. -4. Add up all `amountPaid` fields from all `BuyRiskyVault` events from Step 1 and scale down by 18 decimals. This represents the gross amount of burned MAI tokens as a result of liquidated debt positions in v1/v2 vaults till request timestamp. -5.

Hence, it could be more efficient to use indexing services (e.g. The Graph Protocol) for voters to verify total amount of borrowed MAI. Note that not all Vault contracts have subgraphs available, but it should be then possible to use contract call method (described in the next section) as newer Vault versions have implemented the `totalBorrowed` method. - -1. Identify available subgraph API endpoints from the Vault contract list above. -2. Construct subgraph query by making sure that `number` parameter in the `block` object corresponds to the latest available block number relative to price request timestamp, e.g.: - ``` - { - protocols(first: 1, block: {number: 21215934}) { - totalBorrowed - } - } - ``` -3. Perform `POST` request on each of API endpoints identified in Step 1. As an illustration, `curl` request for the MATIC Vault on Polygon would look like: - ``` - curl -X POST \ - -d '{"query": "{protocols(first: 1, block: {number: 21215934}) {totalBorrowed}}"}' \ - 'https://api.thegraph.com/subgraphs/name/0xlaozi/qi-dao-mai-finance-og' - ``` -4. Take a note on the raw borrowed MAI (`totalBorrowed` key value) from the returned subgraph response for each vault API endpoint and scale it down by 18 decimals. -5. Add up all outstanding MAI debt amounts in supported vault contracts from Step 4. - -### Contract call method - -Accounting of total borrowed amounts is correctly implemented only in the newest Vault contract versions, thus this method must be used only for those Vaults that have empty subgraph column in the Vault contracts table above. - -1. Call the `totalBorrowed` method on each of supported Vault contracts (see note above) for the block number that is at or the latest before the request timestamp. Note that this method requires access to archive state node. -2. Take a note on the returned raw borrowed MAI from each of the contract calls in Step 1 and scale it down by 18 decimals. -3. Add up all outstanding MAI debt amounts in supported vault contracts from Step 2. - -### Combining results - -In case of event log method the results can be processed as is, but subgraph and contract call methods are complementary to each other (depending on vault contract version), hence their resulting MAI debt should be added together for further processing. - -### API endpoint - -For convenience QiDao protocol is serving the API endpoint passed as `Endpoint` parameter to the ancillary data. The returned value should be scaled down by 18 decimals to get outstanding MAI debt in all Vaults. As of time of authorship of this document it provides only real-time data that could be helpful for KPI option owners to track the value of their expected payouts. Before this API endpoint also implements historical lookback data the voters should follow the manual verification procedures detailed above. - -## Post processing - -Since QiDao has opted to provide minimum guaranteed payout of 1 Qi per KPI options token and currently the audited financial product libraries do not allow setting minimum payout floor above zero voters should perform post-processing on the borrowed MAI and return a value between 1 and 2 to the submitted price request: - -1. Divide resolved MAI debt amount with maximum threshold of 7,500,000,000 MAI and add 1 to this ratio. -2. In case the MAI debt exceeds 7,500,000,000 MAI the resolved price should be capped at 2. -3.

When the price goes up, seniors give up some of their assets to the juniors, and vice versa. It is epoch-based, meaning that users deposit the underlying asset for a set period of time and cannot enter and exit until the subsequent epoch.

Alternatively, this can be any other Chainlink aggregator if the TVL should be measured in a different currency than the pool price feed quote currency. If this parameter is omitted TVL would be measured in terms of pool underlying currency.* - -***Note 4:** Due to the characteristics of logarithmic function in the post-processing evaluated metric needs to be bounded between `MinTVL` and `MaxTVL` parameters.* - -## Rationale and usage - -Even though UMA oracle system allows for manual price verification, Chainlink price feeds are used as input here as BarnBridge SMART Alpha pool operation already is depending on Chainlink price feeds. - -In order to achieve better accuracy of payouts projects using SMART Alpha pool KPI options should ensure that epochs are advanced before the options expiration so that the time period between the last epoch advancement and options expiration is less than pool epoch period. Even though voters could recalculate theoretical balances for last epoch it would unnecessarily complicate the calculation, thus it is the responsibility of KPI option users to call `advanceEpoch` on the pool contract if needed. - -`TVLPriceFeed` parameter should be explicitly set even if the TVL measurement currency is the same as pool price feed quote currency because the SMART Alpha pool contract does not publicly expose the Chainlink aggregator contract address that is required to determine price feed decimal scaling. - -In case the TVL is measured in the pool price feed quote currency users of KPI options should be aware that it is not possible to change the `TVLPriceFeed` parameter (it is set in ancillary data upon KPI options contract deployment), hence the pool price feed oracle should not be changed till the expiration of KPI options. - -## Implementation - -1. Identify the underlying asset currency token by calling `poolToken` method on the the provided SMART Alpha pool contract address (passed as `Pool` parameter in the ancillary data). Also note the token name, symbol and decimals by calling `name`, `symbol` and `decimals` method on the returned token contract. In case `decimals` method fails 18 scaling decimals should be assumed. -2. Determine whether price feed data should be inverted for the TVL calculation by calling `description` method on the Chainlink aggregator contract (passed as `TVLPriceFeed` parameter in the ancillary data). This should return pricing pair description in the form "base / quote" currency. If the identified underlying asset currency from Step 1 corresponds to the price feed base currency then the price feed should be used without modification, but if the underlying currency corresponds to the price feed quote currency then price feed data should be inverted. -3. Determine the total value locked in terms of the underlying asset in the `Pool` contract at the request timestamp by calling `epochBalance` method on the SMART Alpha pool contract and scaling it down by underlying currency decimals from Step 1. Voters should make sure to call `epochBalance` at the latest available block at or before the request timestamp (access to Ethereum archive node would be required). -4. Determine the price of underlying token in terms of TVL measurement currency at the request timestamp by calling `latestAnswer` method on the `TVLPriceFeed` contract at the latest available block at or before the request timestamp and scaling it down by price feed decimals (call `decimals` method on the price feed contract). Invert the obtained price if this is required based on Step 2. -5. Multiply the underlying asset balance from Step 3 with the price from Step 4 to get TVL in KPI options target measurement currency. In case `TVLPriceFeed` parameter is omitted leave the TVL in terms of underlying asset currency from Step 3. -6. Identify all epoch advancements between the KPI options start timestamp (passed within the `Aggregation` parameter from the ancillary data) and the request timestamp by looking at `EpochEnd` events emitted by he SMART Alpha pool contract. Take a note on each epoch advancement block number, timestamp and advanced epoch number (`epochId` parameter in the logged events). -7. Assign weight factor for each epoch advancement from Step 6 calculated as the difference between the `epochId` of considered event and its preceding epoch advancement event. For the first identified epoch advancement this weight should be set to the integer number of full epoch periods (based on the `epochDuration` parameter of the SMART Alpha pool contract) that could theoretically fit in between the KPI options start timestamp and the first following epoch advancement event (note that this could also be 0 if the difference is less than the epoch period). -8. Determine the junior side liquidity for each advanced epoch from Step 6 by calling `epochJuniorLiquidity` method on the SMART Alpha pool contract at each epoch advancement block number. -9. Determine the total liquidity for each advanced epoch from Step 6 by calling `epochBalance` method on the SMART Alpha pool contract at each epoch advancement block number. -10. For each identified epoch advancement calculate its junior side dominance by dividing `epochJuniorLiquidity` from Step 8 with `epochBalance` from Step 9. In case `epochBalance` is 0 the junior side dominance should be set to 0. -11. For each identified epoch advancement calculate its target points based on the junior side dominance from Step 10. Actual target points should be calculated using a simple step-wise linear function that increases from 0 to 2 as junior dominance rises from 0% to 50%, then decreases back to 0 as junior dominance rises to 100%: - * if junior dominance is lower or equal to 50% assign target points calculated by multiplying junior dominance share with coefficient 4; - * if junior dominance is higher than 50% assign target points calculated by multiplying senior dominance share (this is 1 minus junior dominance share) with coefficient 4. -12. Calculate the weighted mean target points from Step 11 applying epoch advancement weights from Step 7 (representing number of full epoch periods between advancements). -13. Multiply TVL from Step 5 with weighted average target points from Step 12. - -## Post processing - -Since BarnBridge has opted to incentivize SMART Alpha pools in a non-linear payout function, voters should perform post-processing on the adjusted TVL from Step 13 and return a value between 0 and 1 to the submitted price request based on the parameters and formula below: - - - -where: - -`MaxTVL` is taken from ancillary data parameter and represents the upper metric bound that should return 1 as a price, - -`MinTVL` is taken from ancillary data parameter and represents the lower metric bound (it should be larger than zero) that should return 0 as a price, - -`BoundedTVL` makes sure that adjusted TVL from Step 13 is kept within the `MinTVL` and `MaxTVL` bounds with formula: - - - -Before returning the calculated price voters should round it leaving `Rounding` number of decimals based on the provided ancillary data parameter. - -## Intended Application - -It is intended to deploy the documented KPI options separately for each incentivized SMART Alpha pool using [LSP contract](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/financial-templates/long-short-pair/LongShortPair.sol) with `General_KPI` price identifier approved in [UMIP-117](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-117.md).

A crvToken is an LP token for a curve pool and also has an associated swapContract. Component assets and swap contracts for each curveToken can be viewed [here](https://github.com/DefiLlama/DefiLlama-Adapters/blob/main/projects/helper/unwrapLPs.js). - - -### General vault calculation: - -1. Determine the crvToken from the list above (with the exception of "Crv_perpetual_vault", see section below). -2. Call `balance()` on the vault contract. This will return the underlying balance of the "crvToken" for the specific vault. Depending on the vault, this "crvToken" balance can be split between multiple contracts including in some scenarios a "gauge" contract and the "vault" contract. -3. Determine the total outstanding LP tokens by calling `totalSupply()` on the "crvToken" contract. -4. For each "crvToken" there is an associated "swapContract", which holds the underlying assets. Component assets and swapContracts for each "crvToken" are listed here. `balanceOf()` can be called on the underlying token contract for each token to return the amount of that token in the "swapContract". -5. For each component asset divide the balance held by the "swapContract" from Step 4 by total outstanding LP tokens from Step 3 and multiply by the vault underlying "crvToken" balance from step 2. This should estimate the underlying component asset balances indirectly held by the vault. -6. Each component asset should be priced in USD for the same timestamp. DeFiLlama estimates this by using aggregated CoinGecko prices, but all voters should verify that results agree with broad market consensus. -7. Calculate the sum of all component assets in USD from Step 6 and also add the Crv_perpetual_vault TVL (see section below). - -### Crv_perpetual_vault calculation: - -1. For the Crv_perpetual_vault TVL calculation, voters should call the `locked` method on the Vote-escrowed CRV contract (this corresponds to the "crvToken" address for the Crv_perpetual_vault) by passing vault contract address as parameter. This represents CRV locked in vote escrow by the Crv_perpetual_vault. -2. CRV locked from Step 1 should be converted to USD for the same timestamp as other vault underlying asset components. DeFiLlama estimates this by using aggregated CoinGecko prices, but all voters should verify that results agree with broad market consensus. - -### Crv_eth_vault calculation: - -DeFiLlama does not correctly calculate the underlying balance for the Crv_eth_vault, since the associated "swapContract" for ETH/sETH holds ETH that cannot be estimated with the `balanceOf` method. DeFiLlama estimates ETH balance by multiplying sETH balance by 2. This does not return completely accurate results, because the sETH/ETH pool is not weighted equally. - -1. Voters should subtract the chainTvls.Ethereum.tokensInUsd[i].tokens.SETH value from tvl[i].totalLiquidityUSD. -2. Separately query for the correct sETH and ETH balances for the underlying Crv_eth_vault swap contract (0xc5424B857f758E906013F3555Dad202e4bdB4567). -3. Multiply those balances by the respective sETH and ETH USD prices for the same timestamp and sum these results. DeFiLlama estimates this by using aggregated CoinGecko prices, but all voters should verify that results agree with broad market consensus. -4. Add the result from step 3 back to [tvl[i].totalLiquidityUSD - chainTvls.Ethereum.tokensInUsd[i].tokens.SETH] to get the TVL result. - -***Note:** The adjustment for Crv_eth_vault would become redundant if DeFiLlama corrects its methodology.* - -## Post processing - -StakeDAO TVL calculation would be used for resolving payout to StakeDAO KPI options program recipients. The expected payout should be 10 SDT per one option if the USD 200 million TVL threshold is reached and 1 SDT in case if it is below this target. Since at the time of planned KPI options deployment the audited binary options financial product libraries do not allow setting custom payouts, the voters will need to perform price processing and should return the expected payout instead of raw metric: - -* If the rounded StakeDAO TVL was at least USD 200 million, then resolve request as 10. -* If the rounded StakeDAO TVL was below USD 200 million, then resolve request as 1. diff --git a/research/uma/umips/Implementations/suINT-KPI-1stepoch.md b/research/uma/umips/Implementations/suINT-KPI-1stepoch.md deleted file mode 100644 index 8137cd29..00000000 --- a/research/uma/umips/Implementations/suINT-KPI-1stepoch.md +++ /dev/null @@ -1,45 +0,0 @@ -## Title: -SuperUMAn DAO Epoch One KPI - -## Summary: -The SuperUMAn DAO wishes to use KPI Options to incentivize the community to continue the pursuit of cross-DAO integrations with UMA financial products.

Determine daily query timestamp for metric data: - - If `RequestTimestampOverride` parameter is provided its value should be used as an override for the actual price request timestamp. Though this should always be ignored if the provided `RequestTimestampOverride` value exceeds actual price request timestamp. - - Daily query timestamp should be set to the closest 24:00 UTC timestamp at or before effective request timestamp expressed as numeric Unix timestamp. -2. Process `QueryString` parameter to replace any supported macros with actual values: - - `` should be replaced with the value of daily query timestamp. - - `` where `[N]` is expected to be integer value of days should be replaced by the value of daily query timestamp subtracted by `[N] * 86400` seconds. As an illustration, `` would be replaced by the timestamp that is 30 days before the daily query timestamp. - - `` should be replaced with the latest block number that is at or before the daily query timestamp. - - `` where `[N]` is expected to be integer value of days should be replaced with the latest block number that is at or before the daily query timestamp that had been reduced by `[N] * 86400` seconds. As an illustration, `` would be replaced by the corresponding block number for the timestamp that is 30 days before the daily query timestamp. - - For `` and `` macros above identify the relevant blockchain by the value of passed `ChainId` parameter (defaults to `1` for mainnet Ethereum if not explicitly provided). As a helper one can use Snapshot's [block finder query](https://blockfinder.snapshot.org), but verifiers are free to use their own tools to identify the matching block number. - - `` indicates that the requested data contains multiple entries (`CollectionKey` parameter must have been provided) and the query should be paginated by the verifier querying the API multiple times. - - On the first run `` should be replaced with `first:1000`. If the returned data contains exactly 1000 entries the query should be repeated by following the steps below. - - On the second run `` should be replaced with `first:1000,skip:1000` and any repeated iterations should increment the value of `skip` key by `1000` (e.g. `first:1000,skip:2000` for the third run and so on). - - Stop the repeated query if any of previous requests results in less than 1000 entries. Verifiers should aggregate the results of all queries combining returned entries under the `CollectionKey` path (see Step 5 below). -3. If `SubgraphId` parameter is not present this indicates usage of hosted service and API endpoint should be set to the value of `Endpoint` parameter. When `SubgraphId` is provided the API endpoint should be set to `"https://gateway.thegraph.com/api//subgraphs/id/"` where `` should be replaced with verifier's individual Graph [API key](https://thegraph.com/docs/en/querying/managing-api-keys/) and `` replaced with the value of `SubgraphId` parameter. -4. Query `POST` method on the subgraph API endpoint from Step 3 with following JSON data object: `{"query": ""}` where `` should be replaced with the macro processed `QueryString` parameter from Step 2. The returned JSON object should contain `data` object with requested elements. In case verifiers do not have API keys for the decentralized network the processed query can still be manually executed on the playground interface at `"https://thegraph.com/explorer/subgraph?id=&view=Playground"` where `SUBGRAPH_ID` should be replaced with the value of `SubgraphId` parameter. -5. Determine the value of tracked metric from the returned `data` object from Step 4: - - If the `data` object contains single element for the tracked metric (this can also be deducted by the absence of `CollectionKey`parameter) traverse the nested elements of `data` object by following key path provided in `MetricKey` parameter where nested key strings are separated by dots (`.`). Use the value of identified key for the tracked metric at the daily query timestamp. - - If the `data` object contains a collection of elements first identify the relevant collection by traversing the nested elements of `data` object with the key path provided in `CollectionKey` parameter where nested key strings are separated by dots (`.`). Then for each element of the identified collection traverse its elements by following key path provided in `MetricKey` parameter where nested key strings are separated by dots (`.`). Sum up the values of identified key elements within the collection to calculate the value of tracked metric at the daily query timestamp. - - If due to performed [operation](https://github.com/UMAprotocol/UMIPs/blob/master/Implementations/metric-operations.md) on the metric its ancillary data has inherited `ReturnFrom` parameter set to `rawMetric` the obtained value of tracked metric from this Step 5 should be paired with the daily query timestamp from Step 1 and passed as timestamp /metric key-value pair for the processing of dependant operation. Otherwise proceed with the next steps in this implementation. -6. If `AggregationMethod` is provided follow the instructions of the chosen method section from the [supported aggregation methods](https://github.com/UMAprotocol/UMIPs/blob/master/Implementations/aggregation-methods.md) using the metric time series (see below) for all the daily timestamps to derive single metric value. In case the string value in `AggregationMethod` is not supported ignore the aggregation and use the value of tracked metric at the single daily timestamp. - - If `TimestampKey` was not provided identify all daily timestamps at 24:00 UTC that are at or before effective request timestamp and not earlier than `AggregationPeriod` seconds before the effective request timestamp. Repeat the Steps 2 - 5 for each identified daily query timestamp to obtain an array of measured KPI metrics along with daily Unix timestamps for these data points to be processed by the selected aggregation method. If also `AggregationPeriod` is missing due to misconfiguration ignore the aggregation and fall back to the value of tracked metric at the single daily timestamp. - - If `TimestampKey` was provided follow the same instructions as in Step 5, but do yet not sum up the values of identified key elements within the collection. Also in a similar manner use the `TimestampKey` parameter value with any nested key strings separated by dots (`.`) to identify corresponding Unix timestamps for each of the elements of tracked metric (obtained by traversing `MetricKey` path before).

Identify all daily evaluation timestamps at the end of day (midnight UTC) that fall in between the start timestamp (passed within the `Aggregation` parameter from the ancillary data) and the request timestamp. -2. Identify the chain of the requesting contract (e.g. Ethereum or Polygon). -3. Identify the YEL staking contract (on the chain from Step 2) passed as `yelFarmingContract` parameter in the ancillary data. -4. Identify the incentivized LP token and its staked balances by calling `poolInfo(1)` method on the YEL staking contract from Step 3. Voters should make sure to call it at the latest available block at or before each evaluation timestamp identified in Step 1 (access to archive node would be required). In case the `stakingTokenId` parameter passed in the ancillary data has any other value than 1 modify the `poolInfo` call to contain it as its parameter value. Take a note on the returned LP token contract address (index 0 `stakingToken` from output) and staked LP token balances (index 1 ` stakingTokenTotalAmount` from output). -5. Identify LP contract reserve currencies by calling `token0()` and `token1()` methods on the LP contract from Step 4 (`stakingToken`). -6. Get total LP reserves by calling `getReserves()` method on the LP contract from Step 4 at the latest available block at or before each of evaluation timestamps from Step 1. This should return `token0` and `token1` balances as index 0 `_reserve0` and index 1 `_reserve1` respectively for each evaluation timestamp. -7. For both LP reserve tokens from Step 5 get the latest available pricing before each of evaluation timestamps from CoinGecko: - * Based on CoinGecko [API documentation](https://www.coingecko.com/api/documentations/v3#/contract/get_coins__id__contract__contract_address__market_chart_range) construct price API request with following parameters: - * `id`: CoinGecko platform id - find the chain from Step 2 in https://api.coingecko.com/api/v3/asset_platforms endpoint (e.g. "ethereum" or "polygon-pos"); - * `contract_address`: reserve token address from Step 5; - * `vs_currency`: TVL measurement currency based on the passed `TVLCurrency` parameter in the ancillary data (e.g. "usd"); - * `from`: start timestamp (passed within the `Aggregation` parameter from the ancillary data); - * `to`: request timestamp; - * Note that some tokens might not be supported by CoinGecko on all chains - in such case consult supported currency/platform list at https://api.coingecko.com/api/v3/coins/list?include_platform=true and replace to supported `id` and `contract_address` for the same reserve token. As of time of authorship of this document YEL is supported only on Ethereum chain, hence its Polygon address would need to be replaced with 0x7815bDa662050D84718B988735218CFfd32f75ea on Ethereum; - * Example API request for YEL token pricing information: https://api.coingecko.com/api/v3/coins/ethereum/contract/0x7815bDa662050D84718B988735218CFfd32f75ea/market_chart/range?vs_currency=usd&from=1630454400&to=1631491200 - * Locate the `prices` key value from CoinGecko API response - it should contain a list of [ timestamp, price ] values. For each evaluation period (Step 1) choose the price at the latest timestamp before the evaluation timestamp (CoinGecko timestamps are in milliseconds); - * Voters should verify that obtained price results agree with broad market consensus. -8. Scale down LP reserve balances from Step 6 with their respective decimals (call `decimals()` method on the token contracts from Step 5). -9. Multiply each LP reserve token balance from Step 8 with its price from Step 7 for each evaluation timestamp. -10. Sum both LP reserve balance values from Step 9 to get total value of the pool for each evaluation timestamp. -11. Get total LP token supply by calling `totalSupply()` method on the LP contract from Step 4 at the latest available block at or before each evaluation timestamp. -12. Scale down LP token supply series from Step 11 with its decimals (call `decimals()` method on the LP contract from Step 4). -13. Divide total LP pool values from Step 10 with the corresponding timestamp token supply from Step 12 to get the price per 1 LP token for each evaluation timestamp. -14. Scale down staked LP token balances from Step 4 (`stakingTokenTotalAmount`) with its decimals (call `decimals()` method on the LP contract) for each evaluation timestamp. -15. Multiply staked LP token balances from Step 14 with their corresponding prices from Step 13 to obtain LP TVL in terms of `TVLCurrency` for each evaluation timestamp. -16. Calculate average from the daily values in Step 15 to obtain chain specific staked LP TVL in terms of `TVLCurrency`. - -## Post processing - -Based on the `TVLCheckpoints` parameter from ancillary data voters should transform the measured average TVL from Step 16 to its corresponding price points. `TVLCheckpoints` contains key-value pairs where keys represent target TVL metric checkpoints and values indicate response price points. Voters should identify the largest TVL checkpoint (key) that is exceeded by the average TVL and return its corresponding price point (value) as resolved price request. - -As an example, based on the intended ancillary data parameters above if the average TVL of LP staked in YEL on Ethereum at KPI options expiration was USD 260,000 price should be resolved to 0 (TVL is exceeding only key "0" checkpoint).

If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work.

Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Remote Network Interaction; Use with the GNU General Public License. - - Notwithstanding any other provision of this License, if you modify the -Program, your modified version must prominently offer all users -interacting with it remotely through a computer network (if your version -supports such interaction) an opportunity to receive the Corresponding -Source of your version by providing access to the Corresponding Source -from a network server at no charge, through some standard or customary -means of facilitating copying of software. This Corresponding Source -shall include the Corresponding Source for any work covered by version 3 -of the GNU General Public License that is incorporated pursuant to the -following paragraph. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the work with which it is combined will remain governed by version -3 of the GNU General Public License. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU Affero General Public License from time to time. Such new versions -will be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU Affero General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU Affero General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU Affero General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE -USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF -DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD -PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), -EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF -SUCH DAMAGES. - - 17. Interpretation of Sections 15 and 16. - - If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -state the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software: you can redistribute it and/or modify - it under the terms of the GNU Affero General Public License as published - by the Free Software Foundation, either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU Affero General Public License for more details. - - You should have received a copy of the GNU Affero General Public License - along with this program. If not, see . - -Also add information on how to contact you by electronic and paper mail. - - If your software can interact with users remotely through a computer -network, you should also make sure that it provides a way for users to -get its source. For example, if your program is a web application, its -interface could display a "Source" link that leads users to an archive -of the code. There are many ways you could offer source, and different -solutions will be better for different programs; see section 13 for the -specific requirements. - - You should also get your employer (if you work as a programmer) or school, -if any, to sign a "copyright disclaimer" for the program, if necessary. -For more information on this, and how to apply and follow the GNU AGPL, see -. diff --git a/research/uma/umips/README.md b/research/uma/umips/README.md deleted file mode 100644 index cc5c9096..00000000 --- a/research/uma/umips/README.md +++ /dev/null @@ -1,6 +0,0 @@ -# UMIPs - -This is a repository for UMA Improvement Proposals (UMIPs). -UMIPs are used to propose and approve new financial contract templates, new price identifiers, and make other changes to governance of the UMA DVM (data verification mechanism). - -To contribute to this repo, first review [UMIP-1](UMIPs/umip-1.md).

This will involve adding it to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 0.1 WETH per request. - -## Motivation -ETH is the most liquid currency on Ethereum. Many users on Ethereum like to borrow against their ETH to get leverage on their ETH. At the time of writing, over 1.9mm ETH are locked in MakerDAO in this fashion. To allow synthetic tokens created with the EMP to take advantage of this liquidity and desire for leverage, WETH (ETH wrapped in an ERC20) seems like an important and safe addition to Dai as the second approved collateral currency. - -WETH as collateral is expected to have a variety of deployments. The timing for adding it now, and the immediate application, is for use with USDETH, which will enable the creation of yUSD, a yielding dollar token. This price identifier is described in UMIP 6. - -## Technical Specification -To accomplish this upgrade, two changes need to be made: -- The WETH address, [0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2](https://etherscan.io/token/0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2), needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 0.1 needs to be added for the WETH in the Store contract. - -## Rationale - -The rationale behind this change is giving deployers more useful collateral currency options. WETH needs to be used instead of ETH due to it being an ERC20, whereas native ETH is not. - -0.1 was chosen because 0.1 WETH is about twice as large as the current DAI final fee (10 DAI). This accounts for the fact that WETH is a much more volatile asset. Voters cannot change the final fees immediately when the price changes on collateral assets, so this additional cushioning helps protect the system from DoS attacks in times of volatility. - -## Implementation - -This change has no implementation other than the two aforementioned governor transactions that will be proposed. - -## Security considerations -Since WETH is a persistently valuable ERC20 token, including it as a collateral currency should impose no additional risk to the protocol. - -The only security implication is for contract deployers and users who are considering using EMP contracts with WETH as the collateral currency. They should recognize that, relative to most fiat currencies, WETH is much more volatile than Dai. This volatility should be taken into account when parameterizing or using these EMP contracts. - -For added assurance, WETH is not listed on the [buggy ERC20 contracts list](https://github.com/sec-bit/awesome-buggy-erc20-tokens/blob/master/bad_tokens.all.csv). diff --git a/research/uma/umips/UMIPs/umip-100.md b/research/uma/umips/UMIPs/umip-100.md deleted file mode 100644 index fff3227c..00000000 --- a/research/uma/umips/UMIPs/umip-100.md +++ /dev/null @@ -1,101 +0,0 @@ -# Headers - -| UMIP-100 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add `SelfMintingDerivativeFactory` as `Creator` in DVM registry | -| Authors | Pascal Tallarida (pascal@jarvis.network) | -| Status | Approved | -| Created | 12/05/2021 -| Discourse link | https://discourse.umaproject.org/t/add-selfmintingderivativefactory-as-creator-new-uma-fork/1079 | - -# Summary - -Last year, we have forked the perpetual contracts implementation of UMA and proposed the [UMIP-34](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-34.md) to integrate it within the DVM. We called this contract PerpetualPoolParty. This fork allows our synthetic assets to be multi-collateralized (multiple collateral linked to multiple Derivatives contract can back the same synthetic asset), perpetual (but without stability fee, funding rate etc.), and permissioned (only our whitelisted Smart Contracts can mint them). - -The UMA’s governance approved this fork earlier this year, allowing us to launch our mainnet. - -The PerpetualPoolParty was a “broker contract” allowing the end-users to trade against a smart contract (the broker's liquidity pool) which is the sole Token Sponsor: when a user wants to buy a synthetic asset, it triggers a mint transaction where the liquidity pool self-mints a synthetic fiat with a collateral in USDC deposited by liquidity providers, and sell this synthetic fiat for USDC to the end-user, at the Chainlink price, within the same transaction. - -Now we are about to launch our “bank contract” which allows anyone to be a Token Sponsor, pretty much like the EMP. Yet, we could not use the EMP due to some specification of our protocols (multi-collateral synthetic assets, perpetual, set minting limits, etc.). So we forked PerpetualPoolParty. - -More information regarding the broker and bank protocols can be found [here](http://bit.ly/Synthereum_Manifesto). - -The goal of this UMIP is to integrate `SelfMintingDerivativeFactory` in the DVM. - -Once `SelfMintingDerivativeFactory.sol` receives the `Creator` role it will register every `SelfMintingPerpetualMultiParty.sol` that is deployed through it with the UMA Registry so they can request prices from the DVM. - -# Motivation - -The "broker contract" was the first piece of our protocol to allow anyone to swap a synthetic assets for USDC at the oracle price (using Chainlink); this allows for the creation of a primary market, and help synthetic assets listed on secondary markets to maintain their peg through arbitrage. Although, the "broker contract" requires liquidity to function, which limits the issuance of synthetic assets. - -The "bank contract" will allow us to scale as it will allow anyone to self-mint perpetual synthetic assets by depositing a supported collateral, without funding fees or interests. The combination of the two contracts (bank and broker) provides a mechanism to maintain a peg: if the price is above the peg, one can mint a synthetic asset, sell it on a secondary market for USDC, and use part of these USDC to buy back the synthetic assets from the broker contract, to burn them and redeem their collateral. It also provides an instant liquidity to any synthetic assets minted though the "bank contract": one could use $UMA to self-mint jEUR, and instantly sell them for USDC at the oracle price. Today, self-minting a synthetic dollar using UMA occurs a slippage when selling it. - -The "bank contract" charges a fee, paid in the collateral deposited, when the user mints, deposits, repays and redeems. The fees are then transferred to the Jarvis protocol's treasury. - -Giving `Creator` role to `SelfMintingDerivativeFactory.sol` would allow more scalable and liquid synthetic assets to be backed by the UMA liquidation/dispute system, since every newly deployed derivative (`SelfMintingPerpetualMultiParty.sol`) is registered with the DVM. - -# Technical Specification - -### Here is a breakdown on the whole deployment process of a new derivative: - -1. Our DAO address (which is currently a team address until the DAO is set up) calls `deployOnlySelfMintingDerivative()` of `Deployer.sol`. -2. `Deployer.sol` calls `createPerpetual()` function of `SelfMintingDerivativeFactory.sol` and this function will use the `createPerpetual()` function of the contract `SelfMintingPerpetutalMultiPartyCreator.sol` that will call `SelfMintingPerpetualMultiPartyLib.sol` which will deploy a new `SelfMintingPerpetualMultiParty.sol` contract. -3. In the process of deployment `SelfMintingDerivativeFactory.sol` uses the internal function of `SelfMintingPerpetutalMultiPartyCreator.sol` called `_setControllerValues()` to set the CapMintLimit, CapDepositRatio and Fee for the new `SelfMintingPerpetualMultiParty.sol` in the `SelfMintingController.sol`. - - -### Modifications done: - -1. Transaction fees : we have added functions to calculate and to transfer fees that are being paid when a user mint, redeem and repay. Fees are paid with the collateral. Fee calculation = the number of tokens to mint, redeem or repay * GCR * fee (in %). - -2. Deposit collateral ratio (DCR) is capped : this is the ratio between the deposited collateral and number of tokens minted. It comes in addition to the GCR: the latter sets a collateral ratio limit below which it is not possible to mint; the DCR sets a limit above which it is not possible to mint; this is done in order to prevent someone to manipulate the GCR. Like the GCR, the DCR is used in the mint, deposit and repay function. - -3. Minting is capped : it limits the number of tokens that the derivatives can mint so we can scale according to the demand, liquidity and security. Caps will be increased as security audits are being completed, and as liquidity on our Broker contracts (PerpetualPoolParty) deepen. Also the `CapMintLimit` parameter allows us to avoid a situation in which arbitrage opportunities could potentially be blocked thus affecting the peg of our synthetic tokens across various DEXes. By setting the cap below the currently minted synthetic assets on our broker contract we ensure that an attacker can not self-mint a synthetic asset and redeem an amount equal to the total amount of assets minted from our broker contract, which would block users from redeeming USDC from the broker contract until new tokens are minted and this could lead to impossibility to perform arbitrage and keep the peg with secondary markets. -Under certain conditions, limiting the cap has a downside: if there is not enough synthetic asset on the secondary market to buy them to liquidate a position, it is possible that the limit prevents minting enough synthetic to do so. - -4. Make the contract permissionless : the PerpertualPoolParty contract was permissioned (only whitelisted pools can be a Sponsor). We changed this so anyone can become a Sponsor, like it is now in any UMA derivatives of course. - -5.

Liquidity pools hold USD-stablecoin such as USDC and are the sole Token Sponsor: a mint is a transaction where the liquidity pool self-mints a synthetic fiat with a collateral in USDC, and sell this synthetic fiat for USDC to the end-user, at the Chainlink price. - -The [UMIP-34](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-34.md) has been approved by the governance, allowing us to launch our synthetic assets collateralized by USDC on the mainnet ($1M TVL, $700k of synthetic assets minted; we have capped the amout of synthetic assets that can be minted until more audits are conducted; the protocol has received one full audit from Halborn, and a second one is undergoing with Ubik). - -In order to increase the liquidity, security and scalability of our synthetic assets we have decided to deploy a new `DerivativeFactory.sol` contract and re-deploy our existing Derivatives/Pools (jEUR/USDC, jGBP/USDC, jCHF/USDC) in order to lower some of the required parameters like starting GCR and Liquidation threshold. - -Earlier last year we have deployed a `Manager.sol` contract, which handles the assignment of Roles, instead of each pool having this functionality embeded. Also the `Manager.sol` contract is the only entry point for the `emergencyShutdown` functionality which can be called by Jarvis DAO and UMA DAO. - -Since the handling of the roles has been passed to `Manager.sol` contract, this gave us a good opportunity to modify and clean up the current Pool/Derivative contracts from any unnecessary logic previously stored in them. - -Once `DerivativeFactory.sol` receives the `Creator` role it will register every `PerpetualPoolParty.sol` that is deployed through it with `Registry.sol` so they can request prices from the DVM. - -# Motivation - -The changes in the collateral ratio and liquidation threshold for USDC-backed synthetic assets allow us to scale more without adding additional risks.

Adding BASK as a price collateral currency for the creation of synthetic tokens is the purpose of this collateral UMIP. - -## Motivation -Adding BASK as a collateral currency would give Basket DAO community members the ability to create synthetic tokens for the creation of KPI options. The creation of these tokens using the UMA protocol, will not only allow for growth in the Basket DAO community but would also raise the current TVL of the UMA protocol thus benefitting both communities. Basket DAO has also expressed interest in other UMA protocol products as well. - -## Technical Specification - -To accomplish this upgrade, the following changes need to be made: -- The [BASK address](https://etherscan.io/address/0x44564d0bd94343f72e3c8a0d22308b7fa71db0bb) needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 4 BASK in the proposed collateral currency needs to be added for BASK in the Store contract. - -## Rationale -Adding BASK as a collateral type would give the Basket DAO community the ability to create the KPI options that it has expressed it would like to mint. These options will not only help in the growth to the Basket DAO community, but the adding BASK as a collateral currency would also increase the UMA protocols TVL, thus benefitting both communities. The Basket DAO community has also expressed interest in creating Call options in the future. Thus adding the Basket DAO governance token BASK as a collateral type will benefit UMA both now, and into the future. Basket DAO while fairly new shows good liquidity and its value keeps on par with other similar coins. - -## Implementation - -This change has no implementations other than the afore mentioned governor transactions - -## Security considerations -BASK is the governance token of the Basket DAO protocol. Its implementation as a collateral currency should pose no security threats other than normal market volatility. That being said $UMA holders should evaluate the ongoing cost and benefit of supporting this asset as collateral if liquidity concerns are identified. UMA holders should take note of the collaterals nature as liquidity if the collateral changes or if added robustness(Eg. via TWAPs are necessary to prevent market manipulation. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-106.md b/research/uma/umips/UMIPs/umip-106.md deleted file mode 100644 index 495a34ad..00000000 --- a/research/uma/umips/UMIPs/umip-106.md +++ /dev/null @@ -1,1156 +0,0 @@ -# HEADERS -| UMIP-106 | | -|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add BANDUSD, USDBAND, SDTUSD, USDSDT, KP3RUSD, USDKP3R, CREAMUSD, USDCREAM, CHAINUSD, USDCHAIN, ERNUSD and USDERN as price identifiers| -| Authors | John Shutt (john@umaproject.org), Deepanshu Hooda (deepanshuhooda2000@gmail.com), Aaron (bitznbrewz) | -| Status | Approved | -| Created | May 2, 2021 | -| Link to Discourse | [Link](https://discourse.umaproject.org/t/add-band-sdt-kp3r-cream-lpool-chain-and-sand-price-identifiers-draft/1145) | - - -# SUMMARY - -The DVM should support price requests for the below price indices: - -- BAND/USD -- USD/BAND -- SDT/USD -- USD/SDT -- KP3R/USD -- USD/KP3R -- CREAM/USD -- USD/CREAM -- CHAIN/USD -- USD/CHAIN -- ERN/USD -- USD/ERN - -The canonical identifiers should be `BANDUSD`, `USDBAND`, `SDTUSD`, `USDSDT`, `KP3RUSD`, `USDKP3R`, `CREAMUSD`, `USDCREAM`, `CHAINUSD`, `USDCHAIN`, `ERNUSD` and `USDERN`. - -# MOTIVATION - -These price identifiers would allow the above currencies to be used for the creation of synths using currencies. These tokens were proposed to be used as collateral in UMIP #96. Examples of synths that could be created using these currencies would be yield dollars or covered call options. - -Proactively approving these price identifiers will make it easier for development teams and protocol treasuries to create new products using these ERC20 tokens and their price identifiers. - -# RATIONALE - -All of these base currencies have deep liquidity on Uniswap, SushiSwap, or both, and some have good liquidity on centralized exchanges, as well. The specifications for each price identifier are based on how we can find the most accurate price for the base currency. So, if a token has deep liquidity and high volume on Uniswap but little or no CEX activity, we would use a Uniswap TWAP. If a token has deep liquidity and high volume on two CEXs and Uniswap, we would take the median of the three prices (with a TWAP for Uniswap). - -# BAND - -## MARKETS & DATA SOURCES - -Markets: Binance, Sushiswap, and Coinbase-Pro - -* Binance: [BAND/USDT](https://api.cryptowat.ch/markets/binance/bandusdt/price) -* Coinbase Pro: [BAND/USD](https://api.cryptowat.ch/markets/coinbase-pro/bandusd/price) -* Sushi: [BAND/WETH](https://analytics.sushi.com/pairs/0xa75f7c2f025f470355515482bde9efa8153536a8) - -How often is the provided price updated?

This UMIP does not attempt to put any other restrictions on the content of the query, and instead leaves construction of the query up to the requester within ancillary data. - -Price settlement can happen in four ways: -- Return the `p1` value from ancillary data if the answer is "NO". -- Return the `p2` value from ancillary data if the answer is "YES". -- Return the `p3` value from ancillary data if the answer cannot be determined. -- Return the `p4` value if the answer cannot be determined AND there is either an `earlyExpiration:1` key value pair present in ancillary data, or there is a specific last possible request timestamp listed or implied in the ancillary data question and the active price request timestamp falls before that. - -# Motivation - -Approving this price identifier will allow for a variety of products without the burden of having to vote in additional price identifiers. Users could create: -- Prediction markets -- Insurance products -- Binary options - -# Data Specifications - -It is not possible to define specific data sources or markets for this identifier. Determination of data sources and results are left entirely up to voters at the time of settlement, as the best method of determining the results for each request will depend on the question being asked. - -# Price Feed Implementation - -No price feed is needed (or possible) for this price identifier. - -# Technical Specifications - ------------------------------------------ -- Price identifier name: YES_OR_NO_QUERY -- Base Currency: NA -- Quote Currency: NA -- Rounding: None, there is a predetermined set of results. -- Estimated current value of price identifier: NA - - -## Ancillary Data Specifications - -When converted from bytes to UTF-8, the ancillary data should be a dictionary object containing q (question), p1, p2, p3 and p4 keys and values. p4 is optional and will only apply in certain situations. - -``` -q:Did the Dallas Mavericks beat the Miami Heat January 6th, 2022?, p1:0, p2:1, p3:0.5, earlyExpiration:1 -``` - -The q value should contain the question that UMA voters should answer with. - -When this ancillary data dictionary is stored as bytes, the result would be: `0x713a446964207468652044616c6c6173204d6176657269636b73206265617420746865204d69616d692048656174204a616e75617279203674682c20323032323f2c2070313a302c2070323a312c2070333a302e352c206561726c7945787069726174696f6e3a31` - -When returned, the `p1-p4` values should be scaled by 1e18. Typically voter dapps in the UMA ecosystem abstract this scaling away from voters, so, more often than not, voters should input the values as they appear in the ancillary data. Price requestors should be mindful of this, and not scale their ancillary data inputs. - -If there are no p1, p2, p3 or p4 values present, values should default to: -- p1: 0 -- p2: 1 -- p3: 0.5 -- p4: -57896044618658097711785492504343953926634992332820282019728.792003956564819968 - -# Rationale - -This construction sacrifices assurances of determinism in favor of greater price identifier flexibility. The places the burden of correct construction on price requesters, but, in return, allows for quicker and easier development without needing to pass through UMA governance for each additional distinct query. This will allow for quite bespoke and speedy contract construction. - -p4 is intended to be used for situations where it is not a given that the price request (or contract settlement) should even occur yet. An example of this would be the UMA event-based expiry LSP. A request to settle an event-based expiry LSP can be submitted at any time but if the question can not be resolved yet it should be ignored. - -The default p4 value is the minimum int256 value and is used as a "magic number" to indicate that an event-based expiry request is invalid and the contract should continue as normal. For example, if the question is related to a basketball game on January 6th and a settlement request comes in on January 5th, the question can not be resolved yet, and voters should return the p4 value with the magic number to reject the settlement request. This value also moves the decimal place 18 spaces to the left, due to the default behavior of the UMA voting interface to scale input values to 18 decimals. After scaling by the interface, the value will be -57896044618658097711785492504343953926634992332820282019728792003956564819968 - -Notice that a p3 value would never be returned earlier than the final price request time noted in the ancillary data or the requesting contract's expiration timestamp and a p4 value would never be returned after that point. Consider an unresolvable question like, "Was the weather nice on January 6th, 2022?" If the question was asked on January 7th, 2022, you would return the p3 value. If the same question was asked on January 5th, 2022, you would return the p4 value. - -# Implementation - -1. Voters should decode the ancillary data and attempt to interpret the UTF-8 question. -2. Voters should first determine if this is an "early expiration" price request. This can either be designated in ancillary data by identifying that there is a key:value pair of `earlyExpiration:1` present, or by reading the question and determining that price request timestamp of the request (if using the original `OptimisticOracle` contract) or the price proposal timestamp (if using `OptimisticOracleV2`) is earlier than the expected event resolution time noted in ancillary data. -3. If this is an "early expiration" price request, voters should first determine if the question in the ancillary data can be resolved definitively at this point in time. If not, voters should return the p4 value if there is one, and the default p4 value from `Ancillary Data Specifications` if there is not. If yes, the voters should continue the process to assess the question. -4. If UMA voters believe that the answer to the question is no, they should vote return the p1 value (in the example given, they would return `0`). -5. If UMA voters believe that the answer to the question is yes, they should return the p2 value (in the example given, they would return `1`). -6. If a voter cannot make a determination about what the correct answer to the question is, or there is no question present, UMA voters should return the p3 value (in the example given, they would return `0.5`). -7. If there are no p1, p2, p3, p4 values in the ancillary data, voters should use the default values listed in `Ancillary Data Specifications`. -8.

The type of price that the DVM will return is dependent on the timestamp the price request is made at. This timestamp is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the closing index value of uSTONKS calculation is used at expiry. This is very similar to the uGAS token and this design is outlined in [UMIP 22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md). - -Because the uSTONKS index value is only used at expiry, it will not be possible for a token sponsor to become undercollateralized based upon its movement. This means that only the Uniswap TWAP will need to be queried in real-time with a price feed. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. - -## TECHNICAL SPECIFICATIONS -- Price Identifier Name: uSTONKS_0921 -- Base Currency: uSTONKS_0921 -- Quote currency: None. This is an index, but will be used with USDC. -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE -The uSTONKS token is an expiring token that settles at the end of the expiry month using the final exchange closing prices on the last business day of the month for the ten stocks in the basket. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because uSTONKS is a decentralized synthetic that trades continuously 24/7 whereas the underlying stocks in the uSTONKS index trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. Using price feeds from the exchanges to monitor collateral ratios of token sponsors could be problematic outside of market hours especially if there is significant news released or general macro market forces. Though some stocks are traded after hours, the ability to extract this price data is difficult and the frequency may not be consistent across all ten stocks. Therefore, using the uSTONKS token price itself to monitor collateral ratios is a much better alternative as it should reflect the actual price movements during exchange hours and also reflect expectations of price movements after market hours. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -The stocks chosen represent the stocks with the highest average comment volume on r/WallStreetBets. This index was picked on June 14th, 2021 using r/WallStreetBets comment analysis from swaggystocks.com, and will remain static throughout the life of the price identifier. - -## IMPLEMENTATION -Voters should determine which pricing implementation to use depending on when the price request was submitted. - -**At Expiry** - -If the price request's UTC timestamp is at 1633046400 (Oct. 1, 2021 00:00:00 UTC), a price request for uSTONKS for a given timestamp should be determined by performing the `At Expiry` process. - -To create a baseline for the uSTONKS index, a base price for each stock was chosen. These prices are the closing prices of each on 06/15/2021 and can be used by voters as reference values for their calculations. Voters are highly encouraged to verify these values themselves. This basket is static - it will not change over the life of the contract. - -| Ticker | Stock Price 06/15/2021 | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| AMC | 59.04 | -| BB | 13.99 | -| GME | 222.50 | -| CLNE | 11.11 | -| CLF | 22.86 | -| UWMC | 9.81 | -| SENS | 3.69 | -| SPY | 424.48 | -| CLOV | 13.77 | -| WKHS | 14.15 | - -Each stock also is assigned an index value base. The index is equally weighted, so each stock is assigned a base of 10. This means that on 06/15/2021 at close, the uSTONKS index would have been worth 100 with every component making up 1/10th of that index. - -To calculate the uSTONKS price, an UMA voter should: -1. Query for the close price of one component on September 30, 2021. It is recommended that voters use the Google Sheets GOOGLEFINANCE function. -2. Divide the September 30 price by the base price and multiply by the index value base (10) to get today’s index value. -3. Perform this function for each component in the index and sum all of the results together. -4. Round the result of step three to six decimal places - -An example of this calculation is shown in [this](https://docs.google.com/spreadsheets/d/1IbvIZUGQG2TW9YLrV7ykPr3P2F4PhvgvOU-4o2RujZc/edit?usp=sharing) Google Sheet. - -It is possible that, over the life of this price identifier, certain situations could arise that would affect the validity of the index calculation. Guidance is provided below for certain situations, but voters are free to come to an alternative consensus if a flaw in the methodology is identified or an unforeseen event occurs. - -1. In the case of a stock split, the base price of the stock should be divided by the number of shares that the stock is being split into. As an example - if GME issued a 4:1 stock split, the base price of GME, 222.50, would be divided by 4 and the new base index price would be 55.63. -2. In the case of a stock consolidation, the process is the same as for a stock split, except the base price should be multiplied by the number of shares being consolidated. - -**Before Expiry** - -If the price request's UTC timestamp is less than 1633046400 (Oct 1, 2021 00:00:00 UTC), voters will need to calculate a 2-hour TWAP for the uSTONKS_0921 token’s price in USDC. The following process should be used to calculate the TWAP. -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Sushiswap price is defined for each timestamp as the price that the uSTONKS_0921 / USDC pool returns in the latest block where the block timestamp is <= the price request timestamp. This is the price of 1 uSTONKS_0921 token in USDC. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. This results should be rounded to 6 decimals. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -## Security Considerations -Security considerations are focused on the use of the token price for monitoring collateral ratios. -- Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -- Mismatch between TWAP and gap higher in token price - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uSTONKS_0921, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -Security considerations, like the ones above, have been contemplated and addressed, but there is potential for security holes to emerge due to the novelty of this price identifier. - -Additionally, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Contract deployers should also ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier or editing its implementation if security holes are identified. diff --git a/research/uma/umips/UMIPs/umip-11.md b/research/uma/umips/UMIPs/umip-11.md deleted file mode 100644 index 54a389c0..00000000 --- a/research/uma/umips/UMIPs/umip-11.md +++ /dev/null @@ -1,50 +0,0 @@ -# Headers - -| UMIP-11 | | -| ---------- | ----------------------------------- | -| UMIP Title | Add renBTC as a collateral currency | -| Authors | Adrian Li (adrian@umaproject.org) | -| Status | Approved | -| Created | August 26, 2020 | - -## Summary - -This UMIP will add renBTC as an approved collateral currency. This will involve adding it to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 0.018 renBTC per request. - -## Motivation - -BTC is the world’s largest and most popular cryptocurrency by market capitalization as well as traded volume.

At the time of writing, over 7,000 WBTC are locked in MakerDAO in this fashion. - -To allow synthetic tokens created with the EMP to take advantage of this liquidity and desire for leverage, an ERC20-compliant representation of BTC is required. renBTC is an ERC20 token backed 1:1 with BTC using the decentralized Ren Protocol. - -renBTC as collateral is expected to have a variety of deployments. The timing for adding it now, and the immediate application, is for use with USDBTC, which will enable the creation of yUSD, a yielding dollar token. This price identifier is described in [UMIP-7](./umip-7.md). - -## Technical Specification - -To accomplish this upgrade, three changes need to be made: - -- The renBTC address, 0xeb4c2781e4eba804ce9a9803c67d0893436bb27d, needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 0.018 needs to be added for renBTC in the Store contract. -- The precision for the USDBTC price identifier needs to be amended to 8 decimals instead of the usual 18 in order to comply with renBTC’s 8 decimals of precision. - -## Rationale - -The rationale behind this change is giving deployers more useful collateral currency options. renBTC needs to be used instead of BTC due to it being an ERC20 representing BTC on the Ethereum blockchain, whereas native BTC does not exist on the Ethereum blockchain. - -renBTC was chosen in particular due to the fact that renBTC is the most popular (and largest) truly decentralized BTC-representing coin on the Ethereum blockchain. It is not being chosen at the exclusion of other possible BTC-representing coins, but it is a natural first choice for this purpose. - -While wBTC currently has larger market dominance than renBTC, it is worth noting that renBTC has already gained significant traction in the DeFi space. There exists a large amount of renBTC liquidity on Curve Finance ($98m), Balancer ($5m), and Uniswap ($150k). - -Large projects like Compound and Maker already have wBTC as a collateral type, so using renBTC within the UMA ecosystem can serve to differentiate the UMA community in terms of promoting a more decentralized version of BTC on the Ethereum blockchain. - -## Implementation - -This change has no implementation other than adding the collateral type to the whitelist. - -## Security considerations - -renBTC is minted with real BTC via RenVM, a trustless and decentralized virtual machine run by a network of nodes known as Darknodes. A user first sends BTC to a dedicated Bitcoin address generated by a dapp and verified by RenVM. The BTC is held in custody by RenVM's decentralized network of Darknodes. renBTC is backed 1:1 with BTC. - -Since renBTC is minted trustlessly as a token backed via the Ren Protocol, including it as a collateral currency should impose minimal risk to the protocol. - -The only security implication is for contract deployers and users who are considering using EMP contracts with renBTCC as the collateral currency. They should recognize that, relative to most fiat currencies, renBTC is much more volatile than Dai. This volatility should be taken into account when parameterizing or using these EMP contracts. diff --git a/research/uma/umips/UMIPs/umip-110.md b/research/uma/umips/UMIPs/umip-110.md deleted file mode 100644 index 1c0715d9..00000000 --- a/research/uma/umips/UMIPs/umip-110.md +++ /dev/null @@ -1,546 +0,0 @@ -## Headers - -| UMIP-110| | -| ------------------------|------------------------------------------------------------------------------------------------------------------------ | -| UMIP Title | Add BASKUSD, USDBASK, APWUSD, USDAPW, SNOWUSD, USDSNOW as supported price identifiers | -| Authors | Shawn C.

APWine is a protocol to trade future yield. DeFi users can deposit their interest bearing tokens of other protocols during defined future periods and trade in advance the future yield that their funds will generate.APWine tokenises the future yield leveraging two types of tokens in that process: -* Future Yield Tokens (FYT) (ERC20): They represent the future yield generated by an asset on one platform for a defined period. For example, one 30D-AAVE-ADAI-0 represents the yield generated by 1 ADAI (a.k.a. one DAI deposited on AAVE) during the first 30 days period. APWine features a dedicated exchange for users to sell and buy FYTs. - -* APWINE IBT (ERC20): The APWine interest bearing token. At any moment its holder can withdraw the corresponding depositing funds from the APWine protocol. APWINE IBT holders will receive an amount of FYT proportional of to the amount they hold (for the future the ibt corresponds to). One 30D-AAVE-ADAI represents one ADAI deposited to the ""30D-AAVE-DAI"" future. - -### Security considerations - -$UMA holders should evaluate the ongoing cost and benefit of supporting this asset as collateral and also contemplate removing support of this collateral if liquidity concerns are identified.

One example of a KPI metric is Integrations. Integrations serve to measure the activity of the protocol rather than assigning all of the value to the dollar amount generated by the protocol, as previously seen in UMA’s TVL KPI option. - -This UMIP enables the DVM to support price requests based on the number of qualifying integrations that occured during a specified timeline. This UMIP relies on the use of ancillary data, and will include a section on that below. - -A synthetic option is minted against a base collateral, in this case UMA. - - -# Motivation - -The primary motivation for the development of KPI options is to allow protocols and supporting organisations to incentivize DeFi users to assist them to reach identified targets by leveraging their community resources by sharing their value with their community members. - -Using integrations as a key metric directly benefits the UMA protocol because it encourages the community to build relationships in the broader DeFi community with the intention of providing tools that may be useful to teams who are currently unaware of what UMA has to offer. This creates a win-win across the board because it allows us to showcase our products and our products can then help other protocols to complete their goals. - -By establishing the terms of a qualifying integration, it allows for the community to reach out in a way that aligns with the current priorities of the UMA protocol- attracting attention to our strongest products and encouraging teams to test out a wide variety of use cases. - - -**It is anticipated that this Price Identifier will be used to create KPI Options, however it is acknowledged that it may be used for a variety of purposes.** - -# Data Specifications - -The UMA team will maintain a "green light" list of qualified integrations, which will be readily available upon request. This list will include details that voters need to assess the validity of the integration (e.g. launch and funding date of the contract so that voters can verify it is within the specified timeframe of the the current KPI option). Anyone can propose adding an integration to the list. Each integration will be added one at a time, after it has been discussed in the #voting channel in the UMA Discord. UMA tokenholders are encouraged to participate in these discussions in preparation for the formal proposed settlement. - -An integration will have been achieved when a DAO or other organisation funds an LSP contract which includes but is not limited to: - -* KPI options -* Call/Put options -* Range Bonds -* Success Tokens - -**Definitions:** -*Fund* - To fund means to take a DAO’s native token or another asset from the organisation's treasury and use it to collateralise an LSP contract The intention here is that these products will be used as a way to interact with the DAO's community or the organisation's supporters. There is an edge case here where a DAO or organisation might put money into a product with the intention to trade--This is not the spirit of this initiative and should not count towards an integration (although it is not discouraged behavior.) - -*Product Categories* - The four product categories have been explored and defined in a variety of articles, and many of the articles can be seen on UMA’s medium [page](https://medium.com/uma-project). These product types would primarily be built using UMA’s LSP (Long/Short Pair) contract, and in some cases can use the EMP contract. However, it is important to note that they will all be fully capitalized products, without any chance or need for liquidations. While multiple integrations per DAO/organisation can qualify, these should be substantively different products, rather than a repeat of the same product with variable parameters (such as expiry date). Should there be a dispute over whether an integration is "substantively different", a discussion is encouraged in the #voting channel on discord to inform UMA token holders of the arguments for and against so that they can make an informed decision about how many qualifying integrations have occurred at the time of the options expiry. - -*DAO* - A decentralized, autonomous organization. We would expect them to have a native token (although this is not a requirement) and a governance system. - -*Organisation* - An established entity which pre-dates the funding of the contract. - -**Ambiguity Considerations** - -It may be unclear whether new projects with illiquid tokens meet the criteria of a "DAO" or an "Organisation". We wouldn’t want to exclude this valuable integration type from inclusion in the KPI Options. This is a category that we will leave to UMA tokenholders to evaluate. As a guiding principle, a qualifying DAO is part of a good faith project; a disqualifying DAO would be one with no genuine attempt at a company or organization. Any ambiguities around the question of, "is it a DAO?" will be discussed in the #voting channel on the UMA Discord. It is especially important to the design of this UMIP that UMA tokenholders participate in these discussions to establish borad consensus on questions that don't have black and white answers. - -**Bonus Integrations** - -As seen below in the ancillary data section, this UMIP allows for the deployer of the contract to include bonus parameters for integrations above a set TVL threshold, denominated in $USD. If a deployer elects to include a bonus option, they should specify the minimum value required to qualify, the max number of integrations that can qualify for a bonus, and the multiplier to be applied to these integrations. To be consistent throught this UMIP, an integration will qualify for a bonus if it reaches the TVL threshold at any point in the life of the kpi option. If an integration qualifies for the specified bonus, it will be indicated on the "green light" list with a 🐋. - -It is assumed that the collateral token in most cases will not be USD. If there is a dispute over whether the collateral's value in USD, is in excess of level required for it to qualify for as a "Bonus Integration this should be discussed in the #voting channel in UMA Discord. - -**Additional Notes:** - -LSP contracts deployed by UMA for use by UMA do not count, but if UMA deploys a contract for use by another team, it is eligible as long as it meets the criteria above. - -Contracts included are not limited to Ethereum mainnet. Contracts on other chains where DVM message bridging is available (e.g. Polygon) will be included in consideration. - -The applied timeframe for this UMIP will be specified in ancillary data, and all qualifying integrations launched and funded during this timeframe should be counted. - -The "green light" list should not be considered the *only* source of truth, but rather a reflection of the discussions that take place within the community. The DVM has the ability and responsibility to challenge the validity of any integrations that have been included or excluded from the list if the broader consensus of UMA tokenholders is that it is within the spirit of this UMIP to do so. Any and all questions surrounding the validity of an integration can be brought up in further detail in the #voting channel on the UMA Discord. - -# Ancillary Data Specifications -The following pieces of data will be included as ancillary data when the contract is deployed, and will provide additional details & instructions to help voters correctly identify the number of qualifying integrations. - -* `startTimestamp` (unix timestamp) -* `maxBaseIntegrations` (non-negative integer) -* `maxBonusIntegrations` (non-negative integer) -* `bonusMinValue` (TVL threshold for bonus integrations represented in $USD) -* `bonusIntegrationsMultiplier` (non-negative number rounded to 2 decimals) -* `floorIntegrations` (non-negative integer) - -Ancillary data should be passed into the contract using the format in the example below. -``` -startTimestamp:1622527200, maxBaseIntegrations:15, maxBonusIntegrations:3, bonusMinValue:$1,000,000, bonusIntegrationsMultiplier:3.00, floorIntegrations:3 -``` - -If a contract deployer incorrectly formats or simply does not provide one of the parameters above, it will default to the following values. This means that if no ancillary data is present, the value returned should be 0. - -* `startTimestamp` (timestamp of contract deployment) -* `maxBaseIntegrations` (0) -* `maxBonusIntegrations` (0) -* `bonusMinValue` ($0) -* `bonusIntegrationsMultiplier` (0.00) -* `floorIntegrations` (0) - -# Technical Specifications - -- **Price identifier name:** *uDAO_KPI_UMA* -- **Base: Number of qualified DAO integrations -- **There is no quote currency in this option, as design feature. The collateral redemption is tied to the** *number of qualified integrations* **by design** - - **Intended Collateral Currency** *UMA*. -- **Rounding:** *Round to 2 decimals* - - -# Rationale - -* Linear scaling is used for sake of ease for contract deployment and for voters. Integrations that qualify for a bonus will simply be treated as multiple integrations as a way to recognize the increased value and work needed to get them across the finish line. - -* Allowing for a specified minimum payout is intented to account for the integrations that occurred prior to launch, in an effort to reward the community for hard work leading up to the launch of this KPI option. - -* Minimum payout may be established in ancillary data via the `floorIntegrations` parameter, or it can be baked into the contract. This is a design decision to be made by the contract deployer. If it is baked into the contract, details can be customized using the [financial-products-library](https://github.com/UMAprotocol/protocol/tree/master/packages/core/contracts/financial-templates/common/financial-product-libraries/long-short-pair-libraries). Allowing variations of this feature as a design choice allows deployers to weigh the pros and cons of exchainging simplisity for transparancy. In both cases, more details on minimum payout and scaling can be found within the deployed contract. - -* The decision to limit qualifying integrations to the LSP contract and highlight the listed product types was made in order to focus the community and align incentives with the strategic goals of the organization. - -* Setting it up to allow for all qualified launches to be counted throughout the period rather than just at the time of expiry helps to ensure that we are not missing out on any integrations that might expire before the KPI option does. The same logic is applied to bonus qualifying integrations. - -* Having a customized starting timestamp allows a contract deployer to include integrations that occur prior to launch of this option. This design feature can act to reward the community for prior work done and may also help keep momentum going while the current KPI expires. - -* The rationale for choosing integrations was to emphasize building DAO-to-DAO relationships and wider relationships between UMA and the wider Defi community. UMA’s product suite has increasingly gained focus and traction on DAO treasury management. However, it is not scalable for the development team to focus on promotion and integration efforts alone, and this KPI Option has been designed to help recruit the community to help. - - -# Implementation - -Step 1: Refer to "green light" list for finalized information on all qualified integrations. Assign 1 point for each integration on the list, including any integrations that have qualified for a bonus. - -Step 2: If an integration qualifies for a bonus, it will be indicated with a 🐋. These integrations are worth some multiplier of points *in addition* to the base points counted above. This multiplier will be specified in the ancillary data as `bonusIntegrationsMultiplier`. Keep track of bonus points and base points separately. - -* Note for step 2: In order for an integration to earn a 🐋 marker, it must meet the minimum TVL threshold as defined in the ancilary data parameter `minBonusValue`. This value is denominated in $USD rather than the collateral token, so discussion of $USD value had to take place in the #voting channel in UMA Discord in order for an integration to earn this status. For additional details on bonuses, see the above section on bonus integrations. - -Step 3: Tally up the total number of base points as well as the number of bonus points. At this point, the two numbers should be separate. - -Step 4: Using the ancillary data specifications for `maxBaseIntegrations` and `maxBonusIntegrations`, decide if your tally exceeds the max allowed for either category. If the value of your tally exceeds the max allowable points in either category, use the value provided by `maxBaseIntegrations` and `maxBonusIntegrations`. - -Step 5: Add base points plus bonus points from the step above for the total number of points. This is the value you will return. If the value returned would be lower than `floorIntegrations`, use the value provided by this field in ancillary data. - - -# Security Considerations - -Due to the bespoke nature of this UMIP, it should not be considered a standard against which future UMIPs can be measured without considering the amount of risk in establishing a set of rules as qualitative as is the case here. When assessing the risk of using qualitative data to determine an outcome, several things have been considered, such as the intended "in house" use of this UMIP, the intended recipients of the uDAO token, the intended outcome of the KPI option, and how to handle any ambiguities that could arise over the course of this option. - -How could metric manipulation occur? - -* By establishing a discussion system for determining qualitative validity of an integration, it reduces the ability of any individual to game the system. The DVM voters have the ability to determine if it appears that someone is acting maliciously and can disqualify any integrations that majority believe should not be included. - -How could this price ID be exploited? - -* The definition of the metric is inherently qualitative, and utilizes a logic that requires an integration to "earn" its way onto a curated list. This factor, which relies on human judgement, makes it inprobable that it will be exploited. - -Do the instructions for determining the price provide people with enough certainty? - -* Yes. Voters need only return the number of qualified integrations at the time of expiry. - -Are there any current or future possible concerns with the way the price identifier is defined? - -* It could be determined that the scaling is not appropriate in the event of overwhelming failure of the option. This would happen if we achieved too few integrations or if we reach the goal too quickly. -* Additionally, there is the potential for ambiguities to present that have not been considered at the time of writing. In this case it will be up to the DVM to determine the resolution of those ambiguities. -* It is possible that over the course of the KPI option, UMA could determine there are other products they would like to prioritize that are not defined in this UMIP. In that case, another KPI option can be launched to include that product. - -Are there any concerns around if the price identifier implementation is deterministic? - -* The potential for ambiguities over definitions has been addressed above and a method of resolving them recommened to UMA Tokenholders. diff --git a/research/uma/umips/UMIPs/umip-113.md b/research/uma/umips/UMIPs/umip-113.md deleted file mode 100644 index d19e54a5..00000000 --- a/research/uma/umips/UMIPs/umip-113.md +++ /dev/null @@ -1,53 +0,0 @@ -## Headers -| UMIP-113 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Register Polygon Oracle Root Tunnel | -| Authors | Nick Pai (nick@umaproject.org) | -| Status | Approved | -| Created | July 8, 2021 | - -## Summary (2-5 sentences) -This UMIP will have the effect of registering an oracle root tunnel contract that will enable the optimistic oracle deployed on Polygon to make cross-chain price requests to the DVM on mainnet Ethereum. - -## Motivation -[This document](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/polygon/README.md) describes a two way tunnel architecture that is built on top of the [canonical state transfer mechanism](https://docs.polygon.technology/docs/develop/l1-l2-communication/state-transfer) between Polygon and Ethereum.

In summary, the goal of this document is to encourage price requesters who use ancillary data to ensure that it can be decoded directly from `bytes` to `utf8` via standard client libraries such as `web3.js` and `ethers.js`, and that the `utf8`-encoded ancillary data is a comma-delimitted key-value dictionary just like the `SPACEXLAUNCH` example above. - -The current supported optimistic oracle "stamps" data to the ancillary data informing voters that any price requests were sent by an optimistic oracle.

If a value should contain `,` or `:` characters, such value should be enclosed in double quotes. The below listed key parameters will be used to instruct voters how to resolve a given price request for this identifier and request timestamp: - -- `Metric`: Short description reflecting the metric and units to be measured. -- `Endpoint` (optional): Link to data endpoint that should return the `Metric` at request timestamp. The response format should comply with the linked document from the `Method` parameter. The data endpoint should either allow passing the timestamp as parameter or returned data should include timestamp value for each returned data point. -- `Method`: Link to a descriptive source covering the objective and methodology for calculating a particular metric. This methodology should include how the calculation of the metric is measured. Links to repositories and explainer documentation are strongly recommended. Clearly articulate any post-processing required. -- `Fallback` (optional): In the event of the end-point not working or reporting false outcomes, a fallback ensures that UMA token holders can arrive at the proper result. If the methodology source demonstrates a fallback alternative, this field can be optional. -- `Key` (optional): Which key value from the `Endpoint` response should be used by voters for further processing of the price request. -- `Interval` (optional): This describes how request timestamps for pricing queries should be rounded and what is the granularity of historical data update frequency. -- `Aggregation` (optional): In case any time series data processing is required this describes processing method used (e.g. calculating TWAP, finding peak value, etc.) and also sets the start timestamp for such aggregation. -- `RawRounding` (optional): This is integer number defining how many digits should be left to the right of decimal delimiter after rounding the raw metric. -- `Scaling` (optional): This is integer number defining power of 10 scaling to be applied after rounding the raw metric. This is not to be confused with additional scaling performed by voting dApp, and it is just an optional transformation for scaling reported metric from the `Endpoint` instead (e.g. transforming USD to billions of USD). -- `Rounding` (optional): This is integer number defining how many digits should be left to the right of decimal delimiter after rounding the post-processed metric. -- `Unresolved` (optional): This is numeric value that voters should return for unresolvable price request (defaults to zero if omitted). - -KPI options launcher can also add any arbitrary ancillary data fields as long as they are clearly documented in the linked `Method` document and voters are instructed on how to interpret them for price processing. - -When designing the ancillary data KPI options deployer should be aware that the total size of ancillary data cannot exceed 8192 bytes also accounting for any ancillary data stamping by Optimistic Oracle.

In reality it should be more focused document developed by KPI launch team without going through UMIP approval process.* - -# Rationale - -The technical implementation of this price feed is to allow flexibility for project teams to self-report their own KPI metric. Scalability at the cost of clarity and security trade-off occurs when off-loading the reporting requires externally. - -The user of this UMIP accepts responsibility to provide the information passed through via ancillary data is sufficient to resolve price requests. Suppose the user of the price identifier cannot give enough information for UMA token holders to determine the outcome. In that case, UMA token holders can resolve the price request to zero (unless other non-zero unresolvable state value was provided in the ancillary data). The payout to long KPI option token recipients in unresolvable state would depend on actual financial product library (FPL) used, but for the most common [Linear LSP](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/financial-templates/common/financial-product-libraries/long-short-pair-libraries/LinearLongShortPairFinancialProductLibrary.sol) or [Binary LSP](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/financial-templates/common/financial-product-libraries/long-short-pair-libraries/BinaryOptionLongShortPairFinancialProductLibrary.sol) FPLs that would expire the long KPI option tokens in a worthless state. - -This UMIP also allows the use of KPI measures that may, in some part, rely on information that a trusted party may report. The assumption is that the party reporting the numbers is either trusted or has a vested interest in ensuring the accuracy of the price, but this is not guaranteed. As such, the voter follows i) the methodology outlined in the ancillary data, ii) the fall back alternative outlined in the ancillary data, iii) the most commonly agreed metric to measure a KPI (If and only if this measure is trusted). If none of these outcomes are achieved or the data source is corrupted then the price can be resolved to predefined value (defaulting to zero). - -# Implementation - -1. By default the value of this price identifier is determined by performing a GET request at the `Endpoint` parameter from the ancillary data of price request. Unless the data returned by the `Endpoint` already includes the `Metric` values across all required timestamps the voters should also pass the timestamp parameter to their GET request in the format following the instructions in the linked `Method` document. - - When passing on the timestamp parameter or observing the returned time series data the voters should consider the price request timestamp and any required timestamp rounding as described in the `Interval` parameter from the ancillary data. The voters should take note of the returned `Key` value as tracked raw metric. - - Though the `Method` document might provide alternative request methods (e.g. POST request with data), an alternative data source or predefined timing intervals that should be respected by the verifiers. If `Endpoint`, `Key` or `Interval` parameters are not provided the `Method` document should include precise instructions on how to identify the tracked metric at requested time from returned data. -2. In case the optional `Aggregation` parameter is set in the ancillary data voters should also collect values of tracked raw metric across all timestamps at intervals set in the `Interval` parameter (or interval instructions from the `Method` document) from the start timestamp (as provided in the `Aggregation` parameter) till the price request timestamp and perform any time series processing function described in the `Aggregation` parameter from the ancillary data. As a convenience, KPI options deployer might also provide the expected aggregated value in the `Endpoint` response, but voters are strongly advised to verify this value independently by performing time series processing defined in the `Aggregation` parameter. -3. If any additional ancillary data fields are documented in the linked `Method` document, voters should follow all instructions in this document based on actual additional ancillary data fields passed in the price request. -4. If `RawRounding` parameter from the ancillary data is provided and it is non-negative then round the obtained raw metric (or the result of its aggregation) leaving `RawRounding` number of digits after the decimal delimiter. In case the `RawRounding` parameter is negative then round to the nearest 10 to the power of absolute `RawRounding` value. For example, if `RawRounding` is -6 then one should round the value to the nearest million (10^6). -5. If `Scaling` parameter is passed in the ancillary data then multiply the rounded value of raw metric with 10 to the power of `Scaling`. For example, `Scaling` value of 6 would multiply by 1 million while -3 would effectively divide by 1 thousand. -6. It is recommended to perform any additional post processing in the financial product library so that voters can focus on resolving the raw value of `Metric` in question. In case when the available financial product libraries are missing the required functionality and it is impractical to develop new library KPI options deployer might include additional post processing instructions that voters must perform in the linked `Method` document from the ancillary data. -7. If `Rounding` parameter from the ancillary data is provided then round the processed metric (or raw metric if no post-processing was required) similarly as documented for `RawRounding` in Step 4. In case the `Rounding` parameter is not provided the verifiers should assume its default value of `0`. - -Voters should ensure that their results do not differ from broad market consensus. In particular, voters should verify whether the `Endpoint` source code referenced in the linked `Method` document is consistent with the objective and methodology for calculating particular metric, as well as attempt to run the data service independently and check the accuracy of data provided by the `Endpoint` service. In the event of the `Endpoint` not working or reporting false outcomes voters should follow any fallback instructions found in the linked `Method` document or the optional `Fallback` parameter in the ancillary data. - -Voters should also carefully follow any versioning history to the linked `Method` document and the `Endpoint` service source code. While it is possible that methodology and code could be improved over time in order to clarify any original oversight or fix bugs, voters should ensure that any changes are consistent with the original KPI options program launch objectives. - -In case the ancillary data provided does not comply with the ancillary data specification in this price identifier (to the extent that voters are unable to reasonably figure out what are the intended values of the required parameters) or the linked `Method` document is ambiguous or incomplete with unclear or missing fallback method, the voters should resolve the price request as zero. Though, the optionally passed `Unresolved` parameter in the ancillary data might set any other non-zero fallback value that the voters should return in case of any unresolvable ambiguity and voters should respect this fallback value to the extent it is unambiguously recognizable in the passed ancillary data. - -All resolved price values should be scaled by `1e18` when interacting with contracts directly (e.g. writing scripts, console access or interacting through block explorer). Optimistic Oracle and Voting dApps scales price response automatically so human readable prices should be provided by the users. - -# Security considerations - -This UMIP makes it easier for teams to launch their KPI options without having a pre-approved methodology. This opens the DVM to a potential situation where a price resolution may not be reached since the data is ambiguous or cannot be verified. This concern is addressed by allowing price resolutions for this price identifier to return a predefined value (defaulting to zero). - -An additional security concern is that of manipulation by the controlling entity of the data. Since the creator of a KPI can also be the entity reporting the results, there can be a trusted intermediary involved. To ensure the integrity of the reported figures, each price request will require a link to the methodology of how the feed is being calculated.

As showcased in [this article](https://medium.com/uma-project/uma-raises-2-6mm-in-the-pilot-of-the-range-token-de5be578fa5e), the range token is a new treasury primitive that enables DAOs to access funds and diversify their treasury without directly selling their native tokens. - -Proactively approving these price identifiers will make it easier for development teams and protocol treasuries to create new products using these ERC20 tokens and their price identifiers. - -# Ancillary Data Specifications - -All of the proposed price identifiers can optionally include ancillary data to specify the twap length that these values should be computed using, as well as an optional ohlcPeriod parameter to specify an alternative price interval in seconds. As an example, a price request could specify daily TWAP over 30 days by passing following ancillary data: - -``` -twapLength:2592000,ohlcPeriod:86400 -``` - -When above ancillary data is stored as bytes, the result would be: - -`0x747761704c656e6774683a323539323030302c6f686c63506572696f643a3836343030` - -twapLength and ohlcPeriod should be specified in seconds. If a twapLength key value pair is not present, then voters should first default to the TWAP length(s) specified in `Implementation` or, if there is none, simply calculate the spot price and not a TWAP. If an ohlcPeriod key value pair is not present, voters should default to using 60 second ohlc intervals. - -# POOL - -## Data Specifications - ------------------------------------------ -- Price identifier name: POOLUSD and USDPOOL -- Markets & Pairs: - - POOL/ETH: [Uniswap v2](https://v2.info.uniswap.org/pair/0x85cb0bab616fe88a89a35080516a8928f38b518b) and [SushiSwap](https://analytics.sushi.com/pairs/0x577959c519c24ee6add28ad96d3531bc6878ba34) - - ETH/USD(T): Refer to `ETHUSD` in [UMIP-6](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-6.md) -- Example data providers: Refer to `ETHUSD` in [UMIP-6](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-6.md) -- Cost to use: Refer to `ETHUSD` in [UMIP-6](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-6.md) -- Real-time data update frequency: price is updated with every Ethereum block (~15 seconds per block) -- Historical data update frequency: price is updated with every Ethereum block (~15 seconds per block) - -## Price Feed Implementation - -This price identifier uses the [CryptoWatchPriceFeed](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/CryptoWatchPriceFeed.js), [UniswapPriceFeed](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) and [ExpressionPriceFeed](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/ExpressionPriceFeed.js) with example configuration below: - -``` - POOLUSD: { - type: "expression", - expression: ` - median( (POOL_ETH_UNI * ETHUSD), (POOL_ETH_SUSHI * ETHUSD) ) - `, - lookback: 7200, - minTimeBetweenUpdates: 60, - twapLength: 300, - ohlcPeriod: 60, - customFeeds: { - POOL_ETH_UNI: { - type: "uniswap", - uniswapAddress: "0x85cb0bab616fe88a89a35080516a8928f38b518b", - }, - POOL_ETH_SUSHI: { - type: "uniswap", - uniswapAddress: "0x577959c519c24ee6add28ad96d3531bc6878ba34", - }, - ETHUSD: { - type: "medianizer", - invertPrice: false, - minTimeBetweenUpdates: 60, - medianizedFeeds: [ - { type: "cryptowatch", exchange: "coinbase-pro", pair: "ethusd" }, - { type: "cryptowatch", exchange: "binance", pair: "ethusdt" }, - { type: "cryptowatch", exchange: "kraken", pair: "ethusd" }, - ], - } - }, - }, - USDPOOL: { - type: "expression", - expression: "1 / POOLUSD", - }, -``` - -## Technical Specifications - ------------------------------------------ -- Price identifier name: POOLUSD -- Base Currency: POOL -- Quote Currency: USD -- Rounding: Round to 8 decimal places (ninth decimal place digit >= 5 rounds up and < 5 rounds down) -- Estimated current value of price identifier: 9.18390777 (19 Jul 2021 12:00:00 GMT) ------------------------------------------ -- Price identifier name: USDPOOL -- Base Currency: USD -- Quote Currency: POOL -- Rounding: Round to 8 decimal places (ninth decimal place digit >= 5 rounds up and < 5 rounds down) -- Estimated current value of price identifier: 0.10888611 (19 Jul 2021 12:00:00 GMT) - -## Rationale - -POOL token does not have any recognizable liquidity on CEXs, thus, the only viable alternative currently is to query its pricing from available AMM pools on Uniswap and SushiSwap.

- -# Rationale - -**Why this implementation of the identifier as opposed to other implementation designs?** - -This implementation is due to ibBTC's main sources of liquidity being on Sushiswap. Currently, there are no centralized exchanges with ibBTC listed, and most liquidity will remain on DEXs as it is incentivized. - -**What analysis can you provide on where to get the most robust prices? (Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges)** - -Sushiswap on Ethereum and Polygon networks has the vast majority of ibBTC volume and depth. These should be used over all other sources. - -**What is the potential for the price to be manipulated on the chosen exchanges?** - -The potential risk for this is low. Ethereum and Polygon are reliable networks, and TWAP is used to hedge short term price manipulation. - -**Should the prices have any processing (e.g., TWAP)?** - -A 30 minute TWAP was chosen to help smooth out price changes and give sponsors time to react before becoming undercollateralized. A 30 minute TWAP will also mitigate risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. - -
- -# Implementation - -For all implementations, a block number will need to be used. The block number should be the block that is closest to and before the timestamp that the price request timestamp. - -For ibBTC/BTC and ibBTC/USD TWAP implementations, the TWAP start time should be determined by the latest block 30 minutes before requested timestamp. - -**For ibBTC/BTC and BTC/ibBTC** - - 1.

- -# Security Considerations - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradeable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. - -Collateralization Requirements - All three of these identifiers are very volatile which brings on a higher risk of undercollateralized positions in the case of a massive ibBTC price increase. Minimum collateral ratios should be higher compared with other price identifiers with ~1.5 being the minimum. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness are necessary to prevent market manipulation. diff --git a/research/uma/umips/UMIPs/umip-12.md b/research/uma/umips/UMIPs/umip-12.md deleted file mode 100644 index f207833a..00000000 --- a/research/uma/umips/UMIPs/umip-12.md +++ /dev/null @@ -1,83 +0,0 @@ -## Headers -| UMIP-12 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add PERL as a collateral currency | -| Authors | TJ (tj@perlin.net) | -| Status | Approved | -| Created | August 31, 2020 | - -## Summary (2-5 sentences) -This UMIP will add PERL to the supported collateral currencies into the global whitelist contract, allowing the usage of PERL as collateral currency. - -## Motivation -PERL is the utility token of Perlin Network.

If a value should contain `,` or `:` characters, such value should be enclosed in double quotes. The below listed key parameters will be used to instruct voters how to resolve a given price request for this identifier and request timestamp: -- `base`: Collateral token symbol that should be priced in the submitted price request. -- `baseAddress`: `base` token deployment address on Ethereum network (or any other network if `baseChain` parameter is provided). In case the token is deployed on several networks the user of this price identifier is free to select any network as long as it allows correctly identifying the required base token. -- `baseChain` (optional): ChainID number for the network where base token is deployed. If omitted, Ethereum mainnet would be assumed. -- `quote`: Quote currency symbol in which the `base` token should be priced in -- `quoteDetails`: Additional details to unambiguously identify the quote currency. For cryptocurrencies or fiat currencies this should be the full name of the currency. For fungible tokens it should be the token address on Ethereum network or any other network if accompanied by its ChainID in this parameter. -- `rounding`: This is an integer number defining how many digits should remain to the right of the decimal delimiter after rounding the obtained price. -- `access` (optional): In case data sources in the `configuration` parameter require any special access tokens, this parameter should describe the source for acquiring access and any associated costs, as well as provide the key variable name for the `PRICEFEED_CONFIG` environment variable. -- `fallback`: Data endpoint(s) to use as a fallback mechanism either for the whole `base`/`quote` price request or resolving part of failing data source components (e.g. alternative for Token/ETH when calculating Token/USD). When providing alternative data source components it should be clearly indicated for which part of calculation this fallback source should be used. -- `unresolved` (optional): This is numeric value that voters should return for unresolvable price request (defaults to zero if omitted). -- `configuration`: Price feed configuration formatted as a JSON object that can be used to construct a price feed by [CreatePriceFeed.ts](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/CreatePriceFeed.ts). Please consult UMA documentation covering the selection and configuration of price feed for more details. Also note that default UMA price feed configuration is formatted as JavaScript objects, thus all key names should be enclosed in doublequotes, no comments are allowed, math expressions should be kept in one line and there should be no trailing commas after the last element in JSON. Even though technically proposer/dispute bots would be able to pick up any correctly formatted configuration for available price feed implementation, this price feed configuration should only be used for pricing the `base` token in terms of the `quote` currency. - -When designing the ancillary data TOKEN_PRICE user should be aware that the total size of ancillary data cannot exceed 8192 bytes also accounting for any ancillary data stamping by Optimistic Oracle. This limit would be checked by the LSP creator contract upon the deployment. - -As an example, possible ancillary data for UMA token priced in USD (as specified in UMAUSD in [UMIP-57](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-57.md)) if the user was using TOKEN_PRICE price identifier instead: - -``` -base:UMA,baseAddress:0x04Fa0d235C4abf4BcF4787aF4CF447DE572eF828,quote:USD,quoteDetails:United States Dollar,rounding:6,fallback:"https://www.coingecko.com/en/coins/uma",configuration:{ - "type": "medianizer", - "minTimeBetweenUpdates": 60, - "twapLength": 3600, - "medianizedFeeds": [ - { "type": "cryptowatch", "exchange": "coinbase-pro", "pair": "umausd" }, - { "type": "cryptowatch", "exchange": "binance", "pair": "umausdt" }, - { "type": "cryptowatch", "exchange": "okex", "pair": "umausdt" } - ] - } -``` - -When this ancillary data dictionary is stored as bytes, the result would be (based on [this tool](https://www.rapidtables.com/convert/number/ascii-to-hex.html)): - -``` -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 -``` - -# Rationale - -The technical implementation of this price identifier is to allow flexibility for DAO treasuries to configure their own price feed. Scalability at the cost of security trade-off occurs when off-loading the configuration externally. - -The user of this UMIP accepts the responsibility to provide the information passed through via ancillary data is sufficient to resolve price requests. - -# Implementation - -If ancillary data is correctly configured voters should be able to follow below listed standard steps to resolve the price request using this TOKEN_PRICE identifier: -1. Voters should decode the ancillary data and add the JSON object from the `configuration` parameter as a value (naming its key to be unique) to `defaultConfigs` dictionary object in [DefaultPriceFeedConfigs.ts](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/DefaultPriceFeedConfigs.ts). As an example, choosing `UMAUSD_CUSTOM` as key name from the example in Ancillary Data Specifications section would become: - ``` - const defaultConfigs = { - // Leave other price feed configs here - "UMAUSD_CUSTOM": { - "type": "medianizer", - "minTimeBetweenUpdates": 60, - "twapLength": 3600, - "medianizedFeeds": [ - { "type": "cryptowatch", "exchange": "coinbase-pro", "pair": "umausd" }, - { "type": "cryptowatch", "exchange": "binance", "pair": "umausdt" }, - { "type": "cryptowatch", "exchange": "okex", "pair": "umausdt" } - ] - } - } - ``` -2. In case there are syntax issues with the passed price feed `configuration` voters should attempt to fix it as long as it is unambiguously possible to infer the intended price sources and the calculation logic from this parameter. -3. Prepare the `.env` file in the root of UMA [protocol](https://github.com/UMAprotocol/protocol) repository - it should contain `CUSTOM_NODE_URL` variable pointing to Ethereum node (full archive node is required in case the price feed configuration depends on fetching historical state) and `PRICE_FEED_CONFIG={"lookback":300000}`. `lookback` value of 300000 seconds ensures that prices can be looked up historically during the maximum DVM resolvement period of 72 hours plus added reserve for any required TWAP start period before that. In case `access` parameter is passed on in the ancillary data, voters should also follow the instructions mentioned in this parameter and add any required API key to the `PRICE_FEED_CONFIG` dictionary object. -4. Voters should run the price feed with the selected key name as `--identifier` and requested timestamp as `--time` parameter from the root of UMA [protocol](https://github.com/UMAprotocol/protocol) repository. Following on the example above, the command would be: - ``` - HARDHAT_NETWORK=mainnet node ./packages/scripts/local/getHistoricalPrice.js --network mainnet_mnemonic --identifier UMAUSD_CUSTOM --time 1626984000 - ``` -5. Obtained price feed script value should be rounded leaving `rounding` number of digits after the decimal delimiter. If the next digit after `rounding` equals or is larger than 5, then price should be rounded up, otherwise it should be rounded down. In case the `rounding` parameter is not provided or it is not possible to interpret its value, voters should apply default rounding of 6 digits after the decimal delimiter. -6. Voters should use human judgement on whether the obtained results could be a reasonable estimation for the price of `base` token expressed in terms of `quote` currency and ensure that their results do not differ from broad market consensus. This is meant to be vague as the token-holders are responsible for defining broad market consensus, but some of example issues to check out are: - - Whether the passed price feed `configuration` has any implicit assumptions on the pegging of any trading pairs that do not hold true at the time of the price request that should be corrected accordingly (e.g. a stablecoin has lost its peg to USD). - - Whether an attempted price manipulation can be detected for any of involved trading pairs that should be corrected with additional price period protection (e.g. TWAP). Voters should apply special attention to this in case the value locked in the requesting contract is substantial relative to the liquidity in any of involved trading pair markets. - -In case of misconfiguration or lack of trading activity voters should resolve the price request in fallback mode following the below listed steps: -1. It might be possible that some data sources do not return price data for the requested timestamp due to lack of trading activity or any other technical reason causing the price feed script to fail. In case the price feed `configuration` contains alternative pricing routes for the same asset pair (e.g. when calculating median), voters should reconfigure it without the failing data source and attempt to calculate the requested price from the remaining data sources. -2. In case it is not possible to resolve the requested price either due to lack of trading activity in the specified markets or the `configuration` parameter being misconfigured, voters should attempt to resolve the price from the passed `fallback` parameter: - - Unless other guidance is provided in the `fallback` parameter, voters should assume that the provided endpoint should be queried for the price of `base` expressed in the `quote` currency. - - If `fallback` includes multiple price data endpoints for the same pair, the obtained prices should be medianized. - - If `fallback` includes price data endpoints for multiple pairs, the obtained prices should be combined in attempt to calculate `base` expressed in the `quote` currency. - - In case either `base` or `quote` are interest bearing, vault, liquidity pool or similar tokens that can be converted to their underlying token(s) at the smart contract level, but there are no direct trading markets for obtaining reliable price information, on-chain data should be used to express either `base` or `quote` tokens in terms of their underlying token(s) and then combine it with other pair pricing data from the provided endpoint(s) in the `fallback` parameter to obtain `base` expressed in `quote` currency. -3. In case the fallback mechanism is required, but the provided `fallback` parameter is misconfigured or the provided data endpoints become unavailable: - - Voters should attempt to identify relevant markets for involved trading pairs in order to calculate `base` expressed in units of `quote` using the guidance provided in step 7 above. - - In case the ancillary data passed does not allow to identify the requested `base` token, voters can assume `base` to be the collateral currency of the requesting contract if it allows to unambiguously identify it. Note that currently all financial contracts developed by UMA do have single collateral currency, but this might change in the future and Optimistic Oracle integrations are not restricted to UMA developed financial contracts. - - In case the ancillary data passed does not allow to identify the requested `quote` currency, voters can assume it to be USD (United States Dollar) by default. -4. In case of the lack of any available trading markets at the time of price request (e.g. due to delisting) UMA token holders should resolve the price request to zero. Though, the optionally passed `unresolved` parameter in the ancillary data might set any other non-zero fallback value that the voters should return as a last resort for otherwise unresolvable price request and voters should respect this fallback value to the extent it is unambiguously recognizable in the passed ancillary data. - -# Security considerations - -Anyone deploying a new contract referencing this TOKEN_PRICE identifier should take care to parameterize the contract appropriately to avoid the loss of funds for end users. Particularly, contract deployers should verify that running the price feed script with the passed `configuration` parameter in the ancillary data yields the expected price result before funding the contract. - -It is technically possible to launch a financial contract referencing this TOKEN_PRICE identifier before there is any trading market available by setting the price feed `configuration` parameter that should be expected to work at the time of the price request (e.g. either by guessing CEX trading pair identifier pattern or using deterministic pool addresses for Uniswap pairs). In this case both funders of such financial contracts and end users buying the minted synthetic tokens should accept the risk of loosing part or all of invested funds if there is no public trading market available at the time of price request and UMA voters have to resolve the price request to `unresolved` parameter or zero. - -The same risk scenario described above also applies to any other trading pair that had available markets at the time of deployment, but due to dried up liquidity or delisting there is no public pricing data available at the time of price request for UMA voters to resolve it. Hence, in case this TOKEN_PRICE identifier is used by DAO treasuries to sell derivative financial products backed by native project token, it should be the responsibility of project team to ensure that the native project token is listed with sufficient liquidity at the time of price request so that it can be resolved by UMA voters. End users buying such financial products should also carefully observe the availability of public trading data and evaluate the financial ability of project team to ensure adequate trading activity for its native project token. - -Even though currently this TOKEN_PRICE identifier would most likely be used in LSP contracts one could also use it in EMP contracts if they would support setting custom ancillary data in the future versions. In such scenario end users should take special care to verify the provided price feed configuration. For specific price identifiers UMIP reviewers and UMA voters are providing additional security layer, but for the generic TOKEN_PRICE identifier the responsibility to check price feed configuration is shifted on end users. Hence, before funding such contracts end users should verify that custom ancillary data is consistent, it includes valid and working price feed configuration, risk of sharp movements in price or market manipulation attacks is limited, as well as there is sufficient liquidity in collateral market allowing liquidators to purchase collateral and mint synthetic tokens to liquidate positions before the whole contract gets undercollateralized. - -The users of this TOKEN_PRICE identifier accept that its use can result in loss of funds either due to misconfiguration or external market conditions. Even though UMA holders are incentivized to use the best effort in resolving correct price requests, under no circumstances UMA token holders should be held liable for either not resolving price request or resolving price that differs from broader market consensus. diff --git a/research/uma/umips/UMIPs/umip-122.md b/research/uma/umips/UMIPs/umip-122.md deleted file mode 100644 index 39417a72..00000000 --- a/research/uma/umips/UMIPs/umip-122.md +++ /dev/null @@ -1,68 +0,0 @@ -# Headers - -| | | -|----------------|-------------------------------------------------------------------------------------------------------| -| UMIP Title | Add Polygon `DerivativeFactory` as `Creator` in DVM registry | -| Authors | Iliyan Iliev (iliyan.iliev@jarvis.exchange) | -| Status | Approved | -| Created | 28/07/2021 | -| Discourse link | https://discourse.umaproject.org/t/register-polygon-derivativefactory-as-creator-in-dvm-registry/1267 | - -# Summary - - -Reminder: Synthereum is a protocol to issue multi-collateralized synthetic fiat assets against liquidity pools.

This combined with other linked projects and activities such as farming could potentially create a low-gas cost financial infrastructure for our FX synthetic assets. - -# Technical Specification - -### Breakdown on the whole deployment process of a new derivative: - -For reference on the deployment process you can check [[UMIP-101](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-101.md) as the process remains the same with the current version deployed on Polygon. - -### Modifications done: - -The only modification done since the previous approved version of the `DerivativeFatory.sol` is the update from pragma solidity version 0.6.12 to 0.8.4. - -Apart from that the only modifications done, not concerning the `DerivativeFactory.sol` were to integrate UMA Bridge in order to access the DVM from Polygon. - -The previous version modifications can be seen in [UMIP-101](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-101.md). - - -# List of deployed contracts: - -1.

As swap fees are a direct proxy for volume/volatility, there are many parties that would benefit if such a product existed. Two groups who would likely balance short and long interest, namely: - -**Potential short party**: Market makers, miners, MEV searchers, Sushiswap and xSushi holders (assuming sufficient liquidity) could hedge revenues by shorting this synthetic if they believe that volume is likely to decline as all parties have revenues correlated to volume. - -**Potential long party**: Speculators can take leveraged bets on the direction of swap fees/volume/volatility. The leverage is implicit as taking bets on the xSushi yield through this synthetic does not require the capital intensive depositing of Sushi in return for xSushi. - -# Data Specifications: - -All relevant price data is computed using information that can be found directly on the blockchain using an archive node. -* Price identifier name: `XSUSHI_APY` -* Example price providers: The relevant data can be obtained on-chain using an archive node: - * Alchemy (node) offers a free 25,000,000 compute units / month with archive node capability -* This information is also available on The Graph with the exact timestamps needed (UTC 00:00:00) -* Real-time price update frequency: Updated every day -* Historical price update frequency: Updated every day - -# Technical Specifications: - -* Price identifier name: `XSUSHI_APY` (5% expressed as 5 i.e not decimal format) -* Base Currency: XSUSHI APY -* Quote Currency: N/A -* Rounding: Round to 4 decimal places (fifth decimal place digit >= 5 rounds up and < 5 rounds down) - -# Rationale: - -xSushi yield was specifically chosen as it is much easier/cheaper to distort volume/swap fees in a single pool than across an entire AMM (current TVL of sushiswap is >$3bn at the time of writing). - -Another core consideration that led to using xSushi APY is that 0.05% of every swap fee of 0.3% is redirected to xSushi stakers. Meaning to generate $1 of fees for xSushi holders through trading, a trader will have to pay $6 in swap fees ($6 x 0.05%/0.3% = $1) significantly raising the cost of manipulation. - -Both methods above significantly reduce potential price identifier manipulation. - -# Price Feed Implementation - -The accounting methodology for xSushi is fortunately very simple. The Sushi generated from protocol revenue is deposited into a smart contract which all xSushi holders have a proportional share in. The ratio in which xSushi can be redeemed for Sushi is calculated by dividing the ever increasing Sushi balance in the xSushi smart contract by the number of xSushi tokens in circulation. - -The `XSUSHI_APY` price would require the creation of a new price feed.

To do this, voters should use the open price of the OHLC period that the price request timestamp falls in.

Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as a official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation). A reference TraderMade implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/TraderMadePriceFeed.ts). - -Our team has adjusted the original Liquidation and Dispute bots in order to fit the interfaces of our protocol.

There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes.

Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. diff --git a/research/uma/umips/UMIPs/umip-128.md b/research/uma/umips/UMIPs/umip-128.md deleted file mode 100644 index b89235ef..00000000 --- a/research/uma/umips/UMIPs/umip-128.md +++ /dev/null @@ -1,42 +0,0 @@ -## Headers -UMIP-128 - -- UMIP title: Add DFX as a Polygon collateral currency -- Author: Chandler (chandler@umaproject.org) -- Status: Approved -- Created: 10 September 2021 - -## Summary (2-5 sentences) - -This UMIP proposes adding **DFX** for use as collateral in UMA contracts for the Polygon Network.

Divide by 1000, and then round to 6 decimals to arrive at the final price. - - -**Example** - -If the timestamp requested was `1619222400` then: - -* We would need to identify all `PunkBought` events from `1619222400 - 30 days -> 1616630400` to `1619222400` -* Imagine that we had 5 `PunkBought` events with (`ts`, `punk_id`, `eth`) pairs of `[(1616630450, 1000, 20), (1616631450, 5000, 30), (1616631550, 5000, 35), (1618631550, 6000, 22), (1618632550, 9999, 15)]`. -* We would need to check what function generated each `PunkBought` event. Suppose they were all generated by `buyPunk`, then the prices we would use to compute the median would be `[20, 35, 22, 15]` -* There are an even number of values, so there's no "median value" in the data -- Thus we find the number between the two values closest to the median `[20, 22]` to get a price of `21` -* Divide by `1000` to get a price of `0.021` - -### Before Expiry - -When a price request that relies on this price identifier is made, the following process should be followed: - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp - TWAP period (2 hours). -3. A single Uniswap/Sushiswap price is defined for each timestamp as the price that the ETH/uPUNK pool returns at the end of the latest block whose timestamp is less than or equal to the timestamp that is queried for. -4.

An individual who owns 400 CryptoPunks and traded them amongst their own accounts at prices near zero could corrupt the price by driving it to zero after having minted and sold the tokens at a high price. - -One benefit to using an oracle with human intervention is that voters could recognize this type of price manipulation and there are other viable proxies for the expected price of a CryptoPunk. For example, if voters felt like there was price manipulation, they could choose to settle the contract at the current market price of `PUNKBASIC` or other - -The other main concern is if there were just insufficient CryptoPunk trades being made. If there were only 1-2 trades happening every 30 days, this index becomes much less useful because there's less information contained in its price. - -### Before Expiry - -The main concerns of the TWAP price are: - -1. **Token price manipulation**: If the Uniswap pool is not sufficiently liquid, then attackers could try to drive down the Uniswap price and withdraw more collateral than intended. Most DeFi attacks have been done using flash loans, but flash loans would be ineffective since the price is measured at the end of each block. Collateralizaton based on the TWAP price would make it more capital intensive (and thus risky) to target the token price in this way. -2. **TWAP mismatch**: If the price of the token rises quickly then there would become a mismatch between the market price and the TWAP price. This might allow sponsers to mint tokens with less collateral than what they could sell them for on the market. Reasonable levels of collateralizaton requirements and the 2 hour "liveness period" help combat this concern. - -Both of these concerns are originally discussed in [UMIP 22](./umip-22.md) diff --git a/research/uma/umips/UMIPs/umip-131.md b/research/uma/umips/UMIPs/umip-131.md deleted file mode 100644 index e65483db..00000000 --- a/research/uma/umips/UMIPs/umip-131.md +++ /dev/null @@ -1,69 +0,0 @@ -## Headers -UMIP-131 - -- UMIP title: Add miMATIC, VOL, BIFI, ICE, IRON and IF as supported collateral currencies -- Author: Chandler (chandler@umaproject.org) -- Status: Approved -- Created: 13 September 2021 - - -## Summary (2-5 sentences) - -This UMIP proposes adding **miMATIC**, **VOL**, **BIFI**, **ICE**, **IRON** and **IF** for use as collateral in UMA contracts. - -## Motivation - -The addition of this collateral currency offers additional functionality to the UMA protocol and increases the range of contracts that can be built. - -miMATIC also known as MAI is a soft pegged stablecoin that is backed by other assets in the Polygon network. - -## Technical Specification - -To accomplish this upgrade, the following changes needs to be added to the collateral currency whitelist introduced in UMIP-8. - -## Ethereum -### VOL token -- The **VOL** Ethereum [token address](https://etherscan.io/token/0x5166e09628b696285e3a151e84fb977736a83575): 0x5166e09628b696285e3a151e84fb977736a83575 -- A final fee of **1200 VOL** needs to be added in the Store contract. - -### IF (Impossible Finance) - - The **IF** Ethereum [token address](https://etherscan.io/token/0xb0e1fc65c1a741b4662b813eb787d369b8614af1): 0xb0e1fc65c1a741b4662b813eb787d369b8614af1 - - A final fee of **250 IF** needs to be added in the Store contract. - -## Polygon -### miMATIC token -- The **miMATIC** Polygon [token address](https://polygonscan.com/token/0xa3fa99a148fa48d14ed51d610c367c61876997f1): 0xa3fa99a148fa48d14ed51d610c367c61876997f1 -- A final fee of **400 MAI** needs to be added in the Store contract. - -### BIFI token -- The **BIFI** Polygon [token address](https://polygonscan.com/token/0xfbdd194376de19a88118e84e279b977f165d01b8): 0xfbdd194376de19a88118e84e279b977f165d01b8 -- A final fee of **0.5 BIFI** needs to be added in the Store contract. - -### ICE token (Iron Finance) -- The **ICE** Polygon [token address](https://polygonscan.com/token/0x4A81f8796e0c6Ad4877A51C86693B0dE8093F2ef): 0x4A81f8796e0c6Ad4877A51C86693B0dE8093F2ef -- A final fee of **23 000 ICE** needs to be added in the Store contract. - -### IRON stablecoin - - The **IRON** Polygon [token address](https://polygonscan.com/token/0xD86b5923F3AD7b585eD81B448170ae026c65ae9a): 0xD86b5923F3AD7b585eD81B448170ae026c65ae9a - - A final fee of **400 IRON** needs to be added in the Store contract. - -## Rationale - -This store fee was chosen as it is approximately equivalent to $400 in line with other collateral currencies as determined by assuming that the MIA and IRON tokens will hold its peg to $1 per token or by using CoinMarketCap and CoinGecko prices. - -## Implementation - - -This change has no implementations other than the aforementioned governor transactions - -## Security considerations - -Adding a collateral currency introduces a level of risk into the UMA Ecosystem.

The idea is to have smart contract security experts assess/price protocol coverage, then get paid based on the performance of the protocols (no hacks = large payout, large hack = no payout). Protocols who want coverage will pay Sherlock monthly premiums, and in return, Sherlock will use it’s staking pool to repay hacks at protocols. Sherlock is doing a guarded launch with $30M in staking pool funds and writing coverage for up to $10M per protocol. More details can be found here. - -Other exploit protection protocols rely on their tokenholders to decide whether claims should be paid out or not. Sherlock wants to do better and would like to use UMA’s Data Verification Mechanism as the final escalation to decide on claims payouts. This would help coverage buyers feel more comfortable that they have access to an unbiased party’s decision on a claim. - -For context, Sherlock agrees on coverage terms with every protocol. An example can be seen here (TBA). These terms will be broadly the same across all protocols but there may be extra language added for protocol-specific exploit risks. - -In the event of a potential exploit, Sherlock’s security team will work with the protocol to determine the nature of a hack. If the protocol believes they experienced an exploit that should be covered by Sherlock, the protocol will submit the block range of the exploit and the amount to be reimbursed by Sherlock. Next, Sherlock’s claims committee (made up of reputable security experts associated with Sherlock such as [John Mardlin](https://twitter.com/maurelian_), [Mariano Conti](https://twitter.com/nanexcool), and [Rajeev Gopalakrishna](https://twitter.com/0xRajeev)) will work to evaluate the nature of the potential exploit and then map the exploit to the coverage terms agreed to with that protocol. The committee will then decide whether to pay out the claim. If the committee decides not to pay out the claim, the protocol has the option to stake a minimum dollar amount ($50k for example) and escalate the claim to the UMA Data Verification Mechanism. The UMA tokenholders would then use information provided by the protocol, the claims committee, and importantly, security expert not associated with Sherlock, to decide whether the claim should be paid out or not. - -Relying on UMA’s DVM for claims decisions will significantly increase the value of on-chain exploit protection mechanisms in the eyes of protocols and end users. One of the biggest hurdles to adoption of coverage is the biased nature of claims processes. Sherlock believes that the involvement of UMA’s DVM will make exploit protection protocols more trustworthy and further normalize adoption of coverage by protocols and end users alike. By adding this product, UMA can blaze a trail that contributes to the safety of DeFi. Sherlock would love to set a precedent with UMA for how exploit claims disputes should be resolved on-chain. - -## Ancillary Data Specifications - -``` -Metric:Sherlock exploit claim arbitration, -Protocol:, -ChainId:, -Value:, -StartBlock:, -Resources:, -CoverageAgreement: -``` - -Example: -``` -Metric:Sherlock exploit claim arbitration, -Protocol:UMA Protocol, -ChainId:1, -Value:1000000, -StartBlock:13207345, -CoverageAgreement:Link to protocol specific coverage agreement with Sherlock -``` - -For guidance on how to structure ancillary data correctly, refer [here](https://docs.umaproject.org/uma-tokenholders/guidance-on-adding-price-identifiers#ancillary-data-specification). - -## Rationale and usage - -The framing of the price identifier puts the responsibility on the protocol to specify the correct blocktime, blockchain, and payout amount in order to receive a payout. If any of the information is not accurate, a payout will not occur. This is mitigated by the idea that a protocol will get up to 3 chances to correctly input the data in order to successfully trigger a payout. - -Because the potential request space is broad, it is possible that voters will not be able to arrive at a definitive result. In this case, the default return value should be “unresolvable” (or 0.5), which likely will also result in no payout from Sherlock to the claimer. This places the onus on the protocol to provide clear evidence that an exploit occurred. Practically from the Sherlock side, a returned value of 0.5 or 0 will make no difference, as neither will change the committee's "no payout" outcome. - -It is low risk for UMA voters to return a value of 0.5, as it is likely that this will result in a resubmission of the price request by the claiming protocol once they have have accumulated more concrete evidence of their claim. If a claim is paid out in error, there is little recourse for Sherlock at that point, so it seems reasonable that a protocol should have to prove that a payout occurred and that the default should be “no action”, meaning a payout is not enacted. - -## Implementation - -1. Voters should decode the ancillary data and identify the protocol, chain, start block, dollar value of claim in question and any additional resources provided. -2. Because the protocol making the claim will likely be the party constructing the ancillary data and submitting a price request, voters should heavily rely on checking external resources for additional context. The Sherlock Coverage Terms Agreement should always be referenced. Additionally the Protocol's original claim as well as the Sherlock Claims Committee's original claims decision will likely always be published and should be referenced. Sherlock's Coverage Agreement details the exact types of exploits that Sherlock covers, and these should be the only exploits that are considered in arbitration. More information is provided in the `Additional Resources` section below. -3. Voters should return a value of `1` if they determine that: - 1. There was an exploit for the `Protocol` specified. - 2. The exploit type is covered by Sherlock's Coverage Agreement. - 3. The exploit happened as part of the `StartBlock` specified in ancillary data. - 4. The total USD value lost in the exploit is greater than or equal to the USD `Value` within ancillary data. -4. If voters can confidently identify that one of the above is not correct, they should return a value of `0`. -5. If voters cannot confidently assess one of the criterion above, they should return a value of `0.5` (cannot be resolved). - -## Additional Resources -While the coverage agreement document between Sherlock and the protocol in question will serve as the canonical guideline as to whether an exploit falls under coverage or not, it is non-trivial to determine whether an exploit occurred, and how that exploit maps to the coverage agreement. - -Outside of the coverage agreement, UMA tokenholders should rely on 3 sources of information when making their decision: -1) The interpretation of the exploit and coverage agreement by the Sherlock claims committee and other persons associated with Sherlock. -2) The interpretation of the exploit and coverage agreement by the protocol in question. -3) Most important, the interpretation of the exploit and coverage agreement by third party security experts. - -While information in 1) and 2) should be readily available (both parties will be motivated to explain their interpretation), we can reasonably expect 3) to be readily available as well based on historical public interest in protocol exploits and past articles produced. - -Sources of 3) could be [rekt.news](https://twitter.com/RektHQ), [Mudit Gupta](https://twitter.com/Mudit__Gupta), [Kelvin Fichter](https://twitter.com/kelvinfichter), [Igor Igamberdiev](https://twitter.com/FrankResearcher), as well as audit firms such as [PeckShield](https://twitter.com/peckshield) as long as the parties don’t have material connection to either Sherlock or the protocol in question. - -## Security Considerations - -It should be noted that this price identifier is objectively complex and broad and will likely require a large amount of active participation from UMA voters to correctly analyze and resolve these requests. UMA voters should not be expected to be security experts, and therefore do not accept any liability from potential claims from either the claiming protocol or Sherlock. UMA voters should only be expected to act as an impartial jury; their responsibility is to synthesize information from ancillary data, `Additional Resources`, Sherlock's coverage terms and ad hoc information provided by Sherlock and the claiming protocol during arbitration, but not to perform complete security analysis themselves. - -There are also several mitigating processes built into the Sherlock system as well as the UMA voting system. As noted previously, claiming protocols will have up to 3 total chances to submit claims and go to a DVM vote. This should allow for comprehensive information gathering and analysis, and will allow UMA voters to default to an "unresolvable" return value unless clear supporting evidence is provided either to support or contradict a claim. - -The DVM voting system also allows for a multi-day discussion and information gathering process. Because of this reason, it seems acceptable that the potential price request space for this identifier is broad and potentially subjective. Both the claiming protocol, as well as Sherlock's security committee will have the opportunity to provide supporting evidence and advocate for their case. It is recommended that both parties be active in UMA's #voting [Discord channel](https://discord.gg/YE4h2YAb), as this is where most UMA voting discussion occurs. diff --git a/research/uma/umips/UMIPs/umip-133.md b/research/uma/umips/UMIPs/umip-133.md deleted file mode 100644 index 80a52c58..00000000 --- a/research/uma/umips/UMIPs/umip-133.md +++ /dev/null @@ -1,47 +0,0 @@ -## Headers -UMIP-133 - -- UMIP title: Add PERP, GRO and POOL as collateral currency -- Author: Chandler (chandler@umaproject.org) -- Status: Approved -- Created: 28 September 2021 - -## Summary (2-5 sentences) - -This UMIP proposes adding **PERP**, **POOL** and **GRO** for use as collateral in UMA contracts. - -## Motivation - -The addition of this collateral currency offers additional functionality to the UMA protocol and increases the range of contracts that can be built. - -## Technical Specification - -To accomplish this upgrade, the following needs to be added to the collateral currency whitelist introduced in UMIP-8. - -### PERP -- The **PERP** Ethereum [token address](https://etherscan.io/token/0xbc396689893d065f41bc2c6ecbee5e0085233447): 0xbc396689893d065f41bc2c6ecbee5e0085233447 -- A final fee of **35 PERP tokens** needs to be added in the Store contract. - -### GRO -- The **GRO** Ethereum [token address](https://etherscan.io/address/0x3ec8798b81485a254928b70cda1cf0a2bb0b74d7): 0x3ec8798b81485a254928b70cda1cf0a2bb0b74d7 -- A final fee of **35 GRO tokens** needs to be added in the Store contract. - -### POOL -- The **POOL** Polygon [token address](https://polygonscan.com/address/0x25788a1a171ec66da6502f9975a15b609ff54cf6): 0x25788a1a171ec66da6502f9975a15b609ff54cf6 -- A final fee of **45 POOL tokens** needs to be added in the Store contract. -## Rationale - -This store fee was chosen as it is approximately equivalent to $400 in line with other collateral currencies as determined by using the average price observed on Coinmarketcap. - -## Implementation - - -This change has no implementations other than the aforementioned governor transactions - -## Security considerations - -Adding a collateral currency introduces a level of risk into the UMA Ecosystem.

If no event exists with that hash, the relay is invalid. - -In the same event, the voter should see a `depositData` field containing `DepositData` struct. The `DepositData` struct should contain a `chainId` field. This field should be used to call `depositContracts(chainId)` on the `BridgeAdmin` contract (called at the latest block number at or before timestamp from `quoteTimestamp` field in the `DepositData` struct) and take the `depositContract` value in the struct (first element). This should be the deposit contract address on the chain specified by the chainId (arbitrum or optimism). The voter should query this contract for the [FundsDeposited](https://github.com/UMAprotocol/protocol/blob/b588e83ca548a2a0d59b36f02ec9800afce28dec/packages/core/contracts-ovm/insured-bridge/implementation/BridgeDepositBox.sol#L73-L84) event to verify that its fields match the corresponding `DepositData` struct fields on mainnet exactly. If there is any difference, the relay is invalid. - -In the `RelayData` struct in the DepositRelayed event queried earlier, there is a field called `realizedLpFeePct`. Note: the `RelayData` struct is called `relay` in the event, and to decode the `realizedFeePct` field, one may need to decode with web3.js/ethers and extract the 4th field, since structs are sommetimes decoded as tuples rather than a struct with named fields. This field is specifified by the relayer and needs to be computed using the `quoteTimestamp` specified in the `depositData`. The algorithm for computing the `realizedLpFeePct` is specified below where: - -* $X$ denotes the size of a particular transaction someone is seeking to bridge -* $0 \leq U_t \leq 1$ denotes the utilization of the liquidity providers' capital prior to the transaction, i.e. the amount of the liquidity providers' capital that is in use prior to the current transaction -* $0 \leq \hat{U}_t \leq 1$ denotes the utilization of the liquidity providers' capital after to the transaction, i.e. the amount of the liquidity providers' capital that would be in use if the user chose to execute their transaction -* $\bar{U}$ denotes the "kink utilization" where the slope on the interest rate changes -* $R_0, R_1, R_2$ denotes the parameters governing the interest rate model slopes: - * $R_0$ is the interest rate that would be charged at 0% utilization - * $R_0 + R_1$ is the interest rate that would be charged at $\bar{U}\%25$ utilization - * $R_0 + R_1 + R_2$ is the interest rate that would be charged at 100% utilization - -An interest rate at any given amount of utilization would be given by the following equation: - -$R(U_t) = R_0 + \frac{\min(\bar{U}, U_t)}{\bar{U}} R_1 + \frac{\max(0, U_t - \bar{U})}{1 - \bar{U}} R_2$ - -In our case for a loan, we must integrate over a range of utilizations because each dollar of the loan pushes up the interest rate for the next dollar of the loan. This effect is captured using an integral: - -$R^a_t = \int_{U_t}^{\hat{U}_t} R(u) du$ - -To get the true rate charged on these loans, we need to de-annualize it to get the percentage: - -$R^w_t = \min \left( (1 + R^a_t)^{\frac{1}{52}} - 1, 1 \right)$ - -which bounds the LP fee to being less than or equal to 100% of the transfer amount. - -$U_t$ can be fetched on-chain by calling `liquidityUtilizationCurrent` method on the `BridgePool` contract at the latest available block number at or before the `quoteTimestamp`. $\hat{U}_t$ can be fetched by calling `liquidityUtilizationPostRelay` method on the `BridgePool` contract at the same block number passing the `amount` field from the `DepositData` struct as `relayedAmount` parameter. Normally the `BridgePool` contract for calling these methods should be the same as the `requester`, but in the unlikely scenario when `BridgePool` gets migrated with pending deposits on L2 one should calculate the utilization ratio on the `BridgePool` contract that was active at the time of `quoteTimestamp`. In order to identify the previous `BridgePool` one should look up the last `WhitelistToken` event emitted by the deposit contract on L2 before the relayed transaction's `quoteTimestamp` and use the address from event's `bridgePool` field. - -Since the notion of `block.timestamp` might be different on other L2 chains compared to main ethereum L1 EVM, deposit contracts on L2 allow setting the `quoteTimestamp` within 10 minute range from current time. In order to deterministically calculate LP fees based on pool utilization ratio the relayer should wait until L1 block timestamp reaches the `quoteTimestamp`. Any relayed transaction that is mined with earlier block timestamp than `quoteTimestamp` field from `DepositData` struct in the `DepositRelayed` event should be invalid. - -Please see the example [implementation](https://github.com/UMAprotocol/protocol/blob/b588e83ca548a2a0d59b36f02ec9800afce28dec/packages/sdk/src/across/feeCalculator.ts#L78-L82)) for more details. - -The rate model parameters used for the above computation should be fetched on-chain from the `RateModelStore` contract deployed on mainnet at [0xd18fFeb5fdd1F2e122251eA7Bf357D8Af0B60B50](https://etherscan.io/address/0xd18fFeb5fdd1F2e122251eA7Bf357D8Af0B60B50) and governed by Across protocol [multi-signature account](https://etherscan.io/address/0xb524735356985d2f267fa010d681f061dff03715). Rate model parameters should be fetched by calling `l1TokenRateModels` method on the `RateModelStore` contract passing `l1Token` address as its argument at the block whose timestamp corresponds or is the latest available relative to the `quoteTimestamp` field. - -The call to `l1TokenRateModels` should return a stringified JSON object containing the following key-value pairs: -* `UBar` corresponds to the $\bar{U}$ rate model parameter; -* `R0`, `R1` and `R2` correspond to $R_0$, $R_1$ and $R_2$ parameters respectively. - -Rate model parameter values obtained above should be scaled down by 18 decimals. - -In case the call to `l1TokenRateModels` returns anything that cannot be parsed to the exact key-value pairs mentioned above (e.g. missing or extra parameter included) the relay should be considered invalid. - -If the algorithm above doesn't produce a matching `realizedLPFeePct` (after floor rounding the result expressed as decimal to 18 decimals), the relay is invalid. If the token is not listed in the table above, the relay is invalid. - -If the relay is invalid, the price should be `0`. If the relay is valid, it should be `1`.

Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not, the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different from the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as an official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation). A reference TraderMade implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/TraderMadePriceFeed.ts). - -Our team has adjusted the original Liquidation and Dispute bots in order to fit the interfaces of our protocol. You can find our versions of the Liquidator and Dispute bots on the following GitLab links: - -- [Liquidator Bot](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jrv_bot/packages/liquidator/test) -- [Dispute Bot](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jrv_bot/packages/disputer/test) - -TraderMade is provided as an accessible source to query for this data, but ultimately how one queries for these rates should be varied and determined by the voter to ensure that there is no central point of failure. - -In the case of a TraderMade outage voters can turn to any other available price feed API or a broker API, as the price feeds for the forementioned financial assets does not differ much between different providers. There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes. For this case, we provide options for additional price feed providers that voters could utilize. - -## Additional price feed providers - -### FXMarketAPI - -Documentation for the API can be found [here](https://fxmarketapi.com/documentation#live_rates). - -- Live price feed data -- Historical prices based on date and time -- Registration is free and provides 500 free requests -- Paid plans available -- OHLC request can be used to grab the last closing price before a weekend or a non-working day - -Example requests: - -- Live Rate for AUDUSD: `https://fxmarketapi.com/apiliveapi_key=api_key¤cy=AUDUSD` -- OHLC for a certain date on a currency pair: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=AUDUSD&date=2020-12-23&format=ohlc` -- Request for AUDUSD price at a certain date and time: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=AUDUSD&date=2020-12-23-15:50` - -### FCS API - -Documentation for the API can be found [here](https://fcsapi.com/document/forex-api). - -- 500 API Calls with Free Plan -- Live price data accessible with Free Plan - Updated every 60 seconds or less -- Historical data accessible with the Basic Paid Plan - 10$ per month - -Example requests: - -- Live Rate for AUD/USD: `https://fcsapi.com/api-v3/forex/latest?symbol=AUD/USD&access_key=api_key` -- Historical price for a certain date for AUD/USD - gives back the OHLC: `https://fcsapi.com/api-v3/forex/history?symbol=AUD/USD&period=1D&from=2020-12-23&to=2020-12-24&access_key=api_key` -- Price of AUD/USD between certain dates and times - gives a breakdown on the price each 1 minute between 12:00 and 12:30: `https://fcsapi.com/api-v3/forex/history?symbol=AUD/USD&period=1M&from=2020-12-23T12:00&to=2020-12-23T12:30&access_key=api_key` - -## Security considerations - -Adding this new identifier by itself poses a little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of AUDUSD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap on AUD/USD, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidations and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. diff --git a/research/uma/umips/UMIPs/umip-14.md b/research/uma/umips/UMIPs/umip-14.md deleted file mode 100644 index e588ddeb..00000000 --- a/research/uma/umips/UMIPs/umip-14.md +++ /dev/null @@ -1,63 +0,0 @@ -## Headers -| UMIP-14 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Approve Updated EMP Financial Contract Template | -| Authors | Nick Pai (nick@umaproject.org) | -| Status | Approved | -| Created | September 16, 2020 | - -## Summary -This UMIP will have the effect of introducing an upgraded expiring financial contract template that: -1. Updates the `ExpiringMultiPartyCreator` factory contract's restrictions on liveness periods and the expiration timestamp. -2. Relaxes `ExpiringMultiParty`'s token creation collateralization requirements. -3. Adds additional power for under-funded liquidators to deter malicious sponsors with large position sizes. -4. Supports collateral currencies that accumulate interest, like [aTokens](https://docs.aave.com/developers/developing-on-aave/the-protocol/atokens#redirectintereststream) which redirect interest to a target address. -5. Enables redemptions post-expiry and most importantly, during the two day expiry price resolution pricess. - -## Motivation & Rationale - -This UMIP was motivated by a combination of user comments and economic attack surface considerations. - -## Technical Specification -To accomplish this upgrade, a new financial contract template must be deployed. - -After deployment, this new `ExpiringMutltiPartyCreator` contract should be approved as a ContractCreator in the Registry. - -Note: the voters only vote for the approval -- the deployment has no effect on the protocol until added as a ContractCreator. - -**The specific changes in detail comprise:** - -1. Updating EMPCreator restructions: - - The EMPCreator should explicitly enforce that expiration times are in the future. The EMP itself already enforces this, but the creator's `deploy` function should revert earlier if the deployer attempts to pass an expiration time in the past. - - This update also places a hard-cap on the liquidation liveness and withdrawal liveness parameters. Currently, the applied changes allow setting arbitrarily large values, which could cause undesired reverts due to overflows. - -2. Relaxing token creation collateralization requirements: - - The UMA price oracle requires a novel mechanism to guarantee user collateralization despite not having direct access to the real-time price of the collateral. The Global Collateralization Ratio (GCR) is used as a substitute, since it would be an overestimate of the required value under some reasonable economic assumptions. Whenever a new position is opened, the user is required to match this GCR with the corresponding new collateral. - - However, this may be unnecessarily restrictive, since the collateralization ratio of each change in the position is not individually relevant. Users have criticized, rightfully, the bad UX requiring an over-collateralized sponsor to always create new tokens in a ratio above the GCR, even if their existing position is already well above the GCR. **This update relaxes the requirement to ensure that either the final user position matches the GCR, or the new collateral and minted tokens match the GCR (as before)**. - -3. Empowering under-funded liquidators: - - When a withdrawal that would put a position below the Global Collateralization Ratio is requested, liquidators have a time window to liquidate the position if the withdrawal is invalid. However, if the position is sufficiently large, it may be difficult for liquidators to (collectively) obtain enough synthetic tokens within the allotted time window. - - This update resets the withdrawal time window whenever a partial liquidation that is sufficiently large occurs within the window. It should be noted that although this mechanism can be used to delay valid withdrawals, potentially until expiration, it does not remove the usual penalty associated with false liquidations, which would have to be paid for every delaying transaction. - -4. Supporting new collateral currency types: - - Developers want to be able to deploy EMP's collataralized by aTokens. A new `trimExcess()` method is added to the EMP so that aToken interest can be redirected to an external contract. - -5. Enabling redemptions post-expiry: - - After an EMP contract expires, collateral is locked within the contract while an expiry price is resolved by the UMA oracle voters. This places extra price risk on sponsors. - - This pull request removes the time restriction on the `redeem` function so it can be called even after the contract expires and enables them to redeem a proportional amount of collateral to their synthetic tokens burned. It also allows the `cancelWithdrawal` function to be called after expiration, so that a pending slow withdrawal will not stall the token redemption. - -## Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/core/contracts/financial-templates/expiring-multiparty). The directory contains both the [implementation](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/expiring-multiparty/ExpiringMultiParty.sol) of the `ExpiringMultiParty` template and the [deployer contract](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/expiring-multiparty/ExpiringMultiPartyCreator.sol) that will be registered with the DVM to allow users to deploy their own `ExpiringMultiParty` contract. - -The following PR's implemented the changes described and numbered in the Summary and Motivation sections: -1.

SPACs have only a limited period during which they may consummate a Business Combination, generally not exceeding 24 months. A SPAC generally focuses upon one industry or sector, but may maintain flexibility to engage in transactions in other industries or sectors if necessary or appropriate. More information about SPACs can be found [here](https://spac.guide/spacbasics/) and [here](https://www.spacanalytics.com/).

-`A good way to capitalize on such momentum growth without having to analyze hundreds of SPACs is to take advantage of the movement of the index value that includes stocks of the most active SPACs.`
- -The selection of **10** stocks of the most active SPACs included in the basket of the proposed uSPAC10 index is made according to [SPAC Analytics Top Performing SPACs](https://www.spacanalytics.com/).
->SPAC Analytics is the leading provider of SPAC data and research to portfolio managers and investment banks since 2007. - -These underlying assets are traded on the NYSE and NASDAQ, but reliable sources of quotations are either paid or provide data with a delay.
-We suggest using the ["Stock Data – Rapidapi.com"](https://rapidapi.com/principalapis/api/stock-data-yahoo-finance-alternative/) API as the main source of quotes, which has both free and paid tariff plans, and also provides historical price data. - ->Stock Data – Rapidapi.com is a decision for retrieving real time stock data. Alternative to the Yahoo Finance API. Rapidapi.com Finance APIs allow end-users a variety of service options for their accounts as well as to stay current on events and news that impact their portfolios and financial security. For example, a finance API could remotely connect them to their bank account to initiate deposits, transfers, or other transactions. Other financial APIs include stock market news and trading platforms, cryptocurrency markets, and more. A financial API provides a secure link from a consumer to the databases and transactional servers of the institutions with which they do business. Application programming interfaces, or APIs, are the digital links between data providers and end-users. In the financial sector, security is essential as sensitive information is transferred in real-time, so only the most robust protocols are utilized to protect the data transmitted on both ends. - -Underlying stocks are traded during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. - -## IMPLEMENTATION -### Price Identifier -The index basket is formed by including the first 10 stocks from the Top Performing SPACs table from the website [SPACanalytics.com](https://www.spacanalytics.com/) on 30.06.2022. -The list of stocks included in the index basket are: -|N|TICKER|MARKET| -|:--:|:------:|:--------:| -| 1|DWAC|NASDAQ| -| 2|IRDM|NASDAQ| -| 3|MP |NYSE | -| 4|PRIM|NASDAQ| -| 5|WSC |NASDAQ| -| 6|SMPL|NASDAQ| -| 7|TGLS|NASDAQ| -| 8|CERE|NASDAQ| -| 9|KW |NYSE | -|10|HPK |NASDAQ| -

-- N - number of shares in index. **N = 10**
-- K - Correction factor, used to smooth the index values when the basket is changed. For the current index bucket **K = 0,95951**. The value of K changes when the index basket changes and is calculated in accordance as quotient of division INDEXold by INDEXnew:
-``` - INDEXold 26,846 - K = ------------ = ------------ = 0,95951 - INDEXnew 27,979 -``` -where: -- INDEXold – the last index value calculated from the old basket on 30.06.2022;
-- INDEXnew – the first index value calculated for the new basket at the same time as INDEXold;
- -> In order to index can reliably reflect the market picture, a periodic change of the basket of stocks included in the index is required. Therefore, we will publish a new price identifier quarterly. - -### Weekend timestamp -Over the weekend or some official holidays the REST API does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). -Due to unavailability of price feed for stock exchange rates over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. -If a request timestamp takes place on a weekend or any other day the stock market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. -### Stock markets working hours -Underlaying assets trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. -### Price feed -Our price-feed provider’s API documentation can be found [here](https://rapidapi.com/principalapis/api/stock-data-yahoo-finance-alternative/).
-A reference price feed implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/unisxapp/protocol/blob/USPAC5PriceFeed/packages/financial-templates-lib/src/price-feed/DefaultPriceFeedConfigs.ts)
-"Stock Data – Rapidapi.com" is provided as an accessible source to query for this data, but ultimately how one queries for these rates should be varied and determined by the voter to ensure that there is no central point of failure.
-In the case of a "Stock Data – Rapidapi.com" outage voters can turn to any other available price feed API or a broker API, as the price feeds for the forementioned financial assets does not differ much between different providers. There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes. For this case, we provide options for additional price feed providers that voters could utilize. -### Additional price feed providers -- **Yahoo Finance – Rapidapi.com**

The hub collects messages sent between an "oracle spoke" deployed on any non-mainnet EVM networks and the DVM on mainnet, and therefore it must be approved to submit price requests to the DVM. It might be helpful to review [this UMIP](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-113.md) that approved an "oracle root tunnel" that specifically sent messages between Polygon and Ethereum. The oracle hub is similar to the root tunnel except that it can be used for other EVM networks besides Polygon and it can communicate with many networks at the same time, hence why its referred to as an N-to-1 "hub" and not a 1-to-1 "tunnel". - -# Cross Chain Infrastructure -[This folder](https://github.com/UMAprotocol/protocol/tree/34f3180b48397a2ba9211cc6fae33a327b9cb165/packages/core/contracts/cross-chain-oracle) contains contracts that are built on top of bridge protocols to enable UMA's Optimistic Oracle and -Governance contracts to send messages across EVM networks. - -## Hub and Spoke Architecture -*Hub and *Spoke contracts are included that are respectively deployed on "Parent" and "Child" networks. As the Hub -and Spoke names imply, one Hub is designed to service many Spokes. For example, the `OracleHub` can broadcast price -resolutions from the DVM on mainnet to any number of `OracleSpoke` contracts on other EVM networks like Polygon, -Arbitrum, Optimism, and more. Similarly, the `GovernorHub` can be used by the DVM to send governance transactions to -any number of `GovernanceSpoke` contracts on other EVM networks. - -Hub and Spoke contract implementations are network agnostic, but Messenger contracts are network-specific because -they are the contracts that actually send intra-network messages. - -## Parent and Child Messengers -*Hub and *Spoke contracts communicate via a Parent-Child tunnel: a `ParentMessenger` contract is always deployed -to the network that the *Hub contract is deployed to, and the `ChildMessenger` contract is always deployed to the -*Spoke contract's network. - -So, *Hub and *Spoke contracts have a "1-to-N" relationship, and each *Hub and *Spoke pairing has one `ParentMessenger` -and `ChildMessenger` contract deployed to the *Hub and *Spoke networks respectively. - -Depending on the specific EVM networks that the *Hub and *Spoke contracts are deployed to, the implementations of the -Messenger contracts will differ. For example, sending messages between Mainnet and Arbitrum requires calling different -system contract interfaces than sending messages between Mainnet and Polygon does. This is why each network has its own -Messenger contract implementation in the `/chain-adapters` folder. - -# Technical Specification -To accomplish this upgrade, the following actions need to be taken: -- The `OracleHub` will need to be registered with the `Registry` so that it can make requests to the DVM.

The token is a synthetic index based on the recent trading prices of CryptoPunks. The previous price identifier ```PUNKETH-1221``` found in [UMIP 130](./umip-130.md) is not being re-used due to the fact that it was built for the EMP contract. This UMIP re-uses the logic of the previous ```PUNKETH``` price identifier from [UMIP 84](./umip-84.md) and uses the expiry timestamp per contract deployment to allow the creation of multiple overlapping uPUNK contracts. The ```PUNKETH_TWAP``` price identifier is ignored as the LSP is un-liquidatable and this logic is not necessary. - -The DVM should support requests for a price that resolves to the median most recent purchase price (in ETH) of each unique CryptoPunk traded in the last `T` seconds, as specified in the contract's ancillary data. - -# Motivation - -There are currently few synthetic non-fungible token (NFT) indexes available in the DeFi space.

This originality has lead to them being highly valued and having consistent enough trade volume. -* _Median Price_: The median price allows for the index to reflect common trading prices across many CryptoPunks rather than to respond to particular transactions. The default median timeframe is 30 days, and may be changed per LSP contract using ancillary data. -* _Unique CryptoPunks_: We only use the most recent trade price for each CryptoPunk. This is a security feature since if we used each transaction then a single person could trade one CryptoPunk amongst accounts they owned to manipulate the price. -* _Median rather than the mean_: Calculating the mean incorporates the price of every single transaction which means that someone who owned a single CryptoPunk could have a small effect on the price. The median can still be manipulated but, given the uniqueness restriction above, it would require someone to own enough CryptoPunks to make up half of the monthly transactions. - - -# Implementation - -When a price request is made, the following process should be followed: - -1. Determine the timeframe `T` used to calculate the price from Ancillary Data. See the *Ancillary Data Specifications* section for more infomation on retrieving this data. -2. Retrieve all CryptoPunk `PunkBought` events from `T` seconds prior to expiration -3. Identify the last price that each CryptoPunk was traded at using the event data -- Only one price should be produced per CryptoPunk even if they had traded multiple times. Due to a [bug in the CryptoPunk Market](https://github.com/UMAprotocol/UMIPs/pull/261#discussion_r622282931), this isn't as straightforward as reading the most recent value from the `PunkBought` event. The process we use is: - - Scan through all of the `PunkBought` events and identify the function call that generated the `PunkBought` event: - - If it was generated by `buyPunk` then use the `PunkBought.value` price - - If it was generated by `acceptBidForPunk` then we load all of the `PunkBidEntered` for that particular CryptoPunk and use the most recent bid (only one bid can be outstanding at a time and is always the highest) - - In both cases, we ignore any trades that are registered with a price of 0 and look back to the most recent non-zero price. -4. Take the median of these prices - If there is an even number of prices, take the mean of the two values closest to the median. - - - -**Example** - -If `T` from ancillary data is `2592000` and the timestamp requested was `1619222400` then: - -* We would need to identify all `PunkBought` events from `1619222400 - 2592000 -> 1616630400` to `1619222400` -* Imagine that we had 5 `PunkBought` events with (`ts`, `punk_id`, `eth`) pairs of `[(1616630450, 1000, 20), (1616631450, 5000, 30), (1616631550, 5000, 35), (1618631550, 6000, 22), (1618632550, 9999, 15)]`. -* We would need to check what function generated each `PunkBought` event. Suppose they were all generated by `buyPunk`, then the prices we would use to compute the median would be `[20, 35, 22, 15]` -* There are an even number of values, so there's no "median value" in the data -- Thus we find the number between the two values closest to the median `[20, 22]` to get a price of `21` - - - -# Security Considerations - -One of the main concerns is that someone with sufficient CryptoPunks chooses to manipulate the price. - -For example, there are accounts that own about 400 unique CryptoPunks and the unique number of CryptoPunks that traded in the last 30 days is about 600. An individual who owns 400 CryptoPunks and traded them amongst their own accounts at prices near zero could corrupt the price by driving it to zero after having minted and sold the tokens at a high price. - -One benefit to using an oracle with human intervention is that voters could recognize this type of price manipulation and there are other viable proxies for the expected price of a CryptoPunk.

The timeframe of this median value will depend on the value in the ancillary data field of the contract. - -The DVM should support requests for a price that resolves to the median monthly Ethereum gas price as specified in the implementation section, without needing the additional logic of previous UMIPs that contain EMP-specific AMM TWAP liquidation procedures. - - -# MOTIVATION -This UMIP updates the existing motiviations for uGAS as described in [umip-16](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-16.md) and [umip-20](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-20.md). The motivation from [umip-22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md) is no longer needed as there is no liquidation process for LSP contracts. - -From UMIP-16: - -> Cost: Calculating an aggregatory statistic of gas prices on a confirmed block or range of blocks on the Ethereum blockchain is easy by virtue of the fact that all needed data is readily available on any Ethereum full node, whether run locally or accessed remotely through well-known providers such as Infura or Alchemy. Additionally, this data can be accessed through querying publicly accessible Ethereum blockchain data sets. -> -> Opportunity: Gas options/futures can help users and developers hedge against gas volatility allowing them to budget their gas consumption efficiently. Providing a price feed for settlement is a prerequisite. - -From UMIP-20: -> For the creation of a tokenized gas price futures contract, it is desired that the DVM return the aggregatory gas price for 1 million units of gas. Using the gas price for a million units of gas is more suitable for a tokenized futures contract because tokens will actually represent a non-negligible amount of value. If a token was built with the identifiers defined in UMIP-16, participants would need to transact in millions/billions of tokens to capture any substantial value, as the price of each token would be somewhere in the range of 10-150 Gwei. - -# MARKETS & DATA SOURCES - -Information necessary to determine a price for this price identifier requres access to an ethereum full node, either run locally or accessed remotely through well-known providers such as Infura or Alchemy is.

(The above number shows a 30 day median.) In order to work with the previous calculations, this number should be rounded to the nearest previously approved median time period (in whole hours) as seen in the *Rationale* section. This number is to then be used to determine the minimum number of blocks used to calculate the median gas price over that time period as described in that section and the *implementation* section. - -When the above example ancillary data is stored as bytes, the result would be: `0x4e3a373230` - -if there is no ancillary data present, this value should default to `720` which is 30 Days. - -# RATIONALE - -From UMIP-16: - -> The volatility of gas prices on Ethereum is a well-recognized problem that is only made worse by the ever increasing network congestion in recent months. This creates an opportunity for options/futures underwriters to create financial products that help decentralized applications (dApps) and their users hedge against gas price variability and have a consistent risk-minimized experience. The UMA protocol is well-positioned to provide the necessary plumbing for such products to flourish. Such products will need to rely on the DVM as a settlement layer in case of disputes. Therefore, by supporting data feeds for gas prices, the DVM opens the door for a win-win-win situation between financial products, users/dAaps, and the Ethereum network at large. - -In the following quote, the wording is taken from UMIP-16 but the `gas_price` parameter was updated to `effective_gas_price` to account for EIP-1559 as described in [UMIP-129](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-129.md). - -> Each transaction included in an Ethereum block pays an amount of Ether per 1 unit of gas consumed. That amount is (a) specified by a `effective_gas_price` parameter attached to a transaction, (b) is expressed in the smallest unit of the Ether currency which is `Wei`, and is set by the transaction submitter as a bid offered to the miners to have the transaction included. We therefore have a set of `effective_gas_price`s per block. -> -> There are two important factors to consider: (1) there is a block each 12-15 seconds in the Ethereum blockchain, and spikes in gas prices are routinely observed, and (2) miners can easily manipulate gas prices in a given block (especially in absence of a fee burn). Therefore, an aggregatory statistic needs to be computed over a sufficiently long range of blocks to proof against abnormalities whether due to extreme volatility or miner manipulation. We propose the median gas price over 1 hour (1HR), 4 hours (4HR), 1 day (1D), one week (1W), and 1 month (1M) periods _weighted by_ the gas used in a transaction. For safety and to proof against price manipulation and/or possible abnormal delays in block production, the DVM requires that a minimum number of blocks must have been mined within a given period. Otherwise, the DVM medianizes over a preset number of blocks defined in the following table: - -Updated table clarifying median price durations to use for this UMIP. - - | Identifier | Number of Hours Contained (N) | Minimum number of mined blocks (B) | - |-------------|--------------|----------------------------------| - | GASETH-1HR | 1 | 200 | - | GASETH-4HR | 4 | 800 | - | GASETH-1D | 24 | 4800 | - | GASETH-7D | 168 | 33600 | - | GASETH-30D | 720 | 144000 | - -> For example, if the GASETH-1HR is requested for `t1` = October 1st 2020 UTC 00:00:00, and the number of blocks mined between `t0` = September 30th 2020 UTC 23:00:00 and `t1` is less than 200, then the DVM medianizes over the 200 blocks mined at time <= `t1` regardless of how long (in wall clock time) it took for these blocks to be mined. - -# IMPLEMENTATION -DVM voters should use the timestamp from the contract that is being voted on. This timestamp can either be queried from the `expirationTimestamp` field in the LSP contract or from the `timestamp` field in the data of the `requestPrice` price function when `expire` is called.

DVM reporters are free to develop additional implementations, as long as the implementations agree with the computation methodology defined in the *Rationale* section and specifications of the *Technical Specifications* section. - -# Security considerations - -From UMIP-16 - ->Anyone relying on this data point should take note of the fact that manipulating the gas prices in a **specific** block or a short range of blocks is achievable by miners whether to inflate or deflate them for their own self-interest or on behalf of an attacker that bribed them to do so. The longer the range the requested statistic covers, the less the risk of manipulation is. This risk will also be significantly inhibited once [fee burn](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1559.md) is introduced in the Ethereum blockchain, because stuffing/padding blocks will have a non-zero cost even to miners (PoW) or block-producers (PoS). -> ->A large enough number of UMA governers should be running their full node to ensure data integrity. Relying on third-party full nodes presents a risk of manipulation of data, however if at least **one** governer is relying on their own full node, such manipulation is easily detectable.

This upgrade will enforce that DVM balance snapshots are captured from EOA wallets to prevent the use of flash-loans in this context. This upgrade will also change the rewards expiry timeout from 2 weeks to 1000 years, which effectively amounts to no expiration. - -## Motivation & Rationale - -The UMA voting mechanism uses a commit-reveal scheme, where votes are weighted in proportion to the token balance of the voters. The corresponding snapshot of the token distribution is taken at the start of each reveal phase, either through a dedicated function call, or automatically alongside the first revealed vote. - -However, it is possible for users to take out a flash loan of UMA tokens from a decentralized exchange, trigger the snapshot and then repay the loan in a single transaction. This would arguably give them undue influence over the result of the vote. Given the current state of the DeFi ecosystem, the flash-loan scenario is significantly simpler, more plausible, and arguably more concerning, so it warrants a dedicated mitigation. - -This UMIP proposes a solution that makes it imposable to utilize flash loans during voting, thereby enforcing that users hold UMA tokens beyond a single block if they wish to participate in governance. - -This UMIP was originally motivated by an analysis conducted by the UMA engineering team that identified the issue in July 2020. The analysis can be found [here](https://docs.google.com/document/d/11ap5q2ga2OaVIV6MLxpRjzbLZTr0xraUIt2DdfcyzWI/edit?usp=sharing). There was also a detailed discussion in the OpenZepplin Community forum on the implementation details of this solution which can be found [here](https://forum.openzeppelin.com/t/erc20snapshot-and-flash-loans-swaps-mints/3094). - -While redeploying the new version of the contract, the parameters can be reconsidered. The community has expressed dissatisfaction with the 2-week reward expiration. While the voting contract is being modified, it seems prudent to effectively remove this expiration. - -## Technical Specification - -This UMIP addresses the flash-loan scenario by requiring the address that triggers the snapshot to provide an ECDSA signature over a known message, which guarantees that it is an externally owned account(EOA). For simplicity, the ability to automatically trigger a snapshot on the reveal has been removed, although the same effect can be achieved with multiple function calls. - -The implications of this are that the first revealer is required to submit two transactions: - -1. Call `snapshotCurrentRound` with an ECDSA signature which is used to capture the UMA token balances for the voting round. The inclusion of this signature ensures that only EOAs can preform the snapshot as an ECDSA signature can not be generated by a smart contract within a flash-loan. -2. Call `revealVote` to reveal their vote in the normal flash-loan. - -All subsequent voters can call `revealVote` as they would previously have done. - -As for the rewards expiration, voters will be able to wait as long as they like before retrieving their rewards. - -## Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/packages/core/contracts/oracle). The directory contains the [implementation](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/oracle/implementation/Voting.sol) of the `Voting` contract which preforms the key voting logic within the DVM and has the updated logic to include the ECDSA signature verification. - -The specific changes made in this UMIP can be seen in [this](https://github.com/UMAprotocol/protocol/pull/1767) pull request. - -The new Voting contract should have identical parameters to the pre-existing Voting contract, except that rewardsExpirationTimeout will be equal to `31536000000` (1000 years in seconds). - -## Security considerations - -These changes _have_ been audited by OpenZeppelin and the full audit report can be read [here](https://blog.openzeppelin.com/uma-audit-phase-3/). diff --git a/research/uma/umips/UMIPs/umip-150.md b/research/uma/umips/UMIPs/umip-150.md deleted file mode 100644 index 38e11995..00000000 --- a/research/uma/umips/UMIPs/umip-150.md +++ /dev/null @@ -1,39 +0,0 @@ -**UMIP-150** - -- **UMIP title:** Add UMA as collateral currency on Polygon -- **Author:** Geoff (stadnykgeoff1@gmail.com) -- **Status:** Approved -- **Created:** 15 February 2022 -- **Discourse Link:** https://discourse.umaproject.org/t/create-add-uma-as-collateral-currency-to-polygon-md/1408 - -## Summary (2-5 sentences) - -This UMIP proposes adding UMA on Polygon for use as collateral in UMA contracts. - -## Motivation - -The addition of this collateral currency offers additional functionality to the UMA protocol and increases the range of contracts that can be built. - -## Technical Specification - -To accomplish this upgrade, the following changes need to be made: - -- The UMA address https://polygonscan.com/token/0x3066818837c5e6ed6601bd5a91b0762877a6b731 needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 250 UMA needs to be added in the Store contract. -- A final fee for the UMA Mainnet address https://etherscan.io/token/0x04Fa0d235C4abf4BcF4787aF4CF447DE572eF828 needs to be updated from 90 to 250. - - -## Rationale - -This store fee was chosen as it is approximately equivalent to $1500 in line with other collateral currencies as determined by CoinGecko - -## Implementation - - -This change has no implementations other than the aforementioned governor transactions - -## Security considerations - -Adding a collateral currency introduces a level of risk into the UMA Ecosystem.

The approved PIP directory contains all necessary steps, software, and endpoints to validate an index. - -The index can be looked up and validated by participants of the DVM and/or disputers through the `timestamp` and `ancillaryData` passed into the Skinny Optimistic Oracle's `requestAndProposePriceFor` function. The `ancillaryData` consists of the methodology, time period, and target asset concatenated into a single parameter: `id:{METHODOLOGY}-{TIMEPERIOD}-{ASSET}`. This parameter can be deconstructed and used to access data sources. If `ancillaryData` does not comply with these standards, DVM participants should return the "magic number": `-3735928559`. The "magic number" should also be returned for instances where the `ancillaryData` is formatted correctly but where the methdology, time period, and/or targetAsset are not defined/whitelisted within the Volatility DAO's PIP approved repository. We understand that this is a non-traditional format for `ancillaryData` but it is necessary to optimize storage within The DAOracle smart contracts. - -For an example of how to use the `ancillaryData` to recreate an index please see Implementation below. - -Redundancies for accessing data - -Each PIP contains information on how to access raw data. In general there are two ways of doing this: - -1. Most indices will post to IPFS and their data snapshot can be queried through two different URLs: -* One based on methodology, time period, asset, and timestamp. -* One based on the IPFS hash. -2. In cases where the IPFS data is completely lost or broken, the PIP directory of the methodology will outline alternate ways of accessing the data in the README.md (e.g. it may list the exchanges or other third-party data provider from which the data originated and any special processing needed for aggregating the feed(s) for input to the open-source implementation). - -As part of the PIP process The Volatility DAO sets a parameter called `dataPeriod`. This represents the time period at which snapshots of input data & index values are saved to IPFS (or another open immutable database). `dataPeriod` can be set to any time resolution (e.g. 1 second or 1 hour) but should never be greater than the desired amount of time between audits. Only recent snapshots can be relayed to The Volatility Oracle. DVM participants should also deny submissions of "old data." DVM participants can use the following logic to determine if data is considered old: - -``` -submissionBlockTime = the UTC time of the tx to the Skinny OO -timestamp = the UTC timestamp of the snapshot data -disputePeriod = the amount of time where a user can dispute a value within the Volatility Oracle - -Data is old if the following is TRUE: - -submissionBlockTime > timestamp + disputePeriod - -``` - - - -## Rationale -Rationale For the Volatility DAOracle: - -Getting frequent index results on-chain through the Optimistic Oracle is not tenable because of the Tragedy of the Commons. It is not in an individual user’s best interest to pay gas to create a frequent audit trail (e.g. economically it makes sense for an individual user to requestPrice infrequently). The Volatility DAOracle solves this by building a new layer of incentives on top of the Optimistic Oracle. - - -Rationale For This Specific Implementation: - -Having all Volatility DAO indices and benchmarks under one UMIP is important because each individual methodology can be applied across different time periods and assets. For example, with the initial Model Free Implied Volatility methodology (MFIV) an index could be created for ETH or BTC for time periods ranging from roughly 1-364 days. This means that the single methodology could create roughly 728 indices. It would not make sense to create 728 different UMIPs, one for each index. Instead, we feel the best method is to have a single UMIP that defines an overarching framework for cataloging and querying each Volatility DAO index, its implementation, raw data, and methodology. - - -## Implementation -Using the `timestamp` and `ancillaryData` from a `requestAndProposePriceFor` for this UMIP you can query all necessary tools to recreate any index within the Volatility DAOracle. The `timestamp` is seconds since the Unix epoch. The `ancillaryData` consists of three data points concatenated into a single parameter: `id:{METHODOLOGY}-{TIMEPERIOD}-{ASSET}`. - -* `METHODOLOGY` - This is the identifier for the methodology. This four-character identifier can be used to look up the methodology in the [Volatility DAO Github](https://github.com/Volatility-DAO/PIPS/tree/main/Approved/Volatility_Oracle_PIPs). -* `TIMEPERIOD` - This is the time period to which the methodology is applied. Time period uses standardized time formats, where lower-denomination units are lowercase and higher-denominations are uppercase: - * `s` = seconds - * `m` = minutes - * `h` = hours - * `D` = Days - * `W` = Weeks - * `M` = Months - * `Y` = Year - * For example, 14D means 14 Day volatility. -* `ASSET` - This is the asset of which volatility is measured. For example, ETH means Ethereum and BTC means Bitcoin. - * Note: Each methodology that is approved within the Volatility DAO PIP repository has an Index_PIPs directory. That directory contains all of the parameters for the indices of the methodology as MD files. The naming convention of the MD file is the same as the `ancillaryData`. These files whitelist the `targetAsset`to remove the possibility of collision. - -The following example demonstrates how this system works: -1. Use `ancillaryData` and `timeStamp` from `requestAndProposePriceFor`: - * ancillaryData: `id:MFIV-14D-ETH` - * timeStamp: `1643288400` -2. Use the `timestamp` and `ancillaryData` to look up the following: - * MFIV matches the methodology directory [here](https://github.com/Volatility-DAO/PIPS/tree/main/Approved/Volatility_Oracle_PIPs). This is where you get the open-source code to validate the index. The README.md of the methodology directory will have clear instructions on how to validate an index. - * Within the methodology directory is an Index_Pips directory. This must contain an md file named the same as the 'ancillaryData' (i.e. MFIV-14D-ETH.md). - * `timestamp / TIMEPERIOD / ASSET` are all used to query the IPFS data of the calculations. Instructions for doing this are required within the README of every PIP. You can see the MFIV README [here](https://github.com/Volatility-DAO/PIPS/blob/main/Approved/Volatility_Oracle_PIPs/MFIV/README.md). - * NOTE: `timestamp` is the timestamp of the post of data to IPFS. This IPFS data file includes the input and output data for an index. An index can only be queried as often as this data is posted to IPFS. - * NOTE: The Volatility Oracle or other requestor should send the `timestamp` used to query the IPFS file. If this `timestamp` does not allow for a query, then DVM participants should return the "magic number" (described above). - - -## Security considerations -There are several potential security considerations. Each of these has been mitigated as much as possible: - -* **Data** - To create an index on the DAOracle a creator needs to provide the input data on IPFS. The infrastructure that they use to do this could be a vector of attack or could simply break. As a redundancy, the creator must also describe how to access and filter raw data. In many cases the raw data could also be a vector of an attack. The methodology should try to address this if possible. However, it may not be possible to mitigate attacks on raw data (e.g. a price series from an exchange). - -* **Volatility DAO** - * GitHub - The Volatility DAO GitHub could be a vector of attack. For example, if someone were to gain access who should not have access. Every DAO member who has access to the repo uses basic security features like 2FA and signed commits. - * 51% attack - 51% of VOL tokens could be acquired by someone to change how an index calculates. This is mitigated by the process in which indices are approved. All indices must use open-source software and must go through a period of public review. Inserting malicious code would be possible if someone owned 51% of tokens, but users would know that the code is malicious and could avoid using it. Furthermore, the UMA community could be notified at that point and time and could take action to invalidate this UMIP. - diff --git a/research/uma/umips/UMIPs/umip-152.md b/research/uma/umips/UMIPs/umip-152.md deleted file mode 100644 index 0d16bf21..00000000 --- a/research/uma/umips/UMIPs/umip-152.md +++ /dev/null @@ -1,284 +0,0 @@ -## Headers -- UMIP-152 -- UMIP title: Add ZODIAC as a supported price identifier -- Author: John Shutt (john@umaproject.org) -- Status: Approved -- Created: March 7, 2022 - -## Summary (2-5 sentences) -The ZODIAC identifier is intended to be used with an [Optimistic Governor](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/zodiac/OptimisticGovernor.sol) [Zodiac module](https://gnosis.github.io/zodiac/docs/intro) that allows you to control a [Gnosis Safe](https://gnosis-safe.io/) according to a set of rules defined off-chain and enforced with UMA's [Optimistic Oracle](https://umaproject.org/optimistic-oracle.html). Any address can propose transactions that follow the rules and any address can dispute a proposal to UMA's Optimistic Oracle within a challenge window. - -## Motivation -The ZODIAC identifier, coupled with the Optimistic Governor module, will allow for a new era of flexible "optimistic governance," where management of DAO treasuries and other multi-signature wallets can be managed more effectively, without being limited to X-of-Y signing schemes or tokenholder votes, although the Optimistic Governor module can enforce those things, too. - -To date, DAO governance has twisted itself to conform to the limitations of simplistic tools, instead of finding the best rules to coordinate around shared resources. The ZODIAC identifier allows a DAO to publish their rules in plain language with sufficient detail for a neutral third-party observer to determine whether transactions submitted to a Gnosis Safe follow the rules or not, and then have any address propose and execute transactions that follow those rules. - -Because human voters can be brought in the loop to resolve disputes, this is an incredibly flexible and powerful form of DAO governance. Due to that flexibility, users of this identifier should be sure to make their rules as clear as possible, including the process for upgrading to a new set of rules. - -## Technical Specification -The Optimistic Governor module is a new tool and can be paired with an administrative multi-signature scheme for emergency actions for greater user assurance. Over time, the signature threshold can be increased for the emergency multi-sig, and eventually the multi-sig can be eliminated entirely, with all governance actions going through the Optimistic Governor. - -Each Gnosis Safe will have its own Optimistic Governor module contract which will store a hash of transactions proposed by external addresses. Each proposal hash represents a bundle of transactions and each proposal emits an event with the full transaction details. - -``` - -event TransactionsProposed( - address indexed proposer, - uint256 indexed proposalTime, - Proposal proposal, - bytes explanation, - uint256 challengeWindowEnds -); - -struct Transaction { - address to; - Enum.Operation operation; - uint256 value; - bytes data; -} - -struct Proposal { - Transaction[] transactions; - uint256 requestTime; -} -``` - -The module contract stores a mapping of proposal hashes to their proposal time, to verify proposals during execution and to prevent duplicate proposals. The contract also stores a string reference to an off-chain set of rules that have been publicly published, which may be an IPFS hash, a URI, or something else. - -Other important configuration variables stored by the contract are the collateral token address (for bonds), the amount of collateral tokens proposers and disputers are required to post as a bond, the liveness period for disputes, the identifier used by the module, and the address of the Optimistic Oracle and the Finder. - -``` -// This maps proposal hashes to the proposal timestamps. -mapping(bytes32 => uint256) public proposalHashes; - -// Since finder is set during setUp, you will need to deploy a new Optimistic Governor module if this address need to be changed in the future. -FinderInterface public immutable finder; - -IERC20 public collateral; -uint64 public liveness; -// Extra bond in addition to the final fee for the collateral type. -uint256 public bondAmount; -string public rules; -// This will usually be "ZODIAC" but a deployer may want to create a more specific identifier. -bytes32 public identifier; -OptimisticOracleInterface public optimisticOracle; -``` - -When a user creates a proposal, they submit an array of transactions along with an optional explanation that explains the intent and purpose of the transactions, which is useful for voters trying to understand the transactions and whether or not they follow the published rules. - -``` -function proposeTransactions(Transaction[] memory transactions, bytes memory explanation) public { - ... -} -``` - -In this function, a price request and price proposal are submitted to the Optimistic Oracle, and the proposal hash is generated and stored in a mapping to the proposal time. - -``` -// Create the proposal hash. -bytes32 proposalHash = keccak256(abi.encode(_transactions)); - -// Add the proposal hash to ancillary data. -bytes memory ancillaryData = AncillaryData.appendKeyValueBytes32("", "proposalHash", proposalHash); - -// Check that the proposal is not already mapped to a proposal time, i.e., is not a duplicate. -require(proposalHashes[proposalHash] == 0, "Duplicate proposals are not allowed"); - -// Map the proposal hash to the current time. -proposalHashes[proposalHash] = time; - -// Propose a set of transactions to the OO.

Without a flexible, natural language based system for outlining rules of operation, and a trustless and decentralized mechanism for enforcing those rules, DAOs can only exist in a stunted form, like an oak tree growing in a pot with no space for deep roots. - -This UMIP and the associated module code brings the flexibility of law to smart contracts, with UMA voters serving as judge and jury in case of disputes. Unlike the tradition of common law, however, UMA voters do not attempt to create precedent for ambiguous cases, resolve controversy, or fill in the gaps. If there is ambiguity about whether a particular proposal follows the rules, it is simply rejected. - -The onus is on the DAO to write clear rules and on the proposer to ensure their transactions follow the rules, with no room for ambiguity by a neutral third-party observer. - -This methodology allows for a huge amount of flexibility for DAOs to manage their shared resources without requiring UMA voters to make subjective judgements, which would be difficult for voters and could potentially create unpredictable and undesirable results for DAOs. - -## Implementation -Voters should read the plain language rules referenced in the public `rules` value in the Optimistic Governor contract that requested a price and check the proposed transactions against those rules. - -This `rules` value will usually be an IPFS hash. If it is, voters can view the rules through a web browser by going to https://ipfs.io/ipfs/ or by using any other system to access the document using IPFS. If the `rules` value is a web URI, voters can simply enter the web URI into any web browser. - -The system is quite flexible, so voters may need to find other publicly verifiable data to determine if the proposed transactions follow the rules. For instance, they may need to check the result of a Snapshot vote to verify that a governance proposal was approved by the DAO token holders, or check the current price of a token to verify a proposal to make a trade according to a trading strategy outlined in the rules, or confirm public misbehavior by some address to verify a proposal to slash a bond posted by that address. - -If the proposer included an optional `explanation` in the ancillary data of the price request, that may be helpful for understanding the intent of the proposal, but voters should primarily consider the actual effects of the proposed transactions and verify that the transactions clearly and unambiguously follow the rules. - -If a proposal is disputed, the disputer is encouraged to publish their reasoning in a public forum to assist UMA voters in their determination of whether or not the proposal was valid. - -Voters should consider four sources of public information in their ruling: - -1. The published rules for the Optimistic Governor module. -2. The rationale given by the proposer in explanation (if any). -3. The arguments presented by disputers. -4. The voter's understanding of what the transactions *actually* do, regardless of the stated rationale. - -If a proposal follows the rules, an UMA voter should return a value of `1`. - -If a proposal doesn't follow the rules, an UMA voter should return a value of `0`. - -If a voter is unsure if a proposal follows the rules, an UMA voter should return a value of `0`. - -If the rules are unclear or malformed, an UMA voter should return a value of `0`. - -It is the responsibility of the DAO users of the `ZODIAC` identifier to write clear and unambiguous rules. If their rules are unclear, they should expect proposals that get disputed to be rejected by UMA's oracle. - -It is important that the process for changing the rules be particularly clear and unambiguous, if a rule change process is allowed by the DAO. This allows the DAO to add, remove, or clarify rules as needed, analogous to a constitutional amendment. - -The implementation of the Optimistic Governor module can be [found here](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/zodiac/OptimisticGovernor.sol). - -The requester will be the Optimistic Governor contract itself, which means voters can use the requester address to find the contract on Etherscan and inspect the public `rules` value. - -### Example Rules -The `ZODIAC` identifier is designed to allow rules to be as flexible as possible while still being clear to UMA voters called in to resolve disputes. These examples are meant to inspire creativity in users creating their own rules and demonstrate the legalistic approach they should take. - -The actual rules for a given module will depend entirely on the intended use of the Gnosis Safe governed by that module and the community dynamics of the DAO in charge. - -As a reminder, these rules should be published publicly and referenced in a string stored in the module contract, as an IPFS hash, a website URI, or some other format. - -``` -EXAMPLE RULES - -ABC DAO was formed to bring our token holders to the moon, Mars, and beyond. - -To that end, we have established the following rules governing our treasury, contained in the Gnosis Safe at Ethereum address 0xbcd...234. This Gnosis Safe also has the ability to change certain parameters in our other smart contracts. - -1. Transactions proposed by 0xabc...123 are valid unless they violate other rules. This address is a multi-signature wallet controlled by the core development team. - -2. No more than 10% of the value contained in the Gnosis Safe at address 0xbcd...234, which is governed by the Zodiac module 0xcde...345, may be transferred out of the Gnosis Safe during a single 24-hour period. - -3. Proposals including transactions that call functions on the smart contract 0xdef...456 must be approved by a Snapshot vote backed by more than 50% of the total supply of $ABC ERC-20 tokens and must be proposed by 0xabc...123. - -4. Proposals that have been approved by a Snapshot vote backed by more than 50% of the total supply of $ABC ERC-20 tokens are valid. - -5. Transactions proposed by an address owned by Elon Musk are valid unless they violate other rules. Elon Musk can prove ownership of an address through a post on the @elonmusk Twitter account combined with a public press release. - -6. These rules may be changed at any time by a transaction approved by a Snapshot vote backed by more than 50% of the token supply of $ABC ERC-20 tokens, or by Elon Musk. - -7. Elon Musk may not propose transactions when it is the second Tuesday of the month, Pacific Time Zone. -``` - -### Successful Execution Flow -1. DAO member Alice has a great idea for utilizing the DAO treasury and writes some Ethereum transactions that would execute her idea. -2. Alice holds a Snapshot vote to approve their idea and associated transactions. -3. The majority of $ABC tokens back Alice's proposal in the Snapshot vote. -4. Alice submits the proposal to the Zodiac module governing the Gnosis Safe and notes in the explanation that the proposal was approved on Snapshot and includes a link to the Snapshot results. Alice includes a bond with her proposal. -5. The proposal is not disputed within the challenge window and can be executed by any address. -6. Bob, another member of the DAO, executes Alice's proposal since Alice is out watching a movie. -7. Alice's transactions are executed and the treasury funds are spent according to her plan, which was approved by a Snapshot vote. - -### Disputed Execution Flow -Starting after step 4 from the Successful Execution Flow: - -1. Bob, who is jealous of Alice's popularity in the DAO, disputes her proposal even though it has been approved by a Snapshot vote. Bob includes a bond with his dispute and rages against the proposal on Twitter. -2. The dispute is escalated to UMA's data verification mechanism where UMA tokenholders analyze the proposal, the arguments from Alice and Bob, and the rules published by the DAO and referenced in the Zodiac module. -3. After reading the rules, the vast majority of UMA token holders conclude that the proposal followed the rules and should be executed, and commit a value of `1` during the commit period. -4. UMA token holders reveal their votes during the reveal period. -5. After the reveal period, the settlement value is `1`. The Zodiac module receives the settlement value and allows any user to execute the proposal. -6. Bob loses his bond and Alice gets her bond back and a portion of Bob's bond. -7. Alice, vindicated, executes her proposal. - -### Blocked Execution Flow -1. Elon Musk proposes to spend some DAO treasury funds, and includes a bond with his proposal, but it is the second Tuesday of the month, Pacific Time Zone. -2. Alice disputes Elon's proposal and includes a bond with her dispute. -3. The dispute is escalated to UMA's data verification mechanism where UMA tokenholders analyze the proposal and the rules published by the DAO and referenced in the Zodiac module. -4. After reading the rules, the vast majority of UMA token holders conclude that the proposal did NOT follow the rules and should not be executed, and commit a value of `0` during the commit period. -5. UMA token holders reveal their votes during the reveal period. -6. After the reveal period, the settlement value is `0`. The Zodiac module receives the settlement value and deletes the invalid proposal. -7. Elon loses his bond and Alice receives her bond back and a portion of Elon's bond. - -### Emergency Administrative Action -1. The DAO includes an emergency multi-sig that can override any proposal. -2. DAO member Alice has a great idea to steal all of the money in the treasury for herself and writes some Ethereum transactions that would execute her idea. -3. Alice holds a Snapshot vote during a holiday when people aren't paying attention and bribes enough voters to get majority approval. -4. Alice submits the proposal to the Zodiac module governing the Gnosis Safe and notes in the explanation that the proposal was approved on Snapshot and includes a link to the Snapshot results. Alice includes a bond with her proposal. -5. The signers on the emergency multi-sig are alerted in time and delete Alice's proposal. -6. The DAO votes on new rules that would prevent incidents like this in the future. - -## Security considerations - -### Ambiguity -Ambiguous or incomplete rules could put contracts using the `ZODIAC` identifier at risk of loss of funds. The rule that UMA voters should reject proposals that they are not certain follow the rules should help mitigate this. - -### Complexity -Complex bundles of transactions may be difficult for a layperson voter to analyze, leading to reliance on statements made by experts in support of or against a proposal. The rule that UMA voters should reject proposals they are not certain about means that complex proposals that actually do follow the rules may be blocked for some time. - -The DAO can resolve this issue by having alternative and less ambiguous mechanisms for expressing approval of complex proposals. For instance, the DAO's rules may state that a proposal whose transactions received XX% approval through a Snapshot vote, or were signed off on by 3 of 4 experts, should be approved. - -This allows the DAO to establish straightforward rules for simple, routine, or non-controversial transactions that can be proposed by any address and understood by any neutral third party, like an UMA voter. This is much more efficient than putting those transactions through, for instance, a governance vote every time. - -Complex proposals can be put through a more intensive process, like a Snapshot vote, that has an output that will be easy for a neutral third party to understand. - -### Short Challenge Windows -If the rules set by a DAO are complex, or the funds in a Gnosis Safe are substantial, a short challenge window may be a security risk. They may wish to have full flexibility of an off-chain set of rules enforced by the Optimistic Oracle but also set guardrails on what transactions can be triggered according to certain criteria. - -As an example, the DAO's rules may set limits on how much can be transferred out of a Gnosis Safe within a given window. Proposals that would result in greater than 5% of a Gnosis Safe's assets being transferred externally may require a 50% vote on Snapshot by tokenholders. - -The rules may also add additional requirements for special transactions, like changing parameters in a smart contract system controlled by the Gnosis Safe. Those transactions may need to be proposed by a core team member and/or signed off by X-of-Y members of an expert committee. This allows experts and selected DAO members to check important transactions without fully trusting them (after all, they can be off-boarded by tokenholders through a change in the rules). - -The reason to add these extra requirements for complex or potentially risky transactions is to make it easy for oracle observers to evaluate proposals within a short challenge window and dispute proposals that are obviously invalid. - -The more important a transaction is, the more requirements the DAO may want to put into their rules around that transaction. That makes it more likely that a disputer will step in to block bad proposals with confidence that they will be backed up by UMA voters since some unambiguous requirement was not fulfilled. - -### Continued Use of an Emergency Administrative Multi-Sig -In the long run, it should be possible to replace multi-sig control of a Gnosis Safe, with all governance actions going through the Optimistic Governor. While the Optimistic Governor is being implemented, however, and best practices around DAO rules are being established, it may be useful to retain a multi-sig as an emergency override mechanism. - -This multi-sig can protect against failures caused by unclear or inadequate rules or by some issue with the Optimistic Governor itself. However, it is important to remember that the continued existence of an emergency multi-sig adds additional trust assumptions, and it is possible for rogue multi-sig signers to override actions that were approved through the DAO's stated governance system or the will of the DAO expressed through a SafeSnap vote. - -Over time, the signing threshold for the emergency multi-sig can be increased to make it harder for the multi-sig to overrule the normal function of the Optimistic Governor, and eventually the multi-sig administrative powers can be dropped entirely. - -### Poorly Formed Proposals -It is possible that transactions in a proposal may not match the intent of the proposer and may not be well understood by potential disputers. As a result, bad transactions may go through and result in loss of funds or accidents in smart contracts controlled by a Gnosis Safe. - -This can be prevented by adding extra checks for complex proposals. Some examples are given in the "Short Challenge Windows" section above. - -It may be worthwhile to add extra checks even for theoretically simple proposals, since mistakes can happen in simple proposals, too.

Polygon changed the `FxBaseRootTunnel` implementation in September 2021 to be able to accept proofs generated on type 2 (i.e. EIP1559/London) transactions submitted on the Polygon network. - -The `OracleChildTunnel` contract implementation will not be changed and it just needs to be redeployed on Polygon and the Finder needs to point to this newly deployed contract as the "Oracle". - -The reason why this contract bug took so long to be unearthed was that there was no type 2 price request sent from Polygon to Mainnet until [March 27th](https://polygonscan.com/tx/0xc1890ef479579b0da6daeb67ec2522f0e865d2f977096980a98ca38c13526c94).

Once the Polygon block containing the transaction that emitted this event is included on Ethereum, it can be relayed to its target on Ethereum. In order to relay it, a proof must be constructed off-chain that alleges that the `MessageSent` event was included in a block that was checkpointed to Ethereum. The logic that validates this proof is contained in the `OracleRootTunnel` contract, and specifically in the base `FxBaseRootTunnel` contract. This proof-validation logic needs to be upgraded to handle proofs constructed on type 2 transactions. - -## Technical Specification -To accomplish this upgrade, the following actions need to be taken: -- The newly deployed `OracleRootTunnel` on Ethereum will need to be registered with the `Registry` so that it can make requests to the DVM. -- The newly deployed `OracleChildTunnel` will need to be set as the "Oracle" in hex (i.e. `0x4f7261636c65`) in the Polygon `Finder`.

A deposit is a cross-chain transfer request from an "origin" chain to a different "destination" chain, which is fulfilled when a "relayer" sends the depositor their desired transfer amount (less fees) on their desired destination chain. - -Relayers lend capital to the Across V2 system by fulfilling users' deposits via the spokes and are eventually repaid by the LP pool. "Bundles" containing many of these repayments are validated together by the [Optimistic Oracle ("OO")](https://docs.umaproject.org/protocol-overview/how-does-umas-oracle-work). In addition to validating individual repayment instructions, the OO also validates rebalance instructions that tell the LP pool how to transfer funds to and from the spoke pools in order to execute the repayments and pull deposited funds from the spoke to the LP pool. - - -If there is no relayer who can provide all the capital for a given deposit request, a "slow relay" (or "slow fill") is performed where the funds are sent from the -LP pool to the destination spoke to fulfill the deposit. These slow fill requests are also included in the aforementioned bundles. - -Bundles are implemented on-chain as [Merkle Roots](https://www.youtube.com/watch?v=JXn4GqyS7Gg) which uniquely identify the set of all repayments and rebalance instructions over a specific block range.

See the section on [comparing events](#comparing-events-chronologically) for more details. - -Note 3: wherever unspecified, sorting should be ascending by default, not descending. - -Note 4: all event data should be identically returned by at least two independent, reputable RPC providers to give confidence in the integrity of the data. - -# Definitions - -## Comparing events chronologically -Smart contract transactions can emit events that conform to the specifications described in the "Returns" section of these [docs](https://web3js.readthedocs.io/en/v1.2.11/web3-eth-contract.html#contract-events). Specifically, an event is expected to have a unique combination of `blockNumber`, `transactionIndex` and `logIndex`. To compare events `e1` and `e2` chronologically, we can say -that `e1` is "earlier" than `e2` if `e1.blockNumber < e2.blockNumber` OR if `e1.blockNumber == e2.blockNumber && e1.transactionIndex < e2.transactionIndex` OR if `e1.blockNumber == e2.blockNumber && e1.transactionIndex == e2.transactionIndex && e1.logIndex < e2.logIndex`. - -So, "earlier" events have a lower block number, transaction index, or log index, and we should compare event properties in that order. - -## Valid bundle proposals -A root bundle can be proposed by calling `HubPool.proposeRootBundle()`, which will will emit a [`ProposedRootBundle`](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol#L148-L156) event. - -The root bundle is valid once *all* of its `PoolRebalanceLeaves` are executed via `HubPool.executeRootBundle()`, which can only be called after the proposed root bundle's `challengePeriodEndTimestamp` is passed. - -## Comparing deposit events chronologically for different origin chains -Each deposit emits a [`quoteTimestamp`](https://github.com/across-protocol/contracts-v2/blob/aac42df9192145b5f4dc17162ef229c66f401ebe/contracts/SpokePool.sol#L73) parameter. This timestamp should be evaluated within the context of the Ethereum network, and should be mapped to the Ethereum block who's [`timestamp`](https://ethereum.org/en/developers/docs/data-and-analytics/block-explorers/#blocks) is closest to the `deposit.quoteTimestamp` but not greater (i.e. `block.timestamp` closest to and `<= deposit.quoteTimestamp`). - -## Matching L1 tokens to Running Balances or Net Send Amounts -The [`RootBundleExecuted`](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol#L157-L166) event and [`PoolRebalanceLeaf`] structure both contain equal length arrays: `l1Tokens`, `netSendAmounts`, `bundleLpFees`, and `runningBalances`. Each `l1Token` value in `l1Tokens` is an address correspondingto an ERC20 token deployed on Ethereum Mainnet. It should be mapped to the value in any of the other three arrays (`netSendAmounts`, `bundleLpFees`, and `runningBalances`) that shares the same index within the array. - -For example, if `l1Tokens` is "[0x123,0x456,0x789]" and `netSendAmounts` is "[1,2,3]", then the "net send amount" for token with address "0x456" is equal to "2". - -## Versions -The `ConfigStore` stores a "VERSION" value in the `globalConfig`. This is used to protect relayers and dataworkers from using outdated code when interacting with Across. The "VERSION" should be mapped to an integer string that can only increase over time. The "VERSION" is updated by calling `updateGlobalConfig` so it is emitted as an on-chain event. The block time of the event that included the "VERSION" indicates when that "VERSION" became active. Relayers should support the version at the quote timestamp for a deposit, otherwise they risk sending an invalid fill. Proposers and Disputers should support the latest version for a bundle block range to validate or propose a new bundle. This version is independent from the version included in [speed up deposit signatures](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/SpokePool.sol#L668). - -# Ancillary Data Specifications - -The ancillary data only needs a single field: `ooRequester`, which should be the contract requesting the price from the -OO. Because that contract should contain enough information about the request for voters to resolve the validity of the -relay, no additional ancillary data is needed. - -Example: - -``` -ooRequester:0x69CA24D3084a2eea77E061E2D7aF9b76D107b4f6 -``` - -# Configuration Constants - -## Global Constants -The following constants should reflect what is stored in the [`AcrossConfigStore`](https://etherscan.io/address/0x3b03509645713718b78951126e0a6de6f10043f5#code) contract deployed on Etherscan. This contract is owned by Across governance and acts as the source of truth for the following variables. The global variables currently stored in the above contract for this UMIP are: -- "MAX_POOL_REBALANCE_LEAF_SIZE" -- "MAX_RELAYER_REPAYMENT_LEAF_SIZE" -- "VERSION" - - Across protocol version number. Supporting implementations should query this value against the value defined in their implementation to determine compatibility with the current protocol version. Failure to correctly evaluate the version number may mean that filled relays are not refunded from the HubPool, and may therefore result in loss of funds. For more information go [here](#versions). -- "DISABLED_CHAINS" - - This must be a stringified list of chain ID numbers. This cannot contain the chain ID "1", or the HubPool chain ID. Chains in here must be contained in `CHAIN_ID_INDICES`. -- "CHAIN_ID_INDICES" - - This should default to the value [1,10,137,288,42161] for any blocks older than the first time that this global variable was published. This is to account for the initial version of this UMIP which defined this ID list in the UMIP rather than in the ConfigStore contract. Chains can only be added to this list to be valid. - -To query the value for any of the above constants, the `AcrossConfigStore` contract's `globalConfig(bytes32)` function should be called with the hex value of the variable name. For example, the "MAX_POOL_REBALANCE_LEAF_SIZE" can be queried by calling `globalConfig(toHex("MAX_POOL_REBALANCE_LEAF_SIZE"))` which is equivalent to `globalConfig("0x4d41585f504f4f4c5f524542414c414e43455f4c4541465f53495a45")`. For example, this might return ->"25" - -## Token Constants -The following constants are also stored in the `AcrossConfigStore` contract but are specific to an Ethereum token address. Therefore, they are fetched by querying the config store's `tokenConfig(address)` function. -- "rateModel" - - This is a JSON struct of rate model parameters. - - These parameters should fully specify the rate model for this token as described in - [UMIP 136](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-136.md). - - Each field in this struct should be an integer represented as a string (to allow unlimited precision). - - The rateModel struct is only valid if it contains all of the following parameters: `UBar`, `R0`, `R1`, and `R2`. -- "routeRateModel" - - Similar to `rateModel`, this is a dictionary of `originChain-destinationChain` keys mapped to rate models that take precedence over the `rateModel` for a token on that specific deposit route. The route rate models should follow the same `UBar`, `R0`, `R1`, `R2` format as the default `rateModel` -- "spokeTargetBalances" - - This is contains a JSON mapping from chainId to JSON structs. - - Each struct contains two sub-fields, "target" and "threshold". - - Each is an integer represented as a string (to allow unlimited precision). - - These integers should both be positive values. If either is negative, it should be treated as "0" when used. - - The "target" integer should be < the "threshold" integer.

If they don't match or if no matching event is found, the relay is invalid. - -## Validating realizedLpFeePct -To determine the validity of the `realizedLPFeePct` in the `FilledRelay` event, the exact same process is used as in -the identifier [`IS_RELAY_VALID`, specified in UMIP 136](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-136.md). However, instead ofing a `RateModelStore` contract to look up a deposit's rate model, we can use the `AcrossConfigStore`'s `tokenConfig` to [look up the rate model](#token-constants) for a deposit. The deposited `originToken` can be mapped to an `l1Token` by following step 2 above which can be used to query a `rateModel`. - -Moreover, instead of calling `liquidityUtilizationCurrent` and -`liquidityUtilizationPostRelay` on the `BridgePool` contract (passing no arguments) to compute the rate model, identically-named methods would be -called on the `HubPool` contract, passing in a single argument, the `l1Token` derived in the 3 step process above. - -If the `realizedLPFeePct` that is computed using those means does not match the `realizedLPFeePct` in the -`FilledRelay` event, then the relay is considered invalid. - -All valid `FilledRelay` events should then be stored for the construction of the bundle. - -# Finding Slow Relays - -To determine all slow relays, follow the following process: - -1. For all valid `FilledRelay` events above, group them by `originChainId` and `depositId`. -2. Remove all groups that contain a `FilledRelay` event where `totalFilledAmount` equals `amount`. This removes deposits that have been 100% filled. -3. Remove all groups that do not contain an event where `filledAmount` is nonzero and equal to `totalFilledAmount`. This keeps only deposits whose earliest fill is in this time range. - -For all remaining groups, they should be stored in a list of slow relay groups. - -## Computing Slow Relay payment amounts - -For a given slow relay identified [above](#finding-slow-relays), we can compute the associated deposit's "unfilled amount" as `deposit.amount - latestFill.totalFilledAmount`, where `latestFill` is the last fill chronologically for a deposit. Since each fill increments `totalFilledAmount`, the `latestFill` can also be identified by sorting all fills associated wiht a deposit and keeping the fill with the largest `totalFilledAmount`. - -Note: Since we eliminated all fills where `totalFilledAmount == deposit.amount`, the remaining "last fill" should have `totalFilledAmount < deposit.amount` AND have `totalFilledAmount > [all other fills for deposit].totaFilledAmount`. - -# Constructing the PoolRebalanceRoot - -To construct the `poolRebalanceRoot`, you need to form a list of rebalances. - -For all valid `FilledRelay` events above, group them by `repaymentChainId` and their associated `l1Token` found above. - -For each group, sum the `fillAmount` values to get the total relay repayments for that group. - -Similarly, sum the `fillAmount * realizedLPFeePct / 1e18` to get the total LP fees for that group. - -To determine the amount to modify the running balances: - -1. _Add relayer refunds_: For each `FilledRelay` [group](#finding-valid-relays), initialize a running balance value at 0 and add the total relay repayments to - it. Each running balance value is defined by its `repaymentChainId` and `l1Token`. -2. _Add slow fills_: For each [slow relay group](#finding-slow-relays), add each slow relay's [unfilled deposit amount](#computing-slow-relay-payment-amounts) to the group's running balance. -3. _Subtract deposits_: Find all `FundsDeposited` events on all `SpokePool`s from earlier within each `SpokePool`'s block range. Using the - `originChainId`, `originToken`, the `quoteTimestamp`, and the `SetPoolRebalanceRoute` event on the HubPool, use a - similar process as the 3 step one above to map this back to an `l1Token`. For that `l1Token` and `originChainId`, - initialize a running balance value if one doesn't exist already and subtract the `amount` from it. -4. _Subtract excesses from partially executed slow fills_: In the case that a previous slow fill payment was sent to a `SpokePool`, but before the slow fill leaf could be executed, a relayer partially "fast" filled the deposit. Afterwards, the slow fill leaf was executed to complete the remainder of the deposit. The `SpokePool` now has a surplus amount of tokens because the original slow fill payment was not fully used to complete the deposit, so this excess must be returned to Mainnet. This step therefore explains how to identify excesses and determine how much to send back (i.e. subtract from running balances). Find all `FilledRelay` events in the block range that have `isSlowRelay` set to true. For each, use a similar method - as above to [map this event back to an `l1Token` at the `quoteTimestamp`](#matching-l2-tokens-and-l1-tokens). Use the `destinationChainId` as the `repaymentChainId` - to determine which running balance that this event should apply to. For each previously [validated bundle](#valid-bundle-proposals), follow the steps in the ["Finding Slow Relays"](#finding-slow-relays) section - for this `originChainId` and `depositId`, and look for slow relays with a matching - `originChainId` and `depositId`. There should be exactly one slow relay payment matching the `FilledRelay` in question. This is the slow fill that was included in a previous bundle that added to the `runningBalance` and ultimately led the bundle to send a slow fill payment to the `SpokePool` on the `destinationChainId`. Compute the [slow fill amount](#computing-slow-relay-payment-amounts) sent in the older root bundle. The excess amount remaining in the `SpokePool` after this current `FilledRelay` (with `isSlowRelay = true`) is equal to `slow fill amount` minus `FilledRelay.fillAmount`. In other words, if the `FilledRelay.fillAmount` is less than the `slow fill amount` originally sent over in a prior bundle, then send back the difference. Subtract the result from the running - balance for the associated `l1Token` and `destinationChainId`. -5. _Subtract excesses from unexecuted slow fills_: This section is similar to the one above but deals with cases where the slow fill leaf can never be executed. Find all `FilledRelay` events in the block range that have `totalFilledAmount` equal to `amount` (i.e. fills that completed a deposit) and that have `fillAmount` less than `amount` (i.e. fills that were not the first fill for a deposit). If the first fill for a deposit completed a deposit (`fillAmount == amount` and `totalFilledAmount == amount`), then there can be no excess left in the spoke pool because this would not have triggered a slow fill payment to be sent to the spoke. First we need to see if the first fill for this current fill triggered a slow fill. In previously [validated bundles](#valid-bundle-proposals), identify all matching fills for the same `originChainId` and `depositId`. Find the earliest such fill. Determine the block range of the root bundle proposal that contained this fill using [this logic](#determining-block-range-for-root-bundle-proposal) for the `ProposeRootBundle` event with a `bundleEndBlock` for the `FilledRelay.destinationChainId` greater than or equal to the `FilledRelay` block number. Find the last fill in this same bundle block range. The slow fill payment for the bundle should have been `FilledRelay.amount - FilledRelay.totalFilledAmount`, same as [this calculation](#computing-slow-relay-payment-amounts). Since we know that the current `FilledRelay` in this upcoming proposal 100% filled the deposit, we know that the slow fill leaf cannot be executed, so the entire slow fill payment must be sent back to mainnet. Subtract this (the preceiding slow fill payment from a valid root bundle that this fill ultimately completed) from the running balance. - -We now need to add the preceding running balance value to the current one for a given `repaymentChainId` and `l1Token`. -For each `repaymentChainId` and `l1Token` combination, older -[RootBundleExecuted](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol#L157-L166) events -should be queried to find the preceding `RootBundleExecuted` event.

Human intervention in extreme circumstances where the result differs from broad market consensus. -- Price Steps: 0.00001 (5 decimals in more general trading format) -- Rounding: Closest, 0.5 up (>= .000005 rounds up, < .000005 rounds down) -- Scaling Decimals: 18 (1e18) -- Pricing Interval: 60 seconds -- Dispute timestamp rounding: down - -## Rationale - -Apart from the weekend, there is little to no difference in prices on liquid major Forex pairs, so any price feed could be used; however, for convenience, we recommend using the one of TraderMade. - -## Implementation - -Historical NZDUSD prices from TraderMade are available on minute increments. Price requests should use the minute price that is nearest and later than the price request timestamp. To do this, voters should use the open price of the OHLC period that the price request timestamp falls in. TraderMade endpoints are queried based on the OHLC period's close time. - -As an example, a request for a NZDUSD price at 2020-11-11-01:52:16 should use query for the period ending at 2020-11-11-01:53:00 and use the open price. - -The TraderMade endpoint used would be: https://marketdata.tradermade.com/api/v1/minute_historical?currency=NZDUSD&date_time=2020-11-11-13:01&api_key=apikey - -NZDUSD should then be rounded to 5 decimals. - -TraderMade’s price feed is an aggregated feed from multiple Tier One and Two Banks, Market-Makers and Data Providers. They are popular with Quantitative Traders, Fintech companies and Institutional customers who require a high quality and trusted feed. - -### Weekend timestamp - -Over the weekend or some official holidays the REST API does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). - -Due to unavailability of price feed for foreign exchange rates and commodities over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as a official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation). A reference TraderMade implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/TraderMadePriceFeed.ts). - -Our team has adjusted the original Liquidation and Dispute bots in order to fit the interfaces of our protocol. You can find our versions of the Liquidator and Dispute bots on the following GitLab links: - -- [Liquidator Bot](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jrv_bot/packages/liquidator/test) -- [Dispute Bot](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jrv_bot/packages/disputer/test) - -TraderMade is provided as an accessible source to query for this data, but ultimately how one queries for these rates should be varied and determined by the voter to ensure that there is no central point of failure. - -In the case of a TraderMade outage voters can turn to any other available price feed API or a broker API, as the price feeds for the forementioned financial assets does not differ much between different providers. There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes. For this case, we provide options for additional price feed providers that voters could utilize. - -## Additional price feed providers - -### FXMarketAPI - -Documentation for the API can be found [here](https://fxmarketapi.com/documentation#live_rates). - -- Live price feed data -- Historical prices based on date and time -- Registration is free and provides 500 free requests -- Paid plans available -- OHLC request can be used to grab the last closing price before a weekend or a non-working day - -Example requests: - -- Live Rate for NZDUSD: `https://fxmarketapi.com/apiliveapi_key=api_key¤cy=NZDUSD` -- OHLC for a certain date on a currency pair: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=NZDUSD&date=2020-12-23&format=ohlc` -- Request for NZDUSD price at a certain date and time: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=NZDUSD&date=2020-12-23-15:50` - -### FCS API - -Documentation for the API can be found [here](https://fcsapi.com/document/forex-api). - -- 500 API Calls with Free Plan -- Live price data accessible with Free Plan - Updated every 60 seconds or less -- Historical data accessible with the Basic Paid Plan - 10$ per month - -Example requests: - -- Live Rate for NZD/USD: `https://fcsapi.com/api-v3/forex/latest?symbol=NZD/USD&access_key=api_key` -- Historical price for a certain date for NZD/USD - gives back the OHLC: `https://fcsapi.com/api-v3/forex/history?symbol=NZD/USD&period=1D&from=2020-12-23&to=2020-12-24&access_key=api_key` -- Price of NZD/USD between certain dates and times - gives a breakdown on the price each 1 minute between 12:00 and 12:30: `https://fcsapi.com/api-v3/forex/history?symbol=NZD/USD&period=1M&from=2020-12-23T12:00&to=2020-12-23T12:30&access_key=api_key` - -## Security considerations - -Adding this new identifier by itself poses a little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of NZDUSD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. diff --git a/research/uma/umips/UMIPs/umip-16.md b/research/uma/umips/UMIPs/umip-16.md deleted file mode 100644 index 9189c152..00000000 --- a/research/uma/umips/UMIPs/umip-16.md +++ /dev/null @@ -1,159 +0,0 @@ -# Headers -| UMIP-16 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add GASETH-1HR GASETH-4HR GASETH-1D GASETH-1W GASETH-1M as a price identifiers | -| Authors | Ali Atiia (@aliatiia), Matt Rice (@mrice32), Sean Brown (@smb2796) -| Status | Approved | -| Created | September 4, 2020 | - -## Summary (2-5 sentences) -The DVM should support requests for aggregatory gas prices on the Ethereum blockchain. - -## Motivation -The DVM currently does not support reporting aggregatory gas prices of finalized blocks on the Ethereum blockchain. - -Cost: Calculating an aggregatory statistic of gas prices on a confirmed block or range of blocks on the Ethereum blockchain is easy by virtue of the fact that all needed data is readily available on any Ethereum full node, whether run locally or accessed remotely through well-known providers such as Infura or Alchemy. Additionally, this data can be accessed through querying publicly accessible Ethereum blockchain data sets. - -Opportunity: Gas options/futures can help users and developers hedge against gas volatility allowing them to budget their gas consumption efficiently. Providing a price feed for settlement is a prerequisite. - -## Technical Specification - -The definition of this identifier should be: -- Identifier name: GASETH-1HR GASETH-4HR GASETH-1D GASETH-1W GASETH-1M -- Base Currency: ETH -- Quote Currency: GAS -- Sources: any Ethereum full node or data set of Ethereum node data -- Result Processing: Exact -- Input Processing: see Implementation section -- Price Steps: 1 Wei (1e-18) -- Rounding: Closest: N/A because the median algorithm and query as described below cannot produce numbers with higher precision than 1 Wei (1e-18). -- Pricing Interval: 1 second -- Dispute timestamp rounding: down -- Output processing: None -- Scaling Decimals: 18 (1e18) - -## Rationale - -The volatility of gas prices on Ethereum is a well-recognized problem that is only made worse by the ever increasing network congestion in recent months. This creates an opportunity for options/futures underwriters to create financial products that help decentralized applications (dApps) and their users hedge against gas price variability and have a consistent risk-minimized experience. The UMA protocol is well-positioned to provide the necessary plumbing for such products to flourish. Such products will need to rely on the DVM as a settlement layer in case of disputes. Therefore, by supporting data feeds for gas prices, the DVM opens the door for a win-win-win situation between financial products, users/dAaps, and the Ethereum network at large. - -Each transaction included in an Ethereum block pays an amount of Ether per 1 unit of gas consumed. That amount is (a) specified by a `gasPrice` parameter attached to a transaction, (b) is expressed in the smallest unit of the Ether currency which is `Wei`, and is set by the transaction submitter as a bid offered to the miners to have the transaction included. We therefore have a set of `gasPrice`s per block. - -There are two important factors to consider: (1) there is a block each 12-15 seconds in the Ethereum blockchain, and spikes in gas prices are routinely observed, and (2) miners can easily manipulate gas prices in a given block (especially in absence of a fee burn). Therefore, an aggregatory statistic needs to be computed over a sufficiently long range of blocks to proof against abnormalities whether due to extreme volatility or miner manipulation. We propose the median gas price over 1 hour (1HR), 4 hours (4HR), 1 day (1D), one week (1W), and 1 month (1M) periods _weighted by_ the gas used in a transaction. For safety and to proof against price manipulation and/or possible abnormal delays in block production, the DVM requires that a minimum number of blocks must have been mined within a given period. Otherwise, the DVM medianizes over a preset number of blocks defined in the following table: - -| Identifier | Minimum number of mined blocks | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| GASETH-1HR | 200 | -| GASETH-4HR | 800 | -| GASETH-1D | 4800 | -| GASETH-1W | 33600 | -| GASETH-1M | 134400 | - - -For example, if the GASETH-1HR is requested for `t1` = October 1st 2020 UTC 00:00:00, and the number of blocks mined between `t0` = September 30th 2020 UTC 23:00:00 and `t1` is less than 200, then the DVM medianizes over the 200 blocks mined at time <= `t1` regardless of how long (in wall clock time) it took for these blocks to be mined. - -## Implementation - -The total gas used by the blocks that were mined over the identifier specific time interval is computed. The identifier specific time interval is defined with bounds of the `timestamp` provided to DVM and the `timestamp` less 1HR (GASETH-1HR), 4HR (GASETH-4HR), 24HR (GASETH-1D), 168HR (GASETH-1W) or 720HR (GASETH-1M). Transactions in this range are also sorted by `total_gas_consumed`. - -The pseudo-algorithm to calculate the exact data point to report by a DVM reporter is as follows: - -```python -def return_median(t, N) - assert N in [1, 4, 24, 168, 720] - minimum_ranges = {1: 200, 4: 800, 24: 4800, 168: 33600, 720: 134400} # a mapping between the durations 1HR, 4HR, 24HR (1D), 168HR (1W), 720HR(1M) and the corresponding mimimum number of blocks that must have been mined within the period. - - # `t` is number of seconds since the epoch (unix time) - end_block = block.at(timestamp=t) # rounded down - offset = N - 3600*N # there are 3600 seconds/hour - start_block = block.at(timestamp=(t-offset)) - - # the DVM imposes a minimum number of blocks within a given time period to ensure safety against price manipulation - if end_block-start_block < minimum_ranges[N]: - start_block = end_block - minimum_ranges[N] - - total_gas, rolling_sum = 0, 0 - TXes = [] - - # loop over the block in the defined range starting with the least recent - for b in range(start_block, end_block, 1): - # gasUsed is in the header of each block - total_gas += b.gasUsed - for tx in b.transactions(): - gas_price = tx.gasPrice - gas_used = tx.totalGasUsed - TXes.append((gas_price, gas_used)) - - # sort transactions by gas_price ascendingly - sorted_TXes = sorted(TXes, key=lambda tup: tup[0]) - - for gas_price, gas_used in sorted_TXes: - rolling_sum += gas_used - if rolling_sum > total_gas/2: - return gas_price -``` - -An alternative method, for a DVM reporter to calculate this exact data point, would be to run the below SQL query against a public dataset of Ethereum node data such as Google BigQuery's `bigquery-public-data.crypto_ethereum.transactions` dataset. - -This query is parameterized with a UTC timestamp `t1`, a time range defined by the price identifier being used (i.e. 24HR) `N`, a lower bound of time `t2` defined by `t1 - N * 3600` and a minimum block amount `B` (explained in the *Rationale* section). - -```sql -DECLARE halfway int64; -DECLARE block_count int64; -DECLARE max_block int64; - --- Querying for the amount of blocks in the preset time range.

This is explained further in the *Rationale* section. - -These implementations are provided for explanation purposes and as convenient ways for DVM reporters to calculate the GASETH price identifiers. DVM reporters are free to develop additional implementations, as long as the implementations agree with the computation methodology defined in the *Rationale* section and specifications of the *Technical Specifications* section. - -## Security considerations - -Anyone relying on this data point should take note of the fact that manipulating the gas prices in a **specific** block or a short range of blocks is achievable by miners whether to inflate or deflate them for their own self-interest or on behalf of an attacker that bribed them to do so. The longer the range the requested statistic covers, the less the risk of manipulation is. This risk will also be significantly inhibited once [fee burn](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1559.md) is introduced in the Ethereum blockchain, because stuffing/padding blocks will have a non-zero cost even to miners (PoW) or block-producers (PoS). - -A large enough number of UMA governers should be running their full node to ensure data integrity. Relying on third-party full nodes presents a risk of manipulation of data, however if at least **one** governer is relying on their own full node, such manipulation is easily detectable. Hence, the security model here is 1-of-N which is low-risk. diff --git a/research/uma/umips/UMIPs/umip-160.md b/research/uma/umips/UMIPs/umip-160.md deleted file mode 100644 index 1a4bd2b4..00000000 --- a/research/uma/umips/UMIPs/umip-160.md +++ /dev/null @@ -1,142 +0,0 @@ -## Headers - -| UMIP-160 | | -| ---------------| --------------------------------------------------------------------------------------------| -| UMIP Title | Add COVENANT_V1 as a supported price identifier | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | April 22, 2022 | -| Discourse Link | [UMA's Discourse](https://discourse.umaproject.org/t/add-covenant-v1-price-identifier/1719) | - -# Summary - -The COVENANT_V1 identifier is intended to be used with an [Optimistic Distributor contract](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/financial-templates/optimistic-distributor/OptimisticDistributor.sol) to verify Covenant bribing protocol payouts.

The below listed key parameters will be used to instruct voters how to resolve a given price request for this identifier and request timestamp: - -- `votingPlatform`: Allows identifying on which platform bribed voters should participate. This can be either direct link to voting platform or human readable description. -- `voteProposal`: Includes all information required to identify the vote that is being bribed (human readable description). If required bribers can reference the next vote relative to the timestamp when the bribe had been first funded. -- `expirationTimestamp`: Provides ability for sponsors to claw back bribe if there is no finalized vote results available on the `voteProposal` after the set expiration timestamp. -- `bribedChoice`: Single voting choice that is covered by the bribe (e.g. YES/NO, asset in gauge proposal, etc.). -- `voteMeasurement`: Method for quantifying relative vote results for the bribed choice (from the `bribedChoice` parameter) expressed as a number ranging from 0 to 1 where 0 represents no votes and 1 means all voters had voted for the bribed choice. -- `payoutFunction`: Total payout function that defines how vote results value should be translated to total payout amount expressed as a multiplier to previously funded maximum bribe amount. This can be expressed either as formula or human readable instructions in case where more complex transformation logic is required. -- `bribeDistribution`: Bribe distribution rules to individual bribers. This should provide full instructions on: - - how to identify user addresses that have directly or indirectly (e.g. through delegation) voted on the `bribedChoice` in the `voteProposal`, - - conditions for disqualifying voters or applying minimum qualifying thresholds to user voting power, - - how to distribute bribe payout among qualifying voters, - - if and what fee amount to delegates should be applied for voters having delegated their voting power. -- `clawback`: Instructions on where to distribute the difference between maximum bribe amount and actual total payouts to voters. This can be either single recipient address or instructions on how to distribute it based on who has funded the bribe (e.g. only the first sponsor creating the bribe or proportional distribution among all sponsoring addresses if the bribing rewards had been topped). -- `errorMargin`: Numerical value representing the maximum allowed error margin (expressed as coefficient) when validating individual payouts. -- `rewardIndex`: Integer value allowing to identify `Reward` struct from the Optimistic Distributor contract that includes the maximum bribe payout. - -Whenever any of the parameters above require longer descriptions they can be hosted on IPFS and their content hash string used as parameter value instead. - -### Example ancillary data - -As an illustration one could construct bribe for QiDao Vault Incentives Gauge with following ancillary data parameters: - -``` -votingPlatform: "https://snapshot.org/#/qidao.eth", -voteProposal: "Next Vault Incentives Gauge round following the initial funding as emitted by requesting contract in RewardCreated event with matching rewardIndex.

If any of **must** conditions in this UMIP is not fulfilled the proposed payout should be considered invalid. If the proposed payout is invalid, the price should be `0`. If the proposed payout is valid, the price should be `1`. *Note*: all price values should be scaled by `1e18` if responding programmatically, but Optimistic Oracle and Voting dApps scales them for the users. - -Price requests for `COVENANT_V1` price identifier should be only made through Optimistic Oracle since its resolvement requires verifying event data emitted by the Optimistic Distributor contract in the same transaction when the price is requested to the Optimistic Oracle. In case of dispute UMA voters would need to identify this original price request transaction through the stamped `ooRequester` and `childChainId` parameters to the ancillary data. - -Since the functioning of `COVENANT_V1` price identifier relies on the hard-coded protocol fee recipient address the price request **must** originate only from Polygon deployment of the Optimistic Distributor contract. - -Voters should first resolve all ancillary data parameter values either directly or through the included IPFS content hash strings. In case any of the required parameters (all listed in the Ancillary Data Specifications section except for `clawback` and `errorMargin`) is missing or their values/instructions cannot be interpreted unambiguously bribe should be refunded to its sponsor and voters should validate such price request against instructions in the Refund instructions section (though Technical verification still applies). - -## Status of bribed vote proposal - -1. Identify the voting proposal being bribed from the `votingPlatform` and `voteProposal` parameters. -2. Determine whether the voting proposal being bribed had been opened for voting and irreversibly resolved at or before the cut-off time from the `expirationTimestamp` parameter. In case the vote was not resolved on time the bribe should be refunded to its sponsor and voters should validate such price request (made after `expirationTimestamp`) against Refund instructions section. -3. If the price request was made at or before the cut-off time from the `expirationTimestamp` the voting proposal being bribed **must** have been irreversibly resolved at or before the `expirationTimestamp`. This condition also applies when the voting proposal had been withdrawn and the proposal to refund the briber can be made only after the `expirationTimestamp`. - -## Technical verification - -This section provides instructions to verify if the proposed payout distribution matches the provided bribe funding and all individual payouts include valid Merkle proofs verifying them against the proposed Merkle root. - -1. Collect data on the proposed bribe payout distribution by inspecting `rewardToken`, `maximumRewardAmount`, `merkleRoot` and `ipfsHash` parameters emitted by the Optimistic Distributor contract in the same transaction when price was requested on the Optimistic Oracle. -2. `ipfsHash` **must** represent a valid IPFS content hash for the IPFS hosted file listing actual bribe payouts. -3. Bribe payouts file referenced by `ipfsHash` **must** contain at least a list of bribe payout recipient addresses, individual bribe amounts and their Merkle proofs (array of `bytes32` values represented as hex strings) for each recipient. -4. Sum of individual bribe amounts in the bribe payout file **must** exactly match the `maximumRewardAmount` (as it also includes the remainder to be returned to the sponsor). It is expected that by default bribe payouts are raw amounts that do not need any scaling and can be directly compared to the value of `maximumRewardAmount`. Though, in case human readable payouts were provided voters should first scale them up to their raw representation using the `decimals` parameter from the `rewardToken` contract. -5. It is expected that the bribe payout file includes `accountIndex` parameter for each recipient and they **must** be unique non-negative integers across all payout set. If `accountIndex` is not provided then voters should assign it continuously for each recipient starting from 0. -6. Calculate leaf data for each individual bribe payout by taking Keccak-256 hash over the ABI converted and tightly packed parameters of recipient address, bribe amount and `accountIndex`. In `web3.js` this can be achieved by using: - - ``` - web3.utils.soliditySha3( - { value: recipientAddress, type: "address" }, - { value: bribeAmount, type: "uint256" }, - { value: accountIndex, type: "uint256" } - ); - ``` -7. Verify each individual bribe payout by traversing a Merkle tree up from its leaf (calculated is Step 6 above) using its corresponding Merkle proofs: - - The process should start by taking the leaf and the first element of the Merkle proofs array. - - Order both above from lowest value to highest and concatenate them to get `bytes64` value. - - Perform Keccak-256 hash on the concatenated `bytes64` to get the next Merkle branch. In `web3.js` one can use `web3.utils.soliditySha3` method. - - Continue by taking the next element from the Merkle proofs array, pair it with the obtained Merkle branch from the previous step and Keccak-256 hash their ordered concatenation to get the next Merkle branch. - - Repeat the above procedure for all elements of the provided Merkle proofs array. The last obtained hash **must** exactly match the `merkleRoot` for all individual bribe payments. - -## Economic verification - -This section provides instructions to verify proposed payout amounts against expected bribe amounts following provided instructions from ancillary data except for cases when bribe should be refunded to the sponsor(s). - -1. Follow instructions passed from the `voteMeasurement` parameter to quantify the voting results for the bribed choice (from `bribedChoice` parameter). If the voting proposal does not include the bribed choice the result should be resolved to 0. In any case the results of following `voteMeasurement` instructions should be floored at 0 and capped at 1. -2. Follow the instructions passed from the `payoutFunction` (or apply the formula) to convert obtained voting results to payout amount expressed as a multiplier to previously funded maximum bribe amount. In any case the results should be floored at 0 and capped at 1. -3. Multiply the obtained value above with the `maximumRewardAmount` and round it to the nearest integer to obtain gross payout (before fees) in raw units of `rewardToken`. -4. Subtract the calculated gross payout above from the `maximumRewardAmount` to obtain claw-back amount claimable by the bribe sponsor(s): - - In case `clawback` parameter is provided in ancillary data and it contains a single address then assign the calculated claw-back amount to this address. - - If `clawback` parameter provides other instructions, follow them to assign how claw-back amount should be distributed among sponsors. - - If `clawback` parameter is missing or its value cannot be interpreted unambiguously then by default entire claw-back amount should be assigned to the original sponsor funding the the bribe. This can be obtained by calling `rewards` method on the Optimistic Distributor contract with the `rewardIndex` from ancillary data as input parameter. The obtained `Reward` struct will contain the `sponsor` address as its second element. Note that in case other sponsors have topped up the bribe by funding the same `rewardIndex` with the `increaseReward` method they would not receive any clawed-back bribe amounts. -5. Calculate protocol fee as 2% from gross payout amount in rounded raw units of `rewardToken`. Assign Covenant protocol fee collector address 0x104E3a4FbbDdf02843f30ADF145F661f68Afd1F4 on Polygon as its recipient. -6. Calculate total net payout to users by subtracting protocol fee amount from the gross bribe payout. -7. Follow the instructions passed from the `bribeDistribution` parameter to assign net bribe amount calculated above to individual recipients. This should involve: - - Identify user addresses and their voting power that have directly voted for the `bribedChoice` in the bribed `voteProposal`. - - If instructed, exclude any disqualifying recipients (e.g. due to split-vote or minimum voting threshold). - - Assign part of net bribe payout to direct voters based on provided instructions (e.g. proportional to voting power, any maximum payout limits to individual users, equal to all qualifying voters, etc.). - - If instructed, identify users that had delegated their voting power and assign their net bribe amounts from the previously calculated delegate bribe. If instructed apply the provided delegation fee to be held by the delegates. - - Apply any other instructions provided in the `bribeDistribution` parameter. This can involve rules for distributing any remainder from total payout in case any qualifying conditions or maximum payout limits to individual users have been applied (e.g. how to split it among other users or just reducing total payout amount and adding them to sponsor's claw-back amount). -8. Compile the expected bribe payout amount list by recipient addresses including sponsor(s) claw-back (Step 4), protocol fee recipient (Step 5) and voters/delegates (Step 7). -9. Validate proposed payouts (as verified in the Technical verification section) against expected payouts from Step 8: - - All recipient addresses in the proposed payout file **must** have a matching recipient from expected payouts, though some of smaller expected payouts could be excluded in the proposed payout file due to rounding. - - For each individual address recipient from the proposed payout file calculate the modulus for its proposed payout amount (in raw units of `rewardToken`) difference with the expected payout for the same address and divide it over its expected payout. This coefficient **must** not exceed the maximum allowed error margin passed as `errorMargin` parameter. If `errorMargin` is not provided in ancillary data then fall back to default allowed error margin of `0.0001` for this comparison. - -## Refund instructions - -In case required ancillary data parameters are missing or their values/instructions cannot be interpreted unambiguously the bribe should be refunded to its sponsor(s). This also applies in cases when the bribed vote has not been resolved (or has been withdrawn altogether) at or before the `expirationTimestamp`. In these scenarios one should perform the instructions in the Economic verification section as if the `payoutFunction` in Step 2 resulted in value of 0 and entire `maximumRewardAmount` should be distributed only among bribe sponsor(s) (identified in Step 4). Also, such refund proposal should be verified against the Technical verification section. - - -## Security considerations - -The security of this price identifier is highly dependent on bribers providing unambiguous instructions through ancillary data parameters. In order to mitigate this it is expected that Covenant bribing market operator would impose restrictions on standard allowed ancillary data parameters through its front-end. - -In order to ensure right incentives for independent verifiers to check proposed bribe payouts the operator of Covenant bribing market should impose adequate Optimistic Oracle bond amounts and liveness periods that are consistent with the complexity of expected verification operation. - -Users of this price identifier should be aware that IPFS storage on itself does not guarantee persistent data availability. Even though the operator of Covenant bribing market would attempt to ensure data availability within reasonable time period users can provide pinning of linked IPFS files on their nodes or at least save a local copies of files linked in ancillary data and Merkle proofs for claiming the payouts. - -Bribers of Covenant protocol should be aware that not all voting platforms enforce that vote results directly translate to transaction execution on-chain and might require certain trust assumptions on the organizers of the vote to execute it properly. The execution risk hence is outside the scope of this price identifier that tracks only the resolved voting scores and payouts to individual voters. diff --git a/research/uma/umips/UMIPs/umip-161.md b/research/uma/umips/UMIPs/umip-161.md deleted file mode 100644 index 22127f79..00000000 --- a/research/uma/umips/UMIPs/umip-161.md +++ /dev/null @@ -1,49 +0,0 @@ -**UMIP-161** - -- **UMIP title:** Add MAGIC as collateral currency -- **Author:** Mr.Bahama -- **Status:** Approved -- **Created:** 26 May 2022 - -## Summary (2-5 sentences) - -This UMIP proposes adding MAGIC for use as collateral in UMA contracts. - -## Motivation - -MAGIC token is economic infrastructure for various play-to-own games using TreasureDAO.

This will enable the implementation of a more robust and adaptable price requests. - -## Motivation -Prior to the addition of this Optimistic Oracle, callbacks were executed whenever they were present in the requester contract, without the ability to control when this occurred.

SPACs have only a limited period during which they may consummate a Business Combination, generally not exceeding 24 months. A SPAC generally focuses upon one industry or sector, but may maintain flexibility to engage in transactions in other industries or sectors if necessary or appropriate. More information about SPACs can be found [here](https://spac.guide/spacbasics/) and [here](https://www.spacanalytics.com/).

-A good way to capitalize on such momentum growth without having to analyze hundreds of SPACs is to take advantage of the movement of the index value that includes stocks of the most active SPACs.
- -The selection of **10** stocks of the most active SPACs included in the basket of the proposed uSPAC10 index is made according to [spacHero database top-10 gainers](https://www.spachero.com/). spacHero is a free SPAC resource for retail investors. [**spacHero – Rapidapi.com**](https://rapidapi.com/spachero/api/spachero-spac-database/) is an official spacHero SPAC API with live rankings, SPAC target names, merger meetings, warrant redemption deadlines, price targets, SEC filings, investor presentations and more.

- ->**Rapidapi.com** Finance APIs allow end-users a variety of service options for their accounts as well as to stay current on events and news that impact their portfolios and financial security. For example, a finance API could remotely connect them to their bank account to initiate deposits, transfers, or other transactions. Other financial APIs include stock market news and trading platforms, cryptocurrency markets, and more. A financial API provides a secure link from a consumer to the databases and transactional servers of the institutions with which they do business. Application programming interfaces, or APIs, are the digital links between data providers and end-users. In the financial sector, security is essential as sensitive information is transferred in real-time, so only the most robust protocols are utilized to protect the data transmitted on both ends.

- -### Weekend timestamp -Over the weekend or some official holidays the REST API does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). -Due to unavailability of price feed for stock exchange rates over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. -If a request timestamp takes place on a weekend or any other day the stock market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. -### Stock markets working hours -Underlaying assets trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. -### Price feed -Our price-feed provider’s API documentation can be found [here](https://rapidapi.com/sparior/api/mboum-finance).
-A reference price feed implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/unisxapp/protocol/blob/USPAC5PriceFeed/packages/financial-templates-lib/src/price-feed/DefaultPriceFeedConfigs.ts)
-"Mboum Finance – Rapidapi.com" is provided as an accessible source to query for this data, but ultimately how one queries for these rates should be varied and determined by the voter to ensure that there is no central point of failure.
-In the case of a "Mboum Finance – Rapidapi.com" outage voters can turn to any other available price feed API or a broker API, as the price feeds for the forementioned financial assets does not differ much between different providers. There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes. For this case, we provide options for additional price feed providers that voters could utilize. -### Additional price feed providers -- **Quotient – Rapidapi.com**

The Decentra-List dapp allows users to add and remove addresses from a list based on the list creator's set of criteria. When a revision to the list is proposed, Decentra-List verifies the revision meets the list criteria by creating a price request with the `DECENTRA-LIST` price identifier and proposing the price.

The proposed revisions are then sent to the Optimistic Oracle for verification that they meet the list criteria. The price requests sent to the Optimistic Oracle only verify that the proposed revision is correct as per the list criteria. It does not verify that addresses on the list not included in the revision are correct, nor does it verify that the current revision includes all addresses that should be added or removed from the list. - -It is intended that Decentra-List will only execute revisions that are provably correct as per the list criteria. As such, there are only 2 price return values provided: `1` is used for revisions that are provably "YES" and will be executed by Decentra-List and `0` is used for "NO" or "CAN NOT BE DETERMINED" and Decentra-List will reject revisions with this returned price value. - -Every Decentra-List price request to the Oracle will start with a question, either "Do all Proposed Addresses meet the List Criteria?", or "Do all Proposed Addresses fail to meet the List Criteria?", depending on whether the proposed revision is to add or remove addresses to the list. These questions have been constructed so that every single address must be a "YES" for the correct Oracle response to be "YES" or `1`. For example, if a Decentra-List user proposes a revision that would add 4 addresses to the list where 3 addresses meet the criteria, but 1 address does not, the correct Oracle response would be `0` and the revision would be rejected by Decentra-List with no new addresses added to the list. - -Whether an address meets a list's criteria may change over time. Proposed Addresses should be evaluated against the list criteria at the timestamp of the price request. To make this clear, the question posed in the ancillary data includes, "at the time of the price request". - -# Implementation - -1. Voters should decode the ancillary data to get the list criteria and the Revision ID needed to get the list of Proposed Addresses. -2. Voters should find the array of Proposed Addresses as below: - - Navigate to the Decentra-List dapp, select the network of the price request and connect their wallet. - - Select the List address from the drop down to display information about that List. The List address can be found in the requester field of the oracle price request. - - Open the Pending Revisions drop down and find the Proposed Addresses for the Revision ID provided in the Oracle price request ancillary data. -3. Voters should evaluate the array of Proposed Addresses against the List Criteria provided in the ancillary data to answer the question provided in the ancillary data. The List Criteria provided in the ancillary data could contain directions on data sources, verification scripts, etc. If so, that information should be used. Otherwise, the voter should determine how to verify whether the Proposed Addresses meet the given List Criteria. -4. Voters should return `1` if the answer to the question in the ancillary data is provably "YES". Voters should return `0` if the answer to the question is "NO" or "CAN NOT BE DETERMINED". - -# Security Considerations - -This construction allows Decentra-List users flexibility in creating new lists with custom criteria, bond amounts and liveness periods. The list criteria will be used for all revisions to the list and can not be edited. List creators should be careful to construct the list criteria, so a deterministic outcome can be reached for all Proposed Addresses. List creators should also be careful to set the bond amount and liveness period large enough to provide disputers sufficient time and financial incentive to review all Proposed Addresses (up to 99 addresses can be included in a single revision). - -There are also potential contract-level attacks that could result from people intentionally setting up Decentra-List lists dishonestly to their advantage. As a rule, any contracts that reference a Decentra-List list smart contract, should review the list properties and this UMIP beforehand. diff --git a/research/uma/umips/UMIPs/umip-17.md b/research/uma/umips/UMIPs/umip-17.md deleted file mode 100644 index d44ff428..00000000 --- a/research/uma/umips/UMIPs/umip-17.md +++ /dev/null @@ -1,60 +0,0 @@ -## Headers -| UMIP-17 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add rDAI as a collateral currency | -| Authors | Jeff Bennett (endymionjkb@gmail.com), Sean Brown (@smb2796) | -| Status | Approved | -| Created | September 25, 2020 | - -## Summary (2-5 sentences) -This UMIP will add rDAI (redeemable Dai) to the supported collateral currencies to the AddressWhitelist contract, allowing UMA users to mint synthetics using rDAI as the collateral currency. This UMIP will also add a flat final fee to charge per-request. The proposed final fee is 400 rDAI per request. - -## Motivation -One of the most basic use cases for synthetic tokens is derivitives tied to underlying real-world assets, including equities - and a popular way to gain exposure to equities is through ETFs or index funds: baskets of securities chosen according to a published set of criteria. - -Increasingly, and particularly among millennials, those criteria involve moral judgments and values. "Value driven investment" funds (e.g., the ETHO Climate Leadership Index) represent a rapidly rising trend in the industry, and often outperform the broader market. - -An UMA synthetic tied to an "ESG" index would be a great way to "long the environment." But an even greater way would be to use rDAI as collateral for the index position, designating an environmental charity (e.g., Offsetra or rTrees) as the beneficiary. That way, the charity always benefits, even if the index underperforms. (Perhaps especially then, if position holder needs to deposit more rDAI to avoid liquidation.) - -Of course, this idea can be generalized beyond ESG, to any pairing of a charitable cause to a related ETF or index fund. And since new charities are partnering with rDAI all the time - in fact, through the rDAI protocol anyone can create an arbitrary "charity" simply by providing a list of ETH addresses and weights - this is a growth industry. - -A local charitable organization could create a monthly "rolling" synthetic that directed funds according to the organization's priorities that month, either by altering weights, or by creating a new list of beneficiaries. - -Alternatively, the protocol also allows rDAI to be used without specifying charitable beneficiaries at all. Undesignated ("self-hat") rDAI could be used simply to offset potential losses and de-risk positions, as the collateral would naturally increase over time. Hybrid positions are also possible; e.g., 50% going to charity, and 50% compounding within the synthetic. - -When using undesignated ("self-hat") rDAI as collateral for the EMP contract template, a contract sponsor would need to set `excessTokenBeneficiary` to an address they wish to receive the accrued rDAI interest. The EMP function trimExcess would then need to be called to drain the excess collateral to the `excessTokenBeneficiary`. See below for possible security implications of this approach. - -## Technical Specification -To accomplish this upgrade, two changes need to be made: -- The rDAI address, [0x261b45d85ccfeabb11f022eba346ee8d1cd488c0](https://etherscan.io/token/0x261b45d85ccfeabb11f022eba346ee8d1cd488c0) on Mainnet, needs to be added to the collateral currency AddressWhitelist introduced in UMIP-8. - (This is the address of the proxy contract, which is the token that gets transferred.) -- A final fee of 400 rDAI needs to be added for rDAI in the Store contract. -## Rationale -This change encourages wider adoption of the UMA protocol through strengthening ties with traditional financial markets, and promoting a new use case: securing synthetic positions with interest-bearing collateral that benefits charities related to the underlying assets. - -It also provide general utility by enabling the use of "compounding collateral," which serves to lower risk, offset losses, and monetize "HODLing" of inactive synthetic positions (as the first such tokens are likely to be), or those with far future expiration dates. -400 rDai was chosen because the current final fee for DAI is 400 DAI and the value of rDAI is directly equal to the value of DAI. -## Implementation -This change has no implementation other than adding the rDAI address to the collateral currency AddressWhitelist and adding the rDAI final fee to the Store contract. - -## Security considerations - -rDAI collateral providers should do their own due diligence on the beneficiaries of any given synthetic before opening a position. This is easy to do on a technical level, since all the "hat"-related information, including the literal Ethereum addresses of recipients, is available on-chain through the token contract interface and corresponding subgraph. (Not to mention the graphical rDAI explorer.) rDAI held in positions would be tamper-proof, as it is owned by the synthetic contract. These addresses (ideally linked to ENS domains) could then be verified through the official web sites of the charitable organizations. -rDAI itself should present very little risk. It is an ERC-20 token based on DAI, and the project was audited by Quantstamp: -https://certificate.quantstamp.com/full/r-token-ethereum-contracts - -The "logic" contract referenced by the proxy is also upgradeable, in case any issues are found. rDAI is hard-pegged to DAI, so in that sense is as safe to hold as DAI. - -One of the intended uses of rDAI collateral is in support of synthetics based on ESG (or other value driven investment strategies aligned with supported charities), and this not been a common use case. So far, most synthetics (e.g., those issued by UMA) have been crypto-pairs enabling leveraged positions, or simple yield instruments such as uUSD. - -Market liquidity for these new instruments will likely be low at first, and there may be insufficient DVM participation to ensure the solvency of positions. Investors would also be dependent on published financial data for the underlying ETFs (constituents, weights, and prices), which is less available and reliable than, say, the ETH-BTC price. These synthetics may therefore be riskier than other types of synthetics, and those minting such contracts should take care to set appropriate collateralization requirements, perhaps based on the measured volatility of the underlying indices. - -However, this is not the only use case for rDAI in synthetics. Simply using it for compounding collateral is even "safer" than DAI itself, as the collateralization ratio would gradually increase, with no action required from the position holder (other than calling the function to apply accrued interest). - -Note that the expected behavior - directing interest on all future positions to the "advertised" hat, which is the stated purpose of and motivation for users of the synthetic - depends on separate calls to the rDAI and UMA protocols, and this introduces order dependencies and timing considerations. - -The hat inheritance feature of rDAI ensures that all rDAI deposited through opening positions will adopt the hat associated with the contract address, and this gets assigned the first time rDAI is transferred to the contract. So in order to set the contract's hat, the creator must open an initial position, sending in rDAI with the "advertised" hat, using a three-step mint/deploy/deposit process. If the last two steps are not done atomically, an attacker could "hijack" the synthetic by opening a position before the creator, with the hat set to the attacker's wallet - in which case all interest would go to the attacker instead of the charity. - -As described above, a creator could implement a "management fee" - capturing a portion of all interest payments - by either setting one of the recipients in the hat to an account controlled by the creator (in which case `payInterest` would directly transfer funds), or by setting one of the recipients to the contract address and `excessTokenBeneficiary` to the wallet address (in which case `payInterest` would transfer rDAI to the contract, and the creator could withdraw it with `trimExccess`). In the latter case, the minter needs the EMP contract address, so the process would be deploy/mint/deposit, all of which should be done atomically. (Technically, the EMP contract address could be precomputed using the deployer address and nonce, in which case the creator could still use the regular mint/deploy/deposit sequence.) - -In any case, the hat id and recipient addresses assigned to an address are publicly visible, so if such an attack did occur, it could be easily discovered, and avoided by simply abandoning the contract. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-170.md b/research/uma/umips/UMIPs/umip-170.md deleted file mode 100644 index b6a79b4d..00000000 --- a/research/uma/umips/UMIPs/umip-170.md +++ /dev/null @@ -1,102 +0,0 @@ -## Headers - - -| UMIP-170 | | -| -------------- | ------------------------------------------------------------------------ | -| UMIP Title | Add `ASSERT_TRUTH` as a supported price identifier | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | January 30th, 2023 | -| Discourse Link | https://discourse.umaproject.org/t/feat-add-assert-truth-identifier/1900 | - -# Summary - -The DVM should support price requests for the `ASSERT_TRUTH` price identifier. `ASSERT_TRUTH` is intended to be used as - a default price identifier for UMA's [Optimistic Oracle V3 contract](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/optimistic-oracle-v3/implementation/OptimisticOracleV3.sol) - that allows asserters to make claims about the state of the world.

To this end, the result of an assertion can only be true or false, and an assertion is resolved only after the liveness period has expired or, in the case of a dispute, after it has been settled in the Oracle.

The identifier will simplify complex event settings and ensure accurate management and recording. - -## Technical Specification - -To accomplish this upgrade, a few actions will need to be taken: - -- A new `OptimisticOracleV3` contract has been re-deployed in the following networks: - - - Mainnet: [0xfb55F43fB9F48F63f9269DB7Dde3BbBe1ebDC0dE](https://etherscan.io/address/0xfb55F43fB9F48F63f9269DB7Dde3BbBe1ebDC0dE) - - Polygon: [0x5953f2538F613E05bAED8A5AeFa8e6622467AD3D](https://polygonscan.com/address/0x5953f2538F613E05bAED8A5AeFa8e6622467AD3D) - - Optimism: [0x072819Bb43B50E7A251c64411e7aA362ce82803B](https://optimistic.etherscan.io/address/0x072819Bb43B50E7A251c64411e7aA362ce82803B) - - Arbitrum: [0xa6147867264374F324524E30C02C331cF28aa879](https://arbiscan.io/address/0xa6147867264374F324524E30C02C331cF28aa879) - - Boba: [0xe1C2587C1789f7D00F22931D4DBAD537405DFe1f](https://bobascan.com/address/0xe1C2587C1789f7D00F22931D4DBAD537405DFe1f) - -- Transactions will need to be proposed to add this new addresses to the `Finder` contract under the name `OptimisticOracleV3` in each network. This is how other contracts will find the optimistic oracle and reference it. -- The new `OptimisticOracleV3` will need to be registered with the `Registry` in each network so that it can make requests to the DVM. -- The old `OptimisticAsserter` contract will need to be unregistered in the `Finder` in each network. This will prevent it from being used in the future. - -Note: this change will only add the `OptimisticOracleV3` to the networks mentioned above. New contracts that utilize the `OptimisticOracleV3` will need to be deployed for it to become useful. Until all steps above are performed, the deployed `OptimisticOracleV3` _should not_ be used in production since it will not be able to raise disputes to the DVM. - -This [script](https://github.com/UMAprotocol/protocol/blob/master/packages/scripts/src/upgrade-tests/register-new-contract/1_Propose.ts) will generate the mainnet transactions required to register the aforementioned contracts in their respective Registry and Finder, and will include them in the UMIP proposal. - -## Implementation - -The `OptimisticOracleV3` contract can be found [here](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/optimistic-oracle-v3/implementation/OptimisticOracleV3.sol). The `OptimisticOracleV3` contract, previously known as `OptimisticAsserter`, has been audited by OpenZeppelin. The audit report can be found [here](https://blog.openzeppelin.com/uma-optimistic-asserter-audit/). - -The code updates necessary for this update can be found in the following pull requests on GitHub: - -- https://github.com/UMAprotocol/protocol/pull/4413 -- https://github.com/UMAprotocol/protocol/pull/4440 - -Due to the nature of this modification, it was determined that a new audit was not necessary as the change only renames the contract to `OptimisticOracleV3` and adds an identifier to the event and does not impact the existing functionality of the code . The update has been thoroughly reviewed and tested, and is ready for deployment. - -## Security considerations - -The `OptimisticOracleV3` only has the ability to send price requests to the DVM, so in the event of a serious bug, the biggest security implication would be that end-users would be able to send requests to the DVM without paying the final fee. diff --git a/research/uma/umips/UMIPs/umip-173.md b/research/uma/umips/UMIPs/umip-173.md deleted file mode 100644 index a2811bf0..00000000 --- a/research/uma/umips/UMIPs/umip-173.md +++ /dev/null @@ -1,127 +0,0 @@ -## Headers - -| UMIP-173 | | -| ---------- | --------------------------------------------------------------------------------------------------------------------- | -| UMIP Title | Approve DVM upgrade to DVM2.0 | -| Authors | Chris Maree (chris@umaproject.org), Pablo Maldonado (pablo@umaproject.org), Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | October 26, 2022 | -| Discussion | [Discourse](discourse.umaproject.org/t/approve-dvm-upgrade-to-dvm-2-0/1935) | - -## Summary - -This UMIP proposes an upgrade to the UMA Data Verification Mechanism (DVM) that re-works core parts of UMA's tokenomics. -At a high level, this upgrade adds a new staking and slashing mechanism wherein voters earn a pro-rata share of emissions -for staking and are slashed for voting wrong (or not voting). This upgrade also re-works a number of other DVM contracts -such as an updated governor, proposer contract and new designated voting contract. Finally, this upgrade has a new -emergency recovery mechanism to the DVM that enables emergency admin proposals to bypass the DVM's schelling point -oracle system in the event of an emergency. More detail on the individual changes are broken down in the sections that -follow. - -## Motivation & Rationale - -The current UMA tokenonomics suffers from a few issues that the proposed upgrade aims to address: - -1. The current system has a flaw wherein an attacker can create spurious votes with the intention of capturing UMA inflation - rewards. This becomes an issue when the rewards a voter receives exceed the cost of the final fee (currently ~$500). - In practice, this means that you need to be voting with ~72k UMA (at an UMA price of $2.25 and considering average vote - participation over a number of recent votes) to profit from creating spurious votes. - -2. It is currently hard to work out the APY a voter receives for participating in the UMA system. One needs to consider - the number of other UMA involved in votes and, crucially, estimate how many voting rounds per period of time there will be - to work out an implied APY. This is difficult as the number of requests (and the resultant emissions) changes depending - on externalities that can't easily be modelled. This also poses complexities when working out the UMA inflation over time as - it is so dependent on the number of requests. Ideally, the UMA supply inflation (and the associated voter APY) are easy - to find and are not a function of the number of requests. - -3. The current UMA tokenomics does not distinguish between price requests and governance actions. Ideally, the DVM - should treat governance actions as democratic and avoid the schelling point penalty for voting against the majority in these - requests. - -4. Today the DVM has no way of enforcing dynamic rewards for participation depending on dynamics of a given vote. - For example, we might want to penalize non-participation more if a vote is contentious. Ultimately, it would be useful to - have a more flexible mechanism for the conditions under which a voter is rewarded (or punished.) - -5. Lastly, the current UMA tokenomics does not incentivize the locking up (staking) of UMA. The DVM and UMA token interplay - should drive up the UMA token price through the removal of liquid UMA through a staking mechanism. This should also make - UMA more anti-fragile to price shocks and general market movements through the removal of liquidity. Additionally, the - current UMA system is not resistant to an adversarial take over as as soon as someone is able to capture the control - of the DVM and use it to vote an incorrect outcome they can dump UMA on the open market before the cost of corruption - comes in to effect (the attacker has a time advantage over other market participates to react). - -The proposed upgrade aims to address all of the identified issues, as well as adding in some additional nice-to-haves. A -full list of the functionality change is listed below: - -1. New DVM participation incentives: - 1. Staking rewards are emitted at a constant rate per second. This means you can work out the overall UMA inflation over time and stakers can easily work out their APY for staking in the system. This emission is shared pro-rata among all stakers. - 2. Slashing mechanism that redistributes tokens from inactive and wrong voters to the stakers who have resolved the vote correctly. This hardens the schelling point by adding a more punitive cost function with being wrong. - 3. Dynamic slashing library that can configure the amount slashed as a function of vote participation metrics. For example, the system could be configured to slash non-participates more highly the more contentious a vote is. The configuration of this module is left up to UMA governance and can be changed later via a DVM vote. - 4. Governance votes are treated as a special price request category where slashing mechanism is not applied. -2. Automatic spam protection mechanism where any non-governance votes that do not meet required participation and - agreement thresholds for a number of rounds (set by UMA governance) would be deleted. This allows voters to create a - schelling point around treating a request as spam by not voting on it. -3. Recovery mechanism where bonded emergency proposals can be executed short-circuiting the normal voting mechanism. This enables the DVM to recover from any kind of internal failure mode that could occur (breakage in the commit reveal system, contract issues or other) through a permissionless upgrade flow. -4. First class vote delegation support enabling a 1 to 1 relationship between the delegator and delegate wallets. This lets a voter delegate from a secure cold storage wallet to a hot wallet. The hot wallet can commit, reveal and claim and re-stake their rewards but can't access the underlying stake. More complex delegation systems (e.g. pooled UMA staking with delegate voting) can be built on top of this externally to the core UMA contracts, if desired. -5. Governance proposals can now include ancillary data, allowing for better identifying information to be included with vote proposals. -6. Price requests now contain a unique identifier, enabling easier tracking and support in front ends. -7. A number of gas optimizations were made throughout the protocol. - -## Implementation & Technical Specification - -This UMIP upgrades the following contracts in the UMA DVM system: - -1. Core DVM voting contract: `Voting.sol` → `VotingV2.sol` (implementation [here](https://github.com/UMAprotocol/protocol/blob/3ad31b3aab3cf342f6a91dce54032fe0ee1b15c8/packages/core/contracts/data-verification-mechanism/implementation/VotingV2.sol)). -2.

New `FixedSlashSlashingLibrary.sol` that calculates the amount of tokens to slash for not voting or voting wrong (implementation [here](https://github.com/UMAprotocol/protocol/blob/3ad31b3aab3cf342f6a91dce54032fe0ee1b15c8/packages/core/contracts/data-verification-mechanism/implementation/FixedSlashSlashingLibrary.sol)). - -**The associated deployments for these contracts can be found in this table:** -| **Contract Name** | **Deployment Address** | -|---------------------------------|------------------------| -| `VotingV2.sol` | [0x004395edb43EFca9885CEdad51EC9fAf93Bd34ac](https://etherscan.io/address/0x004395edb43EFca9885CEdad51EC9fAf93Bd34ac) | -| `ProposerV2.sol` | [0x50efaC9619225d7fB4703C5872da978849B6E7cC](https://etherscan.io/address/0x50efaC9619225d7fB4703C5872da978849B6E7cC) | -| `EmergencyProposer.sol` | [0x91F1804aCaf87C2D34A34A70be1bb16bB85D6748](https://etherscan.io/address/0x91F1804aCaf87C2D34A34A70be1bb16bB85D6748) | -| `GovernorV2.sol` | [0x7b292034084A41B9D441B71b6E3557Edd0463fa8](https://etherscan.io/address/0x7b292034084A41B9D441B71b6E3557Edd0463fa8) | -| `FixedSlashSlashingLibrary.sol` | [0x9a406ba5a99983250fd663947b3c968d387ce5cd](https://etherscan.io/address/0x9a406ba5a99983250fd663947b3c968d387ce5cd) | - -**The deployment parameters used are defined below:** -| Key | Value | -|--------------------------|--------------------------------------------| -| `emergencyQuorum` | 5000000.0 | -| `emergencyExecutor` | 0x8180D59b7175d4064bDFA8138A58e9baBFFdA44a | -| `emergencyMinimumWaitTime` | 864000 | -| `baseSlashAmount` | 0.001 | -| `governanceSlashAmount` | 0.0 | -| `emissionRate` | 0.0 | -| `unstakeCooldown` | 604800 | -| `phaseLength` | 86400 | -| `gat` | 5000000 | -| `spat` | 0.5 | -| `maxRolls` | 4 | -| `maxRequestsPerRound` | 1000 | -| `proposerV2DefaultBond` | 5000.0 | -| `votingUpgraderAddress` | 0x13852D4AF390d8C3404c0577fd8B8E43389A290b | - -The proposed upgrade process involves a number of steps and is described in detail [here](https://github.com/UMAprotocol/protocol/blob/master/packages/scripts/src/upgrade-tests/voting2/readme.md). The upgrade involves proposing a number of upgrade transactions to the DVM that are then executed. These transactions involve a number of detailed steps (and the exact implementation can be found [here](https://github.com/UMAprotocol/protocol/blob/master/packages/scripts/src/upgrade-tests/voting2/1_Propose.ts)) and are briefly mentioned below: - -1. Changing the minter permissions on the UMA token -2. Adding the new governor as the owner of the voting token -3. Transferring UMA tokens held by old governor to the new governor -4. Transferring ownership of the finder to the [VotingUpgraderV2.sol](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/umip-helpers/VotingUpgraderV2.sol). This contract is used in a number of subsequent steps to ensure that the upgrade process is atomic. -5. Transfer ownership of existing voting to voting upgrader -6. Temporarily add the Governor as a contract creator -7. Register the ProposerV2 as a verified contract -8. Register the GovernorV2 as a verified contract -9. Transfer ownership of all remaining ownable contracts to the voting upgrader -10. Transfer all multirole ownership to the voting upgrader -11. Reset governance ownership to the voting upgrader for both the old and new governor -12. Execute upgrade through the voting upgrader. This is deployed [here](https://etherscan.io/address/0x13852D4AF390d8C3404c0577fd8B8E43389A290b). - -When executed, these transaction have the effect of moving all internal ownership to the voting upgrader contract and using this to upgrade the UMA DVM system atomically. Please see the linked upgrade scripts that outline the upgrade process in detail. The prior DVM (Voting) will no longer be used once it has been migrated, although unclaimed rewards from the previous contract can still be claimed using the new DVM 2.0. The migration will not not involve any interruption of the functionality of contracts using the DVM (OOv2, OO, etc.), as they will continue to function with DVM 2.0 after migration. - -Note that the upgrade transaction that calls into the `votingUpgraderV2` contract also contains a permissioned function `canRun` that blocks all accounts other than a known UMA account from executing this upgrade. This was done to ensure that that we can delay the execution of the upgrade in the event other price requests come in. - -## Security considerations - -The upgraded DVM contracts listed above have been audited by Open Zeppelin in two separate audits ([report1](https://blog.openzeppelin.com/uma-dvm-2-0-audit/), [report2](https://blog.openzeppelin.com/uma-dvm-2-0-incremental-audit/),[report3]()).

The UMIP-176 proposes a new way of handling the SHERLOCK_CLAIM price identifier that is aligned with the current implementation of the Sherlock Claim Manager. - -Sherlock is a DeFi audit marketplace and smart contract coverage protocol built on Ethereum. It provides audits by top security experts and offers optional coverage for audited contracts. In the claim lifecycle, Sherlock utilizes UMA's Optimistic Oracle and Data Verification Mechanism (DVM) for escalated claim resolution. - -In the event of a potential exploit, Sherlock’s security team will work with the protocol to determine the nature of a hack. If the protocol believes they experienced an exploit that should be covered by Sherlock, the protocol will submit the block range of the exploit and the amount to be reimbursed by Sherlock. Next, Sherlock’s claims committee will work to evaluate the nature of the potential exploit and then map the exploit to the coverage terms agreed to with that protocol. The committee will then decide whether to pay out the claim. If the committee decides not to pay out the claim, the protocol has the option to stake a minimum dollar amount ($50k for example) and escalate the claim to the UMA Data Verification Mechanism. The UMA tokenholders would then use information provided by the protocol, the claims committee, and importantly, security expert not associated with Sherlock in an unbiased way, to decide whether the claim should be paid out or not. - -Sherlock documentation can be found [here](https://docs.sherlock.xyz/). - -## Ancillary Data Specifications - -``` -Metric:Sherlock exploit claim arbitration, -Protocol:, -ChainId:, -Value:, -StartBlock:, -Resources:, -CoverageAgreement: -``` - -Example: - -``` -Metric:Sherlock exploit claim arbitration, -Protocol:UMA Protocol, -ChainId:1, -Value:1000000, -StartBlock:13207345, -CoverageAgreement:Link to protocol specific coverage agreement with Sherlock -``` - -## Rationale and usage - -The framing of the price identifier puts the responsibility on the protocol to specify the correct information in the ancillary data as described in Ancillary Data Specifications. If any of the information is not accurate, a payout will not occur. This is mitigated by the idea that a protocol will get up to 3 chances to correctly input the data in order to successfully trigger a payout. - -Because the potential request space is broad, it is possible that voters will not be able to arrive at a definitive result. In this case, the default return value should be `deny` (or `0`), which likely will also result in no payout from Sherlock to the claimer. This places the onus on the protocol to provide clear evidence that an exploit occurred. - -It is low risk for UMA voters to return a value of `0` if there is insufficient evidence to prove the claim with accuracy, as it is likely that this will result in a resubmission of the price request by the claiming protocol once they have have accumulated more concrete evidence of their claim. If a claim is paid out in error, there is little recourse for Sherlock at that point, so it seems reasonable that a protocol should have to prove that a payout occurred and that the default should be to `deny`, meaning a payout is not enacted. - -## Implementation - -1. Voters should decode the ancillary data and identify the protocol, chain, start block, dollar value of claim in question and any additional resources provided. -2. Because the protocol making the claim will likely be the party constructing the ancillary data and submitting a price request, voters should heavily rely on checking external resources for additional context. The Sherlock Coverage Terms Agreement should always be referenced. Additionally the Protocol's original claim as well as the Sherlock Claims Committee's original claims decision will likely always be published and should be referenced. Sherlock's Coverage Agreement details the exact types of exploits that Sherlock covers, and these should be the only exploits that are considered in arbitration. More information is provided in the `Additional Resources` section below. -3. Voters should return the USD `Value` within ancillary data converted to USDC decimals (the decimal USD value multiplied by 10e6) an thus `approve` the claim if they determine that: - 1. There was an exploit for the `Protocol` specified. - 2. The exploit type is covered by Sherlock's Coverage Agreement. - 3. The exploit happened as part of the `StartBlock` specified in ancillary data. - 4. The total USD value lost in the exploit is greater than or equal to the USD `Value` within ancillary data. -4. If voters cannot confidently assess one of the criterion above, they should return a value of `0` to `deny` the claim. - -## Additional Resources - -While the coverage agreement document between Sherlock and the protocol in question will serve as the canonical guideline as to whether an exploit falls under coverage or not, it is non-trivial to determine whether an exploit occurred, and how that exploit maps to the coverage agreement. - -Outside of the coverage agreement, UMA tokenholders should rely on 3 sources of information when making their decision: - -1.

The interpretation of the exploit and coverage agreement by the protocol in question. -3. Most important, the interpretation of the exploit and coverage agreement by third party security experts. - -While information in 1) and 2) should be readily available (both parties will be motivated to explain their interpretation), we can reasonably expect 3) to be readily available as well based on historical public interest in protocol exploits and past articles produced. - -Sources of 3) could be [rekt.news](https://twitter.com/RektHQ), [Mudit Gupta](https://twitter.com/Mudit__Gupta), [Kelvin Fichter](https://twitter.com/kelvinfichter), [Igor Igamberdiev](https://twitter.com/FrankResearcher), as well as audit firms such as [PeckShield](https://twitter.com/peckshield) as long as the parties don’t have material connection to either Sherlock or the protocol in question. - -## Implementation & Technical Specification - -This UMIP proposes a governance transaction that perform the following actions atomically: - -- Remove the `SHERLOCK_CLAIM` identifier by calling `removeSupportedIdentifier(bytes32 identifier)` method of IdentifierWhitelist contract found [here](https://etherscan.io/address/0xcF649d9Da4D1362C4DAEa67573430Bd6f945e570) with the hexadecimal representation of the `SHERLOCK_CLAIM` identifier as a parameter. -- Add again the `SHERLOCK_CLAIM` identifier by calling `addSupportedIdentifier(bytes32 identifier)` method of IdentifierWhitelist contract found [here](https://etherscan.io/address/0xcF649d9Da4D1362C4DAEa67573430Bd6f945e570) with the hexadecimal representation of the `SHERLOCK_CLAIM` identifier as a parameter. - -## Security Considerations - -It should be noted that this price identifier is objectively complex and broad and will likely require a large amount of active participation from UMA voters to correctly analyze and resolve these requests. UMA voters should not be expected to be security experts, and therefore do not accept any liability from potential claims from either the claiming protocol or Sherlock. UMA voters should only be expected to act as an impartial jury; their responsibility is to synthesize information from ancillary data, `Additional Resources`, Sherlock's coverage terms and ad hoc information provided by Sherlock and the claiming protocol during arbitration, but not to perform complete security analysis themselves. - -There are also several mitigating processes built into the Sherlock system as well as the UMA voting system. As noted previously, claiming protocols will have up to 3 total chances to submit claims and go to a DVM vote. This should allow for comprehensive information gathering and analysis, and will allow UMA voters to default to a `0` return value unless clear supporting evidence is provided either to support or contradict a claim. - -The DVM voting system also allows for a multi-day discussion and information gathering process. Because of this reason, it seems acceptable that the potential price request space for this identifier is broad and potentially subjective. Both the claiming protocol, as well as Sherlock's security committee will have the opportunity to provide supporting evidence and advocate for their case. It is recommended that both parties be active in UMA's #voting [Discord channel](https://discord.gg/YE4h2YAb), as this is where most UMA voting discussion occurs. diff --git a/research/uma/umips/UMIPs/umip-177.md b/research/uma/umips/UMIPs/umip-177.md deleted file mode 100644 index 3e5bf53c..00000000 --- a/research/uma/umips/UMIPs/umip-177.md +++ /dev/null @@ -1,154 +0,0 @@ -## Headers - -| UMIP 177 | | -| --- | --- | -| UMIP Title | ROPU_ETHx | -| Authors | Gabriel Astieres | -| Status | Draft | -| Created | 03/04/23 | -| Discourse Link | | - -# Summary - -The DVM should support price requests for ROPU_ETHx. ROPU_ETHx reflects violations of the MEV-policy committed by validators of the ETHx staking protocol.

The list should be empty if no violations were found. - -The report covers a specific time period, start and end designated by an epoch number of the beacon chain. Only events that occurred during this time period are considered when evaluating the report.

All those 4 elements should be reflecting the reality of what happened on chain to be considered correct. - -It's important to note that a validator's status regarding the ETHx MEV policy may change over time. Therefore, proposed and missed violations should be evaluated against the validator's state at the time of the suspected violation. - -# Implementation - -In order for voters to determine the validity of the claim, they should refer to the following contracts: - -- The Rated smart contract, which is the original creator of the claim. -- The ETHx config, which lists all the addresses of the ETHx protocol. Information needed to get validators’ state will be held in `PermissionlessNodeRegistry` and `PermissionedNodeRegistry`. On Ethereum mainnet, this contract is deployed at `0x4ABEF2263d5A5ED582FC9A9789a41D85b68d69DB`. - -**The steps to evaluate a report are the following:** - -1. Voters should decode the ancillary data to get the corresponding `ID` of the report to examine. -2. Voters should read the storage of the Rated smart contract in the `reports` mapping to access the corresponding report. -3. Voters should get from the report what time window it covers. Using `fromEpoch` and `toEpoch` marking when it begins and ends using Beacon Chain epoch numbers. -4. Voters should access the list of `Violations` contained in the report. If the list is empty, this means that no violations were found for the given period. -5. For each of the `Violation` contained, voters should attest to its accuracy. -To do so, voters should search for validators from the ETHx protocol who proposed blocks during the relevant time period. If these validators received MEV or priority fees payments, they should have received them at predetermined addresses based on whether they belong to the `Permission-less` or `Permissioned` pool and whether they opted-in to the socialisation of MEV rewards. A table of acceptable payment addresses for each scenario is provided below. -When a block is coming from an MEV-relay, the `newFeeRecipientAddress` should be the end of block transfer that the builder used to pay the proposer. However, in some instances, builders pay the proposer through an internal transaction. In such cases, when the appropriate ETHx address is paid, this does not constitute a violation. More on this new form of payment in this [Rated post](https://feedback.rated.network/p/updating-ethereum-el-mev-boost-rewards-attribution-methodology-to-capture). -6. Finally, if voters identify any violations that occurred during the period and were not reported, the report should be considered incomplete, and the claim should be marked as false. - -| Penalty type | Pool type | Socializing pool opt-in | Expected fee recipient address | -| --- | --- | --- | --- | -| 1 | Permission-less | No | Permission-less socialising pool OR Operator’s EL reward vault address | -| 2 | Permission-less | Yes | Permission-less socialising pool | -| 3 | Permission-less | Opted-out in the last 3 epochs* | Permission-less socialising pool | -| 4 | Permission-less | Opted-out more than 3 epochs ago* | Permission-less socialising pool OR Operator’s EL reward vault address | -| 5 | Permission-less | Opted-in in the last 3 epochs* | Permission-less socialising pool OR Operator’s EL reward vault address | -| 6 | Permission-less | Opted-in more than 3 epochs ago* | Permission-less socialising Pool | -| 7 | Permissioned | n/a | Permissioned socialising Pool | - - -💡 \* 3 epochs exclusive between the reported violation and opt-in/out action of the operator. - -💡 The fee recipient addresses on the ROPU report should be different than those on the table above, for their respective penalty types. - -### An example: - -This transaction is a new report brought by Rated on chain: [transaction](https://goerli.etherscan.io/tx/0xd767d6b92354273068c4078028c86f37f0e89754f7f56fe590b2edd42fac5a5f) - -The new report creates a claim on the Optimistic Oracle v3. - -![umip-177_a](./images/umip-177_a.png) - -This claim is linked to the report number 5 on the Rated Oracle. The voters should retrieve the content of this report by reading the **`reports`** mapping in the Rated Oracle. - -![umip-177_b](./images/umip-177_b.png) - -The voters should also look for the violations contained in the said report by calling the getter **`getViolationsInReport`:** - -![umip-177_c](./images/umip-177_c.png) - -Now that those value were retrieved, the voters have all the elements to determine the validity of the report. As seen above, this report covers the period of time between epoch `176809` and `176829` of the beacon chain (prater in this example). - -In this example, the report contains 1 violation. It is said to be perpetrated on epoch `176819`. Indeed, this block was proposed by a validator from the ETHx set.

Voters have therefore to check that either the transaction at the end of the block or the fee recipient is one of acceptable addresses as defined in the previous table. For this slot, the recipient of the transaction at the end of the block is `0x6da4c7af13ecb85c5283b0b78fbd3c204efb2c0c` which is the ETHx permissionless socializing pool. Therefore, this validator did not violate the ETHx policy, and this does not constitue a valid violation, making this example report incorrect. - -# Security Considerations - -When resolving a dispute, the process in the DVM shall ensure two things at once: - -- (i) That every violations presented in the associated report are correct. -- (ii) That the report is complete and that it includes every violation in the time frame concerned. - -Also, the Rated Smart Contract, expects the disputed reports to settle in less than 4 days, considering a new vote every 2 days and 2 days long process.

ABT inherits directly from a standard WETH9 implementation, and wraps the transferFrom() function to apply custom transfer logic. This permits Across to realise a permissioned set of HubPool proposers, thereby reducing the attack surface of Across. All other ERC20 functions are completely standard. - -## Motivation - -Across relies on an Optimistic Asserter proposal pattern in order to verify that any proposed allocation of HubPool funds is valid and correct. Across proposers submit a proof as part of their proposal, which can be permissionally verified and optionally disputed by any observer of the system. Proposals that survive a 2 hour challenge window are subsequently able to be executed, thereby resulting in the movement of funds. - -As with disputing, it is currently permissionless to propose a root bundle proposal in Across. This unfortunately provides an opportunity for malicious third-parties to submit invalid proposals in order to extract funds from the system. This marginal risk dictates the need for a lengthy challenge window on proposals in order to ensure that any such proposals are detected and disputed. This thereby reduces the number of proposals that can be made and ultimately limits the frequency at which Across HubPool funds can be allocated to bridging activities, such as refunding relayers for user deposits that they have filled. - -The Across Bond Token has been designed specifically to enhance the security of Across by limiting the set of possible Across proposers, whilst still allowing any independent observer to dispute an invalid proposal. By ensuring that proposals only originate from pre-approved actors, Across will have reduced its attack surface and will therefore be able to reduce its 2 hour challenge window. This will allow Across to scale further by reducing the time that relayers must wait for refunds, thereby improving their capital efficiency, and will ultimately deliver a better experience for the users of Across. - -## Technical Specification - -The following changes are proposed: - -- The ABT address [0xee1DC6BCF1Ee967a350e9aC6CaaAA236109002ea](https://etherscan.io/address/0xee1DC6BCF1Ee967a350e9aC6CaaAA236109002ea) shall be added to the collateral currency list introduced by UMIP-8. -- A final fee of 0.135 shall be configured for ABT in the relevant Store contract (nominally [0x54f44eA3D2e7aA0ac089c4d8F7C93C27844057BF](https://etherscan.io/address/0x54f44eA3D2e7aA0ac089c4d8F7C93C27844057BF). - -## Rationale - -The final fee of 0.135 matches the existing WETH final fee. ABT can be minted and redeemed at a rate of 1:1 against Ether. - -## Implementation -ABT implements a simple mechanism that restricts the set of possible proposers, whilst still allowing for permissionless disputes. It achieves this be overriding the WETH9 transferFrom() function in order to implement custom transfer logic, such that it prevents any non-approved address from transferring any amount of ABT to the Across v2 HubPool contract if they are recorded as the current proposer. This effectively prohibits Across HubPool proposals by any non-approved addresses. All other ERC20 functionality is inherited directly from a local WETH9 implementation. - -The set of permitted proposers will be configurable and the can be managed by the ABT contract owner. The fact that proposers must be known to Across in advance significantly reduces the probability of an incorrect proposal being submitted, and thereby provides opportunity for the proposal challenge window to be reduced. - -Migration to the ABT token for use as a bond collateral token will successfully retain the existing security properties of Across whilst dramatically reducing the attack surface area that malicious proposers might seek to exploit. - -## Security considerations - -This collateral type has been developed in-house by the Across team to address a specific need with respect to the proposal lifecycle. Its capabilities are limited to basic ERC20 functions, and it inherits most of its functionality from the WETH9 contract that has previously been used within the UMA ecosystem. The token has been [audited by OpenZeppelin](https://blog.openzeppelin.com/uma-across-v2-audit), with only minor typographical errors found. The ABT contract is not upgradeable, and no marginal risks to the UMA ecosystem have been identified. - -Contract deployers considering using this collateral in an UMA contract should refer to the [guidelines on collateral type usage](https://docs.umaproject.org/uma-tokenholders/guidence-on-collateral-currency-addition) to ensure appropriate use. diff --git a/research/uma/umips/UMIPs/umip-179.md b/research/uma/umips/UMIPs/umip-179.md deleted file mode 100644 index 4bd6e3ba..00000000 --- a/research/uma/umips/UMIPs/umip-179.md +++ /dev/null @@ -1,826 +0,0 @@ -# Headers -- UMIP 179 -- Title: Update the **ACROSS-V2** price identifier to support Across v3 -- Author paul@across.to -- Status: Last Call -- Created: 2023-02-17 -- Discourse Link: N/A - -# Summary -This UMIP defines the updated protocol specification for Across V3.

SVM numbers are encoded as little-endian, so the byte order is reversed compared to EVM. | -| uint256 | [u8; 32] | Used for numbers that cannot possibly fit into 64 bits. This is used for deposit IDs and foreign token amounts. Here the byte order is big-endian matching the EVM representation. | -| uint32 | u32 | Used for numbers that fit into 32 bits. SVM numbers are encoded as little-endian, so the byte order is reversed compared to EVM. | -| bytes | Vec<u8> | Used for arbitrary byte arrays. In SVM this is encoded as the first 4 bytes holding the length of the array (little-endian encoded) followed by the array byte items. | - -Also note that SVM uses snake case for struct field names compared to camel case in EVM. - -### V3RelayData -The `V3RelayData` type underpins the transfer of funds in or out of a SpokePool instance. `V3RelayData` is defined as follows: -| Name | Type | Description | -| :--- |:---- | :---------- | -| depositor | bytes32 | The address that made the deposit on the origin chain. | -| recipient | bytes32 | The recipient address on the destination chain. | -| exclusiveRelayer | bytes32 | The optional exclusive relayer who can fill the deposit before the exclusivity deadline. | -| inputToken | bytes32 | The token that is deposited on the origin chain by the depositor. | -| outputToken | bytes32 | The token that is received on the destination chain by the recipient. | -| inputAmount | uint256 | The amount of inputToken that is deposited by the depositor. | -| outputAmount | uint256 | The amount of outputToken that is received by the recipient. | -| originChainId | uint256 | The chain ID of the origin SpokePool. | -| depositId | uint256 | The ID identifying a deposit on the origin chain. | -| fillDeadline | uint32 | The Unix timestamp on the destination chain after which the deposit can no longer be filled. | -| exclusivityDeadline | uint32 | The optional Unix timestamp on the destination chain after which any relayer can fill the deposit. | -| message | bytes | Optional data that is forwarded to the recipient as part of a relay. | - -#### Note -- `V3RelayData` specifies `bytes32` representation for addresses (`depositor`, `recipient`, ...) in order to interface with non-EVM chains. The EVM address supplied shall be promoted to type `bytes32` with the upper 12 bytes zeroed. - -#### SVM support - -`RelayData` in SVM represents the same data as `V3RelayData` in EVM: - -| Name | Type | -| :--- |:---- | -| depositor | Pubkey | -| recipient | Pubkey | -| exclusive_relayer | Pubkey | -| input_token | Pubkey | -| output_token | Pubkey | -| input_amount | u64 / [u8; 32] | -| output_amount | u64 / [u8; 32] | -| origin_chain_id | u64 | -| deposit_id | [u8; 32] | -| fill_deadline | u32 | -| exclusivity_deadline | u32 | -| message | Vec<u8> | - -`input_amount` and `output_amount` types depend on their use case: -- little-endian encoded `u64` for native token amounts (`input_amount` for deposits and `output_amount` for fills) -- big-endian encoded `[u8; 32]` for foreign token amounts (`output_amount` for deposits and `input_amount` for fills) - -### V3RelayDataLegacy -The `V3RelayDataLegacy` type is supported for backwards compatibility, but is slated for deprecation. `V3RelayDataLegacy` has the following delta to the `V3RelayData` type: -| Name | Type | -| :--- |:---- | -| depositor | address | -| recipient | address | -| exclusiveRelayer | address | -| inputToken | address | -| outputToken | address | -| depositId | uint32 | - -### FillStatus -A mapping of `RelayData` -> `FillStatus` is stored within each SpokePool instance. This mapping can be queried with the hashed `V3RelayData` for a deposit, allowing the status for the corresponding fill to be queried. - -| Name | Value | Description | -| :--- | :---- | :---------- | -| Unfilled | 0 | The SpokePool has no known state for the corresponding `V3RelayData` hash. | -| RequestedSlowFill | 1 | A SlowFill request has been made for this V3RelayData hash. A corresponding `RequestedV3SlowFill` event has been previously emitted. | -| Filled | 2 | A fill (fast or slow) for this `V3RelayData` hash has been completed. | - -#### SVM support - -`RelayData` and its destination `chain_id` are mapped to a `FillStatus` via `FillStatusAccount` that is a PDA (Program Derived Address) derived from `svm_spoke` program ID using the string `fills` and 32 byte `relay_hash` as the seeds. `relay_hash` is computed using `solana_program::keccak` over the `RelayData` and `destination_chain_id` as described in SVM support of [Computing RelayData Hashes](#computing-relaydata-hashes). - -`FillStatusAccount` stores following fields: - -| Name | Type | Description | -| :--- |:---- | :---------- | -| status | FillStatus | The status of the mapped fill, see below. | -| relayer | Pubkey | Address of the relayer that made the fill to control who can close this PDA. | -| fill_deadline | u32 | Fill deadline to control when this PDA can be safely closed. | - -`FillStatus` is an enum with the same values as in EVM, but one should consider the fact that on SVM it is only useful for internal program logic as the `FillStatusAccount` can be closed by the relayer after the fill deadline has passed, so the status is not persisted onchain indefinitely. In order to reconstruct the status of a fill, one should look for `FilledRelay` and `RequestedSlowFill` events in all transactions where the `FillStatusAccount` was involved (`getSignaturesForAddress` RPC method can be useful). If there are no such events, then the fill can be considered `Unfilled`. If the `FilledRelay` is found as the last event, then the fill is considered `Filled`. If there is only a `RequestedSlowFill` event, then the fill is considered `RequestedSlowFill`. - -### FillType -A FillType instance is emitted with each `FilledV3Relay` event (see below). - -| Name | Value | Description | -| :--- | :---- | :---------- | -| FastFill | 0 | The relay was completed by a relayer as a fast fill. | -| ReplacedSlowFill | 1 | The relay was initially requested to be completed via slow fill, but was subsequently fast-filled by a relayer. | -| SlowFill | 2 | The relay was completed via slow fill. | - -#### SVM support - -`FillType` enum is emitted with each `FilledRelay` event on SVM with the same interpretation as when emitted with `FilledV3Relay` events on EVM. - -### V3RelayExecutionEventInfo -A V3RelayExecutionEventInfo instance is emitted with each `FilledV3Relay` event (see below). - -| Name | Type | Description | -| :--- |:---- | :---------- | -| updatedRecipient | bytes32 | The recipient of the funds being transferred. This may be the `recipient` identified in the original deposit, or an updated `recipient` following a `RequestedSpeedUpV3Deposit` event. | -| updatedMessageHash | bytes32 | The hash of the updated message sent to the recipient. This is computed as `keccak256(message)` where `message` is the `message` bytes in the `RelayData`.

This always matches the original recipient as there is no speedup functionality in the `svm_spoke` program. | -| updated_message_hash | [u8; 32] | The hash of the message sent to the recipient. This is computed as `solana_program::keccak::hash(message)` where `message` is the `message` bytes in the `RelayData`. If the `message` field is empty, this will be set to `[0u8; 32]`. | -| updated_output_amount | u64 | The amount of the tokens being transferred. This always matches the original amount as there is no speedup functionality in the `svm_spoke` program. | -| fill_type | FillType | Type of fill completed (see `FillType` above). | - -### V3SlowFill -A `V3SlowFill` instance is used to calculate slow relay root when proposing and verifying the root bundle.

This is used only when proposing and verifying the root bundle while on execution SpokePool overrides it with its actual chain ID. | -| updatedOutputAmount | uint256 | The amount sent to `recipient` as part of a SlowFill. This should typically be equal to or greater than the `V3FundsDeposited` `outputAmount`. | - -#### Notes -The `updatedRecipient` field is normally set to the `recipient` from the corresponding `V3FundsDeposited` event. In the event that the relayer completes the fill with an accompanying `RequestedSpeedUpV3Deposit` event, `updatedRecipient` will be set to the address approved by the update. - -#### SVM support - -A `SlowFill` instance is used to calculate slow relay root when proposing and verifying the root bundle.

In addition, the encoded `SlowFillLeaf` must be prefixed with 64 bytes of zeroes to protect against any possibility of an EVM leaf being used on SVM or vice versa. - -## Definitions - -### Deposits -A `Deposit` is defined as an instance of either of the following events: -- `FundsDeposited`. -- `V3FundsDeposited`. - -#### SVM support - -On SVM chains a `Deposit` is defined as an instance of `FundsDeposited` event. - -### Fills -A `Fill` is defined as an instance of either of the following events: -- `FilledRelay`. -- `FilledV3Relay`. - -#### SVM support - -On SVM chains a `Fill` is defined as an instance of `FilledRelay` event. - -### Slow Fill Requests -A `Slow Fill` is defined as an instance of either of the following events: -- `RequestedSlowFill`. -- `RequestedV3SlowFill`. - -#### SVM support - -On SVM chains a `Slow Fill` is defined as an instance of `RequestedSlowFill` event. - -### RelayData -`RelayData` is defined as an instance of etiher of the following data types: -- `V3RelayData`. -- `V3RelayDataLegacy`. - -#### SVM support - -On SVM chains, `RelayData` is defined as an instance of the `RelayData` data type as described in the supported SVM [Data Types](#data-types) section above. - -### Bundle Block Range -The `Bundle Block Range` is the pair of start and end blocks for a given proposal. See [Identifying Bundle Block Ranges](#identifying-bundle-block-ranges) for guidance on identifying the `Bundle Block Range`. - -#### SVM support - -On SVM chains the `Bundle Block Range` is the pair of start and end slots. - -### Fill Status -A `Deposit` is considered to be `Filled` on the destination chain when the destination `SpokePool` `FillStatus` mapping shows state `Filled` for the `Deposit` `RelayData` hash. - -#### SVM support - -A `Deposit` is considered to be `Filled` on the destination SVM chain when its `FillStatus` is resolved to `Filled` using `FillStatusAccount` as described in the supported SVM [Data Types](#data-types) section above. - -## Method -### Identifying SpokePool Contracts -The current SpokePool address for a specific chain is available by querying `HubPool.crossChainContracts()`. The chainId must be specified in the query. In case of SpokePool migations, historical SpokePool addresses can be identified by scraping HubPool `CrossChainContractsSet` events. - -#### SVM support - -The procedure for identifying the current SpokePool program for a specific SVM chain is as follows: - -1. Query the `HubPool` contract for the `crossChainContracts()` mapping using the `chainId` of the SVM chain to get the address of chain specific `adapter` contract. -2. Query the `adapter` contract for the `SOLANA_SPOKE_POOL_BYTES32()` method to get the `bytes32` representation of SVM program ID. -3. Convert the `bytes32` representation to a Base58 encoded `Pubkey` of SVM SpokePool program. - -In case of SpokePool migrations, historical SpokePool addresses can be identified by scraping HubPool `CrossChainContractsSet` events and querying the previous `adapter` contract. - -### Identifying "Lite" deployments -We consider a deposit to "originate" or be "destined for" a "Lite chain" if the `LITE_CHAIN_ID_INDICES` value in the AcrossConfigStore includes the deposit's origin chain or destination chain respectively as of the deposit's `quoteTimestamp` field. These chains impose constraints on relayer repayments and slow fills. - -### Resolving SpokePool tokens to their HubPool equivalent -For the purpose of identifying the equivalent HubPool token given a SpokePool token, the following shall be followed: -1. Find the latest `SetRebalanceRoute` event with a block timestamp at or before the relevant HubPool block number, where the relevant SpokePool chain ID and token address match the `SetRebalanceRoute` `destinationChainId` and `destinationToken` fields. - - In the case of a `Deposit` event, the relevant HubPool block number is identified by resolving the `quoteTimestamp` to a HubPool block number. -3. From the resulting `SetRebalanceRoute` event, select the associated `l1Token` field. -4. Search the `SetPoolRebalanceRoute` events for the same `l1Token` and `destinationChainId` at or before the applicable HubPool block number. -5. Using the `l1Token` value found in step 2, search for the latest `SetRebalanceRoute` event at or before the applicable HubPool block number where `l1Token` and `destinationChainId` that match the extracted `l1Token` and SpokePool chain ID. If a match is found, the addresses match and are considered cross-chain equivalents. - -#### SVM support - -Convert Base58 encoded `Pubkey` of SVM chain SpokePool token to its `bytes32` representation and convert to EVM address by trimming off the first 12 bytes. Use this EVM token address representation as the `destinationToken` following the instructions in the generic [Resolving SpokePool tokens to their HubPool equivalent](#resolving-spokepool-tokens-to-their-hubpool-equivalent) section above. The integrators should be aware of this SVM address trimming and bear the responsibility to use the correct SVM token address that would correctly resolve to the `l1Token` address. - -### Identifying Bundle Block Ranges -In addition to the description [UMIP-157](https://github.com/UMAprotocol/UMIPs/blob/pxrl/umip179/UMIPs/umip-157.md#determining-block-range-for-root-bundle-proposal): -- Proposers may opt to reduce the size of the proposal block range for each chain in the event that RPC provider data inconsistencies are detected, and -- A "soft pause" of a chain is permitted in the event that the proposer cannot safely increment the bundle block range, or has no events to propose beyond the previous bundle block range. In this case, the proposer may repeat the procedure for - DISABLED_CHAINS by proposing from and to the previous bundle end block. - -#### SVM support - -Bundle block ranges for SVM chains are identified by their slot numbers. For the end slot, only such slot should be used that has a corresponding block produced for it. - -### Reconstructing FilledRelay messages -The `FilledRelay` event emits the `messsageHash` field. This field is set as follows: -- When the `RelayData` `message` field is empty (`0x`): `bytes32(0)`, OR -- When the `RelayData` `message` field is non-empty (`0x...`): `keccak256(message)`. - -#### SVM support - -The `FilledRelay` event on SVM emits the `message_hash` field. This field is set as follows: -- When the `RelayData` `message` field is empty: `[0u8; 32]`, OR -- When the `RelayData` `message` field is non-empty: `solana_program::keccak::hash(message)`. - -### Computing RelayData Hashes -A `RelayData` hash is computed as the `keccak256` hash over the ABI-encoded representation of the arguments `relayData`, `destinationChainId`, where: -- `relayData` is of type `V3RelayData` or `V3RelayDataLegacy`. -- `destinationChainId` is of type `uint256`. - -- When the `FilledRelay` event data omits the `message` field, the `message` field shall be populated according to the procedure specified in [Reconstructing FilledRelay messages](#resonstructing-filledrelay-messages). - -#### Note -- This method produces the identical hashes for `V3RelayData` and `V3RelayDataLegacy` for the same input data due to `address` promotion to `bytes32` prior to hashing. - -#### SVM support - -A `RelayData` hash on SVM is computed as the `solana_program::keccak` hash over the Borsh serialized representation of concatenated `relay_data` and `destination_chain_id`, where: -- `relay_data` is derived from `RelayData` replacing the `message` field (type Vec<u8>) with its `message_hash` (type [u8; 32]) as described in the SVM support for [Reconstructing FilledRelay messages](#reconstructing-filledrelay-messages) section above, and -- `destination_chain_id` is little-endian encoded `u64` representation of destination chain ID. - -### Computing Relayer Repayments & Depositor Refunds -For the purpose of computing relayer repayments, the following procedures are completed: -- Validating Fills -- Validating Pre-Fills -- Finding Expired Deposits -- Finding Unfillable Deposits - -#### Note -- Depositor refunds are issued via the Relayer Repayment workflow. - -### Validating Fills -Each of the `Fills` emitted within the `Bundle Block Range` on a destination SpokePool shall be considered valid by verifying that: -1. The `Fill` event `FillType` field is not set to `SlowFill`, AND -2. The component `RelayData` maps exactly to one or more corresponding `Deposit` events emitted on the relevant `originChainId`, AND -3. The corresponding `Deposit` event occurred within or before the `Bundle Block Range` on the origin chain SpokePool. - -#### Note -- If the `Deposit` event specifies `outputToken` `bytes32(0)` (i.e. the Zero Address), the equivalent SpokePool token on the destination chain shall be substituted in. For the purpose of determining `RelayData` equivalency, the updated/substituted `outputToken` shall be used in place of the Zero Address. If there is no equivalent SpokePool token on the destination chain at the `Deposit` `quoteTimestamp`, then any fill for this deposit will not be repaid regardless of whether it is fillable on the destination. -- `RelayData` equality can be determined by comparing the keccak256 hashes of two `RelayData` objects. -- Fills of type `SlowFill` are valid, but are not relevant for computing relayer repayments. - -#### SVM support - -When validating fills between EVM and SVM chains, one should consider the differences in the field naming, types and encodings used on SVM chains as described in the supported SVM [Data Types](#data-types) section above. In order to compare the `RelayData` one should be able to safely convert between EVM and SVM representations as in practice all amounts should fit into 64 bits. - -### Validating Pre-fills -For each of the `Deposits` emitted within the `Bundle Block Range` where no corresponding `Fill` is identified on the destination chain within the `Bundle Block Range`, identify the valid `Fill` according to the following criteria: -1. Verify that the destination chain `FillStatus` for the `Deposit` `RelayData` is `Filled` as at the destination chain end block number for the proposal. -2. Resolve the corresponding `Fill` on the destination chain. -3. Verify that the `FillType` is `FastFill` or `ReplacedSlowFill` AND that the `Fill` occurred prior to the current the `Bundle Block Range` on the destination chain SpokePool. - -#### Note -- No specific method is prescribed for resolving the `Fill` on the destination chain. An `eth_getLogs` request can facilitate this, and if required, the `Bundle Block Range` could be narrowed by a binary search over the `FillStatus` field. This is left as an implementation decision. - -#### SVM support - -In order to resolve the `Fill` on the destination SVM chain, one can inspect transactions where the `FillStatusAccount` PDA was involved (using `getSignaturesForAddress` RPC method) as described on the SVM supported [Data Types](#data-types) section above and looking for the emitted `FilledRelay` event. - -### Finding Expired Deposits -For the purpose of computing depositor refunds, each `Deposit` shall be considered expired by verifying that: -1. The `fillDeadline` timestamp elapsed within the `Bundle Block Range` on the destination SpokePool (i.e. the `fillDeadline` expired between the `block.timestamp` of the destination chain's bundle start and end block), -2. The `FillStatus` on the destination SpokePool is set to `Unfilled` or `SlowFillRequested` as at the end of the `Bundle Block Range`. - -#### Note -- Expired deposits shall be refunded to the `depositor` address on the origin SpokePool. -- Depositor refunds are to be issued as part of the relayer refund procedure. -- The `fillDeadline` timestamp shall be resolved to a block number on the destination chain in order to determine inclusion within the `Bundle Block Range`. - -#### SVM support - -When evaluating if the `fillDeadline` / `fill_deadline` timestamp elapsed within the `Bundle Block Range` on the SVM destination SpokePool, one can use `getBlock` RPC method for the destination chain's bundle start and end slot and use the `blockTime` field to compare against the `fillDeadline` / `fill_deadline` timestamp. End slot must always have a corresponding block produced, but if there is none for the start block, one should get the timestamp from the last produced block before such empty start slot. - -### Finding Unfillable Deposits -For the purpose of computing depositor refunds, each duplicate `Deposit` shall be considered unfillable by verifying that: -1. The `Deposit` is identical with another `Deposit`. -2. The destination chain `FillStatus` for the `Deposit` is `Filled`. -3. The destination chain `Fill` `FillType` was `SlowFill`. -4. The destination chain `Fill` occurred within the current `BundleBlockRange` or the `Deposit` occurred within the current `BundleBlockRange`. - -#### Note -- `Deposits` are considered identical when their `RelayData` matches. -- `Deposits` are considered duplicate when they are emitted after their initial identical instance. - -### Finding Slow Fill Requests -For the purpose of computing slow fills to be issued to recipients, each `Slow Fill Request` emitted within the `Bundle Block Range` on a destination SpokePool shall be considered valid by verifying that: -1. The `fillDeadline` is greater than `destinationChainId` bundle end block's `block.timestamp`, -2. The `Slow Fill Request` `RelayData` is matched by one or more corresponding `Deposit` events that occurred within or before the `Bundle Block Range` on the origin SpokePool, -3. The `inputToken` and `outputToken` addresses are equivalent at the earliest matching deposit's `quoteTimestamp`, -4. The destination SpokePool `FillStatus` mapping for the relevant `RelayData` hash is `SlowFillRequested` at the end of the `Bundle Block Range`, -5. The `originChainId` and `destinationChainId` are not Lite chains. - -#### Note -- A `Slow Fill Request` is made by supplying a complete copy of the relevant `RelayData` emitted by a `Deposit` event. -- The resulting set of validated `Slow Fill Requests` shall be included as SlowFills in the subsequent root bundle proposal. -- A `Slow Fill Request` may correspond to a `Deposit` from previous bundles. - -#### SVM support - -When evaluating if the `fillDeadline` / `fill_deadline` timestamp is greater than `destinationChainId` bundle end slot time, one can use `getBlock` RPC method for the destination chain's bundle end slot and use the `blockTime` field to compare against the `fillDeadline` / `fill_deadline` timestamp. - -### Finding Early Slow Fill Requests -When an early `Slow Fill Request` is implied, the `Slow Fill Request` shall be validated as follows: -1. The `fillDeadline` has not already elapsed relative to the `destinationChainId` bundle end block number, -2. The `inputToken` and `outputToken` addresses are equivalent at the earliest matching deposit's `quoteTimestamp`, -3. Neither the`originChainId` nor the `destinationChainId` is a `Lite` chain. - -#### Note -- An early `Slow Fill Request` is implied where a `Deposit` emitted within the current `Bundle Block Range` has a `FillStatus` of `SlowFillRequested` as at the end of the current `Bundle Block Range` on the destination chain, but where no `Slow Fill Request` is identified within the current `Bundle Block Range`. This may occur where the `Slow Fill Request` was submitted prior to the current bundle. - -### Computing LP Fees -Each valid `Fill` is subject to an LP fee. The procedure for computing LP fees is as defined in [UMIP-136 Add IS_RELAY_VALID as a supported price identifier](https://github.com/UMAprotocol/UMIPs/blob/7b1a046098d3e2583abd0372c5e9c6003b46ad92/UMIPs/umip-136.md), with the following amendments: -- The AcrossConfigStore contract shall be used to identify the correct rate model, instead of a `RateModelStore` contract. -- The `HubPool` `liquidityUtilizationCurrent()` and `liquidityUtilizationPostRelay()` functions shall be used instead of the `BridgePool` variant. -- The event `inputToken` shall be mapped from the SpokePool address to a HubPool `l1Token` address by following the matching procedure outlined above. -- The LP fee is computed between the `originChainId` specified by the `Deposit` and `repaymentChainId` specified by the relayer, where the `relayExecutionInfo.FillType != SlowFill` and the Fill `destinationChainId` otherwise. If the `originChainId` is equal to the `repaymentChainId` then the LP fee should be 0%. - -#### Note -- The LP fee is typically referenced as a multiplier of the `Deposit` `inputAmount`, named `realizedLpFeePct` elsewhere in this document. - -### Computing Bundle LP Fees -The bundle LP fee for a `Bundle Block Range` on a SpokePool and token pair shall be determined by summing the applicable LP fees for each of the following validated events: -- `FilledRelay`. -- `FilledV3Relay`. - -#### Note - -Each `FilledRelay` or `FilledV3Relay` can have multiple associated deposit events. In the event of multiple matching deposit events, there will be multiple LP fees paid per event in the case of a non slow fill. - -### Computing Relayer Repayments -For each validated matching `Deposit` event, the relayer repayment amount shall be computed as follows: -- `(inputAmount * (1 - realizedLpFeePct)) / 1e18`, where `realizedLpFeePct` is computed over the set of HubPool `l1Token`, `originChainId` and `repaymentChainId` at the HubPool block number corresponding to the relevant `Deposit` `quoteTimestamp`. -- The applicable rate model shall be sourced from the AcrossConfigStore contract for the relevant `l1Token`. -- For a given `Fill` that satisfies the requirements for relayer repayment, each matching `Deposit` generates a distinct repayment computed against its `quoteTimestamp`. - -The applied `repaymentToken` will be equal to the [equivalent](#resolving-spokepool-tokens-to-their-hubpool-equivalent) token as the `inputToken` on the `repaymentChainId`, where the applied `repaymentChainId` shall be determined as follows (all at the time of the relevant bundle's hub chain end block): -- When the `originChainId` is a `Lite chain`: `originChainId`, ELSE -- When no `PoolRebalanceRoute` exists for the `inputToken` on the `Fill` `originChainId`: `originChainId`, ELSE -- When no `PoolRebalanceRoute` exists for the `repaymentToken` on the `Fill` `repaymentChainId`: `originChainId`, ELSE -- The `repaymentChainId` as specified in the `Fill`. - -The applied `repayment address` shall be determined as follows: -- When the `Fill` `relayer` address is valid for the applied `repaymentChainId`: `relayer`, ELSE -- The `Fill` `msg.sender` address. In this case, change the applied `repaymentChainId` to the `destinationChainId` if a `PoolRebalanceRoute` exists for both the `outputToken` on the `destinationChainId` and the `inputToken` on the `originChainId` as at the bundle's hub chain end block - -If the applied `repayment address` is not valid for the applied `repaymentChainId`, the repayment shall be discarded from the relayer refund root but still considered when [computing running balances & net send amounts](#computing-running-balances--net-send-amounts). That way they could still be refunded manually by relaying a separate refund bundle via spoke pool admin function once the affected relayer provides a valid refund address on the applied `repaymentChainId` (precise mechanism is out of protocol scope, but that can be done by signing a message from the fill sender address). Examples of an invalid `relayer` address include: -- An SVM address on an EVM chain. -- An EVM address on an SVM chain. Even though in theory one might hold a corresponding private key, Across would not support refunding a relayer on a SVM chain to an address that has zeroes in its first 12 bytes. - -The rules above enforce that a `repaymentToken` for a successful relayer repayment is always equal to a token that is [equivalent](#resolving-spokepool-tokens-to-their-hubpool-equivalent) to the `inputToken` at the time of relevant bundle's hub chain end block. - -#### SVM support - -All the rules for computing relayer repayments as described in the generic [Computing Relayer Repayments](#computing-relayer-repayments) section above apply to SVM chains, except there is no `Fill` `msg.sender` address fallback logic when the `Fill` or resolved `repaymentChainId` is SVM chain. When the resolved `repaymentChainId` is SVM chain, the applied repayment token can be distributed to the associated token account derived from the `relayer` refund address. The relayer can also claim their refunds to any custom token account using the `Fill` `relayer` account as the signer. It is the responsibility of the relayer to ensure it passes the correct `Fill` `relayer` address that they control and that is valid for the resolved `repaymentChainId`. - -### Computing Deposit Refunds -For an expired `Deposit` event, the depositor refund amount shall be computed as `inputAmount` units of `inputToken`. - -### Computing Slow Fill updated output amounts -For the purpose of computing the amount to issue to a recipient for a SlowFill, the relayer fee shall be nulled by applying the following procedure: -- `updatedOutputAmount = (inputAmount * (1 - realizedLpFeePct)) / 1e18`, where `realizedLpFeePct` is computed at the earliest matching deposit's `quoteTimestamp` between `originChainId` and `destinationChainId`. - -#### Constraint -- The `Deposit` `outputAmount` shall _not_ be considered when determining SlowFill amounts. - -#### Note -- The `Deposit` `outputAmount` specifies the exact amount to be received by the `recipient` for a standard fill, and is therefore exclusive of any relayer or LP fees paid. - -### Finding the Opening Running Balance -The Opening Running Balance is defined as the cumulative running balance as at the previous successful (undisputed) Root Bundle Proposal. - -The Opening Running Balance for each unique `l1Token` and `repaymentChainId` pair shall be determined as follows: -1. Search for the preceding [RootBundleExecuted](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol#L157-L166) event where: - 1. The `RootBundleExecuted` `chainId` matches `repaymentChainId`, and - 2. The `l1Token` address appears in the `l1Tokens` array. -2. For the preceding event, identify the index of `l1Token` in the `l1Tokens` array, and lookup the corresponding index in the `runningBalances` array. -3. In the event that no preceding runningBalance is idenfied, the Opening Running Balance shall default to 0. - -### Computing Running Balances & Net Send Amounts -The procedure for computing running balances for an `l1Token` and `chainId` pair shall implement the follows steps: -1. Initialize the running balance to 0. - -2. Add relayer refunds: - - For each group of validated `Fill` and `Pre-fill` events, initialize a running balance at 0 and add the add the relayer repayment. - -3. Add deposit refunds: - - For each group of `Deposit` events that expired or were deemed unfillable within the `Bundle Block Range`, sum the total deposit refunds on the origin chain. Add the amount to the exsting relayer refunds for that chain. - -4. Add slow fills: - - For each group of validated `Slow Fill Requests`, add each slow relay's `updatedOutputAmount` to the group's running balance. - -5. Subtract excesses from unexecuted slow fills: - - For each group of validated `Fills` where the `FillType` is `ReplacedSlowFill` and where there is no valid `Slow Fill Request` with an identical relay data hash in the current bundle data, subtract the SlowFill `updatedOutputAmount` from the running balance in recognition that the SlowFill will never be executed because the fill amount has already been transferred. - - For each expired deposit refund identified above where the `FillStatus` on the deposit destination chain is `RequestedSlowFill` and the matching slow fill request is not in the current bundle range, subtract the associated SlowFill `updatedOutputAmount` from the running balance in recognition that the SlowFill cannot be executed past the `fillDeadline`. - -6. Add the Opening Running Balance for the selected `l1Token` and `chainId` pair. - -8. Set the Net Send Amount and update the Running Balance for each `l1Token` and `chainId` pair subject to the outcome of `Computing Net Send Amounts` as described by the following algorithm: -``` -spoke_balance_threshold = the "threshold" value in `spokeTargetBalances` for this token -spoke_balance_target = the "target" value in `spokeTargetBalances` for this token - -net_send_amount = 0 -# If running balance is positive, then the hub owes the spoke funds. -if running_balance > 0: - net_send_amount = running_balance - running_balance = 0 -# If running balance is negative, withdraw enough from the spoke to the hub to return the running balance to its target -else if abs(running_balance) >= spoke_balance_threshold: - net_send_amount = min(running_balance + spoke_balance_target, 0) - running_balance = running_balance - net_send_amount -``` - -#### Note -The referenced `SpokeTargetBalances` is as specified by [UMIP-157 Token Constants](https://github.com/UMAprotocol/UMIPs/blob/pxrl/umip179/UMIPs/umip-157.md#token-constants): - -## Constructing Root Bundles - -### Constructing the Pool Rebalance Root -One Pool Rebalance Leaf shall be produced per unique `chainId` & `l1Token` pair, where the corresponding `Deposit`, `Fill` or`Slow Fill Request` events were emitted by the relevant SpokePool within the [Bundle Block Range](#identifying-bundle-block-ranges).

This will involve adding the currencies to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 400 USDC per request for USDC and 400 USDT per request for USDT. - -## Motivation -USDT and USDC are the world’s two largest stablecoins by market capitalization as well as traded volume. Both are widely used across the cryptocurrency space, especially on exchanges, where USDC and USDT based crypto-pairs account for a large share of trading volume. - -In comparison to DAI, which is already favored by many in the DeFi community because of its high level of decentralization, USDC and USDT are both fiat-backed stablecoins run by centralized organizations. With centralization comes risk, but the proven success of USDT and USDC, in terms of longevity and size, provide assurance about their ability to maintain value. - -USDC and USDT as collateral types are expected to have a variety of deployments. They will allow for the creation of USD based synthetic assets and will increase the general accessibilty of these assets, as the cryptocurrency market is accustomed to transacting in these currencies. - -## Technical Specification -To accomplish this upgrade, four changes need to be made: - -- The USDC address, 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48, needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 400 needs to be added for USDC in the Store contract. -- The USDT address, 0xdac17f958d2ee523a2206206994597c13d831ec7, needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 400 needs to be added for USDT in the Store contract. - -## Rationale -The rationale behind this change is giving deployers more useful collateral currency options. USDC and USDT are necessary, in addition to the already approved DAI, because of the size of the stablecoin market-share that they own. - -400 was chosen as the final fee for both USDC and USDT because this is practically equivalent to the final fee of already approved stablecoins. - -## Implementation - -This change has no implementation other than proposing the four aforementioned governor transactions that will be proposed. - -## Security considerations -Since USDC and USDT are persistently valuable ERC20 tokens, including both as supported collateral currencies should impose no additional risk to the protocol. - -The main implication is for contract deployers and users who are considering using contracts with USDC or USDT as the collateral currency. They should recognize and accept the centralization risk of using USDC or USDT, as both are fiat-backed or cash-equivalent backed stablecoins run by centralized organizations. USDC is issued and backed by Coinbase and Circle Invest, while USDT is issued and backed by Tether Limited. - -USDT is a non-standard ERC20 as the USDT approve function does not comply with the ERC20 standard. This should not have any immediate security implications, as UMA Protocol contracts use OpenZeppelin's [SafeERC20 wrapper](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/SafeERC20.sol), but should be noted as it *could* have implementation consequences for some financial contracts. - -New price identifiers, that are intended to be used with these collateral currencies, will need to be specified to 6 decimals of precision in order to comply with USDC and USDT. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-180.md b/research/uma/umips/UMIPs/umip-180.md deleted file mode 100644 index 7559c8fd..00000000 --- a/research/uma/umips/UMIPs/umip-180.md +++ /dev/null @@ -1,33 +0,0 @@ -## Headers - -| UMIP-180 | | -| ---------- | ----------------------------------------------------------- | -| UMIP Title | Register Base Parent Messenger in OracleHub and GovernorHub | -| Authors | Pablo Maldonado | -| Status | Approved | -| Created | 03/28/24 | - -## Summary - -This UMIP proposes to register the [Base Parent Messenger](https://etherscan.io/address/0x721bA6f9A0a44657f008f3d68C6dBdDeDBDE831A) with both the [Oracle Hub](https://etherscan.io/address/0x8fE658AeB8d55fd1F3E157Ff8B316E232ffFF372) and [Governor Hub](https://etherscan.io/address/0x94520d90A4EBaA98e5A7B8D6809463f65198C104) to facilitate cross-chain communication and ensure the operational functionality of newly deployed Base contracts, including the Optimistic Oracle. Additionally, it aims to reduce the default gas limit for transactions on both Optimism and Base Parent Messengers from 5 million to 500,000, thus optimizing network efficiency by correcting previously excessive gas allocations. - -## Motivation - -The registration of the Base Parent Messenger with the Oracle and Governor Hubs is critical for enabling cross-chain communications, essential for the operation of Optimistic Oracles and governance processes on Base EVM-compatible network. Moreover, the proposed reduction in the default gas limit addresses inefficiencies in bridging resource usage, aligning gas allocations with actual transaction complexity and network capabilities, leading to optimized operation and lower transaction costs. - -## Technical Specification - -To achieve the goals outlined in this UMIP, the following technical steps will be undertaken: - -- Register the [Base Parent Messenger](https://etherscan.io/address/0x721bA6f9A0a44657f008f3d68C6dBdDeDBDE831A) with the [Oracle Hub](https://etherscan.io/address/0x8fE658AeB8d55fd1F3E157Ff8B316E232ffFF372) and [Governor Hub](https://etherscan.io/address/0x94520d90A4EBaA98e5A7B8D6809463f65198C104).

Details on our current emissions: - -- Emissions Rate: 0.18 UMA per second (5,676,480 UMA per annum) (source: Etherscan) -- Circulating Supply: 84,605,309 UMA (source: CoinGecko) -- Current Inflation Rate: 6.7% -- Cumulative Stake: 21.6M UMA -- Current APY: ~26% -- 30 Day Average Voters (Dec 2024): 280 -- 30 Day Average Voting Power (Dec 2024): 18.4M UMA -- Participation Rate (Dec 2024): 22% (Voting Power / Circulating Supply) -There are several reasons why we think the UMA DAO should reduce emissions: -1. Potential Overpayment: Our current emissions may be higher than necessary to maintain our current staking and voter base. -2. Staker/ Voter Inelasticity: We believe the voting base is relatively inelastic and will likely remain stable even with reduced rates. UMA voters will still earn handsome rewards for their participation in the voting process even if current rates were to half. -3. Reduced sell pressure: Reducing excess UMA supply hitting the market could positively impact the value of the underlying asset. - -## Specification & Implementation - -We propose lowering the emission rate over 3 separate cuts of 0.025 UMA per second, each signed off by individual votes and followed by analysis periods. The terminal emissions rate should not be lower than 0.105 UMA per second (~15% APR). - -This first proposal will involve the following: -1. Cut: reduce emissions by 14% (0.18 UMA/s to 0.155 UMA/s)[~26.3% APR to 22.6% APR] -2. Analysis: assess impact on staking / voting base -- Safeguard: Revert cut and pause further reductions if the 7 day moving average of voters who reveal falls by >20% of the 30 day moving average of the same metric on the day the vote passes. -- Subsequent cuts: Additional 0.025 UMA per second reduction votes if analysis suggests the voting base has not decreased significantly. - -These votes should occur every 2 months until the terminal emissions rate is reached or the safeguard measure comes into effect. - -The recurring proposals should follow this flow: -1. Reporting is posted on discourse for information and discussion with community -2. Snapshot vote starts three days after the above is posted. If passed, move to DVM with bonds sponsored by RL as outlined in the governance docs. -3. DVM vote executes the setEmissionRate function on the VotingV2 contract through UMA DAO’s GovernorV2 contract. - -## Goals - -1. Find the optimal emissions rate that balances rewards and participation -2. Reduce inflation while maintaining a healthy staking ecosystem -3. Improve overall token economics for UMA - -## Potential Downside -If the staking / voting base is more elastic than anticipated this could lead to a reduction in the economic security provided by the Optimistic Oracle as some voters unstake. There is a possibility that these persons exit from the UMA system and do not return. APYs should increase to make it more attractive for new stakers / voters to come in and replace these persons if this occurs. We also have our analysis safeguard in place to revert cuts if the staking base reaction is outsized. - -## Voting - -- A yes vote means that you would like to decrease the emissions rate from 0.18 UMA/s to 0.155 UMA/s. -- A no vote means that you would like to keep the emissions rate at 0.18 UMA/s - -DVM vote to follow if Snapshot vote is successful. diff --git a/research/uma/umips/UMIPs/umip-185.md b/research/uma/umips/UMIPs/umip-185.md deleted file mode 100644 index d25597ae..00000000 --- a/research/uma/umips/UMIPs/umip-185.md +++ /dev/null @@ -1,88 +0,0 @@ -## Headers - -| UMIP-185 | | -| -------------- | ------------------------------------------------------------------------------------------------------ | -| UMIP Title | Upgrade Oracle Request Bridging Contracts | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | April 2, 2024 | -| Discourse Link | [UMA's Discourse](https://discourse.uma.xyz/t/umip-185-upgrade-oracle-request-bridging-contracts/2178) | - -## Summary - -This UMIP proposes to register the upgraded `OracleRootTunnel` and `OracleChildTunnel` contracts for the Polygon network, as well as the upgraded `OracleSpoke` contracts on all the supported optimistic rollup networks. - -## Motivation - -This upgrade is focused on compressing ancillary data as Oracle requests are bridged to Ethereum mainnet, reducing the gas costs for the relayer bots and voting users.

-## Rationale - -The changes introduced in the upgraded `OracleSpoke` and `OracleChildTunnel` contracts are quite similar, so there might be an argument for using the same codebase for optimistic rollup networks and Polygon. Even if migrating Polygon contracts to use hub and spoke model is technically feasible, it is considered to add additional complexity and potential risks to the migration process, hence it is proposed to keep both bridging systems separate. - -During the development process it was also considered to compress the ancillary data only when it exceeds certain threshold, so that the compressed version (including the additional metadata) never exceeds the original ancillary data size. Even if this would have saved some gas costs, it was decided to always use the same ancillary data format to simplify the implementation. Also, based on Q1 2025 data, this would have reduced the gas costs further only in ~2.5% of the cases. - -## Implementation - -When using the upgraded contracts, the ancillary data for bridged Oracle requests will include the following fields: - -- `ancillaryDataHash` - the `keccak256` hash of the original ancillary data -- `childBlockNumber` - the block number on the child network when the Oracle request was originated -- `childOracle` - the address of the bridging contract on the child network (either `OracleChildTunnel` or `OracleSpoke`) -- `childRequester` - the address of the Oracle requester on the child network -- `childChainId` - the chain ID of the child network where the Oracle request was originated - -When observing the `RequestAdded` events on the Ethereum mainnet `VotingV2` contract, if the indexed `requester` field is either the `OracleRootTunnel` or `OracleHub` contract and the `ancillaryData` has above specified fields, the original ancillary data will need to be resolved using the following steps: - -1. Calculate the parent request ID by `keccak256` hashing the ABI encoded `bytes32 identifier`, `uint256 time` and `bytes ancillaryData` from the `RequestAdded` event. -2. Query the `OracleChildTunnel` or `OracleSpoke` contracts (using `childOracle` address) on the child network (referenced by `childChainId`) for the `PriceRequestBridged` event filtering it for the indexed `parentRequestId` field as calculated in the previous step. This log query can be further optimized by limiting the search to the block range from and to the `childBlockNumber` value. -3. Inspect the `ancillaryData` field from the matched `PriceRequestBridged` event from the previous step to obtain the original ancillary data. - -## Security Considerations - -When upgrading smart contracts, it is important to ensure that the new implementation is secure and the migration process is executed correctly. The proposed contract changes have been reviewed by the UMA team and audited by OpenZeppelin. In addition, OpenZeppelin has reviewed the proposed migration payload and UMA team has simulated its execution on the forked networks. - -Following the upgrade, special attention should be taken to all unsettled disputes that were originated before the upgrade and used the old contracts when bridging the requests to Ethereum mainnet. Both `OracleSpoke` and `OracleChildTunnel` contracts have a dedicated `resolveLegacyRequest` function that will be used resolve these disputes after the upgrade. diff --git a/research/uma/umips/UMIPs/umip-186.md b/research/uma/umips/UMIPs/umip-186.md deleted file mode 100644 index a5bfb747..00000000 --- a/research/uma/umips/UMIPs/umip-186.md +++ /dev/null @@ -1,47 +0,0 @@ -| UMIP-186 | | -| ---------- | --------------------------------------------------------------------------------------------------------------------- | -| UMIP Title | Increase SPAT to 65% in VotingV2 Contract | -| Authors | Lee Poettcker | -| Created | April 10, 2025 | -| Discussion | [Discourse](https://discourse.uma.xyz/t/increase-spat-to-65/2177) | - -### Summary -This proposal modifies the Settlement Price Approval Threshold (SPAT) parameter within UMA's VotingV2 contract from 50% to 65%. SPAT is the percentage of staked UMA that needs to agree for a dispute resolution vote to pass. Raising the SPAT means that voters must come to a strong consensus to settle a dispute. Analysis of 2025 voting data shows only 6/291 requests (2%) would have been affected by this change. - -### Background -The Data Verification Mechanism (DVM) currently requires the majority vote to reach a SPAT which is calculated as the majority token weighted vote divided by all staked UMA. If the SPAT is met the dispute is resolved to the majority vote. If the SPAT is not met, the vote “rolls” to the next voting round to be tried again. This continues until the dispute is resolved or the vote rolls 5 times and is subsequently deleted without being resolved. - -### Motivation -The DVM is designed for voters converge on an unambiguous Schelling point. However, the current 50% SPAT allows disputes to resolve where nearly half of participants disagree - a condition that risks enforcing weakly supported outcomes during contentious votes. - -By raising the SPAT, weak majority votes will roll which allows additional time for voters to reconsider their position, UMA community discussion, and requesters can optionally choose to clarify their request. This additional time should help subsequent votes towards a stronger majority that better reflects the Schelling point and is a more reliable dispute resolution. - -This change does increase the risk that votes will roll 5 times and go unresolved which is undesirable. However, this puts pressure on requesters to ensure their requests can be resolved to a strong Schelling point via the original rules or clarifications. - -### Technical Specification -To make the proposed change, the UMA [GovernorV2](https://etherscan.io/address/0x7b292034084a41b9d441b71b6e3557edd0463fa8) contract should call the [VotingV2](https://etherscan.io/address/0x004395edb43efca9885cedad51ec9faf93bd34ac) contract’s [setGatAndSpat](https://etherscan.io/address/0x004395edb43efca9885cedad51ec9faf93bd34ac#writeProxyContract#F19) function with the following arguments: -GAT: 5M UMA (note: unchanged) -SPAT: 65% - -### Rationale -The new SPAT value of 65% was chosen to increase the minimum consensus needed while being below the minimum voter participation and keeping rolled votes relatively infrequent to not overburden voters. - -The voting participation rate in 2025 has averaged 92% with a minimum of 67%. Below is a histogram showing the occurrence of votes by the majority vote share over the last 12 months. As a point of reference, there have been 11 votes with less than 65% majority vote share in 2025. - -***Note: see [Discourse post](https://discourse.uma.xyz/t/increase-spat-to-65/2177) to view histogram.** - -Over the last year, there have been 14 rolled votes. The average majority vote share was 45%. In the second round, 13 of these votes passed and the average majority vote share was 77%. The one remaining vote passed in the third round with a majority vote share of 59%. This shows that as votes get re-rolled UMA voters do typically converge to a stronger consensus. - -A historical analysis of majority vote percentages was performed. A SPAT of 65% was chosen to limit the number of rolled votes and be below the lowest vote participation rates. - -### Security Considerations -This proposal requires no code changes, only a parameter update. Raising the SPAT will also increase the cost of corrupting the DVM as any attack will now require 66% of staked UMA instead of 51%. - -### Risks -A higher SPAT will lead to more rolled votes and therefore more votes. However, as shown in the data above this is expected to be minimal. -Requests that roll will have a longer time to resolution. -Persistently contentious requests that can’t make a >65% majority vote within 5 rolls will be deleted and go unresolved. - -### Implementation -1.

This recent downward trend is not seen in the voting power graph which suggests the voter decline is likely due to small voters leaving after the gas rebate change which required a minimum stake of 500 UMA to be eligible for gas rebates. This change took effect on February 1st, but the first rebate under the new requirements was not paid out until March 13th. So many small voters may not have been aware of the change until mid March. - -A better measure of the effect of the UMA Emission Reduction is to look at the number of addresses voting with over 500 UMA (see chart at Discourse link above). This removes the effect of the gas rebate minimum and only takes into account addresses that have enough stake to meaningfully contribute to UMA’s staking decentralization.

This allows the integration to have easier access to functionality already present in OptimisticOracleV2 without diminishing the role of UMA governance over the new contract. If passed, this UMIP will approve a ManagedOptimisticOracleV2 managed by Polymarket to send disputes to UMA’s Data Verification Mechanism (DVM) for UMA stakers to resolve. - -## Motivation -The current OptimisticOracleV2 contract allows integrations to revise a request’s bond amount, liveness, and who can propose, but requires these changes to be made through the integration’s requesting contract. This requirement has made it more difficult for integrations to manage their requests as easily as they would like. - -The new ManagedOptimisticOracleV2 contract is designed to be used by a single integration and gives the integrator admin access to easily modify the bond, liveness, and who can propose for all of their requests. - -## Technical Specification -All new oracle deployments must be given permission by the UMA DAO to send their disputes to the DVM for resolution.

A summary of the changes from OptimisticOracleV2 is given below. - -The ManagedOptimisticOracleV2 is intended to only serve a single integration. The integrator can more easily access functionality that is already supported in OptimisticOracleV2 via two new roles: -- **owner**: a high security address that can: - - add and remove request managers - - set the default proposer whitelist which applies all new requests - - set the requester whitelist which controls who can make requests - - set the minimum liveness and minimum / maximum bond that the request manager can set a request to - -- **requestManager**: address used more frequently to: - - revise an unproposed request’s bond size, liveness and set the proposer whitelist - -The newly deployed ManagedOptimistOracleV2 contract to be approved by this UMIP will be upgradable via a 2/2 multisig consisting of Polymarket and Risk Labs. - -UMA DAO governance will still have all the same parameter controls it has over the standard OptimisticOracleV2 contract, such as approving new bond collaterals and price identifiers, and setting final fees for a given bond collateral. - -## Security Considerations -ManagedOptimisticOracleV2 includes minor changes to the long running and previously audited OptimisticOracleV2 contract. ManagedOptimisticOracleV2 is undergoing an internal audit that will be completed before this UMIP proceeds to an onchain vote with an OpenZeppelin audit to follow ASAP. If this UMIP passes, this contract should only be used for low risk use cases until the OpenZeppelin audit has been completed. - -## Voting -**YES**: approve the ManagedOptimisticOracleV2 at `0x2C0367a9DB231dDeBd88a94b4f6461a6e47C58B1` managed by Polymarket to send disputes to the DVM. -**NO**: do NOT approve the ManagedOptimisticOracleV2 at `0x2C0367a9DB231dDeBd88a94b4f6461a6e47C58B1` managed by Polymarket to send disputes to the DVM. diff --git a/research/uma/umips/UMIPs/umip-19.md b/research/uma/umips/UMIPs/umip-19.md deleted file mode 100644 index 8d636fe0..00000000 --- a/research/uma/umips/UMIPs/umip-19.md +++ /dev/null @@ -1,72 +0,0 @@ -## Headers -| UMIP-19 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add ARSUSD as a price identifier | -| Authors | Sean Brown (sean@umaproject.org) | -| Status | Approved | -| Created | October 28, 2020 | - -## Summary (2-5 sentences) -The DVM should support price requests for the ARS/USD price index. - - -## Motivation -The DVM currently does not support the ARS/USD price index. - -Supporting the ARSUSD price identifier would enable the creation of an Argentine Peso stablecoin, backed by USD.

Ripio and SatoshiTango are Argentinian cryptocurrency exchanges and were chosen because they have some of the highest genuine volumes of ARS/BTC trading. CoinMonitor is a price aggregator that determines its ARS/BTC price as a result of taking the median of a group of buy and a group of sell prices from various cryptocurrency exchanges and then averaging the two. CoinMonitor was chosen as a data source because its price calculation methodology creates a good representation of what the true market rate for BTC/ARS is. All three sources offer free and publicly accessible historical BTC/ARS endpoints. - -The decision, to query for BTC/ARS and BTC/USD instead of directly querying for ARS/USD, was made because the ARS/USD pair has a large variance in price reporting, caused by artificial factors. Products built with the ARSUSD price identifier are most likely to be used in Argentinian cryptocurrency exchanges, so the price identifier should use the price reflected by the highest volume crypto-native ARS trading pair. - -More explicitly, the choice to use BTC/ARS over ARS/USD has to do with the fact that Argentina is currently under a capital restrictions scheme, where retail users and companies cannot access the official exchange rate to buy goods or services. Because of this situation, there are several USD/ARS rates currently within a ~100% spread between the official and unofficial rate. Since this rate will be used to create crypto assets, we consider the fair USD/ARS exchange rate to be the one which you can access to purchase cryptocurrencies. BTC/ARS is the pair with the majority of the trading in the country, with an estimate of 80% of the total volume, with more than 10 different brokers operating daily in the country. Correctly assessing the USD/ARS exchange rate is a complex task and probably will be even more complex in the near future. Since synthetic ARS by nature would be used in cryptocurrency transactions, the argument is that the best approach would be to have the value of synthetic ARS track the rate that a crypto user would get by exchanging ARS into BTC and then BTC into USDC (or an equivalent). - -## Implementation - -The value of ARSUSD for a given timestamp can be determined with the following process. - -1. BTC/ARS should be queried for from the endpoints below for the given timestamp rounded to the nearest available endpoint time value. The results of these queries should be kept at the level of precision they are returned at. -2. The median of the BTC/ARS results should then be taken. -3. The inverse of the BTC/ARS mean is then taken (1/BTCARS) to determine ARS/BTC. -4. The value of BTC/USD for the same timestamp will then need to be determined by following the implementation guidelines defined in UMIP-7. -5. The values of ARS/BTC and BTC/USD will then need to be multiplied to arrive at the ARSUSD value. As specified in the ‘Technical Specification’ section, this result should be rounded to six decimal places. - -The chosen historical BTC/ARS endpoints are: - -| Endpoint | Field name of price | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| https://app.ripio.com/api/v3/public/currencies/BTC/history/ARS/ | *price* | -| https://api.satoshitango.com/v3/ticker/ARS/BTC/history | *avg* | -| https://ar.coinmonitor.info/api/v4/btc_ars/?periodo=96hs | *p* | - - -Voters are responsible for determining if the result of this process differs from broad market consensus. This is meant to be vague as $UMA tokenholders are responsible for defining broad market consensus. - -This is only a reference implementation, how one queries the exchanges should be varied and determined by the voter to ensure that there is no central point of failure. - -## Security considerations -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-190.md b/research/uma/umips/UMIPs/umip-190.md deleted file mode 100644 index 2b325b94..00000000 --- a/research/uma/umips/UMIPs/umip-190.md +++ /dev/null @@ -1,503 +0,0 @@ -## Headers - -| UMIP-190 | | -| ------------------- | --------------------------------------------------------------- | -| **UMIP Title** | Currency Whitelist Maintenance and Fee Updates | -| **Authors** | UMA Protocol Team | -| **Status** | Draft | -| **Created** | August 28, 2025 | - ---- - -## Summary - -This UMIP proposes whitelist housekeeping across Ethereum mainnet, Polygon, Arbitrum, Optimism, Base, and Blast: - -- **Remove** a defined set of deprecated currency addresses from each network’s whitelist. -- **Reset final fees to 0** for removed currencies. -- **Update final fees** for WETH on all supported chains, and for ABT on mainnet. -- **Retire Boba messenger support** (chainId **288**) on mainnet. - -To keep on-chain proposals small and auditable, these changes are executed via **four separate proposals** (Parts 1–4). The canonical action lists are included below. - ---- - -## Motivation - -Over time, UMA’s currency whitelists accumulate assets that are no longer actively used. Periodic housekeeping removes inactive entries and simplifies operations. This UMIP performs: - -- **Whitelist pruning** of currencies that are not actively used on mainnet, Polygon, Arbitrum, Optimism, Base, and Blast. **Note: these currencies could be re-whitelisted in the future if use cases arise.** -- **Fee table alignment** for actively used currencies (WETH, USDC, ABT). -- **Removal of Boba chain support** by retiring the Boba messenger. - -No protocol semantics change and no new functionality is introduced—this is a standard clean-up and parameter alignment exercise. - ---- - -## Technical Specification - -All actions are executed through the standard UMA Governor process on each network. - -### Common operations - -- **Remove currency from whitelist:** - `removeFromWhitelist(address collateral)` -- **Set/Reset final fee:** - `setFinalFee(address currency, FixedPoint.Unsigned memory newFinalFee)` - (For removed currencies, `newFee = 0`.) -- **Retire messenger (mainnet):** - Remove Boba **chainId 288** from supported

@@ -## Headers - -| UMIP-191 | | -| -------------- | ------------------------------------------------------------------------ | -| UMIP Title | Add `ASSERT_TRUTH2` as a supported price identifier | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Draft | -| Created | November 28, 2025 | -| Discourse Link | https://discourse.uma.xyz/t/feat-umip-191-whitelist-assert-truth2/2244 | - -# Summary - -The DVM should support price requests for the `ASSERT_TRUTH2` price identifier. `ASSERT_TRUTH2` is intended to work the - same as `ASSERT_TRUTH` which was whitelisted as part of [UMIP-170](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-170.md). - -This UMIP allows asserters to make claims about the state of the world. It does not attempt to put any restrictions on - the types of claims that can be made, but rather focuses on the mechanics of how the DVM should be used to resolve - disputes over such claims. - -Price settlement can happen only in one of two ways: - -- Return the `1` value if the claim is true and publicly verifiable. -- Return the `0` value if the claim is false or cannot be resolved. - -# Motivation - -This price identifier is intended as a one for one replacement of the retired `ASSERT_TRUTH` price identifier. It will - allow integrating partners to build their products on top of UMA's Optimistic Oracle V3 contract. This will allow their - users to make claims about the state of the world and resolve disputes over these claims in a trustless manner. - -# Data Specifications - -It is not possible to define specific data sources or markets for this identifier. Determination of data sources and - results are left entirely up to potential disputers and voters as the best method of determining the results will - depend on the claim being made. - -# Price Feed Implementation - -No price feed is needed (or possible) for this price identifier. - -# Technical Specifications - -- Price identifier name: ASSERT_TRUTH2 -- Base Currency: NA -- Quote Currency: NA -- Rounding: None, there is a predetermined set of results. -- Estimated current value of price identifier: NA - -## Ancillary Data Specifications - -Upon dispute the following ancillary data parameters will be available to the voter after converting it from bytes to - UTF-8: - -- `assertionId`: The ID of the assertion being disputed. -- `ooAsserter`: The address of the asserter that made the claim. - -If the assertion was disputed on any other chain than Ethereum mainnet, the original ancillary data has to be resolved - first from `PriceRequestBridged` event emitted on the child chain using the procedure as outlined in [UMIP-185](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-185.md). - -# Rationale - -This construction sacrifices assurances of determinism in favor of greater price identifier flexibility. This places the - burden of correct construction on claims being asserted, but, in return, allows for quicker and easier development - without needing to pass through UMA governance for each additional application that builds on top of Optimistic - Oracle V3 contract. - -# Implementation - -1. Voters should identify the Optimistic Oracle V3 contract that was used to make and dispute the assertion. This can be - done by calling `getImplementationAddress` on the `Finder` contract with the `OptimisticOracleV3` identifier encoded as - `bytes32` at the time of DVM request. The address of the `Finder` contract depends on the network where the dispute was - raised and is available in the `networks` directory of the UMA [protocol repository](https://github.com/UMAprotocol/protocol/tree/master/packages/core/networks). -2. Voters should decode the ancillary data of the request and determine its `assertionId` parameter. -3. Voters should search the `AssertionMade` event emitted by the Optimistic Oracle V3 contract from Step 1 for an - assertion with the matching `assertionId` parameter from Step 2. Take a note of the timestamp of this event and its - `claim` parameter, as well as any other relevant fields needed to resolve the dispute. -4. Voters should attempt to decode the `claim` parameter from Step 3 as UTF-8 string. If the decoding fails, the claim - is not a string that can be asserted truthful, and voters should return the `0` value. -5. The decoded `claim` string from Step 4 could include references to the timestamp that was used to make the assertion. - If not present, voters should assume that the timestamp of the `AssertionMade` event from Step 3 should be used. -6.

Calculating, for example, Bitcoin dominance involves knowing the current supply of bitcoin, the prevailing market price of BTC/USD, and the total market capitalization of all tokens in USD. More importantly, calculating the total market capitalization of all tokens in USD is a challenge since different data sources may altogether not include particular alt-coins thereby affecting all coin market dominance percentages. - -At the moment, Bitcoin dominance is commonly referenced through three major sources: TradingView, CoinMarketCap & CoinGecko. However, unlike trading pairs which exhibit strong redundancy without deviation largely due to arbitrage incentives, each data source can vary by multiple percentage points due to differing calculation methodologies. Namely, each site has different methodologies for which alt-coins to admit into the total market cap, and a given coin’s market price and total coin circulation amounts may differ, compounding over hundreds or even thousands of alt-coins. Additionally, on a technical note, live and historical data update frequency varies and historical data may be paywalled, making it significantly harder to successfully run liquidation and dispute bots with redundancy and without paying for API access. To make matters worse, had we proposed a scheme where multiple data sources were used, we’d have to decide on using either the median or mean of the data sources and then have to specify some logic to handle if one of the data sources went down or starting to significantly different from the rest, for example. - -In an effort to alleviate these challenges, the Domination Finance team was able to get in touch with Bobby & TM, the cofounders of CoinGecko. The CoinGecko team went above and beyond to meet the requisites, updating CoinGecko’s coin dominance live data to 1-3 minute intervals from what was previously 10 minutes. Although this may introduce a single point of failure, we felt that the costs in increased complexity and mental load on the stakeholders who need to use it (like speculators, sponsors, liquidators & disputers) outweighed the benefits, especially during this period where the synthetic token is newly launched. - -While CoinGecko was able to provide the higher time granularity for coin dominance on short notice, historical data, necessary for dispute bots and voters, was unable to be immediately supplied from CoinGecko. Instead, constructing a separate caching service is necessary to track and record the historical data from polling the CoinGecko live API to be able to compute historical coin dominance at a given point in time. This stop gap measure should be more than sufficient to provide the historical data for dispute bots and voters.

Additionally, if the contract using this price identifier is an expiring contract, inputs will change depending on the price request timestamp in comparison to the expiry timestamp. -- Price Steps: 1 Wei (1e-18) -- Pre-Timestamp Price Rounding: N/A because the median algorithm and query as described in the UMIP-16 implementation section cannot produce numbers with higher precision than 1 Wei (1e-18). -- Post-Timestamp Price Rounding: Closest, 0.5 up -- Pricing Interval: 1 second -- Dispute timestamp rounding: down -- Scaling Decimals: (1e18) - -## Rationale - -Please reference the Rationale section in UMIP-16 and UMIP-20 for a full walkthrough of the rationale behind calculating aggregatory gas prices. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because a synthetic token, that is trading based on the future price of an underlying index, will have its price affected by expectations of the future movement of the underlying. If there is a large discrepancy in the synthetic’s price and the underlying index, arbitrageurs could take advantage of the difference in price by minting tokens at a rate determined by the underlying, abandoning their collateral to be liquidated and selling the tokens at the higher trading rate. Additionally, if a token is trading at a price that is higher than the notional value of the backing collateral, there would be no economic incentive for a liquidator to perform a liquidation. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -## Implementation - -If the price request's UTC timestamp is less than `1625097600`, voters will need to calculate a 2-hour TWAP for the uGAS token's price in ETH. The following process should be used to calculate the TWAP. - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the ETH/uGAS pool returns at the end of the latest block whose timestamp is <= the timestamp that is queried for. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. As the token price will already implicitly be tracking the GASETH-1M-1M price, it should be left as returned without any scaling transformation. -6. The final price should be returned with the synthetic token as the denominator of the price pair and should be submitted with 18 decimals. - -If the price request's UTC timestamp is at or after `1625097600`, a price request for GASETH-TWAP-1Mx1M will follow the calculation methodology for the GASETH-1M-1M identifier defined in the UMIP-20 Rationale and Implementation sections. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. This feed should be used as a convenient way to query a realtime or historical price, but voters are encouraged to build their own off-chain price feeds. - -## Security considerations - -Security considerations pertaining to calculating an aggregate gas price are covered in the Security Considerations section of [UMIP-16](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-16.md). - -There are two general security considerations for using a token price for collateralization. - -1. **Token price manipulation** - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradeable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -2. **Mismatch between TWAP and gap higher in token price** - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations - as the 30-day median gas price should be slow moving by design - or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uGAS, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -This is the first DVM supported price identifier of its kind, so synthetic token holders should proceed with caution when interacting with a contract using this identifier. Security considerations, like the ones above, have been contemplated and addressed, but there is potential for security holes to emerge due to the novelty of this price identifier. - -Additionally, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders.

Further, given the large interest in iBCH, relative to the other i* synthetics on Synthetix, there exists empirical evidence that there is strong retail demand in the eth defi community to express short interest on BCH. Lastly, given the current regime, empirically retail has viewed BCH as levered beta on BTC which will fuel the longs for this synthetic minting. - -There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available. - -## Technical Specification -The definition of this identifier should be: - -- Identifier name: BCHNBTC -- Base Currency: BCHN -- Quote Currency: BTC -- Data Sources: Binance, Coinbase Pro, Huobi -- Result Processing: Median of BCH/BTC -- Input Processing: None.

Most exchanges, namely the three we listed there for constructing the price, only view BCHN as the dominant fork, so their convention of BCH is just referring to BCHN, as is indicated in the hyperlinks. The objective was to construct a portfolio of liquid price feeds that maximized geographical diversity as well as user base with negatively/zero correlated downtimes. Binance and Huobi are widely regarded as the most liquid and highest ADV exchanges in the world, and have been so for quite some time. Further, each of the exchanges has "crypto SOTA" APIs with free REST + WSS functionality with generous rate limits and robust endpoints for prices that any user may hit, both real time and historically speaking. Further, Coinbase Pro has a fairly orthogonal user base to the above exchanges and serves as an additive signal to a notion of "fair value" of BCH/BTC, along with a user friendly API. All three of these exchanges have 24/7 customer support + devops team ensuring highly available programmatic access and have strong redundancy across a variety of geographies. Lastly, because Binance and Huobi also have the most liquid derivatives market for both BCH and BTC pairs, users on their platforms should be able to arbitrage the BCHN uma synths if they so please, thereby increasing popularity of these synthetics. - -The decision to query for BCH/BTC instead of BCH/USD is due to three main reasons. Mostly BTC denominated users want to be able to express short-dated interest in the SHA256d coin space, particularly of BCHN given the recent hard fork. Also, from a capital efficiency standpoint, it is important to notice the magnitude of the correlation between BTC and BCH, which has been strong and positive (1 year perason correlation is approximately 0.75) in all bullish regimes of crypto. Given this, users are able to get by with thinner collateral ratio requirements given that they both tend to trend to together. In other words, more formally, the relative volatility of BCH/USD exceeds that of BCH/BTC by a stat sig amount given the positive correlation between them. Lastly, the use of BCH/USD with BTC as collateral would have resulted in a quanto effect where there would be embedded convexity (correlation conditional gamma) that users would have to either hedge out or be forced to take a view on. Given the only liquid place to hedge that is on Bitmex, and due to their recent legal troubles, we decided it would be inconvenient to impose that on users. Further, while we are no strangers to quanto derivatives, the core thesis here isn't to productize BCH-BTC correlation. - -## Implementation - -The value of BCHBTC for a given timestamp can be determined with the following process. - -1. BCH/BTC should be queried for from Binance, Huobi, and Coinbase Pro for the given timestamp rounded to the nearest second. The results of these queries should be kept at the level of precision they are returned at. -2. The median of the BCH/BTC results should then be taken. -3. This result should be rounded to eight decimal places. - -Additionally, [CryptoWatch API](https://docs.cryptowat.ch/rest-api/) is a useful reference.

As an example, a voter should use the Friday XAUUSD closing price for a price request that happens in off-market hours on a Saturday. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -## Security considerations -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-27.md b/research/uma/umips/UMIPs/umip-27.md deleted file mode 100644 index 8ce6f931..00000000 --- a/research/uma/umips/UMIPs/umip-27.md +++ /dev/null @@ -1,33 +0,0 @@ -## Headers -| UMIP-27 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Approve Patched EMP Financial Contract Template | -| Authors | Matt Rice (matt@umaproject.org) | -| Status | Approved | -| Created | December 14, 2020 | - -## Summary -This UMIP will have the effect of introducing an updated ExpiringMultiParty contract template that matches the one introduced in UMIP-14, but with [this](https://github.com/UMAprotocol/protocol/pull/2203) bug fix. - -## Motivation & Rationale - -This UMIP was motivated by a bug report that revealed that the liveness-reset feature introduced in UMIP-14 did not work as intended due to a reversed inequality. - -## Technical Specification -To accomplish this upgrade, a new financial contract template must be deployed. - -Deployment address: https://etherscan.io/address/0xB3De1e212B49e68f4a68b5993f31f63946FCA2a6. - -After deployment, this new `ExpiringMutltiPartyCreator` contract should be approved as a ContractCreator in the Registry. - -Note: the voters only vote for the approval -- the deployment has no effect on the protocol until added as a ContractCreator. - -## Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/core/contracts/financial-templates/expiring-multiparty).

STABLESPREAD is defined as: `min(max(A - B + 1, 0), 2)`, where `A` refers to an equally weighted basket of {UST, CUSD, BUSD}. B is an equally weighted basket of {USDC, USDT}. UST is TerraUSD, the interchain stablecoin connected by the Cosmos IBC. CUSD is Celo Dollar, the stablecoin on the Celo network. BUSD is Binance USD, a stablecoin issued by Paxos in partnership with Binance. `USDC` is a centralized stablecoin issued by Circle and Coinbase. `USDT` is a non-transparent centralized stablecoin issued by Tether, currently the most used stablecoin on Ethereum. - -## Motivation -The DVM currently does not support the STABLESPREAD price index. - -Supporting the STABLESPREAD price identifier would enable the creation of a linear combination of stablecoin baskets, both existing on Ethereum and other blockchains. Token minters could go short on the STABLESPREAD index, while token holders could go long or use synthetic STABLESPREAD for functional purposes. - -There has been an increasing growth of non-Ethereum based stablecoins over the last few months, and especially over the last week in the case of UST, given the Mirror launch earlier this week. Each of these stablecoins have their own quirks and mechanisms in which they aim to target their peg. There appears to be somewhat of a growing dichotomy in terms of folks who believe that non-Ethereum based stable coins are able to retain their peg better. Currently, there does not exist a mechanism for users to express a view on the relative performance of which basket of stablecoins actually retains it peg better without actually acquiring the underlying constituents of the long basket and picking up a synthetic short position of the other basket. - -Further, we also believe STABLESPREAD can act as a defi credit spread primitive where folks can build other products on top, such as an insurance based product where the premium of the insurance is tied to the divergence between the two baskets of stablecoins. Additionaly, one can view the probability of default of a stablecoin as `1 - min(price, 1)`. Given that each basket of stablecoins is a convex combination, then it is also a convex combination of default probabilities. STABLESPREAD is then a difference of convex combination of default probabilities. We also believe that a CDS (credit default swap) can be built on top of this since they are effectively a function of default probabilities, and once STABLESPREAD gets whitelisted as a price identifier, we will start development on such products. - -Let's walk through some cases to better understand what happens in various cases for STABLESPREAD. If both of these baskets were to trade at their theoretical value, then the resulting value of STABLESPREAD will be 1. If the Ethereum based stablecoin basket loses its peg and appreciates in value relative to the non-Ethereum stablecoin basket, then the value of STABLESPREAD will be less than 1. If the opposite happens, then it will be more than 1. It is important that this only measures "relative ability to maintain peg". That is, if both of them lose their peg in the same form, the resulting value still may be 1. - -There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available. - -## Technical Specification -The definition of this identifier should be: - -- Identifier name: STABLESPREAD -- Base Currency: STABLESPREAD -- Quote Currency: ETH -- Data Sources: {Bittrex: UST/USDT, Uniswap V2: UST/USDT} for UST, {Binance: BUSD/USDT, Uniswap V2: BUSD/USDT} for BUSD, {Bittrex: CUSD/USDT} for CUSD, {Bitfinex: UST/USD, Kraken: USDT/USD} for USDT, {Kraken: USDC/USD, Bitstamp: USDC/USD} for USDC, {Coinbase: ETH/USD, Bitfinex: ETH/USD} for ETH -- Result Processing: For each constituent asset of the basket, the average of both exchanges -- Input Processing: None. Human intervention in extreme circumstances where the result differs from broad market consensus. -- Decimals: 8 -- Rounding: Closest, 0.5 up -- Pricing Interval: 1 second -- Dispute timestamp rounding: down -- Scaling Decimals: 18 (1e18) - -## Rationale -Prices are primarily used by Priceless contracts to calculate a synthetic token’s redemptive value in case of liquidation or expiration. Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. - -For each of the constituents of STABLESPREAD- UST, CUSD, BUSD, USDC, USDT, we picked the two most liquid exchanges, including both CeFi and DeFi sources for diversity. Further, each of the CeFi exchanges has "crypto SOTA" APIs with free REST + WSS functionality with generous rate limits and robust endpoints for prices that any user may hit, both real time and historically speaking. Most of these CeFi exchanges have 24/7 customer support + devops team ensuring highly available programmatic access and have strong redundancy across a variety of geographies. On the DeFi side, Uniswap V2 and Balancer are widely regarded as high quality AMMs. - -The objective for STABLESPREAD was to construct a portfolio of the most liquid and active non-Ethereum based stablecoins, and rather than using some complicated weighting scheme, we are initially imposing uniform weighting. If it turns out there is some user feedback around doing a market-cap weighting, ADV-weighting, etc. that can be future work for us. We also experimented with a variety of functional forms of computing a divergence of these two baskets to represent a credit spread. Computing the ratio of them had some promising properties, namely non-negativity constraints, but the nonlinearity of it had some subpar properties that might cause unfriendly UX as liquidations might cascade if the denominator went down X% as opposed to the numerator. So, we settled on an affine transformation, where if both baskets are indeed the same then the result will be 1. - -## Implementation - -The value of STABLESPREAD for a given timestamp can be determined with the following process. - -1. UST, CUSD, BUSD, USDT, USDC should be queried for from the exchanges listed in the "Technical Specification" section for the given timestamp rounded to the nearest second. The results of these queries should be kept at the level of precision they are returned at. -2. For each one, the average of the prices should be calculated. -3. Then, calculate 1/3 * UST + 1/3 * CUSD + 1/3 * BUSD, denote this as `A` -4. Next, calculate 1/2 * USDC + 1/2 * USDT, denote this as `B` -5. Perform A - B + 1 -6. Perform the maximum of the result of step 4 and 0. This is to ensure non-negativity. -7. Perform the minimum of the result of step 5 and 2. This is to ensure symmetry. -8. Take the result of step 6 and divide by the value of ETH/USD. -9. This result should be rounded to eight decimal places. - -Additionally, [CryptoWatch API](https://docs.cryptowat.ch/rest-api/) is a useful reference. This feed should be used as a convenient way to query the price in realtime, but should not be used as a canonical source of truth for voters. Users are encouraged to build their own offchain price feeds that depend on other sources. - -Voters are responsible for determining if the result of this process differs from broad market consensus. This is meant to be vague as $UMA tokenholders are responsible for defining broad market consensus. - -This is only a reference implementation, how one queries the exchanges should be varied and determined by the voter to ensure that there is no central point of failure. - -As an example of how one may go about constructing such a feed programmatically, here is one that was put together as a standalone script with minimal dependencies: https://gist.github.com/chicfilabae/3dff8aef233e4b9e5315daa7a835867d. As always, double-check the implementation as well as include additional measures for reliability to ensure reasonable assumptions around when the graph or cryptowatch isn't available. - -## Security considerations -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users given this is dealing with some of the most liquid stablecoins in the whole cryptoverse, and the relative price volatility of them has been rather low due to their stablecoin properties. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders.

Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as a official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds.

Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of EURUSD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap on EUR/USD, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. - -In the past the CHF was pegged to the EUR, but in 2015 this pegged was removed by the Swiss Central Bank in a surprise move, which caused a huge volatile movement on the CHF price. Such movement could put the CHF below the 100% collateralization ratio, although it is highly unlikely to happen. This risk could appear again one day if the peg is reinstated. In the forementioned situation the CHF lost 20% within one day. However with a higher required collateralization ratio such events can be mitigated. diff --git a/research/uma/umips/UMIPs/umip-3.md b/research/uma/umips/UMIPs/umip-3.md deleted file mode 100644 index d168aaed..00000000 --- a/research/uma/umips/UMIPs/umip-3.md +++ /dev/null @@ -1,242 +0,0 @@ -## Headers -UMIP 3 -

ELASTIC_STABLESPREAD/USDC is defined as: `min(max(A - B + 1, 0), 2)`, where `A` refers to an equally weighted basket of {ESD, FRAX, BAC}. B is an equally weighted basket of {USDC, USDT}. ESD is Empty Set Dollar, an algorithmic stablecoin on Ethereum with a dynamic supply model. FRAX is a fractional-algorithmic stablecoin on Ethereum that operates on a creative approach to maintaining a peg via a partially collateralized approach. BAC is Basis Cash, a dynamic supply stablecoin on Ethereum, essentially a version of what the original Basis project meant to be a few years ago. `USDC` is a centralized stablecoin issued by Circle and Coinbase. `USDT` is a non-transparent centralized stablecoin issued by Tether, currently the most used stablecoin on Ethereum. - -## Motivation -The DVM currently does not support the ELASTIC_STABLESPREAD/USDC price index. - -Supporting the ELASTIC_STABLESPREAD/USDC price identifier would enable the creation of a linear combination of stablecoin baskets, both traditional Ethereum-based stablecoins as well as newer elastic-supply based models on Ethereum. Token minters could go short on the ELASTIC_STABLESPREAD/USDC index, while token holders could go long or use synthetic ELASTIC_STABLESPREAD/USDC for functional purposes. - -There has been an increasing growth of seigniorage + elastic-supply based stablecoins over the last few months, and especially over the last few weeks given the success of ESD's launch. Each of these stablecoins have their own quirks and mechanisms in which they aim to target their peg. Historically, it appears that the elastic-supply based stablecoins are more susceptible to feedback loops where they will stay above their peg for an extended period of time or below their peg for an extended period of time. Currently, most of these are trading at a premium. Users will now be able to speculate on the "premium" of the seigniorage model for elastic supply based stablecoins. Currently, there does not exist a mechanism for users to express a view on the relative performance of which basket of stablecoins actually retains it peg better without actually acquiring the underlying constituents of the long basket and picking up a synthetic short position of the other basket. - -Further, we also believe ELASTIC_STABLESPREAD/USDC can act as a defi credit spread primitive where folks can build other products on top, such as an insurance based product where the premium of the insurance is tied to the divergence between the two baskets of stablecoins. Additionaly, one can view the probability of default of a stablecoin as `1 - min(price, 1)`. Given that each basket of stablecoins is a convex combination, then it is also a convex combination of default probabilities. ELASTIC_STABLESPREAD/USDC is then a difference of convex combination of default probabilities. We also believe that a CDS (credit default swap) can be built on top of this since they are effectively a function of default probabilities, and once ELASTIC_STABLESPREAD/USDC gets whitelisted as a price identifier, we will start development on such products. - -Let's walk through some cases to better understand what happens in various cases for ELASTIC_STABLESPREAD/USDC. If both of these baskets were to trade at their theoretical value, then the resulting value of ELASTIC_STABLESPREAD/USDC will be 1. If the Ethereum based stablecoin basket loses its peg and appreciates in value relative to the non-Ethereum stablecoin basket, then the value of ELASTIC_STABLESPREAD/USDC will be less than 1. If the opposite happens, then it will be more than 1. It is important that this only measures "relative ability to maintain peg". That is, if both of them lose their peg in the same form, the resulting value still may be 1. - -There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available. - -## Technical Specification -The definition of this identifier should be: - -- Identifier name: ELASTIC_STABLESPREAD/USDC -- Base Currency: ELASTIC_STABLESPREAD -- Quote Currency: USDC -- Data Sources: {Uniswap V2: FRAX/USDC} for FRAX, {Uniswap V2: ESD/USDC} for ESD, {Uniswap v2: BAC/DAI} for BAC, {Bitfinex: UST/USD, Kraken: USDT/USD} for USDT, {Coinbase-Pro: DAI/USD, Kraken: DAI/USD} for (Multi Collateral) DAI, {Kraken: USDC/USD, Bitstamp: USDC/USD} for USDC -- Result Processing: For each constituent asset of the basket, the average of exchanges.

If it turns out there is some user feedback around doing a market-cap weighting, ADV-weighting, etc. that can be future work for us. We also experimented with a variety of functional forms of computing a divergence of these two baskets to represent a credit spread. Computing the ratio of them had some promising properties, namely non-negativity constraints, but the nonlinearity of it had some subpar properties that might cause unfriendly UX as liquidations might cascade if the denominator went down X% as opposed to the numerator.

Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. diff --git a/research/uma/umips/UMIPs/umip-33.md b/research/uma/umips/UMIPs/umip-33.md deleted file mode 100644 index ee18793c..00000000 --- a/research/uma/umips/UMIPs/umip-33.md +++ /dev/null @@ -1,183 +0,0 @@ -# Disclaimer - -The AMPLUSD price identifier has been deprecated.

Part of Ampleforth’s rebase mechanism uses a market oracle, Chainlink, for price feeds.

Adding this functionality provides our users with a better UX, due to the fact that there won't be multiple versions of the same synthetic asset even if a new derivative contract is deployed for that synthetic asset, thus there won't be the need for users or liquidity providers to transfer their funds in order to back another synthetic asset. -Giving `Creator` role to `DerivativeFactory.sol` would allow our synthetic assets to be backed by the UMA liquidation/dispute system, since every newly deployed derivative (`PerpetualPoolParty.sol`) is registered with the DVM. - -# Technical Specification - -### Here is a breakdown on the whole deployment process of a new derivative: - -1.

Adding this contract as Creator role in UMA registry, allow the derivatives deployed to integrate the DVM -- When deploying a new derivative contract (`SynthereumPerpetualPoolParty.sol`) the `SynthereumDerivativeFactory.sol` can set any ERC-20 token as collateral, meaning that it allows the support of multiple collateral tokens including those that accrue interest (inflationary). This adds additional flexibility to the contract in maintaining a collateral currency which is preferred by the community and also most stable in terms of technical risks. -- The forked and updated version of `SynthereumPerpetual.sol`, now called `SynthereumPerpetualPoolParty.sol`, deployed by `SynthereumDerivativeFactory.sol` is set with gas optimization in mind. Due to adding more functionalities to it the gas limit for deployment was overpassed, so the overall architecture was changed by using library contracts which hold some of the functionalities, thus significantly lowering the gas costs of deployment. -- Removing of `fundingRate` as a functionality from the `Perpetual.sol`(`SynthereumPerpetualPoolParty.sol`), since we do not need such feature in order to maintain the peg; Synthereum's synthetic assets are always redeemable for their exact value in collateral tokens against a price feed, insuring constant arbitrage, and therefore a strong peg. -- Two types of roles were set-up in the `SynthereumPerpetualPoolParty.sol` which is deployed by the `SynthereumDerivativeFactory.sol` - Admin and Pool.

As example a possibility for an attacker to exploit our protocol, which could potentially drain capital from PerpetualPoolParty contract, thus rendering synthetic assets linked to those pools become undercapitalized (collateralization ratio to drop below 100%) and therefore becoming worthless. In order to mitigate this as we mentioned we'll cap the system until we are fully audited and have ran several whitehack test and also we'll be adding a daily withdraw limitation, so even in the worse case scenario we as a foundation can cover the losses of users. We'll also purchase cover on that limit using various protocols (Nexus, Unslashed) as well as setting up our own insurance fund. - -Currently there is no economical incentive for liquidating undercapitalized positions (positions where the CR drops below 100%).

The “expansion” only goes to users who have tokens bonded (staked) in the dao or to liquidity providers who have bonded the lp tokens to the app. The tokens are claimed through the website [dsd.finance](https://dsd.finance). The contractions are voluntary. Users burn their tokens for coupons that promise a premium when the price returns to peg. The coupons expire if not redeemed in 30 days. - -​ -​ -## Rationale -​ -The rationale behind this change is that it fits into a larger goal of getting adoption of UMA protocol by allowing DSD’s token (DSD) to be used as collateral, where DSD’s projects with partners (such as OpenDAO) can leverage the UMA protocol. - - -​ -​ -## Implementation -​ -This change has no implementation other than adding the DSD token address to the collateral currency whitelist. - -​ -## Security Considerations -​ -Dynamic Set Dollar is designed to have cycles. During the "debt" cycle (twap<1.00) DSD may significantly lose value temporarily. As the cycles continue the amplitude of each debt cycle will minimize untill the peg of 1.00 is bootstrapped. -The other cycle of DSD is the expansion cycle, users bonded (staked) to dsd.finance and the DAO contract will be minting tokens up to 2% of the total supply every epoch. This requires a price point of $1.50 as the supply grows the expansions overtime will also be much smaller and sustainable. - diff --git a/research/uma/umips/UMIPs/umip-37.md b/research/uma/umips/UMIPs/umip-37.md deleted file mode 100644 index 8864920a..00000000 --- a/research/uma/umips/UMIPs/umip-37.md +++ /dev/null @@ -1,74 +0,0 @@ -## Headers -| UMIP-37 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add DSDUSD, USDDSD as price identifiers | -| Authors | John (dsdravage@gmail.com), Sean (sean@opendao.io) | -| Status | Approved | -| Created | January 14, 2021 | - -## Summary (2-5 sentences) -The DVM should support price requests for the DSD/USD and USD/DSD price index. - -## Motivation -The DVM currently does not support the DSDUSD or USDDSD price index. -Supporting the DSDUSD price identifier would enable the creation of the DSDO stablecoin, backed by DSD as collateral.

Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. More complex computations (like incorporating additional exchanges, calculating a TWAP or VWAP, or imposing price bands, etc.) have the potential to add a greater level of precision and robustness to the definition of this identifier, particularly at settlement of each expiring synthetic token. - -The addition of DSDUSD and USDDSD fits into a larger goal of advancing the adoption of the UMA protocol by allowing DSD to be used as collateral for minting a stable coin among a suite of [OpenDAO](https://opendao.io) stable coins. This furthers adoption of the protocol by encouraging a convergence of capital from different projects and increasing TVL. - -Currently the largest exchange with USD or stablecoin markets for DSD is [Uniswap](https://info.uniswap.org/pair/0x66e33d2605c5fb25ebb7cd7528e7997b0afa55e8) (~90% volume). If liquidity is withdrawn too fast there may be a risk in the price peg, and therefore the integrity of the system. - -In the current setting, there will need to be a significant event that erodes confidence in DSD and the token, at the same time where Uniswap liquidity is withdrawn too quickly en masse. However this may pose a security issue depending on the depth of DSDUSD liquidity on Uniswap. This may be improved by listing on additional exchanges with genuine volume. -Over time, as liquidity in the DSD token migrates across platforms, this identifier can be re-defined to add exchanges, remove exchanges, or change the way that the price is calculated. Any re-definition would be done via off-chain social consensus by $UMA-holders, and ultimately reflected in the way that $UMA-holders vote upon the price of DSDUSD and USDDSD when called to do so by disputers, or at settlement. - - - -## Implementation - -The value of this identifier for a given timestamp should be determined by querying the price from DSDUSDC pair https://info.uniswap.org/pair/0x66e33d2605c5fb25ebb7cd7528e7997b0afa55e8 on Uniswap for that timestamp. Most of the DSD trading volume happens on Uniswap, which forms the broad market consensus. -While it's important for tokenholders to have redundancy in their sources, bots and users that interact with the system in realtime need fast sources of price information. In these cases, it can be assumed that the price on Uniswap is accurate enough. - -Dynamic Set Dollar will provide the live price feed on the website publicly, and may offer API access in the future. - -## Security considerations -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-38.md b/research/uma/umips/UMIPs/umip-38.md deleted file mode 100644 index cacf723d..00000000 --- a/research/uma/umips/UMIPs/umip-38.md +++ /dev/null @@ -1,245 +0,0 @@ -# Disclaimer - -These price identifiers have been deprecated.

The reference UMA liquidator bot implementation already has a two-hour TWAP Uniswap implementation. - -Post Cutoff Cost: Calculating an aggregated statistic of compound USDC borrow rates on a confirmed range of blocks on the Ethereum blockchain is easy. All of the needed data can be computed from event logs on any Ethereum full node. An archive node allows direct querying of this data via contract methods. Additionally, this data can be accessed through querying the Compound Subgraph on the Graph Protocol, then running a simple aggregation function. - -Opportunity: The usage of a two-hour TWAP for liquidations, then an aggregated price at expiration is similar to UMIP-22. This setup allows us to create futures. Compound USDC Borrow APR futures can help borrowers and traders hedge against interest rate volatility allowing them to "lock-in" future costs from Compound loans. This will enable taking multi-collateral backed loans out on Compound for new use cases. Other users may wish to speculate on the demand for borrowing USDC on Compound for a specific month in the future. Others may simply wish to hedge their deposit interest rate volatility. Providing a price feed for the settlement of a financial contract is a prerequisite. - -Example Synthetic: `CAR-USDC-FEB28` will be a token that settles to the total annualized interest rate of borrowing USDC on Compound for (roughly) the month of February. - -Example user: A trader takes out a large loan from Compound and the current APR is 10%. Compound APRs are volatile, however, the trader wishes to lock-in this APR for the next month. The trader can buy synthetic tokens tracking this price index. If APRs increase, the trader owes more interest on their loan, but their synthetic increases in value enough to cover the cost of the increased interest. - -## Markets & Data sources - -### Pre Cutoff -This price should be queried from the highest volume Uniswap pool (Whichever one is deemed more legitimate by the UMA token holders) on Ethereum where at least one asset in the pair is CAR. It's expected that a single Uniswap pool will have 99% of the liquidity and volume so confusion will not arise. - -### Post Cutoff - -The source of truth for this data is the Compound USDC cToken's (cUSDC) `borrowRatePerBlock()` method. As of the writing of this UMIP, the agreed-upon cUSDC smart contract address is `0x39aa39c021dfbae8fac545936693ac917d5e7563`. This price identifier aggregates the value returned by `borrowRatePerBlock()` over every block from the 30 days ending at the cutoff/expiration timestamp (`1614470400` for `COMPUSDC-APR-FEB28/USDC` and `1616889600` for `COMPUSDC-APR-MAR28/USDC`). - -It is recommended to gather the raw data from an Ethereum archive node. Alternatively, this data is indexed in the [Graph Protocol](https://thegraph.com/explorer/subgraph/graphprotocol/compound-v2). As of writing this UMIP, Graph Protocol is free. However, they have plans to start charging for access in the future. In the future, querying 30 days worth of blocks may cost up to $20 USD. This UMIP's price identifier will only be used for the DVM to return the synthetic token's expiration price. Therefore, this high price won't be incurred by liquidator bots. - -Raw data is also available for download at the [Tendies Exchange public endpoint](https://cache.tendies.exchange/borrow_rate_per_block.json). This endpoint is updated with every new block but delayed by 20 block confirmations. This endpoint is free to use. To generate a similar file, governors can use and/or modify this [open source indexer script](https://github.com/evanmays/tendies-exchange/tree/master/indexer). - -All of these endpoints give the borrow rate per block for historical blocks, however converting this data to APR (and aggregation) is still required. (Read the implementation section) - -## Price Feed Implementation -### Pre Cutoff -This price should be updated every second by using the time-weighted average price from the past 2 hours. Data can be queried from Uniswap event logs on any Ethereum full node. - -Liquidator bots with access to an Ethereum full node can use this [Uniswap implementation](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) for free to query current and historical data. - -### Post Cutoff - -The intention is that the aggregated APR won't be used for liquidations. This is because the DVM only switches to this price at the CAR token expiration. By the time this aggregated statistic will be used (at expiration), liquidations won't be possible anymore. Therefore, a price feed isn't required for liquidator bots to track this rolling APR. All liquidations will use a two-hour TWAP price feed.

This is only required for the post-cutoff price. - -**8. Pricing Interval** - Per block - -**9. Dispute timestamp rounding** Round down (previous timestamp) - -## Rationale - -### Pre-cutoff - -Due to the lack of ambiguity on calculating the TWAP, UMA token holders should all converge on the same price. However, to be consistent with post-cutoff rounding, we will round pre-cutoff to 2 decimal places. - -We use the time-weighted average price (TWAP) as opposed to the average price at the end of each block. This causes collateralization requirements to be more accurate as block times are highly variable. - -Most volume is expected to be on the Uniswap USDC/CAR pools. - -Further rationale for using a two-hour TWAP is in the UMIP-22 Rationale section. - -### Post-cutoff - -We're using a rolling 30 day period to increase the cost of manipulating the APR price. - -We use geometric mean, as opposed to arithmetic mean, to include the effect of interest compounding. - -We use an annual percentage rate, as opposed to a monthly percentage rate, to increase usability. 1) Annual rates are large enough numbers that, combined with an easy to understand 1-to-1 APR to USDC ratio, result in prices (most of the time) in the range of $1 to $30. 2) Annual rates are more commonly used when discussing loan borrowing rates. - -For clarification, here's an example of the 1-to-1 conversion. 7% APR is $7USDC and 3% APR is $3USDC. - -There is a ground-truth for this price identifier. The ground truth data is in the Compound smart contract on the Ethereum blockchain. Any differences in UMA governor results for this price identifier should be due to rounding errors that propagate through the calculation (numerical instability) as opposed to multiple data sources being the truth (as is the case with looking at the price of bitcoin on different exchanges). - -We mitigate the effects of numerical instability by rounding to the nearest two decimal places. Different algorithms for calculating the geometric mean result in tiny differences in the result. Rounding to 2 decimal places hides small differences in geometric mean calculations. For example, if person A calculates the price request result as $7.53453USDC and person B calculates the price request result as $7.53489USDC, both will agree on $7.53USDC. - -## Implementation - -### Pre-cutoff - -For price requests made before the cutoff, (`1614470400` for `COMPUSDC-APR-FEB28/USDC` and `1616889600` for `COMPUSDC-APR-MAR28/USDC`), use the same two-hour TWAP calculation implementation from UMIP-22. - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the USDC/CAR pool returns at the end of the latest block whose timestamp is <= the timestamp that is queried for. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. As the token price will already implicitly be tracking the COMPUSDC-APR-TWAP-OR-30DAY-FEB28/USDC or COMPUSDC-APR-TWAP-OR-30DAY-MAR28/USDC price, it should be left as returned without any scaling transformation. -6. The final price should be returned with the synthetic token as the denominator of the price pair and should be submitted with 6 decimals. But rounded to 2 decimal places. For example, if the APR is 7.38482747%, then we round to 2 decimal places and convert 1-to-1 to USDC for $7.38USDC. However, USDC on Ethereum uses 6 decimal places so voters must submit $7.380000USDC. - -### Post-cutoff - -For price requests made after or on the cutoff, (`1614470400` for `COMPUSDC-APR-FEB28/USDC` and `1616889600` for `COMPUSDC-APR-MAR28/USDC`), use the below geometric mean calculation. - -This implementation works with the dataset from [Tendies Exchange public endpoint](https://cache.tendies.exchange/borrow_rate_per_block.json). To use it with other datasets, modify the `getBorrowRatePerBlock()` function. This implementation is updated as an [open source price feed script](https://github.com/evanmays/tendies-exchange/tree/master/indexer). - -The script below expects a `start_block` and `end_block` for the 30 day period. UMA token holders should define these as follows. -``` -start_block = The block the DVM Timestamp was mined in -start_timestamp = DVM Timestamp - 30 days -end_block = The block mined most recently after start_timestamp -``` - -These values can be put into this script. The script also expects `expected_blocks_per_year`.

The trading price of CAR is the expected aggregate compound interest rate at the end of February and March. This is slow moving by default, so price manipulation if the two-hour TWAP should be challenging. However, the price may be volatile during earlier periods of the month. This is due to the lack of information about the future. It is expected these prices become less volatile as the cutoff/expiration date nears. - -Anyone relying on this data point should also note that manipulating the APR for a specific block is possible for users with large amounts of capital. These users can deposit this capital into the pool, remove this capital from the pool, or take large loans against the pool to significantly change the interest rate for a block. Aggregated APRs should mitigate this type of manipulation. diff --git a/research/uma/umips/UMIPs/umip-39.md b/research/uma/umips/UMIPs/umip-39.md deleted file mode 100644 index 1a7c2445..00000000 --- a/research/uma/umips/UMIPs/umip-39.md +++ /dev/null @@ -1,308 +0,0 @@ -## HEADERS -| UMIP-39 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add USD/bBadger and USD-[bwBTC/ETH SLP] as supported price identifiers | -| Authors | mitche50, J au Defi, bitcoinpalmer, Defi Frog, Sean Brown (smb2796) -| Status | Approved | -| Created | 1/15/2021 - - -# SUMMARY - -The DVM should support price requests for the below price indexes: -- USD/bBadger -- USD-[bwBTC/ETH SLP] - -# MOTIVATION - -The DVM currently does not support the USD-[bwBTC/ETH SLP], USD/bBadger price identifiers. - -BadgerDAO’s first product is Sett vault, an automated DeFi aggregator focused on tokenized BTC assets.

Currently, only low volume and low depth centralized exchanges have Badger listed, and most liquidity will remain on DEXs as it is incentivized. - -**What analysis can you provide on where to get the most robust prices? (Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges)** - -Sushiswap and Uniswap have the vast majority of Badger volume and depth. These should be used over all other sources. - -**What is the potential for the price to be manipulated on the chosen exchanges?** - -Badger is not a collateral on any loan services and the majority of the liquidity is locked into farming vaults / geysers. The potential risk for this is low. - -**Should the prices have any processing (e.g., TWAP)?** - -Processing is defined in the implementation section. - -# IMPLEMENTATION - -B wrapped tokens have 2 components to finding the underlying value of the tokens associated with them. Each wrapped token has a pricePerFullShare, which is the amount of underlying tokens that 1 b token could be redeemed for through the withdraw function. This underlying token can have different ways to determine its value depending on what type of token it is. - -The price per full share can be found by querying the contract of the token with `getPricePerFullShare` as seen in method 9 on this [contract](https://etherscan.io/address/0x19D97D8fA813EE2f51aD4B4e04EA08bAf4DFfC28#readProxyContract). - -getPricePerFullShare is a pure view logic function in which no one has any authority to manipulate: - -``` -if (totalSupply() == 0) -{ - return 1e18; -} -return balance().mul(1e18).div(totalSupply()); -``` - -This returns the value of the balance of the vault divided by the number of shares to give the user the value of 1 share of the vault token. balance() represents the total balance of the underlying token in the vault. For example, if a user has 1 bBadger, this could be worth 1.2 Badger (which would be the ratio of balance / totalSupply). - -For bBadger you could use the same getPricePerFullShare method (described above) from the contract to get the underlying amount, and then the underlying values can be queried to give the price of one bBadger token in USD. - -For both implemenations, a block number will need to be used. The block number should be the block that is closest to and before the timestamp that the price request timestamp. - -## Determining the WBTC/USD price - -For both of these price identifiers, the WBTC/USD price will need to be used in the pricing calculation. - -To obtain the WBTC/USD price, follow this process.

However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. - -Although these are "wrapped" tokens, an objective value of the underlying collateral can be accurately determined to adequately inform both participating liquidators and disputers. - -The value of collateral can be objective in terms of price per full share * underlying asset value. - -If the vault was hacked in a way that drained funds, the price per full share would decrease in a way that makes the collateral "proportionally recoverable" for all users. There is also insurance from Nexus mutual to consider in terms of valuing the asset in the event of a covered vulnerability - -For context, the wrapping mechanism mints a token that represents a % share of a liquidity pool or vault. This is common practice when providing liquidity to an AMM or depositing into a yield optimizer. Using identifiers like price per full share, an oracle can deterministically calculate the value of what the unwrapped ERC20 tokens would be worth at any given time. - -Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. $UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. diff --git a/research/uma/umips/UMIPs/umip-4.md b/research/uma/umips/UMIPs/umip-4.md deleted file mode 100644 index 7bc4c598..00000000 --- a/research/uma/umips/UMIPs/umip-4.md +++ /dev/null @@ -1,186 +0,0 @@ -# Headers -| UMIP-4 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Register new financial contract with DVM | -| Authors | Matt Rice (matt@umaproject.org), Prasad Tare (prasad@umaproject.org), Chris Maree (chris@umaproject.org), Nick Pai (nick@umaproject.org) | -| Status | Approved 19 May 2020 | -| Created | April 30, 2020 | - - -# Summary - -This UMIP provisionally registers the `ExpiringMultiParty` template with the DVM. -This financial contract template enables the creation of priceless synthetic tokens, as described [here](https://docs.umaproject.org/uma/synthetic_tokens/explainer.html). - -Synthetic tokens are collateral-backed tokens whose value fluctuates depending on the tokens’ reference index. -The proposed contract design has the following features: -- Contract parameters can be customized by the initial deployer -- Anyone can mint synthetic tokens by depositing Dai as collateral -- Anyone can liquidate undercollateralized positions -- Anyone can dispute invalid liquidations within a 2-hour liveness period -- Disputes will be resolved by the DVM, and the contract otherwise does not require an on-chain price feed - -# Motivation - -Up until now, other synthetic token designs have required the smart contract to know the value of the collateral at -all times, as reported by an on-chain price feed. This is a problem because on-chain oracles are costly to maintain -from a gas and DevOps perspective and leaves contracts open to price-feed manipulation attacks. “Priceless” synthetic -tokens differ because they do not require an on-chain price feed to indicate whether the contract is properly collateralized. -Instead, they have a liquidation mechanism that allows anyone to liquidate an undercollateralized position. They can -do so by providing rewards to counterparties or third parties for identifying improperly collateralized positions. -To confirm that these positions are improperly collateralized, these contracts may rely on a “Data Verification -Mechanism” (DVM). This makes the proposed design more decentralized and resilient against manipulation. - -This is the first “priceless” financial contract template to be registered with the DVM. - -# Technical Specification - -“Priceless” synthetic tokens are synthetic tokens that are securely collateralized without an on-chain price feed. -These tokens are designed with mechanisms to incentivize token sponsors (those who create synthetic tokens) to properly -collateralize their positions. These mechanisms include a liquidation and dispute process that allows token holders to be -rewarded for identifying improperly collateralized token sponsor positions. The dispute process relies on an oracle, -the UMA DVM, to settle disputes regarding liquidations. - -A deployment of a priceless synthetic token is defined by the following parameters. The contract template that is -registered with the UMA DVM will hardcode or restrict some of these parameters, as indicated below. All other -parameters can be customized in individual deployments of the contract. - -- expirationTimestamp: These are discretized to monthly expires on the 1st day of each month at 12:00:00 UTC. The max timestamp is June 30, 2021. -- collateralAddress: DAI (0x6b175474e89094c44da98b954eedeac495271d0f). To register additional collateral currencies (e.g. USDC), a new factory contract that has the USDC address in the collateralAddress line would need to be registered and approved by $UMA-holders. To stop supporting DAI, this factory and any other factory with DAI as the collateralAddress would have to be de-registered by $UMA-holder vote. -- priceFeedIdentifier -- syntheticName -- syntheticSymbol -- collateralRequirement -- disputeBondPct -- sponsorDisputeRewardPct -- disputerDisputeRewardPct -- minSponsorTokens -- timerAddress: Hardcoded to 0x0000000000000000000000000000000000000000 -- withdrawalLiveness: Hardcoded to 120 min. -- liquidationLiveness: Hardcoded to 120 min. - -Since this is the first token factory that proposes using Dai as the collateralAddress, this proposal also includes -initializing the finalFees for Dai to 10 Dai for all contracts that use Dai as the collateral currency. The finalFee -parameter is an adjustable DVM parameter controlled by $UMA holders to establish a minimum fee for each price request -that a contract makes. It is intended to introduce a cost to prevent malicious users from spamming the DVM and overloading -it with price requests, but not be so high as to deter disputers from performing their work. - -In proposing that Dai is used as the collateral currency for the synthetic token factory, factors were considered -including: smart contract security, broad usability and acceptability, and on-chain liquidity. These factors are -important because the value of Dai will be used by $UMA-holders to determine the amount of PfC, or profit-from-corruption, -that exists in the UMA ecosystem; therefore $UMA-holders must be able to objectively determine the valuation of Dai. -Additionally, token contracts deployed from this factory will pay fees in Dai to the DVM Store, which will be used to -buy-and-burn $UMA tokens; therefore, Dai liquidity is an important consideration in the approval process. - -## Launching a New Synthetic Token - -To launch a new type of synthetic token for which an existing market does not yet exist, that synthetic token’s smart -contract must first be parameterized and deployed. Anyone (a “Contract Deployer”) can parameterize and deploy this contract. -After the contract is deployed, anyone (“Token Sponsors”) can interact with the contract to create synthetic tokens. - -Token Sponsors deposit collateral into the contract to collateralize synthetic tokens, which they can then withdraw -and trade with others. The first token sponsor to create synthetic tokens is able to immediately withdraw synthetic tokens -from the contract. Any following token sponsors must collateralize their positions by at least as much as the system’s -average collateralization ratio among all token sponsor positions that have not been liquidated (“GCR," or global -collateralization ratio). Requiring new token sponsors to collateralize their positions by as much as the GCR provides -some assurances that so long as those token sponsors collateralized below the GCR have not yet been liquidated, those -above the GCR need not be at risk of liquidation. - -## Managing Token Sponsor Positions - -Token sponsors can deposit additional collateral at any time. Token sponsors can withdraw excess collateral in one of two ways: a “fast” withdrawal or “slow” withdrawal. - -### “Fast” withdrawal: - -A “fast” withdrawal allows a token sponsor to withdraw excess collateral from his position immediately, so long as the resulting position is collateralized by at least as much as the global collateralization ratio (GCR). -Requiring withdrawals to result in collateralization at least as high as the GCR provides some assurances that so long as the other token sponsors collateralized below the GCR have not yet been liquidated, this token sponsor should not be liquidated after making this withdrawal. - -### “Slow” withdrawal: - -If the token sponsor wishes to withdraw collateral from his position that would bring his collateralization below the -global collateralization ratio, he can do so via a “slow” withdrawal. Because withdrawing this amount of collateral -could potentially jeopardize the solvency of the fungible synthetic tokens, this “slow”, 2-part, withdrawal process -allows other token holders to flag if a withdrawal would render the token sponsor insolvent. - -In a “slow” withdrawal, there are two parts: The token sponsor submits a withdrawal request to the contract indicating the amount of collateral he wishes to withdraw and the timestamp of the request. - -During this period, any token holder can liquidate the token sponsor’s position if they believe a withdrawal of the amount -indicated in the withdrawal request would bring the token sponsor’s collateralization below the “collateralization -requirement” at the time of liquidation. If the “withdrawal liveness period” of 2 hours passes without a token holder -liquidating the token sponsor, the token sponsor may withdraw collateral from his position up to the amount requested. - -## Liquidation and Dispute - -At any time, a token holder may liquidate a token sponsor’s position. Liquidations happen immediately without calling -the oracle. Anyone may dispute a liquidation within the “liquidation liveness period” of 2 hours. - -To liquidate a token sponsor position, a token holder submits tokens to the contract and posts a liquidation bond. -The liquidation bond covers the cost of calling the DVM if the liquidation is disputed. -If the liquidation is not disputed, the liquidation bond is returned to the liquidator. -The tokens are submitted for 3 purposes: to indicate the size of the position to be liquidated, to close the token sponsor’s position, and to attest to the liquidator’s belief that the token sponsor’s position should be liquidated. -The liquidator will lose a portion of the collateral corresponding to the tokens if their liquidation is disputed and found to be invalid. - -Here are three ways in which a liquidation can be resolved: - -1. No one disputes the liquidation during the liquidation liveness period. -After the liquidation liveness period ends, collateral deposited by the token sponsor is returned to the liquidator, proportional to the number of synthetic tokens the liquidator has submitted in liquidation. - -2. Someone disputes the liquidation during the liquidation liveness period. -To do this, the disputer must post a bond. Once the dispute is raised, a price request is made to the UMA DVM. -This price request will return the value of the price identifier at the time of the liquidation, which will determine if the token sponsor was undercollateralized and resolve the "dispute". - -2a. If the price returned by the DVM indicates that the token sponsor was undercollateralized at the time of the liquidation: -- The disputer will lose their bond. -- The liquidator will receive all of the token sponsor position’s collateral. -- The token sponsor will not receive any of the collateral they have previously deposited into the position. - -2b. If the price returned by the DVM indicates that the token sponsor was not undercollateralized at the time of the liquidation: -- The disputer will receive back their dispute bond and a dispute reward. -- The liquidator will receive collateral equalling: (i) the value of the token at the time of liquidation as determined by the DVM, less (ii) the dispute reward paid to the disputer, less (iii) the improper liquidation reward paid to the original token sponsor. -- The token sponsor will receive any remaining collateral and a reward for the improper liquidation. - -## Redeeming Tokens - -Before the expiration date of the token, tokens may only be redeemed by token sponsors. -A token sponsor redeems a token by submitting it to the contract to be burned and receiving collateral proportional to the total amount of collateral that the token sponsor has deposited to the contract. - -## Redeeming After Expiry - -After the expiration timestamp for the synthetic tokens, anyone may settle the contract. -This calls on the UMA DVM to return the value of the token’s price identifier at the expiration timestamp. - -After this value is returned to the contract and the contract is settled, any token holder can redeem the tokens against the contract. -Redemption of the tokens returns the token holder collateral equal to the price identifier value returned by the UMA DVM. Sponsors may also withdraw any excess collateral from the contract after settlement. - -Additional details can be found [here](https://docs.umaproject.org/uma/synthetic_tokens/explainer.html). - -# Rationale - -Please see the individual PRs for the rationale behind each PR. - -# Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/core/contracts/financial-templates/implementation). -The directory contains both the [implementation](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/implementation/ExpiringMultiParty.sol) of the `ExpiringMultiParty` template and the [deployer contract](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/implementation/ExpiringMultiPartyCreator.sol) that will be registered with the DVM to allow users to deploy their own `ExpiringMultiParty` contract. - -# Security considerations - -Please see the individual PRs for details on how each affects the security of the UMA ecosystem. This repo has been audited by OpenZeppelin, and the final audit report will be made available [here](https://docs.umaproject.org/uma/index.html). - -Anyone deploying a new priceless token contract should take care to parameterize the contract appropriately to avoid the -loss of funds for users. Additionally, the contract deployer should ensure that there is a network of liquidators and -disputers ready to perform the services necessary to keep the contract solvent.

What are the financial positions enabled by creating this synthetic that do not already exist? - - Currently there does not exist an on-chain product on Ethereum that enables folks to deploy risk capital on the futures term structure on either BTC or ETH. Basis (difference between futures and spot) is a heavily popular product suite in the CeFi ecosystem that has nearly ~300mil+ ADV (average _daily_ volume) in this regime allocated to it, and with the rise of interest rate products on-chain, basis synthetics would be heavily useful for folks speculating on the steepening or flattening of the interest rate curve for BTC and ETH. - -2. Please provide an example of a person interacting with a contract that uses this price identifier. - - If Alice thought that the term structure on BTC or ETH was rich, then she could sell ("flattener") BTC/ETH-BASIS-3M/6M on AMM pools that it exists on. If Alice thought that the term structure on BTC or ETH was cheap, then should buy ("steepener") BTC/ETH-BASIS-3M/6M on AMM pools that it exists on. If Bob thought that there's a contentious ETH fork that'd split hash appropriately and give value to both forks, then a short-basis positions would create an accretive value position for Bob as the utility of the spot would outpace the futures (depending on how CeFi exchanges resolved indices, but usually they pick a fork), and in this case could sell ETH-BASIS-3M/6M. If Bob thought that the 3m-6m basis is rich or cheap, then he could buy or sell a combination of 3m and 6m synths appropriately. Essentially, folks can express a supply/demand crunch for BTC or ETH in terms of the basis. - -3. Consider adding market data - -While there does not exist a liquid proxy for basis, one could attribute the absence of the ~40%+ APY on the front end of the curve prevalent in alt futures in '17/'18 to the rise of the hedgers / speculators on basis in '19/'20, where the monthly volumes on basis portfolios vastly exceeds most TVLs of any DeFi product. - -# MARKETS & DATA SOURCES - - **Required questions** - -1.

- -# RATIONALE - -- Why this implementation of the identifier as opposed to other implementation designs? - -This question can be answered three-fold: 1) the choice of BTC and ETH for the basis was chosen as they are currently the two highest market cap coins with the most liquid futures markets. In the future, we plan to add others as well. 2) the maturity of the basis was chosen to be the two closest maturities (3m - March and 6m- June) as they are the most liquid / highest ADV 3) the choice of the 3 exchanges is explained below, but essentially they are 3 out of the 4 top exchanges globally for ADV/liquidity/reputation. - -- What is the reasoning for min + max bounds on the px identifier? - -Per some of the feedback, CeFi exchanges already have clamps around their swap funding rates to mitigate a persistent dislocation, and based on empirical analysis the +-25% bounds on the basis for both BTC and ETH seemed more than generous, and adds to the economic security around the synthetics to ensure sponsors do not get liquidated in a way that is not consistent with the term structure itself. - -- What analysis can you provide on where to get the most robust prices? (Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges) - -As mentioned in the initial section, Binance, Okex, and FTX are 3 out of the 4 most liquid / highest ADV exchanges in the world for derivatives and spot markets and reputed to be of extremely high quality with low probability of the exchange defaulting. The last few months, Binance regularly has had higher than 20 bil ADV, Okex >10bil, and FTX > 2bil. The wide consensus is that the BTC futures, ETH futures, BTC spot, and ETH spot are of the highest legitimate liquidity/volume + minimal price discrepancies from other exchanges. - -- What is the potential for the price to be manipulated on the chosen exchanges? - -Extremely low. Even to move the BTC or ETH spot/futures markets a percent, it'd require more than a few dozen million given the efficiency of the liquidity provision on these exchanges. Even in cascading liquidations on the future market, the basis has historically held up strongly given the liquidity on the spot and futures markets. - -- Should the prices have any processing (e.g., TWAP)? - -Not required to have a TWAP/VWAP/etc. - -

Human intervention in extreme circumstances where the result differs from broad market consensus. - -4. **Result processing** - - For BTC futures prices, the median of the prices from the 3 exchanges should be used. For BTC spot prices, the median of the prices from the 3 spot exchanges should be used. Same for ETH. - - As an example, for BTC-BASIS-3M, the formula is min(max(100.0 * [1 + (F-S)/S], 75.0), 125.0), where F would be a median of the 3 futures prices as mentioned above and S would be a median as well of the 3 spot prices, and the result would be rounded to 6 decimals. - -
- -# Security considerations - -**Example questions** - -1. Where could manipulation occur? - -As discussed in the `What is the potential for the price to be manipulated on the chosen exchanges?`, manipulation could occur at either at the spot layer or the futures layer on each of the each of the aforementioned exchanges. To disrupt BTC or ETH spot of futures on the biggest exchanges globally would require capital at the highest scale, and the dislocation, were it to be caused, would be short-dated due to the efficiency of those markets. - -Further, towards expiration, the front-month futures will become less liquid and easier to manipulate in terms of required capital. As such, we will ensure that the expiration of the synths using these price identifiers will expire a week _before_ any of the constituent futures in the basket expire. This way, we will minimize this attack vector. - -Lastly, as a form of manipulation resistance, per some of the feedback, CeFi exchanges already have clamps around their swap funding rates to mitigate a persistent dislocation, and based on empirical analysis the +-25% bounds on the basis for both BTC and ETH seemed more than generous, and adds to the economic security around the synthetics to ensure sponsors do not get liquidated in a way that is not consistent with the term structure itself. - -2. How could this price ID be exploited? - -Mentioned above. - -3. Do the instructions for determining the price provide people with enough certainty? - -Yes. - -4. What are current or future concern possibilities with the way the price identifier is defined? - -When the 3m and 6m expire, we'd have to recreate another set of price identifiers to encode maturity into the price identifier. However, when I spoke to Matt recently, I understand that there are upcoming DVM upgrades that'd enable passing in additional state so as to not create price identifier bloat, or in this case, recreating one every time there is a new future. - -5. Are there any concerns around if the price identifier implementation is deterministic? - -No. diff --git a/research/uma/umips/UMIPs/umip-41.md b/research/uma/umips/UMIPs/umip-41.md deleted file mode 100644 index c19b6605..00000000 --- a/research/uma/umips/UMIPs/umip-41.md +++ /dev/null @@ -1,105 +0,0 @@ -## Headers -| UMIP 41 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add uVOL-BTC-APR21 as a price identifier | -| Authors | Sean Brown (smb2796), Kevin Chan (kevin-uma), Tom Ibold (Tommy1231232) | -| Status | Approved | -| Created | January 25, 2021 -| [Discourse Link](https://discourse.umaproject.org/t/adding-volbtc-as-a-price-identifier/83 ) | - -## SUMMARY - -The DVM should support price requests for the 30-day daily volatility of BTC/USD. - -## MOTIVATION - -The DVM currently does not support the 30-day day volatility of BTC/USD. - -The volatility of Bitcoin is a major focus in the crypto and traditional finance world. Will the recent high volatility in Bitcoin continue throughout the year? Is Bitcoin too volatile to be considered a viable currency or safe haven asset? Whether volatility is considered high or low or where it will be in the future is always a debate. - -In traditional finance there are several ways to express your view on the volatility of an asset. Most options traders would reflect this opinion on an asset by buying or selling options and delta hedging. This effectively neutralizes the price movement of the asset and isolates the value of the option. However, for an average trader this may be complex, costly and requires a lot of maintenance of the position. An easier way to reflect this view is through a futures contract on a volatility index. The most popular index is the VIX which is a volatility index on the S&P 500 that derives its value from a basket of index options. The centralized exchanges in the crypto world are borrowing this concept to create similar ways for users to trade the volatility of Bitcoin. For example, FTX designed BVOL tokens which use a basket of their MOVE contracts to effectively create a volatility index in a similar way. This requires a consistently deep and liquid options market which proves to be a challenge in crypto especially in the decentralized finance space. - -With the uVOL-BTC price identifier we can create a simple volatility index that can be used to create tokens with the EMP contract to speculate on the volatility of BTC/USD in a decentralized way. - -## MARKETS & DATA SOURCES - -- Markets: Binance, Coinbase Pro, Bitstamp -- Pairs: BTC/USD for Coinbase Pro and Bitstamp, BTC/USDT for Binance -- Live Price Endpoints - -Not applicable for the volatility data given that it only needs to be calculated at expiry using the historical endpoints listed below. - -Uniswap data is on-chain and can easily be queried in real-time.

No. -- If there is a free tier available, how many queries does it allow for? Range of 20,000-30,000. -- What would be the cost of sending 15,000 queries? Covered by the initial free tier allowance, but ~$5 after that has been used. - -## PRICE FEED IMPLEMENTATION -For the creation of a BTC/USD volatility token, it is desired that the DVM return either the 30-day daily realized volatility of BTC/USD, or a 2-hour TWAP on the market price of uVOL-BTC. The type of price that the DVM will return is dependent on the timestamp the price request is made at. `1619827200` is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the 30-day daily realized volatility of BTC/USD calculation is used at expiry. This is very similar to the uGAS token and this design is outlined in [UMIP 22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md). - -This means that only the Uniswap TWAP calculation will need to be queried in real-time. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. - -## TECHNICAL SPECIFICATIONS -- Price Identifier Name: uVOL-BTC-APR21 -- Base Currency: uVOL-BTC-APR21 -- Quote currency: None. This is an index, but will be used with USDC. -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE -The uVOL-BTC token is an expiring token that settles at the end of a month with the prior 30-day realized daily volatility in annualized terms. This is different from centralized and traditional volatility indices that use implied volatility of options and prices of other options like securities to derive an index of expected volatility. The use of realized volatility in this design is very similar to a [volatility swap](https://www.investopedia.com/terms/v/volatilityswap.asp) in traditional finance. We believe this will be a simple and transparent way for crypto users to trade the volatility of an asset like Bitcoin in a decentralized way. UMA token holders can easily calculate or verify the settlement price by using just their browser and a spreadsheet. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because a synthetic token, that is trading based on the future price of an underlying index, will have its price affected by expectations of the future movement of the underlying. If there is a large discrepancy in the synthetic’s price and the underlying index, arbitrageurs could take advantage of the difference in price by minting tokens at a rate determined by the underlying, abandoning their collateral to be liquidated and selling the tokens at the higher trading rate. Additionally, if a token is trading at a price that is higher than the notional value of the backing collateral, there would be no economic incentive for a liquidator to perform a liquidation. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -## IMPLEMENTATION -Voters should determine which pricing implementation to use depending on when the price request was submitted. - -**At Expiry** -If the price request's UTC timestamp is at or after 1619827200 (May 1, 2021 @ 12:00AM UTC), a price request uVOL-BTC for a given timestamp should be determined by performing the below for each data source (Coinbase Pro, Binance and Bitstamp): -1. Query the daily price of BTC/USD(T) over the previous 31 days before the given timestamp (1619827200) from each market. This can be queried for each day using the historical endpoints provided. -2. Calculate the percentage change between each day over the 30-day time period independently for each market. The daily percentage change is calculated in this way: [Close Price/Open Price - 1]. -3. Take the standard deviation of this 30 observation data set. This can be done using a spreadsheet function such as [STDEV](https://support.google.com/docs/answer/3094054?hl=en) in Google Sheets or one can manually [calculate](https://www.investopedia.com/terms/s/standarddeviation.asp) this. The result is the standard deviation of a daily move and should be done independently for each market. -4. Multiply each market's standard deviation by the square root of 365 to annualize the result. -5. Finally, multiply the three results by 100 to produce the index value. -6. Take the median of the Coinbase Pro, Binance and Bitstamp results from step 5. -7. Round the median to 6 decimal places. - -An example of a hypothetical uVOL-BTC-DEC20 settle is illustrated in [this](https://docs.google.com/spreadsheets/d/1PJDithMqoCY4Y5ANPw0KPW6q8kPj2O62L8gflCkZ2OA/edit#gid=599037359) Google Sheet. - -**Before Expiry** -If the price request's UTC timestamp is less than 1619827200 (May 1, 2021 @ 12:00AM UTC), voters will need to calculate a 2-hour TWAP for the uVOL-BTC-APR21 token's price in USDC. The following process should be used to calculate the TWAP. -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the uVOL-BTC-APR21 / USDC pool returns in the latest block where the block timestamp is <= the price request timestamp. This is the price of 1 uVOL-BTC-APR21 token in USDC. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. This should then be rounded to 6 decimals. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -## Security Considerations -Security considerations are focused on the use of the token price for monitoring collateral ratios. -- Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -- Mismatch between TWAP and gap higher in token price - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations - as the 30-day realized daily volatility of BTC/USD should be slow moving by design - or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uVOL-BTC, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -Security considerations, like the ones above, have been contemplated and addressed, but there is potential for security holes to emerge due to the novelty of this price identifier. - -Additionally, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Contract deployers should also ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier or editing its implementation if security holes are identified. diff --git a/research/uma/umips/UMIPs/umip-42.md b/research/uma/umips/UMIPs/umip-42.md deleted file mode 100644 index 5cae8ad0..00000000 --- a/research/uma/umips/UMIPs/umip-42.md +++ /dev/null @@ -1,41 +0,0 @@ -## Headers -| UMIP-42 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add renDOGE as a collateral currency | -| Authors | Logan Fulcher (logan@opendao.io) | -| Status | Approved | -| Created | January 20,2021 | -| Link to Discourse | https://discourse.umaproject.org/t/adding-rendoge-as-collateral-umip/24/30 | - -## Summary (2-5 sentences) -This UMIP should add renDOGE to the supported collateral currencies into the global whitelist contract, allowing for the usage of renDOGE as collateral currency. - -## Motivation -Dogecoin is a derivative of Luckycoin which forked from Litecoin and uses a Scrypt algorithm. It has been a presence in the crypto currency community since 2013, and despite its reputation as "only a meme coin," dogecoin sees ongoing mining and significant trade volume, particularly among the Litecoin mining community and its highly dedicated meme fan base. DOGE has a current market capitalization of $1.17 billion & 24 hour trading volume of approximately $256 million. The coin has maintained a top 100 position in market cap for nearly 8 years. - -renDOGE is an ERC20 variant of DOGE and is the catalyst for the process of incorporating DOGE into decentralized finance. renDOGE is similar to renBTC, in that the DOGE is custodied in a permissionless manner by Ren. Thus, it is a straightforward process to move between DOGE and renDOGE. - -The motivation for adding renDOGE as a supported collateral in the global whitelist contract is for providing DOGE holders an opportunity to go long on DOGE - bringing it onto the Ethereum blockchain makes this possible. The process utilizes RenVM via OpenDAO to convert DOGE to renDOGE, then mint a stablecoin backed by DOGE ($DOGEO) as collateral, which is built on UMA. - -In process, renDOGE holders would supply tokens to the OpenDAO Platform as a collateral asset to mint DOGEO via underlying UMA contracts; the newly minted DOGEO, being a synthetic asset that traces the value of USD, could then be used elsewhere or converted into another stablecoin for a variety of purposes. Once users of the DOGEO token want their locked renDOGE collateral back, they would bring DOGEO back to the OpenDAO platform, settle any fees/interest, and then reclaim their renDOGE tokens which can be converted back into the original DOGE. A DOGEO/USDC pool will be created via Uniswap for easy access into other markets using DOGEO. It is also possible that DOGEO may find itself available for use in other future applications as well. - -## Technical Specification -To accomplish this upgrade, two changes need to be made: -- The renDOGE address, [0x3832d2F059E55934220881F831bE501D180671A7](https://etherscan.io/address/0x3832d2F059E55934220881F831bE501D180671A7#readProxyContract), needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 11,000 renDOGE needs to be added for the renDOGE in the Store contract. - -## Rationale -​ -The rationale behind this change is that it fits into a larger goal of furthering adoption of the UMA protocol by allowing renDOGE to be used as collateral, whereas DOGE's wide user base, which currently lacks yet shows interest in defi integration, can leverage the UMA protocol. Other projects are currently working towards this goal as well. Major community members in the DOGE community, along with commercial enterprises, have already shown interest in our efforts. UMA is the best choice for furthering this endeavor, as the security, service, team, and reputation provided by UMA are certain to make these efforts successful and secure. - -The addition of renDOGE serves UMA, OpenDAO, Ren, their respective communities and members, the Dogecoin community, and the larger crypto and defi industries at large. - -## Implementation -​ -This change has no implementation other than the changes listed in the *Technical Specification* section. - -## Security Considerations -​ -renDOGE has several security considerations that have been taken in to account and discussed at length by the UMA community (available here: https://discourse.umaproject.org/t/adding-rendoge-as-collateral-umip/24/32). Major concerns included, liquidity and its stability, unusually high volatility, and peg detachment. Since the initial submission of this umip, we have seen both the demand and the volume of renDOGE increase dramatically, and with continued growth, we expect the necessary volume and liquidity required for security to be met; SushiSwap just added the renDOGE-WETH pair to Onsen and we are seeing more projects creating utility. The token is also gravitating more tightly towards its peg, and the overall outlook for renDOGE is positive. However, due to the novelty of the renDOGE token, and the unusually high volatility of the underlying DOGE collateral, it is recommended that the collateralization factor for renDOGE be increased to 3x-5x, as deemed appopriate by UMA. Additionally, it is suggested that voting time extensions beyond the typical duration be considered to prepare for counteracting periods of low lqiuidity. - -Additionally, it is important to note that renDOGE will likely be approximately 0.1% lower in price than DOGE, due to the 0.1% fee involved with going from renDOGE to DOGE, however, we don't expect this to greatly impact security. diff --git a/research/uma/umips/UMIPs/umip-43.md b/research/uma/umips/UMIPs/umip-43.md deleted file mode 100644 index 5431ce79..00000000 --- a/research/uma/umips/UMIPs/umip-43.md +++ /dev/null @@ -1,39 +0,0 @@ -# Headers -| UMIP-43 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add Ocean as a collateral currency | -| Authors | Logan (logan@opendao.io) | -| Status | Approved | -| Created | January 28, 2021 | -| Created | January 28, 2021 | -|Link to Discourse| https://discourse.umaproject.org/t/adding-ocean-as-collateral-umip/117 | - -## Summary (2-5 sentences) -This UMIP will add Ocean to the supported collateral currencies on the global whitelist contract, allowing the usage of Ocean as collateral currency. - -## Motivation -The motivation of adding Ocean as a supported collateral in the global whitelist contract is so that Ocean holders can go long on Ocean by minting a stablecoin backed by Ocean as collateral, which will be built on UMA. - -The Ocean token is used to stake on data, to govern Ocean community funding, and to buy & sell data.

NA -- What would be the cost of sending 15,000 queries? $0. - -## PRICE FEED IMPLEMENTATION -For the creation of the uSTONKS token, it is desired that the DVM return either the final closing index value of uSTONKS, or a 2-hour TWAP on the market price of uSTONKS_APR21. The type of price that the DVM will return is dependent on the timestamp the price request is made at. This timestamp is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the closing index value of uSTONKS calculation is used at expiry. This is very similar to the uGAS token and this design is outlined in [UMIP 22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md). - -Because the uSTONKS index value is only used at expiry, it will not be possible for a token sponsor to become undercollateralized based upon its movement. This means that only the Uniswap TWAP will need to be queried in real-time with a price feed. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. - -## TECHNICAL SPECIFICATIONS -- Price Identifier Name: uSTONKS_APR21 -- Base Currency: uSTONKS_APR21 -- Quote currency: None. This is an index, but will be used with USDC. -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE -The uSTONKS token is an expiring token that settles at the end of the expiry month using the final exchange closing prices on the last business day of the month for the ten stocks in the basket. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because uSTONKS is a decentralized synthetic that trades continuously 24/7 whereas the underlying stocks in the uSTONKS index trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. Using price feeds from the exchanges to monitor collateral ratios of token sponsors could be problematic outside of market hours especially if there is significant news released or general macro market forces. Though some stocks are traded after hours, the ability to extract this price data is difficult and the frequency may not be consistent across all ten stocks. Therefore, using the uSTONKS token price itself to monitor collateral ratios is a much better alternative as it should reflect the actual price movements during exchange hours and also reflect expectations of price movements after market hours. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -The stocks chosen represent the stocks with the highest average comment volume on r/WallStreetBets. This index was picked on January 29th, 2021 using r/WallStreetBets comment analysis from swaggystocks.com, and will remain static throughout the life of the price identifier. - -## IMPLEMENTATION -Voters should determine which pricing implementation to use depending on when the price request was submitted. - -**At Expiry** - -If the price request's UTC timestamp is at 1619812800 (April 30, 2021 @ 4:00PM EST), a price request for uSTONKS for a given timestamp should be determined by performing the `At Expiry` process. - -To create a baseline for the uSTONKS index, a base price for each stock was chosen. These prices are the closing prices of each on 12/31/2020 and can be used by voters as reference values for their calculations. Voters are highly encouraged to verify these values themselves. This basket is static - it will not change over the life of the contract. - -| Ticker | Stock Price 12/31/2020 | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| GME | 18.84 | -| AMC | 2.12 | -| NOK | 3.91 | -| BB | 6.63 | -| SLV | 24.57 | -| TSLA | 705.67 | -| PLTR | 23.55 | -| SNDL | 0.47 | -| AAPL | 132.69 | -| SPCE | 23.73 | - -Each stock also is assigned an index value base. The index is equally weighted, so each stock is assigned a base of 10. This means that on 12/31/2020 at close, the uSTONKS index would have been worth 100 with every component making up 1/10th of that index. - -To calculate the uSTONKS price, an UMA voter should: -1. Query for the close price of one component on March 31, 2021. It is recommended that voters use the Google Sheets GOOGLEFINANCE function. -2. Divide the March 31 price by the base price and multiply by the index value base (10) to get today’s index value. -3. Perform this function for each component in the index and sum all of the results together. -4. Round the result of step three to six decimal places - -An example of this calculation is shown in [this](https://docs.google.com/spreadsheets/d/1AtNzHvn_0na1miktsF2vmmB5fRj2_y793r-j7_m7P8M/edit?usp=sharing) Google Sheet. - -It is possible that, over the life of this price identifier, certain situations could arise that would affect the validity of the index calculation. Guidance is provided below for certain situations, but voters are free to come to an alternative consensus if a flaw in the methodology is identified or an unforeseen event occurs. - -1. In the case of a stock split, the base price of the stock should be divided by the number of shares that the stock is being split into. As an example - if AMC issued a 4:1 stock split, the base price of AMC, 2.12, would be divided by 4 and the new base index price would be 0.53. -2. In the case of a stock consolidation, the process is the same as for a stock split, except the base price should be multiplied by the number of shares being consolidated. - -**Before Expiry** - -If the price request's UTC timestamp is less than 1619812800 (April 30, 2021 @ 4:00PM EST), voters will need to calculate a 2-hour TWAP for the uSTONKS_APR21 token’s price in USDC. The following process should be used to calculate the TWAP. -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the uSTONKS_APR21 / USDC pool returns in the latest block where the block timestamp is <= the price request timestamp. This is the price of 1 uSTONKS_APR21 token in USDC. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. This results should be rounded to 6 decimals. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -## Security Considerations -Security considerations are focused on the use of the token price for monitoring collateral ratios. -- Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -- Mismatch between TWAP and gap higher in token price - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uSTONKS_APR21, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio.

Current liquidity is low, and cross-exchange price discrepancies are 5%+. Over time, as more $COMP supply becomes available, we anticipate that cross-exchange price discrepancies will be reduced. - -Opportunity: A synthetic token that tracks $COMP would enable better price discovery by making it possible to short $COMP. It could be used as a hedging tool. It also increases yield for $COMP holders (who could sell $COMP to buy synthetic $COMP when there are negative funding rates to do so). - -## Technical Specification - -The definition of this identifier should be: -- Identifier name: COMPUSD -- Base Currency: USD(T) -- Quote Currency: COMP -- Exchanges: Coinbase Pro (COMPUSD), Poloniex (COMPUSDT), FTX (COMPUSD) -- Result Processing: Median -- Input Processing: None. Human intervention in extreme circumstances where the result differs from broad market consensus. -- Price Steps: 0.00001 (5 decimals in more general trading format) -- Rounding: Closest, 0.5 up -- Pricing Interval: 60 seconds -- Dispute timestamp rounding: down -- Scaling Decimals: 18 (1e18) - -As of the time of writing, the Coinbase Pro market for $COMPUSD is not yet live, though it is expected to go live on Monday, June 22, 2020. Until the Coinbase Pro market officially goes live and starts trading, the technical specification of this identifier is to take the median of available exchanges (eg Poloniex COMPUSDT and FTX COMPUSD). Once Coinbase Pro is live and stable, the technical specification of this identifier will be the median across Coinbase Pro, Poloniex, and FTX. - -## Rationale -Prices are primarily used by Priceless contracts to calculate a synthetic token’s redemptive value in case of liquidation or expiration. Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. - -More complex computations (like incorporating additional exchanges, calculating a TWAP or VWAP, or imposing price bands, etc.) have the potential to add a greater level of precision and robustness to the definition of this identifier, particularly at settlement of each expiring synthetic token. However, we felt that the costs in increased complexity and mental load to the stakeholders who need to use it (like sponsors, liquidators, and disputers) outweighed the benefits, especially during this period where the $COMP token is newly launched and being listed on additional exchanges. - -Currently the only exchanges with USD or stablecoin markets for $COMP are Coinbase (as of Monday, June 22), FTX, and Poloniex. The price discrepancy across exchanges can be high since $COMP is a low liquidity token. Over time, as liquidity in the $COMP token migrates across platforms, this identifier can be re-defined to add exchanges, remove exchanges, or change the way that the price is calculated. Any re-definition would be done via off-chain social consensus by $UMA-holders, and ultimately reflected in the way that $UMA-holders vote upon the price of $COMPUSD when called to do so by disputers, or at settlement. - - -## Implementation - -The value of this identifier for a given timestamp should be determined by querying for the price of COMPUSD(T) from Coinbase, FTX, and Poloniex for that timestamp, taking the median, and determining whether that median differs from broad market consensus. This is meant to be vague as the $UMA tokenholders are responsible for defining broad market consensus. - -Ultimately, how one queries the exchanges should be varied and determined by the voter to ensure that there is no central point of failure. - -While it's important for tokenholders to have redundancy in their sources, bots and users that interact with the system in realtime need fast sources of price information. In these cases, it can be assumed that the exchange median is accurate enough. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/financial-templates-lib/price-feed/CryptoWatchPriceFeed.js) -is a reference implementation for an offchain price feed based on the -[CryptoWatch API](https://docs.cryptowat.ch/rest-api/).

Users are encouraged to build their own offchain price feeds that depend on other sources. - -## Security considerations -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. diff --git a/research/uma/umips/UMIPs/umip-50.md b/research/uma/umips/UMIPs/umip-50.md deleted file mode 100644 index 4885087a..00000000 --- a/research/uma/umips/UMIPs/umip-50.md +++ /dev/null @@ -1,252 +0,0 @@ - -## HEADERS -| UMIP-50 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add YAMETH, ETHYAM, YAMUSD, and USDYAM as price identifiers | -| Authors | Ross (ross@yam.finance) -| Status | Approved | -| Created | January 28th, 2021 -| Forum Post | https://discourse.umaproject.org/t/add-yam-usd-and-yam-eth-price-identifiers/171 - -# SUMMARY - -The DVM should support price requests for the following indexes - - - YAM/ETH - - ETH/YAM - - YAM/USD - - USD/YAM - - -# MOTIVATION - -The DVM currently does not support the YAMETH, ETHYAM, YAMUSD or USDYAM price indices. - -Supporting the YAMUSD price identifier would enable the creation of a YAM backed stablecoin, built using one of the perpetual stablecoin frameworks being developed on UMA.

This upgrade -will allow price requests to include a data blob of arbitrary length (up to 8192 bytes) to provide additional arguments -or data for the price resolution process. - -## Motivation & Rationale - -Governance votes are extremely common and fairly costly. The largest contributor to governance votes is the requirement -for any contract that wants to track a new asset to have a new identifier approved for that asset. This means the -developer who's deploying this contract must write a new UMIP, the team must review, and all voters must submit votes -to approve the new identifier. That's a lot of effort considering most price identifiers are not controversial, and -their prices are often pulled from the similar sources as existing price identifiers. - -A similar issue is presented when contracts want the DVM to provide more arbitrary computation. One could imagine -options contracts that need to have identifiers that return prices based on the option expiry and the strike price -in addition to the timestamp of the price request. Right now, the DVM only allows users to pass in a single timestamp -to note the time at which the price was requested. Unless a new identifier were created for each expiry, strike price -combination, there is no way for the DVM to price something as complex as an option. There are other, more complex use -cases for the DVM performing "decentralized computation" rather than just looking up a price. - -The solution to these problems is giving deployers the ability to define price identifiers that take arbitrary -parameters. - -In the first example, users can create meta price identifiers that define the _types_ of prices that can -be requested. For instance, a price identifier could allow any asset listed on Uniswap, Sushiswap, Balancer, Binance, -Coinbase, FTX, Huobi, OKEX, or Kraken. The user could provide a list of exchanges and the way they're identified on -each exchange in the ancillary data, which could be decoded by voters and bots alike. - -In the second example, an option price identifier could be created and users could encode the expiry and strike price -in their ancillary data, which would give voters and bots the ability to compute the true price of any option without -needing many distinct identifiers. - -## Technical Specification - -This UMIP adds a Voting contract that is effectively identical to the previous Voting contract, except that most -methods now accept an additional `ancillaryData` argument.

- -# Security Considerations -AAVE, LINK, SNX, UMA, and UNI have shown to be persistently valuable ERC20 tokens given their liquidity and top market capitalization, including them as collateral currencies should impose no additional risk to the protocol. - -The only security implication is for contract deployers and users who are considering using EMP contracts with AAVE, LINK, SNX, UMA, or UNI as the collateral currency. They should recognize that, relative to most fiat currencies, these assets are much more volatile. This volatility should be taken into account when parameterizing or using these EMP contracts. diff --git a/research/uma/umips/UMIPs/umip-57.md b/research/uma/umips/UMIPs/umip-57.md deleted file mode 100644 index eb188686..00000000 --- a/research/uma/umips/UMIPs/umip-57.md +++ /dev/null @@ -1,650 +0,0 @@ - **Headers** -| UMIP-57 | | -|------------|------| -| UMIP Title | Add price identifiers for AAVEUSD, USDAAVE; LINKUSD, USDLINK; SNXUSD, USDSNX; UMAUSD, USDUMA; UNIUSD, USDUNI | -| Authors | Josh Bowden (josh@ferrosync.io) | -| Status | Approved | -| Created | February 17th, 2021 | -| Discourse Link| -
- -# Overview -This proposal is for adding the following price identifiers to be supported: - - * AAVEUSD, USDAAVE - * LINKUSD, USDLINK - * SNXUSD, USDSNX - * UMAUSD, USDUMA - * UNIUSD, USDUNI - -# Motivation - -The purpose of adding these price identifiers is to be able to mint synthetic tokens priced at the defi protocol's token valued against USD. By doing so, users who mint synthetic tokens and sell them to the market are able to short the protocol. Similarly, users who buy the synthetic token are able to long the protocol. - -If the inverse price identifier is used (e.g. USD/UMA) and the same altcoin token is employed as collateral, then the value of the synthetic token can be traded in place of the underlying collateral without having to sell the underlying asset. - -# Rationale -For each altcoin token, we choose to have both `XYZUSD` and `USDXYZ` price identifiers (where the symbol `XYZ` is either `AAVE`, `LINK`, `SNX`, `UMA`, `UNI`) to allow for financial products that use either the altcoin token or stable USDC as collateral. - * Using USDC as collateral allows for speculating on the price of `XYZUSD` -- risking liquidation if the price of the altcoin increases relative to USD. - * Using the altcoin as collateral allows for borrowing synthetic USDC equivalents tracking `USDXYZ` -- risking liquidation if altcoin *decreases* in value relative to USD. - -We picked the top 3 exchanges by trading volume to avoid price movements solely to do poor liquidity. - -A time interval of 1 minute is the most granular time interval supported by the API. We choose a small time interval to ensure that positions track with any large price movements that may occur -- given that this may be a volatile instrument. - -We choose to use a median of three exchanges to balance the overhead of additionally required API calls for liquidation bots between an increased sample size of market prices. The median of the prices was choose instead of a simple arithmetic average to handle the scenarios where a given exchange is halted, unresponsive, or has erratic price movement. - -Quoted prices in USD are rounded to 6 amounts since (i) the USDC ERC20 contract only has 6 decimal places, and (ii) most exchanges only quote prices in USD between 2 to 6 decimal places. We've done the same (i.e. round to 6 decimal places) as well for all `USDXYZ` inverse price identifier for implementation and voting simplicity. - -

If a `twapLength` key value pair is not present, then the spot price should be used. - -When the ancillary data dictionary "twapLength:7200" is stored as bytes, the result would be: 0x747761704c656e6774683a37323030 - -### Technical Specifications - -#### UNI/USD - -- Price Identifier Name: `UNIUSD` -- Base Currency: UNI -- Quote Currency: USD -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) -- Does the value of this collateral currency match the standalone value of the listed quote currency?: YES -- Is your collateral currency already approved to be used by UMA financial contracts?: YES - -#### USD/UNI - -- Price Identifier Name: `USDUNI` -- Base Currency: USD -- Quote Currency: UNI -- Intended Collateral Currency: UNI -- Scaling Decimals: 18 -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) -- Does the value of this collateral currency match the standalone value of the listed quote currency?: YES -- Is your collateral currency already approved to be used by UMA financial contracts?: In progress - -### Implementation - -Voters should query for the price of UNI/USD at the price request timestamp on Coinbase Pro, Binance & OKEx. Recommended endpoints are provided in the markets and data sources section. - -1. When using the recommended endpoints, voters should use the open price of the 1 minute OHLC period that the timestamp falls in. -2. The median of these results should be taken -3. The median from step 2 should be rounded to six decimals to determine the UNIUSD price. -4. The value of USDUNI will follow the exact same process but undergo one additional step: it will be the result of dividing 1/UNIUSD and rounding to the nearest 18 decimal places (nineteenth decimal place digit >= 5 rounds up and < 5 rounds down). -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -If a `twapLength` is present in ancillary data, voters should calculate a TWAP with over that time period rather than calculating the spot price. - -### Rationale - -See "Rationale" section at the beginning of this UMIP as applied to `UNIUSD` and `USDUNI`. - -
- -# Security Considerations -Adding these new identifiers by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing these identifiers should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for these identifiers and also contemplate de-registering these identifiers if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness is necessary to prevent market manipulation. diff --git a/research/uma/umips/UMIPs/umip-58.md b/research/uma/umips/UMIPs/umip-58.md deleted file mode 100644 index 86e0464d..00000000 --- a/research/uma/umips/UMIPs/umip-58.md +++ /dev/null @@ -1,74 +0,0 @@ -# Headers -| UMIP-58 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add UNI-V2 LP tokens WBTC-ETH, USDC-ETH, UNI-ETH, and UMA-ETH, as whitelisted collateral currencies | -| Authors | Dev-1 (dev-1-lp-dollar), Dev-2 (dev-2-lp-dollar) | -| Status | Approved | -| Created | February 09, 2021 | -| Link to Discourse | [Discourse](https://discourse.umaproject.org/t/add-uni-v2-wbtc-eth-as-a-supported-collateral-currency/149) | - -## Summary -This UMIP will add the following UNI-V2 LP tokens as approved collateral currencies: WBTC-ETH, USDC-ETH, UNI-ETH, and UMA-ETH. - -This will involve adding the currencies to the whitelist and adding a flat final fee to charge per-request.

All tokens are widely used across the cryptocurrency space, and account for a large amount of activity in the decentralized finance space. - -UNI-V2 LP tokens as a collateral type are expected to have a variety of deployments. They will open the door for the creation of synthetic assets with CFMM positions. - -## Technical Specification -To accomplish this upgrade, two changes need to be made for each UNI-V2 pair: - -*WBTC-ETH* -- The UNI-V2 WBTC-ETH LP address, 0xBb2b8038a1640196FbE3e38816F3e67Cba72D940, needs to be added to the collateral currency whitelist. -- A final fee of 0.0000002 needs to be added for UNI-V2 WBTC-ETH LP in the Store contract. - -*USDC-ETH* -- The UNI-V2 USDC-ETH LP address, 0xB4e16d0168e52d35CaCD2c6185b44281Ec28C9Dc, needs to be added to the collateral currency whitelist. -- A final fee of 0.0000035 needs to be added for UNI-V2 USDC-ETH LP in the Store contract. - -*UNI-ETH* -- The UNI-V2 UNI-ETH LP address, 0xd3d2E2692501A5c9Ca623199D38826e513033a17, needs to be added to the collateral currency whitelist. -- A final fee of 0.55 needs to be added for UNI-V2 UNI-ETH LP in the Store contract. - -*UMA-ETH* -- The UNI-V2 UMA-ETH LP address, 0x88D97d199b9ED37C29D846d00D443De980832a22, needs to be added to the collateral currency whitelist. -- A final fee of 0.8 needs to be added for UNI-V2 UMA-ETH LP in the Store contract. - - -## Rationale -The rationale behind this change is giving deployers more useful collateral currency options. This is an advancement into a better type of collateral. - -$400 USD equivalent was chosen as the final fee because it is equal to or above the mimimum of already approved coins. - -## Implementation - -This change has no implementation other than proposing the two aforementioned governance transactions that will be proposed. - -## Security Considerations -Since the underlying tokens are persistently valuable tokens, including the packaged version from the Uniswap product as supported collateral currencies should impose no additional risk to the protocol. - -The main implication is for contract deployers and users who are considering using contracts with these assets as the collateral currency. They should recognize and accept the volatility risk of using this, and ensure appropriate required collateralization rations (120%+), as well as a network of liquidator and support bots to ensure solvency. - -As mentioned above, the asset is packaged from Uniswap, a decentralized protocol on the Ethereum blockchain. Uniswap is one of the most popular, proven, and secure smart contract protocols to exist in decentralized finance and beyond. They've succesfully locked up and handled billions of dollars over the course of multiple years, with multiple extensive auditing from top names in the industry. There is the theoretical risk that the pools on Uniswap could be exploited and lead to a rapid loss of value in the currency proposed here which would require fast response to ensure solvency for any financial products built using this as a collateral type. However, due to the nature of Uniswap's long-proven track record around quality and security this is extremely unlikely. diff --git a/research/uma/umips/UMIPs/umip-59.md b/research/uma/umips/UMIPs/umip-59.md deleted file mode 100644 index 87f0f7e5..00000000 --- a/research/uma/umips/UMIPs/umip-59.md +++ /dev/null @@ -1,700 +0,0 @@ -## Headers -| UMIP-59 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add USD/UNI_V2_WBTC_ETH_LP, USD/UNI_V2_USDC_ETH_LP, USD/UNI_V2_UNI_ETH_LP, USD/UNI_V2_UMA_ETH_LP token price identifiers | -| Authors | Dev-1 (dev-1-lp-dollar), Dev-2 (dev-2-lp-dollar) | -| Status | Approved | -| Created | February 09, 2021 | -| Link to Discourse | [Discourse](https://discourse.umaproject.org/t/add-usd-uni-v2-wbtc-eth-as-a-price-identifier/148) | - -## Summary - -The DVM should support price requests for the following Uniswap V2 LP tokens: WBTC-ETH, USDC-ETH, UNI-ETH, UMA-ETH. - -## Motivation - -The DVM currently does not support Uniswap V2 LP tokens. - -By enabling LP token price identifiers, UMA will open the door for the creation of synths with CFMM (constant function market maker) LP positions. - -The price identifiers will enable fixed borrowing costs for Uniswap V2 liquidity providers (LPs) of WBTC-ETH, USDC-ETH, UNI-ETH, and UMA-ETH.

Including any Tether pair means the prices could change due to the price of Tether. However, we decided that these two factors sufficiently mitigate this risk: the purpose of the DVM is to give token holders leeway to evaluate events, such as this, and adjust the price response accordingly. This is adequately captured by the language "determining whether that median differs from broad market consensus." Second, the USDT price could only have the effect of pulling the median towards the higher or lower of the 2 USD pairs. Or, it could fall right in between them. For this reason we believe the USDT concern is sufficiently handled. - -We also considered an alternative set of exchanges.

- -# SUMMARY - -The DVM should support price requests for the below price indexes: -- DIGG/BTC -- DIGG/ETH -- DIGG/USD - -# MOTIVATION - -The DVM currently does not support the DIGG/BTC, DIGG/ETH or DIGG/USD price identifiers. - -DIGG is an elastic supply token pegged to the price of Bitcoin and governed by the Badger DAO. DIGG is currently pegged to 1 BTC, and uses a custom oracle to determine the necessary change in supply. If DIGG price is above 1.05 BTC, DIGG supply increases. This is known as a positive rebase. If DIGG price is below 0.95 BTC, DIGG supply decreases. This is known as a negative rebase. If DIGG price is between 0.95 and 1.05 BTC, DIGG does not rebase. Every DIGG holder gets the same increase or decrease in supply every rebase. - -Supporting the ability to obtain price exposure of DIGG against BTC, ETH, and USD would allow traders to hedge, speculate, and obtain long/short exposure while retaining WBTC or ETH exposure. Many users of these synthetic assets may be Badger yield farmers who want to hedge or arbitrage the DIGG rate. An example of someone who may want to use DIGGBTC would be when the DIGG price is higher than BTC and a trader has DIGG exposure earning a high annual yield along with the inflation rewards described above. Instead of selling DIGG, a user can hedge their DIGG exposure by keeping DIGG and separately using the UMA approved collateral types described in the Technical Specifications to mint DIGGBTC synthetic tokens and sell to the market. If the DIGGBTC rate decreases the user is able to buy DIGGBTC tokens back for less and receive their collateral at a lower DIGGBTC rate. In the opposite situation where DIGG is trading below the Bitcoin price, a DIGGBTC synthetic may be an attractive option for traders who believe the DIGGBTC rate will increase but do not want to be exposed to the daily rebases. - -In both of these situations the exchange rate of DIGG may be impacted by the rebases. However, the synthetic token only exposes the user to the price of DIGG against BTC/ETH/USD.

- -# RATIONALE - -**Why this implementation of the identifier as opposed to other implementation designs?** - -This implementation is due to DIGG's main sources of liquidity being on Sushiswap and Uniswap. Currently, only one low volume and low depth centralized exchange has DIGG listed, and most liquidity will remain on DEXs as it is incentivized. - -**What analysis can you provide on where to get the most robust prices? (Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges)** - -Sushiswap and Uniswap have the vast majority of DIGG volume and depth. These should be used over all other sources. - -**What is the potential for the price to be manipulated on the chosen exchanges?** - -DIGG is not a collateral on any loan services and the majority of the liquidity is locked into farming vaults. The potential risk for this is low. - -**Should the prices have any processing (e.g., TWAP)?** - -A 30 minute TWAP was chosen to help smooth out price changes and give sponsors time to react before becoming undercollateralized. A 30 minute TWAP will also mitigate risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. Another factor influencing the TWAP decision is the daily rebase and its potential impact on the supply and exchange rate which is described further in the Security Considerations section. - -A 24 hour TWAP was chosen for DIGGBTC to be applicable as a price oracle for DIGG rebases. - -
- -# IMPLEMENTATION - -For all implementations, a block number will need to be used. The block number should be the block that is closest to and before the timestamp that the price request timestamp. - -For DIGG/ETH and DIGG/USD TWAP implementations, the TWAP start time should be determined by the latest block 30 minutes before requested timestamp. For DIGG/BTC, it should be 24 hours before. When using DIGG/BTC in DIGG/ETH and DIGG/USD price calculations, a 30 minute TWAP should be used for DIGG/BTC. - -**For DIGG/WBTC** - - 1.

- -# Security considerations - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradeable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. - -DIGG Rebase - When the DIGG supply policy executes its rebase, all DIGG holders balances potentially increase or decrease together in a single transaction which include contracts that hold DIGG balances (Uniswap and Sushiswap). Since the DIGG reserve automatically adjusts, changing the relative size of the DIGG in pools, a new exchange rate is created. Having a 30 minute TWAP will allow the price to adjust after larger supply changes and prevent a higher risk of undercollateralized positions. - -Collateralization Requirements - All three of these identifiers are very volatile which brings on a higher risk of undercollateralized positions in the case of a massive DIGG price increase. Minimum collateral ratios should be higher compared with other price identifiers with ~1.5 being the minimum. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness are necessary to prevent market manipulation. diff --git a/research/uma/umips/UMIPs/umip-62.md b/research/uma/umips/UMIPs/umip-62.md deleted file mode 100644 index 5e58071c..00000000 --- a/research/uma/umips/UMIPs/umip-62.md +++ /dev/null @@ -1,179 +0,0 @@ -## Headers -| UMIP-62 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add ETHBTC_FR as a price identifier | -| Authors | Sean Brown (smb2796), Kevin Chan (kevin-uma) | -| Status | Approved | -| Created | Feb 24, 2021 -| [Discourse Link](https://discourse.umaproject.org/t/add-ethbtc-fr-as-a-supported-price-identifier/260) | - -## SUMMARY - -The DVM should support price requests for a funding rate for the ETH/BTC UMA perpetual. This funding rate represents the change in a synthetic token's value per second. - -*Note*: -This funding rate identifier requires querying for the price of the synthetic token that will be created by a contract using this identifier. Throughout this UMIP, this synthetic will be referred to as ETHBTC-PERP. Since this synthetic has not yet been created, its specific details can not yet be included. This UMIP will be updated once the ETHBTC-PERP has been created to include its address, token name and AMM pool address. - -## MOTIVATION - -Without an expiry date to keep a synthetic token pegged to its underlying price, UMA’s perpetual contract requires that a funding rate be levied when there is a difference between the synthetic’s price and the underlying index. This will pressure the overvalued side to unwind its position or encourage the undervalued side to create a larger position. This mechanic is similar to what centralized exchanges use to keep their perpetual synthetics in line with its underlier. - -Funding rate proposals and disputes function similarly to normal UMA price requests. On request, a proposer can post a bond and propose a new funding rate in return for a reward. If the funding rate proposal is not disputed within its liveness period, that proposed rate is then used to continuously adjust the value synthetic token sponsors' debt. If the proposed funding rate is successfully disputed, the proposer will lose their bond. The bond amount varies between each perpetual contract. - -It should be noted that this is an altered price reporting from what has been used historically by UMA contracts. With the introduction of the [Optimistic Oracle](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-52.md) and new [EMP](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-54.md) and [Perpetual contract](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-53.md) templates, all funding rate and settlement price requests will be handled by the Optimistic Oracle, and will only be sent to the voters of the DVM in the case of a price or funding rate dispute. - -*Note*: -For future funding rates, it is likely that a more generalized funding rate identifier should be created and used. A generalized funding rate identifier would be able to support any funding rate request by making use of [ancillary data](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-55.md#motivation--rationale). This UMIP is reduced in scope and specifically only creates a methodology for the ETHBTC funding rate and is being proposed so that this identifier can be used as an example of how a funding rate would work for a specific synthetic. - -## MARKETS & DATA SOURCES - -- Markets: - -Uniswap: ETHBTC_PERP/DAI -Coinbase Pro: ETH/BTC -Binance: ETH/BTC -Bitstamp: ETH/BTC - -- Live Price Endpoints - -Uniswap prices are on-chain and can be queried in a variety of methods. - -Coinbase Pro: https://api.cryptowat.ch/markets/coinbase-pro/ethbtc/price -Binance: https://api.cryptowat.ch/markets/binance/ethbtc/price -Bitstamp: https://api.cryptowat.ch/markets/bitstamp/ethbtc/price - -- Update time: - -Uniswap - every block. -Cryptowatch: Every 60 seconds - -- Historical Price Endpoints: - -Coinbase Pro: https://api.cryptowat.ch/markets/coinbase-pro/ethbtc/ohlc?after=1613450520&before=1613450520&periods=60 -Binance: https://api.cryptowat.ch/markets/binance/ethbtc/ohlc?after=1613450520&before=1613450520&periods=60 -Bitstamp: https://api.cryptowat.ch/markets/bitstamp/ethbtc/ohlc?after=1613450520&before=1613450520&periods=60 - -- Do these sources allow for querying up to 74 hours of historical data?

This funding rate will be used to keep the price of the ETHBTC-PERP synthetic pegged to the ETHBTC rate times the cumulative funding rate multiplier (CFRM). The funding rate will be determined with the following formula: -- [ETHBTC-PERP - ETHBTC-FV] / ETHBTC-FV / 86400 -- `ETHBTC-FV` denotes the ETHBTC price gathered with the methodology shown in [UMIP-2](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-2.md) multiplied by the CFRM. -- `ETHBTC-PERP` denotes the one hour TWAP of the synthetic created with this funding rate identifier. This synth will be pooled with DAI. -- 86400 is the number of seconds in a day. Assuming all other prices stay constant, this effectively gives the funding rate per second that would need to be applied to move a synthetic token's value back to fair value in one day. - -A one hour TWAP is used for the ETHBTC-PERP and ETHBTC-FV rates. This calculation was modeled off of the [FTX Funding rate calculation](https://help.ftx.com/hc/en-us/articles/360027946571-Funding), which also uses a 1-hour TWAP. - -86400 was chosen for two reasons. The current funding rate is continuously applied to sponsors' positions, so the proposed funding rate needs to be adjusted to a rate that reflects a continuous rate (per second rate). A day was chosen as the interval to move the fair value and perpetual price back to peg, because this follows existing and proven patterns created by CEX's like FTX. - -Min and max bounds of -0.00001 and 0.00001 were chosen because these are the funding rate calculations that represent a 100% drift of perp from peg. You can arrive at these amounts with 1/86400. - -## IMPLEMENTATION -To calculate the ETHBTC-FR, voters should use the following process: - -1. Following the specifications in [UMIP-2](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-2.md), query for the 1-hour ETHBTC TWAP, ending at the disputed funding rate proposal timestamp. This will consist of 60 queries for the close price of each 60 second ohlc period in that hour. Note that voters should calculate three separate 1-hour TWAPs, one for each exchange in UMIP-2, and then medianize these. -2. Query for the cumulative funding rate multiplier (CFRM) at the price request timestamp. -3. The 1-hour ETHBTC TWAP and the CFRM should then be multiplied - this result is referred to in future steps as ETHBTC-FV. -4. Query for the ETHBTC-PERP 1-hour TWAP from the listed AMM pool. This will return the ETHBTC-PERP's TWAP denominated in DAI. This rate should be left as is, with no conversion made between DAI and USD. -5. Subtract the result of step 4 from the result of step 3. [ETHBTC-FV - ETHBTC-PERP]. -6. Divide the result of step 5 by the ETHBTC-FV rate from step 4. [ETHBTC-FV - ETHBTC-PERP]/ETHBTC-FV. -7. Divide the result of step 6 by 86400 (# of seconds in a day) to get the funding rate per second. -8. Implement min and max bounds on this result with: max(-0.00001, min(0.00001, result)). -9. Voters should then round this result to 9 decimal places. - -As always, voters should determine whether the returned funding rate differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -### Cumulative Funding Rate Multiplier (CFRM) Calculation - -The contract specific CFRM is stored on-chain for each perpetual contract. Voters can query this on-chain data at the funding rate proposal timestamp in any way that they wish. - -1. Simulate an `applyFundingRate` transaction. An example of this be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/FundingRateMultiplierPriceFeed.js#L86). -2. Call `fundingRate` on the ETHBTC-PERP. - -The results will be in this format: - -``` -{ - rate, - identifier, - cumulativeMultiplier, - updateTime, - applicationTime, - proposalTime -} -``` - -Voters should use the `cumulativeMultipler` value. - -## Security Considerations -Adding this identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of funding rate proposers and disputers that can correctly manage the funding rate process. - -The self-referential nature of this identifier introduces additional security concerns.

They should recognize and accept the volatility risk of using this, and ensure appropriate required collateralization rations (140%+), as well as a network of liquidator and support bots to ensure solvency. - -The DPI Token was created by the DeFI Pulse Index team on top of the Set Protocol. There is the theoretical risk that the underlying smart contracts get exploited which leads to a rapid loss of value in the currency proposed here which would require fast response to ensure solvency for any financial products built using this as a collateral type. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-64.md b/research/uma/umips/UMIPs/umip-64.md deleted file mode 100644 index ea6b2513..00000000 --- a/research/uma/umips/UMIPs/umip-64.md +++ /dev/null @@ -1,381 +0,0 @@ -## Headers -| UMIP-64 | | -|------------|---| -| UMIP Title | Add INDEX/ETH, ETH/INDEX, INDEX/USD, USD/INDEX, DPI/ETH, ETH/DPI, DPI/USD and USD/DPI as price identifiers | -| Authors | Gottlieb Freudenreich (gottlieb.freudenreich@gmail.com) -| Status | Approved | -| Created | 2020-03-08 | -| Discourse Link | https://discourse.umaproject.org/t/add-index-and-dpi-price-identifiers/327 - -# SUMMARY - -The DVM should support price requests for the following indexes - - - INDEX/ETH - - ETH/INDEX - - INDEX/USD - - USD/INDEX - - DPI/ETH - - ETH/DPI - - DPI/USD - - USD/DPI - - -# MOTIVATION - -The DVM currently does not support the INDEX/ETH, ETH/INDEX, INDEX/USD, USD/INDEX, DPI/ETH, ETH/DPI, DPI/USD and USD/DPI price indices. - -Supporting the DPI/USD and INDEX/USD price identifiers would enable the creation of a DPI/INDEX backed stablecoin, built using one of the perpetual stablecoin frameworks being developed on UMA.

- - -# RATIONALE - -Prices are primarily used by Priceless contracts to calculate a synthetic token’s redemptive value in case of liquidation or expiration. Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. More complex computations (like incorporating additional exchanges, calculating a TWAP or VWAP, or imposing price bands, etc.) have the potential to add a greater level of precision and robustness to the definition of this identifier, particularly at settlement of each expiring synthetic token. - -The addition of INDEX/ETH, ETH/INDEX, DPI/USD, and USD/DPI fits into a larger goal of advancing the adoption of the UMA protocol by allowing INDEX and DPI to be used as collateral for minting derivatives within the UMA ecosystem, as well as other UMA based synthetics. This furthers adoption of the protocol by encouraging a convergence of capital from different projects and increasing TVL. - -Using the Uniswap Price should give the most accurate price for DPI/ETH and INDEX/ETH on the market as it has the deepest liquidity. Sushiswap liquidity is increasing but much lower.

In the current setting, there would need to be a significant event that erodes confidence in the Index Cooperative or the DPI token, causing Uniswap liquidity to be withdrawn quickly and en-masse. This threat is mitigated via INDEX incentives paid to liquidity providers who stake their tokens. The price on sushiswap should follow uniswap due to on chain arbitrage unless there is a serious problem with Ethereum. Furthermore, in also querying Binance this risk is minimized. - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. - - - - diff --git a/research/uma/umips/UMIPs/umip-65.md b/research/uma/umips/UMIPs/umip-65.md deleted file mode 100644 index e46716f5..00000000 --- a/research/uma/umips/UMIPs/umip-65.md +++ /dev/null @@ -1,305 +0,0 @@ - -## HEADERS -| UMIP-65 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add uTVL_KPI_UMA as a Price Identifier | -| Authors | Hart Lambur hart@umaproject.org, Mhairi McAlpine mhairi@umaproject.org | -| Status | Approved | -| Created | 4th March 2021 -| [Discourse Link](https://discourse.umaproject.org/t/add-utvl-kpi-uma-as-a-price-identifier/318) | - -# SUMMARY - -Key Performance Indicator(KPI) options are synthetic tokens that redeem to protocol tokens with the redemption value determined by performance against that indicator.

Within UMA, TVL plays the additional function of being the lower floor for the value of 0,5 $UMA, due to the design of UMA and the COC>POC inequality. - -1. What are the financial positions enabled by creating this synthetic that do not already exist? - - - The DVM does not currently support any form of KPI options.

What would be the cost of sending 15,000 queries? - - - There is no need to sent 15, 000 queries for this price identifier as it does not require bots. - -
- -# PRICE FEED IMPLEMENTATION - -As there is no requirement for ongoing monitoring through liquidation or dispute bots, a price feed is not required. The only requirement is a query of the UMA TVL statistic at the timestamp 00.00(UTC) on 30th June according to the data and markets as defined above. - -
- -# TECHNICAL SPECIFICATIONS - -**1. Price Identifier Name** - uTVL_KPI_UMA - -**2. Base Currency** - uTVL_UMA. - -**3. Quote currency** - -If your price identifier is a currency pair, your quote currency will be the -denominator of your currency pair. If your price identifier does not have a quote currency, please explain the reasoning behind this. - -- There is no quote currency, the denominator is fixed at 10^9 (1 Billion) - - - This price identifier does not have a quote currency as it is designed not to be tied to a currency price metric,. - -Please be aware that the value of any UMA synthetic token is the value of the price identifier in units of the collateral currency used. If a contract’s price identifier returns 1, and is collateralized in renBTC, each synthetic will be worth 1 renBTC. In most cases, the value of your quote currency and intended collateral currency should be equal. - -- The collateral redemption is designed to be tied to the value of the TVL of the protocol by design. - -**4. Intended Collateral Currency** - - - UMA - -Does the value of this collateral currency match the standalone value of the listed quote currency? - - - No, this is a design feature. - -Is your collateral currency already approved to be used by UMA financial contracts? If no, submit a UMIP to have the desired collateral currency approved for use. - - - YES - - UMA was approved as a collateral currency in[UMIP 56](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-56.md) - -**5. Collateral Decimals** - - - 18 - - -**6. Rounding** - Round to 2 decimal places. - - - If the price is 1.025, then this would be rounded up to 1.03. If the price is 1.0249999, then this would be rounded down to 1.02. - - if the value returned is less than 0.05 round up to 0.1 to provide a floor price. - - if the value returned is greater that 2 round down to 2 to provide a ceiling price. - -
- -# RATIONALE - -- This synthetic is designed as an incentivisation mechanism to leverage the UMA community, our partners and the wider Defi userbase to grow our protocol as measured by our identified Key Performance Indicator of Total Value Locked. - - - This price identifier offers a guarantee that these options will be of value, even if this key metric is poor through the floor price mechanism, however the nature of UMA is such that the amount of value that can be locked in the protocol is potentially limitless and consequently a ceiling price is required to limit provide a cap. - - - The methods used to calculate the dollar value of each of the collateral currencies have been chosen to adhere to previous design decisions in such calculations through UMIPs that have already been approved through our governance procedure however note the following assumptions. - -1. It is assumed for this purpose that 1wEth = 1Eth - -2. Two forms of wrapped Bitcoin (wBTC, RenBTC) are approved for use as collateral within the UMA Protocol. -It is assumed that for this purpose, 1 renBTC=1wBTC=1BTC. While that assumption may be somewhat inaccurate, it has minimal impact on the overall calculation, cuts down on processing complexity, and works on a “common sense” attitude that wrapped bitcoin on the Eth chain are equivalent in value to native bitcoin. -There are other forms of wrapped BTC which are not approved as collateral within the UMA protocol. To maintain consistency it is suggested that this assumption is made for any other similar non-algorithmic wrapped Bitcoin. - -3. Four non-algorithmic dollar stablecoins (DAI, USDC, USDT, rDai]) are approved as collateral within the UMA Protocol. -It is assumed for this purpose that 1DAI=1USDC=1USDT=1rDAI=$1. While this assumption may be somewhat inaccurate, it has minimal impact on the overall calculation, cuts down on processing complexity and works on a “common sense” attitude that a dollar stablecoin is worth exactly $1. -There are other forms of dollar stablecoins which are not approved as collateral within the UMA protocol. To maintain consistency it is suggested that this assumption is made for any other non-algorithmic stablecoin. - -4. Five Liquidity Tokens (wBTC-Eth, USDC-Eth, UNI-Eth, UMA-Eth, bwBTC/ETH_SLP) are approved as collateral within the UMA protocol. -It is recommended that any additional proposal to add liquidity tokens as approved collateral currencies are evaluated against UMIP 59 and follow those market and data sources to calculate dollar value unless there is good reason for deviance. Note that the calculation of the dollar value of the liquidity token occurs in the penultimate step of the UMIP (Step 5). - -5.There are a variety of price identifiers for native ERC20 tokens. Calculation of the dollar value should follow the relevant UMIP where it exists, and where there is no Price Identifier UMIP, the three highest volume [ERC20]/USD* markets should be queried and the median value used. - - - There is no need for price processing. This is a snapshot based on a particular time, however it may be useful for TVL Options holders to have oversight of the ongoing TVL and consequently the value of their options on an ongoing basis. There are currently two dashboards that track the TVL of UMA - - - [SimpleID](https://monitor.simpleid.xyz/uma) - - [Yuen](https://docs.google.com/spreadsheets/d/e/2PACX-1vSEMURxiVQuu6jSDp2zmI7kdKKaJjgmhWNiVjwStyJekDx9hWgclKzm_yv9iyj82IRP4d9dZ8rgvCCB/pubhtml) - - - These currently monitor different contracts and calculate the value slightly differently. - - - The use of these dashboards was considered but rejected due to the potential for manipulation and the differences between their calculations of the values of the collateral assets and the value as determined by the relevant UMIPs. - - -
- -# IMPLEMENTATION - - - The contracts to be tracked include - - Any EMP contract - - Any Perpetual contract - - Any perpetual pool party contract - - The total value locked is the value of the collateral locked in the relevant contracts. - - The dollar value of each of the contracts should be calculated using the UMIPs and guidence in the Markets and Data section. - - These should then be summed to obtain the total value locked (TVL) measured in dollars. - - The TVL as measured in dollars should then be divided by 10^9 - - - -1. **What prices should be queried for and from which markets?** - - - The dollar value of each of the contracts should be calculated using the UMIPs and guidence in the Markets and Data section. - - Where there is no price identifier UMIP, the price should be queried from the highest volume USD* market - -2. **Pricing interval** - - - This will vary for each value however the relevant UMIPs provide a guide to the pricing interval for each - -3. **Input processing** - - - From the list of ExpiringMultiPartyCreator (available at https://github.com/UMAprotocol/protocol/blob/master/packages/affiliates/payouts/devmining-status.json), query all EMP addresses from createExpiringMultiParty() and call pfc() on all of them, repeat same steps for PerpetualCreator and just check the createPerpetual() event, to identify the amount of each collateral type locked in UMA contracts. - - - The dollar value of each contract should then be calculated using the details supplied in the Markets and Data section referencing the relevant UMIPs - - - These should then be summed to obtain the total value locked (TVL) measured in dollars. - - -4. **Result processing** - - - Divide TVL by 10^9 and apply the floor and ceiling price rounding. - -
- -# Security considerations - -1. Where could manipulation occur? - - - Negligible opportunities for manipulation. - -2. How could this price ID be exploited? - - - It is possible that as expiry approaches, a user may be able to purchase a large number of TVL option on the open market, should the TVL be significantly below the level required to achieve the ceiling level, then add large amounts of collateral to an UMA contract slightly before expiry to temporarily drive up the TVL, redeem the synthetic tokens, then withdraw the collateral immediately afterwards. - - - It is possible that a user may purchase uTVL_KPI_UMA at a low price, lock substantial amounts of collateral in UMA contracts causing the uTVL_KPI_UMA price to rise, then sell the these tokens at a profit and immediately withdraw the collateral from the contracts. - - - It is possible that as expiry approaches a user may purchase a large number uTVL_KPI_UMA at a low price near expiry on the open market should the TVL be significantly below the level required to achieve the ceiling of 2 $UMA per option, then deposit substantial amounts of collateral in UMA contracts with the intention of temporarily driving up the returns from the options, then immediately withdraw the collateral after expiry, causing an artificial spike in the TVL. Technical solutions were explored however it was considered that given the variety of potential manipulation and that whatever constraints put in place to mitigate this could be gamed, the DVM was a superior method of addressing any such attempts. In the event of such a manipulation attempt, and a dispute being raised, voters should come to consensus on what a true measure of the TVL locked in the protocol would have been by excluding the collateral used in the manipulation attempt. - - -3. Do the instructions for determining the price provide people with enough certainty? - - - YES - -4. What are current or future concern possibilities with the way the price identifier is defined? - - - It is likely that new forms of collateral will be approved prior to the expiry date. It is possible that they may not have a significant USD* market. Should a direct calculation not be possible the highest volume ETH market should be queried and conversion to a dollar value performed through UMIP6. - - It is possible that price identifiers for collateral types amy be altered prior to expiry - - It is possible that collateral types may be removed. This would not impact on this PI as they would not feature in any relevant contract. - - -5. Are there any concerns around if the price identifier implementation is deterministic? - - - This price identifier excludes collateral locked in Jarvis contracts and the optimistic oracle contracts. - - diff --git a/research/uma/umips/UMIPs/umip-66.md b/research/uma/umips/UMIPs/umip-66.md deleted file mode 100644 index 46f99512..00000000 --- a/research/uma/umips/UMIPs/umip-66.md +++ /dev/null @@ -1,35 +0,0 @@ -## Headers -| UMIP-66 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add USDBTC_18DEC, BCHNBTC_18DEC, ELASTIC_STABLESPREAD/USDC_18DEC, STABLESPREAD/USDC_18DEC, STABLESPREAD/BTC_18DEC and AMPLUSD_18DEC as supported price identifiers | -| Authors | Sean Brown (@smb2796) | -| Status | Approved | -| Created | March 10, 2021 | -| [Discourse Link](https://discourse.umaproject.org/t/propose-v2-pids-for-all-depreciated-pis/336) | | - - -## Summary (2-5 sentences) - -This UMIP proposes adding USDBTC_18DEC, BCHNBTC_18DEC, ELASTIC_STABLESPREAD/USDC_18DEC, STABLESPREAD/USDC_18DEC, STABLESPREAD/BTC_18DEC, AMPLUSD_18DEC as supported price identifiers. - -## Motivation - -With the introduction of the new EMP template proposed in UMIP-52, all price identifiers are required to be scaled by 10^18 when submitted on-chain. This is in contrast to the function in old EMP contracts, where the price identifier needed to be scaled to match the scaling factor of the collateral currency that the identifier was being used with. This means that price identifiers that are being used in an old EMP contract that has a non-18 decimal collateral currency cannot be used with the new contracts. - -Because of this, many price identifiers have been deprecated. This UMIP simply reproposes those price identifiers with slightly altered price identifier names and a scaling specification of 18 decimals. Everything else about these identifiers remains the same. The intention is that these price identifiers only be used while the original price identifiers are still deprecated. If the original price identifiers are at any point able to be used again, those should once again become the canonical price ids. - -## Technical Specifications - -Voters should refer to the rationale, technical specifications, implementations and security considerations in each corresponding UMIP. The only change to the implemenentations of these price identifiers are that these should all be scaled 10^18. Voters currently do not have to adjust results for any sort of scaling when voting through the UMA voter dapp, so the result that a voter would input for one of these price ids would be exactly the same as for the deprecated identifiers. - -The price identifier pairings are as follows. - -| New Identifier | Old Identifier | UMIP | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| --------------| -| USDBTC_18DEC | USDBTC | [UMIP-7](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-7.md) | -| BCHNBTC_18DEC | BCHNBTC | [UMIP-23](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-23.md) | -| ELASTIC_STABLESPREAD/USDC_18DEC | ELASTIC_STABLESPREAD/USDC | [UMIP-30](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-30.md) | -| STABLESPREAD/USDC_18DEC | STABLESPREAD/USDC | [UMIP-31](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-31.md) | -| STABLESPREAD/BTC_18DEC | STABLESPREAD/BTC | [UMIP-31](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-31.md) | -| AMPLUSD_18DEC | AMPLUSD | [UMIP-33](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-33.md) | - diff --git a/research/uma/umips/UMIPs/umip-67.md b/research/uma/umips/UMIPs/umip-67.md deleted file mode 100644 index edf60adb..00000000 --- a/research/uma/umips/UMIPs/umip-67.md +++ /dev/null @@ -1,44 +0,0 @@ -## Headers -| UMIP-67 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add SUSHI and xSUSHI as approved collateral currencies | -| Authors | Sean Brown (@smb2796) | -| Status | Approved | -| Created | March 10, 2021 | -| [Discourse Link](https://discourse.umaproject.org/t/add-sushi-and-xsushi-as-collateral-types/335) | | - -## Summary (2-5 sentences) -This UMIP will add Sushi and xSushi as approved collateral currencies. This will involve adding these to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 25 SUSHI and 22 xSUSHI per request. - -## Motivation - -SUSHI and xSUSHI are both ERC-20 tokens used by the SushiSwap community. SUSHI is the governance token of SushiSwap and is also used for staking. When SUSHI holders stake SUSHI, they receive xSUSHI in return. Each xSUSHI is thus exchangeable for a certain amount of staked SUSHI tokens. - -Adding SUSHI and xSUSHI as collateral types will allow for a variety of contract deployments. These could be used with the SUSHI/xSUSHI price identifiers that are also being proposed, to create SUSHI/xSUSHI backed yield dollars, or SUSHI/xSUSHI covered calls. - -## Technical Specification -To accomplish this upgrade, two changes for each currency need to be made: - -### SUSHI -- The SUSHI address, [0x6B3595068778DD592e39A122f4f5a5cF09C90fE2](https://etherscan.io/address/0x6b3595068778dd592e39a122f4f5a5cf09c90fe2), needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 25 needs to be added for SUSHI in the Store contract. - -### xSUSHI -- The xSUSHI address, [0x8798249c2E607446EfB7Ad49eC89dD1865Ff4272](https://etherscan.io/address/0x8798249c2E607446EfB7Ad49eC89dD1865Ff4272), needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 22 needs to be added for xSUSHI in the Store contract. - -## Rationale - -The rationale behind this change is giving deployers more useful collateral currency options. - -25 was chosen as the final fee for SUSHI, because this is approximately ~$500 at current SUSHI prices whcih is approximately equivalent to other collateral currencies. A slightly lower xSUSHI final fee of 22 was chosen, because xSUSHI will always trade slightly higher than SUSHI and this results in the same approximate dollar value. - -## Implementation - -This change has no implementation other than the two aforementioned governor transactions that will be proposed. - -## Security considerations - -The only security implication is for contract deployers and users who are considering using EMP contracts with SUSHI or xSUSHI as collateral currencies. Contract deployers and users of SUSHI and xSUSHI should be aware that these are both volatile currencies and sponsors should take care to keep their positions over-collateralized when using these. - -Since xSUSHI primarily functions as a SUSHI LP token, it does not have many liquid markets available.

Both will use the [Cryptowatch](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/CryptoWatchPriceFeed.js), [Uniswap](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) and [Expression](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/ExpressionPriceFeed.js) price feeds to get the price of SUSHIUSD. The XSUSHI identifiers will also use the [LPPriceFeed](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/LPPriceFeed.js) to determine the amount of SUSHI that each XSUSHI is redeemable for. - -The default price feed config for SUSHIUSD would follow this pattern: - -``` -SUSHIUSD: { - type: "expression", - expression: ` - SPOT_SUSHISWAP = SPOT_SUSHISWAP_ETH * ETHUSD; - median(SPOT_BINANCE, SPOT_HUOBI, SPOT_SUSHISWAP) - `, - lookback: 7200, - minTimeBetweenUpdates: 60, - customFeeds: { - SPOT_BINANCE: { type: "cryptowatch", exchange: "binance", pair: "sushiusdt" }, - SPOT_HUOBI: { type: "cryptowatch", exchange: "huobi", pair: "sushiusdt" }, - SPOT_SUSHISWAP: { type: "uniswap", address: "0x795065dCc9f64b5614C407a6EFDC400DA6221FB0" }, - ETHUSD: { - type: "medianizer", - minTimeBetweenUpdates: 60, - medianizedFeeds: [ - { type: "cryptowatch", exchange: "coinbase-pro", pair: "ethusd" }, - { type: "cryptowatch", exchange: "binance", pair: "ethusdt" }, - { type: "cryptowatch", exchange: "kraken", pair: "ethusd" } - ] - } - } -} -``` - -The default price feed config for XSUSHIUSD would follow this pattern: - -``` -SUSHIUSD: { - type: "expression", - expression: ` - SPOT_SUSHISWAP = SPOT_SUSHISWAP_ETH * ETHUSD; - SUSHIUSD = median(SPOT_BINANCE, SPOT_HUOBI, SPOT_SUSHISWAP); - SUSHIUSD * SUSHI_PER_SHARE - `, - lookback: 7200, - minTimeBetweenUpdates: 60, - customFeeds: { - SPOT_BINANCE: { type: "cryptowatch", exchange: "binance", pair: "sushiusdt" }, - SPOT_HUOBI: { type: "cryptowatch", exchange: "huobi", pair: "sushiusdt" }, - SPOT_SUSHISWAP: { type: "uniswap", address: "0x795065dCc9f64b5614C407a6EFDC400DA6221FB0" }, - ETHUSD: { - type: "medianizer", - minTimeBetweenUpdates: 60, - medianizedFeeds: [ - { type: "cryptowatch", exchange: "coinbase-pro", pair: "ethusd" }, - { type: "cryptowatch", exchange: "binance", pair: "ethusdt" }, - { type: "cryptowatch", exchange: "kraken", pair: "ethusd" } - ] - }, - SUSHI_PER_SHARE: { - type: "lp", - poolAddress: "0x8798249c2E607446EfB7Ad49eC89dD1865Ff4272", - tokenAddress: "0x6b3595068778dd592e39a122f4f5a5cf09c90fe2" - }, - } -} -``` - -The same configs would hold true for USDXSUSHI or USDSUSHI, with the added step of taking the inverse of the XSUSHIUSD or SUSHIUSD rates. - -## TECHNICAL SPECIFICATIONS - -- Price Identifier Name: SUSHIUSD -- Base Currency: SUSHI -- Quote currency: USD -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -- Price Identifier Name: USDSUSHI -- Base Currency: USD -- Quote currency: SUSHI -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -- Price Identifier Name: XSUSHIUSD -- Base Currency: XSUSHI -- Quote currency: USD -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -- Price Identifier Name: USDXSUSHI -- Base Currency: USD -- Quote currency: XSUSHI -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE - -The three markets chosen for pricing SUSHI/USD were picked because they are three of the highest daily trading volume markets available. - -SushiSwap has lower daily volume than some other CEXs like OKEx, but it seems correct to use SushiSwap since it is SUSHI's native market and will assumably continue to have one of the highest trading volumes. - -Typically it is best practice to use a TWAP when pricing with DEX markets. A TWAP is not used in this implementation because SushiSwap is only one of the three sources used for the median, so any irregular price action or attempted manipulation will be invalidated anyways. - -## IMPLEMENTATION - -### SUSHIUSD and USDSUSHI - -1. For the price request timestamp, query for the SUSHIUSDT prices on Binance and Huobi and the ETHUSD price by following the guidelines of UMIP-6. The open price of the 60-second OHLC period that this price request timestamp falls in should be used. -2. For the block of the price request timestamp, query for the SUSHIETH price from SushiSwap. -3. Multiply the gathered ETHUSD price by SUSHIETH to get the SushiSwap SUSHIUSD price. -4. Take the median of these. -5. Round to 6 decimals to get the SUSHIUSD price. -6. To get the USDSUSHI price, voters should just take the inverse of SUSHIUSD from step 5. - -### XSUSHIUSD and USDXSUSHI - -As noted in the Rationale section, XSUSHI is a LP token given specifically to SUSHI token stakers. 1 XSUSHI is equivalent to a number of SUSHI tokens represented by the total amount of SUSHI locked in the XSUSHI contract divided by the total supply of XSUSHI. - -1. At the block that the price request timestamp is at, the `balanceOf` [SUSHI](https://etherscan.io/address/0x6b3595068778dd592e39a122f4f5a5cf09c90fe2) for the XSUSHI contract address, [0x8798249c2E607446EfB7Ad49eC89dD1865Ff4272](https://etherscan.io/address/0x8798249c2e607446efb7ad49ec89dd1865ff4272), needs to be queried for. -2. Voters should then query for the `totalSupply` of XSUSHI in the same block. -3. The `balanceOf` SUSHI should be divided by the `totalSupply` of XSUSHI to determine the number of SUSHI that each XSUSHI is worth. -4. The price of SUSHIUSD should then be gathered in the same manner as explained in the section above. -5. The result of step 3 and step 4 should be multiplied to get the price of XSUSHIUSD. Voters should then round this result to 6 decimal places. -6. USDXSUSHI follows the same pattern except adds the additional step of taking the inverse of the XSUSHIUSD result. - -## Security Considerations - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -There are some security considerations associated with adding a low float token like XSUSHI as collateral. These are explained further in the XSUSHI collateral UMIP. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-69.md b/research/uma/umips/UMIPs/umip-69.md deleted file mode 100644 index 3f0e2558..00000000 --- a/research/uma/umips/UMIPs/umip-69.md +++ /dev/null @@ -1,293 +0,0 @@ -## HEADERS -| UMIP-69 | | -|------------|------------| -| UMIP Title | Add BCHDOM, BNBDOM, BSVDOM, DOTDOM, ETHDOM, LINKDOM, LTCDOM, USDTDOM & XRPDOM as price identifiers | -| Authors | Domination Finance (Josh Bowden (), Michal Cymbalisty (), et. al.) -| Status | Approved | -| Created | March 16, 2021 | -| Link to Discourse | https://discourse.umaproject.org/t/add-bchdom-bnbdom-bsvdom-dotdom-ethdom-linkdom-ltcdom-usdtdom-xrpdom-as-price-identifiers/346 | -

Compared to other typical UMIP price identifiers, these indices are *unit-less* since they are simply a percentage represented as a whole number. - -Each price identifier for a particular cryptocurrency's market share in general is calculated by taking, - * the total *circulating* supply of that cryptocurrency, - * multiplied by the current price of the token in USD, - * divided by the global market cap of all cryptocurrencies. - -The price identifiers are constructed using the following formulations below. - -> **REMARK**  The formulas shown below gives the reader a general concept of how one arrives at the prices of these indices. In general, there can be significant deviations and methodology as to how data providers actually calculate coin dominance. Calculating global cryptocurrency market cap involves curating 5000+ coins, in CoinGecko's case, as querying live USD prices and outstanding supply of each of those coins on the market -- as well as providing accessible API access. We give a more long form explanation in "Rationale". - -> **REMARK**  The actual price identifier values are whole numbers out of 100. For example, a value of 12.34% is represented as the value -> raw decimal value of `12.34`. Therefore, all price identifier values for dominance indices will always be within the range `0.00 <= x < 100.00`, for some dominance index value `x`. - -``` -BCHDOM → [Total BCH circulating supply] - * [Price of BCHUSD] - / [Total crypto market cap (USD)] - -BNBDOM → [Total BNB circulating supply] - * [Price of BNBUSD] - / [Total crypto market cap (USD)] - -BSVDOM → [Total BSV circulating supply] - * [Price of BSVUSD] - / [Total crypto market cap (USD)] - -DOTDOM → [Total DOT circulating supply] - * [Price of DOTUSD] - / [Total crypto market cap (USD)] - -ETHDOM → [Total ETH circulating supply] - * [Price of ETHUSD] - / [Total crypto market cap (USD)] - -LINKDOM → [Total LINK circulating supply] - * [Price of LINKUSD] - / [Total crypto market cap (USD)] - -LTCDOM → [Total LTC circulating supply] - * [Price of LTCUSD] - / [Total crypto market cap (USD)] - -USDTDOM → [Total USDT circulating supply] - * [Price of USDTUSD] - / [Total crypto market cap (USD)] - -XRPDOM → [Total XRP circulating supply] - * [Price of XRPUSD] - / [Total crypto market cap (USD)] -``` - -# MOTIVATION - -The DVM currently does not support the listed dominance indices. Synthetic tokens which track market dominance could be used as hedging tools in one’s portfolio. These synthetic tokens can also be used as tools to speculate on a cryptocurrency's market share relative to all other cryptocurrencies. - -1. What are the financial positions enabled by creating this synthetic that do not already exist? - - - These synthetic tokens will enable users to enter into financial positions based on a particular coins market dominance. Previously, our team created an instrument on UMA to be able take positions on the, - - (i) relative market cap of Bitcoin (BTCDOM), as well as, - - (ii) all alt-coins against Bitcoin (ALTDOM). - - These new price identifiers allow users to take positions to long or short the relative market cap of these top 9 crypocurrencies. - - More importantly, not all these underlying cryptocurrencies are available to be traded on Ethereum. - -2. Please provide an example of a person interacting with a contract that uses this price identifier. - - - A user wanting to short a particular cryptocurrency's market dominance can mint synthetics and then market sell them. - - A user wanting to long a particular cryptocurrency's market dominance can market buy a synthetic token. - -

For example, a market dominance of 12.34% is represented as the value -> raw decimal value of `12.34` and will be represented on-chain as the raw value `12340000000000000000`. -> Appropriate scaling on-chain to 18 decimal places to "convert to wei" is applied as usual. - - - The index value is rounded to nearest 2 decimal places (third decimal place digit >= 5 rounds up and < 5 rounds down) - -
- -# RATIONALE - -Prices are primarily used in UMA to calculate a synthetic token’s value in case of liquidation or expiration. Contract counterparties, such as those running liquidation bots, also use the price index to ensure that sponsors are adequately collateralized. - -While coin domination can be succinctly represented as a single percentage, the underlying mechanisms for calculating it are quite involved and can dramatically differ by multiple percentage points from one data source to another. Calculating dominance involves knowing the current supply of a cryptocurrency, the prevailing market price of CRYPTOCURRENCY/USD, and the total market capitalization of all tokens in USD. More importantly, calculating the total market capitalization of all tokens in USD is a challenge since different data sources may altogether not include particular alt-coins thereby affecting all coin market dominance percentages. - -At the moment, market dominance is commonly referenced through three major sources: TradingView, CoinMarketCap & CoinGecko. However, unlike trading pairs which exhibit strong redundancy without deviation largely due to arbitrage incentives, each data source can vary by multiple percentage points due to differing calculation methodologies. Namely, each site has different methodologies for which alt-coins to admit into the total market cap, and a given coin’s market price and total coin circulation amounts may differ, compounding over hundreds or even thousands of alt-coins. Additionally, on a technical note, live and historical data update frequency varies and historical data may be paywalled, making it significantly harder to successfully run liquidation and dispute bots with redundancy and without paying for API access. To make matters worse, had we proposed a scheme where multiple data sources were used, we’d have to decide on using either the median or mean of the data sources and then have to specify some logic to handle if one of the data sources went down or starting to significantly different from the rest, for example. - -In an effort to alleviate these challenges, the Domination Finance team was able to get in touch with Bobby & TM, the co-founders of CoinGecko. The CoinGecko team went above and beyond to meet the requisites, updating CoinGecko’s coin dominance live data to 1-3 minute intervals from what was previously 10 minutes. Although this may introduce a single point of failure, we felt that the costs in increased complexity and mental load on the stakeholders who need to use it (like speculators, sponsors, liquidators & disputers) outweighed the benefits, especially during this period where the synthetic token is newly launched. - -While CoinGecko was able to provide the higher time granularity for coin dominance on short notice, historical data, necessary for dispute bots and voters, was unable to be immediately supplied from CoinGecko. Instead, constructing a separate caching service was necessary to track and record the historical data via polling CoinGecko's Live API to be able to compute historical coin dominance at a given point in time. Our caching API is more than sufficient to provide the historical data for dispute bots and voters. - -Initially, during normal operation, market dominance indices should closely track the value on CoinGecko. As more data sources for market dominance data are created and examined, voters are encouraged to add additional sources of information into the methodology for the price calculation. CoinGecko's full methodology for calculating dominance indices is detailed [here](https://www.coingecko.com/en/methodology). - -
- -# IMPLEMENTATION - -1. **What prices should be queried for and from which markets?** - - - The applicable price market dominance index should be queried depending on the cryptocurrency of interest. The current chosen method is to query for dominance indices from the Domination Finance API, which simply caches CoinGecko dominance data. - -2. **Pricing interval** - - - 1 min (round down relative to UTC) - -3. **Input processing** - - - None. - -4. **Result processing** - - - See rounding rules in *Technical Specification*. - - -For all price requests, voters should ensure that the calculated price does not differ greatly from broad market consensus. This is meant to be vague as the $UMA tokenholders are responsible for defining broad market consensus. This is especially important when relying on a third-party caching API; one possible way to verify this would be to query from the less granular CoinGecko API and compare results against those returned by Domination Finance API. - -
- -# Security considerations - -The current implementation relies on CoinGecko's and the Domination Finance's API endpoints to be able to receive accurate pricing information. Since calculating market dominance is an involved process with a number of variables at play, the trade-off is made to have a stable formulation from a single source instead of multiple sources which have widely varying calculation methodologies and public data availability. - -In the unlikely event that market index values returned from data sources are extreme outliers or erroneous compared to current market consensus, $UMA-holders may choose to use prevailing market consensus or using a nearby timestamp value instead. - -Anyone deploying a new priceless token contract referencing these identifiers should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for these identifiers and also contemplate de-registering these identifiers if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness is necessary to prevent market manipulation. diff --git a/research/uma/umips/UMIPs/umip-7.md b/research/uma/umips/UMIPs/umip-7.md deleted file mode 100644 index 5f1624de..00000000 --- a/research/uma/umips/UMIPs/umip-7.md +++ /dev/null @@ -1,85 +0,0 @@ -# Disclaimer - -The USDBTC price identifier has been deprecated.

Repeated analysis showed these same exchanges have the highest reputable volume for BTCUSD. - -Binance and Coinbase are both USD pairs, and Bitstamp is an USDT pair. Including any Tether pair means the prices could change due to the price of Tether. However, we decided that these two factors sufficiently mitigate this risk: the purpose of the DVM is to give token holders leeway to evaluate events, such as this, and adjust the price response accordingly. This is adequately captured by the language "determining whether that median differs from broad market consensus." Second, the USDT price could only have the effect of pulling the median towards the higher or lower of the 2 USD pairs, or it could fall right in between them. For this reason we believe the USDT concern is sufficiently handled - -We also considered an alternative set of exchanges.

First, the token acts as a governance token which allows community members (Citizens) to vote on important topics and decisions. Second, the XIO token acts as a redemption mechanism for future Blockzero assets. Holding XIO gives users the ability to access and claim alternative tokens. In the future, the XIO token will also be the primary governance token for the Blockzero Index (Treasury). - -Our team comprises over 22 core members, and we boast a wider community of over 8,000 dedicated community members we call “Citizens.” We take pride in being one of the most open and transparent communities in crypto, as evidenced by our regular Youtube livestreams, AMAs and open discussions, and high-quality engagement across our Social Forum and Telegram channels. - -We are dedicated to consistent innovation and ideation within the DeFi space, and future projects may encompass the likes of: a deflationary DEX, DeFi insurance, tokenized yield swaps, and the creation of a Blockzero Index (Treasury).

The ethVIX index is very similar to the Cboe VIX which tracks the expected volatility of the S&P 500. By trading ethVIX or iethVIX traders can take long or short positions against volatility, either as a speculative trade itself or a hedge for other speculative trades. - -Here are some examples of how traders might use ethVIX and iethVIX: -- In early March of 2020, 0xAlice believes that the global pandemic will greatly affect the price of ETH but she’s not sure if it will drop like the stock market or go up as a safe haven asset. She buys ethVIX for roughly 80 USDC per token. On Black Thursday (March 12th, 2020), the price of ETH drops significantly and the price of ethVIX moves to around 280 USDC. At expiration, 0xAlice redeems her ethVIX tokens while the price feed is still over 200 USDC. - -- In March of 2021, the price of ETH goes up quickly in a bull market.

Unlike other measures of volatility, the ethVIX (and VIX) use a model-free market based approach. Using a model-free approach gives the best calculation of expected future volatility. -Currently ethVIX is calculated by using out-of-the-money (OTM) call and put options from Deribit. This choice was made because Deribit’s market currently consists of roughly 80-90% of all ETH options volume. - -Manipulating the bids/asks on Deribit is the main vector of attack for changing the ethVIX price. Two things help to mitigate this attack. First, placing bids/asks that are not aligned with the market can be costly to an attacker if they are filled. Second, in certain cases when bids/asks become extremely skewed from their expected market prices, the price feeds use Deribit’s mark price instead of the bid/ask. -You can learn more about the approach used to calculate ethVIX in the [methodology paper](https://dvix.io/ethVIX_methodology.pdf). - -The settlement price calculation and the standard price request calculation are the same for both the ethVIX and iethVIX.

For example, in the sample data `1280` (`B25`) is the first strike below `1329.82` (`D148`). - - `E152` - The first strike price less than or equal to cell `D152` in the series `B83`-`B139`. For example, in the sample data `1280` (`B87`) is the first strike below `1332.04` (`D152`). - -# Security considerations - -Adding these new price identifiers pose certain risks: - -- Currently the options chain data used is from a centralized source (i.e. Deribit). -- Manipulation can occur on Deribit’s ETH options markets. As outlined previously this is mitigated in two ways: - - It will be expensive if the attacker’s orders are filled. - - In cases where prices are greatly misaligned with expected market prices the price feeds use the mark price instead of the bid/ask. -- To keep a 14-day average of volatility, the calculation rolls from one options expiry to another. This can lead to price swings but may also be a vector of attack. - - To mitigate this, we are launching weekly-expiring contracts after the next term rollover and having them expire before it occurs again. diff --git a/research/uma/umips/UMIPs/umip-75.md b/research/uma/umips/UMIPs/umip-75.md deleted file mode 100644 index f2dd5be7..00000000 --- a/research/uma/umips/UMIPs/umip-75.md +++ /dev/null @@ -1,53 +0,0 @@ -# Headers - -| UMIP-75 | | -| ---------- | ----------------------------------- | -| UMIP Title | Add bDigg as a collateral currency | -| Authors | Sean Brown (@smb2796) | -| Status | Approved | -| Created | April 7, 2021 | -| [Discourse](https://discourse.umaproject.org/t/add-bdigg-as-a-collateral-currency/854) | - -## Summary - -This UMIP will add bDigg, the BadgerDAO DIGG vault LP token, as an approved collateral currency. - -This will involve adding it to the whitelist and adding a flat final fee to charge per-request.

See below for a description of bDigg. - -- **bBadger** - - Digg tokens are staked in the Badger Sett Vault to mint bDigg token(s) - - View [here](https://etherscan.io/address/0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a) for the associated token address - - -bDigg as collateral is expected to have a variety of deployments. The timing for adding it now, and the immediate application, is for use with a USD/bDiggwhich will enable the creation of another type of Badger Dollar, a yield dollar token. - -**Note** - 'b' tokens are implemented as upgradeable proxy contracts. All governance functions are currently controlled via a multisig by the core Badger Team. - -## Technical Specification - -To accomplish this upgrade, the following changes need to be made: - -- The bDigg address, 0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a, needs to be added to the collateral currency whitelist -- A final fee of 0.016 needs to be added in the Store contract (~$400 at time of writing) - -## Rationale - -With $20m in illiquid Digg assets locked in the Digg vault, the ability to use these as collateral to borrow Badger Dollars reopens the possibilities of participating in open finance. In combination with the bDigg/USD price identifier which is also being proposed, bDigg could be used to create call options on the bDigg token price. - -## Implementation - -This change has no implementation other than the aforementioned governor transactions. - -## Security considerations - -Digg is an elastic supply rebasing token that is intended to track the price of Bitcoin by adjusting the supply of Digg. Because of the rebasing mechanism, the price of Digg (and bDigg) can be prone to large amounts of volatility. The bDigg supply is not elastic in the same way as DIGG. - -To read more about this, view the Digg explainer [here](https://badger.finance/digg). Contract deployers and users should take care to adjust contract parameteriziation and usage to account for the potential volatility. diff --git a/research/uma/umips/UMIPs/umip-76.md b/research/uma/umips/UMIPs/umip-76.md deleted file mode 100644 index 0e960b3e..00000000 --- a/research/uma/umips/UMIPs/umip-76.md +++ /dev/null @@ -1,165 +0,0 @@ -## HEADERS -| UMIP-76 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add bBadger/USD, [bwBTC/ETH SLP]/USD, bDiggUSD and USDbDigg as supported price identifiers | -| Authors | Sean Brown (smb2796) -| Status | Approved | -| Created | April 7th, 2021 -| [Discourse](https://discourse.umaproject.org/t/add-bbadger-usd-bwbtc-eth-slp-usd-bdigg-usd-and-usd-bdigg-as-supported-price-identifiers/856) | - -# SUMMARY - -The DVM should support price requests for the below price indexes: -- bBadger/USD -- [bwBTC/ETH SLP]/USD -- bDiggUSD -- USDbDigg - -# MOTIVATION - -The DVM currently does not support requests for these price identifiers. - -Most of the motivation behind this proposal is the same as what was proposed in [UMIP-39](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-39.md). UMIP-39 only the USD/bBadger and USD-[bwBTC/ETH SLP] price identifiers were proposed. These were intended to be used to create Badger dollars, yield dollars that are backed by Badger vault tokens.

Each wrapped token has a pricePerFullShare, which is the amount of underlying tokens that 1 b token could be redeemed for through the withdraw function. This underlying token can have different ways to determine its value depending on what type of token it is. - -The price per full share can be found by querying the contract of the token with `getPricePerFullShare` as seen in method 9 on this [contract](https://etherscan.io/address/0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a#readProxyContract). - -getPricePerFullShare is a pure view logic function in which no one has any authority to manipulate: - -``` -if (totalSupply() == 0) -{ - return 1e18; -} -return balance().mul(1e18).div(totalSupply()); -``` - -This returns the value of the balance of the vault divided by the number of shares to give the user the value of 1 share of the vault token. balance() represents the total balance of the underlying token in the vault. For example, if a user has 1 bDigg, this could be worth 1.2 Digg (which would be the ratio of balance / totalSupply). - -For bDigg you could use the same getPricePerFullShare method (described above) from the contract to get the underlying amount, and then the underlying values can be queried to give the price of one bDigg token in USD. - -## bBadger/USD - -The bBadger/USD pricing implementation will follow the same method that is laid out in [UMIP-39](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-39.md#usdbbadger-1) for USD/bBadger. The one difference will be to not take the inverse of USD/bBadger in step 8 and instead the result of step 7 should be rounded to 18 decimals to get the price of bBadger/USD. - -## [bwBTC/ETH SLP]/USD - -The bBadger/USD pricing implementation will follow the same method that is laid out in [UMIP-39](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-39.md#usd-bwbtceth-slp-1) for USD-[bwBTC/ETH SLP]. The one difference will be to not take the inverse of step 8 [bwBTC/ETH SLP]/USD in step 10 and instead round the result of step 9 to 18 decimals to get the [bwBTC/ETH SLP]/USD price. - -## bDiggUSD & USDbDigg - -To get the price of bDiggUSD perform the following steps. - -1. Query the getPricePerFullShare method on contract [0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a](https://etherscan.io/address/0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a). This information is on-chain and can be queried in any way that a voter wishes at the price request block. -2. Gather the price of DIGGUSD by following the directions detailed in [UMIP-61](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-61.md). -3. Multiply bDigg/Digg by Digg/USD and round to 18 decimals to get the bDiggUSD price. -4. Take the inverse of the unrounded bDiggUSD result (1/(bDiggUSD)) to get the price of USDbDigg. This price should then be rounded to 18 decimals. - -# Security considerations - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. - -Although these are "wrapped" tokens, an objective value of the underlying collateral can be accurately determined to adequately inform both participating liquidators and disputers. - -The value of collateral can be objective in terms of price per full share * underlying asset value. - -If the vault was hacked in a way that drained funds, the price per full share would decrease in a way that makes the collateral "proportionally recoverable" for all users. There is also insurance from Nexus mutual to consider in terms of valuing the asset in the event of a covered vulnerability - -For context, the wrapping mechanism mints a token that represents a % share of a liquidity pool or vault. This is common practice when providing liquidity to an AMM or depositing into a yield optimizer. Using identifiers like price per full share, an oracle can deterministically calculate the value of what the unwrapped ERC20 tokens would be worth at any given time. - -Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. $UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-77.md b/research/uma/umips/UMIPs/umip-77.md deleted file mode 100644 index 9c5171f9..00000000 --- a/research/uma/umips/UMIPs/umip-77.md +++ /dev/null @@ -1,159 +0,0 @@ -## Headers -| UMIP-77 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add yUSD, RAI, COMP, YFI, ALCX, ALPHA, MKR, CRV, REN, RGT, and NFTX as approved collateral currencies | -| Authors | Deepanshu Hooda (deepanshuhooda2000@gmail.com), John Shutt (john@umaproject.org) | -| Status | Approved | -| Created | April 7, 2021 | -| [Discourse Link](https://discourse.umaproject.org/t/add-usdt-yusd-ust-susd-comp-yfi-alcx-rune-alpha-mkr-crv-ren-rgt-nftx-and-ruler-as-approved-collateral-currencies/712/2) | | - -# Summary (2-5 sentences) -This UMIP will add yUSD, COMP, YFI, ALCX, ALPHA, MKR, CRV, REN, RGT, and NFTX as approved collateral currencies.

The type of price that the DVM will return is dependent on the timestamp the price request is made at. This timestamp is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the closing index value of uSTONKS calculation is used at expiry. This is very similar to the uGAS token and this design is outlined in [UMIP 22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md). - -Because the uSTONKS index value is only used at expiry, it will not be possible for a token sponsor to become undercollateralized based upon its movement. This means that only the Uniswap TWAP will need to be queried in real-time with a price feed. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. - -## TECHNICAL SPECIFICATIONS -- Price Identifier Name: uSTONKS_JUN21 -- Base Currency: uSTONKS_JUN21 -- Quote currency: None. This is an index, but will be used with USDC. -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE -The uSTONKS token is an expiring token that settles at the end of the expiry month using the final exchange closing prices on the last business day of the month for the ten stocks in the basket. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because uSTONKS is a decentralized synthetic that trades continuously 24/7 whereas the underlying stocks in the uSTONKS index trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. Using price feeds from the exchanges to monitor collateral ratios of token sponsors could be problematic outside of market hours especially if there is significant news released or general macro market forces. Though some stocks are traded after hours, the ability to extract this price data is difficult and the frequency may not be consistent across all ten stocks. Therefore, using the uSTONKS token price itself to monitor collateral ratios is a much better alternative as it should reflect the actual price movements during exchange hours and also reflect expectations of price movements after market hours. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -The stocks chosen represent the stocks with the highest average comment volume on r/WallStreetBets. This index was picked on April 14th, 2021 using r/WallStreetBets comment analysis from swaggystocks.com, and will remain static throughout the life of the price identifier. - -## IMPLEMENTATION -Voters should determine which pricing implementation to use depending on when the price request was submitted. - -**At Expiry** - -If the price request's UTC timestamp is at 1625097600 (July 1, 2021 00:00:00 UTC), a price request for uSTONKS for a given timestamp should be determined by performing the `At Expiry` process. - -To create a baseline for the uSTONKS index, a base price for each stock was chosen. These prices are the closing prices of each on 04/14/2021 and can be used by voters as reference values for their calculations. Voters are highly encouraged to verify these values themselves. This basket is static - it will not change over the life of the contract. - -| Ticker | Stock Price 04/14/2021 | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| TSLA | 732.23 | -| PLTR | 23.70 | -| GME | 166.53 | -| AAPL | 132.03 | -| COIN | 328.28 | -| RIOT | 50.16 | -| SQ | 258.40 | -| MVIS | 12.34 | -| RBLX | 75.35 | -| MARA | 42.97 | - -Each stock also is assigned an index value base. The index is equally weighted, so each stock is assigned a base of 10. This means that on 04/14/2021 at close, the uSTONKS index would have been worth 100 with every component making up 1/10th of that index. - -To calculate the uSTONKS price, an UMA voter should: -1. Query for the close price of one component on June 30, 2021. It is recommended that voters use the Google Sheets GOOGLEFINANCE function. -2. Divide the June 30 price by the base price and multiply by the index value base (10) to get today’s index value. -3. Perform this function for each component in the index and sum all of the results together. -4. Round the result of step three to six decimal places - -An example of this calculation is shown in [this](https://docs.google.com/spreadsheets/d/1kccQQJ8FqSnaDbeK4ljXERIg9lKkErHXtvGSbPcDTAw/edit?usp=sharing) Google Sheet. - -It is possible that, over the life of this price identifier, certain situations could arise that would affect the validity of the index calculation. Guidance is provided below for certain situations, but voters are free to come to an alternative consensus if a flaw in the methodology is identified or an unforeseen event occurs. - -1. In the case of a stock split, the base price of the stock should be divided by the number of shares that the stock is being split into. As an example - if TSLA issued a 4:1 stock split, the base price of TSLA, 732.23, would be divided by 4 and the new base index price would be 183.06. -2. In the case of a stock consolidation, the process is the same as for a stock split, except the base price should be multiplied by the number of shares being consolidated. - -**Before Expiry** - -If the price request's UTC timestamp is less than 1625097600 (July 1, 2021 00:00:00 UTC), voters will need to calculate a 2-hour TWAP for the uSTONKS_JUN21 token’s price in USDC. The following process should be used to calculate the TWAP. -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the uSTONKS_JUN21 / USDC pool returns in the latest block where the block timestamp is <= the price request timestamp. This is the price of 1 uSTONKS_JUN21 token in USDC. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. This results should be rounded to 6 decimals. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -## Security Considerations -Security considerations are focused on the use of the token price for monitoring collateral ratios. -- Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -- Mismatch between TWAP and gap higher in token price - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uSTONKS_APR21, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -Security considerations, like the ones above, have been contemplated and addressed, but there is potential for security holes to emerge due to the novelty of this price identifier. - -Additionally, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Contract deployers should also ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier or editing its implementation if security holes are identified. diff --git a/research/uma/umips/UMIPs/umip-8.md b/research/uma/umips/UMIPs/umip-8.md deleted file mode 100644 index 86ef5b4a..00000000 --- a/research/uma/umips/UMIPs/umip-8.md +++ /dev/null @@ -1,36 +0,0 @@ -## Headers -| UMIP-8 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add Global Collateral Currency Whitelist | -| Authors | Matt Rice (matt@umaproject.org), Clayton Roche (clayton@umaproject.org) | -| Status | Approved | -| Created | July 16, 2020 | - -## Summary (2-5 sentences) -This UMIP will have the effect of introducing a new global whitelist contract that will allow new collateral currencies to be added without deploying any new contracts.

This value should not be scaled and should be returned exactly as is. - -When the simple example ancillary data dictionary "constant:2" is stored as bytes, the result would be: 0x636f6e7374616e743a32. - -# RATIONALE -No rationale is needed. The motivation for this price identifier is explained in `motivation` and there is no plausible alternative for how to return a constant value. - -# IMPLEMENTATION - -1. Query for the `ancillaryData` value from the price request. -2. Decode the ancillary data from bytes to UTF-8. -3. If no ancillary data is provided, or there is ancillary data but it cannot be converted to the format in `Technical Specifications`, return `1`. -4. If the ancillary data in UTF-8 contains a `constant` key, return the `constant` value. Voters should disregard any other key:value pairs included in the ancillary data. - -# SECURITY CONSIDERATIONS - -Adding this price identifier poses no risk to the UMA system. Since there should be no inconsistency in the result that should be returned, there is no risk of lack of determinism in this approach, as long as the price requester specifies their ancillary data correctly. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-84.md b/research/uma/umips/UMIPs/umip-84.md deleted file mode 100644 index 19b457c4..00000000 --- a/research/uma/umips/UMIPs/umip-84.md +++ /dev/null @@ -1,245 +0,0 @@ -## Headers - -| UMIP-84 | | -| ------------------- | ------------------------------------------------------------------------- | -| UMIP Title | Add PUNKETH and PUNKETH_TWAP as price identifiers | -| Authors | Kevin Chan (kevin@umaproject.org), Chase Coleman (chase@umaproject.org) | -| Status | Approved | -| Created | April 19, 2021 | -| Discourse Link | https://discourse.umaproject.org/t/cryptopunks-index/933 | - - -# Summary - -This UMIP introduces two new price identifiers for a token referred to as `uPUNK`.

This originality has lead to them being highly valued and having consistent enough trade volume. -* _30 day median_: The 30 day median allows for the index to reflect common trading prices across many CryptoPunks rather than to respond to particular transactions -* _Unique CryptoPunks_: We only use the most recent trade price for each CryptoPunk. This is a security feature since if we used each transaction then a single person could trade one CryptoPunk amongst accounts they owned to manipulate the price. -* _Median rather than the mean_: Calculating the mean incorporates the price of every single transaction which means that someone who owned a single CryptoPunk could have a small effect on the price. The median can still be manipulated but, given the uniqueness restriction above, it would require someone to own enough CryptoPunks to make up half of the monthly transactions. - -The `PUNKETH_TWAP` price is necessary to support a market in which people may disagree about the fundamental value of the asset going forward. At expiry, there is a clear way to value the `uPUNK`, i.e., the `PUNKETH` price, however, the value of uPUNK prior to that seems less obvious and we'd like to let the markets price the asset. - -This self-referential component was also used in uGAS, see [UMIP 22](./umip-22.md) and has proven successful in that context. - - -# Implementation - -### PUNKETH - -When a price request is made, the following process should be followed: - -1. Retrieve all CryptoPunk `PunkBought` events from the 30 days prior to expiration -2. Identify the last price that each CryptoPunk was traded at using the event data -- Only one price should be produced per CryptoPunk even if they had traded multiple times. Due to a [bug in the CryptoPunk Market](https://github.com/UMAprotocol/UMIPs/pull/261#discussion_r622282931), this isn't as straightforward as reading the most recent value from the `PunkBought` event. The process we use is: - - Scan through all of the `PunkBought` events and identify the function call that generated the `PunkBought` event: - - If it was generated by `buyPunk` then use the `PunkBought.value` price - - If it was generated by `acceptBidForPunk` then we load all of the `PunkBidEntered` for that particular CryptoPunk and use the most recent bid (only one bid can be outstanding at a time and is always the highest) -3. Take the median of these prices - If there is an even number of prices, take the mean of the two values closest to the median. -4. Divide by 1000, and then round to 6 decimals to arrive at the final price. - - -**Example** - -If the timestamp requested was `1619222400` then: - -* We would need to identify all `PunkBought` events from `1619222400 - 30 days -> 1616630400` to `1619222400` -* Imagine that we had 5 `PunkBought` events with (`ts`, `punk_id`, `eth`) pairs of `[(1616630450, 1000, 20), (1616631450, 5000, 30), (1616631550, 5000, 35), (1618631550, 6000, 22), (1618632550, 9999, 15)]`. -* We would need to check what function generated each `PunkBought` event. Suppose they were all generated by `buyPunk`, then the prices we would use to compute the median would be `[20, 35, 22, 15]` -* There are an even number of values, so there's no "median value" in the data -- Thus we find the number between the two values closest to the median `[20, 22]` to get a price of `21` -* Divide by `1000` to get a price of `0.021` - -### PUNKETH_TWAP - -When a price request that relies on this price identifier is made, the following process should be followed: - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp - TWAP period (2 hours). -3. A single Uniswap price is defined for each timestamp as the price that the ETH/uPUNK ppool returns at the end of the latest block whose timestamp is less than or equal to the timestamp that is queried for. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will receive equal weight. -5. The final price should be returned with ETH - - -**Example** - -If the timestamp requested was `1619222400` then: - -* The end TWAP timestamp would be `1619222400` -* The start TWAP timestamp would be `1619222400 - 7200` -> `1619215200` -* The Uniswap price would be found for \{`1619215200`, `1619215201`, `1619215202`, ..., `1619222400`\} -* Average the prices corresponding with each price and then report this average - - -# Security Considerations - -### PUNKETH - -One of the main concerns is that someone with sufficient CryptoPunks chooses to manipulate the price. - -For example, there are accounts that own about 400 unique CryptoPunks and the unique number of CryptoPunks that traded in the last 30 days is about 600. An individual who owns 400 CryptoPunks and traded them amongst their own accounts at prices near zero could corrupt the price by driving it to zero after having minted and sold the tokens at a high price. - -One benefit to using an oracle with human intervention is that voters could recognize this type of price manipulation and there are other viable proxies for the expected price of a CryptoPunk.

If there were only 1-2 trades happening every 30 days, this index becomes much less useful because there's less information contained in its price. - -### PUNKETH_TWAP - -The main concerns of the TWAP price are: - -1. **Token price manipulation**: If the Uniswap pool is not sufficiently liquid, then attackers could try to drive down the Uniswap price and withdraw more collateral than intended. Most DeFi attacks have been done using flash loans, but flash loans would be ineffective since the price is measured at the end of each block. Collateralizaton based on the TWAP price would make it more capital intensive (and thus risky) to target the token price in this way. -2. **TWAP mismatch**: If the price of the token rises quickly then there would become a mismatch between the market price and the TWAP price. This might allow sponsers to mint tokens with less collateral than what they could sell them for on the market. Reasonable levels of collateralizaton requirements and the 2 hour "liveness period" help combat this concern. - -Both of these concerns are originally discussed in [UMIP 22](./umip-22.md) diff --git a/research/uma/umips/UMIPs/umip-85.md b/research/uma/umips/UMIPs/umip-85.md deleted file mode 100644 index 9ac0b6ec..00000000 --- a/research/uma/umips/UMIPs/umip-85.md +++ /dev/null @@ -1,301 +0,0 @@ -## HEADERS - -| UMIP-85 | | -| ----------------- | ----------------------------------------------------------------------------------------------- | -| UMIP Title | Add R3_10H_TWAP and R3_30D_GM as supported price identifiers | -| Authors | Ashutosh Varma (ashutoshvarma11@live.com) | -| Status | Approved | -| Created | April 1, 2021 | -| Link to Discourse | [LINK](https://discourse.umaproject.org/t/add-rai-redemption-rate-apr-as-price-identifiers/624) | - -# SUMMARY - -This UMIP will reference a synthetic token to be created with this price identifier. -This token will be referred to as 'R3' (Rai Redemption Rate) and will represent the token that tracks these identifiers. - -The DVM should support price requests for the R3_10H_TWAP and R3_30D_GM price indices. - -The DVM should support requests for a price that resolves to either the 30 day geometric mean (R3_30D_GM) or -a 10-hour Time-Weighted Average Price (R3_10H_TWAP) of RAI redemption rate coefficient APR. - -The price resolution method to use will depend on the timestamp the price request was made at. - -For a price request made at or after the expiry timestamp, the price will be resolved with the R3_30D_GM, -30 day geometric mean of redemption rate coefficient APR calculation defined as per R3 token Technical Specification. - -For a price request made before the expiry timestamp, the price will be resolved to R3_10H_TWAP, a 10-hour TWAP of -redemption rate coefficient APR. - -# MOTIVATION - -The DVM currently does not support reporting 30 day geometric mean or 10-hr TWAP of RAI redemption rate coefficient APR. - -1.

The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (10 hours in this case). -3. A single redemption rate coefficient APR value (RR) is defined for each timestamp as the price that the subgraph - returns at the end of the latest block whose timestamp is <= the timestamp that is queried for. -4. The TWAP is a time weighted average of the rates for each timestamp between the start and end timestamps. - Each price in this average will get weight equal to its time period (TI). TWAP will be calculated as ∑(RR * TI) / TT -5. As the values from subgraph are integers, so it should be left as returned without any scaling transformation. -6.

- -# Security considerations - -Security considerations are focused on the use of the redemption rate for monitoring collateral ratios. - -- **Intentional Liquidation** - Since RAI dampen the ETH movement, any changes in ETH price are reflected shortly in RAI in form of - change in redemption rate. Therefore an attacker could use this to cause intentional liquidations. - Assume ETH price shoots up and R3 market price double in anticipation of increase in redemption rate. - Now the attacker can mint the synths at considerably lower price and sell them to market at higher price which - can result in intentional liquidations if his/her profit is higher than collateral locked. - However it is important ot note that the current Expiring Multi Party (EMP) the contract requires sponsors to - mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200%. - Therefore assuming the GCR is similar for R3 and additionally setting the minimum CR to 200% or above should prevent intentional liquidations.

The relationship between FARM and iFARM is governed by the exchange rate in the iFARM contract which increases over time in relation to the amount of FARM distributed in the profit share vault. - -Supporting the iFARMUSD and USDiFARM price identifiers would enable the collateralization of iFARM to borrow against iFARM and use that associated credit to purchase other cryptocurrencies. It enables token stakers to leverage their vaulted positions in iFARM. This would allow Alice to use 10 iFARM (worth $2860 for example if FARM price is $286 and her iFARM has not yet appreciated) to create 800 USD synth tokens (worth $800). At expiry, Alice could redeem her 800 USD synthetic tokens for the USD amount of iFARM the USD synthetic tokens are worth. Once this is complete, she could then withdrawal the rest of her collateral. - -# MARKETS & DATA SOURCES - - **Required questions** - -1. What markets should the price be queried from?

(Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges)** - -Uniswap has the vast majority of FARM volume and depth. These should be used over all other sources. - -**What is the potential for the price to be manipulated on the chosen exchanges?** - -iFARM is not a collateral currently on any loan services and the majority of the liquidity is locked into profit share vaults. The potential risk for this is low. - -**Should the prices have any processing (e.g., TWAP)?** - -Processing is defined in the implementation section. - -# IMPLEMENTATION - -iFARM is an interest bearing receipt representing a compounding amount of FARM deposited into the Harvest profit sharing pool. Each wrapped token has a pricePerFullShare, which is the amount of underlying FARM tokens that 1 iFARM could be redeemed for through the withdraw function. This underlying token can have different ways to determine its value depending on what type of token it is. - -The price per full share can be found by querying the contract of the token with `getPricePerFullShare` as seen in method 9 on this [contract](https://etherscan.io/address/0x1571eD0bed4D987fe2b498DdBaE7DFA19519F651#readProxyContract). - -getPricePerFullShare is a pure view logic function in which no one has any authority to manipulate. The reference code cited above returns this value in in a data.csv file by block. - -This returns the value of the balance of the vault divided by the number of shares to give the user the value of 1 share of the vault token. balance() represents the total balance of the underlying token in the vault. For example, if a user has 1 iFARM, this could be worth 1.06 FARM (which would be the ratio of balance / totalSupply). - -For iFARM you could use the same getPricePerFullShare method (described above) from the contract to get the underlying amount of FARM, and then the underlying values can be queried to give the price of one FARM token in ETH. That in turn can be converted to USD by querying the ratio of ETH/USD using UMIP-6. - -For both implementions, a block number will need to be used. The block number should be the block that is closest to and before the timestamp that the price request timestamp. - -## Determining the iFARMUSD and USDiFARM prices - -**A. How should tokenholders arrive at the price in the case of a DVM price request?** - -To obtain the iFARMUSD price, follow this process.

To update the collateral currencies, one would need to deploy a new template. Expiries could only be at the beginning of the month, and all liveness periods had to be 2 hours. These parameter choices were made to keep the risks as low as possible as the first few EMPs were being deployed on mainnet. Now that there have been multiple successful deployments of the EMP contract, we propose that these parameters become more flexible to allow anyone to experiment with parameters of their choice. - -## Technical Specification -To accomplish this upgrade, a new financial contract template must be deployed: -- A modified `ExpiringMultiPartyCreator` contract will need to be deployed. The notable changes include: - - On each attempted deployment, this contract should query the `“CollateralWhitelist”` address using the `Finder` contract to find the whitelist address. Then it should verify that the provided collateral currency is on said whitelist. - - On each attempted deployment, this contract should allow any timestamp to be provided as the expiry. Note: the `ExpiringMultiParty` contract has a check that requires the timestamp to be in the future at deployment time. - - On each attempted deployment, this contract should allow the deployer to pass in the withdrawal and liquidation liveness, and it should check that they are both > 0. - - The EMP that is deployed by the creator will have minor changes in the events it produces detailed [here](https://github.com/UMAprotocol/protocol/pull/1753). - -After deployment, this new `ExpiringMutltiPartyCreator` contract should be approved as a ContractCreator in the Registry. - -Note: the voters only vote for the approval -- the deployment has no effect on the protocol until added as a ContractCreator. - -## Rationale - -Part of the rationale behind this change is that it’s simpler to deploy one `ExpiringMultiPartyCreator` contract that allows users to deploy almost any EMP parameterization than deploying an `ExpiringMultiPartyCreator` contract each time there’s a new use case. - -## Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/core/contracts/financial-templates/expiring-multiparty). The directory contains both the [implementation](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/expiring-multiparty/ExpiringMultiParty.sol) of the `ExpiringMultiParty` template and the [deployer contract](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/expiring-multiparty/ExpiringMultiPartyCreator.sol) that will be registered with the DVM to allow users to deploy their own `ExpiringMultiParty` contract. Note: the changes specified above are currently in progress, so the current version may not match the specification yet. - -The new `ExpiringMultiPartyCreator` contract changes since the previously approved version were implemented [here](https://github.com/UMAprotocol/protocol/pull/1746). Additionally, the minor event changes that were made to the `ExpiringMultiParty` contract are implemented [here](https://github.com/UMAprotocol/protocol/pull/1753). These are the only changes that have been made since the previous version of the `ExpiringMultiPartyCreator` was deployed and approved. - -## Security considerations -These changes *have not* been audited. However, the changes are deemed to be minor and an audit is expected to come soon after its addition to the system. This is deemed to be safe because no *stateful logic* has been changed in the `ExpiringMultiParty` and the `ExpiringMultiPartyCreator` changes only affect the possible parameterizations of the `ExpiringMultiParty` contracts that can be deployed. - -As before, anyone deploying a new priceless token contract should take care to parameterize the contract appropriately to avoid the loss of funds for users. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. Anyone planning to use a synthetic token (as a sponsor or tokenholder) should validate that the token is solvent and well-parameterized before using since there are configurations and states that make the proposed contract unsafe. - -These considerations should be taken more seriously now that there are fewer limitations on what parameters a deployer can specify for an EMP contract. diff --git a/research/uma/umips/UMIPs/umip-90.md b/research/uma/umips/UMIPs/umip-90.md deleted file mode 100644 index 4687fe4b..00000000 --- a/research/uma/umips/UMIPs/umip-90.md +++ /dev/null @@ -1,153 +0,0 @@ -## Headers -| UMIP-90 | | -|------------|----------------------------------------------------------| -| UMIP Title | Add NGNUSD, PHPUSD, CADUSD, ZARUSD, KRWUSD and JPYUSD as price identifiers | -| Authors | Vsevolod Potorocha (vsevolod@jarvis.network) | -| Status | Approved | -| Created | 30/04/2021 | -| Discourse link | https://discourse.umaproject.org/t/umip-90-ngn-php-cad-zar-krw-and-jpy-vs-usd/1033 - -## Summary -The DVM should support price requests for the NGNUSD, PHPUSD, CADUSD, ZARUSD, KRWUSD and JPYUSD price index. - -## Motivation -The DVM currently does not support these Forex price index. - -### Cost: -While Forex data are free through open centralized exchange, brokers, and other sources APIs, the most reliable are paid.

Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as a official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds.

There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes.

However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of JPYUSD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap on JPY/USD, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-91.md b/research/uma/umips/UMIPs/umip-91.md deleted file mode 100644 index 91158afc..00000000 --- a/research/uma/umips/UMIPs/umip-91.md +++ /dev/null @@ -1,1389 +0,0 @@ -## HEADERS -| UMIP-91 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add LONUSD, USDLON, BANKUSD, USDBANK, MASKUSD, USDMASK, VSPUSD, USDVSP, SFIUSD, USDSFI, DEXTFUSD, USDDEXTF, ORNUSD, USDORN, BONDUSD, USDBOND, PUNK-BASICUSD and USDPUNK-BASIC as price identifiers | -| Authors | John Shutt (john@umaproject.org), Deepanshu Hooda (deepanshuhooda2000@gmail.com) | -| Status | Approved | -| Created | April 29, 2021 -| Link to Discourse | [Link](https://discourse.umaproject.org/t/add-lonusd-usdlon-bankusd-usdbank-maskusd-usdmask-vspusd-usdvsp-sfiusd-usdsfi-fraxusd-usdfrax-dextffusd-usddextf-ornusd-usdorn-bondusd-usdbond-punk-basicusd-and-usdpunk-basic-as-price-identifiers/1036) - - -# SUMMARY - -The DVM should support price requests for the below price indices: -- LON/USD -- USD/LON -- BANK/USD -- USD/BANK -- MASK/USD -- USD/MASK -- VSP/USD -- USD/VSP -- SFI/USD -- USD/SFI -- DEXTF/USD -- USD/DEXTF -- ORN/USD -- USD/ORN -- BOND/USD -- USD/BOND -- PUNK-BASIC/USD -- USD/PUNK-BASIC - -The canonical identifiers should be `LONUSD`, `USDLON`, `BANKUSD`, `USDBANK`, `MASKUSD`, `USDMASK`, `VSPUSD`, `USDVSP`, `SFIUSD`, `USDSFI`, `DEXTFUSD`, `USDDEXTF`, `ORNUSD`, `USDORN`, `BONDUSD`, `USDBOND`, `PUNK-BASICUSD` and `USDPUNK-BASIC`. -# MOTIVATION - -1.

So, if a token has deep liquidity and high volume on Uniswap but little or no CEX activity, we would use a Uniswap TWAP. If a token has deep liquidity and high volume on two CEXs and Uniswap, we would take the median of the three prices (with a TWAP for Uniswap). - -# LON - -## MARKETS & DATA SOURCES - -**Required questions** - -Market: OKEx, Uniswap, SushiSwap - -* OKEx LON/USDT: https://api.cryptowat.ch/markets/okex/lonusdt/price -* SUSHISWAP LON/USDT: https://analytics.sushi.com/pairs/0x55d31f68975e446a40a2d02ffa4b0e1bfb233c2f -* UNISWAP LON/ETH: https://v2.info.uniswap.org/pair/0x7924a818013f39cf800f5589ff1f1f0def54f31f - - -How often is the provided price updated? - - - The lower bound on the price update frequency is a minute. - -Provide recommended endpoints to query for historical prices from each market listed. - -* OKEx: https://api.cryptowat.ch/markets/okex/lonusdt/ohlc?after=1617848822&before=1617848822&periods=60 - - -Do these sources allow for querying up to 74 hours of historical data? - - - Yes. - -How often is the provided price updated? - - - Every 60 seconds for CW.

- -# SUMMARY - -The DVM should support price requests for the [CRSP US Total Market TR Index](http://www.crsp.org/products/investment-products/crsp-us-total-market-index) (CRSPTMT), a highly diversified index that aims to track the US stock market as a whole. - -
- -# MOTIVATION - -UMA already counts with many price identifiers enabling the creation of derivatives on crypto assets and prices, as well as some identifiers for traditional, off-chain financial products like gold or stocks. However, access to highly diversified indices tracking large sectors of the economy are sorely lacking. Having exposure to broad indices could prove beneficial to people outside the US, as these products provide excellent risk-adjusted returns. In particular, they provide a relatively low risk strategy to beat USD inflation. - -The [Center for Research in Security Prices](http://www.crsp.org/products/documentation/crsp-indexes) (CRSP) is a data provider affiliated to the University of Chicago that maintains several such indices. Of all of them, the [US Total Market Total Return Index](http://www.crsp.org/products/investment-products/crsp-us-total-market-index) (CRSPTMT), is the most comprehensive and realistic metric of total US stock market performance, as it includes nearly all publicly traded US companies and it accounts for dividends. - -

Rounding** - The price shall be rounded to 6 decimal places using [round half down](https://en.wikipedia.org/wiki/Rounding#Round_half_down). - -
- -# RATIONALE - -A self-referential price before expiry avoids price drift when US markets are not trading (nights and weekends). This requires token sponsors to set an initial price; it is recommended they consult the Google Finance price when doing this, as they may be arbitraged otherwise. - -Short-lived price manipulation of an AMM is relatively cheap, but it becomes expensive over time as the position can be easily arbitraged. This motivates the introduction of TWAPs, in line with [Uniswap's recommendation for building price oracles](https://uniswap.org/docs/v2/smart-contract-integration/building-an-oracle/). - -
- -# IMPLEMENTATION - -The contract will expire at 16:00 EST on 2021/09/21. The corresponding POSIX timestamp is `1632254400`. To determine the price, the DVM will choose between the two protocols described below depending on the timestamp of the oracle request, `request_timestamp`. - -- If `request_timestamp >= 1632254400`, use the "After expiry" protocol. -- Otherwise, use the "Before expiry" protocol. - -## After expiry - -After expiry, the contract should be settled according to the close price of the index on 2021/09/21. This price will be obtained by calling the `GOOGLEFINANCE` function on Google Sheets with the following parameters: - -``` -=GOOGLEFINANCE("CRSPTMT", "close", DATE(2021, 5, 21)) -``` - -This query can be done without API keys and at no cost to the user. Although querying the price via Google Sheets is preferred, it can also be accessed using web interface provided by [Google Search](https://www.google.com/search?hl=en&q=CRSPTMT). - -## Before expiry - -Before expiry, the price will be determined by the on-chain secondary market. At any time, the price will be the 2h Time-Weighted Average Price (TWAP) of the Uniswap uCRSPTMT_SEP21/USDC pool with the largest liquidity. - -Voters should follow this protocol to determine the price: - -1. Find the uCRSPTMT_SEP21/USDC Uniswap pool with the largest liquidity. -2. Determine the price of uCRSPTMT_SEP21 in USD returned by the pool for every timestamp between the request timestamp minus 2 hours and the request timestamp, inclusive. -3. The price to return is the arithmetic mean of all the prices at each timestamp, rounded to 6 decimals as explained below. - -# Security considerations - -1. Where could manipulation occur? -If trading is not very liquid, the price could be temporarily manipulated before expiry by executing large trades on Uniswap. However, we note that sustaining the attack for the whole duration of a 2h TWAP would be too costly and probably not worth it. - -2. What are current or future concern possibilities with the way the price identifier is defined? -After expiry, the price ID relies on a single data source. If Google Finance was down at the time for whatever reason, this could delay contract settlement. diff --git a/research/uma/umips/UMIPs/umip-93.md b/research/uma/umips/UMIPs/umip-93.md deleted file mode 100644 index e80a8766..00000000 --- a/research/uma/umips/UMIPs/umip-93.md +++ /dev/null @@ -1,50 +0,0 @@ -| UMIP-93 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add yvUSDC as a whitelisted collateral currency | -| Authors | Pascal Tallarida (pascal@jarvis.network) | -| Status | Approved | -| Created | 09/05/2021 -| Discourse link | https://discourse.umaproject.org/t/add-yvusdc-as-approved-collateral/1060 | - -## Summary - -This UMIP will add yvUSDC, an interest-bearing stablecoin tokenizing USDC deposited in YEARN V2 Vaults, as approved collateral currency. This will involve adding the currency to the whitelist and adding a flat final fee to charge per-request.

Contract deployers would need to use the yvUSDC/USDC exchange rate. - -A potential added risk for liquidators is that the yvUSDC token can be obtained only by depositing USDC in Yearn V2 Vault system (currently there is not a secondary market for the token). In that case liquidators are exposed to a possible high gas costs, which might dissolve some of the profits from the liquidation itself. One way to mitigate this is to hold a reserve of yvUSDC, which allows generating yield while a liquidation opportunity arrises. diff --git a/research/uma/umips/UMIPs/umip-94.md b/research/uma/umips/UMIPs/umip-94.md deleted file mode 100644 index f9cb9370..00000000 --- a/research/uma/umips/UMIPs/umip-94.md +++ /dev/null @@ -1,57 +0,0 @@ -| UMIP-94 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add UST as a whitelisted collateral currency | -| Authors | Pascal Tallarida (pascal@jarvis.network) | -| Status | Approved | -| Created | 09/05/2021 -| Discourse link | https://discourse.umaproject.org/t/add-ust-as-approved-collateral/1059 | - -## Summary - -This UMIP will add TerraUSD (UST) as approved collateral currencies. This will involve adding the currencies to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 400 UST per request. - -## Motivation - -UST is a decentralized algorithmic stablecoin pegged to the US dollar, issued on the Terra blockchain and wrapped onto various Blockchain. - -UST has been launched in September 2020, following the success of TerraKRW (KRT), a stablecoin pegged to the Korean Won (KRW). Since launch, UST became the 5th largest stablecoin, right behdind DAI, with a $2 Bn market capitalisation. $360M of UST are currently circulating on the Ethereum Blockchain. - -Unlike other algorithmic stablecoin, UST has been incredibly stable. - -Terra USD(UST) uses an elastic supply to maintain its peg to the USD. As example when there is a high demand for UST and the stable coin is traded above 1 USD, the supply of UST will be increase by minting new UST, thus bringing back down the price to a dollar. Vice versa if there is a shortage in demand for UST, the protocol will buy back UST and will burn in, thus reducing the supply and pushing the price back up to be equal to 1 USD. Also arbitrage opportunities are an incentivization to keep the price at 1 USD. - -The above algorithmic approach is achieved by using LUNA token as collateral for UST. In order to mint a new supply of UST, the protocol will have to burn LUNA tokens. Vice versa if the supply of UST have to be reduced, the protocol will burn UST tokens and mint LUNA tokens. - -It is listed agasint USDT on Bittrex and Kucoin, and in the UST Curve meta-pool (UST+3pool). - -Adding UST as collateral will allow the creation of new synthetic assets backed by this stablecoin.

To construct the UMA/USD price feed, we will calculate the median price between the three data sources used in the UMIP 57: Coinbase (USD), Okex (USDT) and Binance (USDT). - -USD/XXX: TraderMade's APIs provides a free tier API to the price of USD agasint any currency (1,000 queries per month; the price update frequency is below 1 second for the live price, and 60 seconds for the historical price; it also provides subscription model for 30 pounds per month). Forex pair price should then be rounded to 5 decimals. - -#### Specification on historical prices: -- Cryptowatch and TraderMade use a different input format for querying historical data: you need to use Unix timestamp for Cryptowatch, and YYYY-MM-DD-HH:MM for TraderMade. -- Price requests should use the minute price that is nearest and earliest than the price request timestamp. Voters should use the open price of the OHLC period prior or undergoing based on the price request timestamp. Cryptowatch and TraderMade endpoints are queried based on the OHLC period's open time. For example, a request for a Forex pair price at 2021-05-10-21:10:16 should use query for the same period and use the open price as a reference. - -#### Weekend timestamp -Over the weekend or some official holidays the REST API for Forex pair prices does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). - -Due to unavailability of price feed for foreign exchange rates over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - - -## Technical Specification -The definition of this identifiers should be: - - -- Identifier name: EURUMA -- Base Currency: EUR -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: GBPUMA -- Base Currency: GBP -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: CHFUMA -- Base Currency: CHF -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: CADUMA -- Base Currency: CAD -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: JPYUMA -- Base Currency: JPY -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: ZARUMA -- Base Currency: ZAR -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: KRWUMA -- Base Currency: KRW -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: NGNUMA -- Base Currency: NGN -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: PHPUMA -- Base Currency: PHP -- Quote Currency: UMA - ------------------------------------------ - - -- Source: https://marketdata.tradermade.com and https://cryptowat.ch/ -- Result Pocessing: None -- Input Processing: None.

They are popular with Quantitative Traders, Fintech companies and Institutional customers who require a high quality and trusted feed. Although other price feeds can be used for forex pairs, we'd reccommend using TraderMade price feed. - -For collateral tokens price feed we'd reccommend using CryptoWatch, as it is the most widely used price feed currently on the market. CryptoWatch allows polling for price feeds from various exchanges, which allows getting a price feed even in the case where a certain exchange is in maintance or down due to technical reasons. Also the availability of multiple price feeds from various exchanges gives the opportunity to get a computed median price of a certain collateral token by comparing prices from various exchanges which mitigates the risk of a corrupted price feed. - -## Implementation -To construct UMA/XXX or XXX/UMA price feed, we need to combine two price feeds: -• To get UMA/XXX: we divide UMA/USD by XXX/USD, or multiply it by USD/XXX. -• To get XXX/UMA: we divide 1 by UMA/XXX. - -Note that the FX rate price feeds have already been implemented in UMIPs [29](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-29.md) and [90](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-90.md). The UMAUSD price identifier has already been implemented in [UMIP-57](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-57.md#price-feed-implementation-3). This UMIP simply combines price identifiers from those three UMIPS to arrive at the XX/UMA price identifiers. - -### Example: EURUMA and UMAEUR -- To construct the price for UMA/EUR we will multiply UMA/USD by USD/EUR. -- To construct the price of EUR/UMA we will divide 1 by UMA/EUR. - -#### Steps to construct the live prices: - -As a reference you can look at [UMIP-57](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-57.md) as the below described approach has the same implementation. - -Step 1: query prices for UMAUSD: -• Coinbase Pro UMA/USD: https://api.cryptowat.ch/markets/coinbase-pro/UMAUSD/price -• Binance UMA/USDT: https://api.cryptowat.ch/markets/binance/UMAUSDT/price -• OKEx UMA/USDT: https://api.cryptowat.ch/markets/okex/UMAUSDt/price - -Step 2: calculate the median price between the 3 prices - -Step 3: query prices for USD/EUR -• USD/EUR: https://marketdata.tradermade.com/api/v1/live?currency=USDEUR&api_key=api_key - -Step 4: multiply the median price of UMAUSD by USD/EUR to get UMA/EUR or divide 1 by UMA/EUR to get EUR/UMA. - -Step 5: Round the price based on the rounding defined in `Technical specifications` section. - -#### Steps to construct historical prices: -Step 1: query historical prices for UMAUSD for the 10th of May 2021 at 6:03pm: -• Coinbase Pro UMA/USD: https://api.cryptowat.ch/markets/coinbase-pro/UMAUSD/ohlc?after=1620669780&before=1620669780&periods=60 -• Binance UMA/USDT: https://api.cryptowat.ch/markets/binance/UMAUSDt/ohlc?after=1620669780&before=1620669780&periods=60 -• OKEx UMA/USDT: https://api.cryptowat.ch/markets/okex/UMAUSDt/ohlc?after=1620669780&before=1620669780&periods=60 - -Step 2: calculate the median price between these 3 prices. - -Step 3: query historical prices for USDEUR for the 10th of May 2021 at 6:03pm: -• USD/JPY: https://marketdata.tradermade.com/api/v1/minute_historical?currency=USDEUR&date_time=2021-05-10-18:03&api_key=apikey - -Step 4: multiply the median price of UMAUSD by USD/EUR to get UMA/EUR or divide 1 by UMA/EUR to get EUR/UMA. - -Step 5: Round the price based on the rounding defined in `Technical specifications` section. - - -To build UMAGBP prices, you just need to repeat these steps by changing USD/EUR by USD/GBP, etc. - - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds.

However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of JPY/USD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap on JPY/USD, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. \ No newline at end of file diff --git a/research/uma/umips/UMIPs/umip-96.md b/research/uma/umips/UMIPs/umip-96.md deleted file mode 100644 index 9959694d..00000000 --- a/research/uma/umips/UMIPs/umip-96.md +++ /dev/null @@ -1,287 +0,0 @@ -## Headers -| UMIP-96 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add BNT, vBNT, BAND, SDT, KP3R, CREAM, CHAIN, and ERN as approved collateral currencies | -| Authors | John Shutt (john@umaproject.org), Deepanshu Hooda (deepanshuhooda2000@gmail.com), Britt, Aaron (bitznbrewz), Shawn Hagenah (Hagz48) | -| Status | Approved | -| Created | May 2, 2021 | -| [Discourse Link](https://discourse.umaproject.org/t/add-band-sdt-kp3r-cream-lpool-chain-sand-ern-and-pols-as-approved-collateral-currencies/1054) | | - -# Summary (2-5 sentences) -This UMIP will add BNT, vBNT, BAND, SDT, KP3R, CREAM, CHAIN, and ERN as approved collateral currencies.

One of the promises of BNT's ICO was that investors in the coin would gain interest on the transaction fees as other crypto coins are converted into and out of BNT. - -Bancor's protocol converts between different ERC-20 compatible tokens. Each smart token is linked to smart contracts that hold reserves of other ERC-20 tokens. The tokens are converted internally based on these reserves and depending upon the volume of user requests. - -Essentially, smart tokens can be thought of as coins that hold the monetary value of other compatible virtual coins. It is the same in principle to a central bank that holds foreign currency reserves and converts between them as required. - -The Bancor protocol supports all virtual currency tokens that are compatible with the ERC-20 format. Any smart token created on the Bancor network is also ERC-20 compatible, and therefore compatible with other tokens on the network. - -### Security Considerations - -$UMA holders should evaluate the ongoing cost and benefit of supporting this asset as collateral and also contemplate removing support of this collateral if liquidity concerns are identified. UMA holders should take note of the collaterals changes, or if added to robustness (e.g. via TWAPs) are necessary to prevent market manipulation. - -BNT has a circulating supply of 194,685,628 BNT and a max supply of 194,685,628.

It will also introduce UMA to a large community interested in DeFi oracles, which may lead to more integrations with new products that would be well served by UMA's oracle design. - -### Token Summary - -Band protocol is a cross chain data oracle platform, that is able to take on real world data and supply it to on-chain applications, while also connecting to smart contracts to facilitate the exchange of information between on-chain and off-chain data sources. It was an Ethereum-native project but switched to Cosmos network in June 2020 and currently spans Ethereum, Cosmos, Binance, Polygon, and other ecosystems. - -### Security Considerations - -$UMA holders should evaluate the ongoing cost and benefit of supporting this asset as collateral and also contemplate removing support of this collateral if liquidity concerns are identified. UMA holders should take note of the collaterals changes, or if added to robustness(Eg. via TWAPs) are necessary to prevent market manipulation. - -An additional consideration is that on-chain liquidity for BAND is not particularly strong, with only $250,000 in liquidity in a Uniswap v2 pool and a nearly empty Uniswap v3 pool.

These assets need to expire shortly after they go live on the market, however the exact dates are always up in the air and often delayed or changed. Therefore we designed this implementation to have a smooth way of expiring prelaunch synthetic assets at the right time and price. - -An alternative design where the expiration would be set via UMA vote was considered.

Therefore the potential surface area for an exploit is low, particularly as we receive feedback from the community and UMA team. However, we may pursue an audit in the future. - -Per feedback from the UMA team we decided to use the Optimistic Oracle for the final price determination, so that the third party DAO address only has the authority to expire the contract but not determine the expiry price. - -We included the updateDAOAddress function to minimize potential issues with the application specific external DAO contract. However, the security of the DAO is important as the VEMP contract could be prematurely or belatedly expired. diff --git a/research/uma/umips/UPPs/upp-1.md b/research/uma/umips/UPPs/upp-1.md deleted file mode 100644 index 2a58a309..00000000 --- a/research/uma/umips/UPPs/upp-1.md +++ /dev/null @@ -1,27 +0,0 @@ -# UPPs - -UPPs (“UMA Parameter Proposals”) are a lighter-weight form of an UMIP meant for simple parameter changes, like fees, inflation rewards, voting reward expiries, etc. The difference between this and an UMIP is semantic and process-based.

This was a good balance between cost to users and preventing DVM spam at the time. After registering the Optimistic Oracle final fees are payable only when proposed prices are disputed, thus allowing to increase cost per DVM request. - -As there are more projects building on top of UMA potential amount of DVM requests is increasing. In order to reduce burden on DVM and incentivize price resolvement through Optimistic Oracle this UPP proposes increasing final fees to around $1500. - -Another factor considered was the minimum value of UMA holdings that would make spamming DVM profitable through inflationary voting rewards. During last couple of months median ratio of correct votes over snapshotted UMA supply was around 20%, hence each vote yielding 0.05% / 20% = 0.0025 or 0.25%. So in order to profit from spamming DVM at $1500 final fee value one should hold at least 1500 / 0.25% = $600'000 worth of UMA.

During last couple of months median ratio of correct votes over snapshotted UMA supply was around 20%, hence each vote yielding 0.05% / 20% = 0.0025 or 0.25%. So in order to profit from spamming DVM at $1500 final fee value one should hold at least 1500 / 0.25% = $600'000 worth of UMA.

This was a good balance between cost to users and preventing DVM spam at the time. After registering the Optimistic Oracle final fees are payable only when proposed prices are disputed, thus allowing to increase cost per DVM request. - -As there are more projects building on top of UMA potential amount of DVM requests is increasing. In order to reduce burden on DVM and incentivize price resolvement through Optimistic Oracle this UPP proposes increasing final fees to around $1500. - -Another factor considered was the minimum value of UMA holdings that would make spamming DVM profitable through inflationary voting rewards. During last couple of months median ratio of correct votes over snapshotted UMA supply was around 20%, hence each vote yielding 0.05% / 20% = 0.0025 or 0.25%. So in order to profit from spamming DVM at $1500 final fee value one should hold at least 1500 / 0.25% = $600'000 worth of UMA. It is assumed that larger UMA holders would keep a longer term view and resist to spam DVM for short term gains. - -## Specifics - -On Ethereum mainnet final fees in the Store contract should be set to: -* XIO: [0x0f7f961648ae6db43c75663ac7e5414eb79b5704](https://etherscan.io/address/0x0f7f961648ae6db43c75663ac7e5414eb79b5704): 8400 -* BAL: [0xba100000625a3754423978a60c9317c58a424e3d](https://etherscan.io/address/0xba100000625a3754423978a60c9317c58a424e3d): 75 -* bDIGG: [0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a](https://etherscan.io/address/0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a): 0.15 -* yUSD: [0x5dbcf33d8c2e976c6b560249878e6f1491bca25c](https://etherscan.io/address/0x5dbcf33d8c2e976c6b560249878e6f1491bca25c): 1130 -* COMP: [0xc00e94cb662c3520282e6f5717214004a7f26888](https://etherscan.io/address/0xc00e94cb662c3520282e6f5717214004a7f26888): 5 -* YFI: [0x0bc529c00c6401aef6d220be8c6ea1667f6ad93e](https://etherscan.io/address/0x0bc529c00c6401aef6d220be8c6ea1667f6ad93e): 0.05 -* ALCX: [0xdbdb4d16eda451d0503b854cf79d55697f90c8df](https://etherscan.io/address/0xdbdb4d16eda451d0503b854cf79d55697f90c8df): 4 -* ALPHA: [0xa1faa113cbe53436df28ff0aee54275c13b40975](https://etherscan.io/address/0xa1faa113cbe53436df28ff0aee54275c13b40975): 1600 -* MKR: [0x9f8f72aa9304c8b593d555f12ef6589cc3a579a2](https://etherscan.io/address/0x9f8f72aa9304c8b593d555f12ef6589cc3a579a2): 0.5 -* REN: [0x408e41876cccdc0f92210600ef50372656052a38](https://etherscan.io/address/0x408e41876cccdc0f92210600ef50372656052a38): 2000 -* CRV: [0xd533a949740bb3306d119cc777fa900ba034cd52](https://etherscan.io/address/0xd533a949740bb3306d119cc777fa900ba034cd52): 360 -* RGT: [0xd291e7a03283640fdc51b121ac401383a46cc623](https://etherscan.io/address/0xd291e7a03283640fdc51b121ac401383a46cc623): 50 -* NFTX: [0x87d73e916d7057945c9bcd8cdd94e42a6f47f776](https://etherscan.io/address/0x87d73e916d7057945c9bcd8cdd94e42a6f47f776): 14 -* LON: [0x0000000000095413afc295d19edeb1ad7b71c952](https://etherscan.io/address/0x0000000000095413afc295d19edeb1ad7b71c952): 850 -* MASK: [0x69af81e73a73b40adf4f3d4223cd9b1ece623074](https://etherscan.io/address/0x69af81e73a73b40adf4f3d4223cd9b1ece623074): 140 -* BANK: [0x24a6a37576377f63f194caa5f518a60f45b42921](https://etherscan.io/address/0x24a6a37576377f63f194caa5f518a60f45b42921): 15 -* SFI: [0xb753428af26e81097e7fd17f40c88aaa3e04902c](https://etherscan.io/address/0xb753428af26e81097e7fd17f40c88aaa3e04902c): 3.3 -* VSP: [0x1b40183efb4dd766f11bda7a7c3ad8982e998421](https://etherscan.io/address/0x1b40183efb4dd766f11bda7a7c3ad8982e998421): 260 -* FRAX: [0x853d955acef822db058eb8505911ed77f175b99e](https://etherscan.io/address/0x853d955acef822db058eb8505911ed77f175b99e): 1500 -* DEXTF: [0x5f64ab1544d28732f0a24f4713c2c8ec0da089f0](https://etherscan.io/address/0x5f64ab1544d28732f0a24f4713c2c8ec0da089f0): 5000 -* ORN: [0x0258f474786ddfd37abce6df6bbb1dd5dfc4434a](https://etherscan.io/address/0x0258f474786ddfd37abce6df6bbb1dd5dfc4434a): 210 -* BOND: [0x0391d2021f89dc339f60fff84546ea23e337750f](https://etherscan.io/address/0x0391d2021f89dc339f60fff84546ea23e337750f): 55 -* LUSD: [0x5f98805a4e8be255a32880fdec7f6728c6568ba0](https://etherscan.io/address/0x5f98805a4e8be255a32880fdec7f6728c6568ba0): 1500 -* iFARM: [0x1571ed0bed4d987fe2b498ddbae7dfa19519f651](https://etherscan.io/address/0x1571ed0bed4d987fe2b498ddbae7dfa19519f651): 9 -* yvUSDC: [0x5f18c75abdae578b483e5f43f12a39cf75b973a9](https://etherscan.io/address/0x5f18c75abdae578b483e5f43f12a39cf75b973a9): 1400 -* UST: [0xa47c8bf37f92abed4a126bda807a7b7498661acd](https://etherscan.io/address/0xa47c8bf37f92abed4a126bda807a7b7498661acd): 1500 -* BNT: [0x1f573d6fb3f13d689ff844b4ce37794d79a7ff1c](https://etherscan.io/address/0x1f573d6fb3f13d689ff844b4ce37794d79a7ff1c): 380 -* vBNT: [0x48fb253446873234f2febbf9bdeaa72d9d387f94](https://etherscan.io/address/0x48fb253446873234f2febbf9bdeaa72d9d387f94): 1200 -* BAND: [0xba11d00c5f74255f56a5e366f4f77f5a186d7f55](https://etherscan.io/address/0xba11d00c5f74255f56a5e366f4f77f5a186d7f55): 200 -* SDT: [0x73968b9a57c6e53d41345fd57a6e6ae27d6cdb2f](https://etherscan.io/address/0x73968b9a57c6e53d41345fd57a6e6ae27d6cdb2f): 740 -* KP3R: [0x1ceb5cb57c4d4e2b2433641b95dd330a33185a44](https://etherscan.io/address/0x1ceb5cb57c4d4e2b2433641b95dd330a33185a44): 1.2 -* CREAM: [0x2ba592f78db6436527729929aaf6c908497cb200](https://etherscan.io/address/0x2ba592f78db6436527729929aaf6c908497cb200): 35 -* CHAIN: [0xc4c2614e694cf534d407ee49f8e44d125e4681c4](https://etherscan.io/address/0xc4c2614e694cf534d407ee49f8e44d125e4681c4): 9400 -* ERN: [0xbbc2ae13b23d715c30720f079fcd9b4a74093505](https://etherscan.io/address/0xbbc2ae13b23d715c30720f079fcd9b4a74093505): 110 -

This will involve adding it to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 0.1 WETH per request. - -## Motivation -ETH is the most liquid currency on Ethereum. Many users on Ethereum like to borrow against their ETH to get leverage on their ETH. At the time of writing, over 1.9mm ETH are locked in MakerDAO in this fashion. To allow synthetic tokens created with the EMP to take advantage of this liquidity and desire for leverage, WETH (ETH wrapped in an ERC20) seems like an important and safe addition to Dai as the second approved collateral currency. - -WETH as collateral is expected to have a variety of deployments. The timing for adding it now, and the immediate application, is for use with USDETH, which will enable the creation of yUSD, a yielding dollar token. This price identifier is described in UMIP 6. - -## Technical Specification -To accomplish this upgrade, two changes need to be made: -- The WETH address, [0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2](https://etherscan.io/token/0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2), needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 0.1 needs to be added for the WETH in the Store contract. - -## Rationale - -The rationale behind this change is giving deployers more useful collateral currency options. WETH needs to be used instead of ETH due to it being an ERC20, whereas native ETH is not. - -0.1 was chosen because 0.1 WETH is about twice as large as the current DAI final fee (10 DAI). This accounts for the fact that WETH is a much more volatile asset. Voters cannot change the final fees immediately when the price changes on collateral assets, so this additional cushioning helps protect the system from DoS attacks in times of volatility. - -## Implementation - -This change has no implementation other than the two aforementioned governor transactions that will be proposed. - -## Security considerations -Since WETH is a persistently valuable ERC20 token, including it as a collateral currency should impose no additional risk to the protocol. - -The only security implication is for contract deployers and users who are considering using EMP contracts with WETH as the collateral currency. They should recognize that, relative to most fiat currencies, WETH is much more volatile than Dai. This volatility should be taken into account when parameterizing or using these EMP contracts. - -For added assurance, WETH is not listed on the [buggy ERC20 contracts list](https://github.com/sec-bit/awesome-buggy-erc20-tokens/blob/master/bad_tokens.all.csv). diff --git a/research/uma/umips/umip-100.md b/research/uma/umips/umip-100.md deleted file mode 100644 index fff3227c..00000000 --- a/research/uma/umips/umip-100.md +++ /dev/null @@ -1,101 +0,0 @@ -# Headers - -| UMIP-100 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add `SelfMintingDerivativeFactory` as `Creator` in DVM registry | -| Authors | Pascal Tallarida (pascal@jarvis.network) | -| Status | Approved | -| Created | 12/05/2021 -| Discourse link | https://discourse.umaproject.org/t/add-selfmintingderivativefactory-as-creator-new-uma-fork/1079 | - -# Summary - -Last year, we have forked the perpetual contracts implementation of UMA and proposed the [UMIP-34](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-34.md) to integrate it within the DVM. We called this contract PerpetualPoolParty. This fork allows our synthetic assets to be multi-collateralized (multiple collateral linked to multiple Derivatives contract can back the same synthetic asset), perpetual (but without stability fee, funding rate etc.), and permissioned (only our whitelisted Smart Contracts can mint them). - -The UMA’s governance approved this fork earlier this year, allowing us to launch our mainnet. - -The PerpetualPoolParty was a “broker contract” allowing the end-users to trade against a smart contract (the broker's liquidity pool) which is the sole Token Sponsor: when a user wants to buy a synthetic asset, it triggers a mint transaction where the liquidity pool self-mints a synthetic fiat with a collateral in USDC deposited by liquidity providers, and sell this synthetic fiat for USDC to the end-user, at the Chainlink price, within the same transaction. - -Now we are about to launch our “bank contract” which allows anyone to be a Token Sponsor, pretty much like the EMP. Yet, we could not use the EMP due to some specification of our protocols (multi-collateral synthetic assets, perpetual, set minting limits, etc.). So we forked PerpetualPoolParty. - -More information regarding the broker and bank protocols can be found [here](http://bit.ly/Synthereum_Manifesto). - -The goal of this UMIP is to integrate `SelfMintingDerivativeFactory` in the DVM. - -Once `SelfMintingDerivativeFactory.sol` receives the `Creator` role it will register every `SelfMintingPerpetualMultiParty.sol` that is deployed through it with the UMA Registry so they can request prices from the DVM. - -# Motivation - -The "broker contract" was the first piece of our protocol to allow anyone to swap a synthetic assets for USDC at the oracle price (using Chainlink); this allows for the creation of a primary market, and help synthetic assets listed on secondary markets to maintain their peg through arbitrage. Although, the "broker contract" requires liquidity to function, which limits the issuance of synthetic assets. - -The "bank contract" will allow us to scale as it will allow anyone to self-mint perpetual synthetic assets by depositing a supported collateral, without funding fees or interests. The combination of the two contracts (bank and broker) provides a mechanism to maintain a peg: if the price is above the peg, one can mint a synthetic asset, sell it on a secondary market for USDC, and use part of these USDC to buy back the synthetic assets from the broker contract, to burn them and redeem their collateral. It also provides an instant liquidity to any synthetic assets minted though the "bank contract": one could use $UMA to self-mint jEUR, and instantly sell them for USDC at the oracle price. Today, self-minting a synthetic dollar using UMA occurs a slippage when selling it. - -The "bank contract" charges a fee, paid in the collateral deposited, when the user mints, deposits, repays and redeems. The fees are then transferred to the Jarvis protocol's treasury. - -Giving `Creator` role to `SelfMintingDerivativeFactory.sol` would allow more scalable and liquid synthetic assets to be backed by the UMA liquidation/dispute system, since every newly deployed derivative (`SelfMintingPerpetualMultiParty.sol`) is registered with the DVM. - -# Technical Specification - -### Here is a breakdown on the whole deployment process of a new derivative: - -1. Our DAO address (which is currently a team address until the DAO is set up) calls `deployOnlySelfMintingDerivative()` of `Deployer.sol`. -2. `Deployer.sol` calls `createPerpetual()` function of `SelfMintingDerivativeFactory.sol` and this function will use the `createPerpetual()` function of the contract `SelfMintingPerpetutalMultiPartyCreator.sol` that will call `SelfMintingPerpetualMultiPartyLib.sol` which will deploy a new `SelfMintingPerpetualMultiParty.sol` contract. -3. In the process of deployment `SelfMintingDerivativeFactory.sol` uses the internal function of `SelfMintingPerpetutalMultiPartyCreator.sol` called `_setControllerValues()` to set the CapMintLimit, CapDepositRatio and Fee for the new `SelfMintingPerpetualMultiParty.sol` in the `SelfMintingController.sol`. - - -### Modifications done: - -1. Transaction fees : we have added functions to calculate and to transfer fees that are being paid when a user mint, redeem and repay. Fees are paid with the collateral. Fee calculation = the number of tokens to mint, redeem or repay * GCR * fee (in %). - -2. Deposit collateral ratio (DCR) is capped : this is the ratio between the deposited collateral and number of tokens minted. It comes in addition to the GCR: the latter sets a collateral ratio limit below which it is not possible to mint; the DCR sets a limit above which it is not possible to mint; this is done in order to prevent someone to manipulate the GCR. Like the GCR, the DCR is used in the mint, deposit and repay function. - -3. Minting is capped : it limits the number of tokens that the derivatives can mint so we can scale according to the demand, liquidity and security. Caps will be increased as security audits are being completed, and as liquidity on our Broker contracts (PerpetualPoolParty) deepen. Also the `CapMintLimit` parameter allows us to avoid a situation in which arbitrage opportunities could potentially be blocked thus affecting the peg of our synthetic tokens across various DEXes. By setting the cap below the currently minted synthetic assets on our broker contract we ensure that an attacker can not self-mint a synthetic asset and redeem an amount equal to the total amount of assets minted from our broker contract, which would block users from redeeming USDC from the broker contract until new tokens are minted and this could lead to impossibility to perform arbitrage and keep the peg with secondary markets. -Under certain conditions, limiting the cap has a downside: if there is not enough synthetic asset on the secondary market to buy them to liquidate a position, it is possible that the limit prevents minting enough synthetic to do so. - -4. Make the contract permissionless : the PerpertualPoolParty contract was permissioned (only whitelisted pools can be a Sponsor). We changed this so anyone can become a Sponsor, like it is now in any UMA derivatives of course. - -5. Remove the liquidity pool logic : the current PerpetualPoolParty contract works with liquidity pools. - -6. The derivatives parameters (CapDepositLimit, CapMintLimit and Fee) are now stored in a controller contract (`SelfMintingController.sol`): this allows us to change those parameters while keeping the same derivatives. - -7. In the factory smart contract, we can only link the derivative contract to an existing synthetic asset, which have been previously deployed. - -8. Fees, deposit limit, mint limit are upgradable through the `SelfMintingController.sol` contract. - -No change for the liquidation. - -### Nesting of the contracts: - -1. `SelfMintingPerpetualMultiParty.sol` is a derived contract that inherit from `SelfMintingPerpetualLiquidatableMultiParty.sol`. -2. `SelfMintingPerpetualLiquidatableMultiParty.sol` is derived contract that inherit from `SelfMintingPerpetualPositionManagerMultiParty.sol`. -3. `SelfMintingPositionManagerMultiParty.sol` is derived contract that inherit from `FeePayerParty.sol` -4. `SelfMintingController.sol` contract is used to track and update the CapDepositLimit, CapMintLimit and Fee for the self-minting derivatives. - -Each one of those contract has its own library for gas optimization: -1. `SelfMintingPerpetutalMultiPartyCreator.sol` uses `SelfMintingPerpetualMultiPartyLib.sol` for gas optimization. -2. `SelfMintingPerpetualLiquidatableMultiParty.sol` uses `SelfMintingPerpetualLiquidatableMultiPartyLib.sol` for gas optimization. -3. `SelfMintingPerpetualPositionManagerMultiParty.sol` uses `SelfMintingPerpetualPositionManagerMultiPartyLib.sol` for gas optimization. - -# List of deployed contracts: - -1.

This possible threat is magnified by the high volatility of possible collateralTokens used for the self-minting derivatives. However by running liquidation bots the possible undercapitalization situation can be avoided.

However, Bob, being a wise investor, would probably not lock all of his tokens in the option contract (unless he does not believe the price is likely to be reached at all).

This UMIP does not attempt to put any other restrictions on the content of the query, and instead leaves construction of the query up to the requester within ancillary data. - -Price settlement can happen in four ways: -- Return the `p1` value from ancillary data if the answer is "NO". -- Return the `p2` value from ancillary data if the answer is "YES". -- Return the `p3` value from ancillary data if the answer cannot be determined. -- Return the `p4` value if the answer cannot be determined AND there is either an `earlyExpiration:1` key value pair present in ancillary data, or there is a specific last possible request timestamp listed or implied in the ancillary data question and the active price request timestamp falls before that. - -# Motivation - -Approving this price identifier will allow for a variety of products without the burden of having to vote in additional price identifiers.

If this is an "early expiration" price request, voters should first determine if the question in the ancillary data can be resolved definitively at this point in time.

Users of this price identifier should be careful to construct a question in a way that they can be sure that a deterministic outcome can be reached. - -There are also potential contract-level attacks that could result from people intentionally asking non-deterministic questions and using this to their advantage.

The type of price that the DVM will return is dependent on the timestamp the price request is made at. This timestamp is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the closing index value of uSTONKS calculation is used at expiry. This is very similar to the uGAS token and this design is outlined in [UMIP 22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md). - -Because the uSTONKS index value is only used at expiry, it will not be possible for a token sponsor to become undercollateralized based upon its movement. This means that only the Uniswap TWAP will need to be queried in real-time with a price feed. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. - -## TECHNICAL SPECIFICATIONS -- Price Identifier Name: uSTONKS_0921 -- Base Currency: uSTONKS_0921 -- Quote currency: None. This is an index, but will be used with USDC. -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE -The uSTONKS token is an expiring token that settles at the end of the expiry month using the final exchange closing prices on the last business day of the month for the ten stocks in the basket. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because uSTONKS is a decentralized synthetic that trades continuously 24/7 whereas the underlying stocks in the uSTONKS index trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. Using price feeds from the exchanges to monitor collateral ratios of token sponsors could be problematic outside of market hours especially if there is significant news released or general macro market forces. Though some stocks are traded after hours, the ability to extract this price data is difficult and the frequency may not be consistent across all ten stocks. Therefore, using the uSTONKS token price itself to monitor collateral ratios is a much better alternative as it should reflect the actual price movements during exchange hours and also reflect expectations of price movements after market hours. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -The stocks chosen represent the stocks with the highest average comment volume on r/WallStreetBets. This index was picked on June 14th, 2021 using r/WallStreetBets comment analysis from swaggystocks.com, and will remain static throughout the life of the price identifier. - -## IMPLEMENTATION -Voters should determine which pricing implementation to use depending on when the price request was submitted. - -**At Expiry** - -If the price request's UTC timestamp is at 1633046400 (Oct. 1, 2021 00:00:00 UTC), a price request for uSTONKS for a given timestamp should be determined by performing the `At Expiry` process. - -To create a baseline for the uSTONKS index, a base price for each stock was chosen. These prices are the closing prices of each on 06/15/2021 and can be used by voters as reference values for their calculations. Voters are highly encouraged to verify these values themselves. This basket is static - it will not change over the life of the contract. - -| Ticker | Stock Price 06/15/2021 | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| AMC | 59.04 | -| BB | 13.99 | -| GME | 222.50 | -| CLNE | 11.11 | -| CLF | 22.86 | -| UWMC | 9.81 | -| SENS | 3.69 | -| SPY | 424.48 | -| CLOV | 13.77 | -| WKHS | 14.15 | - -Each stock also is assigned an index value base. The index is equally weighted, so each stock is assigned a base of 10. This means that on 06/15/2021 at close, the uSTONKS index would have been worth 100 with every component making up 1/10th of that index. - -To calculate the uSTONKS price, an UMA voter should: -1. Query for the close price of one component on September 30, 2021. It is recommended that voters use the Google Sheets GOOGLEFINANCE function. -2. Divide the September 30 price by the base price and multiply by the index value base (10) to get today’s index value. -3. Perform this function for each component in the index and sum all of the results together. -4. Round the result of step three to six decimal places - -An example of this calculation is shown in [this](https://docs.google.com/spreadsheets/d/1IbvIZUGQG2TW9YLrV7ykPr3P2F4PhvgvOU-4o2RujZc/edit?usp=sharing) Google Sheet. - -It is possible that, over the life of this price identifier, certain situations could arise that would affect the validity of the index calculation. Guidance is provided below for certain situations, but voters are free to come to an alternative consensus if a flaw in the methodology is identified or an unforeseen event occurs. - -1. In the case of a stock split, the base price of the stock should be divided by the number of shares that the stock is being split into. As an example - if GME issued a 4:1 stock split, the base price of GME, 222.50, would be divided by 4 and the new base index price would be 55.63. -2. In the case of a stock consolidation, the process is the same as for a stock split, except the base price should be multiplied by the number of shares being consolidated. - -**Before Expiry** - -If the price request's UTC timestamp is less than 1633046400 (Oct 1, 2021 00:00:00 UTC), voters will need to calculate a 2-hour TWAP for the uSTONKS_0921 token’s price in USDC. The following process should be used to calculate the TWAP. -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Sushiswap price is defined for each timestamp as the price that the uSTONKS_0921 / USDC pool returns in the latest block where the block timestamp is <= the price request timestamp. This is the price of 1 uSTONKS_0921 token in USDC. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. This results should be rounded to 6 decimals. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -## Security Considerations -Security considerations are focused on the use of the token price for monitoring collateral ratios. -- Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -- Mismatch between TWAP and gap higher in token price - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uSTONKS_0921, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -Security considerations, like the ones above, have been contemplated and addressed, but there is potential for security holes to emerge due to the novelty of this price identifier. - -Additionally, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Contract deployers should also ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier or editing its implementation if security holes are identified. diff --git a/research/uma/umips/umip-11.md b/research/uma/umips/umip-11.md deleted file mode 100644 index 54a389c0..00000000 --- a/research/uma/umips/umip-11.md +++ /dev/null @@ -1,50 +0,0 @@ -# Headers - -| UMIP-11 | | -| ---------- | ----------------------------------- | -| UMIP Title | Add renBTC as a collateral currency | -| Authors | Adrian Li (adrian@umaproject.org) | -| Status | Approved | -| Created | August 26, 2020 | - -## Summary - -This UMIP will add renBTC as an approved collateral currency. This will involve adding it to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 0.018 renBTC per request. - -## Motivation - -BTC is the world’s largest and most popular cryptocurrency by market capitalization as well as traded volume. Many holders of BTC like to borrow against their BTC to get leverage on their BTC. At the time of writing, over 7,000 WBTC are locked in MakerDAO in this fashion. - -To allow synthetic tokens created with the EMP to take advantage of this liquidity and desire for leverage, an ERC20-compliant representation of BTC is required. renBTC is an ERC20 token backed 1:1 with BTC using the decentralized Ren Protocol. - -renBTC as collateral is expected to have a variety of deployments. The timing for adding it now, and the immediate application, is for use with USDBTC, which will enable the creation of yUSD, a yielding dollar token. This price identifier is described in [UMIP-7](./umip-7.md). - -## Technical Specification - -To accomplish this upgrade, three changes need to be made: - -- The renBTC address, 0xeb4c2781e4eba804ce9a9803c67d0893436bb27d, needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 0.018 needs to be added for renBTC in the Store contract. -- The precision for the USDBTC price identifier needs to be amended to 8 decimals instead of the usual 18 in order to comply with renBTC’s 8 decimals of precision. - -## Rationale - -The rationale behind this change is giving deployers more useful collateral currency options. renBTC needs to be used instead of BTC due to it being an ERC20 representing BTC on the Ethereum blockchain, whereas native BTC does not exist on the Ethereum blockchain. - -renBTC was chosen in particular due to the fact that renBTC is the most popular (and largest) truly decentralized BTC-representing coin on the Ethereum blockchain. It is not being chosen at the exclusion of other possible BTC-representing coins, but it is a natural first choice for this purpose. - -While wBTC currently has larger market dominance than renBTC, it is worth noting that renBTC has already gained significant traction in the DeFi space. There exists a large amount of renBTC liquidity on Curve Finance ($98m), Balancer ($5m), and Uniswap ($150k). - -Large projects like Compound and Maker already have wBTC as a collateral type, so using renBTC within the UMA ecosystem can serve to differentiate the UMA community in terms of promoting a more decentralized version of BTC on the Ethereum blockchain. - -## Implementation - -This change has no implementation other than adding the collateral type to the whitelist. - -## Security considerations - -renBTC is minted with real BTC via RenVM, a trustless and decentralized virtual machine run by a network of nodes known as Darknodes. A user first sends BTC to a dedicated Bitcoin address generated by a dapp and verified by RenVM. The BTC is held in custody by RenVM's decentralized network of Darknodes. renBTC is backed 1:1 with BTC. - -Since renBTC is minted trustlessly as a token backed via the Ren Protocol, including it as a collateral currency should impose minimal risk to the protocol. - -The only security implication is for contract deployers and users who are considering using EMP contracts with renBTCC as the collateral currency. They should recognize that, relative to most fiat currencies, renBTC is much more volatile than Dai. This volatility should be taken into account when parameterizing or using these EMP contracts. diff --git a/research/uma/umips/umip-110.md b/research/uma/umips/umip-110.md deleted file mode 100644 index 1c0715d9..00000000 --- a/research/uma/umips/umip-110.md +++ /dev/null @@ -1,546 +0,0 @@ -## Headers - -| UMIP-110| | -| ------------------------|------------------------------------------------------------------------------------------------------------------------ | -| UMIP Title | Add BASKUSD, USDBASK, APWUSD, USDAPW, SNOWUSD, USDSNOW as supported price identifiers | -| Authors | Shawn C.

DeFi users can deposit their interest bearing tokens of other protocols during defined future periods and trade in advance the future yield that their funds will generate.APWine tokenises the future yield leveraging two types of tokens in that process: -* Future Yield Tokens (FYT) (ERC20): They represent the future yield generated by an asset on one platform for a defined period. For example, one 30D-AAVE-ADAI-0 represents the yield generated by 1 ADAI (a.k.a. one DAI deposited on AAVE) during the first 30 days period. APWine features a dedicated exchange for users to sell and buy FYTs. - -* APWINE IBT (ERC20): The APWine interest bearing token. At any moment its holder can withdraw the corresponding depositing funds from the APWine protocol. APWINE IBT holders will receive an amount of FYT proportional of to the amount they hold (for the future the ibt corresponds to).

One example of a KPI metric is Integrations. Integrations serve to measure the activity of the protocol rather than assigning all of the value to the dollar amount generated by the protocol, as previously seen in UMA’s TVL KPI option. - -This UMIP enables the DVM to support price requests based on the number of qualifying integrations that occured during a specified timeline. This UMIP relies on the use of ancillary data, and will include a section on that below. - -A synthetic option is minted against a base collateral, in this case UMA. - - -# Motivation - -The primary motivation for the development of KPI options is to allow protocols and supporting organisations to incentivize DeFi users to assist them to reach identified targets by leveraging their community resources by sharing their value with their community members. - -Using integrations as a key metric directly benefits the UMA protocol because it encourages the community to build relationships in the broader DeFi community with the intention of providing tools that may be useful to teams who are currently unaware of what UMA has to offer. This creates a win-win across the board because it allows us to showcase our products and our products can then help other protocols to complete their goals. - -By establishing the terms of a qualifying integration, it allows for the community to reach out in a way that aligns with the current priorities of the UMA protocol- attracting attention to our strongest products and encouraging teams to test out a wide variety of use cases. - - -**It is anticipated that this Price Identifier will be used to create KPI Options, however it is acknowledged that it may be used for a variety of purposes.** - -# Data Specifications - -The UMA team will maintain a "green light" list of qualified integrations, which will be readily available upon request. This list will include details that voters need to assess the validity of the integration (e.g. launch and funding date of the contract so that voters can verify it is within the specified timeframe of the the current KPI option). Anyone can propose adding an integration to the list. Each integration will be added one at a time, after it has been discussed in the #voting channel in the UMA Discord. UMA tokenholders are encouraged to participate in these discussions in preparation for the formal proposed settlement. - -An integration will have been achieved when a DAO or other organisation funds an LSP contract which includes but is not limited to: - -* KPI options -* Call/Put options -* Range Bonds -* Success Tokens - -**Definitions:** -*Fund* - To fund means to take a DAO’s native token or another asset from the organisation's treasury and use it to collateralise an LSP contract The intention here is that these products will be used as a way to interact with the DAO's community or the organisation's supporters. There is an edge case here where a DAO or organisation might put money into a product with the intention to trade--This is not the spirit of this initiative and should not count towards an integration (although it is not discouraged behavior.) - -*Product Categories* - The four product categories have been explored and defined in a variety of articles, and many of the articles can be seen on UMA’s medium [page](https://medium.com/uma-project). These product types would primarily be built using UMA’s LSP (Long/Short Pair) contract, and in some cases can use the EMP contract. However, it is important to note that they will all be fully capitalized products, without any chance or need for liquidations. While multiple integrations per DAO/organisation can qualify, these should be substantively different products, rather than a repeat of the same product with variable parameters (such as expiry date). Should there be a dispute over whether an integration is "substantively different", a discussion is encouraged in the #voting channel on discord to inform UMA token holders of the arguments for and against so that they can make an informed decision about how many qualifying integrations have occurred at the time of the options expiry. - -*DAO* - A decentralized, autonomous organization. We would expect them to have a native token (although this is not a requirement) and a governance system. - -*Organisation* - An established entity which pre-dates the funding of the contract. - -**Ambiguity Considerations** - -It may be unclear whether new projects with illiquid tokens meet the criteria of a "DAO" or an "Organisation". We wouldn’t want to exclude this valuable integration type from inclusion in the KPI Options. This is a category that we will leave to UMA tokenholders to evaluate. As a guiding principle, a qualifying DAO is part of a good faith project; a disqualifying DAO would be one with no genuine attempt at a company or organization. Any ambiguities around the question of, "is it a DAO?" will be discussed in the #voting channel on the UMA Discord. It is especially important to the design of this UMIP that UMA tokenholders participate in these discussions to establish borad consensus on questions that don't have black and white answers. - -**Bonus Integrations** - -As seen below in the ancillary data section, this UMIP allows for the deployer of the contract to include bonus parameters for integrations above a set TVL threshold, denominated in $USD. If a deployer elects to include a bonus option, they should specify the minimum value required to qualify, the max number of integrations that can qualify for a bonus, and the multiplier to be applied to these integrations. To be consistent throught this UMIP, an integration will qualify for a bonus if it reaches the TVL threshold at any point in the life of the kpi option. If an integration qualifies for the specified bonus, it will be indicated on the "green light" list with a 🐋. - -It is assumed that the collateral token in most cases will not be USD. If there is a dispute over whether the collateral's value in USD, is in excess of level required for it to qualify for as a "Bonus Integration this should be discussed in the #voting channel in UMA Discord. - -**Additional Notes:** - -LSP contracts deployed by UMA for use by UMA do not count, but if UMA deploys a contract for use by another team, it is eligible as long as it meets the criteria above. - -Contracts included are not limited to Ethereum mainnet. Contracts on other chains where DVM message bridging is available (e.g. Polygon) will be included in consideration. - -The applied timeframe for this UMIP will be specified in ancillary data, and all qualifying integrations launched and funded during this timeframe should be counted. - -The "green light" list should not be considered the *only* source of truth, but rather a reflection of the discussions that take place within the community. The DVM has the ability and responsibility to challenge the validity of any integrations that have been included or excluded from the list if the broader consensus of UMA tokenholders is that it is within the spirit of this UMIP to do so. Any and all questions surrounding the validity of an integration can be brought up in further detail in the #voting channel on the UMA Discord. - -# Ancillary Data Specifications -The following pieces of data will be included as ancillary data when the contract is deployed, and will provide additional details & instructions to help voters correctly identify the number of qualifying integrations. - -* `startTimestamp` (unix timestamp) -* `maxBaseIntegrations` (non-negative integer) -* `maxBonusIntegrations` (non-negative integer) -* `bonusMinValue` (TVL threshold for bonus integrations represented in $USD) -* `bonusIntegrationsMultiplier` (non-negative number rounded to 2 decimals) -* `floorIntegrations` (non-negative integer) - -Ancillary data should be passed into the contract using the format in the example below. -``` -startTimestamp:1622527200, maxBaseIntegrations:15, maxBonusIntegrations:3, bonusMinValue:$1,000,000, bonusIntegrationsMultiplier:3.00, floorIntegrations:3 -``` - -If a contract deployer incorrectly formats or simply does not provide one of the parameters above, it will default to the following values. This means that if no ancillary data is present, the value returned should be 0. - -* `startTimestamp` (timestamp of contract deployment) -* `maxBaseIntegrations` (0) -* `maxBonusIntegrations` (0) -* `bonusMinValue` ($0) -* `bonusIntegrationsMultiplier` (0.00) -* `floorIntegrations` (0) - -# Technical Specifications - -- **Price identifier name:** *uDAO_KPI_UMA* -- **Base: Number of qualified DAO integrations -- **There is no quote currency in this option, as design feature. The collateral redemption is tied to the** *number of qualified integrations* **by design** - - **Intended Collateral Currency** *UMA*. -- **Rounding:** *Round to 2 decimals* - - -# Rationale - -* Linear scaling is used for sake of ease for contract deployment and for voters. Integrations that qualify for a bonus will simply be treated as multiple integrations as a way to recognize the increased value and work needed to get them across the finish line. - -* Allowing for a specified minimum payout is intented to account for the integrations that occurred prior to launch, in an effort to reward the community for hard work leading up to the launch of this KPI option. - -* Minimum payout may be established in ancillary data via the `floorIntegrations` parameter, or it can be baked into the contract. This is a design decision to be made by the contract deployer. If it is baked into the contract, details can be customized using the [financial-products-library](https://github.com/UMAprotocol/protocol/tree/master/packages/core/contracts/financial-templates/common/financial-product-libraries/long-short-pair-libraries). Allowing variations of this feature as a design choice allows deployers to weigh the pros and cons of exchainging simplisity for transparancy. In both cases, more details on minimum payout and scaling can be found within the deployed contract. - -* The decision to limit qualifying integrations to the LSP contract and highlight the listed product types was made in order to focus the community and align incentives with the strategic goals of the organization. - -* Setting it up to allow for all qualified launches to be counted throughout the period rather than just at the time of expiry helps to ensure that we are not missing out on any integrations that might expire before the KPI option does. The same logic is applied to bonus qualifying integrations. - -* Having a customized starting timestamp allows a contract deployer to include integrations that occur prior to launch of this option. This design feature can act to reward the community for prior work done and may also help keep momentum going while the current KPI expires. - -* The rationale for choosing integrations was to emphasize building DAO-to-DAO relationships and wider relationships between UMA and the wider Defi community. UMA’s product suite has increasingly gained focus and traction on DAO treasury management. However, it is not scalable for the development team to focus on promotion and integration efforts alone, and this KPI Option has been designed to help recruit the community to help. - - -# Implementation - -Step 1: Refer to "green light" list for finalized information on all qualified integrations. Assign 1 point for each integration on the list, including any integrations that have qualified for a bonus. - -Step 2: If an integration qualifies for a bonus, it will be indicated with a 🐋. These integrations are worth some multiplier of points *in addition* to the base points counted above. This multiplier will be specified in the ancillary data as `bonusIntegrationsMultiplier`. Keep track of bonus points and base points separately. - -* Note for step 2: In order for an integration to earn a 🐋 marker, it must meet the minimum TVL threshold as defined in the ancilary data parameter `minBonusValue`. This value is denominated in $USD rather than the collateral token, so discussion of $USD value had to take place in the #voting channel in UMA Discord in order for an integration to earn this status. For additional details on bonuses, see the above section on bonus integrations. - -Step 3: Tally up the total number of base points as well as the number of bonus points. At this point, the two numbers should be separate. - -Step 4: Using the ancillary data specifications for `maxBaseIntegrations` and `maxBonusIntegrations`, decide if your tally exceeds the max allowed for either category. If the value of your tally exceeds the max allowable points in either category, use the value provided by `maxBaseIntegrations` and `maxBonusIntegrations`. - -Step 5: Add base points plus bonus points from the step above for the total number of points. This is the value you will return. If the value returned would be lower than `floorIntegrations`, use the value provided by this field in ancillary data. - - -# Security Considerations - -Due to the bespoke nature of this UMIP, it should not be considered a standard against which future UMIPs can be measured without considering the amount of risk in establishing a set of rules as qualitative as is the case here. When assessing the risk of using qualitative data to determine an outcome, several things have been considered, such as the intended "in house" use of this UMIP, the intended recipients of the uDAO token, the intended outcome of the KPI option, and how to handle any ambiguities that could arise over the course of this option. - -How could metric manipulation occur? - -* By establishing a discussion system for determining qualitative validity of an integration, it reduces the ability of any individual to game the system. The DVM voters have the ability to determine if it appears that someone is acting maliciously and can disqualify any integrations that majority believe should not be included. - -How could this price ID be exploited? - -* The definition of the metric is inherently qualitative, and utilizes a logic that requires an integration to "earn" its way onto a curated list. This factor, which relies on human judgement, makes it inprobable that it will be exploited. - -Do the instructions for determining the price provide people with enough certainty? - -* Yes. Voters need only return the number of qualified integrations at the time of expiry. - -Are there any current or future possible concerns with the way the price identifier is defined? - -* It could be determined that the scaling is not appropriate in the event of overwhelming failure of the option. This would happen if we achieved too few integrations or if we reach the goal too quickly. -* Additionally, there is the potential for ambiguities to present that have not been considered at the time of writing. In this case it will be up to the DVM to determine the resolution of those ambiguities. -* It is possible that over the course of the KPI option, UMA could determine there are other products they would like to prioritize that are not defined in this UMIP. In that case, another KPI option can be launched to include that product. - -Are there any concerns around if the price identifier implementation is deterministic? - -* The potential for ambiguities over definitions has been addressed above and a method of resolving them recommened to UMA Tokenholders. diff --git a/research/uma/umips/umip-113.md b/research/uma/umips/umip-113.md deleted file mode 100644 index d19e54a5..00000000 --- a/research/uma/umips/umip-113.md +++ /dev/null @@ -1,53 +0,0 @@ -## Headers -| UMIP-113 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Register Polygon Oracle Root Tunnel | -| Authors | Nick Pai (nick@umaproject.org) | -| Status | Approved | -| Created | July 8, 2021 | - -## Summary (2-5 sentences) -This UMIP will have the effect of registering an oracle root tunnel contract that will enable the optimistic oracle deployed on Polygon to make cross-chain price requests to the DVM on mainnet Ethereum. - -## Motivation -[This document](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/polygon/README.md) describes a two way tunnel architecture that is built on top of the [canonical state transfer mechanism](https://docs.polygon.technology/docs/develop/l1-l2-communication/state-transfer) between Polygon and Ethereum.

For example, [this price request](https://etherscan.io/tx/0x9d7a592c2d5dcd72b638967efff008f208bc1e5b06a0fa02b50114accf459370#eventlog) for the `SPACEXLAUNCH` identifier specifies `"id0:Transporter-2,w0:1"` in hex format as the ancillary data to inform voters about which rocket launch (e.g. the rocket is "Transporter 2" in this case) they should be voting on. - -Because ancillary data is a `bytes` data type, voter experience is enhanced if there is a soft standard for formatting the ancillary data. This is what the Risk Labs team has tried to do with [this document describing an ancillary data interface](https://docs.google.com/document/d/1zhKKjgY1BupBGPPrY_WOJvui0B6DMcd-xDR8-9-SPDw/edit?usp=sharing). In summary, the goal of this document is to encourage price requesters who use ancillary data to ensure that it can be decoded directly from `bytes` to `utf8` via standard client libraries such as `web3.js` and `ethers.js`, and that the `utf8`-encoded ancillary data is a comma-delimitted key-value dictionary just like the `SPACEXLAUNCH` example above. - -The current supported optimistic oracle "stamps" data to the ancillary data informing voters that any price requests were sent by an optimistic oracle. This is useful information and gives voters more information, but the "stamping" does not conform with the above interface; it produces `bytes` data that cannot be directly decoded to `utf8` format. - -This UMIP proposes to register an updated optimistic oracle that "stamps" ancillary data according to the above standard. - -## Technical Specification -To accomplish this upgrade, the following actions need to be taken: -- A new `OptimisticOracle` contract has been deployed. Address can be found in "Implementation" section. -- A transaction will need to be proposed to add this new address to the `Finder` contract under the name `“OptimisticOracle”`. This is how other contracts will find the optimistic oracle and reference it. -- The `OptimisticOracle` will need to be registered with the `Registry` so that it can make requests to the DVM. - -## Rationale - -This UMIP enhances voter experience by upgrading the optimistic oracle so that it will stamp ancillary data in such a way that any disputes that arise from it will include ancillary data that is easily translateable by UMA voters. - -## Implementation - -The `OptimisticOracle` contract implementation can be found [here](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/oracle/implementation/OptimisticOracle.sol).

The below listed key parameters will be used to instruct voters how to resolve a given price request for this identifier and request timestamp: - -- `Metric`: Short description reflecting the metric and units to be measured. -- `Endpoint` (optional): Link to data endpoint that should return the `Metric` at request timestamp. The response format should comply with the linked document from the `Method` parameter. The data endpoint should either allow passing the timestamp as parameter or returned data should include timestamp value for each returned data point. -- `Method`: Link to a descriptive source covering the objective and methodology for calculating a particular metric. This methodology should include how the calculation of the metric is measured. Links to repositories and explainer documentation are strongly recommended. Clearly articulate any post-processing required. -- `Fallback` (optional): In the event of the end-point not working or reporting false outcomes, a fallback ensures that UMA token holders can arrive at the proper result. If the methodology source demonstrates a fallback alternative, this field can be optional. -- `Key` (optional): Which key value from the `Endpoint` response should be used by voters for further processing of the price request. -- `Interval` (optional): This describes how request timestamps for pricing queries should be rounded and what is the granularity of historical data update frequency. -- `Aggregation` (optional): In case any time series data processing is required this describes processing method used (e.g. calculating TWAP, finding peak value, etc.) and also sets the start timestamp for such aggregation. -- `RawRounding` (optional): This is integer number defining how many digits should be left to the right of decimal delimiter after rounding the raw metric. -- `Scaling` (optional): This is integer number defining power of 10 scaling to be applied after rounding the raw metric. This is not to be confused with additional scaling performed by voting dApp, and it is just an optional transformation for scaling reported metric from the `Endpoint` instead (e.g. transforming USD to billions of USD). -- `Rounding` (optional): This is integer number defining how many digits should be left to the right of decimal delimiter after rounding the post-processed metric. -- `Unresolved` (optional): This is numeric value that voters should return for unresolvable price request (defaults to zero if omitted). - -KPI options launcher can also add any arbitrary ancillary data fields as long as they are clearly documented in the linked `Method` document and voters are instructed on how to interpret them for price processing. - -When designing the ancillary data KPI options deployer should be aware that the total size of ancillary data cannot exceed 8192 bytes also accounting for any ancillary data stamping by Optimistic Oracle.

In reality it should be more focused document developed by KPI launch team without going through UMIP approval process.* - -# Rationale - -The technical implementation of this price feed is to allow flexibility for project teams to self-report their own KPI metric. Scalability at the cost of clarity and security trade-off occurs when off-loading the reporting requires externally. - -The user of this UMIP accepts responsibility to provide the information passed through via ancillary data is sufficient to resolve price requests. Suppose the user of the price identifier cannot give enough information for UMA token holders to determine the outcome. In that case, UMA token holders can resolve the price request to zero (unless other non-zero unresolvable state value was provided in the ancillary data). The payout to long KPI option token recipients in unresolvable state would depend on actual financial product library (FPL) used, but for the most common [Linear LSP](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/financial-templates/common/financial-product-libraries/long-short-pair-libraries/LinearLongShortPairFinancialProductLibrary.sol) or [Binary LSP](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/financial-templates/common/financial-product-libraries/long-short-pair-libraries/BinaryOptionLongShortPairFinancialProductLibrary.sol) FPLs that would expire the long KPI option tokens in a worthless state. - -This UMIP also allows the use of KPI measures that may, in some part, rely on information that a trusted party may report. The assumption is that the party reporting the numbers is either trusted or has a vested interest in ensuring the accuracy of the price, but this is not guaranteed. As such, the voter follows i) the methodology outlined in the ancillary data, ii) the fall back alternative outlined in the ancillary data, iii) the most commonly agreed metric to measure a KPI (If and only if this measure is trusted). If none of these outcomes are achieved or the data source is corrupted then the price can be resolved to predefined value (defaulting to zero). - -# Implementation - -1. By default the value of this price identifier is determined by performing a GET request at the `Endpoint` parameter from the ancillary data of price request. Unless the data returned by the `Endpoint` already includes the `Metric` values across all required timestamps the voters should also pass the timestamp parameter to their GET request in the format following the instructions in the linked `Method` document. - - When passing on the timestamp parameter or observing the returned time series data the voters should consider the price request timestamp and any required timestamp rounding as described in the `Interval` parameter from the ancillary data. The voters should take note of the returned `Key` value as tracked raw metric. - - Though the `Method` document might provide alternative request methods (e.g. POST request with data), an alternative data source or predefined timing intervals that should be respected by the verifiers. If `Endpoint`, `Key` or `Interval` parameters are not provided the `Method` document should include precise instructions on how to identify the tracked metric at requested time from returned data. -2. In case the optional `Aggregation` parameter is set in the ancillary data voters should also collect values of tracked raw metric across all timestamps at intervals set in the `Interval` parameter (or interval instructions from the `Method` document) from the start timestamp (as provided in the `Aggregation` parameter) till the price request timestamp and perform any time series processing function described in the `Aggregation` parameter from the ancillary data. As a convenience, KPI options deployer might also provide the expected aggregated value in the `Endpoint` response, but voters are strongly advised to verify this value independently by performing time series processing defined in the `Aggregation` parameter. -3. If any additional ancillary data fields are documented in the linked `Method` document, voters should follow all instructions in this document based on actual additional ancillary data fields passed in the price request. -4. If `RawRounding` parameter from the ancillary data is provided and it is non-negative then round the obtained raw metric (or the result of its aggregation) leaving `RawRounding` number of digits after the decimal delimiter. In case the `RawRounding` parameter is negative then round to the nearest 10 to the power of absolute `RawRounding` value. For example, if `RawRounding` is -6 then one should round the value to the nearest million (10^6). -5. If `Scaling` parameter is passed in the ancillary data then multiply the rounded value of raw metric with 10 to the power of `Scaling`. For example, `Scaling` value of 6 would multiply by 1 million while -3 would effectively divide by 1 thousand. -6. It is recommended to perform any additional post processing in the financial product library so that voters can focus on resolving the raw value of `Metric` in question. In case when the available financial product libraries are missing the required functionality and it is impractical to develop new library KPI options deployer might include additional post processing instructions that voters must perform in the linked `Method` document from the ancillary data. -7. If `Rounding` parameter from the ancillary data is provided then round the processed metric (or raw metric if no post-processing was required) similarly as documented for `RawRounding` in Step 4. In case the `Rounding` parameter is not provided the verifiers should assume its default value of `0`. - -Voters should ensure that their results do not differ from broad market consensus. In particular, voters should verify whether the `Endpoint` source code referenced in the linked `Method` document is consistent with the objective and methodology for calculating particular metric, as well as attempt to run the data service independently and check the accuracy of data provided by the `Endpoint` service. In the event of the `Endpoint` not working or reporting false outcomes voters should follow any fallback instructions found in the linked `Method` document or the optional `Fallback` parameter in the ancillary data. - -Voters should also carefully follow any versioning history to the linked `Method` document and the `Endpoint` service source code. While it is possible that methodology and code could be improved over time in order to clarify any original oversight or fix bugs, voters should ensure that any changes are consistent with the original KPI options program launch objectives. - -In case the ancillary data provided does not comply with the ancillary data specification in this price identifier (to the extent that voters are unable to reasonably figure out what are the intended values of the required parameters) or the linked `Method` document is ambiguous or incomplete with unclear or missing fallback method, the voters should resolve the price request as zero. Though, the optionally passed `Unresolved` parameter in the ancillary data might set any other non-zero fallback value that the voters should return in case of any unresolvable ambiguity and voters should respect this fallback value to the extent it is unambiguously recognizable in the passed ancillary data. - -All resolved price values should be scaled by `1e18` when interacting with contracts directly (e.g. writing scripts, console access or interacting through block explorer). Optimistic Oracle and Voting dApps scales price response automatically so human readable prices should be provided by the users. - -# Security considerations - -This UMIP makes it easier for teams to launch their KPI options without having a pre-approved methodology. This opens the DVM to a potential situation where a price resolution may not be reached since the data is ambiguous or cannot be verified. This concern is addressed by allowing price resolutions for this price identifier to return a predefined value (defaulting to zero). - -An additional security concern is that of manipulation by the controlling entity of the data. Since the creator of a KPI can also be the entity reporting the results, there can be a trusted intermediary involved. To ensure the integrity of the reported figures, each price request will require a link to the methodology of how the feed is being calculated. It should be noted that a price request may be sent without a viable method attached and will be up to the voters to discern the accuracy of the reported figures. - - diff --git a/research/uma/umips/umip-118.md b/research/uma/umips/umip-118.md deleted file mode 100644 index 5f1ed4fc..00000000 --- a/research/uma/umips/umip-118.md +++ /dev/null @@ -1,832 +0,0 @@ -## Headers - -| UMIP-118 | | -| ------------------- | ------------------------------------------------------------- | -| UMIP Title | Add POOLUSD, USDPOOL, BADGER/USD, USD/BADGER, GNOUSD, USDGNO, OHMUSD, USDOHM, IDLEUSD, USDIDLE, FEIUSD, USDFEI, TRIBEUSD, USDTRIBE, FOXUSD and USDFOX as supported price identifiers | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | July 13, 2021 | -| Discourse Link | [UMA's Discourse](https://discourse.umaproject.org/t/price-identifier-omnibus-for-pool-badger-gno-ohm-and-idle/1248) | - -# Summary - -The DVM should support price requests for the below listed asset pairs: -- POOL/USD -- USD/POOL -- BADGER/USD -- USD/BADGER -- GNO/USD -- USD/GNO -- OHM/USD -- USD/OHM -- IDLE/USD -- USD/IDLE -- FEI/USD -- USD/FEI -- TRIBE/USD -- USD/TRIBE -- FOX/USD -- USD/FOX - -The canonical identifiers should be `POOLUSD`, `USDPOOL`, `BADGER/USD`, `USD/BADGER`, `GNOUSD`, `USDGNO`, `OHMUSD`, `USDOHM`, `IDLEUSD`, `USDIDLE`, `FEIUSD`, `USDFEI`, `TRIBEUSD`, `USDTRIBE`, `FOXUSD` and `USDFOX`. - -# Motivation - -These price identifiers would allow the above listed assets to be used for the creation range or success tokens. These tokens are also being proposed to be used as collateral in UMA contracts. As showcased in [this article](https://medium.com/uma-project/uma-raises-2-6mm-in-the-pilot-of-the-range-token-de5be578fa5e), the range token is a new treasury primitive that enables DAOs to access funds and diversify their treasury without directly selling their native tokens. - -Proactively approving these price identifiers will make it easier for development teams and protocol treasuries to create new products using these ERC20 tokens and their price identifiers. - -# Ancillary Data Specifications - -All of the proposed price identifiers can optionally include ancillary data to specify the twap length that these values should be computed using, as well as an optional ohlcPeriod parameter to specify an alternative price interval in seconds. As an example, a price request could specify daily TWAP over 30 days by passing following ancillary data: - -``` -twapLength:2592000,ohlcPeriod:86400 -``` - -When above ancillary data is stored as bytes, the result would be: - -`0x747761704c656e6774683a323539323030302c6f686c63506572696f643a3836343030` - -twapLength and ohlcPeriod should be specified in seconds. If a twapLength key value pair is not present, then voters should first default to the TWAP length(s) specified in `Implementation` or, if there is none, simply calculate the spot price and not a TWAP. If an ohlcPeriod key value pair is not present, voters should default to using 60 second ohlc intervals. - -# POOL - -## Data Specifications - ------------------------------------------ -- Price identifier name: POOLUSD and USDPOOL -- Markets & Pairs: - - POOL/ETH: [Uniswap v2](https://v2.info.uniswap.org/pair/0x85cb0bab616fe88a89a35080516a8928f38b518b) and [SushiSwap](https://analytics.sushi.com/pairs/0x577959c519c24ee6add28ad96d3531bc6878ba34) - - ETH/USD(T): Refer to `ETHUSD` in [UMIP-6](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-6.md) -- Example data providers: Refer to `ETHUSD` in [UMIP-6](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-6.md) -- Cost to use: Refer to `ETHUSD` in [UMIP-6](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-6.md) -- Real-time data update frequency: price is updated with every Ethereum block (~15 seconds per block) -- Historical data update frequency: price is updated with every Ethereum block (~15 seconds per block) - -## Price Feed Implementation - -This price identifier uses the [CryptoWatchPriceFeed](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/CryptoWatchPriceFeed.js), [UniswapPriceFeed](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) and [ExpressionPriceFeed](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/ExpressionPriceFeed.js) with example configuration below: - -``` - POOLUSD: { - type: "expression", - expression: ` - median( (POOL_ETH_UNI * ETHUSD), (POOL_ETH_SUSHI * ETHUSD) ) - `, - lookback: 7200, - minTimeBetweenUpdates: 60, - twapLength: 300, - ohlcPeriod: 60, - customFeeds: { - POOL_ETH_UNI: { - type: "uniswap", - uniswapAddress: "0x85cb0bab616fe88a89a35080516a8928f38b518b", - }, - POOL_ETH_SUSHI: { - type: "uniswap", - uniswapAddress: "0x577959c519c24ee6add28ad96d3531bc6878ba34", - }, - ETHUSD: { - type: "medianizer", - invertPrice: false, - minTimeBetweenUpdates: 60, - medianizedFeeds: [ - { type: "cryptowatch", exchange: "coinbase-pro", pair: "ethusd" }, - { type: "cryptowatch", exchange: "binance", pair: "ethusdt" }, - { type: "cryptowatch", exchange: "kraken", pair: "ethusd" }, - ], - } - }, - }, - USDPOOL: { - type: "expression", - expression: "1 / POOLUSD", - }, -``` - -## Technical Specifications - ------------------------------------------ -- Price identifier name: POOLUSD -- Base Currency: POOL -- Quote Currency: USD -- Rounding: Round to 8 decimal places (ninth decimal place digit >= 5 rounds up and < 5 rounds down) -- Estimated current value of price identifier: 9.18390777 (19 Jul 2021 12:00:00 GMT) ------------------------------------------ -- Price identifier name: USDPOOL -- Base Currency: USD -- Quote Currency: POOL -- Rounding: Round to 8 decimal places (ninth decimal place digit >= 5 rounds up and < 5 rounds down) -- Estimated current value of price identifier: 0.10888611 (19 Jul 2021 12:00:00 GMT) - -## Rationale - -POOL token does not have any recognizable liquidity on CEXs, thus, the only viable alternative currently is to query its pricing from available AMM pools on Uniswap and SushiSwap.

- -# Rationale - -**Why this implementation of the identifier as opposed to other implementation designs?** - -This implementation is due to ibBTC's main sources of liquidity being on Sushiswap. Currently, there are no centralized exchanges with ibBTC listed, and most liquidity will remain on DEXs as it is incentivized. - -**What analysis can you provide on where to get the most robust prices? (Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges)** - -Sushiswap on Ethereum and Polygon networks has the vast majority of ibBTC volume and depth. These should be used over all other sources. - -**What is the potential for the price to be manipulated on the chosen exchanges?** - -The potential risk for this is low. Ethereum and Polygon are reliable networks, and TWAP is used to hedge short term price manipulation. - -**Should the prices have any processing (e.g., TWAP)?** - -A 30 minute TWAP was chosen to help smooth out price changes and give sponsors time to react before becoming undercollateralized. A 30 minute TWAP will also mitigate risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. - -
- -# Implementation - -For all implementations, a block number will need to be used. The block number should be the block that is closest to and before the timestamp that the price request timestamp. - -For ibBTC/BTC and ibBTC/USD TWAP implementations, the TWAP start time should be determined by the latest block 30 minutes before requested timestamp. - -**For ibBTC/BTC and BTC/ibBTC** - - 1. Query ibBTC/WBTC Price from Sushiswap (Ethereum) using 30 minute TWAP (0x18d98D452072Ac2EB7b74ce3DB723374360539f1). - 2.

This result should have 8 decimals, rounding the closest 0.5 up. - 4. (for BTC/ibBTC) Take the inverse of the before-rounding result of step 3 to retain precision. - 5. (for BTC/ibBTC) Round result from step 4 to 8 decimals to get the BTC/ibBTC price. - -**For ibBTC/USD and USD/ibBTC** - - 1.

- -# Security Considerations - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradeable token price because the TWAP calculation is measured based on the price at the end of each block.

If a value should contain `,` or `:` characters, such value should be enclosed in double quotes. The below listed key parameters will be used to instruct voters how to resolve a given price request for this identifier and request timestamp: -- `base`: Collateral token symbol that should be priced in the submitted price request. -- `baseAddress`: `base` token deployment address on Ethereum network (or any other network if `baseChain` parameter is provided). In case the token is deployed on several networks the user of this price identifier is free to select any network as long as it allows correctly identifying the required base token. -- `baseChain` (optional): ChainID number for the network where base token is deployed. If omitted, Ethereum mainnet would be assumed. -- `quote`: Quote currency symbol in which the `base` token should be priced in -- `quoteDetails`: Additional details to unambiguously identify the quote currency. For cryptocurrencies or fiat currencies this should be the full name of the currency. For fungible tokens it should be the token address on Ethereum network or any other network if accompanied by its ChainID in this parameter. -- `rounding`: This is an integer number defining how many digits should remain to the right of the decimal delimiter after rounding the obtained price. -- `access` (optional): In case data sources in the `configuration` parameter require any special access tokens, this parameter should describe the source for acquiring access and any associated costs, as well as provide the key variable name for the `PRICEFEED_CONFIG` environment variable. -- `fallback`: Data endpoint(s) to use as a fallback mechanism either for the whole `base`/`quote` price request or resolving part of failing data source components (e.g. alternative for Token/ETH when calculating Token/USD). When providing alternative data source components it should be clearly indicated for which part of calculation this fallback source should be used. -- `unresolved` (optional): This is numeric value that voters should return for unresolvable price request (defaults to zero if omitted). -- `configuration`: Price feed configuration formatted as a JSON object that can be used to construct a price feed by [CreatePriceFeed.ts](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/CreatePriceFeed.ts). Please consult UMA documentation covering the selection and configuration of price feed for more details. Also note that default UMA price feed configuration is formatted as JavaScript objects, thus all key names should be enclosed in doublequotes, no comments are allowed, math expressions should be kept in one line and there should be no trailing commas after the last element in JSON. Even though technically proposer/dispute bots would be able to pick up any correctly formatted configuration for available price feed implementation, this price feed configuration should only be used for pricing the `base` token in terms of the `quote` currency. - -When designing the ancillary data TOKEN_PRICE user should be aware that the total size of ancillary data cannot exceed 8192 bytes also accounting for any ancillary data stamping by Optimistic Oracle.

Voters should decode the ancillary data and add the JSON object from the `configuration` parameter as a value (naming its key to be unique) to `defaultConfigs` dictionary object in [DefaultPriceFeedConfigs.ts](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/DefaultPriceFeedConfigs.ts). As an example, choosing `UMAUSD_CUSTOM` as key name from the example in Ancillary Data Specifications section would become: - ``` - const defaultConfigs = { - // Leave other price feed configs here - "UMAUSD_CUSTOM": { - "type": "medianizer", - "minTimeBetweenUpdates": 60, - "twapLength": 3600, - "medianizedFeeds": [ - { "type": "cryptowatch", "exchange": "coinbase-pro", "pair": "umausd" }, - { "type": "cryptowatch", "exchange": "binance", "pair": "umausdt" }, - { "type": "cryptowatch", "exchange": "okex", "pair": "umausdt" } - ] - } - } - ``` -2. In case there are syntax issues with the passed price feed `configuration` voters should attempt to fix it as long as it is unambiguously possible to infer the intended price sources and the calculation logic from this parameter. -3. Prepare the `.env` file in the root of UMA [protocol](https://github.com/UMAprotocol/protocol) repository - it should contain `CUSTOM_NODE_URL` variable pointing to Ethereum node (full archive node is required in case the price feed configuration depends on fetching historical state) and `PRICE_FEED_CONFIG={"lookback":300000}`. `lookback` value of 300000 seconds ensures that prices can be looked up historically during the maximum DVM resolvement period of 72 hours plus added reserve for any required TWAP start period before that. In case `access` parameter is passed on in the ancillary data, voters should also follow the instructions mentioned in this parameter and add any required API key to the `PRICE_FEED_CONFIG` dictionary object. -4. Voters should run the price feed with the selected key name as `--identifier` and requested timestamp as `--time` parameter from the root of UMA [protocol](https://github.com/UMAprotocol/protocol) repository. Following on the example above, the command would be: - ``` - HARDHAT_NETWORK=mainnet node ./packages/scripts/local/getHistoricalPrice.js --network mainnet_mnemonic --identifier UMAUSD_CUSTOM --time 1626984000 - ``` -5. Obtained price feed script value should be rounded leaving `rounding` number of digits after the decimal delimiter. If the next digit after `rounding` equals or is larger than 5, then price should be rounded up, otherwise it should be rounded down. In case the `rounding` parameter is not provided or it is not possible to interpret its value, voters should apply default rounding of 6 digits after the decimal delimiter. -6. Voters should use human judgement on whether the obtained results could be a reasonable estimation for the price of `base` token expressed in terms of `quote` currency and ensure that their results do not differ from broad market consensus. This is meant to be vague as the token-holders are responsible for defining broad market consensus, but some of example issues to check out are: - - Whether the passed price feed `configuration` has any implicit assumptions on the pegging of any trading pairs that do not hold true at the time of the price request that should be corrected accordingly (e.g. a stablecoin has lost its peg to USD). - - Whether an attempted price manipulation can be detected for any of involved trading pairs that should be corrected with additional price period protection (e.g. TWAP). Voters should apply special attention to this in case the value locked in the requesting contract is substantial relative to the liquidity in any of involved trading pair markets. - -In case of misconfiguration or lack of trading activity voters should resolve the price request in fallback mode following the below listed steps: -1. It might be possible that some data sources do not return price data for the requested timestamp due to lack of trading activity or any other technical reason causing the price feed script to fail. In case the price feed `configuration` contains alternative pricing routes for the same asset pair (e.g. when calculating median), voters should reconfigure it without the failing data source and attempt to calculate the requested price from the remaining data sources. -2. In case it is not possible to resolve the requested price either due to lack of trading activity in the specified markets or the `configuration` parameter being misconfigured, voters should attempt to resolve the price from the passed `fallback` parameter: - - Unless other guidance is provided in the `fallback` parameter, voters should assume that the provided endpoint should be queried for the price of `base` expressed in the `quote` currency. - - If `fallback` includes multiple price data endpoints for the same pair, the obtained prices should be medianized. - - If `fallback` includes price data endpoints for multiple pairs, the obtained prices should be combined in attempt to calculate `base` expressed in the `quote` currency. - - In case either `base` or `quote` are interest bearing, vault, liquidity pool or similar tokens that can be converted to their underlying token(s) at the smart contract level, but there are no direct trading markets for obtaining reliable price information, on-chain data should be used to express either `base` or `quote` tokens in terms of their underlying token(s) and then combine it with other pair pricing data from the provided endpoint(s) in the `fallback` parameter to obtain `base` expressed in `quote` currency. -3. In case the fallback mechanism is required, but the provided `fallback` parameter is misconfigured or the provided data endpoints become unavailable: - - Voters should attempt to identify relevant markets for involved trading pairs in order to calculate `base` expressed in units of `quote` using the guidance provided in step 7 above. - - In case the ancillary data passed does not allow to identify the requested `base` token, voters can assume `base` to be the collateral currency of the requesting contract if it allows to unambiguously identify it. Note that currently all financial contracts developed by UMA do have single collateral currency, but this might change in the future and Optimistic Oracle integrations are not restricted to UMA developed financial contracts. - - In case the ancillary data passed does not allow to identify the requested `quote` currency, voters can assume it to be USD (United States Dollar) by default. -4. In case of the lack of any available trading markets at the time of price request (e.g. due to delisting) UMA token holders should resolve the price request to zero. Though, the optionally passed `unresolved` parameter in the ancillary data might set any other non-zero fallback value that the voters should return as a last resort for otherwise unresolvable price request and voters should respect this fallback value to the extent it is unambiguously recognizable in the passed ancillary data. - -# Security considerations - -Anyone deploying a new contract referencing this TOKEN_PRICE identifier should take care to parameterize the contract appropriately to avoid the loss of funds for end users. Particularly, contract deployers should verify that running the price feed script with the passed `configuration` parameter in the ancillary data yields the expected price result before funding the contract. - -It is technically possible to launch a financial contract referencing this TOKEN_PRICE identifier before there is any trading market available by setting the price feed `configuration` parameter that should be expected to work at the time of the price request (e.g. either by guessing CEX trading pair identifier pattern or using deterministic pool addresses for Uniswap pairs). In this case both funders of such financial contracts and end users buying the minted synthetic tokens should accept the risk of loosing part or all of invested funds if there is no public trading market available at the time of price request and UMA voters have to resolve the price request to `unresolved` parameter or zero. - -The same risk scenario described above also applies to any other trading pair that had available markets at the time of deployment, but due to dried up liquidity or delisting there is no public pricing data available at the time of price request for UMA voters to resolve it. Hence, in case this TOKEN_PRICE identifier is used by DAO treasuries to sell derivative financial products backed by native project token, it should be the responsibility of project team to ensure that the native project token is listed with sufficient liquidity at the time of price request so that it can be resolved by UMA voters. End users buying such financial products should also carefully observe the availability of public trading data and evaluate the financial ability of project team to ensure adequate trading activity for its native project token. - -Even though currently this TOKEN_PRICE identifier would most likely be used in LSP contracts one could also use it in EMP contracts if they would support setting custom ancillary data in the future versions. In such scenario end users should take special care to verify the provided price feed configuration. For specific price identifiers UMIP reviewers and UMA voters are providing additional security layer, but for the generic TOKEN_PRICE identifier the responsibility to check price feed configuration is shifted on end users. Hence, before funding such contracts end users should verify that custom ancillary data is consistent, it includes valid and working price feed configuration, risk of sharp movements in price or market manipulation attacks is limited, as well as there is sufficient liquidity in collateral market allowing liquidators to purchase collateral and mint synthetic tokens to liquidate positions before the whole contract gets undercollateralized. - -The users of this TOKEN_PRICE identifier accept that its use can result in loss of funds either due to misconfiguration or external market conditions. Even though UMA holders are incentivized to use the best effort in resolving correct price requests, under no circumstances UMA token holders should be held liable for either not resolving price request or resolving price that differs from broader market consensus. diff --git a/research/uma/umips/umip-122.md b/research/uma/umips/umip-122.md deleted file mode 100644 index 39417a72..00000000 --- a/research/uma/umips/umip-122.md +++ /dev/null @@ -1,68 +0,0 @@ -# Headers - -| | | -|----------------|-------------------------------------------------------------------------------------------------------| -| UMIP Title | Add Polygon `DerivativeFactory` as `Creator` in DVM registry | -| Authors | Iliyan Iliev (iliyan.iliev@jarvis.exchange) | -| Status | Approved | -| Created | 28/07/2021 | -| Discourse link | https://discourse.umaproject.org/t/register-polygon-derivativefactory-as-creator-in-dvm-registry/1267 | - -# Summary - - -Reminder: Synthereum is a protocol to issue multi-collateralized synthetic fiat assets against liquidity pools.

As swap fees are a direct proxy for volume/volatility, there are many parties that would benefit if such a product existed. Two groups who would likely balance short and long interest, namely: - -**Potential short party**: Market makers, miners, MEV searchers, Sushiswap and xSushi holders (assuming sufficient liquidity) could hedge revenues by shorting this synthetic if they believe that volume is likely to decline as all parties have revenues correlated to volume. - -**Potential long party**: Speculators can take leveraged bets on the direction of swap fees/volume/volatility. The leverage is implicit as taking bets on the xSushi yield through this synthetic does not require the capital intensive depositing of Sushi in return for xSushi. - -# Data Specifications: - -All relevant price data is computed using information that can be found directly on the blockchain using an archive node. -* Price identifier name: `XSUSHI_APY` -* Example price providers: The relevant data can be obtained on-chain using an archive node: - * Alchemy (node) offers a free 25,000,000 compute units / month with archive node capability -* This information is also available on The Graph with the exact timestamps needed (UTC 00:00:00) -* Real-time price update frequency: Updated every day -* Historical price update frequency: Updated every day - -# Technical Specifications: - -* Price identifier name: `XSUSHI_APY` (5% expressed as 5 i.e not decimal format) -* Base Currency: XSUSHI APY -* Quote Currency: N/A -* Rounding: Round to 4 decimal places (fifth decimal place digit >= 5 rounds up and < 5 rounds down) - -# Rationale: - -xSushi yield was specifically chosen as it is much easier/cheaper to distort volume/swap fees in a single pool than across an entire AMM (current TVL of sushiswap is >$3bn at the time of writing). - -Another core consideration that led to using xSushi APY is that 0.05% of every swap fee of 0.3% is redirected to xSushi stakers. Meaning to generate $1 of fees for xSushi holders through trading, a trader will have to pay $6 in swap fees ($6 x 0.05%/0.3% = $1) significantly raising the cost of manipulation. - -Both methods above significantly reduce potential price identifier manipulation. - -# Price Feed Implementation - -The accounting methodology for xSushi is fortunately very simple. The Sushi generated from protocol revenue is deposited into a smart contract which all xSushi holders have a proportional share in. The ratio in which xSushi can be redeemed for Sushi is calculated by dividing the ever increasing Sushi balance in the xSushi smart contract by the number of xSushi tokens in circulation. - -The `XSUSHI_APY` price would require the creation of a new price feed.

To do this, voters should use the open price of the OHLC period that the price request timestamp falls in.

They are popular with Quantitative Traders, Fintech companies and Institutional customers who require a high quality and trusted feed. - -### Weekend timestamp - -Over the weekend or some official holidays the REST API does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). - -Due to unavailability of price feed for foreign exchange rates and commodities over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as a official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation). A reference TraderMade implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/TraderMadePriceFeed.ts). - -Our team has adjusted the original Liquidation and Dispute bots in order to fit the interfaces of our protocol.

Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. diff --git a/research/uma/umips/umip-128.md b/research/uma/umips/umip-128.md deleted file mode 100644 index b89235ef..00000000 --- a/research/uma/umips/umip-128.md +++ /dev/null @@ -1,42 +0,0 @@ -## Headers -UMIP-128 - -- UMIP title: Add DFX as a Polygon collateral currency -- Author: Chandler (chandler@umaproject.org) -- Status: Approved -- Created: 10 September 2021 - -## Summary (2-5 sentences) - -This UMIP proposes adding **DFX** for use as collateral in UMA contracts for the Polygon Network.

The process we use is: - - Scan through all of the `PunkBought` events and identify the function call that generated the `PunkBought` event: - - If it was generated by `buyPunk` then use the `PunkBought.value` price - - If it was generated by `acceptBidForPunk` then we load all of the `PunkBidEntered` for that particular CryptoPunk and use the most recent bid (only one bid can be outstanding at a time and is always the highest) - - In both cases, we ignore any trades that are registered with a price of 0 and look back to the most recent non-zero price. -3. Take the median of these prices - If there is an even number of prices, take the mean of the two values closest to the median. -4. Divide by 1000, and then round to 6 decimals to arrive at the final price. - - -**Example** - -If the timestamp requested was `1619222400` then: - -* We would need to identify all `PunkBought` events from `1619222400 - 30 days -> 1616630400` to `1619222400` -* Imagine that we had 5 `PunkBought` events with (`ts`, `punk_id`, `eth`) pairs of `[(1616630450, 1000, 20), (1616631450, 5000, 30), (1616631550, 5000, 35), (1618631550, 6000, 22), (1618632550, 9999, 15)]`. -* We would need to check what function generated each `PunkBought` event. Suppose they were all generated by `buyPunk`, then the prices we would use to compute the median would be `[20, 35, 22, 15]` -* There are an even number of values, so there's no "median value" in the data -- Thus we find the number between the two values closest to the median `[20, 22]` to get a price of `21` -* Divide by `1000` to get a price of `0.021` - -### Before Expiry - -When a price request that relies on this price identifier is made, the following process should be followed: - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp - TWAP period (2 hours). -3. A single Uniswap/Sushiswap price is defined for each timestamp as the price that the ETH/uPUNK pool returns at the end of the latest block whose timestamp is less than or equal to the timestamp that is queried for. -4.

An individual who owns 400 CryptoPunks and traded them amongst their own accounts at prices near zero could corrupt the price by driving it to zero after having minted and sold the tokens at a high price. - -One benefit to using an oracle with human intervention is that voters could recognize this type of price manipulation and there are other viable proxies for the expected price of a CryptoPunk. For example, if voters felt like there was price manipulation, they could choose to settle the contract at the current market price of `PUNKBASIC` or other - -The other main concern is if there were just insufficient CryptoPunk trades being made. If there were only 1-2 trades happening every 30 days, this index becomes much less useful because there's less information contained in its price. - -### Before Expiry - -The main concerns of the TWAP price are: - -1. **Token price manipulation**: If the Uniswap pool is not sufficiently liquid, then attackers could try to drive down the Uniswap price and withdraw more collateral than intended. Most DeFi attacks have been done using flash loans, but flash loans would be ineffective since the price is measured at the end of each block. Collateralizaton based on the TWAP price would make it more capital intensive (and thus risky) to target the token price in this way. -2. **TWAP mismatch**: If the price of the token rises quickly then there would become a mismatch between the market price and the TWAP price. This might allow sponsers to mint tokens with less collateral than what they could sell them for on the market. Reasonable levels of collateralizaton requirements and the 2 hour "liveness period" help combat this concern. - -Both of these concerns are originally discussed in [UMIP 22](./umip-22.md) diff --git a/research/uma/umips/umip-131.md b/research/uma/umips/umip-131.md deleted file mode 100644 index e65483db..00000000 --- a/research/uma/umips/umip-131.md +++ /dev/null @@ -1,69 +0,0 @@ -## Headers -UMIP-131 - -- UMIP title: Add miMATIC, VOL, BIFI, ICE, IRON and IF as supported collateral currencies -- Author: Chandler (chandler@umaproject.org) -- Status: Approved -- Created: 13 September 2021 - - -## Summary (2-5 sentences) - -This UMIP proposes adding **miMATIC**, **VOL**, **BIFI**, **ICE**, **IRON** and **IF** for use as collateral in UMA contracts. - -## Motivation - -The addition of this collateral currency offers additional functionality to the UMA protocol and increases the range of contracts that can be built. - -miMATIC also known as MAI is a soft pegged stablecoin that is backed by other assets in the Polygon network. - -## Technical Specification - -To accomplish this upgrade, the following changes needs to be added to the collateral currency whitelist introduced in UMIP-8. - -## Ethereum -### VOL token -- The **VOL** Ethereum [token address](https://etherscan.io/token/0x5166e09628b696285e3a151e84fb977736a83575): 0x5166e09628b696285e3a151e84fb977736a83575 -- A final fee of **1200 VOL** needs to be added in the Store contract. - -### IF (Impossible Finance) - - The **IF** Ethereum [token address](https://etherscan.io/token/0xb0e1fc65c1a741b4662b813eb787d369b8614af1): 0xb0e1fc65c1a741b4662b813eb787d369b8614af1 - - A final fee of **250 IF** needs to be added in the Store contract. - -## Polygon -### miMATIC token -- The **miMATIC** Polygon [token address](https://polygonscan.com/token/0xa3fa99a148fa48d14ed51d610c367c61876997f1): 0xa3fa99a148fa48d14ed51d610c367c61876997f1 -- A final fee of **400 MAI** needs to be added in the Store contract. - -### BIFI token -- The **BIFI** Polygon [token address](https://polygonscan.com/token/0xfbdd194376de19a88118e84e279b977f165d01b8): 0xfbdd194376de19a88118e84e279b977f165d01b8 -- A final fee of **0.5 BIFI** needs to be added in the Store contract. - -### ICE token (Iron Finance) -- The **ICE** Polygon [token address](https://polygonscan.com/token/0x4A81f8796e0c6Ad4877A51C86693B0dE8093F2ef): 0x4A81f8796e0c6Ad4877A51C86693B0dE8093F2ef -- A final fee of **23 000 ICE** needs to be added in the Store contract. - -### IRON stablecoin - - The **IRON** Polygon [token address](https://polygonscan.com/token/0xD86b5923F3AD7b585eD81B448170ae026c65ae9a): 0xD86b5923F3AD7b585eD81B448170ae026c65ae9a - - A final fee of **400 IRON** needs to be added in the Store contract. - -## Rationale - -This store fee was chosen as it is approximately equivalent to $400 in line with other collateral currencies as determined by assuming that the MIA and IRON tokens will hold its peg to $1 per token or by using CoinMarketCap and CoinGecko prices. - -## Implementation - - -This change has no implementations other than the aforementioned governor transactions - -## Security considerations - -Adding a collateral currency introduces a level of risk into the UMA Ecosystem.

The idea is to have smart contract security experts assess/price protocol coverage, then get paid based on the performance of the protocols (no hacks = large payout, large hack = no payout). Protocols who want coverage will pay Sherlock monthly premiums, and in return, Sherlock will use it’s staking pool to repay hacks at protocols. Sherlock is doing a guarded launch with $30M in staking pool funds and writing coverage for up to $10M per protocol. More details can be found here. - -Other exploit protection protocols rely on their tokenholders to decide whether claims should be paid out or not. Sherlock wants to do better and would like to use UMA’s Data Verification Mechanism as the final escalation to decide on claims payouts. This would help coverage buyers feel more comfortable that they have access to an unbiased party’s decision on a claim. - -For context, Sherlock agrees on coverage terms with every protocol. An example can be seen here (TBA). These terms will be broadly the same across all protocols but there may be extra language added for protocol-specific exploit risks. - -In the event of a potential exploit, Sherlock’s security team will work with the protocol to determine the nature of a hack. If the protocol believes they experienced an exploit that should be covered by Sherlock, the protocol will submit the block range of the exploit and the amount to be reimbursed by Sherlock. Next, Sherlock’s claims committee (made up of reputable security experts associated with Sherlock such as [John Mardlin](https://twitter.com/maurelian_), [Mariano Conti](https://twitter.com/nanexcool), and [Rajeev Gopalakrishna](https://twitter.com/0xRajeev)) will work to evaluate the nature of the potential exploit and then map the exploit to the coverage terms agreed to with that protocol. The committee will then decide whether to pay out the claim. If the committee decides not to pay out the claim, the protocol has the option to stake a minimum dollar amount ($50k for example) and escalate the claim to the UMA Data Verification Mechanism. The UMA tokenholders would then use information provided by the protocol, the claims committee, and importantly, security expert not associated with Sherlock, to decide whether the claim should be paid out or not. - -Relying on UMA’s DVM for claims decisions will significantly increase the value of on-chain exploit protection mechanisms in the eyes of protocols and end users. One of the biggest hurdles to adoption of coverage is the biased nature of claims processes. Sherlock believes that the involvement of UMA’s DVM will make exploit protection protocols more trustworthy and further normalize adoption of coverage by protocols and end users alike. By adding this product, UMA can blaze a trail that contributes to the safety of DeFi. Sherlock would love to set a precedent with UMA for how exploit claims disputes should be resolved on-chain. - -## Ancillary Data Specifications - -``` -Metric:Sherlock exploit claim arbitration, -Protocol:, -ChainId:, -Value:, -StartBlock:, -Resources:, -CoverageAgreement: -``` - -Example: -``` -Metric:Sherlock exploit claim arbitration, -Protocol:UMA Protocol, -ChainId:1, -Value:1000000, -StartBlock:13207345, -CoverageAgreement:Link to protocol specific coverage agreement with Sherlock -``` - -For guidance on how to structure ancillary data correctly, refer [here](https://docs.umaproject.org/uma-tokenholders/guidance-on-adding-price-identifiers#ancillary-data-specification). - -## Rationale and usage - -The framing of the price identifier puts the responsibility on the protocol to specify the correct blocktime, blockchain, and payout amount in order to receive a payout. If any of the information is not accurate, a payout will not occur. This is mitigated by the idea that a protocol will get up to 3 chances to correctly input the data in order to successfully trigger a payout. - -Because the potential request space is broad, it is possible that voters will not be able to arrive at a definitive result. In this case, the default return value should be “unresolvable” (or 0.5), which likely will also result in no payout from Sherlock to the claimer. This places the onus on the protocol to provide clear evidence that an exploit occurred. Practically from the Sherlock side, a returned value of 0.5 or 0 will make no difference, as neither will change the committee's "no payout" outcome. - -It is low risk for UMA voters to return a value of 0.5, as it is likely that this will result in a resubmission of the price request by the claiming protocol once they have have accumulated more concrete evidence of their claim. If a claim is paid out in error, there is little recourse for Sherlock at that point, so it seems reasonable that a protocol should have to prove that a payout occurred and that the default should be “no action”, meaning a payout is not enacted. - -## Implementation - -1. Voters should decode the ancillary data and identify the protocol, chain, start block, dollar value of claim in question and any additional resources provided. -2. Because the protocol making the claim will likely be the party constructing the ancillary data and submitting a price request, voters should heavily rely on checking external resources for additional context. The Sherlock Coverage Terms Agreement should always be referenced. Additionally the Protocol's original claim as well as the Sherlock Claims Committee's original claims decision will likely always be published and should be referenced. Sherlock's Coverage Agreement details the exact types of exploits that Sherlock covers, and these should be the only exploits that are considered in arbitration. More information is provided in the `Additional Resources` section below. -3. Voters should return a value of `1` if they determine that: - 1. There was an exploit for the `Protocol` specified. - 2. The exploit type is covered by Sherlock's Coverage Agreement. - 3. The exploit happened as part of the `StartBlock` specified in ancillary data. - 4. The total USD value lost in the exploit is greater than or equal to the USD `Value` within ancillary data. -4. If voters can confidently identify that one of the above is not correct, they should return a value of `0`. -5. If voters cannot confidently assess one of the criterion above, they should return a value of `0.5` (cannot be resolved). - -## Additional Resources -While the coverage agreement document between Sherlock and the protocol in question will serve as the canonical guideline as to whether an exploit falls under coverage or not, it is non-trivial to determine whether an exploit occurred, and how that exploit maps to the coverage agreement. - -Outside of the coverage agreement, UMA tokenholders should rely on 3 sources of information when making their decision: -1) The interpretation of the exploit and coverage agreement by the Sherlock claims committee and other persons associated with Sherlock. -2) The interpretation of the exploit and coverage agreement by the protocol in question. -3) Most important, the interpretation of the exploit and coverage agreement by third party security experts. - -While information in 1) and 2) should be readily available (both parties will be motivated to explain their interpretation), we can reasonably expect 3) to be readily available as well based on historical public interest in protocol exploits and past articles produced. - -Sources of 3) could be [rekt.news](https://twitter.com/RektHQ), [Mudit Gupta](https://twitter.com/Mudit__Gupta), [Kelvin Fichter](https://twitter.com/kelvinfichter), [Igor Igamberdiev](https://twitter.com/FrankResearcher), as well as audit firms such as [PeckShield](https://twitter.com/peckshield) as long as the parties don’t have material connection to either Sherlock or the protocol in question. - -## Security Considerations - -It should be noted that this price identifier is objectively complex and broad and will likely require a large amount of active participation from UMA voters to correctly analyze and resolve these requests. UMA voters should not be expected to be security experts, and therefore do not accept any liability from potential claims from either the claiming protocol or Sherlock. UMA voters should only be expected to act as an impartial jury; their responsibility is to synthesize information from ancillary data, `Additional Resources`, Sherlock's coverage terms and ad hoc information provided by Sherlock and the claiming protocol during arbitration, but not to perform complete security analysis themselves. - -There are also several mitigating processes built into the Sherlock system as well as the UMA voting system. As noted previously, claiming protocols will have up to 3 total chances to submit claims and go to a DVM vote. This should allow for comprehensive information gathering and analysis, and will allow UMA voters to default to an "unresolvable" return value unless clear supporting evidence is provided either to support or contradict a claim. - -The DVM voting system also allows for a multi-day discussion and information gathering process. Because of this reason, it seems acceptable that the potential price request space for this identifier is broad and potentially subjective. Both the claiming protocol, as well as Sherlock's security committee will have the opportunity to provide supporting evidence and advocate for their case. It is recommended that both parties be active in UMA's #voting [Discord channel](https://discord.gg/YE4h2YAb), as this is where most UMA voting discussion occurs. diff --git a/research/uma/umips/umip-133.md b/research/uma/umips/umip-133.md deleted file mode 100644 index 80a52c58..00000000 --- a/research/uma/umips/umip-133.md +++ /dev/null @@ -1,47 +0,0 @@ -## Headers -UMIP-133 - -- UMIP title: Add PERP, GRO and POOL as collateral currency -- Author: Chandler (chandler@umaproject.org) -- Status: Approved -- Created: 28 September 2021 - -## Summary (2-5 sentences) - -This UMIP proposes adding **PERP**, **POOL** and **GRO** for use as collateral in UMA contracts. - -## Motivation - -The addition of this collateral currency offers additional functionality to the UMA protocol and increases the range of contracts that can be built. - -## Technical Specification - -To accomplish this upgrade, the following needs to be added to the collateral currency whitelist introduced in UMIP-8. - -### PERP -- The **PERP** Ethereum [token address](https://etherscan.io/token/0xbc396689893d065f41bc2c6ecbee5e0085233447): 0xbc396689893d065f41bc2c6ecbee5e0085233447 -- A final fee of **35 PERP tokens** needs to be added in the Store contract. - -### GRO -- The **GRO** Ethereum [token address](https://etherscan.io/address/0x3ec8798b81485a254928b70cda1cf0a2bb0b74d7): 0x3ec8798b81485a254928b70cda1cf0a2bb0b74d7 -- A final fee of **35 GRO tokens** needs to be added in the Store contract. - -### POOL -- The **POOL** Polygon [token address](https://polygonscan.com/address/0x25788a1a171ec66da6502f9975a15b609ff54cf6): 0x25788a1a171ec66da6502f9975a15b609ff54cf6 -- A final fee of **45 POOL tokens** needs to be added in the Store contract. -## Rationale - -This store fee was chosen as it is approximately equivalent to $400 in line with other collateral currencies as determined by using the average price observed on Coinmarketcap. - -## Implementation - - -This change has no implementations other than the aforementioned governor transactions - -## Security considerations - -Adding a collateral currency introduces a level of risk into the UMA Ecosystem.

This should match the `relayAncillaryData` field emitted by the `BridgePool` in the [DepositRelayed](https://github.com/UMAprotocol/protocol/blob/b588e83ca548a2a0d59b36f02ec9800afce28dec/packages/core/contracts/insured-bridge/BridgePool.sol#L135-L141) event. If no event exists with that hash, the relay is invalid. - -In the same event, the voter should see a `depositData` field containing `DepositData` struct. The `DepositData` struct should contain a `chainId` field. This field should be used to call `depositContracts(chainId)` on the `BridgeAdmin` contract (called at the latest block number at or before timestamp from `quoteTimestamp` field in the `DepositData` struct) and take the `depositContract` value in the struct (first element). This should be the deposit contract address on the chain specified by the chainId (arbitrum or optimism). The voter should query this contract for the [FundsDeposited](https://github.com/UMAprotocol/protocol/blob/b588e83ca548a2a0d59b36f02ec9800afce28dec/packages/core/contracts-ovm/insured-bridge/implementation/BridgeDepositBox.sol#L73-L84) event to verify that its fields match the corresponding `DepositData` struct fields on mainnet exactly. If there is any difference, the relay is invalid. - -In the `RelayData` struct in the DepositRelayed event queried earlier, there is a field called `realizedLpFeePct`. Note: the `RelayData` struct is called `relay` in the event, and to decode the `realizedFeePct` field, one may need to decode with web3.js/ethers and extract the 4th field, since structs are sommetimes decoded as tuples rather than a struct with named fields. This field is specifified by the relayer and needs to be computed using the `quoteTimestamp` specified in the `depositData`. The algorithm for computing the `realizedLpFeePct` is specified below where: - -* $X$ denotes the size of a particular transaction someone is seeking to bridge -* $0 \leq U_t \leq 1$ denotes the utilization of the liquidity providers' capital prior to the transaction, i.e. the amount of the liquidity providers' capital that is in use prior to the current transaction -* $0 \leq \hat{U}_t \leq 1$ denotes the utilization of the liquidity providers' capital after to the transaction, i.e. the amount of the liquidity providers' capital that would be in use if the user chose to execute their transaction -* $\bar{U}$ denotes the "kink utilization" where the slope on the interest rate changes -* $R_0, R_1, R_2$ denotes the parameters governing the interest rate model slopes: - * $R_0$ is the interest rate that would be charged at 0% utilization - * $R_0 + R_1$ is the interest rate that would be charged at $\bar{U}\%25$ utilization - * $R_0 + R_1 + R_2$ is the interest rate that would be charged at 100% utilization - -An interest rate at any given amount of utilization would be given by the following equation: - -$R(U_t) = R_0 + \frac{\min(\bar{U}, U_t)}{\bar{U}} R_1 + \frac{\max(0, U_t - \bar{U})}{1 - \bar{U}} R_2$ - -In our case for a loan, we must integrate over a range of utilizations because each dollar of the loan pushes up the interest rate for the next dollar of the loan. This effect is captured using an integral: - -$R^a_t = \int_{U_t}^{\hat{U}_t} R(u) du$ - -To get the true rate charged on these loans, we need to de-annualize it to get the percentage: - -$R^w_t = \min \left( (1 + R^a_t)^{\frac{1}{52}} - 1, 1 \right)$ - -which bounds the LP fee to being less than or equal to 100% of the transfer amount. - -$U_t$ can be fetched on-chain by calling `liquidityUtilizationCurrent` method on the `BridgePool` contract at the latest available block number at or before the `quoteTimestamp`. $\hat{U}_t$ can be fetched by calling `liquidityUtilizationPostRelay` method on the `BridgePool` contract at the same block number passing the `amount` field from the `DepositData` struct as `relayedAmount` parameter. Normally the `BridgePool` contract for calling these methods should be the same as the `requester`, but in the unlikely scenario when `BridgePool` gets migrated with pending deposits on L2 one should calculate the utilization ratio on the `BridgePool` contract that was active at the time of `quoteTimestamp`. In order to identify the previous `BridgePool` one should look up the last `WhitelistToken` event emitted by the deposit contract on L2 before the relayed transaction's `quoteTimestamp` and use the address from event's `bridgePool` field. - -Since the notion of `block.timestamp` might be different on other L2 chains compared to main ethereum L1 EVM, deposit contracts on L2 allow setting the `quoteTimestamp` within 10 minute range from current time. In order to deterministically calculate LP fees based on pool utilization ratio the relayer should wait until L1 block timestamp reaches the `quoteTimestamp`. Any relayed transaction that is mined with earlier block timestamp than `quoteTimestamp` field from `DepositData` struct in the `DepositRelayed` event should be invalid. - -Please see the example [implementation](https://github.com/UMAprotocol/protocol/blob/b588e83ca548a2a0d59b36f02ec9800afce28dec/packages/sdk/src/across/feeCalculator.ts#L78-L82)) for more details. - -The rate model parameters used for the above computation should be fetched on-chain from the `RateModelStore` contract deployed on mainnet at [0xd18fFeb5fdd1F2e122251eA7Bf357D8Af0B60B50](https://etherscan.io/address/0xd18fFeb5fdd1F2e122251eA7Bf357D8Af0B60B50) and governed by Across protocol [multi-signature account](https://etherscan.io/address/0xb524735356985d2f267fa010d681f061dff03715). Rate model parameters should be fetched by calling `l1TokenRateModels` method on the `RateModelStore` contract passing `l1Token` address as its argument at the block whose timestamp corresponds or is the latest available relative to the `quoteTimestamp` field. - -The call to `l1TokenRateModels` should return a stringified JSON object containing the following key-value pairs: -* `UBar` corresponds to the $\bar{U}$ rate model parameter; -* `R0`, `R1` and `R2` correspond to $R_0$, $R_1$ and $R_2$ parameters respectively. - -Rate model parameter values obtained above should be scaled down by 18 decimals. - -In case the call to `l1TokenRateModels` returns anything that cannot be parsed to the exact key-value pairs mentioned above (e.g. missing or extra parameter included) the relay should be considered invalid. - -If the algorithm above doesn't produce a matching `realizedLPFeePct` (after floor rounding the result expressed as decimal to 18 decimals), the relay is invalid. If the token is not listed in the table above, the relay is invalid. - -If the relay is invalid, the price should be `0`. If the relay is valid, it should be `1`.

Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not, the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different from the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as an official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation). A reference TraderMade implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/TraderMadePriceFeed.ts). - -Our team has adjusted the original Liquidation and Dispute bots in order to fit the interfaces of our protocol. You can find our versions of the Liquidator and Dispute bots on the following GitLab links: - -- [Liquidator Bot](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jrv_bot/packages/liquidator/test) -- [Dispute Bot](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jrv_bot/packages/disputer/test) - -TraderMade is provided as an accessible source to query for this data, but ultimately how one queries for these rates should be varied and determined by the voter to ensure that there is no central point of failure. - -In the case of a TraderMade outage voters can turn to any other available price feed API or a broker API, as the price feeds for the forementioned financial assets does not differ much between different providers. There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes. For this case, we provide options for additional price feed providers that voters could utilize. - -## Additional price feed providers - -### FXMarketAPI - -Documentation for the API can be found [here](https://fxmarketapi.com/documentation#live_rates). - -- Live price feed data -- Historical prices based on date and time -- Registration is free and provides 500 free requests -- Paid plans available -- OHLC request can be used to grab the last closing price before a weekend or a non-working day - -Example requests: - -- Live Rate for AUDUSD: `https://fxmarketapi.com/apiliveapi_key=api_key¤cy=AUDUSD` -- OHLC for a certain date on a currency pair: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=AUDUSD&date=2020-12-23&format=ohlc` -- Request for AUDUSD price at a certain date and time: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=AUDUSD&date=2020-12-23-15:50` - -### FCS API - -Documentation for the API can be found [here](https://fcsapi.com/document/forex-api). - -- 500 API Calls with Free Plan -- Live price data accessible with Free Plan - Updated every 60 seconds or less -- Historical data accessible with the Basic Paid Plan - 10$ per month - -Example requests: - -- Live Rate for AUD/USD: `https://fcsapi.com/api-v3/forex/latest?symbol=AUD/USD&access_key=api_key` -- Historical price for a certain date for AUD/USD - gives back the OHLC: `https://fcsapi.com/api-v3/forex/history?symbol=AUD/USD&period=1D&from=2020-12-23&to=2020-12-24&access_key=api_key` -- Price of AUD/USD between certain dates and times - gives a breakdown on the price each 1 minute between 12:00 and 12:30: `https://fcsapi.com/api-v3/forex/history?symbol=AUD/USD&period=1M&from=2020-12-23T12:00&to=2020-12-23T12:30&access_key=api_key` - -## Security considerations - -Adding this new identifier by itself poses a little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of AUDUSD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap on AUD/USD, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidations and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. diff --git a/research/uma/umips/umip-14.md b/research/uma/umips/umip-14.md deleted file mode 100644 index e588ddeb..00000000 --- a/research/uma/umips/umip-14.md +++ /dev/null @@ -1,63 +0,0 @@ -## Headers -| UMIP-14 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Approve Updated EMP Financial Contract Template | -| Authors | Nick Pai (nick@umaproject.org) | -| Status | Approved | -| Created | September 16, 2020 | - -## Summary -This UMIP will have the effect of introducing an upgraded expiring financial contract template that: -1. Updates the `ExpiringMultiPartyCreator` factory contract's restrictions on liveness periods and the expiration timestamp. -2. Relaxes `ExpiringMultiParty`'s token creation collateralization requirements. -3. Adds additional power for under-funded liquidators to deter malicious sponsors with large position sizes. -4. Supports collateral currencies that accumulate interest, like [aTokens](https://docs.aave.com/developers/developing-on-aave/the-protocol/atokens#redirectintereststream) which redirect interest to a target address. -5. Enables redemptions post-expiry and most importantly, during the two day expiry price resolution pricess. - -## Motivation & Rationale - -This UMIP was motivated by a combination of user comments and economic attack surface considerations. - -## Technical Specification -To accomplish this upgrade, a new financial contract template must be deployed. - -After deployment, this new `ExpiringMutltiPartyCreator` contract should be approved as a ContractCreator in the Registry. - -Note: the voters only vote for the approval -- the deployment has no effect on the protocol until added as a ContractCreator. - -**The specific changes in detail comprise:** - -1. Updating EMPCreator restructions: - - The EMPCreator should explicitly enforce that expiration times are in the future. The EMP itself already enforces this, but the creator's `deploy` function should revert earlier if the deployer attempts to pass an expiration time in the past. - - This update also places a hard-cap on the liquidation liveness and withdrawal liveness parameters. Currently, the applied changes allow setting arbitrarily large values, which could cause undesired reverts due to overflows. - -2. Relaxing token creation collateralization requirements: - - The UMA price oracle requires a novel mechanism to guarantee user collateralization despite not having direct access to the real-time price of the collateral. The Global Collateralization Ratio (GCR) is used as a substitute, since it would be an overestimate of the required value under some reasonable economic assumptions. Whenever a new position is opened, the user is required to match this GCR with the corresponding new collateral. - - However, this may be unnecessarily restrictive, since the collateralization ratio of each change in the position is not individually relevant. Users have criticized, rightfully, the bad UX requiring an over-collateralized sponsor to always create new tokens in a ratio above the GCR, even if their existing position is already well above the GCR. **This update relaxes the requirement to ensure that either the final user position matches the GCR, or the new collateral and minted tokens match the GCR (as before)**. - -3. Empowering under-funded liquidators: - - When a withdrawal that would put a position below the Global Collateralization Ratio is requested, liquidators have a time window to liquidate the position if the withdrawal is invalid. However, if the position is sufficiently large, it may be difficult for liquidators to (collectively) obtain enough synthetic tokens within the allotted time window. - - This update resets the withdrawal time window whenever a partial liquidation that is sufficiently large occurs within the window. It should be noted that although this mechanism can be used to delay valid withdrawals, potentially until expiration, it does not remove the usual penalty associated with false liquidations, which would have to be paid for every delaying transaction. - -4. Supporting new collateral currency types: - - Developers want to be able to deploy EMP's collataralized by aTokens. A new `trimExcess()` method is added to the EMP so that aToken interest can be redirected to an external contract. - -5. Enabling redemptions post-expiry: - - After an EMP contract expires, collateral is locked within the contract while an expiry price is resolved by the UMA oracle voters. This places extra price risk on sponsors. - - This pull request removes the time restriction on the `redeem` function so it can be called even after the contract expires and enables them to redeem a proportional amount of collateral to their synthetic tokens burned. It also allows the `cancelWithdrawal` function to be called after expiration, so that a pending slow withdrawal will not stall the token redemption. - -## Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/core/contracts/financial-templates/expiring-multiparty).

-The purpose of this price identifier is to create synthetic token, price of which is linked to the value of index of **10** most active SPACs (Special Purpose Acquisition Companies) shares.
That synthetic token can be used for creating speculative strategies at IPO market. - -## MOTIVATION -A synthetic token that tracks the index of the 10 most active SPACs stocks can be used for speculative purposes and allows the user to earn on price movements in one of the most interesting markets without centralized intermediaries such as exchanges and brokers.
-In addition, that token can be used as components associated with classical markets by other DeFi and DApp protocols, which makes it possible to scale. - -## TECHNICAL SPECIFICATION -| | | -|:---------------------------|:---------------------------------------------------| -|**Identifier name** |**uSPAC10**| -|Base asset | Most active SPAC shares.| -|Quote Currency | USD| -|Intended Collateral Currency| USDC| -|Market | NYSE, NASDAQ| -|Source |["Stock Data – Rapidapi.com"](https://rapidapi.com/principalapis/api/stock-data-yahoo-finance-alternative/), API - Cost to use: Free 1000 requests per month, [Pricing](https://rapidapi.com/principalapis/api/stock-data-yahoo-finance-alternative/pricing)| -|Scaling Decimals | 18 (1e18)| -|Rounding | Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down)| - -## RATIONALE -Special Purpose Acquisition Companies (“SPACs”) are companies formed to raise capital in an initial public offering (“IPO”) with the purpose of using the proceeds to acquire one or more unspecified businesses or assets to be identified after the IPO (irrespective of form, a “Business Combination”). SPACs have only a limited period during which they may consummate a Business Combination, generally not exceeding 24 months. A SPAC generally focuses upon one industry or sector, but may maintain flexibility to engage in transactions in other industries or sectors if necessary or appropriate. More information about SPACs can be found [here](https://spac.guide/spacbasics/) and [here](https://www.spacanalytics.com/).

-`A good way to capitalize on such momentum growth without having to analyze hundreds of SPACs is to take advantage of the movement of the index value that includes stocks of the most active SPACs.`
- -The selection of **10** stocks of the most active SPACs included in the basket of the proposed uSPAC10 index is made according to [SPAC Analytics Top Performing SPACs](https://www.spacanalytics.com/).
->SPAC Analytics is the leading provider of SPAC data and research to portfolio managers and investment banks since 2007. - -These underlying assets are traded on the NYSE and NASDAQ, but reliable sources of quotations are either paid or provide data with a delay.
-We suggest using the ["Stock Data – Rapidapi.com"](https://rapidapi.com/principalapis/api/stock-data-yahoo-finance-alternative/) API as the main source of quotes, which has both free and paid tariff plans, and also provides historical price data. - ->Stock Data – Rapidapi.com is a decision for retrieving real time stock data. Alternative to the Yahoo Finance API. Rapidapi.com Finance APIs allow end-users a variety of service options for their accounts as well as to stay current on events and news that impact their portfolios and financial security. For example, a finance API could remotely connect them to their bank account to initiate deposits, transfers, or other transactions. Other financial APIs include stock market news and trading platforms, cryptocurrency markets, and more. A financial API provides a secure link from a consumer to the databases and transactional servers of the institutions with which they do business. Application programming interfaces, or APIs, are the digital links between data providers and end-users. In the financial sector, security is essential as sensitive information is transferred in real-time, so only the most robust protocols are utilized to protect the data transmitted on both ends. - -Underlying stocks are traded during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. - -## IMPLEMENTATION -### Price Identifier -The index basket is formed by including the first 10 stocks from the Top Performing SPACs table from the website [SPACanalytics.com](https://www.spacanalytics.com/) on 30.06.2022. -The list of stocks included in the index basket are: -|N|TICKER|MARKET| -|:--:|:------:|:--------:| -| 1|DWAC|NASDAQ| -| 2|IRDM|NASDAQ| -| 3|MP |NYSE | -| 4|PRIM|NASDAQ| -| 5|WSC |NASDAQ| -| 6|SMPL|NASDAQ| -| 7|TGLS|NASDAQ| -| 8|CERE|NASDAQ| -| 9|KW |NYSE | -|10|HPK |NASDAQ| -

Evaluate index value -2.1. Sum up quotes of all N SPAC shares included in index.
-2.2. Divide result by N (number of shares in index basket).
-``` - SumUp (Qi) -INDEX = ------------------ * K - N -``` -where: -- Qi - quote of Share i in index;
-- N - number of shares in index. **N = 10**
-- K - Correction factor, used to smooth the index values when the basket is changed. For the current index bucket **K = 0,95951**. The value of K changes when the index basket changes and is calculated in accordance as quotient of division INDEXold by INDEXnew:
-``` - INDEXold 26,846 - K = ------------ = ------------ = 0,95951 - INDEXnew 27,979 -``` -where: -- INDEXold – the last index value calculated from the old basket on 30.06.2022;
-- INDEXnew – the first index value calculated for the new basket at the same time as INDEXold;
- -> In order to index can reliably reflect the market picture, a periodic change of the basket of stocks included in the index is required. Therefore, we will publish a new price identifier quarterly. - -### Weekend timestamp -Over the weekend or some official holidays the REST API does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). -Due to unavailability of price feed for stock exchange rates over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. -If a request timestamp takes place on a weekend or any other day the stock market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. -### Stock markets working hours -Underlaying assets trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. -### Price feed -Our price-feed provider’s API documentation can be found [here](https://rapidapi.com/principalapis/api/stock-data-yahoo-finance-alternative/).
-A reference price feed implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/unisxapp/protocol/blob/USPAC5PriceFeed/packages/financial-templates-lib/src/price-feed/DefaultPriceFeedConfigs.ts)
-"Stock Data – Rapidapi.com" is provided as an accessible source to query for this data, but ultimately how one queries for these rates should be varied and determined by the voter to ensure that there is no central point of failure.
-In the case of a "Stock Data – Rapidapi.com" outage voters can turn to any other available price feed API or a broker API, as the price feeds for the forementioned financial assets does not differ much between different providers. There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes. For this case, we provide options for additional price feed providers that voters could utilize. -### Additional price feed providers -- **Yahoo Finance – Rapidapi.com**

The hub collects messages sent between an "oracle spoke" deployed on any non-mainnet EVM networks and the DVM on mainnet, and therefore it must be approved to submit price requests to the DVM. It might be helpful to review [this UMIP](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-113.md) that approved an "oracle root tunnel" that specifically sent messages between Polygon and Ethereum. The oracle hub is similar to the root tunnel except that it can be used for other EVM networks besides Polygon and it can communicate with many networks at the same time, hence why its referred to as an N-to-1 "hub" and not a 1-to-1 "tunnel". - -# Cross Chain Infrastructure -[This folder](https://github.com/UMAprotocol/protocol/tree/34f3180b48397a2ba9211cc6fae33a327b9cb165/packages/core/contracts/cross-chain-oracle) contains contracts that are built on top of bridge protocols to enable UMA's Optimistic Oracle and -Governance contracts to send messages across EVM networks. - -## Hub and Spoke Architecture -*Hub and *Spoke contracts are included that are respectively deployed on "Parent" and "Child" networks. As the Hub -and Spoke names imply, one Hub is designed to service many Spokes. For example, the `OracleHub` can broadcast price -resolutions from the DVM on mainnet to any number of `OracleSpoke` contracts on other EVM networks like Polygon, -Arbitrum, Optimism, and more. Similarly, the `GovernorHub` can be used by the DVM to send governance transactions to -any number of `GovernanceSpoke` contracts on other EVM networks. - -Hub and Spoke contract implementations are network agnostic, but Messenger contracts are network-specific because -they are the contracts that actually send intra-network messages. - -## Parent and Child Messengers -*Hub and *Spoke contracts communicate via a Parent-Child tunnel: a `ParentMessenger` contract is always deployed -to the network that the *Hub contract is deployed to, and the `ChildMessenger` contract is always deployed to the -*Spoke contract's network. - -So, *Hub and *Spoke contracts have a "1-to-N" relationship, and each *Hub and *Spoke pairing has one `ParentMessenger` -and `ChildMessenger` contract deployed to the *Hub and *Spoke networks respectively. - -Depending on the specific EVM networks that the *Hub and *Spoke contracts are deployed to, the implementations of the -Messenger contracts will differ. For example, sending messages between Mainnet and Arbitrum requires calling different -system contract interfaces than sending messages between Mainnet and Polygon does. This is why each network has its own -Messenger contract implementation in the `/chain-adapters` folder. - -# Technical Specification -To accomplish this upgrade, the following actions need to be taken: -- The `OracleHub` will need to be registered with the `Registry` so that it can make requests to the DVM.

The token is a synthetic index based on the recent trading prices of CryptoPunks. The previous price identifier ```PUNKETH-1221``` found in [UMIP 130](./umip-130.md) is not being re-used due to the fact that it was built for the EMP contract. This UMIP re-uses the logic of the previous ```PUNKETH``` price identifier from [UMIP 84](./umip-84.md) and uses the expiry timestamp per contract deployment to allow the creation of multiple overlapping uPUNK contracts. The ```PUNKETH_TWAP``` price identifier is ignored as the LSP is un-liquidatable and this logic is not necessary. - -The DVM should support requests for a price that resolves to the median most recent purchase price (in ETH) of each unique CryptoPunk traded in the last `T` seconds, as specified in the contract's ancillary data. - -# Motivation - -There are currently few synthetic non-fungible token (NFT) indexes available in the DeFi space.

This originality has lead to them being highly valued and having consistent enough trade volume. -* _Median Price_: The median price allows for the index to reflect common trading prices across many CryptoPunks rather than to respond to particular transactions. The default median timeframe is 30 days, and may be changed per LSP contract using ancillary data. -* _Unique CryptoPunks_: We only use the most recent trade price for each CryptoPunk. This is a security feature since if we used each transaction then a single person could trade one CryptoPunk amongst accounts they owned to manipulate the price. -* _Median rather than the mean_: Calculating the mean incorporates the price of every single transaction which means that someone who owned a single CryptoPunk could have a small effect on the price. The median can still be manipulated but, given the uniqueness restriction above, it would require someone to own enough CryptoPunks to make up half of the monthly transactions. - - -# Implementation - -When a price request is made, the following process should be followed: - -1. Determine the timeframe `T` used to calculate the price from Ancillary Data. See the *Ancillary Data Specifications* section for more infomation on retrieving this data. -2. Retrieve all CryptoPunk `PunkBought` events from `T` seconds prior to expiration -3. Identify the last price that each CryptoPunk was traded at using the event data -- Only one price should be produced per CryptoPunk even if they had traded multiple times. Due to a [bug in the CryptoPunk Market](https://github.com/UMAprotocol/UMIPs/pull/261#discussion_r622282931), this isn't as straightforward as reading the most recent value from the `PunkBought` event. The process we use is: - - Scan through all of the `PunkBought` events and identify the function call that generated the `PunkBought` event: - - If it was generated by `buyPunk` then use the `PunkBought.value` price - - If it was generated by `acceptBidForPunk` then we load all of the `PunkBidEntered` for that particular CryptoPunk and use the most recent bid (only one bid can be outstanding at a time and is always the highest) - - In both cases, we ignore any trades that are registered with a price of 0 and look back to the most recent non-zero price. -4. Take the median of these prices - If there is an even number of prices, take the mean of the two values closest to the median. - - - -**Example** - -If `T` from ancillary data is `2592000` and the timestamp requested was `1619222400` then: - -* We would need to identify all `PunkBought` events from `1619222400 - 2592000 -> 1616630400` to `1619222400` -* Imagine that we had 5 `PunkBought` events with (`ts`, `punk_id`, `eth`) pairs of `[(1616630450, 1000, 20), (1616631450, 5000, 30), (1616631550, 5000, 35), (1618631550, 6000, 22), (1618632550, 9999, 15)]`. -* We would need to check what function generated each `PunkBought` event. Suppose they were all generated by `buyPunk`, then the prices we would use to compute the median would be `[20, 35, 22, 15]` -* There are an even number of values, so there's no "median value" in the data -- Thus we find the number between the two values closest to the median `[20, 22]` to get a price of `21` - - - -# Security Considerations - -One of the main concerns is that someone with sufficient CryptoPunks chooses to manipulate the price. - -For example, there are accounts that own about 400 unique CryptoPunks and the unique number of CryptoPunks that traded in the last 30 days is about 600. An individual who owns 400 CryptoPunks and traded them amongst their own accounts at prices near zero could corrupt the price by driving it to zero after having minted and sold the tokens at a high price. - -One benefit to using an oracle with human intervention is that voters could recognize this type of price manipulation and there are other viable proxies for the expected price of a CryptoPunk.

The timeframe of this median value will depend on the value in the ancillary data field of the contract. - -The DVM should support requests for a price that resolves to the median monthly Ethereum gas price as specified in the implementation section, without needing the additional logic of previous UMIPs that contain EMP-specific AMM TWAP liquidation procedures. - - -# MOTIVATION -This UMIP updates the existing motiviations for uGAS as described in [umip-16](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-16.md) and [umip-20](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-20.md). The motivation from [umip-22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md) is no longer needed as there is no liquidation process for LSP contracts. - -From UMIP-16: - -> Cost: Calculating an aggregatory statistic of gas prices on a confirmed block or range of blocks on the Ethereum blockchain is easy by virtue of the fact that all needed data is readily available on any Ethereum full node, whether run locally or accessed remotely through well-known providers such as Infura or Alchemy. Additionally, this data can be accessed through querying publicly accessible Ethereum blockchain data sets. -> -> Opportunity: Gas options/futures can help users and developers hedge against gas volatility allowing them to budget their gas consumption efficiently. Providing a price feed for settlement is a prerequisite. - -From UMIP-20: -> For the creation of a tokenized gas price futures contract, it is desired that the DVM return the aggregatory gas price for 1 million units of gas. Using the gas price for a million units of gas is more suitable for a tokenized futures contract because tokens will actually represent a non-negligible amount of value. If a token was built with the identifiers defined in UMIP-16, participants would need to transact in millions/billions of tokens to capture any substantial value, as the price of each token would be somewhere in the range of 10-150 Gwei. - -# MARKETS & DATA SOURCES - -Information necessary to determine a price for this price identifier requres access to an ethereum full node, either run locally or accessed remotely through well-known providers such as Infura or Alchemy is.

(The above number shows a 30 day median.) In order to work with the previous calculations, this number should be rounded to the nearest previously approved median time period (in whole hours) as seen in the *Rationale* section. This number is to then be used to determine the minimum number of blocks used to calculate the median gas price over that time period as described in that section and the *implementation* section. - -When the above example ancillary data is stored as bytes, the result would be: `0x4e3a373230` - -if there is no ancillary data present, this value should default to `720` which is 30 Days. - -# RATIONALE - -From UMIP-16: - -> The volatility of gas prices on Ethereum is a well-recognized problem that is only made worse by the ever increasing network congestion in recent months. This creates an opportunity for options/futures underwriters to create financial products that help decentralized applications (dApps) and their users hedge against gas price variability and have a consistent risk-minimized experience. The UMA protocol is well-positioned to provide the necessary plumbing for such products to flourish. Such products will need to rely on the DVM as a settlement layer in case of disputes. Therefore, by supporting data feeds for gas prices, the DVM opens the door for a win-win-win situation between financial products, users/dAaps, and the Ethereum network at large. - -In the following quote, the wording is taken from UMIP-16 but the `gas_price` parameter was updated to `effective_gas_price` to account for EIP-1559 as described in [UMIP-129](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-129.md). - -> Each transaction included in an Ethereum block pays an amount of Ether per 1 unit of gas consumed. That amount is (a) specified by a `effective_gas_price` parameter attached to a transaction, (b) is expressed in the smallest unit of the Ether currency which is `Wei`, and is set by the transaction submitter as a bid offered to the miners to have the transaction included. We therefore have a set of `effective_gas_price`s per block. -> -> There are two important factors to consider: (1) there is a block each 12-15 seconds in the Ethereum blockchain, and spikes in gas prices are routinely observed, and (2) miners can easily manipulate gas prices in a given block (especially in absence of a fee burn). Therefore, an aggregatory statistic needs to be computed over a sufficiently long range of blocks to proof against abnormalities whether due to extreme volatility or miner manipulation. We propose the median gas price over 1 hour (1HR), 4 hours (4HR), 1 day (1D), one week (1W), and 1 month (1M) periods _weighted by_ the gas used in a transaction. For safety and to proof against price manipulation and/or possible abnormal delays in block production, the DVM requires that a minimum number of blocks must have been mined within a given period. Otherwise, the DVM medianizes over a preset number of blocks defined in the following table: - -Updated table clarifying median price durations to use for this UMIP. - - | Identifier | Number of Hours Contained (N) | Minimum number of mined blocks (B) | - |-------------|--------------|----------------------------------| - | GASETH-1HR | 1 | 200 | - | GASETH-4HR | 4 | 800 | - | GASETH-1D | 24 | 4800 | - | GASETH-7D | 168 | 33600 | - | GASETH-30D | 720 | 144000 | - -> For example, if the GASETH-1HR is requested for `t1` = October 1st 2020 UTC 00:00:00, and the number of blocks mined between `t0` = September 30th 2020 UTC 23:00:00 and `t1` is less than 200, then the DVM medianizes over the 200 blocks mined at time <= `t1` regardless of how long (in wall clock time) it took for these blocks to be mined. - -# IMPLEMENTATION -DVM voters should use the timestamp from the contract that is being voted on. This timestamp can either be queried from the `expirationTimestamp` field in the LSP contract or from the `timestamp` field in the data of the `requestPrice` price function when `expire` is called. The time period to medianize over should be determined from the `N` variable in ancillary data, which should be rounded per the *Ancillary Data Specification*. - -**The rest of this section is replicated from the *Implementation section* in [UMIP-129](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-129.md). ** - -In order to account for the changes to the fee market included in EIP-1559, the following pseudo-algorithm is used to calculate the exact data point to report by a DVM reporter: - -```python -def return_median(t, N) - assert N in [1, 4, 24, 168, 720] - minimum_ranges = {1: 200, 4: 800, 24: 4800, 168: 33600, 720: 144000} # a mapping between the durations 1HR, 4HR, 24HR (1D), 168HR (1W), 720HR(1M) and the corresponding mimimum number of blocks that must have been mined within the period. - - # `t` is number of seconds since the epoch (unix time) - end_block = block.at(timestamp=t) # rounded down - offset = 3600*N # there are 3600 seconds/hour - start_block = block.at(timestamp=(t-offset)) - - # the DVM imposes a minimum number of blocks within a given time period to ensure safety against price manipulation - if end_block-start_block < minimum_ranges[N]: - start_block = end_block - minimum_ranges[N] - - total_gas, rolling_sum = 0, 0 - TXes = [] - - # loop over the block in the defined range starting with the least recent - for b in range(start_block, end_block, 1): - # gasUsed is in the header of each block - total_gas += b.gasUsed - for tx in b.transactions(): - gas_price = tx.effectiveGasPrice - gas_used = tx.totalGasUsed - TXes.append((gas_price, gas_used)) - - # sort transactions by gas_price ascendingly - sorted_TXes = sorted(TXes, key=lambda tup: tup[0]) - - for gas_price, gas_used in sorted_TXes: - rolling_sum += gas_used - if rolling_sum > total_gas/2: - return gas_price -``` - -An alternative method, for a DVM reporter to calculate this exact data point, would be to run the below SQL query against a public dataset of Ethereum node data such as Google BigQuery's `bigquery-public-data.crypto_ethereum.transactions` dataset. - -This query is parameterized with a UTC timestamp `t1`, a time range defined by the price identifier being used (i.e. 24HR) `N`, a lower bound of time `t2` defined by `t1 - N * 3600` and a minimum block amount `B` (explained in the *Rationale* section). - -```sql -DECLARE halfway int64; -DECLARE block_count int64; -DECLARE max_block int64; - --- Querying for the amount of blocks in the preset time range.

DVM reporters are free to develop additional implementations, as long as the implementations agree with the computation methodology defined in the *Rationale* section and specifications of the *Technical Specifications* section. - -# Security considerations - -From UMIP-16 - ->Anyone relying on this data point should take note of the fact that manipulating the gas prices in a **specific** block or a short range of blocks is achievable by miners whether to inflate or deflate them for their own self-interest or on behalf of an attacker that bribed them to do so. The longer the range the requested statistic covers, the less the risk of manipulation is. This risk will also be significantly inhibited once [fee burn](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1559.md) is introduced in the Ethereum blockchain, because stuffing/padding blocks will have a non-zero cost even to miners (PoW) or block-producers (PoS). -> ->A large enough number of UMA governers should be running their full node to ensure data integrity. Relying on third-party full nodes presents a risk of manipulation of data, however if at least **one** governer is relying on their own full node, such manipulation is easily detectable.

This upgrade will enforce that DVM balance snapshots are captured from EOA wallets to prevent the use of flash-loans in this context. This upgrade will also change the rewards expiry timeout from 2 weeks to 1000 years, which effectively amounts to no expiration. - -## Motivation & Rationale - -The UMA voting mechanism uses a commit-reveal scheme, where votes are weighted in proportion to the token balance of the voters. The corresponding snapshot of the token distribution is taken at the start of each reveal phase, either through a dedicated function call, or automatically alongside the first revealed vote. - -However, it is possible for users to take out a flash loan of UMA tokens from a decentralized exchange, trigger the snapshot and then repay the loan in a single transaction. This would arguably give them undue influence over the result of the vote. Given the current state of the DeFi ecosystem, the flash-loan scenario is significantly simpler, more plausible, and arguably more concerning, so it warrants a dedicated mitigation. - -This UMIP proposes a solution that makes it imposable to utilize flash loans during voting, thereby enforcing that users hold UMA tokens beyond a single block if they wish to participate in governance. - -This UMIP was originally motivated by an analysis conducted by the UMA engineering team that identified the issue in July 2020. The analysis can be found [here](https://docs.google.com/document/d/11ap5q2ga2OaVIV6MLxpRjzbLZTr0xraUIt2DdfcyzWI/edit?usp=sharing). There was also a detailed discussion in the OpenZepplin Community forum on the implementation details of this solution which can be found [here](https://forum.openzeppelin.com/t/erc20snapshot-and-flash-loans-swaps-mints/3094). - -While redeploying the new version of the contract, the parameters can be reconsidered. The community has expressed dissatisfaction with the 2-week reward expiration. While the voting contract is being modified, it seems prudent to effectively remove this expiration. - -## Technical Specification - -This UMIP addresses the flash-loan scenario by requiring the address that triggers the snapshot to provide an ECDSA signature over a known message, which guarantees that it is an externally owned account(EOA). For simplicity, the ability to automatically trigger a snapshot on the reveal has been removed, although the same effect can be achieved with multiple function calls. - -The implications of this are that the first revealer is required to submit two transactions: - -1. Call `snapshotCurrentRound` with an ECDSA signature which is used to capture the UMA token balances for the voting round. The inclusion of this signature ensures that only EOAs can preform the snapshot as an ECDSA signature can not be generated by a smart contract within a flash-loan. -2. Call `revealVote` to reveal their vote in the normal flash-loan. - -All subsequent voters can call `revealVote` as they would previously have done. - -As for the rewards expiration, voters will be able to wait as long as they like before retrieving their rewards. - -## Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/packages/core/contracts/oracle). The directory contains the [implementation](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/oracle/implementation/Voting.sol) of the `Voting` contract which preforms the key voting logic within the DVM and has the updated logic to include the ECDSA signature verification. - -The specific changes made in this UMIP can be seen in [this](https://github.com/UMAprotocol/protocol/pull/1767) pull request. - -The new Voting contract should have identical parameters to the pre-existing Voting contract, except that rewardsExpirationTimeout will be equal to `31536000000` (1000 years in seconds). - -## Security considerations - -These changes _have_ been audited by OpenZeppelin and the full audit report can be read [here](https://blog.openzeppelin.com/uma-audit-phase-3/). diff --git a/research/uma/umips/umip-150.md b/research/uma/umips/umip-150.md deleted file mode 100644 index 38e11995..00000000 --- a/research/uma/umips/umip-150.md +++ /dev/null @@ -1,39 +0,0 @@ -**UMIP-150** - -- **UMIP title:** Add UMA as collateral currency on Polygon -- **Author:** Geoff (stadnykgeoff1@gmail.com) -- **Status:** Approved -- **Created:** 15 February 2022 -- **Discourse Link:** https://discourse.umaproject.org/t/create-add-uma-as-collateral-currency-to-polygon-md/1408 - -## Summary (2-5 sentences) - -This UMIP proposes adding UMA on Polygon for use as collateral in UMA contracts. - -## Motivation - -The addition of this collateral currency offers additional functionality to the UMA protocol and increases the range of contracts that can be built. - -## Technical Specification - -To accomplish this upgrade, the following changes need to be made: - -- The UMA address https://polygonscan.com/token/0x3066818837c5e6ed6601bd5a91b0762877a6b731 needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 250 UMA needs to be added in the Store contract. -- A final fee for the UMA Mainnet address https://etherscan.io/token/0x04Fa0d235C4abf4BcF4787aF4CF447DE572eF828 needs to be updated from 90 to 250. - - -## Rationale - -This store fee was chosen as it is approximately equivalent to $1500 in line with other collateral currencies as determined by CoinGecko - -## Implementation - - -This change has no implementations other than the aforementioned governor transactions - -## Security considerations - -Adding a collateral currency introduces a level of risk into the UMA Ecosystem.

The approved PIP directory contains all necessary steps, software, and endpoints to validate an index. - -The index can be looked up and validated by participants of the DVM and/or disputers through the `timestamp` and `ancillaryData` passed into the Skinny Optimistic Oracle's `requestAndProposePriceFor` function. The `ancillaryData` consists of the methodology, time period, and target asset concatenated into a single parameter: `id:{METHODOLOGY}-{TIMEPERIOD}-{ASSET}`. This parameter can be deconstructed and used to access data sources. If `ancillaryData` does not comply with these standards, DVM participants should return the "magic number": `-3735928559`. The "magic number" should also be returned for instances where the `ancillaryData` is formatted correctly but where the methdology, time period, and/or targetAsset are not defined/whitelisted within the Volatility DAO's PIP approved repository. We understand that this is a non-traditional format for `ancillaryData` but it is necessary to optimize storage within The DAOracle smart contracts. - -For an example of how to use the `ancillaryData` to recreate an index please see Implementation below. - -Redundancies for accessing data - -Each PIP contains information on how to access raw data. In general there are two ways of doing this: - -1. Most indices will post to IPFS and their data snapshot can be queried through two different URLs: -* One based on methodology, time period, asset, and timestamp. -* One based on the IPFS hash. -2. In cases where the IPFS data is completely lost or broken, the PIP directory of the methodology will outline alternate ways of accessing the data in the README.md (e.g. it may list the exchanges or other third-party data provider from which the data originated and any special processing needed for aggregating the feed(s) for input to the open-source implementation). - -As part of the PIP process The Volatility DAO sets a parameter called `dataPeriod`. This represents the time period at which snapshots of input data & index values are saved to IPFS (or another open immutable database). `dataPeriod` can be set to any time resolution (e.g. 1 second or 1 hour) but should never be greater than the desired amount of time between audits. Only recent snapshots can be relayed to The Volatility Oracle. DVM participants should also deny submissions of "old data." DVM participants can use the following logic to determine if data is considered old: - -``` -submissionBlockTime = the UTC time of the tx to the Skinny OO -timestamp = the UTC timestamp of the snapshot data -disputePeriod = the amount of time where a user can dispute a value within the Volatility Oracle - -Data is old if the following is TRUE: - -submissionBlockTime > timestamp + disputePeriod - -``` - - - -## Rationale -Rationale For the Volatility DAOracle: - -Getting frequent index results on-chain through the Optimistic Oracle is not tenable because of the Tragedy of the Commons. It is not in an individual user’s best interest to pay gas to create a frequent audit trail (e.g. economically it makes sense for an individual user to requestPrice infrequently). The Volatility DAOracle solves this by building a new layer of incentives on top of the Optimistic Oracle. - - -Rationale For This Specific Implementation: - -Having all Volatility DAO indices and benchmarks under one UMIP is important because each individual methodology can be applied across different time periods and assets. For example, with the initial Model Free Implied Volatility methodology (MFIV) an index could be created for ETH or BTC for time periods ranging from roughly 1-364 days. This means that the single methodology could create roughly 728 indices. It would not make sense to create 728 different UMIPs, one for each index. Instead, we feel the best method is to have a single UMIP that defines an overarching framework for cataloging and querying each Volatility DAO index, its implementation, raw data, and methodology. - - -## Implementation -Using the `timestamp` and `ancillaryData` from a `requestAndProposePriceFor` for this UMIP you can query all necessary tools to recreate any index within the Volatility DAOracle. The `timestamp` is seconds since the Unix epoch. The `ancillaryData` consists of three data points concatenated into a single parameter: `id:{METHODOLOGY}-{TIMEPERIOD}-{ASSET}`. - -* `METHODOLOGY` - This is the identifier for the methodology. This four-character identifier can be used to look up the methodology in the [Volatility DAO Github](https://github.com/Volatility-DAO/PIPS/tree/main/Approved/Volatility_Oracle_PIPs). -* `TIMEPERIOD` - This is the time period to which the methodology is applied. Time period uses standardized time formats, where lower-denomination units are lowercase and higher-denominations are uppercase: - * `s` = seconds - * `m` = minutes - * `h` = hours - * `D` = Days - * `W` = Weeks - * `M` = Months - * `Y` = Year - * For example, 14D means 14 Day volatility. -* `ASSET` - This is the asset of which volatility is measured. For example, ETH means Ethereum and BTC means Bitcoin. - * Note: Each methodology that is approved within the Volatility DAO PIP repository has an Index_PIPs directory. That directory contains all of the parameters for the indices of the methodology as MD files. The naming convention of the MD file is the same as the `ancillaryData`. These files whitelist the `targetAsset`to remove the possibility of collision. - -The following example demonstrates how this system works: -1. Use `ancillaryData` and `timeStamp` from `requestAndProposePriceFor`: - * ancillaryData: `id:MFIV-14D-ETH` - * timeStamp: `1643288400` -2. Use the `timestamp` and `ancillaryData` to look up the following: - * MFIV matches the methodology directory [here](https://github.com/Volatility-DAO/PIPS/tree/main/Approved/Volatility_Oracle_PIPs). This is where you get the open-source code to validate the index. The README.md of the methodology directory will have clear instructions on how to validate an index. - * Within the methodology directory is an Index_Pips directory. This must contain an md file named the same as the 'ancillaryData' (i.e. MFIV-14D-ETH.md). - * `timestamp / TIMEPERIOD / ASSET` are all used to query the IPFS data of the calculations. Instructions for doing this are required within the README of every PIP. You can see the MFIV README [here](https://github.com/Volatility-DAO/PIPS/blob/main/Approved/Volatility_Oracle_PIPs/MFIV/README.md). - * NOTE: `timestamp` is the timestamp of the post of data to IPFS. This IPFS data file includes the input and output data for an index. An index can only be queried as often as this data is posted to IPFS. - * NOTE: The Volatility Oracle or other requestor should send the `timestamp` used to query the IPFS file. If this `timestamp` does not allow for a query, then DVM participants should return the "magic number" (described above). - - -## Security considerations -There are several potential security considerations. Each of these has been mitigated as much as possible: - -* **Data** - To create an index on the DAOracle a creator needs to provide the input data on IPFS. The infrastructure that they use to do this could be a vector of attack or could simply break. As a redundancy, the creator must also describe how to access and filter raw data. In many cases the raw data could also be a vector of an attack. The methodology should try to address this if possible. However, it may not be possible to mitigate attacks on raw data (e.g. a price series from an exchange). - -* **Volatility DAO** - * GitHub - The Volatility DAO GitHub could be a vector of attack. For example, if someone were to gain access who should not have access. Every DAO member who has access to the repo uses basic security features like 2FA and signed commits. - * 51% attack - 51% of VOL tokens could be acquired by someone to change how an index calculates. This is mitigated by the process in which indices are approved. All indices must use open-source software and must go through a period of public review. Inserting malicious code would be possible if someone owned 51% of tokens, but users would know that the code is malicious and could avoid using it. Furthermore, the UMA community could be notified at that point and time and could take action to invalidate this UMIP. - diff --git a/research/uma/umips/umip-152.md b/research/uma/umips/umip-152.md deleted file mode 100644 index 0d16bf21..00000000 --- a/research/uma/umips/umip-152.md +++ /dev/null @@ -1,284 +0,0 @@ -## Headers -- UMIP-152 -- UMIP title: Add ZODIAC as a supported price identifier -- Author: John Shutt (john@umaproject.org) -- Status: Approved -- Created: March 7, 2022 - -## Summary (2-5 sentences) -The ZODIAC identifier is intended to be used with an [Optimistic Governor](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/zodiac/OptimisticGovernor.sol) [Zodiac module](https://gnosis.github.io/zodiac/docs/intro) that allows you to control a [Gnosis Safe](https://gnosis-safe.io/) according to a set of rules defined off-chain and enforced with UMA's [Optimistic Oracle](https://umaproject.org/optimistic-oracle.html). Any address can propose transactions that follow the rules and any address can dispute a proposal to UMA's Optimistic Oracle within a challenge window. - -## Motivation -The ZODIAC identifier, coupled with the Optimistic Governor module, will allow for a new era of flexible "optimistic governance," where management of DAO treasuries and other multi-signature wallets can be managed more effectively, without being limited to X-of-Y signing schemes or tokenholder votes, although the Optimistic Governor module can enforce those things, too. - -To date, DAO governance has twisted itself to conform to the limitations of simplistic tools, instead of finding the best rules to coordinate around shared resources. The ZODIAC identifier allows a DAO to publish their rules in plain language with sufficient detail for a neutral third-party observer to determine whether transactions submitted to a Gnosis Safe follow the rules or not, and then have any address propose and execute transactions that follow those rules. - -Because human voters can be brought in the loop to resolve disputes, this is an incredibly flexible and powerful form of DAO governance. Due to that flexibility, users of this identifier should be sure to make their rules as clear as possible, including the process for upgrading to a new set of rules. - -## Technical Specification -The Optimistic Governor module is a new tool and can be paired with an administrative multi-signature scheme for emergency actions for greater user assurance. Over time, the signature threshold can be increased for the emergency multi-sig, and eventually the multi-sig can be eliminated entirely, with all governance actions going through the Optimistic Governor. - -Each Gnosis Safe will have its own Optimistic Governor module contract which will store a hash of transactions proposed by external addresses. Each proposal hash represents a bundle of transactions and each proposal emits an event with the full transaction details. - -``` - -event TransactionsProposed( - address indexed proposer, - uint256 indexed proposalTime, - Proposal proposal, - bytes explanation, - uint256 challengeWindowEnds -); - -struct Transaction { - address to; - Enum.Operation operation; - uint256 value; - bytes data; -} - -struct Proposal { - Transaction[] transactions; - uint256 requestTime; -} -``` - -The module contract stores a mapping of proposal hashes to their proposal time, to verify proposals during execution and to prevent duplicate proposals. The contract also stores a string reference to an off-chain set of rules that have been publicly published, which may be an IPFS hash, a URI, or something else. - -Other important configuration variables stored by the contract are the collateral token address (for bonds), the amount of collateral tokens proposers and disputers are required to post as a bond, the liveness period for disputes, the identifier used by the module, and the address of the Optimistic Oracle and the Finder. - -``` -// This maps proposal hashes to the proposal timestamps. -mapping(bytes32 => uint256) public proposalHashes; - -// Since finder is set during setUp, you will need to deploy a new Optimistic Governor module if this address need to be changed in the future. -FinderInterface public immutable finder; - -IERC20 public collateral; -uint64 public liveness; -// Extra bond in addition to the final fee for the collateral type. -uint256 public bondAmount; -string public rules; -// This will usually be "ZODIAC" but a deployer may want to create a more specific identifier. -bytes32 public identifier; -OptimisticOracleInterface public optimisticOracle; -``` - -When a user creates a proposal, they submit an array of transactions along with an optional explanation that explains the intent and purpose of the transactions, which is useful for voters trying to understand the transactions and whether or not they follow the published rules. - -``` -function proposeTransactions(Transaction[] memory transactions, bytes memory explanation) public { - ... -} -``` - -In this function, a price request and price proposal are submitted to the Optimistic Oracle, and the proposal hash is generated and stored in a mapping to the proposal time. - -``` -// Create the proposal hash. -bytes32 proposalHash = keccak256(abi.encode(_transactions)); - -// Add the proposal hash to ancillary data. -bytes memory ancillaryData = AncillaryData.appendKeyValueBytes32("", "proposalHash", proposalHash); - -// Check that the proposal is not already mapped to a proposal time, i.e., is not a duplicate. -require(proposalHashes[proposalHash] == 0, "Duplicate proposals are not allowed"); - -// Map the proposal hash to the current time. -proposalHashes[proposalHash] = time; - -// Propose a set of transactions to the OO.

Without a flexible, natural language based system for outlining rules of operation, and a trustless and decentralized mechanism for enforcing those rules, DAOs can only exist in a stunted form, like an oak tree growing in a pot with no space for deep roots. - -This UMIP and the associated module code brings the flexibility of law to smart contracts, with UMA voters serving as judge and jury in case of disputes. Unlike the tradition of common law, however, UMA voters do not attempt to create precedent for ambiguous cases, resolve controversy, or fill in the gaps. If there is ambiguity about whether a particular proposal follows the rules, it is simply rejected. - -The onus is on the DAO to write clear rules and on the proposer to ensure their transactions follow the rules, with no room for ambiguity by a neutral third-party observer. - -This methodology allows for a huge amount of flexibility for DAOs to manage their shared resources without requiring UMA voters to make subjective judgements, which would be difficult for voters and could potentially create unpredictable and undesirable results for DAOs. - -## Implementation -Voters should read the plain language rules referenced in the public `rules` value in the Optimistic Governor contract that requested a price and check the proposed transactions against those rules. - -This `rules` value will usually be an IPFS hash. If it is, voters can view the rules through a web browser by going to https://ipfs.io/ipfs/ or by using any other system to access the document using IPFS. If the `rules` value is a web URI, voters can simply enter the web URI into any web browser. - -The system is quite flexible, so voters may need to find other publicly verifiable data to determine if the proposed transactions follow the rules. For instance, they may need to check the result of a Snapshot vote to verify that a governance proposal was approved by the DAO token holders, or check the current price of a token to verify a proposal to make a trade according to a trading strategy outlined in the rules, or confirm public misbehavior by some address to verify a proposal to slash a bond posted by that address. - -If the proposer included an optional `explanation` in the ancillary data of the price request, that may be helpful for understanding the intent of the proposal, but voters should primarily consider the actual effects of the proposed transactions and verify that the transactions clearly and unambiguously follow the rules. - -If a proposal is disputed, the disputer is encouraged to publish their reasoning in a public forum to assist UMA voters in their determination of whether or not the proposal was valid. - -Voters should consider four sources of public information in their ruling: - -1. The published rules for the Optimistic Governor module. -2. The rationale given by the proposer in explanation (if any). -3. The arguments presented by disputers. -4. The voter's understanding of what the transactions *actually* do, regardless of the stated rationale. - -If a proposal follows the rules, an UMA voter should return a value of `1`. - -If a proposal doesn't follow the rules, an UMA voter should return a value of `0`. - -If a voter is unsure if a proposal follows the rules, an UMA voter should return a value of `0`. - -If the rules are unclear or malformed, an UMA voter should return a value of `0`. - -It is the responsibility of the DAO users of the `ZODIAC` identifier to write clear and unambiguous rules. If their rules are unclear, they should expect proposals that get disputed to be rejected by UMA's oracle. - -It is important that the process for changing the rules be particularly clear and unambiguous, if a rule change process is allowed by the DAO. This allows the DAO to add, remove, or clarify rules as needed, analogous to a constitutional amendment. - -The implementation of the Optimistic Governor module can be [found here](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/zodiac/OptimisticGovernor.sol). - -The requester will be the Optimistic Governor contract itself, which means voters can use the requester address to find the contract on Etherscan and inspect the public `rules` value. - -### Example Rules -The `ZODIAC` identifier is designed to allow rules to be as flexible as possible while still being clear to UMA voters called in to resolve disputes. These examples are meant to inspire creativity in users creating their own rules and demonstrate the legalistic approach they should take. - -The actual rules for a given module will depend entirely on the intended use of the Gnosis Safe governed by that module and the community dynamics of the DAO in charge. - -As a reminder, these rules should be published publicly and referenced in a string stored in the module contract, as an IPFS hash, a website URI, or some other format. - -``` -EXAMPLE RULES - -ABC DAO was formed to bring our token holders to the moon, Mars, and beyond. - -To that end, we have established the following rules governing our treasury, contained in the Gnosis Safe at Ethereum address 0xbcd...234. This Gnosis Safe also has the ability to change certain parameters in our other smart contracts. - -1. Transactions proposed by 0xabc...123 are valid unless they violate other rules. This address is a multi-signature wallet controlled by the core development team. - -2. No more than 10% of the value contained in the Gnosis Safe at address 0xbcd...234, which is governed by the Zodiac module 0xcde...345, may be transferred out of the Gnosis Safe during a single 24-hour period. - -3. Proposals including transactions that call functions on the smart contract 0xdef...456 must be approved by a Snapshot vote backed by more than 50% of the total supply of $ABC ERC-20 tokens and must be proposed by 0xabc...123. - -4. Proposals that have been approved by a Snapshot vote backed by more than 50% of the total supply of $ABC ERC-20 tokens are valid. - -5. Transactions proposed by an address owned by Elon Musk are valid unless they violate other rules. Elon Musk can prove ownership of an address through a post on the @elonmusk Twitter account combined with a public press release. - -6. These rules may be changed at any time by a transaction approved by a Snapshot vote backed by more than 50% of the token supply of $ABC ERC-20 tokens, or by Elon Musk. - -7. Elon Musk may not propose transactions when it is the second Tuesday of the month, Pacific Time Zone. -``` - -### Successful Execution Flow -1. DAO member Alice has a great idea for utilizing the DAO treasury and writes some Ethereum transactions that would execute her idea. -2. Alice holds a Snapshot vote to approve their idea and associated transactions. -3. The majority of $ABC tokens back Alice's proposal in the Snapshot vote. -4. Alice submits the proposal to the Zodiac module governing the Gnosis Safe and notes in the explanation that the proposal was approved on Snapshot and includes a link to the Snapshot results. Alice includes a bond with her proposal. -5. The proposal is not disputed within the challenge window and can be executed by any address. -6. Bob, another member of the DAO, executes Alice's proposal since Alice is out watching a movie. -7. Alice's transactions are executed and the treasury funds are spent according to her plan, which was approved by a Snapshot vote. - -### Disputed Execution Flow -Starting after step 4 from the Successful Execution Flow: - -1. Bob, who is jealous of Alice's popularity in the DAO, disputes her proposal even though it has been approved by a Snapshot vote. Bob includes a bond with his dispute and rages against the proposal on Twitter. -2. The dispute is escalated to UMA's data verification mechanism where UMA tokenholders analyze the proposal, the arguments from Alice and Bob, and the rules published by the DAO and referenced in the Zodiac module. -3. After reading the rules, the vast majority of UMA token holders conclude that the proposal followed the rules and should be executed, and commit a value of `1` during the commit period. -4. UMA token holders reveal their votes during the reveal period. -5. After the reveal period, the settlement value is `1`. The Zodiac module receives the settlement value and allows any user to execute the proposal. -6. Bob loses his bond and Alice gets her bond back and a portion of Bob's bond. -7. Alice, vindicated, executes her proposal. - -### Blocked Execution Flow -1. Elon Musk proposes to spend some DAO treasury funds, and includes a bond with his proposal, but it is the second Tuesday of the month, Pacific Time Zone. -2. Alice disputes Elon's proposal and includes a bond with her dispute. -3. The dispute is escalated to UMA's data verification mechanism where UMA tokenholders analyze the proposal and the rules published by the DAO and referenced in the Zodiac module. -4. After reading the rules, the vast majority of UMA token holders conclude that the proposal did NOT follow the rules and should not be executed, and commit a value of `0` during the commit period. -5. UMA token holders reveal their votes during the reveal period. -6. After the reveal period, the settlement value is `0`. The Zodiac module receives the settlement value and deletes the invalid proposal. -7. Elon loses his bond and Alice receives her bond back and a portion of Elon's bond. - -### Emergency Administrative Action -1. The DAO includes an emergency multi-sig that can override any proposal. -2. DAO member Alice has a great idea to steal all of the money in the treasury for herself and writes some Ethereum transactions that would execute her idea. -3. Alice holds a Snapshot vote during a holiday when people aren't paying attention and bribes enough voters to get majority approval. -4. Alice submits the proposal to the Zodiac module governing the Gnosis Safe and notes in the explanation that the proposal was approved on Snapshot and includes a link to the Snapshot results. Alice includes a bond with her proposal. -5. The signers on the emergency multi-sig are alerted in time and delete Alice's proposal. -6. The DAO votes on new rules that would prevent incidents like this in the future. - -## Security considerations - -### Ambiguity -Ambiguous or incomplete rules could put contracts using the `ZODIAC` identifier at risk of loss of funds. The rule that UMA voters should reject proposals that they are not certain follow the rules should help mitigate this. - -### Complexity -Complex bundles of transactions may be difficult for a layperson voter to analyze, leading to reliance on statements made by experts in support of or against a proposal. The rule that UMA voters should reject proposals they are not certain about means that complex proposals that actually do follow the rules may be blocked for some time. - -The DAO can resolve this issue by having alternative and less ambiguous mechanisms for expressing approval of complex proposals. For instance, the DAO's rules may state that a proposal whose transactions received XX% approval through a Snapshot vote, or were signed off on by 3 of 4 experts, should be approved. - -This allows the DAO to establish straightforward rules for simple, routine, or non-controversial transactions that can be proposed by any address and understood by any neutral third party, like an UMA voter. This is much more efficient than putting those transactions through, for instance, a governance vote every time. - -Complex proposals can be put through a more intensive process, like a Snapshot vote, that has an output that will be easy for a neutral third party to understand. - -### Short Challenge Windows -If the rules set by a DAO are complex, or the funds in a Gnosis Safe are substantial, a short challenge window may be a security risk. They may wish to have full flexibility of an off-chain set of rules enforced by the Optimistic Oracle but also set guardrails on what transactions can be triggered according to certain criteria. - -As an example, the DAO's rules may set limits on how much can be transferred out of a Gnosis Safe within a given window. Proposals that would result in greater than 5% of a Gnosis Safe's assets being transferred externally may require a 50% vote on Snapshot by tokenholders. - -The rules may also add additional requirements for special transactions, like changing parameters in a smart contract system controlled by the Gnosis Safe. Those transactions may need to be proposed by a core team member and/or signed off by X-of-Y members of an expert committee. This allows experts and selected DAO members to check important transactions without fully trusting them (after all, they can be off-boarded by tokenholders through a change in the rules). - -The reason to add these extra requirements for complex or potentially risky transactions is to make it easy for oracle observers to evaluate proposals within a short challenge window and dispute proposals that are obviously invalid. - -The more important a transaction is, the more requirements the DAO may want to put into their rules around that transaction. That makes it more likely that a disputer will step in to block bad proposals with confidence that they will be backed up by UMA voters since some unambiguous requirement was not fulfilled. - -### Continued Use of an Emergency Administrative Multi-Sig -In the long run, it should be possible to replace multi-sig control of a Gnosis Safe, with all governance actions going through the Optimistic Governor. While the Optimistic Governor is being implemented, however, and best practices around DAO rules are being established, it may be useful to retain a multi-sig as an emergency override mechanism. - -This multi-sig can protect against failures caused by unclear or inadequate rules or by some issue with the Optimistic Governor itself. However, it is important to remember that the continued existence of an emergency multi-sig adds additional trust assumptions, and it is possible for rogue multi-sig signers to override actions that were approved through the DAO's stated governance system or the will of the DAO expressed through a SafeSnap vote. - -Over time, the signing threshold for the emergency multi-sig can be increased to make it harder for the multi-sig to overrule the normal function of the Optimistic Governor, and eventually the multi-sig administrative powers can be dropped entirely. - -### Poorly Formed Proposals -It is possible that transactions in a proposal may not match the intent of the proposer and may not be well understood by potential disputers. As a result, bad transactions may go through and result in loss of funds or accidents in smart contracts controlled by a Gnosis Safe. - -This can be prevented by adding extra checks for complex proposals. Some examples are given in the "Short Challenge Windows" section above. - -It may be worthwhile to add extra checks even for theoretically simple proposals, since mistakes can happen in simple proposals, too.

Once the Polygon block containing the transaction that emitted this event is included on Ethereum, it can be relayed to its target on Ethereum. In order to relay it, a proof must be constructed off-chain that alleges that the `MessageSent` event was included in a block that was checkpointed to Ethereum. The logic that validates this proof is contained in the `OracleRootTunnel` contract, and specifically in the base `FxBaseRootTunnel` contract. This proof-validation logic needs to be upgraded to handle proofs constructed on type 2 transactions. - -## Technical Specification -To accomplish this upgrade, the following actions need to be taken: -- The newly deployed `OracleRootTunnel` on Ethereum will need to be registered with the `Registry` so that it can make requests to the DVM. -- The newly deployed `OracleChildTunnel` will need to be set as the "Oracle" in hex (i.e. `0x4f7261636c65`) in the Polygon `Finder`.

A deposit is a cross-chain transfer request from an "origin" chain to a different "destination" chain, which is fulfilled when a "relayer" sends the depositor their desired transfer amount (less fees) on their desired destination chain. - -Relayers lend capital to the Across V2 system by fulfilling users' deposits via the spokes and are eventually repaid by the LP pool. "Bundles" containing many of these repayments are validated together by the [Optimistic Oracle ("OO")](https://docs.umaproject.org/protocol-overview/how-does-umas-oracle-work). In addition to validating individual repayment instructions, the OO also validates rebalance instructions that tell the LP pool how to transfer funds to and from the spoke pools in order to execute the repayments and pull deposited funds from the spoke to the LP pool. - - -If there is no relayer who can provide all the capital for a given deposit request, a "slow relay" (or "slow fill") is performed where the funds are sent from the -LP pool to the destination spoke to fulfill the deposit. These slow fill requests are also included in the aforementioned bundles. - -Bundles are implemented on-chain as [Merkle Roots](https://www.youtube.com/watch?v=JXn4GqyS7Gg) which uniquely identify the set of all repayments and rebalance instructions over a specific block range. Therefore, Across V2 moves capital to repay relayers and fulfil bridge requests through periodic bundles, all validated by the OO. - -This UMIP explains exactly how to construct and verify a bundle. - -![](./images/across-architecture.png?raw=true "Across V2 Architecture") - -# Motivation - -The ACROSS-V2 price identifier is intended to be used by the Across v2 contracts to verify whether a bundle of bridge-related -transactions submitted to mainnet is valid. - - -# Data Specifications and Implementation - -Note 1: the following details will often refer to the [Across V2](https://github.com/across-protocol/contracts-v2) repo -at commit hash: a8ab11fef3d15604c46bba6439291432db17e745.

See the section on [comparing events](#comparing-events-chronologically) for more details. - -Note 3: wherever unspecified, sorting should be ascending by default, not descending. - -Note 4: all event data should be identically returned by at least two independent, reputable RPC providers to give confidence in the integrity of the data. - -# Definitions - -## Comparing events chronologically -Smart contract transactions can emit events that conform to the specifications described in the "Returns" section of these [docs](https://web3js.readthedocs.io/en/v1.2.11/web3-eth-contract.html#contract-events). Specifically, an event is expected to have a unique combination of `blockNumber`, `transactionIndex` and `logIndex`. To compare events `e1` and `e2` chronologically, we can say -that `e1` is "earlier" than `e2` if `e1.blockNumber < e2.blockNumber` OR if `e1.blockNumber == e2.blockNumber && e1.transactionIndex < e2.transactionIndex` OR if `e1.blockNumber == e2.blockNumber && e1.transactionIndex == e2.transactionIndex && e1.logIndex < e2.logIndex`. - -So, "earlier" events have a lower block number, transaction index, or log index, and we should compare event properties in that order. - -## Valid bundle proposals -A root bundle can be proposed by calling `HubPool.proposeRootBundle()`, which will will emit a [`ProposedRootBundle`](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol#L148-L156) event. - -The root bundle is valid once *all* of its `PoolRebalanceLeaves` are executed via `HubPool.executeRootBundle()`, which can only be called after the proposed root bundle's `challengePeriodEndTimestamp` is passed. - -## Comparing deposit events chronologically for different origin chains -Each deposit emits a [`quoteTimestamp`](https://github.com/across-protocol/contracts-v2/blob/aac42df9192145b5f4dc17162ef229c66f401ebe/contracts/SpokePool.sol#L73) parameter. This timestamp should be evaluated within the context of the Ethereum network, and should be mapped to the Ethereum block who's [`timestamp`](https://ethereum.org/en/developers/docs/data-and-analytics/block-explorers/#blocks) is closest to the `deposit.quoteTimestamp` but not greater (i.e. `block.timestamp` closest to and `<= deposit.quoteTimestamp`). - -## Matching L1 tokens to Running Balances or Net Send Amounts -The [`RootBundleExecuted`](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol#L157-L166) event and [`PoolRebalanceLeaf`] structure both contain equal length arrays: `l1Tokens`, `netSendAmounts`, `bundleLpFees`, and `runningBalances`. Each `l1Token` value in `l1Tokens` is an address correspondingto an ERC20 token deployed on Ethereum Mainnet. It should be mapped to the value in any of the other three arrays (`netSendAmounts`, `bundleLpFees`, and `runningBalances`) that shares the same index within the array. - -For example, if `l1Tokens` is "[0x123,0x456,0x789]" and `netSendAmounts` is "[1,2,3]", then the "net send amount" for token with address "0x456" is equal to "2". - -## Versions -The `ConfigStore` stores a "VERSION" value in the `globalConfig`. This is used to protect relayers and dataworkers from using outdated code when interacting with Across. The "VERSION" should be mapped to an integer string that can only increase over time. The "VERSION" is updated by calling `updateGlobalConfig` so it is emitted as an on-chain event. The block time of the event that included the "VERSION" indicates when that "VERSION" became active. Relayers should support the version at the quote timestamp for a deposit, otherwise they risk sending an invalid fill. Proposers and Disputers should support the latest version for a bundle block range to validate or propose a new bundle. This version is independent from the version included in [speed up deposit signatures](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/SpokePool.sol#L668). - -# Ancillary Data Specifications - -The ancillary data only needs a single field: `ooRequester`, which should be the contract requesting the price from the -OO. Because that contract should contain enough information about the request for voters to resolve the validity of the -relay, no additional ancillary data is needed. - -Example: - -``` -ooRequester:0x69CA24D3084a2eea77E061E2D7aF9b76D107b4f6 -``` - -# Configuration Constants - -## Global Constants -The following constants should reflect what is stored in the [`AcrossConfigStore`](https://etherscan.io/address/0x3b03509645713718b78951126e0a6de6f10043f5#code) contract deployed on Etherscan. This contract is owned by Across governance and acts as the source of truth for the following variables. The global variables currently stored in the above contract for this UMIP are: -- "MAX_POOL_REBALANCE_LEAF_SIZE" -- "MAX_RELAYER_REPAYMENT_LEAF_SIZE" -- "VERSION" - - Across protocol version number. Supporting implementations should query this value against the value defined in their implementation to determine compatibility with the current protocol version. Failure to correctly evaluate the version number may mean that filled relays are not refunded from the HubPool, and may therefore result in loss of funds. For more information go [here](#versions). -- "DISABLED_CHAINS" - - This must be a stringified list of chain ID numbers. This cannot contain the chain ID "1", or the HubPool chain ID. Chains in here must be contained in `CHAIN_ID_INDICES`. -- "CHAIN_ID_INDICES" - - This should default to the value [1,10,137,288,42161] for any blocks older than the first time that this global variable was published. This is to account for the initial version of this UMIP which defined this ID list in the UMIP rather than in the ConfigStore contract. Chains can only be added to this list to be valid. - -To query the value for any of the above constants, the `AcrossConfigStore` contract's `globalConfig(bytes32)` function should be called with the hex value of the variable name. For example, the "MAX_POOL_REBALANCE_LEAF_SIZE" can be queried by calling `globalConfig(toHex("MAX_POOL_REBALANCE_LEAF_SIZE"))` which is equivalent to `globalConfig("0x4d41585f504f4f4c5f524542414c414e43455f4c4541465f53495a45")`. For example, this might return ->"25" - -## Token Constants -The following constants are also stored in the `AcrossConfigStore` contract but are specific to an Ethereum token address. Therefore, they are fetched by querying the config store's `tokenConfig(address)` function. -- "rateModel" - - This is a JSON struct of rate model parameters. - - These parameters should fully specify the rate model for this token as described in - [UMIP 136](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-136.md). - - Each field in this struct should be an integer represented as a string (to allow unlimited precision). - - The rateModel struct is only valid if it contains all of the following parameters: `UBar`, `R0`, `R1`, and `R2`. -- "routeRateModel" - - Similar to `rateModel`, this is a dictionary of `originChain-destinationChain` keys mapped to rate models that take precedence over the `rateModel` for a token on that specific deposit route. The route rate models should follow the same `UBar`, `R0`, `R1`, `R2` format as the default `rateModel` -- "spokeTargetBalances" - - This is contains a JSON mapping from chainId to JSON structs. - - Each struct contains two sub-fields, "target" and "threshold". - - Each is an integer represented as a string (to allow unlimited precision). - - These integers should both be positive values. If either is negative, it should be treated as "0" when used. - - The "target" integer should be < the "threshold" integer. If not, the "theshold" integer should be treated as if - it contained the same value as the "target" integer when used. - - If "spokeTargetBalances", a particular chainId is missing from the mapping, or "target" or "threshold" is missing, - the missing "target" and "threshold" should be defaulted to 0. - -For example, querying `tokenConfig("0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2")` might return: -> "{"rateModel":{"UBar":"750000000000000000","R0":"50000000000000000","R1":"0","R2":"600000000000000000"},"spokeTargetBalances":{"1":{"threshold":"200000000000000000000","target":"100000000000000000000"},"42161":{"threshold":"400000000000000000000","target":"200000000000000000000"}}}" - -_This UMIP will explain later how global and token-specific configuration settings are used._ - -# Preliminary Information - -The ooRequester address is expected to be an instance of the -[HubPool contract](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol). - -If any of the expected details in the ooRequester are not available in the expected form because the HubPool does not -match the expected interface, the identifier should return `0`. - -To get the proposal data, the voter should find events that match -[this signature](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol#L148-L156) -on the ooRequester.

If the timestamp matches the request timestamp, -then the [earlier event](#comparing-events-chronologically) is the one to be -used. If the timestamp is earlier than the request timestamp, the [later event](#comparing-events-chronologically) should be used. - -# Proposal Information - -From the selected event, one should be able to glean the following information: -- `bundleEvaluationBlockNumbers` -- `poolRebalanceRoot` -- `relayerRefundRoot` -- `slowRelayRoot` - -## Determining block range for root bundle proposal -The `bundleEvaluationBlockNumbers` is an ordered array of end block numbers for each destination chain for this bundle.

In the case where the `latest` block height hasn't advanced beyond the previous `bundleEvaluationBlockNumber`, then the block range for the proposal will go from the preceding proposal's `bundleEvaluationBlockNumbers` to the same number, i.e. block ranges of 0. - -Note also that the above rules for determining an end block don't apply if the chain ID is in the "DISABLED_CHAINS" list. if a chain exists in DISABLED_CHAINS, the proposed bundle must reuse the bundle end block from the last valid proposal before it was added.

If a match is found, the `destinationToken` should match the `destinationToken` - value in the `FilledRelay` event. If they don't match or if no matching event is found, the relay is invalid. - -## Validating realizedLpFeePct -To determine the validity of the `realizedLPFeePct` in the `FilledRelay` event, the exact same process is used as in -the identifier [`IS_RELAY_VALID`, specified in UMIP 136](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-136.md). However, instead ofing a `RateModelStore` contract to look up a deposit's rate model, we can use the `AcrossConfigStore`'s `tokenConfig` to [look up the rate model](#token-constants) for a deposit. The deposited `originToken` can be mapped to an `l1Token` by following step 2 above which can be used to query a `rateModel`. - -Moreover, instead of calling `liquidityUtilizationCurrent` and -`liquidityUtilizationPostRelay` on the `BridgePool` contract (passing no arguments) to compute the rate model, identically-named methods would be -called on the `HubPool` contract, passing in a single argument, the `l1Token` derived in the 3 step process above. - -If the `realizedLPFeePct` that is computed using those means does not match the `realizedLPFeePct` in the -`FilledRelay` event, then the relay is considered invalid. - -All valid `FilledRelay` events should then be stored for the construction of the bundle. - -# Finding Slow Relays - -To determine all slow relays, follow the following process: - -1. For all valid `FilledRelay` events above, group them by `originChainId` and `depositId`. -2. Remove all groups that contain a `FilledRelay` event where `totalFilledAmount` equals `amount`. This removes deposits that have been 100% filled. -3. Remove all groups that do not contain an event where `filledAmount` is nonzero and equal to `totalFilledAmount`. This keeps only deposits whose earliest fill is in this time range. - -For all remaining groups, they should be stored in a list of slow relay groups. - -## Computing Slow Relay payment amounts - -For a given slow relay identified [above](#finding-slow-relays), we can compute the associated deposit's "unfilled amount" as `deposit.amount - latestFill.totalFilledAmount`, where `latestFill` is the last fill chronologically for a deposit. Since each fill increments `totalFilledAmount`, the `latestFill` can also be identified by sorting all fills associated wiht a deposit and keeping the fill with the largest `totalFilledAmount`. - -Note: Since we eliminated all fills where `totalFilledAmount == deposit.amount`, the remaining "last fill" should have `totalFilledAmount < deposit.amount` AND have `totalFilledAmount > [all other fills for deposit].totaFilledAmount`. - -# Constructing the PoolRebalanceRoot - -To construct the `poolRebalanceRoot`, you need to form a list of rebalances. - -For all valid `FilledRelay` events above, group them by `repaymentChainId` and their associated `l1Token` found above. - -For each group, sum the `fillAmount` values to get the total relay repayments for that group. - -Similarly, sum the `fillAmount * realizedLPFeePct / 1e18` to get the total LP fees for that group. - -To determine the amount to modify the running balances: - -1. _Add relayer refunds_: For each `FilledRelay` [group](#finding-valid-relays), initialize a running balance value at 0 and add the total relay repayments to - it. Each running balance value is defined by its `repaymentChainId` and `l1Token`. -2. _Add slow fills_: For each [slow relay group](#finding-slow-relays), add each slow relay's [unfilled deposit amount](#computing-slow-relay-payment-amounts) to the group's running balance. -3. _Subtract deposits_: Find all `FundsDeposited` events on all `SpokePool`s from earlier within each `SpokePool`'s block range. Using the - `originChainId`, `originToken`, the `quoteTimestamp`, and the `SetPoolRebalanceRoute` event on the HubPool, use a - similar process as the 3 step one above to map this back to an `l1Token`. For that `l1Token` and `originChainId`, - initialize a running balance value if one doesn't exist already and subtract the `amount` from it. -4. _Subtract excesses from partially executed slow fills_: In the case that a previous slow fill payment was sent to a `SpokePool`, but before the slow fill leaf could be executed, a relayer partially "fast" filled the deposit. Afterwards, the slow fill leaf was executed to complete the remainder of the deposit. The `SpokePool` now has a surplus amount of tokens because the original slow fill payment was not fully used to complete the deposit, so this excess must be returned to Mainnet. This step therefore explains how to identify excesses and determine how much to send back (i.e. subtract from running balances). Find all `FilledRelay` events in the block range that have `isSlowRelay` set to true. For each, use a similar method - as above to [map this event back to an `l1Token` at the `quoteTimestamp`](#matching-l2-tokens-and-l1-tokens). Use the `destinationChainId` as the `repaymentChainId` - to determine which running balance that this event should apply to. For each previously [validated bundle](#valid-bundle-proposals), follow the steps in the ["Finding Slow Relays"](#finding-slow-relays) section - for this `originChainId` and `depositId`, and look for slow relays with a matching - `originChainId` and `depositId`. There should be exactly one slow relay payment matching the `FilledRelay` in question. This is the slow fill that was included in a previous bundle that added to the `runningBalance` and ultimately led the bundle to send a slow fill payment to the `SpokePool` on the `destinationChainId`. Compute the [slow fill amount](#computing-slow-relay-payment-amounts) sent in the older root bundle. The excess amount remaining in the `SpokePool` after this current `FilledRelay` (with `isSlowRelay = true`) is equal to `slow fill amount` minus `FilledRelay.fillAmount`. In other words, if the `FilledRelay.fillAmount` is less than the `slow fill amount` originally sent over in a prior bundle, then send back the difference. Subtract the result from the running - balance for the associated `l1Token` and `destinationChainId`. -5. _Subtract excesses from unexecuted slow fills_: This section is similar to the one above but deals with cases where the slow fill leaf can never be executed. Find all `FilledRelay` events in the block range that have `totalFilledAmount` equal to `amount` (i.e. fills that completed a deposit) and that have `fillAmount` less than `amount` (i.e. fills that were not the first fill for a deposit). If the first fill for a deposit completed a deposit (`fillAmount == amount` and `totalFilledAmount == amount`), then there can be no excess left in the spoke pool because this would not have triggered a slow fill payment to be sent to the spoke. First we need to see if the first fill for this current fill triggered a slow fill. In previously [validated bundles](#valid-bundle-proposals), identify all matching fills for the same `originChainId` and `depositId`. Find the earliest such fill. Determine the block range of the root bundle proposal that contained this fill using [this logic](#determining-block-range-for-root-bundle-proposal) for the `ProposeRootBundle` event with a `bundleEndBlock` for the `FilledRelay.destinationChainId` greater than or equal to the `FilledRelay` block number. Find the last fill in this same bundle block range. The slow fill payment for the bundle should have been `FilledRelay.amount - FilledRelay.totalFilledAmount`, same as [this calculation](#computing-slow-relay-payment-amounts). Since we know that the current `FilledRelay` in this upcoming proposal 100% filled the deposit, we know that the slow fill leaf cannot be executed, so the entire slow fill payment must be sent back to mainnet. Subtract this (the preceiding slow fill payment from a valid root bundle that this fill ultimately completed) from the running balance. - -We now need to add the preceding running balance value to the current one for a given `repaymentChainId` and `l1Token`. -For each `repaymentChainId` and `l1Token` combination, older -[RootBundleExecuted](https://github.com/across-protocol/contracts-v2/blob/a8ab11fef3d15604c46bba6439291432db17e745/contracts/HubPool.sol#L157-L166) events -should be queried to find the preceding `RootBundleExecuted` event. This means identifying the most recent `RootBundleExecuted` event with a `chainId` matching the `repaymentChainId` and [identifying the `runningBalanceValue` at the index of the `l1Token`](#matching-l1-tokens-to-running-balances-or-net-send-amounts). - -For each tuple of `l1Token` and `repaymentChainId`, we should have computed a total running balance value. The -following algorithm describes the process of computing running balance and net send amount: - -``` -spoke_balance_threshold = the "threshold" value in `spokeTargetBalances` for this token -spoke_balance_target = the "target" value in `spokeTargetBalances` for this token - -net_send_amount = 0 -# If running balance is positive, then the hub owes the spoke funds. -if running_balance > 0: - net_send_amount = running_balance - running_balance = 0 -# If running balance is negative, withdraw enough from the spoke to the hub to return the running balance to its target -else if abs(running_balance) >= spoke_balance_threshold: - net_send_amount = min(running_balance + spoke_balance_target, 0) - running_balance = running_balance - net_send_amount -``` - -Take the above running balances and net send amounts and group them by only `repaymentChainId` and sort by `repaymentChainId`. Within -each group, sort by `l1Token`.

The latter three arrays are values mapped to the `l1Tokens` entry of the same index.

This value will be used in this section as well. - -For each group from the previous section defined by a `destinationChainId` and `l1Token` that either a) has fast relays -or b) has a negative net send amount, a RelayerRefundRoot must be constructed.

For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as a official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation). A reference TraderMade implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/TraderMadePriceFeed.ts). - -Our team has adjusted the original Liquidation and Dispute bots in order to fit the interfaces of our protocol. You can find our versions of the Liquidator and Dispute bots on the following GitLab links: - -- [Liquidator Bot](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jrv_bot/packages/liquidator/test) -- [Dispute Bot](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jrv_bot/packages/disputer/test) - -TraderMade is provided as an accessible source to query for this data, but ultimately how one queries for these rates should be varied and determined by the voter to ensure that there is no central point of failure. - -In the case of a TraderMade outage voters can turn to any other available price feed API or a broker API, as the price feeds for the forementioned financial assets does not differ much between different providers. There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes. For this case, we provide options for additional price feed providers that voters could utilize. - -## Additional price feed providers - -### FXMarketAPI - -Documentation for the API can be found [here](https://fxmarketapi.com/documentation#live_rates). - -- Live price feed data -- Historical prices based on date and time -- Registration is free and provides 500 free requests -- Paid plans available -- OHLC request can be used to grab the last closing price before a weekend or a non-working day - -Example requests: - -- Live Rate for NZDUSD: `https://fxmarketapi.com/apiliveapi_key=api_key¤cy=NZDUSD` -- OHLC for a certain date on a currency pair: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=NZDUSD&date=2020-12-23&format=ohlc` -- Request for NZDUSD price at a certain date and time: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=NZDUSD&date=2020-12-23-15:50` - -### FCS API - -Documentation for the API can be found [here](https://fcsapi.com/document/forex-api). - -- 500 API Calls with Free Plan -- Live price data accessible with Free Plan - Updated every 60 seconds or less -- Historical data accessible with the Basic Paid Plan - 10$ per month - -Example requests: - -- Live Rate for NZD/USD: `https://fcsapi.com/api-v3/forex/latest?symbol=NZD/USD&access_key=api_key` -- Historical price for a certain date for NZD/USD - gives back the OHLC: `https://fcsapi.com/api-v3/forex/history?symbol=NZD/USD&period=1D&from=2020-12-23&to=2020-12-24&access_key=api_key` -- Price of NZD/USD between certain dates and times - gives a breakdown on the price each 1 minute between 12:00 and 12:30: `https://fcsapi.com/api-v3/forex/history?symbol=NZD/USD&period=1M&from=2020-12-23T12:00&to=2020-12-23T12:30&access_key=api_key` - -## Security considerations - -Adding this new identifier by itself poses a little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of NZDUSD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. diff --git a/research/uma/umips/umip-16.md b/research/uma/umips/umip-16.md deleted file mode 100644 index 9189c152..00000000 --- a/research/uma/umips/umip-16.md +++ /dev/null @@ -1,159 +0,0 @@ -# Headers -| UMIP-16 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add GASETH-1HR GASETH-4HR GASETH-1D GASETH-1W GASETH-1M as a price identifiers | -| Authors | Ali Atiia (@aliatiia), Matt Rice (@mrice32), Sean Brown (@smb2796) -| Status | Approved | -| Created | September 4, 2020 | - -## Summary (2-5 sentences) -The DVM should support requests for aggregatory gas prices on the Ethereum blockchain. - -## Motivation -The DVM currently does not support reporting aggregatory gas prices of finalized blocks on the Ethereum blockchain. - -Cost: Calculating an aggregatory statistic of gas prices on a confirmed block or range of blocks on the Ethereum blockchain is easy by virtue of the fact that all needed data is readily available on any Ethereum full node, whether run locally or accessed remotely through well-known providers such as Infura or Alchemy. Additionally, this data can be accessed through querying publicly accessible Ethereum blockchain data sets. - -Opportunity: Gas options/futures can help users and developers hedge against gas volatility allowing them to budget their gas consumption efficiently. Providing a price feed for settlement is a prerequisite. - -## Technical Specification - -The definition of this identifier should be: -- Identifier name: GASETH-1HR GASETH-4HR GASETH-1D GASETH-1W GASETH-1M -- Base Currency: ETH -- Quote Currency: GAS -- Sources: any Ethereum full node or data set of Ethereum node data -- Result Processing: Exact -- Input Processing: see Implementation section -- Price Steps: 1 Wei (1e-18) -- Rounding: Closest: N/A because the median algorithm and query as described below cannot produce numbers with higher precision than 1 Wei (1e-18). -- Pricing Interval: 1 second -- Dispute timestamp rounding: down -- Output processing: None -- Scaling Decimals: 18 (1e18) - -## Rationale - -The volatility of gas prices on Ethereum is a well-recognized problem that is only made worse by the ever increasing network congestion in recent months. This creates an opportunity for options/futures underwriters to create financial products that help decentralized applications (dApps) and their users hedge against gas price variability and have a consistent risk-minimized experience. The UMA protocol is well-positioned to provide the necessary plumbing for such products to flourish. Such products will need to rely on the DVM as a settlement layer in case of disputes. Therefore, by supporting data feeds for gas prices, the DVM opens the door for a win-win-win situation between financial products, users/dAaps, and the Ethereum network at large. - -Each transaction included in an Ethereum block pays an amount of Ether per 1 unit of gas consumed. That amount is (a) specified by a `gasPrice` parameter attached to a transaction, (b) is expressed in the smallest unit of the Ether currency which is `Wei`, and is set by the transaction submitter as a bid offered to the miners to have the transaction included. We therefore have a set of `gasPrice`s per block. - -There are two important factors to consider: (1) there is a block each 12-15 seconds in the Ethereum blockchain, and spikes in gas prices are routinely observed, and (2) miners can easily manipulate gas prices in a given block (especially in absence of a fee burn). Therefore, an aggregatory statistic needs to be computed over a sufficiently long range of blocks to proof against abnormalities whether due to extreme volatility or miner manipulation. We propose the median gas price over 1 hour (1HR), 4 hours (4HR), 1 day (1D), one week (1W), and 1 month (1M) periods _weighted by_ the gas used in a transaction. For safety and to proof against price manipulation and/or possible abnormal delays in block production, the DVM requires that a minimum number of blocks must have been mined within a given period. Otherwise, the DVM medianizes over a preset number of blocks defined in the following table: - -| Identifier | Minimum number of mined blocks | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| GASETH-1HR | 200 | -| GASETH-4HR | 800 | -| GASETH-1D | 4800 | -| GASETH-1W | 33600 | -| GASETH-1M | 134400 | - - -For example, if the GASETH-1HR is requested for `t1` = October 1st 2020 UTC 00:00:00, and the number of blocks mined between `t0` = September 30th 2020 UTC 23:00:00 and `t1` is less than 200, then the DVM medianizes over the 200 blocks mined at time <= `t1` regardless of how long (in wall clock time) it took for these blocks to be mined. - -## Implementation - -The total gas used by the blocks that were mined over the identifier specific time interval is computed. The identifier specific time interval is defined with bounds of the `timestamp` provided to DVM and the `timestamp` less 1HR (GASETH-1HR), 4HR (GASETH-4HR), 24HR (GASETH-1D), 168HR (GASETH-1W) or 720HR (GASETH-1M). Transactions in this range are also sorted by `total_gas_consumed`. - -The pseudo-algorithm to calculate the exact data point to report by a DVM reporter is as follows: - -```python -def return_median(t, N) - assert N in [1, 4, 24, 168, 720] - minimum_ranges = {1: 200, 4: 800, 24: 4800, 168: 33600, 720: 134400} # a mapping between the durations 1HR, 4HR, 24HR (1D), 168HR (1W), 720HR(1M) and the corresponding mimimum number of blocks that must have been mined within the period. - - # `t` is number of seconds since the epoch (unix time) - end_block = block.at(timestamp=t) # rounded down - offset = N - 3600*N # there are 3600 seconds/hour - start_block = block.at(timestamp=(t-offset)) - - # the DVM imposes a minimum number of blocks within a given time period to ensure safety against price manipulation - if end_block-start_block < minimum_ranges[N]: - start_block = end_block - minimum_ranges[N] - - total_gas, rolling_sum = 0, 0 - TXes = [] - - # loop over the block in the defined range starting with the least recent - for b in range(start_block, end_block, 1): - # gasUsed is in the header of each block - total_gas += b.gasUsed - for tx in b.transactions(): - gas_price = tx.gasPrice - gas_used = tx.totalGasUsed - TXes.append((gas_price, gas_used)) - - # sort transactions by gas_price ascendingly - sorted_TXes = sorted(TXes, key=lambda tup: tup[0]) - - for gas_price, gas_used in sorted_TXes: - rolling_sum += gas_used - if rolling_sum > total_gas/2: - return gas_price -``` - -An alternative method, for a DVM reporter to calculate this exact data point, would be to run the below SQL query against a public dataset of Ethereum node data such as Google BigQuery's `bigquery-public-data.crypto_ethereum.transactions` dataset. - -This query is parameterized with a UTC timestamp `t1`, a time range defined by the price identifier being used (i.e. 24HR) `N`, a lower bound of time `t2` defined by `t1 - N * 3600` and a minimum block amount `B` (explained in the *Rationale* section). - -```sql -DECLARE halfway int64; -DECLARE block_count int64; -DECLARE max_block int64; - --- Querying for the amount of blocks in the preset time range.

This is explained further in the *Rationale* section. - -These implementations are provided for explanation purposes and as convenient ways for DVM reporters to calculate the GASETH price identifiers. DVM reporters are free to develop additional implementations, as long as the implementations agree with the computation methodology defined in the *Rationale* section and specifications of the *Technical Specifications* section. - -## Security considerations - -Anyone relying on this data point should take note of the fact that manipulating the gas prices in a **specific** block or a short range of blocks is achievable by miners whether to inflate or deflate them for their own self-interest or on behalf of an attacker that bribed them to do so. The longer the range the requested statistic covers, the less the risk of manipulation is. This risk will also be significantly inhibited once [fee burn](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1559.md) is introduced in the Ethereum blockchain, because stuffing/padding blocks will have a non-zero cost even to miners (PoW) or block-producers (PoS). - -A large enough number of UMA governers should be running their full node to ensure data integrity. Relying on third-party full nodes presents a risk of manipulation of data, however if at least **one** governer is relying on their own full node, such manipulation is easily detectable. Hence, the security model here is 1-of-N which is low-risk. diff --git a/research/uma/umips/umip-160.md b/research/uma/umips/umip-160.md deleted file mode 100644 index 1a4bd2b4..00000000 --- a/research/uma/umips/umip-160.md +++ /dev/null @@ -1,142 +0,0 @@ -## Headers - -| UMIP-160 | | -| ---------------| --------------------------------------------------------------------------------------------| -| UMIP Title | Add COVENANT_V1 as a supported price identifier | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | April 22, 2022 | -| Discourse Link | [UMA's Discourse](https://discourse.umaproject.org/t/add-covenant-v1-price-identifier/1719) | - -# Summary - -The COVENANT_V1 identifier is intended to be used with an [Optimistic Distributor contract](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/financial-templates/optimistic-distributor/OptimisticDistributor.sol) to verify Covenant bribing protocol payouts.

If a value should contain `,` or `:` characters, such value should be enclosed in double quotes. If required, stringified JSON objects and arrays are also supported as valid values. The below listed key parameters will be used to instruct voters how to resolve a given price request for this identifier and request timestamp: - -- `votingPlatform`: Allows identifying on which platform bribed voters should participate. This can be either direct link to voting platform or human readable description. -- `voteProposal`: Includes all information required to identify the vote that is being bribed (human readable description). If required bribers can reference the next vote relative to the timestamp when the bribe had been first funded. -- `expirationTimestamp`: Provides ability for sponsors to claw back bribe if there is no finalized vote results available on the `voteProposal` after the set expiration timestamp. -- `bribedChoice`: Single voting choice that is covered by the bribe (e.g. YES/NO, asset in gauge proposal, etc.). -- `voteMeasurement`: Method for quantifying relative vote results for the bribed choice (from the `bribedChoice` parameter) expressed as a number ranging from 0 to 1 where 0 represents no votes and 1 means all voters had voted for the bribed choice. -- `payoutFunction`: Total payout function that defines how vote results value should be translated to total payout amount expressed as a multiplier to previously funded maximum bribe amount. This can be expressed either as formula or human readable instructions in case where more complex transformation logic is required. -- `bribeDistribution`: Bribe distribution rules to individual bribers. This should provide full instructions on: - - how to identify user addresses that have directly or indirectly (e.g. through delegation) voted on the `bribedChoice` in the `voteProposal`, - - conditions for disqualifying voters or applying minimum qualifying thresholds to user voting power, - - how to distribute bribe payout among qualifying voters, - - if and what fee amount to delegates should be applied for voters having delegated their voting power. -- `clawback`: Instructions on where to distribute the difference between maximum bribe amount and actual total payouts to voters. This can be either single recipient address or instructions on how to distribute it based on who has funded the bribe (e.g. only the first sponsor creating the bribe or proportional distribution among all sponsoring addresses if the bribing rewards had been topped). -- `errorMargin`: Numerical value representing the maximum allowed error margin (expressed as coefficient) when validating individual payouts. -- `rewardIndex`: Integer value allowing to identify `Reward` struct from the Optimistic Distributor contract that includes the maximum bribe payout. - -Whenever any of the parameters above require longer descriptions they can be hosted on IPFS and their content hash string used as parameter value instead. - -### Example ancillary data - -As an illustration one could construct bribe for QiDao Vault Incentives Gauge with following ancillary data parameters: - -``` -votingPlatform: "https://snapshot.org/#/qidao.eth", -voteProposal: "Next Vault Incentives Gauge round following the initial funding as emitted by requesting contract in RewardCreated event with matching rewardIndex.

[payoutFunction](https://ipfs.io/ipfs/bafkreifupsisnlqi2264ze6rjih3b6cpgpomwpljtlb5qk376sjc7haijm) instructions would insure that no bribe is paid below 8.33% threshold (as QI is allocated to other vaults above this minimum threshold) and constant bribe payout per 1% when above 10% score. [bribeDistribution](https://ipfs.io/ipfs/bafkreidmvkovrgi2jvhxgjvn6b4d6wydhlvsab2742e7b5rpvedmvtifem) document details how to distribute the payout among participating voters and also covering vote delegation with 20% delegate fee. - -# Implementation - -`COVENANT_V1` price responses represent whether the proposed bribe payout distribution is valid. If any of **must** conditions in this UMIP is not fulfilled the proposed payout should be considered invalid. If the proposed payout is invalid, the price should be `0`. If the proposed payout is valid, the price should be `1`. *Note*: all price values should be scaled by `1e18` if responding programmatically, but Optimistic Oracle and Voting dApps scales them for the users. - -Price requests for `COVENANT_V1` price identifier should be only made through Optimistic Oracle since its resolvement requires verifying event data emitted by the Optimistic Distributor contract in the same transaction when the price is requested to the Optimistic Oracle. In case of dispute UMA voters would need to identify this original price request transaction through the stamped `ooRequester` and `childChainId` parameters to the ancillary data. - -Since the functioning of `COVENANT_V1` price identifier relies on the hard-coded protocol fee recipient address the price request **must** originate only from Polygon deployment of the Optimistic Distributor contract. - -Voters should first resolve all ancillary data parameter values either directly or through the included IPFS content hash strings. In case any of the required parameters (all listed in the Ancillary Data Specifications section except for `clawback` and `errorMargin`) is missing or their values/instructions cannot be interpreted unambiguously bribe should be refunded to its sponsor and voters should validate such price request against instructions in the Refund instructions section (though Technical verification still applies). - -## Status of bribed vote proposal - -1. Identify the voting proposal being bribed from the `votingPlatform` and `voteProposal` parameters. -2. Determine whether the voting proposal being bribed had been opened for voting and irreversibly resolved at or before the cut-off time from the `expirationTimestamp` parameter. In case the vote was not resolved on time the bribe should be refunded to its sponsor and voters should validate such price request (made after `expirationTimestamp`) against Refund instructions section. -3. If the price request was made at or before the cut-off time from the `expirationTimestamp` the voting proposal being bribed **must** have been irreversibly resolved at or before the `expirationTimestamp`. This condition also applies when the voting proposal had been withdrawn and the proposal to refund the briber can be made only after the `expirationTimestamp`. - -## Technical verification - -This section provides instructions to verify if the proposed payout distribution matches the provided bribe funding and all individual payouts include valid Merkle proofs verifying them against the proposed Merkle root. - -1. Collect data on the proposed bribe payout distribution by inspecting `rewardToken`, `maximumRewardAmount`, `merkleRoot` and `ipfsHash` parameters emitted by the Optimistic Distributor contract in the same transaction when price was requested on the Optimistic Oracle. -2. `ipfsHash` **must** represent a valid IPFS content hash for the IPFS hosted file listing actual bribe payouts. -3. Bribe payouts file referenced by `ipfsHash` **must** contain at least a list of bribe payout recipient addresses, individual bribe amounts and their Merkle proofs (array of `bytes32` values represented as hex strings) for each recipient. -4. Sum of individual bribe amounts in the bribe payout file **must** exactly match the `maximumRewardAmount` (as it also includes the remainder to be returned to the sponsor). It is expected that by default bribe payouts are raw amounts that do not need any scaling and can be directly compared to the value of `maximumRewardAmount`. Though, in case human readable payouts were provided voters should first scale them up to their raw representation using the `decimals` parameter from the `rewardToken` contract. -5. It is expected that the bribe payout file includes `accountIndex` parameter for each recipient and they **must** be unique non-negative integers across all payout set. If `accountIndex` is not provided then voters should assign it continuously for each recipient starting from 0. -6. Calculate leaf data for each individual bribe payout by taking Keccak-256 hash over the ABI converted and tightly packed parameters of recipient address, bribe amount and `accountIndex`. In `web3.js` this can be achieved by using: - - ``` - web3.utils.soliditySha3( - { value: recipientAddress, type: "address" }, - { value: bribeAmount, type: "uint256" }, - { value: accountIndex, type: "uint256" } - ); - ``` -7. Verify each individual bribe payout by traversing a Merkle tree up from its leaf (calculated is Step 6 above) using its corresponding Merkle proofs: - - The process should start by taking the leaf and the first element of the Merkle proofs array. - - Order both above from lowest value to highest and concatenate them to get `bytes64` value. - - Perform Keccak-256 hash on the concatenated `bytes64` to get the next Merkle branch. In `web3.js` one can use `web3.utils.soliditySha3` method. - - Continue by taking the next element from the Merkle proofs array, pair it with the obtained Merkle branch from the previous step and Keccak-256 hash their ordered concatenation to get the next Merkle branch. - - Repeat the above procedure for all elements of the provided Merkle proofs array. The last obtained hash **must** exactly match the `merkleRoot` for all individual bribe payments. - -## Economic verification - -This section provides instructions to verify proposed payout amounts against expected bribe amounts following provided instructions from ancillary data except for cases when bribe should be refunded to the sponsor(s). - -1. Follow instructions passed from the `voteMeasurement` parameter to quantify the voting results for the bribed choice (from `bribedChoice` parameter). If the voting proposal does not include the bribed choice the result should be resolved to 0. In any case the results of following `voteMeasurement` instructions should be floored at 0 and capped at 1. -2. Follow the instructions passed from the `payoutFunction` (or apply the formula) to convert obtained voting results to payout amount expressed as a multiplier to previously funded maximum bribe amount. In any case the results should be floored at 0 and capped at 1. -3. Multiply the obtained value above with the `maximumRewardAmount` and round it to the nearest integer to obtain gross payout (before fees) in raw units of `rewardToken`. -4. Subtract the calculated gross payout above from the `maximumRewardAmount` to obtain claw-back amount claimable by the bribe sponsor(s): - - In case `clawback` parameter is provided in ancillary data and it contains a single address then assign the calculated claw-back amount to this address. - - If `clawback` parameter provides other instructions, follow them to assign how claw-back amount should be distributed among sponsors. - - If `clawback` parameter is missing or its value cannot be interpreted unambiguously then by default entire claw-back amount should be assigned to the original sponsor funding the the bribe. This can be obtained by calling `rewards` method on the Optimistic Distributor contract with the `rewardIndex` from ancillary data as input parameter. The obtained `Reward` struct will contain the `sponsor` address as its second element. Note that in case other sponsors have topped up the bribe by funding the same `rewardIndex` with the `increaseReward` method they would not receive any clawed-back bribe amounts. -5. Calculate protocol fee as 2% from gross payout amount in rounded raw units of `rewardToken`. Assign Covenant protocol fee collector address 0x104E3a4FbbDdf02843f30ADF145F661f68Afd1F4 on Polygon as its recipient. -6. Calculate total net payout to users by subtracting protocol fee amount from the gross bribe payout. -7. Follow the instructions passed from the `bribeDistribution` parameter to assign net bribe amount calculated above to individual recipients. This should involve: - - Identify user addresses and their voting power that have directly voted for the `bribedChoice` in the bribed `voteProposal`. - - If instructed, exclude any disqualifying recipients (e.g. due to split-vote or minimum voting threshold). - - Assign part of net bribe payout to direct voters based on provided instructions (e.g. proportional to voting power, any maximum payout limits to individual users, equal to all qualifying voters, etc.). - - If instructed, identify users that had delegated their voting power and assign their net bribe amounts from the previously calculated delegate bribe. If instructed apply the provided delegation fee to be held by the delegates. - - Apply any other instructions provided in the `bribeDistribution` parameter. This can involve rules for distributing any remainder from total payout in case any qualifying conditions or maximum payout limits to individual users have been applied (e.g. how to split it among other users or just reducing total payout amount and adding them to sponsor's claw-back amount). -8. Compile the expected bribe payout amount list by recipient addresses including sponsor(s) claw-back (Step 4), protocol fee recipient (Step 5) and voters/delegates (Step 7). -9. Validate proposed payouts (as verified in the Technical verification section) against expected payouts from Step 8: - - All recipient addresses in the proposed payout file **must** have a matching recipient from expected payouts, though some of smaller expected payouts could be excluded in the proposed payout file due to rounding. - - For each individual address recipient from the proposed payout file calculate the modulus for its proposed payout amount (in raw units of `rewardToken`) difference with the expected payout for the same address and divide it over its expected payout. This coefficient **must** not exceed the maximum allowed error margin passed as `errorMargin` parameter. If `errorMargin` is not provided in ancillary data then fall back to default allowed error margin of `0.0001` for this comparison. - -## Refund instructions - -In case required ancillary data parameters are missing or their values/instructions cannot be interpreted unambiguously the bribe should be refunded to its sponsor(s). This also applies in cases when the bribed vote has not been resolved (or has been withdrawn altogether) at or before the `expirationTimestamp`. In these scenarios one should perform the instructions in the Economic verification section as if the `payoutFunction` in Step 2 resulted in value of 0 and entire `maximumRewardAmount` should be distributed only among bribe sponsor(s) (identified in Step 4). Also, such refund proposal should be verified against the Technical verification section. - - -## Security considerations - -The security of this price identifier is highly dependent on bribers providing unambiguous instructions through ancillary data parameters. In order to mitigate this it is expected that Covenant bribing market operator would impose restrictions on standard allowed ancillary data parameters through its front-end. - -In order to ensure right incentives for independent verifiers to check proposed bribe payouts the operator of Covenant bribing market should impose adequate Optimistic Oracle bond amounts and liveness periods that are consistent with the complexity of expected verification operation. - -Users of this price identifier should be aware that IPFS storage on itself does not guarantee persistent data availability. Even though the operator of Covenant bribing market would attempt to ensure data availability within reasonable time period users can provide pinning of linked IPFS files on their nodes or at least save a local copies of files linked in ancillary data and Merkle proofs for claiming the payouts. - -Bribers of Covenant protocol should be aware that not all voting platforms enforce that vote results directly translate to transaction execution on-chain and might require certain trust assumptions on the organizers of the vote to execute it properly. The execution risk hence is outside the scope of this price identifier that tracks only the resolved voting scores and payouts to individual voters. diff --git a/research/uma/umips/umip-161.md b/research/uma/umips/umip-161.md deleted file mode 100644 index 22127f79..00000000 --- a/research/uma/umips/umip-161.md +++ /dev/null @@ -1,49 +0,0 @@ -**UMIP-161** - -- **UMIP title:** Add MAGIC as collateral currency -- **Author:** Mr.Bahama -- **Status:** Approved -- **Created:** 26 May 2022 - -## Summary (2-5 sentences) - -This UMIP proposes adding MAGIC for use as collateral in UMA contracts. - -## Motivation - -MAGIC token is economic infrastructure for various play-to-own games using TreasureDAO.

SPACs have only a limited period during which they may consummate a Business Combination, generally not exceeding 24 months. A SPAC generally focuses upon one industry or sector, but may maintain flexibility to engage in transactions in other industries or sectors if necessary or appropriate. More information about SPACs can be found [here](https://spac.guide/spacbasics/) and [here](https://www.spacanalytics.com/).

-A good way to capitalize on such momentum growth without having to analyze hundreds of SPACs is to take advantage of the movement of the index value that includes stocks of the most active SPACs.
- -The selection of **10** stocks of the most active SPACs included in the basket of the proposed uSPAC10 index is made according to [spacHero database top-10 gainers](https://www.spachero.com/). spacHero is a free SPAC resource for retail investors. [**spacHero – Rapidapi.com**](https://rapidapi.com/spachero/api/spachero-spac-database/) is an official spacHero SPAC API with live rankings, SPAC target names, merger meetings, warrant redemption deadlines, price targets, SEC filings, investor presentations and more.
- -Underlying assets are traded on the NYSE and NASDAQ, but reliable sources of quotations are either paid or provide data with a delay.
-We suggest using the [**Mboum Finance – Rapidapi.com**](https://rapidapi.com/sparior/api/mboum-finance) API as the main source of quotes, which has both free and paid tariff plans, and also provides historical price data.
- ->**Rapidapi.com** Finance APIs allow end-users a variety of service options for their accounts as well as to stay current on events and news that impact their portfolios and financial security. For example, a finance API could remotely connect them to their bank account to initiate deposits, transfers, or other transactions. Other financial APIs include stock market news and trading platforms, cryptocurrency markets, and more. A financial API provides a secure link from a consumer to the databases and transactional servers of the institutions with which they do business. Application programming interfaces, or APIs, are the digital links between data providers and end-users. In the financial sector, security is essential as sensitive information is transferred in real-time, so only the most robust protocols are utilized to protect the data transmitted on both ends.

- -### Weekend timestamp -Over the weekend or some official holidays the REST API does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). -Due to unavailability of price feed for stock exchange rates over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. -If a request timestamp takes place on a weekend or any other day the stock market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. -### Stock markets working hours -Underlaying assets trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. -### Price feed -Our price-feed provider’s API documentation can be found [here](https://rapidapi.com/sparior/api/mboum-finance).

List Criteria: Addresses that have voted in over 90% of UMA DVM Votes in the 365 days previous to the price request. Decentra-List Revision ID = 1.` - -When this ancillary data dictionary is stored as bytes, the result would be: `0x446f20616c6c2050726f706f73656420416464726573736573206d65657420746865204c697374204372697465726961206174207468652074696d65206f662074686520707269636520726571756573743f204c6973742043726974657269613a204164647265737365732074686174206861766520766f74656420696e206f76657220393025206f6620554d412044564d20566f74657320696e207468652033363520646179732070726576696f757320746f2074686520707269636520726571756573742e20446563656e7472612d4c697374205265766973696f6e204944203d20312e20` - -# Rationale - -Decentra-List allows users to propose revisions to the list by proposing addresses for addition or removal from the list. The proposed revisions are then sent to the Optimistic Oracle for verification that they meet the list criteria. The price requests sent to the Optimistic Oracle only verify that the proposed revision is correct as per the list criteria. It does not verify that addresses on the list not included in the revision are correct, nor does it verify that the current revision includes all addresses that should be added or removed from the list. - -It is intended that Decentra-List will only execute revisions that are provably correct as per the list criteria. As such, there are only 2 price return values provided: `1` is used for revisions that are provably "YES" and will be executed by Decentra-List and `0` is used for "NO" or "CAN NOT BE DETERMINED" and Decentra-List will reject revisions with this returned price value. - -Every Decentra-List price request to the Oracle will start with a question, either "Do all Proposed Addresses meet the List Criteria?", or "Do all Proposed Addresses fail to meet the List Criteria?", depending on whether the proposed revision is to add or remove addresses to the list. These questions have been constructed so that every single address must be a "YES" for the correct Oracle response to be "YES" or `1`. For example, if a Decentra-List user proposes a revision that would add 4 addresses to the list where 3 addresses meet the criteria, but 1 address does not, the correct Oracle response would be `0` and the revision would be rejected by Decentra-List with no new addresses added to the list. - -Whether an address meets a list's criteria may change over time. Proposed Addresses should be evaluated against the list criteria at the timestamp of the price request. To make this clear, the question posed in the ancillary data includes, "at the time of the price request". - -# Implementation - -1. Voters should decode the ancillary data to get the list criteria and the Revision ID needed to get the list of Proposed Addresses. -2. Voters should find the array of Proposed Addresses as below: - - Navigate to the Decentra-List dapp, select the network of the price request and connect their wallet. - - Select the List address from the drop down to display information about that List. The List address can be found in the requester field of the oracle price request. - - Open the Pending Revisions drop down and find the Proposed Addresses for the Revision ID provided in the Oracle price request ancillary data. -3. Voters should evaluate the array of Proposed Addresses against the List Criteria provided in the ancillary data to answer the question provided in the ancillary data. The List Criteria provided in the ancillary data could contain directions on data sources, verification scripts, etc. If so, that information should be used. Otherwise, the voter should determine how to verify whether the Proposed Addresses meet the given List Criteria. -4. Voters should return `1` if the answer to the question in the ancillary data is provably "YES". Voters should return `0` if the answer to the question is "NO" or "CAN NOT BE DETERMINED". - -# Security Considerations - -This construction allows Decentra-List users flexibility in creating new lists with custom criteria, bond amounts and liveness periods. The list criteria will be used for all revisions to the list and can not be edited. List creators should be careful to construct the list criteria, so a deterministic outcome can be reached for all Proposed Addresses. List creators should also be careful to set the bond amount and liveness period large enough to provide disputers sufficient time and financial incentive to review all Proposed Addresses (up to 99 addresses can be included in a single revision). - -There are also potential contract-level attacks that could result from people intentionally setting up Decentra-List lists dishonestly to their advantage. As a rule, any contracts that reference a Decentra-List list smart contract, should review the list properties and this UMIP beforehand. diff --git a/research/uma/umips/umip-17.md b/research/uma/umips/umip-17.md deleted file mode 100644 index d44ff428..00000000 --- a/research/uma/umips/umip-17.md +++ /dev/null @@ -1,60 +0,0 @@ -## Headers -| UMIP-17 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add rDAI as a collateral currency | -| Authors | Jeff Bennett (endymionjkb@gmail.com), Sean Brown (@smb2796) | -| Status | Approved | -| Created | September 25, 2020 | - -## Summary (2-5 sentences) -This UMIP will add rDAI (redeemable Dai) to the supported collateral currencies to the AddressWhitelist contract, allowing UMA users to mint synthetics using rDAI as the collateral currency. This UMIP will also add a flat final fee to charge per-request. The proposed final fee is 400 rDAI per request. - -## Motivation -One of the most basic use cases for synthetic tokens is derivitives tied to underlying real-world assets, including equities - and a popular way to gain exposure to equities is through ETFs or index funds: baskets of securities chosen according to a published set of criteria. - -Increasingly, and particularly among millennials, those criteria involve moral judgments and values. "Value driven investment" funds (e.g., the ETHO Climate Leadership Index) represent a rapidly rising trend in the industry, and often outperform the broader market. - -An UMA synthetic tied to an "ESG" index would be a great way to "long the environment." But an even greater way would be to use rDAI as collateral for the index position, designating an environmental charity (e.g., Offsetra or rTrees) as the beneficiary. That way, the charity always benefits, even if the index underperforms. (Perhaps especially then, if position holder needs to deposit more rDAI to avoid liquidation.) - -Of course, this idea can be generalized beyond ESG, to any pairing of a charitable cause to a related ETF or index fund. And since new charities are partnering with rDAI all the time - in fact, through the rDAI protocol anyone can create an arbitrary "charity" simply by providing a list of ETH addresses and weights - this is a growth industry. - -A local charitable organization could create a monthly "rolling" synthetic that directed funds according to the organization's priorities that month, either by altering weights, or by creating a new list of beneficiaries. - -Alternatively, the protocol also allows rDAI to be used without specifying charitable beneficiaries at all. Undesignated ("self-hat") rDAI could be used simply to offset potential losses and de-risk positions, as the collateral would naturally increase over time. Hybrid positions are also possible; e.g., 50% going to charity, and 50% compounding within the synthetic. - -When using undesignated ("self-hat") rDAI as collateral for the EMP contract template, a contract sponsor would need to set `excessTokenBeneficiary` to an address they wish to receive the accrued rDAI interest. The EMP function trimExcess would then need to be called to drain the excess collateral to the `excessTokenBeneficiary`. See below for possible security implications of this approach. - -## Technical Specification -To accomplish this upgrade, two changes need to be made: -- The rDAI address, [0x261b45d85ccfeabb11f022eba346ee8d1cd488c0](https://etherscan.io/token/0x261b45d85ccfeabb11f022eba346ee8d1cd488c0) on Mainnet, needs to be added to the collateral currency AddressWhitelist introduced in UMIP-8. - (This is the address of the proxy contract, which is the token that gets transferred.) -- A final fee of 400 rDAI needs to be added for rDAI in the Store contract. -## Rationale -This change encourages wider adoption of the UMA protocol through strengthening ties with traditional financial markets, and promoting a new use case: securing synthetic positions with interest-bearing collateral that benefits charities related to the underlying assets. - -It also provide general utility by enabling the use of "compounding collateral," which serves to lower risk, offset losses, and monetize "HODLing" of inactive synthetic positions (as the first such tokens are likely to be), or those with far future expiration dates. -400 rDai was chosen because the current final fee for DAI is 400 DAI and the value of rDAI is directly equal to the value of DAI. -## Implementation -This change has no implementation other than adding the rDAI address to the collateral currency AddressWhitelist and adding the rDAI final fee to the Store contract. - -## Security considerations - -rDAI collateral providers should do their own due diligence on the beneficiaries of any given synthetic before opening a position. This is easy to do on a technical level, since all the "hat"-related information, including the literal Ethereum addresses of recipients, is available on-chain through the token contract interface and corresponding subgraph. (Not to mention the graphical rDAI explorer.) rDAI held in positions would be tamper-proof, as it is owned by the synthetic contract. These addresses (ideally linked to ENS domains) could then be verified through the official web sites of the charitable organizations. -rDAI itself should present very little risk. It is an ERC-20 token based on DAI, and the project was audited by Quantstamp: -https://certificate.quantstamp.com/full/r-token-ethereum-contracts - -The "logic" contract referenced by the proxy is also upgradeable, in case any issues are found. rDAI is hard-pegged to DAI, so in that sense is as safe to hold as DAI. - -One of the intended uses of rDAI collateral is in support of synthetics based on ESG (or other value driven investment strategies aligned with supported charities), and this not been a common use case. So far, most synthetics (e.g., those issued by UMA) have been crypto-pairs enabling leveraged positions, or simple yield instruments such as uUSD. - -Market liquidity for these new instruments will likely be low at first, and there may be insufficient DVM participation to ensure the solvency of positions. Investors would also be dependent on published financial data for the underlying ETFs (constituents, weights, and prices), which is less available and reliable than, say, the ETH-BTC price. These synthetics may therefore be riskier than other types of synthetics, and those minting such contracts should take care to set appropriate collateralization requirements, perhaps based on the measured volatility of the underlying indices. - -However, this is not the only use case for rDAI in synthetics. Simply using it for compounding collateral is even "safer" than DAI itself, as the collateralization ratio would gradually increase, with no action required from the position holder (other than calling the function to apply accrued interest). - -Note that the expected behavior - directing interest on all future positions to the "advertised" hat, which is the stated purpose of and motivation for users of the synthetic - depends on separate calls to the rDAI and UMA protocols, and this introduces order dependencies and timing considerations. - -The hat inheritance feature of rDAI ensures that all rDAI deposited through opening positions will adopt the hat associated with the contract address, and this gets assigned the first time rDAI is transferred to the contract. So in order to set the contract's hat, the creator must open an initial position, sending in rDAI with the "advertised" hat, using a three-step mint/deploy/deposit process. If the last two steps are not done atomically, an attacker could "hijack" the synthetic by opening a position before the creator, with the hat set to the attacker's wallet - in which case all interest would go to the attacker instead of the charity. - -As described above, a creator could implement a "management fee" - capturing a portion of all interest payments - by either setting one of the recipients in the hat to an account controlled by the creator (in which case `payInterest` would directly transfer funds), or by setting one of the recipients to the contract address and `excessTokenBeneficiary` to the wallet address (in which case `payInterest` would transfer rDAI to the contract, and the creator could withdraw it with `trimExccess`). In the latter case, the minter needs the EMP contract address, so the process would be deploy/mint/deposit, all of which should be done atomically. (Technically, the EMP contract address could be precomputed using the deployer address and nonce, in which case the creator could still use the regular mint/deploy/deposit sequence.) - -In any case, the hat id and recipient addresses assigned to an address are publicly visible, so if such an attack did occur, it could be easily discovered, and avoided by simply abandoning the contract. \ No newline at end of file diff --git a/research/uma/umips/umip-170.md b/research/uma/umips/umip-170.md deleted file mode 100644 index b6a79b4d..00000000 --- a/research/uma/umips/umip-170.md +++ /dev/null @@ -1,102 +0,0 @@ -## Headers - - -| UMIP-170 | | -| -------------- | ------------------------------------------------------------------------ | -| UMIP Title | Add `ASSERT_TRUTH` as a supported price identifier | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | January 30th, 2023 | -| Discourse Link | https://discourse.umaproject.org/t/feat-add-assert-truth-identifier/1900 | - -# Summary - -The DVM should support price requests for the `ASSERT_TRUTH` price identifier. `ASSERT_TRUTH` is intended to be used as - a default price identifier for UMA's [Optimistic Oracle V3 contract](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/optimistic-oracle-v3/implementation/OptimisticOracleV3.sol) - that allows asserters to make claims about the state of the world.

To this end, the result of an assertion can only be true or false, and an assertion is resolved only after the liveness period has expired or, in the case of a dispute, after it has been settled in the Oracle.

The update has been thoroughly reviewed and tested, and is ready for deployment. - -## Security considerations - -The `OptimisticOracleV3` only has the ability to send price requests to the DVM, so in the event of a serious bug, the biggest security implication would be that end-users would be able to send requests to the DVM without paying the final fee. diff --git a/research/uma/umips/umip-173.md b/research/uma/umips/umip-173.md deleted file mode 100644 index a2811bf0..00000000 --- a/research/uma/umips/umip-173.md +++ /dev/null @@ -1,127 +0,0 @@ -## Headers - -| UMIP-173 | | -| ---------- | --------------------------------------------------------------------------------------------------------------------- | -| UMIP Title | Approve DVM upgrade to DVM2.0 | -| Authors | Chris Maree (chris@umaproject.org), Pablo Maldonado (pablo@umaproject.org), Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | October 26, 2022 | -| Discussion | [Discourse](discourse.umaproject.org/t/approve-dvm-upgrade-to-dvm-2-0/1935) | - -## Summary - -This UMIP proposes an upgrade to the UMA Data Verification Mechanism (DVM) that re-works core parts of UMA's tokenomics. -At a high level, this upgrade adds a new staking and slashing mechanism wherein voters earn a pro-rata share of emissions -for staking and are slashed for voting wrong (or not voting). This upgrade also re-works a number of other DVM contracts -such as an updated governor, proposer contract and new designated voting contract. Finally, this upgrade has a new -emergency recovery mechanism to the DVM that enables emergency admin proposals to bypass the DVM's schelling point -oracle system in the event of an emergency. More detail on the individual changes are broken down in the sections that -follow. - -## Motivation & Rationale - -The current UMA tokenonomics suffers from a few issues that the proposed upgrade aims to address: - -1. The current system has a flaw wherein an attacker can create spurious votes with the intention of capturing UMA inflation - rewards. This becomes an issue when the rewards a voter receives exceed the cost of the final fee (currently ~$500). - In practice, this means that you need to be voting with ~72k UMA (at an UMA price of $2.25 and considering average vote - participation over a number of recent votes) to profit from creating spurious votes. - -2. It is currently hard to work out the APY a voter receives for participating in the UMA system. One needs to consider - the number of other UMA involved in votes and, crucially, estimate how many voting rounds per period of time there will be - to work out an implied APY. This is difficult as the number of requests (and the resultant emissions) changes depending - on externalities that can't easily be modelled. This also poses complexities when working out the UMA inflation over time as - it is so dependent on the number of requests. Ideally, the UMA supply inflation (and the associated voter APY) are easy - to find and are not a function of the number of requests. - -3. The current UMA tokenomics does not distinguish between price requests and governance actions. Ideally, the DVM - should treat governance actions as democratic and avoid the schelling point penalty for voting against the majority in these - requests. - -4. Today the DVM has no way of enforcing dynamic rewards for participation depending on dynamics of a given vote. - For example, we might want to penalize non-participation more if a vote is contentious. Ultimately, it would be useful to - have a more flexible mechanism for the conditions under which a voter is rewarded (or punished.) - -5. Lastly, the current UMA tokenomics does not incentivize the locking up (staking) of UMA. The DVM and UMA token interplay - should drive up the UMA token price through the removal of liquid UMA through a staking mechanism. This should also make - UMA more anti-fragile to price shocks and general market movements through the removal of liquidity. Additionally, the - current UMA system is not resistant to an adversarial take over as as soon as someone is able to capture the control - of the DVM and use it to vote an incorrect outcome they can dump UMA on the open market before the cost of corruption - comes in to effect (the attacker has a time advantage over other market participates to react). - -The proposed upgrade aims to address all of the identified issues, as well as adding in some additional nice-to-haves. A -full list of the functionality change is listed below: - -1. New DVM participation incentives: - 1. Staking rewards are emitted at a constant rate per second. This means you can work out the overall UMA inflation over time and stakers can easily work out their APY for staking in the system. This emission is shared pro-rata among all stakers. - 2. Slashing mechanism that redistributes tokens from inactive and wrong voters to the stakers who have resolved the vote correctly. This hardens the schelling point by adding a more punitive cost function with being wrong. - 3. Dynamic slashing library that can configure the amount slashed as a function of vote participation metrics. For example, the system could be configured to slash non-participates more highly the more contentious a vote is. The configuration of this module is left up to UMA governance and can be changed later via a DVM vote. - 4. Governance votes are treated as a special price request category where slashing mechanism is not applied. -2. Automatic spam protection mechanism where any non-governance votes that do not meet required participation and - agreement thresholds for a number of rounds (set by UMA governance) would be deleted. This allows voters to create a - schelling point around treating a request as spam by not voting on it. -3. Recovery mechanism where bonded emergency proposals can be executed short-circuiting the normal voting mechanism. This enables the DVM to recover from any kind of internal failure mode that could occur (breakage in the commit reveal system, contract issues or other) through a permissionless upgrade flow. -4. First class vote delegation support enabling a 1 to 1 relationship between the delegator and delegate wallets. This lets a voter delegate from a secure cold storage wallet to a hot wallet. The hot wallet can commit, reveal and claim and re-stake their rewards but can't access the underlying stake. More complex delegation systems (e.g. pooled UMA staking with delegate voting) can be built on top of this externally to the core UMA contracts, if desired. -5. Governance proposals can now include ancillary data, allowing for better identifying information to be included with vote proposals. -6. Price requests now contain a unique identifier, enabling easier tracking and support in front ends. -7. A number of gas optimizations were made throughout the protocol. - -## Implementation & Technical Specification - -This UMIP upgrades the following contracts in the UMA DVM system: - -1. Core DVM voting contract: `Voting.sol` → `VotingV2.sol` (implementation [here](https://github.com/UMAprotocol/protocol/blob/3ad31b3aab3cf342f6a91dce54032fe0ee1b15c8/packages/core/contracts/data-verification-mechanism/implementation/VotingV2.sol)). -2.

The upgrade involves proposing a number of upgrade transactions to the DVM that are then executed. These transactions involve a number of detailed steps (and the exact implementation can be found [here](https://github.com/UMAprotocol/protocol/blob/master/packages/scripts/src/upgrade-tests/voting2/1_Propose.ts)) and are briefly mentioned below: - -1. Changing the minter permissions on the UMA token -2. Adding the new governor as the owner of the voting token -3. Transferring UMA tokens held by old governor to the new governor -4. Transferring ownership of the finder to the [VotingUpgraderV2.sol](https://github.com/UMAprotocol/protocol/blob/master/packages/core/contracts/umip-helpers/VotingUpgraderV2.sol). This contract is used in a number of subsequent steps to ensure that the upgrade process is atomic. -5. Transfer ownership of existing voting to voting upgrader -6. Temporarily add the Governor as a contract creator -7. Register the ProposerV2 as a verified contract -8. Register the GovernorV2 as a verified contract -9. Transfer ownership of all remaining ownable contracts to the voting upgrader -10. Transfer all multirole ownership to the voting upgrader -11. Reset governance ownership to the voting upgrader for both the old and new governor -12. Execute upgrade through the voting upgrader. This is deployed [here](https://etherscan.io/address/0x13852D4AF390d8C3404c0577fd8B8E43389A290b). - -When executed, these transaction have the effect of moving all internal ownership to the voting upgrader contract and using this to upgrade the UMA DVM system atomically. Please see the linked upgrade scripts that outline the upgrade process in detail. The prior DVM (Voting) will no longer be used once it has been migrated, although unclaimed rewards from the previous contract can still be claimed using the new DVM 2.0. The migration will not not involve any interruption of the functionality of contracts using the DVM (OOv2, OO, etc.), as they will continue to function with DVM 2.0 after migration. - -Note that the upgrade transaction that calls into the `votingUpgraderV2` contract also contains a permissioned function `canRun` that blocks all accounts other than a known UMA account from executing this upgrade. This was done to ensure that that we can delay the execution of the upgrade in the event other price requests come in. - -## Security considerations - -The upgraded DVM contracts listed above have been audited by Open Zeppelin in two separate audits ([report1](https://blog.openzeppelin.com/uma-dvm-2-0-audit/), [report2](https://blog.openzeppelin.com/uma-dvm-2-0-incremental-audit/),[report3]()).

The UMIP-176 proposes a new way of handling the SHERLOCK_CLAIM price identifier that is aligned with the current implementation of the Sherlock Claim Manager. - -Sherlock is a DeFi audit marketplace and smart contract coverage protocol built on Ethereum. It provides audits by top security experts and offers optional coverage for audited contracts. In the claim lifecycle, Sherlock utilizes UMA's Optimistic Oracle and Data Verification Mechanism (DVM) for escalated claim resolution. - -In the event of a potential exploit, Sherlock’s security team will work with the protocol to determine the nature of a hack. If the protocol believes they experienced an exploit that should be covered by Sherlock, the protocol will submit the block range of the exploit and the amount to be reimbursed by Sherlock. Next, Sherlock’s claims committee will work to evaluate the nature of the potential exploit and then map the exploit to the coverage terms agreed to with that protocol. The committee will then decide whether to pay out the claim. If the committee decides not to pay out the claim, the protocol has the option to stake a minimum dollar amount ($50k for example) and escalate the claim to the UMA Data Verification Mechanism. The UMA tokenholders would then use information provided by the protocol, the claims committee, and importantly, security expert not associated with Sherlock in an unbiased way, to decide whether the claim should be paid out or not. - -Sherlock documentation can be found [here](https://docs.sherlock.xyz/). - -## Ancillary Data Specifications - -``` -Metric:Sherlock exploit claim arbitration, -Protocol:, -ChainId:, -Value:, -StartBlock:, -Resources:, -CoverageAgreement: -``` - -Example: - -``` -Metric:Sherlock exploit claim arbitration, -Protocol:UMA Protocol, -ChainId:1, -Value:1000000, -StartBlock:13207345, -CoverageAgreement:Link to protocol specific coverage agreement with Sherlock -``` - -## Rationale and usage - -The framing of the price identifier puts the responsibility on the protocol to specify the correct information in the ancillary data as described in Ancillary Data Specifications. If any of the information is not accurate, a payout will not occur. This is mitigated by the idea that a protocol will get up to 3 chances to correctly input the data in order to successfully trigger a payout. - -Because the potential request space is broad, it is possible that voters will not be able to arrive at a definitive result. In this case, the default return value should be `deny` (or `0`), which likely will also result in no payout from Sherlock to the claimer. This places the onus on the protocol to provide clear evidence that an exploit occurred. - -It is low risk for UMA voters to return a value of `0` if there is insufficient evidence to prove the claim with accuracy, as it is likely that this will result in a resubmission of the price request by the claiming protocol once they have have accumulated more concrete evidence of their claim. If a claim is paid out in error, there is little recourse for Sherlock at that point, so it seems reasonable that a protocol should have to prove that a payout occurred and that the default should be to `deny`, meaning a payout is not enacted. - -## Implementation - -1. Voters should decode the ancillary data and identify the protocol, chain, start block, dollar value of claim in question and any additional resources provided. -2. Because the protocol making the claim will likely be the party constructing the ancillary data and submitting a price request, voters should heavily rely on checking external resources for additional context. The Sherlock Coverage Terms Agreement should always be referenced. Additionally the Protocol's original claim as well as the Sherlock Claims Committee's original claims decision will likely always be published and should be referenced. Sherlock's Coverage Agreement details the exact types of exploits that Sherlock covers, and these should be the only exploits that are considered in arbitration. More information is provided in the `Additional Resources` section below. -3. Voters should return the USD `Value` within ancillary data converted to USDC decimals (the decimal USD value multiplied by 10e6) an thus `approve` the claim if they determine that: - 1. There was an exploit for the `Protocol` specified. - 2. The exploit type is covered by Sherlock's Coverage Agreement. - 3. The exploit happened as part of the `StartBlock` specified in ancillary data. - 4. The total USD value lost in the exploit is greater than or equal to the USD `Value` within ancillary data. -4. If voters cannot confidently assess one of the criterion above, they should return a value of `0` to `deny` the claim. - -## Additional Resources - -While the coverage agreement document between Sherlock and the protocol in question will serve as the canonical guideline as to whether an exploit falls under coverage or not, it is non-trivial to determine whether an exploit occurred, and how that exploit maps to the coverage agreement. - -Outside of the coverage agreement, UMA tokenholders should rely on 3 sources of information when making their decision: - -1. The interpretation of the exploit and coverage agreement by the Sherlock claims committee and other persons associated with Sherlock. -2. The interpretation of the exploit and coverage agreement by the protocol in question. -3. Most important, the interpretation of the exploit and coverage agreement by third party security experts. - -While information in 1) and 2) should be readily available (both parties will be motivated to explain their interpretation), we can reasonably expect 3) to be readily available as well based on historical public interest in protocol exploits and past articles produced. - -Sources of 3) could be [rekt.news](https://twitter.com/RektHQ), [Mudit Gupta](https://twitter.com/Mudit__Gupta), [Kelvin Fichter](https://twitter.com/kelvinfichter), [Igor Igamberdiev](https://twitter.com/FrankResearcher), as well as audit firms such as [PeckShield](https://twitter.com/peckshield) as long as the parties don’t have material connection to either Sherlock or the protocol in question. - -## Implementation & Technical Specification - -This UMIP proposes a governance transaction that perform the following actions atomically: - -- Remove the `SHERLOCK_CLAIM` identifier by calling `removeSupportedIdentifier(bytes32 identifier)` method of IdentifierWhitelist contract found [here](https://etherscan.io/address/0xcF649d9Da4D1362C4DAEa67573430Bd6f945e570) with the hexadecimal representation of the `SHERLOCK_CLAIM` identifier as a parameter. -- Add again the `SHERLOCK_CLAIM` identifier by calling `addSupportedIdentifier(bytes32 identifier)` method of IdentifierWhitelist contract found [here](https://etherscan.io/address/0xcF649d9Da4D1362C4DAEa67573430Bd6f945e570) with the hexadecimal representation of the `SHERLOCK_CLAIM` identifier as a parameter. - -## Security Considerations - -It should be noted that this price identifier is objectively complex and broad and will likely require a large amount of active participation from UMA voters to correctly analyze and resolve these requests. UMA voters should not be expected to be security experts, and therefore do not accept any liability from potential claims from either the claiming protocol or Sherlock. UMA voters should only be expected to act as an impartial jury; their responsibility is to synthesize information from ancillary data, `Additional Resources`, Sherlock's coverage terms and ad hoc information provided by Sherlock and the claiming protocol during arbitration, but not to perform complete security analysis themselves. - -There are also several mitigating processes built into the Sherlock system as well as the UMA voting system. As noted previously, claiming protocols will have up to 3 total chances to submit claims and go to a DVM vote. This should allow for comprehensive information gathering and analysis, and will allow UMA voters to default to a `0` return value unless clear supporting evidence is provided either to support or contradict a claim. - -The DVM voting system also allows for a multi-day discussion and information gathering process. Because of this reason, it seems acceptable that the potential price request space for this identifier is broad and potentially subjective. Both the claiming protocol, as well as Sherlock's security committee will have the opportunity to provide supporting evidence and advocate for their case. It is recommended that both parties be active in UMA's #voting [Discord channel](https://discord.gg/YE4h2YAb), as this is where most UMA voting discussion occurs. diff --git a/research/uma/umips/umip-177.md b/research/uma/umips/umip-177.md deleted file mode 100644 index 3e5bf53c..00000000 --- a/research/uma/umips/umip-177.md +++ /dev/null @@ -1,154 +0,0 @@ -## Headers - -| UMIP 177 | | -| --- | --- | -| UMIP Title | ROPU_ETHx | -| Authors | Gabriel Astieres | -| Status | Draft | -| Created | 03/04/23 | -| Discourse Link | | - -# Summary - -The DVM should support price requests for ROPU_ETHx. ROPU_ETHx reflects violations of the MEV-policy committed by validators of the ETHx staking protocol.

It will also verify that the `Violations` it contains are legitimate **based on the rules that define what a violation is**. - -```solidity -mapping(uint256 => Report) public reports; // Mapping of the reports against their ID. -``` - -**A report is of the following form:** - -```solidity - struct Report { - uint32 fromEpoch; - uint32 toEpoch; - uint256 timestamp; - bytes32 assertionID; - Violation[] listViolations; - } -``` - -- `fromEpoch`: Is the Beacon Chain's epoch number at which the given report starts. -- `toEpoch`: Is the Beacon Chain's epoch number at which the given report ends. -- `timestamp`: Is the timestamp at which the RatedOracle noticed that the report was challenged on the Optimistic Oracle. If the report is not challenged during the appropriate time window, this value is 0. -- `assertionID`: ID of the claim associated to this report on the UMA Optimistc Oracle. -- `listViolations`: The list of violations flagged between `fromEpoch` to `toEpoch` on the Beacon Chain. - -**A violation is represented with the following struct:** - -- `validatorIdentifier`: The element allowing ETHx to identify which validator is concerned by this violation. The value is the `keccak256` hashed public key of the concerned validator. -- `epochNumber`: The Beacon Chain's epoch number at which the violation occurred. -- `penaltyType`: A number describing which kind of penalty to apply to this validators based on ETHx’s MEV policy. -- `newFeeRecipientAddress`: The address the validator broke the policy with. This should be different to the address that a validator is expected to share rewards with. - - ```solidity - struct Violation { - bytes32 validatorIdentifier; - uint32 epochNumber; - uint32 penaltyType; - address newFeeRecipientAddress; - } - ``` - -# Rationale - -The list of MEV policy violations committed by validators of the ETHx set is reported on a 24-hour cadence and stored on a Rated smart-contract. - -Each of those daily reports will be the object of a claim on the Optimistic Oracle. When a new claim is created, a bytes representation of the report ID is included in the Ancillary Data field. The Oracle is then responsible for verifying that the associated violations list is complete and that the included violations meet the criteria described in the implementation section. The list should be empty if no violations were found. - -The report covers a specific time period, start and end designated by an epoch number of the beacon chain. Only events that occurred during this time period are considered when evaluating the report. The claim is marked as correct only if all the violations are appropriate, and none have been missed. - -A violation is made of 4 elements: `validatorIdentifier`, `epochNumber`, `penaltyType`, `newFeeRecipientAddress` that were described in the previous section. All those 4 elements should be reflecting the reality of what happened on chain to be considered correct. - -It's important to note that a validator's status regarding the ETHx MEV policy may change over time. Therefore, proposed and missed violations should be evaluated against the validator's state at the time of the suspected violation. - -# Implementation - -In order for voters to determine the validity of the claim, they should refer to the following contracts: - -- The Rated smart contract, which is the original creator of the claim. -- The ETHx config, which lists all the addresses of the ETHx protocol. Information needed to get validators’ state will be held in `PermissionlessNodeRegistry` and `PermissionedNodeRegistry`. On Ethereum mainnet, this contract is deployed at `0x4ABEF2263d5A5ED582FC9A9789a41D85b68d69DB`. - -**The steps to evaluate a report are the following:** - -1. Voters should decode the ancillary data to get the corresponding `ID` of the report to examine. -2. Voters should read the storage of the Rated smart contract in the `reports` mapping to access the corresponding report. -3. Voters should get from the report what time window it covers. Using `fromEpoch` and `toEpoch` marking when it begins and ends using Beacon Chain epoch numbers. -4. Voters should access the list of `Violations` contained in the report. If the list is empty, this means that no violations were found for the given period. -5. For each of the `Violation` contained, voters should attest to its accuracy. -To do so, voters should search for validators from the ETHx protocol who proposed blocks during the relevant time period. If these validators received MEV or priority fees payments, they should have received them at predetermined addresses based on whether they belong to the `Permission-less` or `Permissioned` pool and whether they opted-in to the socialisation of MEV rewards. A table of acceptable payment addresses for each scenario is provided below. -When a block is coming from an MEV-relay, the `newFeeRecipientAddress` should be the end of block transfer that the builder used to pay the proposer. However, in some instances, builders pay the proposer through an internal transaction. In such cases, when the appropriate ETHx address is paid, this does not constitute a violation. More on this new form of payment in this [Rated post](https://feedback.rated.network/p/updating-ethereum-el-mev-boost-rewards-attribution-methodology-to-capture). -6. Finally, if voters identify any violations that occurred during the period and were not reported, the report should be considered incomplete, and the claim should be marked as false. - -| Penalty type | Pool type | Socializing pool opt-in | Expected fee recipient address | -| --- | --- | --- | --- | -| 1 | Permission-less | No | Permission-less socialising pool OR Operator’s EL reward vault address | -| 2 | Permission-less | Yes | Permission-less socialising pool | -| 3 | Permission-less | Opted-out in the last 3 epochs* | Permission-less socialising pool | -| 4 | Permission-less | Opted-out more than 3 epochs ago* | Permission-less socialising pool OR Operator’s EL reward vault address | -| 5 | Permission-less | Opted-in in the last 3 epochs* | Permission-less socialising pool OR Operator’s EL reward vault address | -| 6 | Permission-less | Opted-in more than 3 epochs ago* | Permission-less socialising Pool | -| 7 | Permissioned | n/a | Permissioned socialising Pool | - - -💡 \* 3 epochs exclusive between the reported violation and opt-in/out action of the operator. - -💡 The fee recipient addresses on the ROPU report should be different than those on the table above, for their respective penalty types. - -### An example: - -This transaction is a new report brought by Rated on chain: [transaction](https://goerli.etherscan.io/tx/0xd767d6b92354273068c4078028c86f37f0e89754f7f56fe590b2edd42fac5a5f) - -The new report creates a claim on the Optimistic Oracle v3. - -![umip-177_a](./images/umip-177_a.png) - -This claim is linked to the report number 5 on the Rated Oracle. The voters should retrieve the content of this report by reading the **`reports`** mapping in the Rated Oracle. - -![umip-177_b](./images/umip-177_b.png) - -The voters should also look for the violations contained in the said report by calling the getter **`getViolationsInReport`:** - -![umip-177_c](./images/umip-177_c.png) - -Now that those value were retrieved, the voters have all the elements to determine the validity of the report. As seen above, this report covers the period of time between epoch `176809` and `176829` of the beacon chain (prater in this example). - -In this example, the report contains 1 violation. It is said to be perpetrated on epoch `176819`. Indeed, this block was proposed by a validator from the ETHx set. This validator’s pubkey is `0x810e0df7e6b08dbb0528099432fc4e60acbc5a2f5bc3d6e3559c1003dc58137de0ff2e868e5ec414d7f4e0886cf096d4` and the Validator Identifier is correct, this can be checked by calling the pure function `getPubkeyRoot`. - -This validator belongs to the permission-less pool. Voters have therefore to check that either the transaction at the end of the block or the fee recipient is one of acceptable addresses as defined in the previous table. For this slot, the recipient of the transaction at the end of the block is `0x6da4c7af13ecb85c5283b0b78fbd3c204efb2c0c` which is the ETHx permissionless socializing pool. Therefore, this validator did not violate the ETHx policy, and this does not constitue a valid violation, making this example report incorrect. - -# Security Considerations - -When resolving a dispute, the process in the DVM shall ensure two things at once: - -- (i) That every violations presented in the associated report are correct. -- (ii) That the report is complete and that it includes every violation in the time frame concerned. - -Also, the Rated Smart Contract, expects the disputed reports to settle in less than 4 days, considering a new vote every 2 days and 2 days long process.

ABT inherits directly from a standard WETH9 implementation, and wraps the transferFrom() function to apply custom transfer logic. This permits Across to realise a permissioned set of HubPool proposers, thereby reducing the attack surface of Across. All other ERC20 functions are completely standard. - -## Motivation - -Across relies on an Optimistic Asserter proposal pattern in order to verify that any proposed allocation of HubPool funds is valid and correct. Across proposers submit a proof as part of their proposal, which can be permissionally verified and optionally disputed by any observer of the system. Proposals that survive a 2 hour challenge window are subsequently able to be executed, thereby resulting in the movement of funds. - -As with disputing, it is currently permissionless to propose a root bundle proposal in Across. This unfortunately provides an opportunity for malicious third-parties to submit invalid proposals in order to extract funds from the system. This marginal risk dictates the need for a lengthy challenge window on proposals in order to ensure that any such proposals are detected and disputed. This thereby reduces the number of proposals that can be made and ultimately limits the frequency at which Across HubPool funds can be allocated to bridging activities, such as refunding relayers for user deposits that they have filled. - -The Across Bond Token has been designed specifically to enhance the security of Across by limiting the set of possible Across proposers, whilst still allowing any independent observer to dispute an invalid proposal. By ensuring that proposals only originate from pre-approved actors, Across will have reduced its attack surface and will therefore be able to reduce its 2 hour challenge window. This will allow Across to scale further by reducing the time that relayers must wait for refunds, thereby improving their capital efficiency, and will ultimately deliver a better experience for the users of Across. - -## Technical Specification - -The following changes are proposed: - -- The ABT address [0xee1DC6BCF1Ee967a350e9aC6CaaAA236109002ea](https://etherscan.io/address/0xee1DC6BCF1Ee967a350e9aC6CaaAA236109002ea) shall be added to the collateral currency list introduced by UMIP-8. -- A final fee of 0.135 shall be configured for ABT in the relevant Store contract (nominally [0x54f44eA3D2e7aA0ac089c4d8F7C93C27844057BF](https://etherscan.io/address/0x54f44eA3D2e7aA0ac089c4d8F7C93C27844057BF). - -## Rationale - -The final fee of 0.135 matches the existing WETH final fee. ABT can be minted and redeemed at a rate of 1:1 against Ether. - -## Implementation -ABT implements a simple mechanism that restricts the set of possible proposers, whilst still allowing for permissionless disputes. It achieves this be overriding the WETH9 transferFrom() function in order to implement custom transfer logic, such that it prevents any non-approved address from transferring any amount of ABT to the Across v2 HubPool contract if they are recorded as the current proposer. This effectively prohibits Across HubPool proposals by any non-approved addresses. All other ERC20 functionality is inherited directly from a local WETH9 implementation. - -The set of permitted proposers will be configurable and the can be managed by the ABT contract owner. The fact that proposers must be known to Across in advance significantly reduces the probability of an incorrect proposal being submitted, and thereby provides opportunity for the proposal challenge window to be reduced. - -Migration to the ABT token for use as a bond collateral token will successfully retain the existing security properties of Across whilst dramatically reducing the attack surface area that malicious proposers might seek to exploit. - -## Security considerations - -This collateral type has been developed in-house by the Across team to address a specific need with respect to the proposal lifecycle. Its capabilities are limited to basic ERC20 functions, and it inherits most of its functionality from the WETH9 contract that has previously been used within the UMA ecosystem. The token has been [audited by OpenZeppelin](https://blog.openzeppelin.com/uma-across-v2-audit), with only minor typographical errors found. The ABT contract is not upgradeable, and no marginal risks to the UMA ecosystem have been identified. - -Contract deployers considering using this collateral in an UMA contract should refer to the [guidelines on collateral type usage](https://docs.umaproject.org/uma-tokenholders/guidence-on-collateral-currency-addition) to ensure appropriate use. diff --git a/research/uma/umips/umip-179.md b/research/uma/umips/umip-179.md deleted file mode 100644 index 4bd6e3ba..00000000 --- a/research/uma/umips/umip-179.md +++ /dev/null @@ -1,826 +0,0 @@ -# Headers -- UMIP 179 -- Title: Update the **ACROSS-V2** price identifier to support Across v3 -- Author paul@across.to -- Status: Last Call -- Created: 2023-02-17 -- Discourse Link: N/A - -# Summary -This UMIP defines the updated protocol specification for Across V3.

SVM numbers are encoded as little-endian, so the byte order is reversed compared to EVM. | -| uint256 | [u8; 32] | Used for numbers that cannot possibly fit into 64 bits. This is used for deposit IDs and foreign token amounts. Here the byte order is big-endian matching the EVM representation. | -| uint32 | u32 | Used for numbers that fit into 32 bits. SVM numbers are encoded as little-endian, so the byte order is reversed compared to EVM. | -| bytes | Vec<u8> | Used for arbitrary byte arrays. In SVM this is encoded as the first 4 bytes holding the length of the array (little-endian encoded) followed by the array byte items. | - -Also note that SVM uses snake case for struct field names compared to camel case in EVM. - -### V3RelayData -The `V3RelayData` type underpins the transfer of funds in or out of a SpokePool instance. `V3RelayData` is defined as follows: -| Name | Type | Description | -| :--- |:---- | :---------- | -| depositor | bytes32 | The address that made the deposit on the origin chain. | -| recipient | bytes32 | The recipient address on the destination chain. | -| exclusiveRelayer | bytes32 | The optional exclusive relayer who can fill the deposit before the exclusivity deadline. | -| inputToken | bytes32 | The token that is deposited on the origin chain by the depositor. | -| outputToken | bytes32 | The token that is received on the destination chain by the recipient. | -| inputAmount | uint256 | The amount of inputToken that is deposited by the depositor. | -| outputAmount | uint256 | The amount of outputToken that is received by the recipient. | -| originChainId | uint256 | The chain ID of the origin SpokePool. | -| depositId | uint256 | The ID identifying a deposit on the origin chain. | -| fillDeadline | uint32 | The Unix timestamp on the destination chain after which the deposit can no longer be filled. | -| exclusivityDeadline | uint32 | The optional Unix timestamp on the destination chain after which any relayer can fill the deposit. | -| message | bytes | Optional data that is forwarded to the recipient as part of a relay. | - -#### Note -- `V3RelayData` specifies `bytes32` representation for addresses (`depositor`, `recipient`, ...) in order to interface with non-EVM chains. The EVM address supplied shall be promoted to type `bytes32` with the upper 12 bytes zeroed. - -#### SVM support - -`RelayData` in SVM represents the same data as `V3RelayData` in EVM: - -| Name | Type | -| :--- |:---- | -| depositor | Pubkey | -| recipient | Pubkey | -| exclusive_relayer | Pubkey | -| input_token | Pubkey | -| output_token | Pubkey | -| input_amount | u64 / [u8; 32] | -| output_amount | u64 / [u8; 32] | -| origin_chain_id | u64 | -| deposit_id | [u8; 32] | -| fill_deadline | u32 | -| exclusivity_deadline | u32 | -| message | Vec<u8> | - -`input_amount` and `output_amount` types depend on their use case: -- little-endian encoded `u64` for native token amounts (`input_amount` for deposits and `output_amount` for fills) -- big-endian encoded `[u8; 32]` for foreign token amounts (`output_amount` for deposits and `input_amount` for fills) - -### V3RelayDataLegacy -The `V3RelayDataLegacy` type is supported for backwards compatibility, but is slated for deprecation. `V3RelayDataLegacy` has the following delta to the `V3RelayData` type: -| Name | Type | -| :--- |:---- | -| depositor | address | -| recipient | address | -| exclusiveRelayer | address | -| inputToken | address | -| outputToken | address | -| depositId | uint32 | - -### FillStatus -A mapping of `RelayData` -> `FillStatus` is stored within each SpokePool instance. This mapping can be queried with the hashed `V3RelayData` for a deposit, allowing the status for the corresponding fill to be queried. - -| Name | Value | Description | -| :--- | :---- | :---------- | -| Unfilled | 0 | The SpokePool has no known state for the corresponding `V3RelayData` hash. | -| RequestedSlowFill | 1 | A SlowFill request has been made for this V3RelayData hash. A corresponding `RequestedV3SlowFill` event has been previously emitted. | -| Filled | 2 | A fill (fast or slow) for this `V3RelayData` hash has been completed. | - -#### SVM support - -`RelayData` and its destination `chain_id` are mapped to a `FillStatus` via `FillStatusAccount` that is a PDA (Program Derived Address) derived from `svm_spoke` program ID using the string `fills` and 32 byte `relay_hash` as the seeds. `relay_hash` is computed using `solana_program::keccak` over the `RelayData` and `destination_chain_id` as described in SVM support of [Computing RelayData Hashes](#computing-relaydata-hashes). - -`FillStatusAccount` stores following fields: - -| Name | Type | Description | -| :--- |:---- | :---------- | -| status | FillStatus | The status of the mapped fill, see below. | -| relayer | Pubkey | Address of the relayer that made the fill to control who can close this PDA. | -| fill_deadline | u32 | Fill deadline to control when this PDA can be safely closed. | - -`FillStatus` is an enum with the same values as in EVM, but one should consider the fact that on SVM it is only useful for internal program logic as the `FillStatusAccount` can be closed by the relayer after the fill deadline has passed, so the status is not persisted onchain indefinitely. In order to reconstruct the status of a fill, one should look for `FilledRelay` and `RequestedSlowFill` events in all transactions where the `FillStatusAccount` was involved (`getSignaturesForAddress` RPC method can be useful). If there are no such events, then the fill can be considered `Unfilled`. If the `FilledRelay` is found as the last event, then the fill is considered `Filled`. If there is only a `RequestedSlowFill` event, then the fill is considered `RequestedSlowFill`. - -### FillType -A FillType instance is emitted with each `FilledV3Relay` event (see below). - -| Name | Value | Description | -| :--- | :---- | :---------- | -| FastFill | 0 | The relay was completed by a relayer as a fast fill. | -| ReplacedSlowFill | 1 | The relay was initially requested to be completed via slow fill, but was subsequently fast-filled by a relayer. | -| SlowFill | 2 | The relay was completed via slow fill. | - -#### SVM support - -`FillType` enum is emitted with each `FilledRelay` event on SVM with the same interpretation as when emitted with `FilledV3Relay` events on EVM. - -### V3RelayExecutionEventInfo -A V3RelayExecutionEventInfo instance is emitted with each `FilledV3Relay` event (see below). - -| Name | Type | Description | -| :--- |:---- | :---------- | -| updatedRecipient | bytes32 | The recipient of the funds being transferred. This may be the `recipient` identified in the original deposit, or an updated `recipient` following a `RequestedSpeedUpV3Deposit` event. | -| updatedMessageHash | bytes32 | The hash of the updated message sent to the recipient. This is computed as `keccak256(message)` where `message` is the `message` bytes in the `RelayData`. If the updated `message` field is empty, this will be set to `bytes32(0)`. | -| updatedOutputAmount | uint256 | The amount sent to `updatedRecipient` by the relayer completing the fill. | -| fillType | FillType | Type of fill completed (see `FillType` above). | - -#### SVM support - -`RelayExecutionEventInfo` instance is emitted with each `FilledRelay` event on SVM similar as `V3RelayExecutionEventInfo` in `FilledV3Relay` events on EVM: - -| Name | Type | Description | -| :--- |:---- | :---------- | -| updated_recipient | Pubkey | The recipient of the funds being transferred. This always matches the original recipient as there is no speedup functionality in the `svm_spoke` program. | -| updated_message_hash | [u8; 32] | The hash of the message sent to the recipient. This is computed as `solana_program::keccak::hash(message)` where `message` is the `message` bytes in the `RelayData`. If the `message` field is empty, this will be set to `[0u8; 32]`. | -| updated_output_amount | u64 | The amount of the tokens being transferred. This always matches the original amount as there is no speedup functionality in the `svm_spoke` program. | -| fill_type | FillType | Type of fill completed (see `FillType` above). | - -### V3SlowFill -A `V3SlowFill` instance is used to calculate slow relay root when proposing and verifying the root bundle. It is also passed as `slowFillLeaf` parameter to the SpokePool `executeSlowRelayLeaf` call upon executing a slow fill: - -| Name | Type | Description | -| :--- |:---- | :---------- | -| relayData | V3RelayData | `V3RelayData` instance to uniquely associate the SlowFill with `V3FundsDeposited` and `RequestedV3SlowFill` events. | -| chainId | uint256 | The chain ID of the SpokePool completing the SlowFill. This is used only when proposing and verifying the root bundle while on execution SpokePool overrides it with its actual chain ID. | -| updatedOutputAmount | uint256 | The amount sent to `recipient` as part of a SlowFill. This should typically be equal to or greater than the `V3FundsDeposited` `outputAmount`. | - -#### Notes -The `updatedRecipient` field is normally set to the `recipient` from the corresponding `V3FundsDeposited` event. In the event that the relayer completes the fill with an accompanying `RequestedSpeedUpV3Deposit` event, `updatedRecipient` will be set to the address approved by the update. - -#### SVM support - -A `SlowFill` instance is used to calculate slow relay root when proposing and verifying the root bundle. It is also passed as `slow_fill_leaf` parameter to the `svm_spoke` `execute_slow_relay_leaf` instruction upon executing a slow fill: - -| Name | Type | Description | -| :--- |:---- | :---------- | -| relay_data | RelayData | `RelayData` instance to uniquely associate the `SlowFill` with `FundsDeposited` and `RequestedSlowFill` events. | -| chain_id | u64 | The chain ID of the SpokePool completing the `SlowFill`. This is used only when proposing and verifying the root bundle while on execution `svm_spoke` overrides it with its configured chain ID similar as in EVM. | -| updated_output_amount | u64 | The amount sent to `recipient` as part of a `SlowFill`. | - -## Events -Across V3 defines the following events: -- FundsDeposited -- V3FundsDeposited -- RequestedSpeedUpDeposit -- RequestedSpeedUpV3Deposit -- FilledRelay -- FilledV3Relay -- RequestedSlowFill -- RequestedV3SlowFill -- ClaimedRelayerRefund - -`svm_spoke` program uses Anchor's [`emit_cpi`](https://www.anchor-lang.com/docs/features/events#emit_cpi) macro to emit events that are comparable with EVM events. On SVM Across supports only a subset of events as explicitly documented in the relevant subsections below. - -### Event Deprecation -The following events are marked for deprecation. See [Migration](#migration) for more information. -- V3FundsDeposited -- RequestedSpeedUpV3Deposit -- FilledV3Relay -- RequestedV3SlowFill - -### FundsDeposited, V3FundsDeposited -The `FundsDeposited` event extends the `V3RelayData` type and `V3FundsDeposited` event extends the `V3RelayDataLegacy` type by applying the following adjustments: - -| Name | Type | Description | -| :--- | :--- | :---------- | -| originChainId | omitted | This field is omitted from the `FundsDeposited` and `V3FundsDeposited` events. | -| destinationChainId | uint256 | Chain ID indicating where this deposit should be filled. | -| quoteTimestamp | uint32 | Timestamp that determines the fee paid by the depositor. | - -#### Note -- Consumers of these events should append the `originChainId` in order to avoid unintentionally mixing events from different chains. -- The `FundsDeposited` and `V3FundsDeposited` `outputToken` field is not required to be a known HubPool `l1Token`.

In addition, the encoded `SlowFillLeaf` must be prefixed with 64 bytes of zeroes to protect against any possibility of an EVM leaf being used on SVM or vice versa. - -## Definitions - -### Deposits -A `Deposit` is defined as an instance of either of the following events: -- `FundsDeposited`. -- `V3FundsDeposited`. - -#### SVM support - -On SVM chains a `Deposit` is defined as an instance of `FundsDeposited` event. - -### Fills -A `Fill` is defined as an instance of either of the following events: -- `FilledRelay`. -- `FilledV3Relay`. - -#### SVM support - -On SVM chains a `Fill` is defined as an instance of `FilledRelay` event. - -### Slow Fill Requests -A `Slow Fill` is defined as an instance of either of the following events: -- `RequestedSlowFill`. -- `RequestedV3SlowFill`. - -#### SVM support - -On SVM chains a `Slow Fill` is defined as an instance of `RequestedSlowFill` event. - -### RelayData -`RelayData` is defined as an instance of etiher of the following data types: -- `V3RelayData`. -- `V3RelayDataLegacy`. - -#### SVM support - -On SVM chains, `RelayData` is defined as an instance of the `RelayData` data type as described in the supported SVM [Data Types](#data-types) section above. - -### Bundle Block Range -The `Bundle Block Range` is the pair of start and end blocks for a given proposal. See [Identifying Bundle Block Ranges](#identifying-bundle-block-ranges) for guidance on identifying the `Bundle Block Range`. - -#### SVM support - -On SVM chains the `Bundle Block Range` is the pair of start and end slots. - -### Fill Status -A `Deposit` is considered to be `Filled` on the destination chain when the destination `SpokePool` `FillStatus` mapping shows state `Filled` for the `Deposit` `RelayData` hash. - -#### SVM support - -A `Deposit` is considered to be `Filled` on the destination SVM chain when its `FillStatus` is resolved to `Filled` using `FillStatusAccount` as described in the supported SVM [Data Types](#data-types) section above. - -## Method -### Identifying SpokePool Contracts -The current SpokePool address for a specific chain is available by querying `HubPool.crossChainContracts()`. The chainId must be specified in the query. In case of SpokePool migations, historical SpokePool addresses can be identified by scraping HubPool `CrossChainContractsSet` events. - -#### SVM support - -The procedure for identifying the current SpokePool program for a specific SVM chain is as follows: - -1. Query the `HubPool` contract for the `crossChainContracts()` mapping using the `chainId` of the SVM chain to get the address of chain specific `adapter` contract. -2. Query the `adapter` contract for the `SOLANA_SPOKE_POOL_BYTES32()` method to get the `bytes32` representation of SVM program ID. -3. Convert the `bytes32` representation to a Base58 encoded `Pubkey` of SVM SpokePool program. - -In case of SpokePool migrations, historical SpokePool addresses can be identified by scraping HubPool `CrossChainContractsSet` events and querying the previous `adapter` contract. - -### Identifying "Lite" deployments -We consider a deposit to "originate" or be "destined for" a "Lite chain" if the `LITE_CHAIN_ID_INDICES` value in the AcrossConfigStore includes the deposit's origin chain or destination chain respectively as of the deposit's `quoteTimestamp` field. These chains impose constraints on relayer repayments and slow fills. - -### Resolving SpokePool tokens to their HubPool equivalent -For the purpose of identifying the equivalent HubPool token given a SpokePool token, the following shall be followed: -1. Find the latest `SetRebalanceRoute` event with a block timestamp at or before the relevant HubPool block number, where the relevant SpokePool chain ID and token address match the `SetRebalanceRoute` `destinationChainId` and `destinationToken` fields. - - In the case of a `Deposit` event, the relevant HubPool block number is identified by resolving the `quoteTimestamp` to a HubPool block number. -3. From the resulting `SetRebalanceRoute` event, select the associated `l1Token` field. -4. Search the `SetPoolRebalanceRoute` events for the same `l1Token` and `destinationChainId` at or before the applicable HubPool block number. -5. Using the `l1Token` value found in step 2, search for the latest `SetRebalanceRoute` event at or before the applicable HubPool block number where `l1Token` and `destinationChainId` that match the extracted `l1Token` and SpokePool chain ID. If a match is found, the addresses match and are considered cross-chain equivalents. - -#### SVM support - -Convert Base58 encoded `Pubkey` of SVM chain SpokePool token to its `bytes32` representation and convert to EVM address by trimming off the first 12 bytes. Use this EVM token address representation as the `destinationToken` following the instructions in the generic [Resolving SpokePool tokens to their HubPool equivalent](#resolving-spokepool-tokens-to-their-hubpool-equivalent) section above. The integrators should be aware of this SVM address trimming and bear the responsibility to use the correct SVM token address that would correctly resolve to the `l1Token` address. - -### Identifying Bundle Block Ranges -In addition to the description [UMIP-157](https://github.com/UMAprotocol/UMIPs/blob/pxrl/umip179/UMIPs/umip-157.md#determining-block-range-for-root-bundle-proposal): -- Proposers may opt to reduce the size of the proposal block range for each chain in the event that RPC provider data inconsistencies are detected, and -- A "soft pause" of a chain is permitted in the event that the proposer cannot safely increment the bundle block range, or has no events to propose beyond the previous bundle block range. In this case, the proposer may repeat the procedure for - DISABLED_CHAINS by proposing from and to the previous bundle end block. - -#### SVM support - -Bundle block ranges for SVM chains are identified by their slot numbers. For the end slot, only such slot should be used that has a corresponding block produced for it. - -### Reconstructing FilledRelay messages -The `FilledRelay` event emits the `messsageHash` field. This field is set as follows: -- When the `RelayData` `message` field is empty (`0x`): `bytes32(0)`, OR -- When the `RelayData` `message` field is non-empty (`0x...`): `keccak256(message)`. - -#### SVM support - -The `FilledRelay` event on SVM emits the `message_hash` field. This field is set as follows: -- When the `RelayData` `message` field is empty: `[0u8; 32]`, OR -- When the `RelayData` `message` field is non-empty: `solana_program::keccak::hash(message)`. - -### Computing RelayData Hashes -A `RelayData` hash is computed as the `keccak256` hash over the ABI-encoded representation of the arguments `relayData`, `destinationChainId`, where: -- `relayData` is of type `V3RelayData` or `V3RelayDataLegacy`. -- `destinationChainId` is of type `uint256`. - -- When the `FilledRelay` event data omits the `message` field, the `message` field shall be populated according to the procedure specified in [Reconstructing FilledRelay messages](#resonstructing-filledrelay-messages). - -#### Note -- This method produces the identical hashes for `V3RelayData` and `V3RelayDataLegacy` for the same input data due to `address` promotion to `bytes32` prior to hashing. - -#### SVM support - -A `RelayData` hash on SVM is computed as the `solana_program::keccak` hash over the Borsh serialized representation of concatenated `relay_data` and `destination_chain_id`, where: -- `relay_data` is derived from `RelayData` replacing the `message` field (type Vec<u8>) with its `message_hash` (type [u8; 32]) as described in the SVM support for [Reconstructing FilledRelay messages](#reconstructing-filledrelay-messages) section above, and -- `destination_chain_id` is little-endian encoded `u64` representation of destination chain ID. - -### Computing Relayer Repayments & Depositor Refunds -For the purpose of computing relayer repayments, the following procedures are completed: -- Validating Fills -- Validating Pre-Fills -- Finding Expired Deposits -- Finding Unfillable Deposits - -#### Note -- Depositor refunds are issued via the Relayer Repayment workflow. - -### Validating Fills -Each of the `Fills` emitted within the `Bundle Block Range` on a destination SpokePool shall be considered valid by verifying that: -1. The `Fill` event `FillType` field is not set to `SlowFill`, AND -2. The component `RelayData` maps exactly to one or more corresponding `Deposit` events emitted on the relevant `originChainId`, AND -3. The corresponding `Deposit` event occurred within or before the `Bundle Block Range` on the origin chain SpokePool. - -#### Note -- If the `Deposit` event specifies `outputToken` `bytes32(0)` (i.e. the Zero Address), the equivalent SpokePool token on the destination chain shall be substituted in. For the purpose of determining `RelayData` equivalency, the updated/substituted `outputToken` shall be used in place of the Zero Address. If there is no equivalent SpokePool token on the destination chain at the `Deposit` `quoteTimestamp`, then any fill for this deposit will not be repaid regardless of whether it is fillable on the destination. -- `RelayData` equality can be determined by comparing the keccak256 hashes of two `RelayData` objects. -- Fills of type `SlowFill` are valid, but are not relevant for computing relayer repayments. - -#### SVM support - -When validating fills between EVM and SVM chains, one should consider the differences in the field naming, types and encodings used on SVM chains as described in the supported SVM [Data Types](#data-types) section above. In order to compare the `RelayData` one should be able to safely convert between EVM and SVM representations as in practice all amounts should fit into 64 bits. - -### Validating Pre-fills -For each of the `Deposits` emitted within the `Bundle Block Range` where no corresponding `Fill` is identified on the destination chain within the `Bundle Block Range`, identify the valid `Fill` according to the following criteria: -1. Verify that the destination chain `FillStatus` for the `Deposit` `RelayData` is `Filled` as at the destination chain end block number for the proposal. -2. Resolve the corresponding `Fill` on the destination chain. -3. Verify that the `FillType` is `FastFill` or `ReplacedSlowFill` AND that the `Fill` occurred prior to the current the `Bundle Block Range` on the destination chain SpokePool. - -#### Note -- No specific method is prescribed for resolving the `Fill` on the destination chain. An `eth_getLogs` request can facilitate this, and if required, the `Bundle Block Range` could be narrowed by a binary search over the `FillStatus` field. This is left as an implementation decision. - -#### SVM support - -In order to resolve the `Fill` on the destination SVM chain, one can inspect transactions where the `FillStatusAccount` PDA was involved (using `getSignaturesForAddress` RPC method) as described on the SVM supported [Data Types](#data-types) section above and looking for the emitted `FilledRelay` event. - -### Finding Expired Deposits -For the purpose of computing depositor refunds, each `Deposit` shall be considered expired by verifying that: -1. The `fillDeadline` timestamp elapsed within the `Bundle Block Range` on the destination SpokePool (i.e. the `fillDeadline` expired between the `block.timestamp` of the destination chain's bundle start and end block), -2. The `FillStatus` on the destination SpokePool is set to `Unfilled` or `SlowFillRequested` as at the end of the `Bundle Block Range`. - -#### Note -- Expired deposits shall be refunded to the `depositor` address on the origin SpokePool. -- Depositor refunds are to be issued as part of the relayer refund procedure. -- The `fillDeadline` timestamp shall be resolved to a block number on the destination chain in order to determine inclusion within the `Bundle Block Range`. - -#### SVM support - -When evaluating if the `fillDeadline` / `fill_deadline` timestamp elapsed within the `Bundle Block Range` on the SVM destination SpokePool, one can use `getBlock` RPC method for the destination chain's bundle start and end slot and use the `blockTime` field to compare against the `fillDeadline` / `fill_deadline` timestamp. End slot must always have a corresponding block produced, but if there is none for the start block, one should get the timestamp from the last produced block before such empty start slot. - -### Finding Unfillable Deposits -For the purpose of computing depositor refunds, each duplicate `Deposit` shall be considered unfillable by verifying that: -1. The `Deposit` is identical with another `Deposit`. -2. The destination chain `FillStatus` for the `Deposit` is `Filled`. -3. The destination chain `Fill` `FillType` was `SlowFill`. -4. The destination chain `Fill` occurred within the current `BundleBlockRange` or the `Deposit` occurred within the current `BundleBlockRange`. - -#### Note -- `Deposits` are considered identical when their `RelayData` matches. -- `Deposits` are considered duplicate when they are emitted after their initial identical instance. - -### Finding Slow Fill Requests -For the purpose of computing slow fills to be issued to recipients, each `Slow Fill Request` emitted within the `Bundle Block Range` on a destination SpokePool shall be considered valid by verifying that: -1. The `fillDeadline` is greater than `destinationChainId` bundle end block's `block.timestamp`, -2. The `Slow Fill Request` `RelayData` is matched by one or more corresponding `Deposit` events that occurred within or before the `Bundle Block Range` on the origin SpokePool, -3. The `inputToken` and `outputToken` addresses are equivalent at the earliest matching deposit's `quoteTimestamp`, -4. The destination SpokePool `FillStatus` mapping for the relevant `RelayData` hash is `SlowFillRequested` at the end of the `Bundle Block Range`, -5. The `originChainId` and `destinationChainId` are not Lite chains. - -#### Note -- A `Slow Fill Request` is made by supplying a complete copy of the relevant `RelayData` emitted by a `Deposit` event. -- The resulting set of validated `Slow Fill Requests` shall be included as SlowFills in the subsequent root bundle proposal. -- A `Slow Fill Request` may correspond to a `Deposit` from previous bundles. - -#### SVM support - -When evaluating if the `fillDeadline` / `fill_deadline` timestamp is greater than `destinationChainId` bundle end slot time, one can use `getBlock` RPC method for the destination chain's bundle end slot and use the `blockTime` field to compare against the `fillDeadline` / `fill_deadline` timestamp. - -### Finding Early Slow Fill Requests -When an early `Slow Fill Request` is implied, the `Slow Fill Request` shall be validated as follows: -1. The `fillDeadline` has not already elapsed relative to the `destinationChainId` bundle end block number, -2. The `inputToken` and `outputToken` addresses are equivalent at the earliest matching deposit's `quoteTimestamp`, -3. Neither the`originChainId` nor the `destinationChainId` is a `Lite` chain. - -#### Note -- An early `Slow Fill Request` is implied where a `Deposit` emitted within the current `Bundle Block Range` has a `FillStatus` of `SlowFillRequested` as at the end of the current `Bundle Block Range` on the destination chain, but where no `Slow Fill Request` is identified within the current `Bundle Block Range`. This may occur where the `Slow Fill Request` was submitted prior to the current bundle. - -### Computing LP Fees -Each valid `Fill` is subject to an LP fee. The procedure for computing LP fees is as defined in [UMIP-136 Add IS_RELAY_VALID as a supported price identifier](https://github.com/UMAprotocol/UMIPs/blob/7b1a046098d3e2583abd0372c5e9c6003b46ad92/UMIPs/umip-136.md), with the following amendments: -- The AcrossConfigStore contract shall be used to identify the correct rate model, instead of a `RateModelStore` contract. -- The `HubPool` `liquidityUtilizationCurrent()` and `liquidityUtilizationPostRelay()` functions shall be used instead of the `BridgePool` variant. -- The event `inputToken` shall be mapped from the SpokePool address to a HubPool `l1Token` address by following the matching procedure outlined above. -- The LP fee is computed between the `originChainId` specified by the `Deposit` and `repaymentChainId` specified by the relayer, where the `relayExecutionInfo.FillType != SlowFill` and the Fill `destinationChainId` otherwise. If the `originChainId` is equal to the `repaymentChainId` then the LP fee should be 0%. - -#### Note -- The LP fee is typically referenced as a multiplier of the `Deposit` `inputAmount`, named `realizedLpFeePct` elsewhere in this document. - -### Computing Bundle LP Fees -The bundle LP fee for a `Bundle Block Range` on a SpokePool and token pair shall be determined by summing the applicable LP fees for each of the following validated events: -- `FilledRelay`. -- `FilledV3Relay`. - -#### Note - -Each `FilledRelay` or `FilledV3Relay` can have multiple associated deposit events. In the event of multiple matching deposit events, there will be multiple LP fees paid per event in the case of a non slow fill. - -### Computing Relayer Repayments -For each validated matching `Deposit` event, the relayer repayment amount shall be computed as follows: -- `(inputAmount * (1 - realizedLpFeePct)) / 1e18`, where `realizedLpFeePct` is computed over the set of HubPool `l1Token`, `originChainId` and `repaymentChainId` at the HubPool block number corresponding to the relevant `Deposit` `quoteTimestamp`. -- The applicable rate model shall be sourced from the AcrossConfigStore contract for the relevant `l1Token`. -- For a given `Fill` that satisfies the requirements for relayer repayment, each matching `Deposit` generates a distinct repayment computed against its `quoteTimestamp`. - -The applied `repaymentToken` will be equal to the [equivalent](#resolving-spokepool-tokens-to-their-hubpool-equivalent) token as the `inputToken` on the `repaymentChainId`, where the applied `repaymentChainId` shall be determined as follows (all at the time of the relevant bundle's hub chain end block): -- When the `originChainId` is a `Lite chain`: `originChainId`, ELSE -- When no `PoolRebalanceRoute` exists for the `inputToken` on the `Fill` `originChainId`: `originChainId`, ELSE -- When no `PoolRebalanceRoute` exists for the `repaymentToken` on the `Fill` `repaymentChainId`: `originChainId`, ELSE -- The `repaymentChainId` as specified in the `Fill`. - -The applied `repayment address` shall be determined as follows: -- When the `Fill` `relayer` address is valid for the applied `repaymentChainId`: `relayer`, ELSE -- The `Fill` `msg.sender` address. In this case, change the applied `repaymentChainId` to the `destinationChainId` if a `PoolRebalanceRoute` exists for both the `outputToken` on the `destinationChainId` and the `inputToken` on the `originChainId` as at the bundle's hub chain end block - -If the applied `repayment address` is not valid for the applied `repaymentChainId`, the repayment shall be discarded from the relayer refund root but still considered when [computing running balances & net send amounts](#computing-running-balances--net-send-amounts). That way they could still be refunded manually by relaying a separate refund bundle via spoke pool admin function once the affected relayer provides a valid refund address on the applied `repaymentChainId` (precise mechanism is out of protocol scope, but that can be done by signing a message from the fill sender address). Examples of an invalid `relayer` address include: -- An SVM address on an EVM chain. -- An EVM address on an SVM chain. Even though in theory one might hold a corresponding private key, Across would not support refunding a relayer on a SVM chain to an address that has zeroes in its first 12 bytes. - -The rules above enforce that a `repaymentToken` for a successful relayer repayment is always equal to a token that is [equivalent](#resolving-spokepool-tokens-to-their-hubpool-equivalent) to the `inputToken` at the time of relevant bundle's hub chain end block. - -#### SVM support - -All the rules for computing relayer repayments as described in the generic [Computing Relayer Repayments](#computing-relayer-repayments) section above apply to SVM chains, except there is no `Fill` `msg.sender` address fallback logic when the `Fill` or resolved `repaymentChainId` is SVM chain. When the resolved `repaymentChainId` is SVM chain, the applied repayment token can be distributed to the associated token account derived from the `relayer` refund address. The relayer can also claim their refunds to any custom token account using the `Fill` `relayer` account as the signer. It is the responsibility of the relayer to ensure it passes the correct `Fill` `relayer` address that they control and that is valid for the resolved `repaymentChainId`. - -### Computing Deposit Refunds -For an expired `Deposit` event, the depositor refund amount shall be computed as `inputAmount` units of `inputToken`. - -### Computing Slow Fill updated output amounts -For the purpose of computing the amount to issue to a recipient for a SlowFill, the relayer fee shall be nulled by applying the following procedure: -- `updatedOutputAmount = (inputAmount * (1 - realizedLpFeePct)) / 1e18`, where `realizedLpFeePct` is computed at the earliest matching deposit's `quoteTimestamp` between `originChainId` and `destinationChainId`. - -#### Constraint -- The `Deposit` `outputAmount` shall _not_ be considered when determining SlowFill amounts. - -#### Note -- The `Deposit` `outputAmount` specifies the exact amount to be received by the `recipient` for a standard fill, and is therefore exclusive of any relayer or LP fees paid. - -### Finding the Opening Running Balance -The Opening Running Balance is defined as the cumulative running balance as at the previous successful (undisputed) Root Bundle Proposal. - -The Opening Running Balance for each unique `l1Token` and `repaymentChainId` pair shall be determined as follows: -1.

Add deposit refunds: - - For each group of `Deposit` events that expired or were deemed unfillable within the `Bundle Block Range`, sum the total deposit refunds on the origin chain. Add the amount to the exsting relayer refunds for that chain. - -4. Add slow fills: - - For each group of validated `Slow Fill Requests`, add each slow relay's `updatedOutputAmount` to the group's running balance. - -5. Subtract excesses from unexecuted slow fills: - - For each group of validated `Fills` where the `FillType` is `ReplacedSlowFill` and where there is no valid `Slow Fill Request` with an identical relay data hash in the current bundle data, subtract the SlowFill `updatedOutputAmount` from the running balance in recognition that the SlowFill will never be executed because the fill amount has already been transferred. - - For each expired deposit refund identified above where the `FillStatus` on the deposit destination chain is `RequestedSlowFill` and the matching slow fill request is not in the current bundle range, subtract the associated SlowFill `updatedOutputAmount` from the running balance in recognition that the SlowFill cannot be executed past the `fillDeadline`. - -6. Add the Opening Running Balance for the selected `l1Token` and `chainId` pair. - -8. Set the Net Send Amount and update the Running Balance for each `l1Token` and `chainId` pair subject to the outcome of `Computing Net Send Amounts` as described by the following algorithm: -``` -spoke_balance_threshold = the "threshold" value in `spokeTargetBalances` for this token -spoke_balance_target = the "target" value in `spokeTargetBalances` for this token - -net_send_amount = 0 -# If running balance is positive, then the hub owes the spoke funds. -if running_balance > 0: - net_send_amount = running_balance - running_balance = 0 -# If running balance is negative, withdraw enough from the spoke to the hub to return the running balance to its target -else if abs(running_balance) >= spoke_balance_threshold: - net_send_amount = min(running_balance + spoke_balance_target, 0) - running_balance = running_balance - net_send_amount -``` - -#### Note -The referenced `SpokeTargetBalances` is as specified by [UMIP-157 Token Constants](https://github.com/UMAprotocol/UMIPs/blob/pxrl/umip179/UMIPs/umip-157.md#token-constants): - -## Constructing Root Bundles - -### Constructing the Pool Rebalance Root -One Pool Rebalance Leaf shall be produced per unique `chainId` & `l1Token` pair, where the corresponding `Deposit`, `Fill` or`Slow Fill Request` events were emitted by the relevant SpokePool within the [Bundle Block Range](#identifying-bundle-block-ranges).

This will involve adding the currencies to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 400 USDC per request for USDC and 400 USDT per request for USDT. - -## Motivation -USDT and USDC are the world’s two largest stablecoins by market capitalization as well as traded volume. Both are widely used across the cryptocurrency space, especially on exchanges, where USDC and USDT based crypto-pairs account for a large share of trading volume. - -In comparison to DAI, which is already favored by many in the DeFi community because of its high level of decentralization, USDC and USDT are both fiat-backed stablecoins run by centralized organizations. With centralization comes risk, but the proven success of USDT and USDC, in terms of longevity and size, provide assurance about their ability to maintain value. - -USDC and USDT as collateral types are expected to have a variety of deployments. They will allow for the creation of USD based synthetic assets and will increase the general accessibilty of these assets, as the cryptocurrency market is accustomed to transacting in these currencies. - -## Technical Specification -To accomplish this upgrade, four changes need to be made: - -- The USDC address, 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48, needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 400 needs to be added for USDC in the Store contract. -- The USDT address, 0xdac17f958d2ee523a2206206994597c13d831ec7, needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 400 needs to be added for USDT in the Store contract. - -## Rationale -The rationale behind this change is giving deployers more useful collateral currency options. USDC and USDT are necessary, in addition to the already approved DAI, because of the size of the stablecoin market-share that they own. - -400 was chosen as the final fee for both USDC and USDT because this is practically equivalent to the final fee of already approved stablecoins. - -## Implementation - -This change has no implementation other than proposing the four aforementioned governor transactions that will be proposed. - -## Security considerations -Since USDC and USDT are persistently valuable ERC20 tokens, including both as supported collateral currencies should impose no additional risk to the protocol. - -The main implication is for contract deployers and users who are considering using contracts with USDC or USDT as the collateral currency. They should recognize and accept the centralization risk of using USDC or USDT, as both are fiat-backed or cash-equivalent backed stablecoins run by centralized organizations. USDC is issued and backed by Coinbase and Circle Invest, while USDT is issued and backed by Tether Limited. - -USDT is a non-standard ERC20 as the USDT approve function does not comply with the ERC20 standard. This should not have any immediate security implications, as UMA Protocol contracts use OpenZeppelin's [SafeERC20 wrapper](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/SafeERC20.sol), but should be noted as it *could* have implementation consequences for some financial contracts. - -New price identifiers, that are intended to be used with these collateral currencies, will need to be specified to 6 decimals of precision in order to comply with USDC and USDT. \ No newline at end of file diff --git a/research/uma/umips/umip-180.md b/research/uma/umips/umip-180.md deleted file mode 100644 index 7559c8fd..00000000 --- a/research/uma/umips/umip-180.md +++ /dev/null @@ -1,33 +0,0 @@ -## Headers - -| UMIP-180 | | -| ---------- | ----------------------------------------------------------- | -| UMIP Title | Register Base Parent Messenger in OracleHub and GovernorHub | -| Authors | Pablo Maldonado | -| Status | Approved | -| Created | 03/28/24 | - -## Summary - -This UMIP proposes to register the [Base Parent Messenger](https://etherscan.io/address/0x721bA6f9A0a44657f008f3d68C6dBdDeDBDE831A) with both the [Oracle Hub](https://etherscan.io/address/0x8fE658AeB8d55fd1F3E157Ff8B316E232ffFF372) and [Governor Hub](https://etherscan.io/address/0x94520d90A4EBaA98e5A7B8D6809463f65198C104) to facilitate cross-chain communication and ensure the operational functionality of newly deployed Base contracts, including the Optimistic Oracle. Additionally, it aims to reduce the default gas limit for transactions on both Optimism and Base Parent Messengers from 5 million to 500,000, thus optimizing network efficiency by correcting previously excessive gas allocations. - -## Motivation - -The registration of the Base Parent Messenger with the Oracle and Governor Hubs is critical for enabling cross-chain communications, essential for the operation of Optimistic Oracles and governance processes on Base EVM-compatible network.

The request should define the event, how to evaluate values for the event, and labels for all values requested. The oracle will return the values encoded into a single `int256` price that can be decoded by the integrating smart contract. The [oracle UI](https://oracle.uma.xyz) will handle all encoding and decoding for users and only display human readable values. - -# Motivation -Currently sports betting platforms are making binary requests for multiple markets that are all settled based on the scores from a single sports game. This is unnecessary and costly. This UMIP will allow the OO to report the scores of two sports teams in one encoded price. Then integrators can decode the scores from the price and evaluate the scores to settle multiple markets. Sports games are the initial motivation for this UMIP, but it is generalizable to any request for multiple integer values from a single event. - -# Data Specifications - -It is not possible to define specific data sources for this identifier.

The values should be encoded into a `int256` response as per the following: - -- The values should ordered as per the indexing from label array included in the decoded ancillary data and encoded as such: - ```ts - Int256 - | 32 bits | 32 bits | 32 bits |... | 32 bits | - | unused | value6 | value5 |... | value0 | - | 224-255 | 192-223 | 160-191 |... | 0-31 | - ``` - -For each label provided in the `labels` array, its corresponding value (if present) is encoded into the following bit ranges: -- The **first label** (`labels[0]`) corresponds to the first 32 bits (bits 0–31). -- The **second label** (`labels[1]`) corresponds to the next 32 bits (bits 32–63). -- This pattern continues up to the **seventh label** (`labels[6]`), which corresponds to bits 192–223. - -If there are fewer than 7 labels provided, the values should be encoded starting with the least significant positions, leaving the most significant positions unused. The unused positions must be set to zero. Any non-zero values present in these unused positions will render the price invalid. The most significant 32 bits are always unused to prevent collisions with the other valid responses below. - -Other valid price responses are: -- **No answer possible**: Voters should resolve the request to `57896044618658097711785492504343953926634992332820282019728792003956564819967` or `type(int256).max` if any of the following conditions are met: - - The event cannot be resolved (e.g., it was canceled). - - The price cannot be encoded as specified (e.g., more than 7 labels, any value exceeds 32 bits). - - The ancillary data is invalid JSON or does not match the specified TypeScript schema.

Details on our current emissions: - -- Emissions Rate: 0.18 UMA per second (5,676,480 UMA per annum) (source: Etherscan) -- Circulating Supply: 84,605,309 UMA (source: CoinGecko) -- Current Inflation Rate: 6.7% -- Cumulative Stake: 21.6M UMA -- Current APY: ~26% -- 30 Day Average Voters (Dec 2024): 280 -- 30 Day Average Voting Power (Dec 2024): 18.4M UMA -- Participation Rate (Dec 2024): 22% (Voting Power / Circulating Supply) -There are several reasons why we think the UMA DAO should reduce emissions: -1. Potential Overpayment: Our current emissions may be higher than necessary to maintain our current staking and voter base. -2. Staker/ Voter Inelasticity: We believe the voting base is relatively inelastic and will likely remain stable even with reduced rates. UMA voters will still earn handsome rewards for their participation in the voting process even if current rates were to half. -3. Reduced sell pressure: Reducing excess UMA supply hitting the market could positively impact the value of the underlying asset. - -## Specification & Implementation - -We propose lowering the emission rate over 3 separate cuts of 0.025 UMA per second, each signed off by individual votes and followed by analysis periods. The terminal emissions rate should not be lower than 0.105 UMA per second (~15% APR). - -This first proposal will involve the following: -1. Cut: reduce emissions by 14% (0.18 UMA/s to 0.155 UMA/s)[~26.3% APR to 22.6% APR] -2. Analysis: assess impact on staking / voting base -- Safeguard: Revert cut and pause further reductions if the 7 day moving average of voters who reveal falls by >20% of the 30 day moving average of the same metric on the day the vote passes. -- Subsequent cuts: Additional 0.025 UMA per second reduction votes if analysis suggests the voting base has not decreased significantly. - -These votes should occur every 2 months until the terminal emissions rate is reached or the safeguard measure comes into effect. - -The recurring proposals should follow this flow: -1. Reporting is posted on discourse for information and discussion with community -2. Snapshot vote starts three days after the above is posted. If passed, move to DVM with bonds sponsored by RL as outlined in the governance docs. -3. DVM vote executes the setEmissionRate function on the VotingV2 contract through UMA DAO’s GovernorV2 contract. - -## Goals - -1. Find the optimal emissions rate that balances rewards and participation -2. Reduce inflation while maintaining a healthy staking ecosystem -3. Improve overall token economics for UMA - -## Potential Downside -If the staking / voting base is more elastic than anticipated this could lead to a reduction in the economic security provided by the Optimistic Oracle as some voters unstake. There is a possibility that these persons exit from the UMA system and do not return. APYs should increase to make it more attractive for new stakers / voters to come in and replace these persons if this occurs. We also have our analysis safeguard in place to revert cuts if the staking base reaction is outsized. - -## Voting - -- A yes vote means that you would like to decrease the emissions rate from 0.18 UMA/s to 0.155 UMA/s. -- A no vote means that you would like to keep the emissions rate at 0.18 UMA/s - -DVM vote to follow if Snapshot vote is successful. diff --git a/research/uma/umips/umip-185.md b/research/uma/umips/umip-185.md deleted file mode 100644 index d25597ae..00000000 --- a/research/uma/umips/umip-185.md +++ /dev/null @@ -1,88 +0,0 @@ -## Headers - -| UMIP-185 | | -| -------------- | ------------------------------------------------------------------------------------------------------ | -| UMIP Title | Upgrade Oracle Request Bridging Contracts | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Approved | -| Created | April 2, 2024 | -| Discourse Link | [UMA's Discourse](https://discourse.uma.xyz/t/umip-185-upgrade-oracle-request-bridging-contracts/2178) | - -## Summary - -This UMIP proposes to register the upgraded `OracleRootTunnel` and `OracleChildTunnel` contracts for the Polygon network, as well as the upgraded `OracleSpoke` contracts on all the supported optimistic rollup networks. - -## Motivation - -This upgrade is focused on compressing ancillary data as Oracle requests are bridged to Ethereum mainnet, reducing the gas costs for the relayer bots and voting users.

-## Rationale - -The changes introduced in the upgraded `OracleSpoke` and `OracleChildTunnel` contracts are quite similar, so there might be an argument for using the same codebase for optimistic rollup networks and Polygon. Even if migrating Polygon contracts to use hub and spoke model is technically feasible, it is considered to add additional complexity and potential risks to the migration process, hence it is proposed to keep both bridging systems separate. - -During the development process it was also considered to compress the ancillary data only when it exceeds certain threshold, so that the compressed version (including the additional metadata) never exceeds the original ancillary data size. Even if this would have saved some gas costs, it was decided to always use the same ancillary data format to simplify the implementation. Also, based on Q1 2025 data, this would have reduced the gas costs further only in ~2.5% of the cases. - -## Implementation - -When using the upgraded contracts, the ancillary data for bridged Oracle requests will include the following fields: - -- `ancillaryDataHash` - the `keccak256` hash of the original ancillary data -- `childBlockNumber` - the block number on the child network when the Oracle request was originated -- `childOracle` - the address of the bridging contract on the child network (either `OracleChildTunnel` or `OracleSpoke`) -- `childRequester` - the address of the Oracle requester on the child network -- `childChainId` - the chain ID of the child network where the Oracle request was originated - -When observing the `RequestAdded` events on the Ethereum mainnet `VotingV2` contract, if the indexed `requester` field is either the `OracleRootTunnel` or `OracleHub` contract and the `ancillaryData` has above specified fields, the original ancillary data will need to be resolved using the following steps: - -1. Calculate the parent request ID by `keccak256` hashing the ABI encoded `bytes32 identifier`, `uint256 time` and `bytes ancillaryData` from the `RequestAdded` event. -2. Query the `OracleChildTunnel` or `OracleSpoke` contracts (using `childOracle` address) on the child network (referenced by `childChainId`) for the `PriceRequestBridged` event filtering it for the indexed `parentRequestId` field as calculated in the previous step. This log query can be further optimized by limiting the search to the block range from and to the `childBlockNumber` value. -3. Inspect the `ancillaryData` field from the matched `PriceRequestBridged` event from the previous step to obtain the original ancillary data. - -## Security Considerations - -When upgrading smart contracts, it is important to ensure that the new implementation is secure and the migration process is executed correctly. The proposed contract changes have been reviewed by the UMA team and audited by OpenZeppelin. In addition, OpenZeppelin has reviewed the proposed migration payload and UMA team has simulated its execution on the forked networks. - -Following the upgrade, special attention should be taken to all unsettled disputes that were originated before the upgrade and used the old contracts when bridging the requests to Ethereum mainnet. Both `OracleSpoke` and `OracleChildTunnel` contracts have a dedicated `resolveLegacyRequest` function that will be used resolve these disputes after the upgrade. diff --git a/research/uma/umips/umip-186.md b/research/uma/umips/umip-186.md deleted file mode 100644 index a5bfb747..00000000 --- a/research/uma/umips/umip-186.md +++ /dev/null @@ -1,47 +0,0 @@ -| UMIP-186 | | -| ---------- | --------------------------------------------------------------------------------------------------------------------- | -| UMIP Title | Increase SPAT to 65% in VotingV2 Contract | -| Authors | Lee Poettcker | -| Created | April 10, 2025 | -| Discussion | [Discourse](https://discourse.uma.xyz/t/increase-spat-to-65/2177) | - -### Summary -This proposal modifies the Settlement Price Approval Threshold (SPAT) parameter within UMA's VotingV2 contract from 50% to 65%. SPAT is the percentage of staked UMA that needs to agree for a dispute resolution vote to pass. Raising the SPAT means that voters must come to a strong consensus to settle a dispute. Analysis of 2025 voting data shows only 6/291 requests (2%) would have been affected by this change. - -### Background -The Data Verification Mechanism (DVM) currently requires the majority vote to reach a SPAT which is calculated as the majority token weighted vote divided by all staked UMA. If the SPAT is met the dispute is resolved to the majority vote. If the SPAT is not met, the vote “rolls” to the next voting round to be tried again. This continues until the dispute is resolved or the vote rolls 5 times and is subsequently deleted without being resolved. - -### Motivation -The DVM is designed for voters converge on an unambiguous Schelling point. However, the current 50% SPAT allows disputes to resolve where nearly half of participants disagree - a condition that risks enforcing weakly supported outcomes during contentious votes. - -By raising the SPAT, weak majority votes will roll which allows additional time for voters to reconsider their position, UMA community discussion, and requesters can optionally choose to clarify their request. This additional time should help subsequent votes towards a stronger majority that better reflects the Schelling point and is a more reliable dispute resolution. - -This change does increase the risk that votes will roll 5 times and go unresolved which is undesirable. However, this puts pressure on requesters to ensure their requests can be resolved to a strong Schelling point via the original rules or clarifications. - -### Technical Specification -To make the proposed change, the UMA [GovernorV2](https://etherscan.io/address/0x7b292034084a41b9d441b71b6e3557edd0463fa8) contract should call the [VotingV2](https://etherscan.io/address/0x004395edb43efca9885cedad51ec9faf93bd34ac) contract’s [setGatAndSpat](https://etherscan.io/address/0x004395edb43efca9885cedad51ec9faf93bd34ac#writeProxyContract#F19) function with the following arguments: -GAT: 5M UMA (note: unchanged) -SPAT: 65% - -### Rationale -The new SPAT value of 65% was chosen to increase the minimum consensus needed while being below the minimum voter participation and keeping rolled votes relatively infrequent to not overburden voters. - -The voting participation rate in 2025 has averaged 92% with a minimum of 67%. Below is a histogram showing the occurrence of votes by the majority vote share over the last 12 months. As a point of reference, there have been 11 votes with less than 65% majority vote share in 2025. - -***Note: see [Discourse post](https://discourse.uma.xyz/t/increase-spat-to-65/2177) to view histogram.** - -Over the last year, there have been 14 rolled votes. The average majority vote share was 45%. In the second round, 13 of these votes passed and the average majority vote share was 77%. The one remaining vote passed in the third round with a majority vote share of 59%. This shows that as votes get re-rolled UMA voters do typically converge to a stronger consensus. - -A historical analysis of majority vote percentages was performed. A SPAT of 65% was chosen to limit the number of rolled votes and be below the lowest vote participation rates. - -### Security Considerations -This proposal requires no code changes, only a parameter update. Raising the SPAT will also increase the cost of corrupting the DVM as any attack will now require 66% of staked UMA instead of 51%. - -### Risks -A higher SPAT will lead to more rolled votes and therefore more votes. However, as shown in the data above this is expected to be minimal. -Requests that roll will have a longer time to resolution. -Persistently contentious requests that can’t make a >65% majority vote within 5 rolls will be deleted and go unresolved. - -### Implementation -1.

This recent downward trend is not seen in the voting power graph which suggests the voter decline is likely due to small voters leaving after the gas rebate change which required a minimum stake of 500 UMA to be eligible for gas rebates. This change took effect on February 1st, but the first rebate under the new requirements was not paid out until March 13th. So many small voters may not have been aware of the change until mid March. - -A better measure of the effect of the UMA Emission Reduction is to look at the number of addresses voting with over 500 UMA (see chart at Discourse link above). This removes the effect of the gas rebate minimum and only takes into account addresses that have enough stake to meaningfully contribute to UMA’s staking decentralization. Below is a chart of voters with over 500 UMA staked: - -Based on the above data we recommend continuing with the UMA emission plans as laid out in the original proposal. - -## Voting -A yes vote means that you would like to decrease the emissions rate from 0.155 UMA/s to 0.130 UMA/s.

This allows the integration to have easier access to functionality already present in OptimisticOracleV2 without diminishing the role of UMA governance over the new contract. If passed, this UMIP will approve a ManagedOptimisticOracleV2 managed by Polymarket to send disputes to UMA’s Data Verification Mechanism (DVM) for UMA stakers to resolve. - -## Motivation -The current OptimisticOracleV2 contract allows integrations to revise a request’s bond amount, liveness, and who can propose, but requires these changes to be made through the integration’s requesting contract. This requirement has made it more difficult for integrations to manage their requests as easily as they would like. - -The new ManagedOptimisticOracleV2 contract is designed to be used by a single integration and gives the integrator admin access to easily modify the bond, liveness, and who can propose for all of their requests. - -## Technical Specification -All new oracle deployments must be given permission by the UMA DAO to send their disputes to the DVM for resolution.

A summary of the changes from OptimisticOracleV2 is given below. - -The ManagedOptimisticOracleV2 is intended to only serve a single integration. The integrator can more easily access functionality that is already supported in OptimisticOracleV2 via two new roles: -- **owner**: a high security address that can: - - add and remove request managers - - set the default proposer whitelist which applies all new requests - - set the requester whitelist which controls who can make requests - - set the minimum liveness and minimum / maximum bond that the request manager can set a request to - -- **requestManager**: address used more frequently to: - - revise an unproposed request’s bond size, liveness and set the proposer whitelist - -The newly deployed ManagedOptimistOracleV2 contract to be approved by this UMIP will be upgradable via a 2/2 multisig consisting of Polymarket and Risk Labs. - -UMA DAO governance will still have all the same parameter controls it has over the standard OptimisticOracleV2 contract, such as approving new bond collaterals and price identifiers, and setting final fees for a given bond collateral. - -## Security Considerations -ManagedOptimisticOracleV2 includes minor changes to the long running and previously audited OptimisticOracleV2 contract. ManagedOptimisticOracleV2 is undergoing an internal audit that will be completed before this UMIP proceeds to an onchain vote with an OpenZeppelin audit to follow ASAP. If this UMIP passes, this contract should only be used for low risk use cases until the OpenZeppelin audit has been completed. - -## Voting -**YES**: approve the ManagedOptimisticOracleV2 at `0x2C0367a9DB231dDeBd88a94b4f6461a6e47C58B1` managed by Polymarket to send disputes to the DVM. -**NO**: do NOT approve the ManagedOptimisticOracleV2 at `0x2C0367a9DB231dDeBd88a94b4f6461a6e47C58B1` managed by Polymarket to send disputes to the DVM. diff --git a/research/uma/umips/umip-19.md b/research/uma/umips/umip-19.md deleted file mode 100644 index 8d636fe0..00000000 --- a/research/uma/umips/umip-19.md +++ /dev/null @@ -1,72 +0,0 @@ -## Headers -| UMIP-19 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add ARSUSD as a price identifier | -| Authors | Sean Brown (sean@umaproject.org) | -| Status | Approved | -| Created | October 28, 2020 | - -## Summary (2-5 sentences) -The DVM should support price requests for the ARS/USD price index. - - -## Motivation -The DVM currently does not support the ARS/USD price index. - -Supporting the ARSUSD price identifier would enable the creation of an Argentine Peso stablecoin, backed by USD. Token minters could go short on the ARS/USD index, while token holders could go long or use synthetic ARS for functional purposes. - -One practical use for synthetic ARS is in trading pairs on Argentinian cryptocurrency exchanges. - -There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available. - -## Technical Specification -The definition of this identifier should be: - -- Identifier name: ARSUSD -- Base Currency: ARS -- Quote Currency: USD -- Data Sources: Ripio, SatoshiTango, CoinMonitor -- Result Processing: Median. BTC/ARS to ARS/USD conversion defined in the implementation section. -- Input Processing: Human intervention in extreme circumstances where the result differs from broad market consensus. -- Price Steps: 0.000001 (6 decimals in more general trading format) -- Rounding: Closest, 0.5 up -- Pricing Interval: 300 seconds -- Dispute timestamp rounding: down -- Scaling Decimals: 18 (1e18) - -## Rationale -Prices are primarily used by Priceless contracts to calculate a synthetic token’s redemptive value in case of liquidation or expiration. Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. - -ARSUSD uses Ripio, SatoshiTango and CoinMonitor for BTCARS price information. Ripio and SatoshiTango are Argentinian cryptocurrency exchanges and were chosen because they have some of the highest genuine volumes of ARS/BTC trading. CoinMonitor is a price aggregator that determines its ARS/BTC price as a result of taking the median of a group of buy and a group of sell prices from various cryptocurrency exchanges and then averaging the two. CoinMonitor was chosen as a data source because its price calculation methodology creates a good representation of what the true market rate for BTC/ARS is. All three sources offer free and publicly accessible historical BTC/ARS endpoints. - -The decision, to query for BTC/ARS and BTC/USD instead of directly querying for ARS/USD, was made because the ARS/USD pair has a large variance in price reporting, caused by artificial factors. Products built with the ARSUSD price identifier are most likely to be used in Argentinian cryptocurrency exchanges, so the price identifier should use the price reflected by the highest volume crypto-native ARS trading pair. - -More explicitly, the choice to use BTC/ARS over ARS/USD has to do with the fact that Argentina is currently under a capital restrictions scheme, where retail users and companies cannot access the official exchange rate to buy goods or services. Because of this situation, there are several USD/ARS rates currently within a ~100% spread between the official and unofficial rate. Since this rate will be used to create crypto assets, we consider the fair USD/ARS exchange rate to be the one which you can access to purchase cryptocurrencies. BTC/ARS is the pair with the majority of the trading in the country, with an estimate of 80% of the total volume, with more than 10 different brokers operating daily in the country. Correctly assessing the USD/ARS exchange rate is a complex task and probably will be even more complex in the near future. Since synthetic ARS by nature would be used in cryptocurrency transactions, the argument is that the best approach would be to have the value of synthetic ARS track the rate that a crypto user would get by exchanging ARS into BTC and then BTC into USDC (or an equivalent). - -## Implementation - -The value of ARSUSD for a given timestamp can be determined with the following process. - -1. BTC/ARS should be queried for from the endpoints below for the given timestamp rounded to the nearest available endpoint time value. The results of these queries should be kept at the level of precision they are returned at. -2. The median of the BTC/ARS results should then be taken. -3. The inverse of the BTC/ARS mean is then taken (1/BTCARS) to determine ARS/BTC. -4. The value of BTC/USD for the same timestamp will then need to be determined by following the implementation guidelines defined in UMIP-7. -5.

However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. \ No newline at end of file diff --git a/research/uma/umips/umip-190.md b/research/uma/umips/umip-190.md deleted file mode 100644 index 2b325b94..00000000 --- a/research/uma/umips/umip-190.md +++ /dev/null @@ -1,503 +0,0 @@ -## Headers - -| UMIP-190 | | -| ------------------- | --------------------------------------------------------------- | -| **UMIP Title** | Currency Whitelist Maintenance and Fee Updates | -| **Authors** | UMA Protocol Team | -| **Status** | Draft | -| **Created** | August 28, 2025 | - ---- - -## Summary - -This UMIP proposes whitelist housekeeping across Ethereum mainnet, Polygon, Arbitrum, Optimism, Base, and Blast: - -- **Remove** a defined set of deprecated currency addresses from each network’s whitelist. -- **Reset final fees to 0** for removed currencies. -- **Update final fees** for WETH on all supported chains, and for ABT on mainnet. -- **Retire Boba messenger support** (chainId **288**) on mainnet. - -To keep on-chain proposals small and auditable, these changes are executed via **four separate proposals** (Parts 1–4). The canonical action lists are included below. - ---- - -## Motivation - -Over time, UMA’s currency whitelists accumulate assets that are no longer actively used. Periodic housekeeping removes inactive entries and simplifies operations. This UMIP performs: - -- **Whitelist pruning** of currencies that are not actively used on mainnet, Polygon, Arbitrum, Optimism, Base, and Blast. **Note: these currencies could be re-whitelisted in the future if use cases arise.** -- **Fee table alignment** for actively used currencies (WETH, USDC, ABT). -- **Removal of Boba chain support** by retiring the Boba messenger. - -No protocol semantics change and no new functionality is introduced—this is a standard clean-up and parameter alignment exercise. - ---- - -## Technical Specification - -All actions are executed through the standard UMA Governor process on each network. - -### Common operations - -- **Remove currency from whitelist:** - `removeFromWhitelist(address collateral)` -- **Set/Reset final fee:** - `setFinalFee(address currency, FixedPoint.Unsigned memory newFinalFee)` - (For removed currencies, `newFee = 0`.) -- **Retire messenger (mainnet):** - Remove Boba **chainId 288** from supported

Martinsons (reinis@umaproject.org) | -| Status | Draft | -| Created | November 28, 2025 | -| Discourse Link | https://discourse.uma.xyz/t/feat-umip-191-whitelist-assert-truth2/2244 | - -# Summary - -The DVM should support price requests for the `ASSERT_TRUTH2` price identifier. `ASSERT_TRUTH2` is intended to work the - same as `ASSERT_TRUTH` which was whitelisted as part of [UMIP-170](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-170.md). - -This UMIP allows asserters to make claims about the state of the world. It does not attempt to put any restrictions on - the types of claims that can be made, but rather focuses on the mechanics of how the DVM should be used to resolve - disputes over such claims. - -Price settlement can happen only in one of two ways: - -- Return the `1` value if the claim is true and publicly verifiable. -- Return the `0` value if the claim is false or cannot be resolved. - -# Motivation - -This price identifier is intended as a one for one replacement of the retired `ASSERT_TRUTH` price identifier. It will - allow integrating partners to build their products on top of UMA's Optimistic Oracle V3 contract. This will allow their - users to make claims about the state of the world and resolve disputes over these claims in a trustless manner. - -# Data Specifications - -It is not possible to define specific data sources or markets for this identifier. Determination of data sources and - results are left entirely up to potential disputers and voters as the best method of determining the results will - depend on the claim being made. - -# Price Feed Implementation - -No price feed is needed (or possible) for this price identifier. - -# Technical Specifications - -- Price identifier name: ASSERT_TRUTH2 -- Base Currency: NA -- Quote Currency: NA -- Rounding: None, there is a predetermined set of results. -- Estimated current value of price identifier: NA - -## Ancillary Data Specifications - -Upon dispute the following ancillary data parameters will be available to the voter after converting it from bytes to - UTF-8: - -- `assertionId`: The ID of the assertion being disputed. -- `ooAsserter`: The address of the asserter that made the claim. - -If the assertion was disputed on any other chain than Ethereum mainnet, the original ancillary data has to be resolved - first from `PriceRequestBridged` event emitted on the child chain using the procedure as outlined in [UMIP-185](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-185.md). - -# Rationale - -This construction sacrifices assurances of determinism in favor of greater price identifier flexibility. This places the - burden of correct construction on claims being asserted, but, in return, allows for quicker and easier development - without needing to pass through UMA governance for each additional application that builds on top of Optimistic - Oracle V3 contract. - -# Implementation - -1. Voters should identify the Optimistic Oracle V3 contract that was used to make and dispute the assertion. This can be - done by calling `getImplementationAddress` on the `Finder` contract with the `OptimisticOracleV3` identifier encoded as - `bytes32` at the time of DVM request. The address of the `Finder` contract depends on the network where the dispute was - raised and is available in the `networks` directory of the UMA [protocol repository](https://github.com/UMAprotocol/protocol/tree/master/packages/core/networks). -2. Voters should decode the ancillary data of the request and determine its `assertionId` parameter. -3. Voters should search the `AssertionMade` event emitted by the Optimistic Oracle V3 contract from Step 1 for an - assertion with the matching `assertionId` parameter from Step 2. Take a note of the timestamp of this event and its - `claim` parameter, as well as any other relevant fields needed to resolve the dispute. -4. Voters should attempt to decode the `claim` parameter from Step 3 as UTF-8 string. If the decoding fails, the claim - is not a string that can be asserted truthful, and voters should return the `0` value. -5. The decoded `claim` string from Step 4 could include references to the timestamp that was used to make the assertion. - If not present, voters should assume that the timestamp of the `AssertionMade` event from Step 3 should be used. -6. Voters should attempt to evaluate whether the decoded `claim` from Step 4 represents the true state of the world as - of claim's timestamp determined from Step 5: - - If the claim was true, voters should return the `1` value. - - If the claim was false, voters should return the `0` value. - - If the claim cannot be unambiguously resolved, voters should return the `0` value. - -All resolved price values should be scaled by `1e18` when interacting with contracts directly (e.g. writing scripts, - console access or interacting through block explorer). Optimistic Oracle and Voting dApps scale price response - automatically or can abstract the price value with simple `YES` or `NO` answer to the truthfulness of the claim for - the convenience of the voter. - -# Security Considerations - -This construction sacrifices assurances of determinism in favor of greater price identifier flexibility. Users of this - price identifier should be careful to ensure that claims being made through Optimistic Oracle V3 contract can be - evaluated to reach a deterministic outcome. - -In case of any future upgrades to the Optimistic Oracle V3 contract the Step 1 in the Implementation section should also - be updated since its instructions currently assume only one version of the Optimistic Oracle V3 contract is deployed - per supported network. - diff --git a/research/uma/umips/umip-192.md b/research/uma/umips/umip-192.md deleted file mode 100644 index 795b2e18..00000000 --- a/research/uma/umips/umip-192.md +++ /dev/null @@ -1,68 +0,0 @@ -## Headers - -| UMIP-192 | | -| -------------- | ----------------------------------------------------------------------------------------- | -| UMIP Title | Retire `ASSERT_TRUTH` as a supported price identifier | -| Authors | Reinis Martinsons (reinis@umaproject.org) | -| Status | Draft | -| Created | November 28, 2025 | -| Discourse Link | https://discourse.uma.xyz/t/feat-retire-assert-truth-as-a-supported-price-identifier/2245 | - -## Summary - -This proposal removes the whitelisted `ASSERT_TRUTH` price identifier (see [UMIP-170](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-170.md)) - used as the default price identifier for `OptimisticOracleV3` (OOV3).

Calculating, for example, Bitcoin dominance involves knowing the current supply of bitcoin, the prevailing market price of BTC/USD, and the total market capitalization of all tokens in USD. More importantly, calculating the total market capitalization of all tokens in USD is a challenge since different data sources may altogether not include particular alt-coins thereby affecting all coin market dominance percentages. - -At the moment, Bitcoin dominance is commonly referenced through three major sources: TradingView, CoinMarketCap & CoinGecko. However, unlike trading pairs which exhibit strong redundancy without deviation largely due to arbitrage incentives, each data source can vary by multiple percentage points due to differing calculation methodologies. Namely, each site has different methodologies for which alt-coins to admit into the total market cap, and a given coin’s market price and total coin circulation amounts may differ, compounding over hundreds or even thousands of alt-coins. Additionally, on a technical note, live and historical data update frequency varies and historical data may be paywalled, making it significantly harder to successfully run liquidation and dispute bots with redundancy and without paying for API access. To make matters worse, had we proposed a scheme where multiple data sources were used, we’d have to decide on using either the median or mean of the data sources and then have to specify some logic to handle if one of the data sources went down or starting to significantly different from the rest, for example. - -In an effort to alleviate these challenges, the Domination Finance team was able to get in touch with Bobby & TM, the cofounders of CoinGecko. The CoinGecko team went above and beyond to meet the requisites, updating CoinGecko’s coin dominance live data to 1-3 minute intervals from what was previously 10 minutes. Although this may introduce a single point of failure, we felt that the costs in increased complexity and mental load on the stakeholders who need to use it (like speculators, sponsors, liquidators & disputers) outweighed the benefits, especially during this period where the synthetic token is newly launched. - -While CoinGecko was able to provide the higher time granularity for coin dominance on short notice, historical data, necessary for dispute bots and voters, was unable to be immediately supplied from CoinGecko. Instead, constructing a separate caching service is necessary to track and record the historical data from polling the CoinGecko live API to be able to compute historical coin dominance at a given point in time. This stop gap measure should be more than sufficient to provide the historical data for dispute bots and voters.

The synthetic token address will be listed in the Technical Specification section. - -## Motivation -The motivation for calculating aggregatory Ethereum gas prices in a set amount of units of gas is explained in [UMIP-16](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-16.md) and [UMIP-20](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-20.md). - -For the creation of a tokenized gas price futures contract, it is desired that the DVM return either the monthly median gas price for 1 million units of gas, or a 2-hour TWAP on the market price of uGAS. The type of price that the DVM will return is dependent on the timestamp the price request is made at. This timestamp is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the median monthly gas price calculation is used at expiry. - -This pricing structure will allow for the creation of a tokenized futures contract that is collateralized at the **expected** price for the median monthly gas price settlement, rather than the actual median monthly gas price. This is important because the market price of a futures contract is based upon the expectation of the underlying price movement, rather than the current underlying price. Token minters should not be able to collateralize positions at a different price compared to the market price that they could sell the tokens for. This could lead to intentional and frequent under-collateralization, but is remedied by using the token’s market TWAP as the collateralization reference. - -## Technical Specification - -The definition of this identifier should be: -- Identifier name: GASETH-TWAP-1Mx1M -- Base Currency: uGAS -- Quote Currency: ETH -- Sources: any Ethereum full node or data set of Ethereum node data. uGAS/ETH Uniswap pool price events. -- Result Processing: multiply by a million when calculating aggregatory gas prices. -- Input Processing: See the UMIP-16 Implementation Section.

This choice was made because a synthetic token, that is trading based on the future price of an underlying index, will have its price affected by expectations of the future movement of the underlying. If there is a large discrepancy in the synthetic’s price and the underlying index, arbitrageurs could take advantage of the difference in price by minting tokens at a rate determined by the underlying, abandoning their collateral to be liquidated and selling the tokens at the higher trading rate. Additionally, if a token is trading at a price that is higher than the notional value of the backing collateral, there would be no economic incentive for a liquidator to perform a liquidation. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -## Implementation - -If the price request's UTC timestamp is less than `1625097600`, voters will need to calculate a 2-hour TWAP for the uGAS token's price in ETH. The following process should be used to calculate the TWAP. - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the ETH/uGAS pool returns at the end of the latest block whose timestamp is <= the timestamp that is queried for. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. As the token price will already implicitly be tracking the GASETH-1M-1M price, it should be left as returned without any scaling transformation. -6. The final price should be returned with the synthetic token as the denominator of the price pair and should be submitted with 18 decimals. - -If the price request's UTC timestamp is at or after `1625097600`, a price request for GASETH-TWAP-1Mx1M will follow the calculation methodology for the GASETH-1M-1M identifier defined in the UMIP-20 Rationale and Implementation sections. - -For both implementations, voters should determine whether the returned price differs from broad market consensus.

This feed should be used as a convenient way to query a realtime or historical price, but voters are encouraged to build their own off-chain price feeds. - -## Security considerations - -Security considerations pertaining to calculating an aggregate gas price are covered in the Security Considerations section of [UMIP-16](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-16.md). - -There are two general security considerations for using a token price for collateralization. - -1. **Token price manipulation** - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradeable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -2. **Mismatch between TWAP and gap higher in token price** - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations - as the 30-day median gas price should be slow moving by design - or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uGAS, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -This is the first DVM supported price identifier of its kind, so synthetic token holders should proceed with caution when interacting with a contract using this identifier.

Token minters could go short on the BCHN/BTC index, while token holders could go long or use synthetic BCHN for functional purposes. - -Due to the recent hard fork last week, there has been a divergence in the sha256 miners for BCH between supporting the A or N chains. Currently, BCHN is disproportionately winning, and there is no containerized way to allocate risk to taking a view on BCH natively in the Ethereum DeFi ecosystem aside from the iBCH synthetic on Synthetix, which we believe is unideal for BTC denominated entities looking to take a view on the BCHN/BTC spread. Further, given the large interest in iBCH, relative to the other i* synthetics on Synthetix, there exists empirical evidence that there is strong retail demand in the eth defi community to express short interest on BCH. Lastly, given the current regime, empirically retail has viewed BCH as levered beta on BTC which will fuel the longs for this synthetic minting. - -There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available. - -## Technical Specification -The definition of this identifier should be: - -- Identifier name: BCHNBTC -- Base Currency: BCHN -- Quote Currency: BTC -- Data Sources: Binance, Coinbase Pro, Huobi -- Result Processing: Median of BCH/BTC -- Input Processing: None. Human intervention in extreme circumstances where the result differs from broad market consensus. -- Decimals: 8 -- Rounding: Closest, 0.5 up -- Pricing Interval: 60 seconds -- Dispute timestamp rounding: down -- Scaling Decimals: 8 (1e8) - -## Rationale -Prices are primarily used by Priceless contracts to calculate a synthetic token’s redemptive value in case of liquidation or expiration. Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. - -BCHBTC uses [Binance](https://www.binance.com/en/support/announcement/ade106fd65974a9982fc5a32e063d0b0), [Coinbase Pro](https://help.coinbase.com/en/coinbase/getting-started/general-crypto-education/coinbase-update-on-november-2018-bch-hard-fork), and [Huobi](https://huobiglobal.zendesk.com/hc/en-us/articles/900004372123-Huobi-Global-Will-Support-The-Upcoming-Bitcoin-Cash-BCH-HardFork) for BCH/BTC price information. Most exchanges, namely the three we listed there for constructing the price, only view BCHN as the dominant fork, so their convention of BCH is just referring to BCHN, as is indicated in the hyperlinks. The objective was to construct a portfolio of liquid price feeds that maximized geographical diversity as well as user base with negatively/zero correlated downtimes. Binance and Huobi are widely regarded as the most liquid and highest ADV exchanges in the world, and have been so for quite some time. Further, each of the exchanges has "crypto SOTA" APIs with free REST + WSS functionality with generous rate limits and robust endpoints for prices that any user may hit, both real time and historically speaking. Further, Coinbase Pro has a fairly orthogonal user base to the above exchanges and serves as an additive signal to a notion of "fair value" of BCH/BTC, along with a user friendly API. All three of these exchanges have 24/7 customer support + devops team ensuring highly available programmatic access and have strong redundancy across a variety of geographies. Lastly, because Binance and Huobi also have the most liquid derivatives market for both BCH and BTC pairs, users on their platforms should be able to arbitrage the BCHN uma synths if they so please, thereby increasing popularity of these synthetics. - -The decision to query for BCH/BTC instead of BCH/USD is due to three main reasons. Mostly BTC denominated users want to be able to express short-dated interest in the SHA256d coin space, particularly of BCHN given the recent hard fork. Also, from a capital efficiency standpoint, it is important to notice the magnitude of the correlation between BTC and BCH, which has been strong and positive (1 year perason correlation is approximately 0.75) in all bullish regimes of crypto. Given this, users are able to get by with thinner collateral ratio requirements given that they both tend to trend to together. In other words, more formally, the relative volatility of BCH/USD exceeds that of BCH/BTC by a stat sig amount given the positive correlation between them. Lastly, the use of BCH/USD with BTC as collateral would have resulted in a quanto effect where there would be embedded convexity (correlation conditional gamma) that users would have to either hedge out or be forced to take a view on. Given the only liquid place to hedge that is on Bitmex, and due to their recent legal troubles, we decided it would be inconvenient to impose that on users. Further, while we are no strangers to quanto derivatives, the core thesis here isn't to productize BCH-BTC correlation. - -## Implementation - -The value of BCHBTC for a given timestamp can be determined with the following process. - -1. BCH/BTC should be queried for from Binance, Huobi, and Coinbase Pro for the given timestamp rounded to the nearest second. The results of these queries should be kept at the level of precision they are returned at. -2. The median of the BCH/BTC results should then be taken. -3. This result should be rounded to eight decimal places. - -Additionally, [CryptoWatch API](https://docs.cryptowat.ch/rest-api/) is a useful reference. This feed should be used as a convenient way to query the price in realtime, but should not be used as a canonical source of truth for voters. Users are encouraged to build their own offchain price feeds that depend on other sources. - -Voters are responsible for determining if the result of this process differs from broad market consensus. This is meant to be vague as $UMA tokenholders are responsible for defining broad market consensus. - -This is only a reference implementation, how one queries the exchanges should be varied and determined by the voter to ensure that there is no central point of failure. - -## Security considerations -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users given this is dealing with two of the most liquid cryptocurrencies in the whole cryptoverse.

STABLESPREAD is defined as: `min(max(A - B + 1, 0), 2)`, where `A` refers to an equally weighted basket of {UST, CUSD, BUSD}. B is an equally weighted basket of {USDC, USDT}. UST is TerraUSD, the interchain stablecoin connected by the Cosmos IBC. CUSD is Celo Dollar, the stablecoin on the Celo network. BUSD is Binance USD, a stablecoin issued by Paxos in partnership with Binance. `USDC` is a centralized stablecoin issued by Circle and Coinbase. `USDT` is a non-transparent centralized stablecoin issued by Tether, currently the most used stablecoin on Ethereum. - -## Motivation -The DVM currently does not support the STABLESPREAD price index. - -Supporting the STABLESPREAD price identifier would enable the creation of a linear combination of stablecoin baskets, both existing on Ethereum and other blockchains. Token minters could go short on the STABLESPREAD index, while token holders could go long or use synthetic STABLESPREAD for functional purposes. - -There has been an increasing growth of non-Ethereum based stablecoins over the last few months, and especially over the last week in the case of UST, given the Mirror launch earlier this week. Each of these stablecoins have their own quirks and mechanisms in which they aim to target their peg. There appears to be somewhat of a growing dichotomy in terms of folks who believe that non-Ethereum based stable coins are able to retain their peg better. Currently, there does not exist a mechanism for users to express a view on the relative performance of which basket of stablecoins actually retains it peg better without actually acquiring the underlying constituents of the long basket and picking up a synthetic short position of the other basket. - -Further, we also believe STABLESPREAD can act as a defi credit spread primitive where folks can build other products on top, such as an insurance based product where the premium of the insurance is tied to the divergence between the two baskets of stablecoins. Additionaly, one can view the probability of default of a stablecoin as `1 - min(price, 1)`. Given that each basket of stablecoins is a convex combination, then it is also a convex combination of default probabilities. STABLESPREAD is then a difference of convex combination of default probabilities. We also believe that a CDS (credit default swap) can be built on top of this since they are effectively a function of default probabilities, and once STABLESPREAD gets whitelisted as a price identifier, we will start development on such products. - -Let's walk through some cases to better understand what happens in various cases for STABLESPREAD. If both of these baskets were to trade at their theoretical value, then the resulting value of STABLESPREAD will be 1. If the Ethereum based stablecoin basket loses its peg and appreciates in value relative to the non-Ethereum stablecoin basket, then the value of STABLESPREAD will be less than 1. If the opposite happens, then it will be more than 1. It is important that this only measures "relative ability to maintain peg". That is, if both of them lose their peg in the same form, the resulting value still may be 1. - -There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available. - -## Technical Specification -The definition of this identifier should be: - -- Identifier name: STABLESPREAD -- Base Currency: STABLESPREAD -- Quote Currency: ETH -- Data Sources: {Bittrex: UST/USDT, Uniswap V2: UST/USDT} for UST, {Binance: BUSD/USDT, Uniswap V2: BUSD/USDT} for BUSD, {Bittrex: CUSD/USDT} for CUSD, {Bitfinex: UST/USD, Kraken: USDT/USD} for USDT, {Kraken: USDC/USD, Bitstamp: USDC/USD} for USDC, {Coinbase: ETH/USD, Bitfinex: ETH/USD} for ETH -- Result Processing: For each constituent asset of the basket, the average of both exchanges -- Input Processing: None. Human intervention in extreme circumstances where the result differs from broad market consensus. -- Decimals: 8 -- Rounding: Closest, 0.5 up -- Pricing Interval: 1 second -- Dispute timestamp rounding: down -- Scaling Decimals: 18 (1e18) - -## Rationale -Prices are primarily used by Priceless contracts to calculate a synthetic token’s redemptive value in case of liquidation or expiration. Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. - -For each of the constituents of STABLESPREAD- UST, CUSD, BUSD, USDC, USDT, we picked the two most liquid exchanges, including both CeFi and DeFi sources for diversity. Further, each of the CeFi exchanges has "crypto SOTA" APIs with free REST + WSS functionality with generous rate limits and robust endpoints for prices that any user may hit, both real time and historically speaking. Most of these CeFi exchanges have 24/7 customer support + devops team ensuring highly available programmatic access and have strong redundancy across a variety of geographies. On the DeFi side, Uniswap V2 and Balancer are widely regarded as high quality AMMs. - -The objective for STABLESPREAD was to construct a portfolio of the most liquid and active non-Ethereum based stablecoins, and rather than using some complicated weighting scheme, we are initially imposing uniform weighting. If it turns out there is some user feedback around doing a market-cap weighting, ADV-weighting, etc. that can be future work for us. We also experimented with a variety of functional forms of computing a divergence of these two baskets to represent a credit spread. Computing the ratio of them had some promising properties, namely non-negativity constraints, but the nonlinearity of it had some subpar properties that might cause unfriendly UX as liquidations might cascade if the denominator went down X% as opposed to the numerator. So, we settled on an affine transformation, where if both baskets are indeed the same then the result will be 1. - -## Implementation - -The value of STABLESPREAD for a given timestamp can be determined with the following process. - -1. UST, CUSD, BUSD, USDT, USDC should be queried for from the exchanges listed in the "Technical Specification" section for the given timestamp rounded to the nearest second. The results of these queries should be kept at the level of precision they are returned at. -2. For each one, the average of the prices should be calculated. -3. Then, calculate 1/3 * UST + 1/3 * CUSD + 1/3 * BUSD, denote this as `A` -4. Next, calculate 1/2 * USDC + 1/2 * USDT, denote this as `B` -5. Perform A - B + 1 -6. Perform the maximum of the result of step 4 and 0. This is to ensure non-negativity. -7. Perform the minimum of the result of step 5 and 2. This is to ensure symmetry. -8. Take the result of step 6 and divide by the value of ETH/USD. -9. This result should be rounded to eight decimal places. - -Additionally, [CryptoWatch API](https://docs.cryptowat.ch/rest-api/) is a useful reference. This feed should be used as a convenient way to query the price in realtime, but should not be used as a canonical source of truth for voters. Users are encouraged to build their own offchain price feeds that depend on other sources. - -Voters are responsible for determining if the result of this process differs from broad market consensus. This is meant to be vague as $UMA tokenholders are responsible for defining broad market consensus. - -This is only a reference implementation, how one queries the exchanges should be varied and determined by the voter to ensure that there is no central point of failure. - -As an example of how one may go about constructing such a feed programmatically, here is one that was put together as a standalone script with minimal dependencies: https://gist.github.com/chicfilabae/3dff8aef233e4b9e5315daa7a835867d. As always, double-check the implementation as well as include additional measures for reliability to ensure reasonable assumptions around when the graph or cryptowatch isn't available. - -## Security considerations -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users given this is dealing with some of the most liquid stablecoins in the whole cryptoverse, and the relative price volatility of them has been rather low due to their stablecoin properties. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. diff --git a/research/uma/umips/umip-29.md b/research/uma/umips/umip-29.md deleted file mode 100644 index 42af31a0..00000000 --- a/research/uma/umips/umip-29.md +++ /dev/null @@ -1,128 +0,0 @@ -## Headers -| UMIP-29 | | -|------------|----------------------------------------------------------| -| UMIP Title | Add EURUSD, CHFUSD and GBPUSD as price identifiers | -| Authors | Pascal Tallarida (pascal@jarvis.network) | -| Status | Approved | -| Created | December 22, 2020 | - -## Summary -The DVM should support price requests for the EURUSD, GBPUSD and CHFUSD price index. - -## Motivation -The DVM currently does not support the EURUSD, GBPUSD and CHFUSD index. - -### Cost: -While Forex data are free through open centralized exchange, brokers, and other sources APIs, the most reliable are paid.

TraderMade endpoints are queried based on the OHLC period's close time. - -As an example, a request for a EURUSD price at 2020-11-11-01:52:16 should use query for the period ending at 2020-11-11-01:53:00 and use the open price. - -The TraderMade endpoint used would be: https://marketdata.tradermade.com/api/v1/minute_historical?currency=EURUSD&date_time=2020-11-11-13:01&api_key=apikey - -EURUSD, GPBUSD and CHFUSD should then be rounded to 5 decimals. - -TraderMade’s price feed is an aggregated feed from multiple Tier One and Two Banks, Market-Makers and Data Providers.

Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as a official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation). A reference TraderMade implementation that is used by liquidator and dispute bots can be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/TraderMadePriceFeed.js). - -TraderMade is provided as an accessible source to query for this data, but ultimately how one queries for these rates should be varied and determined by the voter to ensure that there is no central point of failure. - -In the case of a TraderMade outage voters can turn to any other available price feed API or a broker API, as the price feeds for the forementioned financial assets does not differ much between different providers. There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes. For this case, we provide options for additional price feed providers that voters could utilize. - -## Additional price feed providers - -### FXMarketAPI - -Documentation for the API can be found [here](https://fxmarketapi.com/documentation#live_rates). - -- Live price feed data -- Historical prices based on date and time -- Registration is free and provides 500 free requests -- Paid plans available -- OHLC request can be used to grab the last closing price before a weekend or a non-working day - -Example requests: - -- Live Rate for EURUSD: `https://fxmarketapi.com/apiliveapi_key=api_key¤cy=EURUSD` -- OHLC for a certain date on a currency pair: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=EURUSD&date=2020-12-23&format=ohlc` -- Request for EURUSD price at a certain date and time: `https://fxmarketapi.com/apihistorical?api_key=api_key¤cy=EURUSD&date=2020-12-23-15:50` - -### FCS API - -Documentation for the API can be found [here](https://fcsapi.com/document/forex-api). - -- 500 API Calls with Free Plan -- Live price data accessible with Free Plan - Updated every 60 seconds or less -- Historical data accessible with the Basic Paid Plan - 10$ per month - -Example requests: - -- Live Rate for EUR/USD: `https://fcsapi.com/api-v3/forex/latest?symbol=EUR/USD&access_key=api_key` -- Historical price for a certain date for EUR/USD - gives back the OHLC: `https://fcsapi.com/api-v3/forex/history?symbol=EUR/USD&period=1D&from=2020-12-23&to=2020-12-24&access_key=api_key` -- Price of EUR/USD between certain dates and times - gives a breakdown on the price each 1 minute between 12:00 and 12:30: `https://fcsapi.com/api-v3/forex/history?symbol=EUR/USD&period=1M&from=2020-12-23T12:00&to=2020-12-23T12:30&access_key=api_key` - -## Security considerations -Adding this new identifier by itself poses a little security risk to the DVM or priceless financial contract users.

Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of EURUSD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap on EUR/USD, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. - -In the past the CHF was pegged to the EUR, but in 2015 this pegged was removed by the Swiss Central Bank in a surprise move, which caused a huge volatile movement on the CHF price. Such movement could put the CHF below the 100% collateralization ratio, although it is highly unlikely to happen. This risk could appear again one day if the peg is reinstated. In the forementioned situation the CHF lost 20% within one day. However with a higher required collateralization ratio such events can be mitigated. diff --git a/research/uma/umips/umip-3.md b/research/uma/umips/umip-3.md deleted file mode 100644 index d168aaed..00000000 --- a/research/uma/umips/umip-3.md +++ /dev/null @@ -1,242 +0,0 @@ -## Headers -UMIP 3 -

ELASTIC_STABLESPREAD/USDC is defined as: `min(max(A - B + 1, 0), 2)`, where `A` refers to an equally weighted basket of {ESD, FRAX, BAC}. B is an equally weighted basket of {USDC, USDT}. ESD is Empty Set Dollar, an algorithmic stablecoin on Ethereum with a dynamic supply model. FRAX is a fractional-algorithmic stablecoin on Ethereum that operates on a creative approach to maintaining a peg via a partially collateralized approach. BAC is Basis Cash, a dynamic supply stablecoin on Ethereum, essentially a version of what the original Basis project meant to be a few years ago. `USDC` is a centralized stablecoin issued by Circle and Coinbase. `USDT` is a non-transparent centralized stablecoin issued by Tether, currently the most used stablecoin on Ethereum. - -## Motivation -The DVM currently does not support the ELASTIC_STABLESPREAD/USDC price index. - -Supporting the ELASTIC_STABLESPREAD/USDC price identifier would enable the creation of a linear combination of stablecoin baskets, both traditional Ethereum-based stablecoins as well as newer elastic-supply based models on Ethereum. Token minters could go short on the ELASTIC_STABLESPREAD/USDC index, while token holders could go long or use synthetic ELASTIC_STABLESPREAD/USDC for functional purposes. - -There has been an increasing growth of seigniorage + elastic-supply based stablecoins over the last few months, and especially over the last few weeks given the success of ESD's launch. Each of these stablecoins have their own quirks and mechanisms in which they aim to target their peg. Historically, it appears that the elastic-supply based stablecoins are more susceptible to feedback loops where they will stay above their peg for an extended period of time or below their peg for an extended period of time. Currently, most of these are trading at a premium. Users will now be able to speculate on the "premium" of the seigniorage model for elastic supply based stablecoins. Currently, there does not exist a mechanism for users to express a view on the relative performance of which basket of stablecoins actually retains it peg better without actually acquiring the underlying constituents of the long basket and picking up a synthetic short position of the other basket. - -Further, we also believe ELASTIC_STABLESPREAD/USDC can act as a defi credit spread primitive where folks can build other products on top, such as an insurance based product where the premium of the insurance is tied to the divergence between the two baskets of stablecoins. Additionaly, one can view the probability of default of a stablecoin as `1 - min(price, 1)`. Given that each basket of stablecoins is a convex combination, then it is also a convex combination of default probabilities. ELASTIC_STABLESPREAD/USDC is then a difference of convex combination of default probabilities. We also believe that a CDS (credit default swap) can be built on top of this since they are effectively a function of default probabilities, and once ELASTIC_STABLESPREAD/USDC gets whitelisted as a price identifier, we will start development on such products. - -Let's walk through some cases to better understand what happens in various cases for ELASTIC_STABLESPREAD/USDC. If both of these baskets were to trade at their theoretical value, then the resulting value of ELASTIC_STABLESPREAD/USDC will be 1. If the Ethereum based stablecoin basket loses its peg and appreciates in value relative to the non-Ethereum stablecoin basket, then the value of ELASTIC_STABLESPREAD/USDC will be less than 1. If the opposite happens, then it will be more than 1. It is important that this only measures "relative ability to maintain peg". That is, if both of them lose their peg in the same form, the resulting value still may be 1. - -There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available. - -## Technical Specification -The definition of this identifier should be: - -- Identifier name: ELASTIC_STABLESPREAD/USDC -- Base Currency: ELASTIC_STABLESPREAD -- Quote Currency: USDC -- Data Sources: {Uniswap V2: FRAX/USDC} for FRAX, {Uniswap V2: ESD/USDC} for ESD, {Uniswap v2: BAC/DAI} for BAC, {Bitfinex: UST/USD, Kraken: USDT/USD} for USDT, {Coinbase-Pro: DAI/USD, Kraken: DAI/USD} for (Multi Collateral) DAI, {Kraken: USDC/USD, Bitstamp: USDC/USD} for USDC -- Result Processing: For each constituent asset of the basket, the average of exchanges.

Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. diff --git a/research/uma/umips/umip-33.md b/research/uma/umips/umip-33.md deleted file mode 100644 index ee18793c..00000000 --- a/research/uma/umips/umip-33.md +++ /dev/null @@ -1,183 +0,0 @@ -# Disclaimer - -The AMPLUSD price identifier has been deprecated.

Price requests from contracts created before this time will not be impacted. - -Reasoning: The new EMP template proposed in [UMIP-54](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-54.md) requires that all price identifiers be scaled to 18 decimals. There are live contracts using the old EMP template which require this price identifier to be scaled equal the number of decimals in USDC (6). Because of this, the DVM could return prices incorrectly for new contracts that use this identifier. - -## Headers - -- UMIP-33 -- UMIP title: Add AMPLUSD, USDAMPL as price identifiers -- Author (alex, abgtrading30@gmail.com) -- Status: Approved -- Created: December 20, 2020 - -## Summary (2-5 sentences) - -The DVM should support price requests for the AMPL/USD and USD/AMPL price index. - -## Motivation - -The DVM currently does not support the AMPL/USD or USD/AMPL price index. - -Supporting the AMPLUSD and USDAMPL price identifiers would enable the creation of a synthetic AMPLUSD and USDAMPL token, backed by USD. Token minters could obtain short exposure on the AMPL/USD index, while token holders could go long or use synthetic AMPL for functional purposes. - -There are multiple practical uses and trading strategies for synthetic AMPL which include avoiding rebases, minting tokens for short exposure, and hedging underlying AMPL exposure. Background on Ampleforth and its rebase mechanism can be found in the project whitepaper: https://www.ampleforth.org/papers/ - -There is little cost associated with adding this price identifier, as there are multiple free and easily accessible data sources available. - -## Technical Specification - -The definition of this identifier should be: - -- Identifier name: AMPLUSD -- Base Currency: AMPL -- Quote Currency: USD -- Data Sources: FTX, Bitfinex, Gate.io -- Result Processing: Median -- Input Processing: None.

Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. - -There is a lot to consider when deciding Ampleforth’s data sources. Part of Ampleforth’s rebase mechanism uses a market oracle, Chainlink, for price feeds. Chainlink sources prices using aggregators (BraveNewCoin, Kaiko, and CryptoCompare) for its volume weighted price. This is problematic as Kaiko is not a free resource and CryptoCompare is only free for personal projects and capped at 250,000 lifetime calls. - -Other factors that are relevant to the volume and price for AMPL: - -- Compared to other ERC-20 tokens, there is a high level of complexity for centralized exchanges to integrate AMPL due to its daily changes in supply potentially limiting adoption. -- The project has set up liquidity mining (Geyser programs) to incentivize liquidity on decentralized exchanges (Uniswap, Sushiswap, Balancer). -- One of its centralized exchanges, Kucoin, suffered a hack in September. Since the hack, there have been moments where the Kucoin pairs have reflected a lower market price compared to other exchanges. This creates hesitation in using it as one of the main data sources even though it has a high percentage of reported centralized exchange volume. - -The option being proposed is to use the spot market prices from FTX, Bitfinex, and Gate.io. As AMPL is added to more exchanges, the technical specification of this identifier could be modified to reflect more reliable exchanges based on volume. - -Users should use these aggregators as a convenient way to query the price in real-time, but should not be used as a canonical source of truth for voters. Users are encouraged to build their own offchain price feeds that depend on other sources. - -## Implementation - -The value of AMPLUSD and USDAMPL for a given timestamp can be determined with the following process: - -1. AMPL/USD should be queried from Gate.io, Bitfinex, and FTX for that timestamp rounded to the nearest second. The results of these queries should be kept at the level of precision they are returned at. -2. The median of the AMPL/USD results should then be taken and determined whether that median differs from broad market consensus. -3. This result should be rounded to six decimal places. -4. The inverse of the AMPL/USD median from step 2 is then taken (1/AMPLUSD) to determine the USD/AMPL price. -5. The USD/AMPL result should be rounded to six decimal places. -6. The value for the USD/AMPL results should then be compared to determine whether the median differs from broad market consensus. - -This is meant to be vague as the tokenholders are responsible for defining broad market consensus. Ultimately, how one queries the exchanges should be varied and determined by the voter to ensure that there is no central point of failure. - -While it's important for tokenholders to have redundancy in their sources, bots and users that interact with the system in real time need fast sources of price information. In these cases, it can be assumed that the exchange median is accurate enough. - -The chosen AMPL/USD and USD/AMPL endpoints are: - -1.

The contracts that were modified: - -- `PerpetualCreator.sol` was modified to create`SynthereumPerpetualPoolPartyCreator.sol` -- `Perpetual.sol` was modified to create `SynthereumPerpetualPoolParty.sol` -- `SynthereumDerivativeFactory.sol` is a new contract that is derived from `SynthereumPerpetualPoolPartyCreator.sol` to restrict deployment access. - -Below is an overview of the modifications: - -The deposit/withdraw and create/redeem functions in `SynthereumPerpetualPoolParty.sol` can only be called by the Synthereum protocol. - -All funding rate logic was removed from `SynthereumPerpetualPoolParty.sol`. In Synthereum, the token sponsor is a contract and any synthetic asset bought/sold on the open market can be created/burned in exchange for its exact value in collateral based on a price feed, which guarantees a perfect arbitrage between Synthereum and DEXs, thus maintaining the peg. - -Since our assets are perpetual, if we wanted to upgrade or change something in the derivative contract (change of collateral, for instance) it would require a new perpetual token to be deployed, which will create friction for end-users, liquidity providers, and protocols where our synthetic tokens are integrated. Thus, we wanted to be able to deploy a new derivative contract, but link it to the preexisting perpetual token. This upgradability was added in `SynthereumPerpetualPoolPartyCreator.sol`. - -`SynthereumPerpetualPoolParty.sol` was split into separate libraries in order to optimize the gas consumption. Note: this is detailed below in the Technical Specification section. - -The `emergencyShutdown` functionality in `SynthereumPerpetualPoolParty.sol` has been modified to not only be callable by the UMA DVM, but also by the Jarvis DAO. - -Once `SynthereumDerivativeFactory.sol` receives the `Creator` role it will register every `SynthereumPerpetualPoolParty.sol` that is deployed through it with `Registry.sol` so they can request prices from the DVM. - -# Motivation - -The forking of the UMA contracts was a necessary step in order to align the `DerivativeFactory.sol` with the needs of our project. It also allowed us to go faster with the development as otherwise we would have had to add tons of code and complexity to our code base. -Making some modifications to the contract allowed us to achieve lower gas consumption for deployment, add the functionality to link newly deployed derivatives to an already existing synthetic tokens and to also deploy new derivatives thus creating new synthetic tokens. Adding this functionality provides our users with a better UX, due to the fact that there won't be multiple versions of the same synthetic asset even if a new derivative contract is deployed for that synthetic asset, thus there won't be the need for users or liquidity providers to transfer their funds in order to back another synthetic asset. -Giving `Creator` role to `DerivativeFactory.sol` would allow our synthetic assets to be backed by the UMA liquidation/dispute system, since every newly deployed derivative (`PerpetualPoolParty.sol`) is registered with the DVM. - -# Technical Specification - -### Here is a breakdown on the whole deployment process of a new derivative: - -1. Our DAO address (which is currently a team address until the DAO is set up) calls `deployPoolAndDerivative` of `SynthereumDeployer.sol`. -2. `SynthereumDeployer.sol` calls `createPerpetual` function of `SynthereumDerivativeFactory.sol` and this function will call `createPerpetual` function of the base contract `SynthereumPerpetualPoolPartyCreator.sol` that will deploy the new `SynthereumPerpetualPoolParty.sol`. -3. `SynthereumDeployer.sol` calls `createPool` function of `SynthereumPoolFactory.sol` and this function will call `createPool` function of the base contract `SynthereumPoolCreator.sol` that will deploy the new `SynthereumPool.sol`. -4. `SynthereumDeployer.sol` links the newly deployed `SynthereumPool.sol` to the newly deployed `SynthereumPerpetualPoolParty.sol` and assignes the roles in `SynthereumPerpetualPoolParty.sol` to `SynthereumPool.sol`, which are `Admin` and `Pool`. - -### Modifications done: - -- The derivative contract (`SynthereumPerpetualPoolParty.sol`) has a restricted access for deposit/withdraw and create/redeem, which prevents anyone but Synthereums pool (`SynthereumPool.sol`) to mint or redeem synthetic assets; this prevent an attacker to "spam" our protocol by increasing the Global Collateralization Ratio (GCR). -- `SynthereumDerivativeFactory.sol` contract allow to deploy derivatives (create new synthetic tokens) or deploy a derivative and link it to an already existing synthetic token. -- `SynthereumDerivativeFactory.sol` is the derived contract of `SynthereumPerpetualPoolPartyCreator.sol`(that uses `SynthereumPerpetualPoolPartyLib.sol` for gas optimization). Adding this contract as Creator role in UMA registry, allow the derivatives deployed to integrate the DVM -- When deploying a new derivative contract (`SynthereumPerpetualPoolParty.sol`) the `SynthereumDerivativeFactory.sol` can set any ERC-20 token as collateral, meaning that it allows the support of multiple collateral tokens including those that accrue interest (inflationary). This adds additional flexibility to the contract in maintaining a collateral currency which is preferred by the community and also most stable in terms of technical risks. -- The forked and updated version of `SynthereumPerpetual.sol`, now called `SynthereumPerpetualPoolParty.sol`, deployed by `SynthereumDerivativeFactory.sol` is set with gas optimization in mind. Due to adding more functionalities to it the gas limit for deployment was overpassed, so the overall architecture was changed by using library contracts which hold some of the functionalities, thus significantly lowering the gas costs of deployment. -- Removing of `fundingRate` as a functionality from the `Perpetual.sol`(`SynthereumPerpetualPoolParty.sol`), since we do not need such feature in order to maintain the peg; Synthereum's synthetic assets are always redeemable for their exact value in collateral tokens against a price feed, insuring constant arbitrage, and therefore a strong peg. -- Two types of roles were set-up in the `SynthereumPerpetualPoolParty.sol` which is deployed by the `SynthereumDerivativeFactory.sol` - Admin and Pool. The pools act as a token sponsors and they are attached to the corresponding derivative, thus allowing the calling of Mint,Exchange and Redeem functions. Admin role has the ability to add new pools to a derivative or remove it. -- `EmergencyShutdown` functionality was updated in order to allow both UMA DAO and Jarvis DAO to have access to it in the case of an issue that puts in danger the funds of users. - -### Nesting of the contracts: - -1. `Perpetual.sol`, now called `SynthereumPerpetualPoolParty.sol` is a derived contract that inherit from `PerpetualLiquidatable.sol`, now called `SynthereumPerpetualLiquidatablePoolParty.sol`. -2. `PerpetualLiquidatable.sol`, now called `SynthereumPerpetualLiquidatablePoolParty.sol` is derived contract that inherit from `PerpetualPositionManager.sol`, now called `SynthereumPerpetualPositionManagerPoolParty.sol`. -3. `PerpetualPositionManager.sol`, now called `SynthereumPerpetualPositionManagerPoolParty.sol` is derived contract that inherit from `FeePayer.sol`, now called `SynthereumFeePayerPoolParty.sol`. - -Each one of These has its own library for gas optimization: -1. `SynthereumPerpetualPoolPartyCreator.sol` uses `SynthereumPerpetualPoolPartyLib.sol` for gas optimization. -2. `SynthereumPerpetualLiquidatablePoolParty.sol` uses `SynthereumPerpetualLiquidatablePoolPartyLib.sol` for gas optimization. -3. `SynthereumPerpetualPositionManagerPoolParty.sol` uses `SynthereumPerpetualPositionManagerPoolPartyLib.sol` for gas optimization. -4. `SynthereumFeePayerPoolParty.sol` uses `SynthereumFeePayerPoolPartyLib.sol` for gas optimization. - -# List of deployed contracts: - -- [SynthereumFinder](https://etherscan.io/address/0xD451dE78E297b496ee8a4f06dCF991C17580B452) -- [SynthereumDeployer](https://etherscan.io/address/0x592108F92F6e570f1A47f32c459a03c90aCe05a7) -- [SynthereumPoolRegistry](https://etherscan.io/address/0xefb040204CC94e49433FDD472e49D4f3538D5346) -- [SynthereumFactoryVersioning](https://etherscan.io/address/0x1fBb59a3Fff02989342FD0761AE62f01334b5244) -- [SynthereumSyntheticTokenFactory](https://etherscan.io/address/0xAb6EEDb096376a493E0e888D2738a6a0A493cC3e) -- [FeePayerPoolPartyLib](https://etherscan.io/address/0xB0d0A057060c266b76B110C762471C91a80eD292) -- [PerpetualPositionManagerPoolPartyLib](https://etherscan.io/address/0xf953f99F6E3907D14658f906988EacDc08387AAd) -- [PerpetualLiquidatablePoolPartyLib](https://etherscan.io/address/0xA758F41c32dB16BF9354ca230a9eC73edd0AD4c0) -- [PerpetualPoolPartyLib](https://etherscan.io/address/0xd8C00bD1BD98D0880e0eA70af81a65348aE73Ef2) -- [SynthereumDerivativeFactory](https://etherscan.io/address/0x98c1f29A478fb4e5da14c2BcA0380e67ac2A964a#code) -- [SynthereumPoolLib](https://etherscan.io/address/0xDB026D6c3450F5F28f3a035E158E1B68AfCE8f9F) -- [SynthereumPoolFactory](https://etherscan.io/address/0x2097E7f338eB44C69a48c3f9eBea7dEeeb88f63F) - -# Implementation and code base - -The `SynthereumDerivativeFactory` contracts can be found here are available for a review by anyone [here](https://gitlab.com/jarvis-network/apps/exchange/mono-repo/-/tree/feature/uma-integration-part-2/libs/contracts/contracts). - -The `SynthereumPerpetualPoolParty` contracts can be found and are available for a review by anyone [here](https://gitlab.com/jarvis-network/apps/exchange/UMAprotocol/-/tree/jarvis-dev/for-publish/0.3.x/packages/core/contracts). - -# Security considerations - -The forked code has been officially audited by a third party company (Halborn), with whom we are working on security across our whole project.

As example a possibility for an attacker to exploit our protocol, which could potentially drain capital from PerpetualPoolParty contract, thus rendering synthetic assets linked to those pools become undercapitalized (collateralization ratio to drop below 100%) and therefore becoming worthless. In order to mitigate this as we mentioned we'll cap the system until we are fully audited and have ran several whitehack test and also we'll be adding a daily withdraw limitation, so even in the worse case scenario we as a foundation can cover the losses of users. We'll also purchase cover on that limit using various protocols (Nexus, Unslashed) as well as setting up our own insurance fund. - -Currently there is no economical incentive for liquidating undercapitalized positions (positions where the CR drops below 100%). Although, Forex pairs are not very volatile and rarely move by more than 10% a year, and we have set liquidation at 120% so it is quite unlikely to experience this situation. diff --git a/research/uma/umips/umip-35.md b/research/uma/umips/umip-35.md deleted file mode 100644 index 8dfdf847..00000000 --- a/research/uma/umips/umip-35.md +++ /dev/null @@ -1,65 +0,0 @@ -# Headers - -| UMIP - 35 | | -| ---------- | ----------------------------------- | -| UMIP Title | Add bwBTC/ETH SLP and bBadger as collateral currencies | -| Authors | BitcoinPalmer, mitche50, J au Defi, Defi Frog | -| Status | Approved | -| Created | January 7, 2021 | - -## Summary - - -This UMIP will add bwBTC/ETH Sushiswap liquidity provider (SLP) and bBadger, two BadgerDAO vault LP tokens, as approved collateral currencies. - -This will involve adding it to the whitelist and adding a flat final fee to charge per-request.

Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. More complex computations (like incorporating additional exchanges, calculating a TWAP or VWAP, or imposing price bands, etc.) have the potential to add a greater level of precision and robustness to the definition of this identifier, particularly at settlement of each expiring synthetic token. - -The addition of DSDUSD and USDDSD fits into a larger goal of advancing the adoption of the UMA protocol by allowing DSD to be used as collateral for minting a stable coin among a suite of [OpenDAO](https://opendao.io) stable coins. This furthers adoption of the protocol by encouraging a convergence of capital from different projects and increasing TVL. - -Currently the largest exchange with USD or stablecoin markets for DSD is [Uniswap](https://info.uniswap.org/pair/0x66e33d2605c5fb25ebb7cd7528e7997b0afa55e8) (~90% volume). If liquidity is withdrawn too fast there may be a risk in the price peg, and therefore the integrity of the system. - -In the current setting, there will need to be a significant event that erodes confidence in DSD and the token, at the same time where Uniswap liquidity is withdrawn too quickly en masse. However this may pose a security issue depending on the depth of DSDUSD liquidity on Uniswap. This may be improved by listing on additional exchanges with genuine volume. -Over time, as liquidity in the DSD token migrates across platforms, this identifier can be re-defined to add exchanges, remove exchanges, or change the way that the price is calculated. Any re-definition would be done via off-chain social consensus by $UMA-holders, and ultimately reflected in the way that $UMA-holders vote upon the price of DSDUSD and USDDSD when called to do so by disputers, or at settlement. - - - -## Implementation - -The value of this identifier for a given timestamp should be determined by querying the price from DSDUSDC pair https://info.uniswap.org/pair/0x66e33d2605c5fb25ebb7cd7528e7997b0afa55e8 on Uniswap for that timestamp. Most of the DSD trading volume happens on Uniswap, which forms the broad market consensus. -While it's important for tokenholders to have redundancy in their sources, bots and users that interact with the system in realtime need fast sources of price information. In these cases, it can be assumed that the price on Uniswap is accurate enough. - -Dynamic Set Dollar will provide the live price feed on the website publicly, and may offer API access in the future. - -## Security considerations -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. \ No newline at end of file diff --git a/research/uma/umips/umip-38.md b/research/uma/umips/umip-38.md deleted file mode 100644 index cacf723d..00000000 --- a/research/uma/umips/umip-38.md +++ /dev/null @@ -1,245 +0,0 @@ -# Disclaimer - -These price identifiers have been deprecated.

The reference UMA liquidator bot implementation already has a two-hour TWAP Uniswap implementation. - -Post Cutoff Cost: Calculating an aggregated statistic of compound USDC borrow rates on a confirmed range of blocks on the Ethereum blockchain is easy. All of the needed data can be computed from event logs on any Ethereum full node. An archive node allows direct querying of this data via contract methods. Additionally, this data can be accessed through querying the Compound Subgraph on the Graph Protocol, then running a simple aggregation function. - -Opportunity: The usage of a two-hour TWAP for liquidations, then an aggregated price at expiration is similar to UMIP-22. This setup allows us to create futures. Compound USDC Borrow APR futures can help borrowers and traders hedge against interest rate volatility allowing them to "lock-in" future costs from Compound loans. This will enable taking multi-collateral backed loans out on Compound for new use cases. Other users may wish to speculate on the demand for borrowing USDC on Compound for a specific month in the future. Others may simply wish to hedge their deposit interest rate volatility. Providing a price feed for the settlement of a financial contract is a prerequisite. - -Example Synthetic: `CAR-USDC-FEB28` will be a token that settles to the total annualized interest rate of borrowing USDC on Compound for (roughly) the month of February. - -Example user: A trader takes out a large loan from Compound and the current APR is 10%. Compound APRs are volatile, however, the trader wishes to lock-in this APR for the next month. The trader can buy synthetic tokens tracking this price index. If APRs increase, the trader owes more interest on their loan, but their synthetic increases in value enough to cover the cost of the increased interest. - -## Markets & Data sources - -### Pre Cutoff -This price should be queried from the highest volume Uniswap pool (Whichever one is deemed more legitimate by the UMA token holders) on Ethereum where at least one asset in the pair is CAR. It's expected that a single Uniswap pool will have 99% of the liquidity and volume so confusion will not arise. - -### Post Cutoff - -The source of truth for this data is the Compound USDC cToken's (cUSDC) `borrowRatePerBlock()` method. As of the writing of this UMIP, the agreed-upon cUSDC smart contract address is `0x39aa39c021dfbae8fac545936693ac917d5e7563`. This price identifier aggregates the value returned by `borrowRatePerBlock()` over every block from the 30 days ending at the cutoff/expiration timestamp (`1614470400` for `COMPUSDC-APR-FEB28/USDC` and `1616889600` for `COMPUSDC-APR-MAR28/USDC`). - -It is recommended to gather the raw data from an Ethereum archive node. Alternatively, this data is indexed in the [Graph Protocol](https://thegraph.com/explorer/subgraph/graphprotocol/compound-v2). As of writing this UMIP, Graph Protocol is free. However, they have plans to start charging for access in the future. In the future, querying 30 days worth of blocks may cost up to $20 USD. This UMIP's price identifier will only be used for the DVM to return the synthetic token's expiration price. Therefore, this high price won't be incurred by liquidator bots. - -Raw data is also available for download at the [Tendies Exchange public endpoint](https://cache.tendies.exchange/borrow_rate_per_block.json). This endpoint is updated with every new block but delayed by 20 block confirmations. This endpoint is free to use. To generate a similar file, governors can use and/or modify this [open source indexer script](https://github.com/evanmays/tendies-exchange/tree/master/indexer). - -All of these endpoints give the borrow rate per block for historical blocks, however converting this data to APR (and aggregation) is still required. (Read the implementation section) - -## Price Feed Implementation -### Pre Cutoff -This price should be updated every second by using the time-weighted average price from the past 2 hours. Data can be queried from Uniswap event logs on any Ethereum full node. - -Liquidator bots with access to an Ethereum full node can use this [Uniswap implementation](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) for free to query current and historical data. - -### Post Cutoff - -The intention is that the aggregated APR won't be used for liquidations. This is because the DVM only switches to this price at the CAR token expiration. By the time this aggregated statistic will be used (at expiration), liquidations won't be possible anymore. Therefore, a price feed isn't required for liquidator bots to track this rolling APR. All liquidations will use a two-hour TWAP price feed.

This is only required for the post-cutoff price. - -**8. Pricing Interval** - Per block - -**9. Dispute timestamp rounding** Round down (previous timestamp) - -## Rationale - -### Pre-cutoff - -Due to the lack of ambiguity on calculating the TWAP, UMA token holders should all converge on the same price. However, to be consistent with post-cutoff rounding, we will round pre-cutoff to 2 decimal places. - -We use the time-weighted average price (TWAP) as opposed to the average price at the end of each block. This causes collateralization requirements to be more accurate as block times are highly variable. - -Most volume is expected to be on the Uniswap USDC/CAR pools. - -Further rationale for using a two-hour TWAP is in the UMIP-22 Rationale section. - -### Post-cutoff - -We're using a rolling 30 day period to increase the cost of manipulating the APR price. - -We use geometric mean, as opposed to arithmetic mean, to include the effect of interest compounding. - -We use an annual percentage rate, as opposed to a monthly percentage rate, to increase usability. 1) Annual rates are large enough numbers that, combined with an easy to understand 1-to-1 APR to USDC ratio, result in prices (most of the time) in the range of $1 to $30. 2) Annual rates are more commonly used when discussing loan borrowing rates. - -For clarification, here's an example of the 1-to-1 conversion. 7% APR is $7USDC and 3% APR is $3USDC. - -There is a ground-truth for this price identifier. The ground truth data is in the Compound smart contract on the Ethereum blockchain. Any differences in UMA governor results for this price identifier should be due to rounding errors that propagate through the calculation (numerical instability) as opposed to multiple data sources being the truth (as is the case with looking at the price of bitcoin on different exchanges). - -We mitigate the effects of numerical instability by rounding to the nearest two decimal places. Different algorithms for calculating the geometric mean result in tiny differences in the result. Rounding to 2 decimal places hides small differences in geometric mean calculations. For example, if person A calculates the price request result as $7.53453USDC and person B calculates the price request result as $7.53489USDC, both will agree on $7.53USDC. - -## Implementation - -### Pre-cutoff - -For price requests made before the cutoff, (`1614470400` for `COMPUSDC-APR-FEB28/USDC` and `1616889600` for `COMPUSDC-APR-MAR28/USDC`), use the same two-hour TWAP calculation implementation from UMIP-22. - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the USDC/CAR pool returns at the end of the latest block whose timestamp is <= the timestamp that is queried for. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. As the token price will already implicitly be tracking the COMPUSDC-APR-TWAP-OR-30DAY-FEB28/USDC or COMPUSDC-APR-TWAP-OR-30DAY-MAR28/USDC price, it should be left as returned without any scaling transformation. -6. The final price should be returned with the synthetic token as the denominator of the price pair and should be submitted with 6 decimals. But rounded to 2 decimal places. For example, if the APR is 7.38482747%, then we round to 2 decimal places and convert 1-to-1 to USDC for $7.38USDC. However, USDC on Ethereum uses 6 decimal places so voters must submit $7.380000USDC. - -### Post-cutoff - -For price requests made after or on the cutoff, (`1614470400` for `COMPUSDC-APR-FEB28/USDC` and `1616889600` for `COMPUSDC-APR-MAR28/USDC`), use the below geometric mean calculation. - -This implementation works with the dataset from [Tendies Exchange public endpoint](https://cache.tendies.exchange/borrow_rate_per_block.json). To use it with other datasets, modify the `getBorrowRatePerBlock()` function. This implementation is updated as an [open source price feed script](https://github.com/evanmays/tendies-exchange/tree/master/indexer). - -The script below expects a `start_block` and `end_block` for the 30 day period. UMA token holders should define these as follows. -``` -start_block = The block the DVM Timestamp was mined in -start_timestamp = DVM Timestamp - 30 days -end_block = The block mined most recently after start_timestamp -``` - -These values can be put into this script. The script also expects `expected_blocks_per_year`.

The trading price of CAR is the expected aggregate compound interest rate at the end of February and March. This is slow moving by default, so price manipulation if the two-hour TWAP should be challenging. However, the price may be volatile during earlier periods of the month. This is due to the lack of information about the future. It is expected these prices become less volatile as the cutoff/expiration date nears. - -Anyone relying on this data point should also note that manipulating the APR for a specific block is possible for users with large amounts of capital. These users can deposit this capital into the pool, remove this capital from the pool, or take large loans against the pool to significantly change the interest rate for a block. Aggregated APRs should mitigate this type of manipulation. diff --git a/research/uma/umips/umip-39.md b/research/uma/umips/umip-39.md deleted file mode 100644 index 1a7c2445..00000000 --- a/research/uma/umips/umip-39.md +++ /dev/null @@ -1,308 +0,0 @@ -## HEADERS -| UMIP-39 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add USD/bBadger and USD-[bwBTC/ETH SLP] as supported price identifiers | -| Authors | mitche50, J au Defi, bitcoinpalmer, Defi Frog, Sean Brown (smb2796) -| Status | Approved | -| Created | 1/15/2021 - - -# SUMMARY - -The DVM should support price requests for the below price indexes: -- USD/bBadger -- USD-[bwBTC/ETH SLP] - -# MOTIVATION - -The DVM currently does not support the USD-[bwBTC/ETH SLP], USD/bBadger price identifiers. - -BadgerDAO’s first product is Sett vault, an automated DeFi aggregator focused on tokenized BTC assets.

Rounding** - Round to 18 decimal places - - -# RATIONALE - -**Why this implementation of the identifier as opposed to other implementation designs?** - -This implementation is due to Badger’s main sources of liquidity being on Sushiswap and Uniswap. Currently, only low volume and low depth centralized exchanges have Badger listed, and most liquidity will remain on DEXs as it is incentivized. - -**What analysis can you provide on where to get the most robust prices? (Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges)** - -Sushiswap and Uniswap have the vast majority of Badger volume and depth. These should be used over all other sources. - -**What is the potential for the price to be manipulated on the chosen exchanges?** - -Badger is not a collateral on any loan services and the majority of the liquidity is locked into farming vaults / geysers. The potential risk for this is low. - -**Should the prices have any processing (e.g., TWAP)?** - -Processing is defined in the implementation section. - -# IMPLEMENTATION - -B wrapped tokens have 2 components to finding the underlying value of the tokens associated with them. Each wrapped token has a pricePerFullShare, which is the amount of underlying tokens that 1 b token could be redeemed for through the withdraw function. This underlying token can have different ways to determine its value depending on what type of token it is. - -The price per full share can be found by querying the contract of the token with `getPricePerFullShare` as seen in method 9 on this [contract](https://etherscan.io/address/0x19D97D8fA813EE2f51aD4B4e04EA08bAf4DFfC28#readProxyContract). - -getPricePerFullShare is a pure view logic function in which no one has any authority to manipulate: - -``` -if (totalSupply() == 0) -{ - return 1e18; -} -return balance().mul(1e18).div(totalSupply()); -``` - -This returns the value of the balance of the vault divided by the number of shares to give the user the value of 1 share of the vault token. balance() represents the total balance of the underlying token in the vault. For example, if a user has 1 bBadger, this could be worth 1.2 Badger (which would be the ratio of balance / totalSupply). - -For bBadger you could use the same getPricePerFullShare method (described above) from the contract to get the underlying amount, and then the underlying values can be queried to give the price of one bBadger token in USD. - -For both implemenations, a block number will need to be used. The block number should be the block that is closest to and before the timestamp that the price request timestamp. - -## Determining the WBTC/USD price - -For both of these price identifiers, the WBTC/USD price will need to be used in the pricing calculation. - -To obtain the WBTC/USD price, follow this process. The price request timestamp should be passed as the `timestamp` parameter. - -1. Query for WBTC/ETH prices on Sushiswap and Uniswap -- Voters can obtain this information in any way that they wish.

However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. - -Although these are "wrapped" tokens, an objective value of the underlying collateral can be accurately determined to adequately inform both participating liquidators and disputers. - -The value of collateral can be objective in terms of price per full share * underlying asset value. - -If the vault was hacked in a way that drained funds, the price per full share would decrease in a way that makes the collateral "proportionally recoverable" for all users. There is also insurance from Nexus mutual to consider in terms of valuing the asset in the event of a covered vulnerability - -For context, the wrapping mechanism mints a token that represents a % share of a liquidity pool or vault. This is common practice when providing liquidity to an AMM or depositing into a yield optimizer. Using identifiers like price per full share, an oracle can deterministically calculate the value of what the unwrapped ERC20 tokens would be worth at any given time. - -Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. $UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. diff --git a/research/uma/umips/umip-4.md b/research/uma/umips/umip-4.md deleted file mode 100644 index 7bc4c598..00000000 --- a/research/uma/umips/umip-4.md +++ /dev/null @@ -1,186 +0,0 @@ -# Headers -| UMIP-4 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Register new financial contract with DVM | -| Authors | Matt Rice (matt@umaproject.org), Prasad Tare (prasad@umaproject.org), Chris Maree (chris@umaproject.org), Nick Pai (nick@umaproject.org) | -| Status | Approved 19 May 2020 | -| Created | April 30, 2020 | - - -# Summary - -This UMIP provisionally registers the `ExpiringMultiParty` template with the DVM. -This financial contract template enables the creation of priceless synthetic tokens, as described [here](https://docs.umaproject.org/uma/synthetic_tokens/explainer.html). - -Synthetic tokens are collateral-backed tokens whose value fluctuates depending on the tokens’ reference index. -The proposed contract design has the following features: -- Contract parameters can be customized by the initial deployer -- Anyone can mint synthetic tokens by depositing Dai as collateral -- Anyone can liquidate undercollateralized positions -- Anyone can dispute invalid liquidations within a 2-hour liveness period -- Disputes will be resolved by the DVM, and the contract otherwise does not require an on-chain price feed - -# Motivation - -Up until now, other synthetic token designs have required the smart contract to know the value of the collateral at -all times, as reported by an on-chain price feed. This is a problem because on-chain oracles are costly to maintain -from a gas and DevOps perspective and leaves contracts open to price-feed manipulation attacks. “Priceless” synthetic -tokens differ because they do not require an on-chain price feed to indicate whether the contract is properly collateralized. -Instead, they have a liquidation mechanism that allows anyone to liquidate an undercollateralized position. They can -do so by providing rewards to counterparties or third parties for identifying improperly collateralized positions. -To confirm that these positions are improperly collateralized, these contracts may rely on a “Data Verification -Mechanism” (DVM). This makes the proposed design more decentralized and resilient against manipulation. - -This is the first “priceless” financial contract template to be registered with the DVM. - -# Technical Specification - -“Priceless” synthetic tokens are synthetic tokens that are securely collateralized without an on-chain price feed. -These tokens are designed with mechanisms to incentivize token sponsors (those who create synthetic tokens) to properly -collateralize their positions. These mechanisms include a liquidation and dispute process that allows token holders to be -rewarded for identifying improperly collateralized token sponsor positions. The dispute process relies on an oracle, -the UMA DVM, to settle disputes regarding liquidations. - -A deployment of a priceless synthetic token is defined by the following parameters. The contract template that is -registered with the UMA DVM will hardcode or restrict some of these parameters, as indicated below. All other -parameters can be customized in individual deployments of the contract. - -- expirationTimestamp: These are discretized to monthly expires on the 1st day of each month at 12:00:00 UTC. The max timestamp is June 30, 2021. -- collateralAddress: DAI (0x6b175474e89094c44da98b954eedeac495271d0f). To register additional collateral currencies (e.g. USDC), a new factory contract that has the USDC address in the collateralAddress line would need to be registered and approved by $UMA-holders. To stop supporting DAI, this factory and any other factory with DAI as the collateralAddress would have to be de-registered by $UMA-holder vote. -- priceFeedIdentifier -- syntheticName -- syntheticSymbol -- collateralRequirement -- disputeBondPct -- sponsorDisputeRewardPct -- disputerDisputeRewardPct -- minSponsorTokens -- timerAddress: Hardcoded to 0x0000000000000000000000000000000000000000 -- withdrawalLiveness: Hardcoded to 120 min. -- liquidationLiveness: Hardcoded to 120 min. - -Since this is the first token factory that proposes using Dai as the collateralAddress, this proposal also includes -initializing the finalFees for Dai to 10 Dai for all contracts that use Dai as the collateral currency. The finalFee -parameter is an adjustable DVM parameter controlled by $UMA holders to establish a minimum fee for each price request -that a contract makes. It is intended to introduce a cost to prevent malicious users from spamming the DVM and overloading -it with price requests, but not be so high as to deter disputers from performing their work. - -In proposing that Dai is used as the collateral currency for the synthetic token factory, factors were considered -including: smart contract security, broad usability and acceptability, and on-chain liquidity. These factors are -important because the value of Dai will be used by $UMA-holders to determine the amount of PfC, or profit-from-corruption, -that exists in the UMA ecosystem; therefore $UMA-holders must be able to objectively determine the valuation of Dai. -Additionally, token contracts deployed from this factory will pay fees in Dai to the DVM Store, which will be used to -buy-and-burn $UMA tokens; therefore, Dai liquidity is an important consideration in the approval process. - -## Launching a New Synthetic Token - -To launch a new type of synthetic token for which an existing market does not yet exist, that synthetic token’s smart -contract must first be parameterized and deployed. Anyone (a “Contract Deployer”) can parameterize and deploy this contract. -After the contract is deployed, anyone (“Token Sponsors”) can interact with the contract to create synthetic tokens. - -Token Sponsors deposit collateral into the contract to collateralize synthetic tokens, which they can then withdraw -and trade with others. The first token sponsor to create synthetic tokens is able to immediately withdraw synthetic tokens -from the contract. Any following token sponsors must collateralize their positions by at least as much as the system’s -average collateralization ratio among all token sponsor positions that have not been liquidated (“GCR," or global -collateralization ratio). Requiring new token sponsors to collateralize their positions by as much as the GCR provides -some assurances that so long as those token sponsors collateralized below the GCR have not yet been liquidated, those -above the GCR need not be at risk of liquidation. - -## Managing Token Sponsor Positions - -Token sponsors can deposit additional collateral at any time. Token sponsors can withdraw excess collateral in one of two ways: a “fast” withdrawal or “slow” withdrawal. - -### “Fast” withdrawal: - -A “fast” withdrawal allows a token sponsor to withdraw excess collateral from his position immediately, so long as the resulting position is collateralized by at least as much as the global collateralization ratio (GCR). -Requiring withdrawals to result in collateralization at least as high as the GCR provides some assurances that so long as the other token sponsors collateralized below the GCR have not yet been liquidated, this token sponsor should not be liquidated after making this withdrawal. - -### “Slow” withdrawal: - -If the token sponsor wishes to withdraw collateral from his position that would bring his collateralization below the -global collateralization ratio, he can do so via a “slow” withdrawal. Because withdrawing this amount of collateral -could potentially jeopardize the solvency of the fungible synthetic tokens, this “slow”, 2-part, withdrawal process -allows other token holders to flag if a withdrawal would render the token sponsor insolvent. - -In a “slow” withdrawal, there are two parts: The token sponsor submits a withdrawal request to the contract indicating the amount of collateral he wishes to withdraw and the timestamp of the request. - -During this period, any token holder can liquidate the token sponsor’s position if they believe a withdrawal of the amount -indicated in the withdrawal request would bring the token sponsor’s collateralization below the “collateralization -requirement” at the time of liquidation. If the “withdrawal liveness period” of 2 hours passes without a token holder -liquidating the token sponsor, the token sponsor may withdraw collateral from his position up to the amount requested. - -## Liquidation and Dispute - -At any time, a token holder may liquidate a token sponsor’s position. Liquidations happen immediately without calling -the oracle. Anyone may dispute a liquidation within the “liquidation liveness period” of 2 hours. - -To liquidate a token sponsor position, a token holder submits tokens to the contract and posts a liquidation bond. -The liquidation bond covers the cost of calling the DVM if the liquidation is disputed. -If the liquidation is not disputed, the liquidation bond is returned to the liquidator. -The tokens are submitted for 3 purposes: to indicate the size of the position to be liquidated, to close the token sponsor’s position, and to attest to the liquidator’s belief that the token sponsor’s position should be liquidated. -The liquidator will lose a portion of the collateral corresponding to the tokens if their liquidation is disputed and found to be invalid. - -Here are three ways in which a liquidation can be resolved: - -1. No one disputes the liquidation during the liquidation liveness period. -After the liquidation liveness period ends, collateral deposited by the token sponsor is returned to the liquidator, proportional to the number of synthetic tokens the liquidator has submitted in liquidation. - -2. Someone disputes the liquidation during the liquidation liveness period. -To do this, the disputer must post a bond. Once the dispute is raised, a price request is made to the UMA DVM. -This price request will return the value of the price identifier at the time of the liquidation, which will determine if the token sponsor was undercollateralized and resolve the "dispute". - -2a. If the price returned by the DVM indicates that the token sponsor was undercollateralized at the time of the liquidation: -- The disputer will lose their bond. -- The liquidator will receive all of the token sponsor position’s collateral. -- The token sponsor will not receive any of the collateral they have previously deposited into the position. - -2b. If the price returned by the DVM indicates that the token sponsor was not undercollateralized at the time of the liquidation: -- The disputer will receive back their dispute bond and a dispute reward. -- The liquidator will receive collateral equalling: (i) the value of the token at the time of liquidation as determined by the DVM, less (ii) the dispute reward paid to the disputer, less (iii) the improper liquidation reward paid to the original token sponsor. -- The token sponsor will receive any remaining collateral and a reward for the improper liquidation. - -## Redeeming Tokens - -Before the expiration date of the token, tokens may only be redeemed by token sponsors. -A token sponsor redeems a token by submitting it to the contract to be burned and receiving collateral proportional to the total amount of collateral that the token sponsor has deposited to the contract. - -## Redeeming After Expiry - -After the expiration timestamp for the synthetic tokens, anyone may settle the contract. -This calls on the UMA DVM to return the value of the token’s price identifier at the expiration timestamp. - -After this value is returned to the contract and the contract is settled, any token holder can redeem the tokens against the contract. -Redemption of the tokens returns the token holder collateral equal to the price identifier value returned by the UMA DVM. Sponsors may also withdraw any excess collateral from the contract after settlement. - -Additional details can be found [here](https://docs.umaproject.org/uma/synthetic_tokens/explainer.html). - -# Rationale - -Please see the individual PRs for the rationale behind each PR. - -# Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/core/contracts/financial-templates/implementation). -The directory contains both the [implementation](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/implementation/ExpiringMultiParty.sol) of the `ExpiringMultiParty` template and the [deployer contract](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/implementation/ExpiringMultiPartyCreator.sol) that will be registered with the DVM to allow users to deploy their own `ExpiringMultiParty` contract. - -# Security considerations - -Please see the individual PRs for details on how each affects the security of the UMA ecosystem. This repo has been audited by OpenZeppelin, and the final audit report will be made available [here](https://docs.umaproject.org/uma/index.html). - -Anyone deploying a new priceless token contract should take care to parameterize the contract appropriately to avoid the -loss of funds for users. Additionally, the contract deployer should ensure that there is a network of liquidators and -disputers ready to perform the services necessary to keep the contract solvent. Anyone planning to use a synthetic token -(as a sponsor or tokenholder) should validate that the token is solvent and well-parameterized before using since there are -configurations and states that make the proposed contract unsafe. - -If approved, this would be the first contract factory registered with the DVM on mainnet. Although extensive security -reviews indicate that the factory contract poses no threat to ecosystem security, registration should be provisional and -usage should be limited. $UMA-holders should evaluate the health and solvency of token contracts deployed from this factory -contract and contemplate de-registering this factory if contract security holes are identified, or if the aggregate amount -of user funds at risk in token contracts deployed from this factory exceeds 1M dai before July 1, 2020. However, the ultimate -responsibility for ensuring user safety is the users themselves and $UMA holders are not expected to safeguard the -circumstances around every token contract deployed from this factory, such as third party promotional efforts, contract -parameterization, user knowledge, etc. - -It is suggested that additional identifiers not be registered for use with this token factory until a solvent and functioning -synthetic token contract is on mainnet for at least 30 days. diff --git a/research/uma/umips/umip-40.md b/research/uma/umips/umip-40.md deleted file mode 100644 index 9d6552c1..00000000 --- a/research/uma/umips/umip-40.md +++ /dev/null @@ -1,200 +0,0 @@ -## HEADERS -| UMIP-40 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add BTC-BASIS-3M/USDC, BTC-BASIS-6M/USDC, ETH-BASIS-3M/USDC, ETH-BASIS-6M/USDC as price identifiers | -| Authors | Bae (bae@youmychicfila.com), K (k@youmychicfila.com) | -| Status | Approved | -| Created | January 18, 2020 | - -# SUMMARY - -The DVM should support price requests for both BTC-BASIS-3M/USDC, BTC-BASIS-6M/USDC, ETH-BASIS-3M/USDC, ETH-BASIS-6M/USDC price indices.

What are the financial positions enabled by creating this synthetic that do not already exist? - - Currently there does not exist an on-chain product on Ethereum that enables folks to deploy risk capital on the futures term structure on either BTC or ETH. Basis (difference between futures and spot) is a heavily popular product suite in the CeFi ecosystem that has nearly ~300mil+ ADV (average _daily_ volume) in this regime allocated to it, and with the rise of interest rate products on-chain, basis synthetics would be heavily useful for folks speculating on the steepening or flattening of the interest rate curve for BTC and ETH. - -2. Please provide an example of a person interacting with a contract that uses this price identifier. - - If Alice thought that the term structure on BTC or ETH was rich, then she could sell ("flattener") BTC/ETH-BASIS-3M/6M on AMM pools that it exists on. If Alice thought that the term structure on BTC or ETH was cheap, then should buy ("steepener") BTC/ETH-BASIS-3M/6M on AMM pools that it exists on. If Bob thought that there's a contentious ETH fork that'd split hash appropriately and give value to both forks, then a short-basis positions would create an accretive value position for Bob as the utility of the spot would outpace the futures (depending on how CeFi exchanges resolved indices, but usually they pick a fork), and in this case could sell ETH-BASIS-3M/6M. If Bob thought that the 3m-6m basis is rich or cheap, then he could buy or sell a combination of 3m and 6m synths appropriately. Essentially, folks can express a supply/demand crunch for BTC or ETH in terms of the basis. - -3. Consider adding market data - -While there does not exist a liquid proxy for basis, one could attribute the absence of the ~40%+ APY on the front end of the curve prevalent in alt futures in '17/'18 to the rise of the hedgers / speculators on basis in '19/'20, where the monthly volumes on basis portfolios vastly exceeds most TVLs of any DeFi product. - -# MARKETS & DATA SOURCES - - **Required questions** - -1.

- -# RATIONALE - -- Why this implementation of the identifier as opposed to other implementation designs? - -This question can be answered three-fold: 1) the choice of BTC and ETH for the basis was chosen as they are currently the two highest market cap coins with the most liquid futures markets. In the future, we plan to add others as well. 2) the maturity of the basis was chosen to be the two closest maturities (3m - March and 6m- June) as they are the most liquid / highest ADV 3) the choice of the 3 exchanges is explained below, but essentially they are 3 out of the 4 top exchanges globally for ADV/liquidity/reputation. - -- What is the reasoning for min + max bounds on the px identifier? - -Per some of the feedback, CeFi exchanges already have clamps around their swap funding rates to mitigate a persistent dislocation, and based on empirical analysis the +-25% bounds on the basis for both BTC and ETH seemed more than generous, and adds to the economic security around the synthetics to ensure sponsors do not get liquidated in a way that is not consistent with the term structure itself. - -- What analysis can you provide on where to get the most robust prices? (Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges) - -As mentioned in the initial section, Binance, Okex, and FTX are 3 out of the 4 most liquid / highest ADV exchanges in the world for derivatives and spot markets and reputed to be of extremely high quality with low probability of the exchange defaulting. The last few months, Binance regularly has had higher than 20 bil ADV, Okex >10bil, and FTX > 2bil. The wide consensus is that the BTC futures, ETH futures, BTC spot, and ETH spot are of the highest legitimate liquidity/volume + minimal price discrepancies from other exchanges. - -- What is the potential for the price to be manipulated on the chosen exchanges? - -Extremely low. Even to move the BTC or ETH spot/futures markets a percent, it'd require more than a few dozen million given the efficiency of the liquidity provision on these exchanges. Even in cascading liquidations on the future market, the basis has historically held up strongly given the liquidity on the spot and futures markets. - -- Should the prices have any processing (e.g., TWAP)? - -Not required to have a TWAP/VWAP/etc. - -

For BTC spot prices, the median of the prices from the 3 spot exchanges should be used. Same for ETH. - - As an example, for BTC-BASIS-3M, the formula is min(max(100.0 * [1 + (F-S)/S], 75.0), 125.0), where F would be a median of the 3 futures prices as mentioned above and S would be a median as well of the 3 spot prices, and the result would be rounded to 6 decimals. - -
- -# Security considerations - -**Example questions** - -1. Where could manipulation occur? - -As discussed in the `What is the potential for the price to be manipulated on the chosen exchanges?`, manipulation could occur at either at the spot layer or the futures layer on each of the each of the aforementioned exchanges. To disrupt BTC or ETH spot of futures on the biggest exchanges globally would require capital at the highest scale, and the dislocation, were it to be caused, would be short-dated due to the efficiency of those markets. - -Further, towards expiration, the front-month futures will become less liquid and easier to manipulate in terms of required capital. As such, we will ensure that the expiration of the synths using these price identifiers will expire a week _before_ any of the constituent futures in the basket expire. This way, we will minimize this attack vector. - -Lastly, as a form of manipulation resistance, per some of the feedback, CeFi exchanges already have clamps around their swap funding rates to mitigate a persistent dislocation, and based on empirical analysis the +-25% bounds on the basis for both BTC and ETH seemed more than generous, and adds to the economic security around the synthetics to ensure sponsors do not get liquidated in a way that is not consistent with the term structure itself. - -2. How could this price ID be exploited? - -Mentioned above. - -3. Do the instructions for determining the price provide people with enough certainty? - -Yes. - -4. What are current or future concern possibilities with the way the price identifier is defined? - -When the 3m and 6m expire, we'd have to recreate another set of price identifiers to encode maturity into the price identifier. However, when I spoke to Matt recently, I understand that there are upcoming DVM upgrades that'd enable passing in additional state so as to not create price identifier bloat, or in this case, recreating one every time there is a new future. - -5. Are there any concerns around if the price identifier implementation is deterministic? - -No. diff --git a/research/uma/umips/umip-41.md b/research/uma/umips/umip-41.md deleted file mode 100644 index c19b6605..00000000 --- a/research/uma/umips/umip-41.md +++ /dev/null @@ -1,105 +0,0 @@ -## Headers -| UMIP 41 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add uVOL-BTC-APR21 as a price identifier | -| Authors | Sean Brown (smb2796), Kevin Chan (kevin-uma), Tom Ibold (Tommy1231232) | -| Status | Approved | -| Created | January 25, 2021 -| [Discourse Link](https://discourse.umaproject.org/t/adding-volbtc-as-a-price-identifier/83 ) | - -## SUMMARY - -The DVM should support price requests for the 30-day daily volatility of BTC/USD. - -## MOTIVATION - -The DVM currently does not support the 30-day day volatility of BTC/USD. - -The volatility of Bitcoin is a major focus in the crypto and traditional finance world. Will the recent high volatility in Bitcoin continue throughout the year? Is Bitcoin too volatile to be considered a viable currency or safe haven asset? Whether volatility is considered high or low or where it will be in the future is always a debate. - -In traditional finance there are several ways to express your view on the volatility of an asset. Most options traders would reflect this opinion on an asset by buying or selling options and delta hedging. This effectively neutralizes the price movement of the asset and isolates the value of the option. However, for an average trader this may be complex, costly and requires a lot of maintenance of the position. An easier way to reflect this view is through a futures contract on a volatility index. The most popular index is the VIX which is a volatility index on the S&P 500 that derives its value from a basket of index options. The centralized exchanges in the crypto world are borrowing this concept to create similar ways for users to trade the volatility of Bitcoin. For example, FTX designed BVOL tokens which use a basket of their MOVE contracts to effectively create a volatility index in a similar way. This requires a consistently deep and liquid options market which proves to be a challenge in crypto especially in the decentralized finance space. - -With the uVOL-BTC price identifier we can create a simple volatility index that can be used to create tokens with the EMP contract to speculate on the volatility of BTC/USD in a decentralized way. - -## MARKETS & DATA SOURCES - -- Markets: Binance, Coinbase Pro, Bitstamp -- Pairs: BTC/USD for Coinbase Pro and Bitstamp, BTC/USDT for Binance -- Live Price Endpoints - -Not applicable for the volatility data given that it only needs to be calculated at expiry using the historical endpoints listed below. - -Uniswap data is on-chain and can easily be queried in real-time.

No. -- If there is a free tier available, how many queries does it allow for? Range of 20,000-30,000. -- What would be the cost of sending 15,000 queries? Covered by the initial free tier allowance, but ~$5 after that has been used. - -## PRICE FEED IMPLEMENTATION -For the creation of a BTC/USD volatility token, it is desired that the DVM return either the 30-day daily realized volatility of BTC/USD, or a 2-hour TWAP on the market price of uVOL-BTC. The type of price that the DVM will return is dependent on the timestamp the price request is made at. `1619827200` is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the 30-day daily realized volatility of BTC/USD calculation is used at expiry. This is very similar to the uGAS token and this design is outlined in [UMIP 22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md). - -This means that only the Uniswap TWAP calculation will need to be queried in real-time. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. - -## TECHNICAL SPECIFICATIONS -- Price Identifier Name: uVOL-BTC-APR21 -- Base Currency: uVOL-BTC-APR21 -- Quote currency: None. This is an index, but will be used with USDC. -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE -The uVOL-BTC token is an expiring token that settles at the end of a month with the prior 30-day realized daily volatility in annualized terms. This is different from centralized and traditional volatility indices that use implied volatility of options and prices of other options like securities to derive an index of expected volatility. The use of realized volatility in this design is very similar to a [volatility swap](https://www.investopedia.com/terms/v/volatilityswap.asp) in traditional finance. We believe this will be a simple and transparent way for crypto users to trade the volatility of an asset like Bitcoin in a decentralized way. UMA token holders can easily calculate or verify the settlement price by using just their browser and a spreadsheet. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because a synthetic token, that is trading based on the future price of an underlying index, will have its price affected by expectations of the future movement of the underlying. If there is a large discrepancy in the synthetic’s price and the underlying index, arbitrageurs could take advantage of the difference in price by minting tokens at a rate determined by the underlying, abandoning their collateral to be liquidated and selling the tokens at the higher trading rate. Additionally, if a token is trading at a price that is higher than the notional value of the backing collateral, there would be no economic incentive for a liquidator to perform a liquidation. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -## IMPLEMENTATION -Voters should determine which pricing implementation to use depending on when the price request was submitted. - -**At Expiry** -If the price request's UTC timestamp is at or after 1619827200 (May 1, 2021 @ 12:00AM UTC), a price request uVOL-BTC for a given timestamp should be determined by performing the below for each data source (Coinbase Pro, Binance and Bitstamp): -1. Query the daily price of BTC/USD(T) over the previous 31 days before the given timestamp (1619827200) from each market. This can be queried for each day using the historical endpoints provided. -2. Calculate the percentage change between each day over the 30-day time period independently for each market. The daily percentage change is calculated in this way: [Close Price/Open Price - 1]. -3. Take the standard deviation of this 30 observation data set. This can be done using a spreadsheet function such as [STDEV](https://support.google.com/docs/answer/3094054?hl=en) in Google Sheets or one can manually [calculate](https://www.investopedia.com/terms/s/standarddeviation.asp) this. The result is the standard deviation of a daily move and should be done independently for each market. -4. Multiply each market's standard deviation by the square root of 365 to annualize the result. -5. Finally, multiply the three results by 100 to produce the index value. -6. Take the median of the Coinbase Pro, Binance and Bitstamp results from step 5. -7. Round the median to 6 decimal places. - -An example of a hypothetical uVOL-BTC-DEC20 settle is illustrated in [this](https://docs.google.com/spreadsheets/d/1PJDithMqoCY4Y5ANPw0KPW6q8kPj2O62L8gflCkZ2OA/edit#gid=599037359) Google Sheet. - -**Before Expiry** -If the price request's UTC timestamp is less than 1619827200 (May 1, 2021 @ 12:00AM UTC), voters will need to calculate a 2-hour TWAP for the uVOL-BTC-APR21 token's price in USDC. The following process should be used to calculate the TWAP. -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the uVOL-BTC-APR21 / USDC pool returns in the latest block where the block timestamp is <= the price request timestamp. This is the price of 1 uVOL-BTC-APR21 token in USDC. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. This should then be rounded to 6 decimals. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -## Security Considerations -Security considerations are focused on the use of the token price for monitoring collateral ratios. -- Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -- Mismatch between TWAP and gap higher in token price - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations - as the 30-day realized daily volatility of BTC/USD should be slow moving by design - or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uVOL-BTC, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -Security considerations, like the ones above, have been contemplated and addressed, but there is potential for security holes to emerge due to the novelty of this price identifier. - -Additionally, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Contract deployers should also ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier or editing its implementation if security holes are identified. diff --git a/research/uma/umips/umip-42.md b/research/uma/umips/umip-42.md deleted file mode 100644 index 5cae8ad0..00000000 --- a/research/uma/umips/umip-42.md +++ /dev/null @@ -1,41 +0,0 @@ -## Headers -| UMIP-42 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add renDOGE as a collateral currency | -| Authors | Logan Fulcher (logan@opendao.io) | -| Status | Approved | -| Created | January 20,2021 | -| Link to Discourse | https://discourse.umaproject.org/t/adding-rendoge-as-collateral-umip/24/30 | - -## Summary (2-5 sentences) -This UMIP should add renDOGE to the supported collateral currencies into the global whitelist contract, allowing for the usage of renDOGE as collateral currency. - -## Motivation -Dogecoin is a derivative of Luckycoin which forked from Litecoin and uses a Scrypt algorithm. It has been a presence in the crypto currency community since 2013, and despite its reputation as "only a meme coin," dogecoin sees ongoing mining and significant trade volume, particularly among the Litecoin mining community and its highly dedicated meme fan base. DOGE has a current market capitalization of $1.17 billion & 24 hour trading volume of approximately $256 million. The coin has maintained a top 100 position in market cap for nearly 8 years. - -renDOGE is an ERC20 variant of DOGE and is the catalyst for the process of incorporating DOGE into decentralized finance. renDOGE is similar to renBTC, in that the DOGE is custodied in a permissionless manner by Ren.

The process utilizes RenVM via OpenDAO to convert DOGE to renDOGE, then mint a stablecoin backed by DOGE ($DOGEO) as collateral, which is built on UMA. - -In process, renDOGE holders would supply tokens to the OpenDAO Platform as a collateral asset to mint DOGEO via underlying UMA contracts; the newly minted DOGEO, being a synthetic asset that traces the value of USD, could then be used elsewhere or converted into another stablecoin for a variety of purposes. Once users of the DOGEO token want their locked renDOGE collateral back, they would bring DOGEO back to the OpenDAO platform, settle any fees/interest, and then reclaim their renDOGE tokens which can be converted back into the original DOGE. A DOGEO/USDC pool will be created via Uniswap for easy access into other markets using DOGEO. It is also possible that DOGEO may find itself available for use in other future applications as well. - -## Technical Specification -To accomplish this upgrade, two changes need to be made: -- The renDOGE address, [0x3832d2F059E55934220881F831bE501D180671A7](https://etherscan.io/address/0x3832d2F059E55934220881F831bE501D180671A7#readProxyContract), needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 11,000 renDOGE needs to be added for the renDOGE in the Store contract. - -## Rationale -​ -The rationale behind this change is that it fits into a larger goal of furthering adoption of the UMA protocol by allowing renDOGE to be used as collateral, whereas DOGE's wide user base, which currently lacks yet shows interest in defi integration, can leverage the UMA protocol. Other projects are currently working towards this goal as well. Major community members in the DOGE community, along with commercial enterprises, have already shown interest in our efforts. UMA is the best choice for furthering this endeavor, as the security, service, team, and reputation provided by UMA are certain to make these efforts successful and secure. - -The addition of renDOGE serves UMA, OpenDAO, Ren, their respective communities and members, the Dogecoin community, and the larger crypto and defi industries at large. - -## Implementation -​ -This change has no implementation other than the changes listed in the *Technical Specification* section. - -## Security Considerations -​ -renDOGE has several security considerations that have been taken in to account and discussed at length by the UMA community (available here: https://discourse.umaproject.org/t/adding-rendoge-as-collateral-umip/24/32). Major concerns included, liquidity and its stability, unusually high volatility, and peg detachment. Since the initial submission of this umip, we have seen both the demand and the volume of renDOGE increase dramatically, and with continued growth, we expect the necessary volume and liquidity required for security to be met; SushiSwap just added the renDOGE-WETH pair to Onsen and we are seeing more projects creating utility. The token is also gravitating more tightly towards its peg, and the overall outlook for renDOGE is positive. However, due to the novelty of the renDOGE token, and the unusually high volatility of the underlying DOGE collateral, it is recommended that the collateralization factor for renDOGE be increased to 3x-5x, as deemed appopriate by UMA. Additionally, it is suggested that voting time extensions beyond the typical duration be considered to prepare for counteracting periods of low lqiuidity. - -Additionally, it is important to note that renDOGE will likely be approximately 0.1% lower in price than DOGE, due to the 0.1% fee involved with going from renDOGE to DOGE, however, we don't expect this to greatly impact security. diff --git a/research/uma/umips/umip-43.md b/research/uma/umips/umip-43.md deleted file mode 100644 index 5431ce79..00000000 --- a/research/uma/umips/umip-43.md +++ /dev/null @@ -1,39 +0,0 @@ -# Headers -| UMIP-43 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add Ocean as a collateral currency | -| Authors | Logan (logan@opendao.io) | -| Status | Approved | -| Created | January 28, 2021 | -| Created | January 28, 2021 | -|Link to Discourse| https://discourse.umaproject.org/t/adding-ocean-as-collateral-umip/117 | - -## Summary (2-5 sentences) -This UMIP will add Ocean to the supported collateral currencies on the global whitelist contract, allowing the usage of Ocean as collateral currency. - -## Motivation -The motivation of adding Ocean as a supported collateral in the global whitelist contract is so that Ocean holders can go long on Ocean by minting a stablecoin backed by Ocean as collateral, which will be built on UMA. - -The Ocean token is used to stake on data, to govern Ocean community funding, and to buy & sell data.

Each WBTC is backed 1:1 with Bitcoin. Wrapped Bitcoin allows for Bitcoin transfers to be conducted quicker on the Ethereum blockchain and opens up the possibility for BTC to be used in the decentralized finance ecosystem. The Bitcoin collateral is held in custody by the centralized custodian, BitGo. Bitcoin can be converted to Wrapped Bitcoin and vice versa quite easily. - -At the time of writing, WBTC is trading at $33,767.47 with a 24-hour trading volume of $346,285,873.

NA -- What would be the cost of sending 15,000 queries? $0. - -## PRICE FEED IMPLEMENTATION -For the creation of the uSTONKS token, it is desired that the DVM return either the final closing index value of uSTONKS, or a 2-hour TWAP on the market price of uSTONKS_APR21. The type of price that the DVM will return is dependent on the timestamp the price request is made at. This timestamp is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the closing index value of uSTONKS calculation is used at expiry. This is very similar to the uGAS token and this design is outlined in [UMIP 22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md). - -Because the uSTONKS index value is only used at expiry, it will not be possible for a token sponsor to become undercollateralized based upon its movement. This means that only the Uniswap TWAP will need to be queried in real-time with a price feed. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. - -## TECHNICAL SPECIFICATIONS -- Price Identifier Name: uSTONKS_APR21 -- Base Currency: uSTONKS_APR21 -- Quote currency: None. This is an index, but will be used with USDC. -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE -The uSTONKS token is an expiring token that settles at the end of the expiry month using the final exchange closing prices on the last business day of the month for the ten stocks in the basket. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because uSTONKS is a decentralized synthetic that trades continuously 24/7 whereas the underlying stocks in the uSTONKS index trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. Using price feeds from the exchanges to monitor collateral ratios of token sponsors could be problematic outside of market hours especially if there is significant news released or general macro market forces. Though some stocks are traded after hours, the ability to extract this price data is difficult and the frequency may not be consistent across all ten stocks. Therefore, using the uSTONKS token price itself to monitor collateral ratios is a much better alternative as it should reflect the actual price movements during exchange hours and also reflect expectations of price movements after market hours. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -The stocks chosen represent the stocks with the highest average comment volume on r/WallStreetBets. This index was picked on January 29th, 2021 using r/WallStreetBets comment analysis from swaggystocks.com, and will remain static throughout the life of the price identifier. - -## IMPLEMENTATION -Voters should determine which pricing implementation to use depending on when the price request was submitted. - -**At Expiry** - -If the price request's UTC timestamp is at 1619812800 (April 30, 2021 @ 4:00PM EST), a price request for uSTONKS for a given timestamp should be determined by performing the `At Expiry` process. - -To create a baseline for the uSTONKS index, a base price for each stock was chosen. These prices are the closing prices of each on 12/31/2020 and can be used by voters as reference values for their calculations. Voters are highly encouraged to verify these values themselves. This basket is static - it will not change over the life of the contract. - -| Ticker | Stock Price 12/31/2020 | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| GME | 18.84 | -| AMC | 2.12 | -| NOK | 3.91 | -| BB | 6.63 | -| SLV | 24.57 | -| TSLA | 705.67 | -| PLTR | 23.55 | -| SNDL | 0.47 | -| AAPL | 132.69 | -| SPCE | 23.73 | - -Each stock also is assigned an index value base. The index is equally weighted, so each stock is assigned a base of 10. This means that on 12/31/2020 at close, the uSTONKS index would have been worth 100 with every component making up 1/10th of that index. - -To calculate the uSTONKS price, an UMA voter should: -1. Query for the close price of one component on March 31, 2021. It is recommended that voters use the Google Sheets GOOGLEFINANCE function. -2. Divide the March 31 price by the base price and multiply by the index value base (10) to get today’s index value. -3. Perform this function for each component in the index and sum all of the results together. -4. Round the result of step three to six decimal places - -An example of this calculation is shown in [this](https://docs.google.com/spreadsheets/d/1AtNzHvn_0na1miktsF2vmmB5fRj2_y793r-j7_m7P8M/edit?usp=sharing) Google Sheet. - -It is possible that, over the life of this price identifier, certain situations could arise that would affect the validity of the index calculation. Guidance is provided below for certain situations, but voters are free to come to an alternative consensus if a flaw in the methodology is identified or an unforeseen event occurs. - -1. In the case of a stock split, the base price of the stock should be divided by the number of shares that the stock is being split into. As an example - if AMC issued a 4:1 stock split, the base price of AMC, 2.12, would be divided by 4 and the new base index price would be 0.53. -2. In the case of a stock consolidation, the process is the same as for a stock split, except the base price should be multiplied by the number of shares being consolidated. - -**Before Expiry** - -If the price request's UTC timestamp is less than 1619812800 (April 30, 2021 @ 4:00PM EST), voters will need to calculate a 2-hour TWAP for the uSTONKS_APR21 token’s price in USDC. The following process should be used to calculate the TWAP. -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the uSTONKS_APR21 / USDC pool returns in the latest block where the block timestamp is <= the price request timestamp. This is the price of 1 uSTONKS_APR21 token in USDC. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. This results should be rounded to 6 decimals. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -## Security Considerations -Security considerations are focused on the use of the token price for monitoring collateral ratios. -- Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -- Mismatch between TWAP and gap higher in token price - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uSTONKS_APR21, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -Security considerations, like the ones above, have been contemplated and addressed, but there is potential for security holes to emerge due to the novelty of this price identifier. - -Additionally, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Contract deployers should also ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier or editing its implementation if security holes are identified. diff --git a/research/uma/umips/umip-48.md b/research/uma/umips/umip-48.md deleted file mode 100644 index ddd4f78f..00000000 --- a/research/uma/umips/umip-48.md +++ /dev/null @@ -1,61 +0,0 @@ -# Headers -| UMIP-48 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add GASETH_JUN21 as a supported price identifier | -| Authors | nonstopTheo (nonstoptheo@yam.finance) -| Status | Approved | -| Created | February 10th, 2021 | -| Link to Discourse| https://discourse.umaproject.org/t/umip-48-add-gaseth-jun21-as-a-supported-price-identifier/217 - -## SUMMARY -This UMIP will reference a synthetic token to be created with this price identifier.

Current liquidity is low, and cross-exchange price discrepancies are 5%+. Over time, as more $COMP supply becomes available, we anticipate that cross-exchange price discrepancies will be reduced. - -Opportunity: A synthetic token that tracks $COMP would enable better price discovery by making it possible to short $COMP. It could be used as a hedging tool. It also increases yield for $COMP holders (who could sell $COMP to buy synthetic $COMP when there are negative funding rates to do so). - -## Technical Specification - -The definition of this identifier should be: -- Identifier name: COMPUSD -- Base Currency: USD(T) -- Quote Currency: COMP -- Exchanges: Coinbase Pro (COMPUSD), Poloniex (COMPUSDT), FTX (COMPUSD) -- Result Processing: Median -- Input Processing: None.

Until the Coinbase Pro market officially goes live and starts trading, the technical specification of this identifier is to take the median of available exchanges (eg Poloniex COMPUSDT and FTX COMPUSD). Once Coinbase Pro is live and stable, the technical specification of this identifier will be the median across Coinbase Pro, Poloniex, and FTX. - -## Rationale -Prices are primarily used by Priceless contracts to calculate a synthetic token’s redemptive value in case of liquidation or expiration. Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. - -More complex computations (like incorporating additional exchanges, calculating a TWAP or VWAP, or imposing price bands, etc.) have the potential to add a greater level of precision and robustness to the definition of this identifier, particularly at settlement of each expiring synthetic token. However, we felt that the costs in increased complexity and mental load to the stakeholders who need to use it (like sponsors, liquidators, and disputers) outweighed the benefits, especially during this period where the $COMP token is newly launched and being listed on additional exchanges. - -Currently the only exchanges with USD or stablecoin markets for $COMP are Coinbase (as of Monday, June 22), FTX, and Poloniex. The price discrepancy across exchanges can be high since $COMP is a low liquidity token. Over time, as liquidity in the $COMP token migrates across platforms, this identifier can be re-defined to add exchanges, remove exchanges, or change the way that the price is calculated. Any re-definition would be done via off-chain social consensus by $UMA-holders, and ultimately reflected in the way that $UMA-holders vote upon the price of $COMPUSD when called to do so by disputers, or at settlement. - - -## Implementation - -The value of this identifier for a given timestamp should be determined by querying for the price of COMPUSD(T) from Coinbase, FTX, and Poloniex for that timestamp, taking the median, and determining whether that median differs from broad market consensus. This is meant to be vague as the $UMA tokenholders are responsible for defining broad market consensus. - -Ultimately, how one queries the exchanges should be varied and determined by the voter to ensure that there is no central point of failure. - -While it's important for tokenholders to have redundancy in their sources, bots and users that interact with the system in realtime need fast sources of price information. In these cases, it can be assumed that the exchange median is accurate enough. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/financial-templates-lib/price-feed/CryptoWatchPriceFeed.js) -is a reference implementation for an offchain price feed based on the -[CryptoWatch API](https://docs.cryptowat.ch/rest-api/).

More directly, this furthers adoption of the protocol by encouraging a convergence of capital from different projects and by potentially increasing TVL significantly. - -Currently the most liquid exchange with USD or stablecoin markets for WBTC is BKEX (17.7% volume) while most overall trade involving WBTC is on Uniswap (~30% volume). BKEX will not be used for defining the price ID, as it is not available through Cryptowatch; however, due to the large volume and high liquidity of WBTC, it should be acceptable to use other markets, even if less voluminous. WBTC can currently be traded on a wide variety of exchanges, including what are widely considered to be several top tier platforms. - -In the current setting, there will need to be a significant event that erodes confidence in WBTC and the token for it to be a security or PR concern. - -A 1 minute TWAP is being used when querying for DEX prices to prevent any attempted price manipulation on the pools. - -## Implementation - -Voters should use the following process to determine the WBTCUSD and USDWBTC prices. -1. The WBTCBTC rate from Binance should be queried. The price at the timestamp that is closest but earlier than the price request timestamp should be used. -2. Using the implementation defined in UMIP-7, voters should query for the BTCUSD rate at the price request timestamp. -3. The results of steps 2 and 3 should be multiplied to return the Binance WBTC/USD price. -4. The Sushiswap and Uniswap WBTC/ETH prices should be queried for the block that is closest but earlier than the price request timestamp. This block should be used as the end bound for a one minute TWAP on both the Sushiswap and Uniswap prices. -5. Using the implementation defined in UMIP-6, voters should query for the ETHUSD rate at the price request timestamp. -6. The Sushiswap WBTC/ETH rate should be multiplied by ETHUSD to return the Sushiswap WBTC/USD price. -7. The Uniswap WBTC/ETH rate should be multiplied by ETHUSD to return the Uniswap WBTC/USD price. -8. The median of results of steps 3, 6 and 7 should be taken and rounded to 6 decimals to return the WBTCUSD price. - -The USDWBTC price follows the same process but just adds an additional step before rounding. The inverse of the WBTCUSD median should be taken (1/WBTCUSD) and rounded to 8 decimals to return the USDWBTC price. - -## Security considerations - -WBTC is centralized in that the BTC collateral is custodied by BitGo and thus presents a central source of potential failure that should be considered; in light of this, it is important to note that BitGo is one of the most reputable centralized custodians in the world and has highly advanced coin security protocols in place. Furthermore, BitGo is covered by digital asset insurance worth up to $100 million in the worst case scenario. - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. diff --git a/research/uma/umips/umip-52.md b/research/uma/umips/umip-52.md deleted file mode 100644 index 22b0df55..00000000 --- a/research/uma/umips/umip-52.md +++ /dev/null @@ -1,43 +0,0 @@ -## Headers -| UMIP-52 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add Optimistic Oracle | -| Authors | John Shutt (john@umaproject.org) | -| Status | Approved | -| Created | February 16, 2021 | - -## Summary (2-5 sentences) -This UMIP will have the effect of introducing a new optimistic oracle contract that will allow optimistic settlement of prices and funding rates without a vote from the DVM.

This upgrade -will allow price requests to include a data blob of arbitrary length (up to 8192 bytes) to provide additional arguments -or data for the price resolution process. - -## Motivation & Rationale - -Governance votes are extremely common and fairly costly. The largest contributor to governance votes is the requirement -for any contract that wants to track a new asset to have a new identifier approved for that asset. This means the -developer who's deploying this contract must write a new UMIP, the team must review, and all voters must submit votes -to approve the new identifier. That's a lot of effort considering most price identifiers are not controversial, and -their prices are often pulled from the similar sources as existing price identifiers. - -A similar issue is presented when contracts want the DVM to provide more arbitrary computation. One could imagine -options contracts that need to have identifiers that return prices based on the option expiry and the strike price -in addition to the timestamp of the price request. Right now, the DVM only allows users to pass in a single timestamp -to note the time at which the price was requested. Unless a new identifier were created for each expiry, strike price -combination, there is no way for the DVM to price something as complex as an option. There are other, more complex use -cases for the DVM performing "decentralized computation" rather than just looking up a price. - -The solution to these problems is giving deployers the ability to define price identifiers that take arbitrary -parameters. - -In the first example, users can create meta price identifiers that define the _types_ of prices that can -be requested. For instance, a price identifier could allow any asset listed on Uniswap, Sushiswap, Balancer, Binance, -Coinbase, FTX, Huobi, OKEX, or Kraken. The user could provide a list of exchanges and the way they're identified on -each exchange in the ancillary data, which could be decoded by voters and bots alike. - -In the second example, an option price identifier could be created and users could encode the expiry and strike price -in their ancillary data, which would give voters and bots the ability to compute the true price of any option without -needing many distinct identifiers. - -## Technical Specification - -This UMIP adds a Voting contract that is effectively identical to the previous Voting contract, except that most -methods now accept an additional `ancillaryData` argument.

Though, all else -equal, any improper collateralization caused would be handled the same as any other EMP contract: - - (i) a position sponsor can only immediately remove the amount of collateral that would keep their position above the GCR, - - (ii) if any sponsor attempts to perform a withdraw of their $UMA, they won't be able to use that $UMA to be able to influence any disputes regarding that position. - -Using UMA as collateral may also serve as a way to temporarily take $UMA tokens off the market without the effects of otherwise burning or selling the tokens. Storing UMA as collateral may also as another line of defense before performing a "buy-and-burn" operation to decrease circulating supply to thereby increase the Cost of Corruption. - -> For additional discussion, see also ["Should UMA be added on lending protocols" on Discourse][discourse-uma]. - - [discourse-uma]: https://discourse.umaproject.org/t/should-uma-be-added-on-lending-protocols/87/3 - ---- - -## UNI (Uniswap Token) - -### Motivation / Rationale - -Uniswap is one of the most popular and liquid decentralized exchanges on Ethereum. UNI is already ranked top 20 by cryptocurrency market capitalization. As one the most liquid ERC20 tokens on Ethereum, there is plenty of potential to utilize UNI as collateral within the UMA ecosystem. - -### Technical Specification - -To accomplish this upgrade, two changes need to be made: - * The UNI address, [0x1f9840a85d5af5bf1d1762f925bdaddc4201f984][uni], needs to be added to the collateral currency whitelist introduced in UMIP-8. - * A final fee of 20 UNI needs to be added for the UNI in the Store contract. (~$415 at time of writing) - - [uni]: https://etherscan.io/token/0x1f9840a85d5af5bf1d1762f925bdaddc4201f984 - -### Implementation - -These changes have no implementation other than adding the collateral types to the whitelist. - -
- -# Security Considerations -AAVE, LINK, SNX, UMA, and UNI have shown to be persistently valuable ERC20 tokens given their liquidity and top market capitalization, including them as collateral currencies should impose no additional risk to the protocol. - -The only security implication is for contract deployers and users who are considering using EMP contracts with AAVE, LINK, SNX, UMA, or UNI as the collateral currency. They should recognize that, relative to most fiat currencies, these assets are much more volatile. This volatility should be taken into account when parameterizing or using these EMP contracts. diff --git a/research/uma/umips/umip-57.md b/research/uma/umips/umip-57.md deleted file mode 100644 index eb188686..00000000 --- a/research/uma/umips/umip-57.md +++ /dev/null @@ -1,650 +0,0 @@ - **Headers** -| UMIP-57 | | -|------------|------| -| UMIP Title | Add price identifiers for AAVEUSD, USDAAVE; LINKUSD, USDLINK; SNXUSD, USDSNX; UMAUSD, USDUMA; UNIUSD, USDUNI | -| Authors | Josh Bowden (josh@ferrosync.io) | -| Status | Approved | -| Created | February 17th, 2021 | -| Discourse Link| -
- -# Overview -This proposal is for adding the following price identifiers to be supported: - - * AAVEUSD, USDAAVE - * LINKUSD, USDLINK - * SNXUSD, USDSNX - * UMAUSD, USDUMA - * UNIUSD, USDUNI - -# Motivation - -The purpose of adding these price identifiers is to be able to mint synthetic tokens priced at the defi protocol's token valued against USD. By doing so, users who mint synthetic tokens and sell them to the market are able to short the protocol. Similarly, users who buy the synthetic token are able to long the protocol. - -If the inverse price identifier is used (e.g. USD/UMA) and the same altcoin token is employed as collateral, then the value of the synthetic token can be traded in place of the underlying collateral without having to sell the underlying asset. - -# Rationale -For each altcoin token, we choose to have both `XYZUSD` and `USDXYZ` price identifiers (where the symbol `XYZ` is either `AAVE`, `LINK`, `SNX`, `UMA`, `UNI`) to allow for financial products that use either the altcoin token or stable USDC as collateral. - * Using USDC as collateral allows for speculating on the price of `XYZUSD` -- risking liquidation if the price of the altcoin increases relative to USD. - * Using the altcoin as collateral allows for borrowing synthetic USDC equivalents tracking `USDXYZ` -- risking liquidation if altcoin *decreases* in value relative to USD. - -We picked the top 3 exchanges by trading volume to avoid price movements solely to do poor liquidity. - -A time interval of 1 minute is the most granular time interval supported by the API. We choose a small time interval to ensure that positions track with any large price movements that may occur -- given that this may be a volatile instrument. - -We choose to use a median of three exchanges to balance the overhead of additionally required API calls for liquidation bots between an increased sample size of market prices. The median of the prices was choose instead of a simple arithmetic average to handle the scenarios where a given exchange is halted, unresponsive, or has erratic price movement. - -Quoted prices in USD are rounded to 6 amounts since (i) the USDC ERC20 contract only has 6 decimal places, and (ii) most exchanges only quote prices in USD between 2 to 6 decimal places. We've done the same (i.e. round to 6 decimal places) as well for all `USDXYZ` inverse price identifier for implementation and voting simplicity. - -

- -# Security Considerations -Adding these new identifiers by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing these identifiers should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for these identifiers and also contemplate de-registering these identifiers if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness is necessary to prevent market manipulation. diff --git a/research/uma/umips/umip-58.md b/research/uma/umips/umip-58.md deleted file mode 100644 index 86e0464d..00000000 --- a/research/uma/umips/umip-58.md +++ /dev/null @@ -1,74 +0,0 @@ -# Headers -| UMIP-58 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add UNI-V2 LP tokens WBTC-ETH, USDC-ETH, UNI-ETH, and UMA-ETH, as whitelisted collateral currencies | -| Authors | Dev-1 (dev-1-lp-dollar), Dev-2 (dev-2-lp-dollar) | -| Status | Approved | -| Created | February 09, 2021 | -| Link to Discourse | [Discourse](https://discourse.umaproject.org/t/add-uni-v2-wbtc-eth-as-a-supported-collateral-currency/149) | - -## Summary -This UMIP will add the following UNI-V2 LP tokens as approved collateral currencies: WBTC-ETH, USDC-ETH, UNI-ETH, and UMA-ETH. - -This will involve adding the currencies to the whitelist and adding a flat final fee to charge per-request.

All tokens are widely used across the cryptocurrency space, and account for a large amount of activity in the decentralized finance space. - -UNI-V2 LP tokens as a collateral type are expected to have a variety of deployments. They will open the door for the creation of synthetic assets with CFMM positions. - -## Technical Specification -To accomplish this upgrade, two changes need to be made for each UNI-V2 pair: - -*WBTC-ETH* -- The UNI-V2 WBTC-ETH LP address, 0xBb2b8038a1640196FbE3e38816F3e67Cba72D940, needs to be added to the collateral currency whitelist. -- A final fee of 0.0000002 needs to be added for UNI-V2 WBTC-ETH LP in the Store contract. - -*USDC-ETH* -- The UNI-V2 USDC-ETH LP address, 0xB4e16d0168e52d35CaCD2c6185b44281Ec28C9Dc, needs to be added to the collateral currency whitelist. -- A final fee of 0.0000035 needs to be added for UNI-V2 USDC-ETH LP in the Store contract. - -*UNI-ETH* -- The UNI-V2 UNI-ETH LP address, 0xd3d2E2692501A5c9Ca623199D38826e513033a17, needs to be added to the collateral currency whitelist. -- A final fee of 0.55 needs to be added for UNI-V2 UNI-ETH LP in the Store contract. - -*UMA-ETH* -- The UNI-V2 UMA-ETH LP address, 0x88D97d199b9ED37C29D846d00D443De980832a22, needs to be added to the collateral currency whitelist. -- A final fee of 0.8 needs to be added for UNI-V2 UMA-ETH LP in the Store contract. - - -## Rationale -The rationale behind this change is giving deployers more useful collateral currency options. This is an advancement into a better type of collateral. - -$400 USD equivalent was chosen as the final fee because it is equal to or above the mimimum of already approved coins. - -## Implementation - -This change has no implementation other than proposing the two aforementioned governance transactions that will be proposed. - -## Security Considerations -Since the underlying tokens are persistently valuable tokens, including the packaged version from the Uniswap product as supported collateral currencies should impose no additional risk to the protocol. - -The main implication is for contract deployers and users who are considering using contracts with these assets as the collateral currency. They should recognize and accept the volatility risk of using this, and ensure appropriate required collateralization rations (120%+), as well as a network of liquidator and support bots to ensure solvency. - -As mentioned above, the asset is packaged from Uniswap, a decentralized protocol on the Ethereum blockchain. Uniswap is one of the most popular, proven, and secure smart contract protocols to exist in decentralized finance and beyond. They've succesfully locked up and handled billions of dollars over the course of multiple years, with multiple extensive auditing from top names in the industry. There is the theoretical risk that the pools on Uniswap could be exploited and lead to a rapid loss of value in the currency proposed here which would require fast response to ensure solvency for any financial products built using this as a collateral type. However, due to the nature of Uniswap's long-proven track record around quality and security this is extremely unlikely. diff --git a/research/uma/umips/umip-59.md b/research/uma/umips/umip-59.md deleted file mode 100644 index 87f0f7e5..00000000 --- a/research/uma/umips/umip-59.md +++ /dev/null @@ -1,700 +0,0 @@ -## Headers -| UMIP-59 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add USD/UNI_V2_WBTC_ETH_LP, USD/UNI_V2_USDC_ETH_LP, USD/UNI_V2_UNI_ETH_LP, USD/UNI_V2_UMA_ETH_LP token price identifiers | -| Authors | Dev-1 (dev-1-lp-dollar), Dev-2 (dev-2-lp-dollar) | -| Status | Approved | -| Created | February 09, 2021 | -| Link to Discourse | [Discourse](https://discourse.umaproject.org/t/add-usd-uni-v2-wbtc-eth-as-a-price-identifier/148) | - -## Summary - -The DVM should support price requests for the following Uniswap V2 LP tokens: WBTC-ETH, USDC-ETH, UNI-ETH, UMA-ETH. - -## Motivation - -The DVM currently does not support Uniswap V2 LP tokens. - -By enabling LP token price identifiers, UMA will open the door for the creation of synths with CFMM (constant function market maker) LP positions. - -The price identifiers will enable fixed borrowing costs for Uniswap V2 liquidity providers (LPs) of WBTC-ETH, USDC-ETH, UNI-ETH, and UMA-ETH.

Including any Tether pair means the prices could change due to the price of Tether. However, we decided that these two factors sufficiently mitigate this risk: the purpose of the DVM is to give token holders leeway to evaluate events, such as this, and adjust the price response accordingly. This is adequately captured by the language "determining whether that median differs from broad market consensus." Second, the USDT price could only have the effect of pulling the median towards the higher or lower of the 2 USD pairs. Or, it could fall right in between them. For this reason we believe the USDT concern is sufficiently handled. - -We also considered an alternative set of exchanges.

- -# SUMMARY - -The DVM should support price requests for the below price indexes: -- DIGG/BTC -- DIGG/ETH -- DIGG/USD - -# MOTIVATION - -The DVM currently does not support the DIGG/BTC, DIGG/ETH or DIGG/USD price identifiers. - -DIGG is an elastic supply token pegged to the price of Bitcoin and governed by the Badger DAO. DIGG is currently pegged to 1 BTC, and uses a custom oracle to determine the necessary change in supply. If DIGG price is above 1.05 BTC, DIGG supply increases. This is known as a positive rebase. If DIGG price is below 0.95 BTC, DIGG supply decreases. This is known as a negative rebase. If DIGG price is between 0.95 and 1.05 BTC, DIGG does not rebase. Every DIGG holder gets the same increase or decrease in supply every rebase. - -Supporting the ability to obtain price exposure of DIGG against BTC, ETH, and USD would allow traders to hedge, speculate, and obtain long/short exposure while retaining WBTC or ETH exposure. Many users of these synthetic assets may be Badger yield farmers who want to hedge or arbitrage the DIGG rate. An example of someone who may want to use DIGGBTC would be when the DIGG price is higher than BTC and a trader has DIGG exposure earning a high annual yield along with the inflation rewards described above. Instead of selling DIGG, a user can hedge their DIGG exposure by keeping DIGG and separately using the UMA approved collateral types described in the Technical Specifications to mint DIGGBTC synthetic tokens and sell to the market. If the DIGGBTC rate decreases the user is able to buy DIGGBTC tokens back for less and receive their collateral at a lower DIGGBTC rate. In the opposite situation where DIGG is trading below the Bitcoin price, a DIGGBTC synthetic may be an attractive option for traders who believe the DIGGBTC rate will increase but do not want to be exposed to the daily rebases. - -In both of these situations the exchange rate of DIGG may be impacted by the rebases. However, the synthetic token only exposes the user to the price of DIGG against BTC/ETH/USD. The supply of the collateral used to mint the synthetic tokens (WBTC/USDC/WETH) and the synthetic tokens (DIGGBTC/DIGGETH/DIGGUSD) do not change based on the DIGG rebases. - -The Marketcap of DIGG is currently around $75 million. What makes synthetic DIGG interesting is the game theory behind DIGG, the volatility of both the BTC and DIGG prices, along with yield farmers being able to use these synthetics to hedge their DIGG exposure. - -

- -# RATIONALE - -**Why this implementation of the identifier as opposed to other implementation designs?** - -This implementation is due to DIGG's main sources of liquidity being on Sushiswap and Uniswap. Currently, only one low volume and low depth centralized exchange has DIGG listed, and most liquidity will remain on DEXs as it is incentivized. - -**What analysis can you provide on where to get the most robust prices? (Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges)** - -Sushiswap and Uniswap have the vast majority of DIGG volume and depth. These should be used over all other sources. - -**What is the potential for the price to be manipulated on the chosen exchanges?** - -DIGG is not a collateral on any loan services and the majority of the liquidity is locked into farming vaults. The potential risk for this is low. - -**Should the prices have any processing (e.g., TWAP)?** - -A 30 minute TWAP was chosen to help smooth out price changes and give sponsors time to react before becoming undercollateralized. A 30 minute TWAP will also mitigate risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. Another factor influencing the TWAP decision is the daily rebase and its potential impact on the supply and exchange rate which is described further in the Security Considerations section. - -A 24 hour TWAP was chosen for DIGGBTC to be applicable as a price oracle for DIGG rebases. - -
- -# IMPLEMENTATION - -For all implementations, a block number will need to be used. The block number should be the block that is closest to and before the timestamp that the price request timestamp. - -For DIGG/ETH and DIGG/USD TWAP implementations, the TWAP start time should be determined by the latest block 30 minutes before requested timestamp. For DIGG/BTC, it should be 24 hours before. When using DIGG/BTC in DIGG/ETH and DIGG/USD price calculations, a 30 minute TWAP should be used for DIGG/BTC. - -**For DIGG/WBTC** - - 1.

- -# Security considerations - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradeable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. - -DIGG Rebase - When the DIGG supply policy executes its rebase, all DIGG holders balances potentially increase or decrease together in a single transaction which include contracts that hold DIGG balances (Uniswap and Sushiswap). Since the DIGG reserve automatically adjusts, changing the relative size of the DIGG in pools, a new exchange rate is created. Having a 30 minute TWAP will allow the price to adjust after larger supply changes and prevent a higher risk of undercollateralized positions. - -Collateralization Requirements - All three of these identifiers are very volatile which brings on a higher risk of undercollateralized positions in the case of a massive DIGG price increase. Minimum collateral ratios should be higher compared with other price identifiers with ~1.5 being the minimum. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness are necessary to prevent market manipulation. diff --git a/research/uma/umips/umip-62.md b/research/uma/umips/umip-62.md deleted file mode 100644 index 5e58071c..00000000 --- a/research/uma/umips/umip-62.md +++ /dev/null @@ -1,179 +0,0 @@ -## Headers -| UMIP-62 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add ETHBTC_FR as a price identifier | -| Authors | Sean Brown (smb2796), Kevin Chan (kevin-uma) | -| Status | Approved | -| Created | Feb 24, 2021 -| [Discourse Link](https://discourse.umaproject.org/t/add-ethbtc-fr-as-a-supported-price-identifier/260) | - -## SUMMARY - -The DVM should support price requests for a funding rate for the ETH/BTC UMA perpetual. This funding rate represents the change in a synthetic token's value per second. - -*Note*: -This funding rate identifier requires querying for the price of the synthetic token that will be created by a contract using this identifier. Throughout this UMIP, this synthetic will be referred to as ETHBTC-PERP. Since this synthetic has not yet been created, its specific details can not yet be included. This UMIP will be updated once the ETHBTC-PERP has been created to include its address, token name and AMM pool address. - -## MOTIVATION - -Without an expiry date to keep a synthetic token pegged to its underlying price, UMA’s perpetual contract requires that a funding rate be levied when there is a difference between the synthetic’s price and the underlying index. This will pressure the overvalued side to unwind its position or encourage the undervalued side to create a larger position. This mechanic is similar to what centralized exchanges use to keep their perpetual synthetics in line with its underlier. - -Funding rate proposals and disputes function similarly to normal UMA price requests. On request, a proposer can post a bond and propose a new funding rate in return for a reward. If the funding rate proposal is not disputed within its liveness period, that proposed rate is then used to continuously adjust the value synthetic token sponsors' debt. If the proposed funding rate is successfully disputed, the proposer will lose their bond. The bond amount varies between each perpetual contract. - -It should be noted that this is an altered price reporting from what has been used historically by UMA contracts. With the introduction of the [Optimistic Oracle](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-52.md) and new [EMP](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-54.md) and [Perpetual contract](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-53.md) templates, all funding rate and settlement price requests will be handled by the Optimistic Oracle, and will only be sent to the voters of the DVM in the case of a price or funding rate dispute. - -*Note*: -For future funding rates, it is likely that a more generalized funding rate identifier should be created and used. A generalized funding rate identifier would be able to support any funding rate request by making use of [ancillary data](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-55.md#motivation--rationale). This UMIP is reduced in scope and specifically only creates a methodology for the ETHBTC funding rate and is being proposed so that this identifier can be used as an example of how a funding rate would work for a specific synthetic. - -## MARKETS & DATA SOURCES - -- Markets: - -Uniswap: ETHBTC_PERP/DAI -Coinbase Pro: ETH/BTC -Binance: ETH/BTC -Bitstamp: ETH/BTC - -- Live Price Endpoints - -Uniswap prices are on-chain and can be queried in a variety of methods. - -Coinbase Pro: https://api.cryptowat.ch/markets/coinbase-pro/ethbtc/price -Binance: https://api.cryptowat.ch/markets/binance/ethbtc/price -Bitstamp: https://api.cryptowat.ch/markets/bitstamp/ethbtc/price - -- Update time: - -Uniswap - every block. -Cryptowatch: Every 60 seconds - -- Historical Price Endpoints: - -Coinbase Pro: https://api.cryptowat.ch/markets/coinbase-pro/ethbtc/ohlc?after=1613450520&before=1613450520&periods=60 -Binance: https://api.cryptowat.ch/markets/binance/ethbtc/ohlc?after=1613450520&before=1613450520&periods=60 -Bitstamp: https://api.cryptowat.ch/markets/bitstamp/ethbtc/ohlc?after=1613450520&before=1613450520&periods=60 - -- Do these sources allow for querying up to 74 hours of historical data?

This funding rate will be used to keep the price of the ETHBTC-PERP synthetic pegged to the ETHBTC rate times the cumulative funding rate multiplier (CFRM). The funding rate will be determined with the following formula: -- [ETHBTC-PERP - ETHBTC-FV] / ETHBTC-FV / 86400 -- `ETHBTC-FV` denotes the ETHBTC price gathered with the methodology shown in [UMIP-2](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-2.md) multiplied by the CFRM. -- `ETHBTC-PERP` denotes the one hour TWAP of the synthetic created with this funding rate identifier. This synth will be pooled with DAI. -- 86400 is the number of seconds in a day. Assuming all other prices stay constant, this effectively gives the funding rate per second that would need to be applied to move a synthetic token's value back to fair value in one day. - -A one hour TWAP is used for the ETHBTC-PERP and ETHBTC-FV rates. This calculation was modeled off of the [FTX Funding rate calculation](https://help.ftx.com/hc/en-us/articles/360027946571-Funding), which also uses a 1-hour TWAP. - -86400 was chosen for two reasons. The current funding rate is continuously applied to sponsors' positions, so the proposed funding rate needs to be adjusted to a rate that reflects a continuous rate (per second rate). A day was chosen as the interval to move the fair value and perpetual price back to peg, because this follows existing and proven patterns created by CEX's like FTX. - -Min and max bounds of -0.00001 and 0.00001 were chosen because these are the funding rate calculations that represent a 100% drift of perp from peg. You can arrive at these amounts with 1/86400. - -## IMPLEMENTATION -To calculate the ETHBTC-FR, voters should use the following process: - -1. Following the specifications in [UMIP-2](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-2.md), query for the 1-hour ETHBTC TWAP, ending at the disputed funding rate proposal timestamp. This will consist of 60 queries for the close price of each 60 second ohlc period in that hour. Note that voters should calculate three separate 1-hour TWAPs, one for each exchange in UMIP-2, and then medianize these. -2. Query for the cumulative funding rate multiplier (CFRM) at the price request timestamp. -3. The 1-hour ETHBTC TWAP and the CFRM should then be multiplied - this result is referred to in future steps as ETHBTC-FV. -4. Query for the ETHBTC-PERP 1-hour TWAP from the listed AMM pool. This will return the ETHBTC-PERP's TWAP denominated in DAI. This rate should be left as is, with no conversion made between DAI and USD. -5. Subtract the result of step 4 from the result of step 3. [ETHBTC-FV - ETHBTC-PERP]. -6. Divide the result of step 5 by the ETHBTC-FV rate from step 4. [ETHBTC-FV - ETHBTC-PERP]/ETHBTC-FV. -7. Divide the result of step 6 by 86400 (# of seconds in a day) to get the funding rate per second. -8. Implement min and max bounds on this result with: max(-0.00001, min(0.00001, result)). -9. Voters should then round this result to 9 decimal places. - -As always, voters should determine whether the returned funding rate differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -### Cumulative Funding Rate Multiplier (CFRM) Calculation - -The contract specific CFRM is stored on-chain for each perpetual contract. Voters can query this on-chain data at the funding rate proposal timestamp in any way that they wish. - -1. Simulate an `applyFundingRate` transaction. An example of this be seen [here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/FundingRateMultiplierPriceFeed.js#L86). -2. Call `fundingRate` on the ETHBTC-PERP. - -The results will be in this format: - -``` -{ - rate, - identifier, - cumulativeMultiplier, - updateTime, - applicationTime, - proposalTime -} -``` - -Voters should use the `cumulativeMultipler` value. - -## Security Considerations -Adding this identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of funding rate proposers and disputers that can correctly manage the funding rate process. - -The self-referential nature of this identifier introduces additional security concerns. There is a possibility that ETHBTC-PERP price manipulation could be attempted to adjust the funding rate. - -Additionally, this is the first UMA identifier of its kind. With novelty comes extra risk, as it is possible that this implementation is flawed. If any issues are identified after approval, UMA voters can always edit this implementation or delist this price identifier. diff --git a/research/uma/umips/umip-63.md b/research/uma/umips/umip-63.md deleted file mode 100644 index ec8f7e47..00000000 --- a/research/uma/umips/umip-63.md +++ /dev/null @@ -1,69 +0,0 @@ -## Headers -| UMIP-63 | | -|------------|---| -| UMIP Title | Add INDEX & DPI as collateral | -| Authors | Gottlieb Freudenreich (gottlieb.freudenreich@gmail.com) -| Status | Approved | -| Created | 2020-03-08 | -| Discourse Link | https://discourse.umaproject.org/t/add-index-and-dpi-as-collateral/326 - -# Summary - -This UMIP will add INDEX and DPI to the supported collateral currencies on the global whitelist contract, allowing the usage of these 2 assets as collateral currencies. -More information on INDEX and DPI can be found on the website: https://www.indexcoop.com/ - -# Proposed Collateral Currencies - -## INDEX (Index Cooperative Token) -### Motivation - -INDEX is the governance token which presides over the Index Cooperative the curater of the DeFi Pulse Index. -The Index Cooperative has $130 million TVL and could utilize its governance token and/or treasury funds as collateral within the UMA ecosystem. - - -### Technical Specification -To accomplish this upgrade, two changes need to be made: - - * The INDEX address, [0x0954906da0bf32d5479e25f46056d22f08464cab][index], needs to be added to the collateral currency whitelist introduced in UMIP-8. - * A final fee of 24 INDEX needs to be added for the INDEX in the Store contract.

There is the theoretical risk that the underlying smart contracts get exploited which leads to a rapid loss of value in the currency proposed here which would require fast response to ensure solvency for any financial products built using this as a collateral type. \ No newline at end of file diff --git a/research/uma/umips/umip-64.md b/research/uma/umips/umip-64.md deleted file mode 100644 index ea6b2513..00000000 --- a/research/uma/umips/umip-64.md +++ /dev/null @@ -1,381 +0,0 @@ -## Headers -| UMIP-64 | | -|------------|---| -| UMIP Title | Add INDEX/ETH, ETH/INDEX, INDEX/USD, USD/INDEX, DPI/ETH, ETH/DPI, DPI/USD and USD/DPI as price identifiers | -| Authors | Gottlieb Freudenreich (gottlieb.freudenreich@gmail.com) -| Status | Approved | -| Created | 2020-03-08 | -| Discourse Link | https://discourse.umaproject.org/t/add-index-and-dpi-price-identifiers/327 - -# SUMMARY - -The DVM should support price requests for the following indexes - - - INDEX/ETH - - ETH/INDEX - - INDEX/USD - - USD/INDEX - - DPI/ETH - - ETH/DPI - - DPI/USD - - USD/DPI - - -# MOTIVATION - -The DVM currently does not support the INDEX/ETH, ETH/INDEX, INDEX/USD, USD/INDEX, DPI/ETH, ETH/DPI, DPI/USD and USD/DPI price indices. - -Supporting the DPI/USD and INDEX/USD price identifiers would enable the creation of a DPI/INDEX backed stablecoin, built using one of the perpetual stablecoin frameworks being developed on UMA.

- - -# RATIONALE - -Prices are primarily used by Priceless contracts to calculate a synthetic token’s redemptive value in case of liquidation or expiration. Contract counterparties also use the price index to ensure that sponsors are adequately collateralized. More complex computations (like incorporating additional exchanges, calculating a TWAP or VWAP, or imposing price bands, etc.) have the potential to add a greater level of precision and robustness to the definition of this identifier, particularly at settlement of each expiring synthetic token. - -The addition of INDEX/ETH, ETH/INDEX, DPI/USD, and USD/DPI fits into a larger goal of advancing the adoption of the UMA protocol by allowing INDEX and DPI to be used as collateral for minting derivatives within the UMA ecosystem, as well as other UMA based synthetics. This furthers adoption of the protocol by encouraging a convergence of capital from different projects and increasing TVL. - -Using the Uniswap Price should give the most accurate price for DPI/ETH and INDEX/ETH on the market as it has the deepest liquidity. Sushiswap liquidity is increasing but much lower. All AMM pools should be queried using a 1 minute TWAP to prevent flash-loan attacks and liquidations. - -The USD/ETH and ETH/USD Price can be calculated as per UMIP-6. - - -# IMPLEMENTATION - -**For INDEX/ETH and ETH/INDEX** - - 1.

In the current setting, there would need to be a significant event that erodes confidence in the Index Cooperative or the DPI token, causing Uniswap liquidity to be withdrawn quickly and en-masse. This threat is mitigated via INDEX incentives paid to liquidity providers who stake their tokens. The price on sushiswap should follow uniswap due to on chain arbitrage unless there is a serious problem with Ethereum. Furthermore, in also querying Binance this risk is minimized. - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. - - - - diff --git a/research/uma/umips/umip-65.md b/research/uma/umips/umip-65.md deleted file mode 100644 index e46716f5..00000000 --- a/research/uma/umips/umip-65.md +++ /dev/null @@ -1,305 +0,0 @@ - -## HEADERS -| UMIP-65 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add uTVL_KPI_UMA as a Price Identifier | -| Authors | Hart Lambur hart@umaproject.org, Mhairi McAlpine mhairi@umaproject.org | -| Status | Approved | -| Created | 4th March 2021 -| [Discourse Link](https://discourse.umaproject.org/t/add-utvl-kpi-uma-as-a-price-identifier/318) | - -# SUMMARY - -Key Performance Indicator(KPI) options are synthetic tokens that redeem to protocol tokens with the redemption value determined by performance against that indicator.

Within UMA, TVL plays the additional function of being the lower floor for the value of 0,5 $UMA, due to the design of UMA and the COC>POC inequality. - -1. What are the financial positions enabled by creating this synthetic that do not already exist? - - - The DVM does not currently support any form of KPI options. This synthetic token will allow the creation of tokens which expire to a set rate of the collateral asset tokens based on a pre-identified bounded ratio as determined by the TVL of the protocol at the time of expiry. - -2. Please provide an example of a person interacting with a contract that uses this price identifier. - - - A protocol may choose to leverage its community and/or its reputation by minting TVL Options for its token which can be redeemed to a token amount as determined by the TVL of the protocol at the expiry point. - - A protocol community member, tokenholder, voter or proximal Defi prtocol participant may be gifted a TVL option by a protocol as an incentive to build the TVL of the protocol within the option timeframe and redeem at expiry. - - Any user may purchase a TVL Option for a protocol that they believe has the potential for growth in TVL prior to expiry. - -3. The current TVL of UMA is approximately $83m as at 21.30(UTC) 5th March 2021. - -

While that assumption may be somewhat inaccurate, it has minimal impact on the overall calculation, cuts down on processing complexity, and works on a “common sense” attitude that wrapped bitcoin on the Eth chain are equivalent in value to native bitcoin. -There are other forms of wrapped BTC which are not approved as collateral within the UMA protocol. To maintain consistency it is suggested that this assumption is made for any other similar non-algorithmic wrapped Bitcoin. - -3. Four non-algorithmic dollar stablecoins (DAI, USDC, USDT, rDai]) are approved as collateral within the UMA Protocol. -It is assumed for this purpose that 1DAI=1USDC=1USDT=1rDAI=$1. While this assumption may be somewhat inaccurate, it has minimal impact on the overall calculation, cuts down on processing complexity and works on a “common sense” attitude that a dollar stablecoin is worth exactly $1. -There are other forms of dollar stablecoins which are not approved as collateral within the UMA protocol. To maintain consistency it is suggested that this assumption is made for any other non-algorithmic stablecoin. - -4. Five Liquidity Tokens (wBTC-Eth, USDC-Eth, UNI-Eth, UMA-Eth, bwBTC/ETH_SLP) are approved as collateral within the UMA protocol. -It is recommended that any additional proposal to add liquidity tokens as approved collateral currencies are evaluated against UMIP 59 and follow those market and data sources to calculate dollar value unless there is good reason for deviance. Note that the calculation of the dollar value of the liquidity token occurs in the penultimate step of the UMIP (Step 5). - -5.There are a variety of price identifiers for native ERC20 tokens. Calculation of the dollar value should follow the relevant UMIP where it exists, and where there is no Price Identifier UMIP, the three highest volume [ERC20]/USD* markets should be queried and the median value used. - - - There is no need for price processing. This is a snapshot based on a particular time, however it may be useful for TVL Options holders to have oversight of the ongoing TVL and consequently the value of their options on an ongoing basis.

- -# Security considerations - -1. Where could manipulation occur? - - - Negligible opportunities for manipulation. - -2. How could this price ID be exploited? - - - It is possible that as expiry approaches, a user may be able to purchase a large number of TVL option on the open market, should the TVL be significantly below the level required to achieve the ceiling level, then add large amounts of collateral to an UMA contract slightly before expiry to temporarily drive up the TVL, redeem the synthetic tokens, then withdraw the collateral immediately afterwards. - - - It is possible that a user may purchase uTVL_KPI_UMA at a low price, lock substantial amounts of collateral in UMA contracts causing the uTVL_KPI_UMA price to rise, then sell the these tokens at a profit and immediately withdraw the collateral from the contracts. - - - It is possible that as expiry approaches a user may purchase a large number uTVL_KPI_UMA at a low price near expiry on the open market should the TVL be significantly below the level required to achieve the ceiling of 2 $UMA per option, then deposit substantial amounts of collateral in UMA contracts with the intention of temporarily driving up the returns from the options, then immediately withdraw the collateral after expiry, causing an artificial spike in the TVL. Technical solutions were explored however it was considered that given the variety of potential manipulation and that whatever constraints put in place to mitigate this could be gamed, the DVM was a superior method of addressing any such attempts. In the event of such a manipulation attempt, and a dispute being raised, voters should come to consensus on what a true measure of the TVL locked in the protocol would have been by excluding the collateral used in the manipulation attempt. - - -3. Do the instructions for determining the price provide people with enough certainty? - - - YES - -4. What are current or future concern possibilities with the way the price identifier is defined? - - - It is likely that new forms of collateral will be approved prior to the expiry date. It is possible that they may not have a significant USD* market. Should a direct calculation not be possible the highest volume ETH market should be queried and conversion to a dollar value performed through UMIP6. - - It is possible that price identifiers for collateral types amy be altered prior to expiry - - It is possible that collateral types may be removed. This would not impact on this PI as they would not feature in any relevant contract. - - -5. Are there any concerns around if the price identifier implementation is deterministic? - - - This price identifier excludes collateral locked in Jarvis contracts and the optimistic oracle contracts. - - diff --git a/research/uma/umips/umip-66.md b/research/uma/umips/umip-66.md deleted file mode 100644 index 46f99512..00000000 --- a/research/uma/umips/umip-66.md +++ /dev/null @@ -1,35 +0,0 @@ -## Headers -| UMIP-66 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add USDBTC_18DEC, BCHNBTC_18DEC, ELASTIC_STABLESPREAD/USDC_18DEC, STABLESPREAD/USDC_18DEC, STABLESPREAD/BTC_18DEC and AMPLUSD_18DEC as supported price identifiers | -| Authors | Sean Brown (@smb2796) | -| Status | Approved | -| Created | March 10, 2021 | -| [Discourse Link](https://discourse.umaproject.org/t/propose-v2-pids-for-all-depreciated-pis/336) | | - - -## Summary (2-5 sentences) - -This UMIP proposes adding USDBTC_18DEC, BCHNBTC_18DEC, ELASTIC_STABLESPREAD/USDC_18DEC, STABLESPREAD/USDC_18DEC, STABLESPREAD/BTC_18DEC, AMPLUSD_18DEC as supported price identifiers. - -## Motivation - -With the introduction of the new EMP template proposed in UMIP-52, all price identifiers are required to be scaled by 10^18 when submitted on-chain. This is in contrast to the function in old EMP contracts, where the price identifier needed to be scaled to match the scaling factor of the collateral currency that the identifier was being used with. This means that price identifiers that are being used in an old EMP contract that has a non-18 decimal collateral currency cannot be used with the new contracts. - -Because of this, many price identifiers have been deprecated. This UMIP simply reproposes those price identifiers with slightly altered price identifier names and a scaling specification of 18 decimals. Everything else about these identifiers remains the same. The intention is that these price identifiers only be used while the original price identifiers are still deprecated. If the original price identifiers are at any point able to be used again, those should once again become the canonical price ids. - -## Technical Specifications - -Voters should refer to the rationale, technical specifications, implementations and security considerations in each corresponding UMIP. The only change to the implemenentations of these price identifiers are that these should all be scaled 10^18. Voters currently do not have to adjust results for any sort of scaling when voting through the UMA voter dapp, so the result that a voter would input for one of these price ids would be exactly the same as for the deprecated identifiers. - -The price identifier pairings are as follows. - -| New Identifier | Old Identifier | UMIP | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| --------------| -| USDBTC_18DEC | USDBTC | [UMIP-7](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-7.md) | -| BCHNBTC_18DEC | BCHNBTC | [UMIP-23](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-23.md) | -| ELASTIC_STABLESPREAD/USDC_18DEC | ELASTIC_STABLESPREAD/USDC | [UMIP-30](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-30.md) | -| STABLESPREAD/USDC_18DEC | STABLESPREAD/USDC | [UMIP-31](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-31.md) | -| STABLESPREAD/BTC_18DEC | STABLESPREAD/BTC | [UMIP-31](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-31.md) | -| AMPLUSD_18DEC | AMPLUSD | [UMIP-33](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-33.md) | - diff --git a/research/uma/umips/umip-67.md b/research/uma/umips/umip-67.md deleted file mode 100644 index edf60adb..00000000 --- a/research/uma/umips/umip-67.md +++ /dev/null @@ -1,44 +0,0 @@ -## Headers -| UMIP-67 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add SUSHI and xSUSHI as approved collateral currencies | -| Authors | Sean Brown (@smb2796) | -| Status | Approved | -| Created | March 10, 2021 | -| [Discourse Link](https://discourse.umaproject.org/t/add-sushi-and-xsushi-as-collateral-types/335) | | - -## Summary (2-5 sentences) -This UMIP will add Sushi and xSushi as approved collateral currencies.

The proposed final fee is 25 SUSHI and 22 xSUSHI per request. - -## Motivation - -SUSHI and xSUSHI are both ERC-20 tokens used by the SushiSwap community. SUSHI is the governance token of SushiSwap and is also used for staking. When SUSHI holders stake SUSHI, they receive xSUSHI in return. Each xSUSHI is thus exchangeable for a certain amount of staked SUSHI tokens. - -Adding SUSHI and xSUSHI as collateral types will allow for a variety of contract deployments. These could be used with the SUSHI/xSUSHI price identifiers that are also being proposed, to create SUSHI/xSUSHI backed yield dollars, or SUSHI/xSUSHI covered calls. - -## Technical Specification -To accomplish this upgrade, two changes for each currency need to be made: - -### SUSHI -- The SUSHI address, [0x6B3595068778DD592e39A122f4f5a5cF09C90fE2](https://etherscan.io/address/0x6b3595068778dd592e39a122f4f5a5cf09c90fe2), needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 25 needs to be added for SUSHI in the Store contract. - -### xSUSHI -- The xSUSHI address, [0x8798249c2E607446EfB7Ad49eC89dD1865Ff4272](https://etherscan.io/address/0x8798249c2E607446EfB7Ad49eC89dD1865Ff4272), needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 22 needs to be added for xSUSHI in the Store contract. - -## Rationale - -The rationale behind this change is giving deployers more useful collateral currency options. - -25 was chosen as the final fee for SUSHI, because this is approximately ~$500 at current SUSHI prices whcih is approximately equivalent to other collateral currencies. A slightly lower xSUSHI final fee of 22 was chosen, because xSUSHI will always trade slightly higher than SUSHI and this results in the same approximate dollar value. - -## Implementation - -This change has no implementation other than the two aforementioned governor transactions that will be proposed. - -## Security considerations - -The only security implication is for contract deployers and users who are considering using EMP contracts with SUSHI or xSUSHI as collateral currencies. Contract deployers and users of SUSHI and xSUSHI should be aware that these are both volatile currencies and sponsors should take care to keep their positions over-collateralized when using these. - -Since xSUSHI primarily functions as a SUSHI LP token, it does not have many liquid markets available.

The `balanceOf` SUSHI should be divided by the `totalSupply` of XSUSHI to determine the number of SUSHI that each XSUSHI is worth. -4. The price of SUSHIUSD should then be gathered in the same manner as explained in the section above. -5. The result of step 3 and step 4 should be multiplied to get the price of XSUSHIUSD. Voters should then round this result to 6 decimal places. -6. USDXSUSHI follows the same pattern except adds the additional step of taking the inverse of the XSUSHIUSD result. - -## Security Considerations - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -There are some security considerations associated with adding a low float token like XSUSHI as collateral. These are explained further in the XSUSHI collateral UMIP. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness (eg via TWAPs) are necessary to prevent market manipulation. \ No newline at end of file diff --git a/research/uma/umips/umip-69.md b/research/uma/umips/umip-69.md deleted file mode 100644 index 3f0e2558..00000000 --- a/research/uma/umips/umip-69.md +++ /dev/null @@ -1,293 +0,0 @@ -## HEADERS -| UMIP-69 | | -|------------|------------| -| UMIP Title | Add BCHDOM, BNBDOM, BSVDOM, DOTDOM, ETHDOM, LINKDOM, LTCDOM, USDTDOM & XRPDOM as price identifiers | -| Authors | Domination Finance (Josh Bowden (), Michal Cymbalisty (), et. al.) -| Status | Approved | -| Created | March 16, 2021 | -| Link to Discourse | https://discourse.umaproject.org/t/add-bchdom-bnbdom-bsvdom-dotdom-ethdom-linkdom-ltcdom-usdtdom-xrpdom-as-price-identifiers/346 | -

- -# SUMMARY -The DVM should support price requests for the relative market capitalization indices of these top 9 cryptocurrencies (according to CoinGecko). These indices are commonly known as *"dominance"* indices. Compared to other typical UMIP price identifiers, these indices are *unit-less* since they are simply a percentage represented as a whole number. - -Each price identifier for a particular cryptocurrency's market share in general is calculated by taking, - * the total *circulating* supply of that cryptocurrency, - * multiplied by the current price of the token in USD, - * divided by the global market cap of all cryptocurrencies. - -The price identifiers are constructed using the following formulations below. - -> **REMARK**  The formulas shown below gives the reader a general concept of how one arrives at the prices of these indices. In general, there can be significant deviations and methodology as to how data providers actually calculate coin dominance. Calculating global cryptocurrency market cap involves curating 5000+ coins, in CoinGecko's case, as querying live USD prices and outstanding supply of each of those coins on the market -- as well as providing accessible API access. We give a more long form explanation in "Rationale". - -> **REMARK**  The actual price identifier values are whole numbers out of 100. For example, a value of 12.34% is represented as the value -> raw decimal value of `12.34`. Therefore, all price identifier values for dominance indices will always be within the range `0.00 <= x < 100.00`, for some dominance index value `x`. - -``` -BCHDOM → [Total BCH circulating supply] - * [Price of BCHUSD] - / [Total crypto market cap (USD)] - -BNBDOM → [Total BNB circulating supply] - * [Price of BNBUSD] - / [Total crypto market cap (USD)] - -BSVDOM → [Total BSV circulating supply] - * [Price of BSVUSD] - / [Total crypto market cap (USD)] - -DOTDOM → [Total DOT circulating supply] - * [Price of DOTUSD] - / [Total crypto market cap (USD)] - -ETHDOM → [Total ETH circulating supply] - * [Price of ETHUSD] - / [Total crypto market cap (USD)] - -LINKDOM → [Total LINK circulating supply] - * [Price of LINKUSD] - / [Total crypto market cap (USD)] - -LTCDOM → [Total LTC circulating supply] - * [Price of LTCUSD] - / [Total crypto market cap (USD)] - -USDTDOM → [Total USDT circulating supply] - * [Price of USDTUSD] - / [Total crypto market cap (USD)] - -XRPDOM → [Total XRP circulating supply] - * [Price of XRPUSD] - / [Total crypto market cap (USD)] -``` - -# MOTIVATION - -The DVM currently does not support the listed dominance indices. Synthetic tokens which track market dominance could be used as hedging tools in one’s portfolio. These synthetic tokens can also be used as tools to speculate on a cryptocurrency's market share relative to all other cryptocurrencies. - -1. What are the financial positions enabled by creating this synthetic that do not already exist? - - - These synthetic tokens will enable users to enter into financial positions based on a particular coins market dominance. Previously, our team created an instrument on UMA to be able take positions on the, - - (i) relative market cap of Bitcoin (BTCDOM), as well as, - - (ii) all alt-coins against Bitcoin (ALTDOM). - - These new price identifiers allow users to take positions to long or short the relative market cap of these top 9 crypocurrencies. - - More importantly, not all these underlying cryptocurrencies are available to be traded on Ethereum. - -2. Please provide an example of a person interacting with a contract that uses this price identifier. - - - A user wanting to short a particular cryptocurrency's market dominance can mint synthetics and then market sell them. - - A user wanting to long a particular cryptocurrency's market dominance can market buy a synthetic token. - -

- -# RATIONALE - -Prices are primarily used in UMA to calculate a synthetic token’s value in case of liquidation or expiration. Contract counterparties, such as those running liquidation bots, also use the price index to ensure that sponsors are adequately collateralized. - -While coin domination can be succinctly represented as a single percentage, the underlying mechanisms for calculating it are quite involved and can dramatically differ by multiple percentage points from one data source to another. Calculating dominance involves knowing the current supply of a cryptocurrency, the prevailing market price of CRYPTOCURRENCY/USD, and the total market capitalization of all tokens in USD. More importantly, calculating the total market capitalization of all tokens in USD is a challenge since different data sources may altogether not include particular alt-coins thereby affecting all coin market dominance percentages. - -At the moment, market dominance is commonly referenced through three major sources: TradingView, CoinMarketCap & CoinGecko. However, unlike trading pairs which exhibit strong redundancy without deviation largely due to arbitrage incentives, each data source can vary by multiple percentage points due to differing calculation methodologies. Namely, each site has different methodologies for which alt-coins to admit into the total market cap, and a given coin’s market price and total coin circulation amounts may differ, compounding over hundreds or even thousands of alt-coins. Additionally, on a technical note, live and historical data update frequency varies and historical data may be paywalled, making it significantly harder to successfully run liquidation and dispute bots with redundancy and without paying for API access. To make matters worse, had we proposed a scheme where multiple data sources were used, we’d have to decide on using either the median or mean of the data sources and then have to specify some logic to handle if one of the data sources went down or starting to significantly different from the rest, for example. - -In an effort to alleviate these challenges, the Domination Finance team was able to get in touch with Bobby & TM, the co-founders of CoinGecko. The CoinGecko team went above and beyond to meet the requisites, updating CoinGecko’s coin dominance live data to 1-3 minute intervals from what was previously 10 minutes. Although this may introduce a single point of failure, we felt that the costs in increased complexity and mental load on the stakeholders who need to use it (like speculators, sponsors, liquidators & disputers) outweighed the benefits, especially during this period where the synthetic token is newly launched. - -While CoinGecko was able to provide the higher time granularity for coin dominance on short notice, historical data, necessary for dispute bots and voters, was unable to be immediately supplied from CoinGecko. Instead, constructing a separate caching service was necessary to track and record the historical data via polling CoinGecko's Live API to be able to compute historical coin dominance at a given point in time. Our caching API is more than sufficient to provide the historical data for dispute bots and voters. - -Initially, during normal operation, market dominance indices should closely track the value on CoinGecko. As more data sources for market dominance data are created and examined, voters are encouraged to add additional sources of information into the methodology for the price calculation. CoinGecko's full methodology for calculating dominance indices is detailed [here](https://www.coingecko.com/en/methodology). - -
- -# IMPLEMENTATION - -1. **What prices should be queried for and from which markets?** - - - The applicable price market dominance index should be queried depending on the cryptocurrency of interest. The current chosen method is to query for dominance indices from the Domination Finance API, which simply caches CoinGecko dominance data. - -2. **Pricing interval** - - - 1 min (round down relative to UTC) - -3. **Input processing** - - - None. - -4. **Result processing** - - - See rounding rules in *Technical Specification*. - - -For all price requests, voters should ensure that the calculated price does not differ greatly from broad market consensus. This is meant to be vague as the $UMA tokenholders are responsible for defining broad market consensus. This is especially important when relying on a third-party caching API; one possible way to verify this would be to query from the less granular CoinGecko API and compare results against those returned by Domination Finance API. - -
- -# Security considerations - -The current implementation relies on CoinGecko's and the Domination Finance's API endpoints to be able to receive accurate pricing information. Since calculating market dominance is an involved process with a number of variables at play, the trade-off is made to have a stable formulation from a single source instead of multiple sources which have widely varying calculation methodologies and public data availability. - -In the unlikely event that market index values returned from data sources are extreme outliers or erroneous compared to current market consensus, $UMA-holders may choose to use prevailing market consensus or using a nearby timestamp value instead. - -Anyone deploying a new priceless token contract referencing these identifiers should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for these identifiers and also contemplate de-registering these identifiers if security holes are identified. As noted above, $UMA-holders should also consider re-defining this identifier as liquidity in the underlying asset changes, or if added robustness is necessary to prevent market manipulation. diff --git a/research/uma/umips/umip-7.md b/research/uma/umips/umip-7.md deleted file mode 100644 index 5f1624de..00000000 --- a/research/uma/umips/umip-7.md +++ /dev/null @@ -1,85 +0,0 @@ -# Disclaimer - -The USDBTC price identifier has been deprecated.

Repeated analysis showed these same exchanges have the highest reputable volume for BTCUSD. - -Binance and Coinbase are both USD pairs, and Bitstamp is an USDT pair. Including any Tether pair means the prices could change due to the price of Tether. However, we decided that these two factors sufficiently mitigate this risk: the purpose of the DVM is to give token holders leeway to evaluate events, such as this, and adjust the price response accordingly. This is adequately captured by the language "determining whether that median differs from broad market consensus." Second, the USDT price could only have the effect of pulling the median towards the higher or lower of the 2 USD pairs, or it could fall right in between them. For this reason we believe the USDT concern is sufficiently handled - -We also considered an alternative set of exchanges.

The XIO/ETH pool’s liquidity ranking on Uniswap is currently #112. - -There are two primary roles for the XIO token within the Blockzero Labs ecosystem. First, the token acts as a governance token which allows community members (Citizens) to vote on important topics and decisions. Second, the XIO token acts as a redemption mechanism for future Blockzero assets. Holding XIO gives users the ability to access and claim alternative tokens. In the future, the XIO token will also be the primary governance token for the Blockzero Index (Treasury). - -Our team comprises over 22 core members, and we boast a wider community of over 8,000 dedicated community members we call “Citizens.” We take pride in being one of the most open and transparent communities in crypto, as evidenced by our regular Youtube livestreams, AMAs and open discussions, and high-quality engagement across our Social Forum and Telegram channels. - -We are dedicated to consistent innovation and ideation within the DeFi space, and future projects may encompass the likes of: a deflationary DEX, DeFi insurance, tokenized yield swaps, and the creation of a Blockzero Index (Treasury).

When ethVIX moves up, iethVIX moves down by an equivalent percentage, and vice versa. - -# Motivation - -ethVIX and iethVIX allow for the trading of model-free expected volatility of ETH. ethVIX is best understood as a long volatility position while iethVIX is a short volatility position. The ethVIX index is very similar to the Cboe VIX which tracks the expected volatility of the S&P 500. By trading ethVIX or iethVIX traders can take long or short positions against volatility, either as a speculative trade itself or a hedge for other speculative trades. - -Here are some examples of how traders might use ethVIX and iethVIX: -- In early March of 2020, 0xAlice believes that the global pandemic will greatly affect the price of ETH but she’s not sure if it will drop like the stock market or go up as a safe haven asset. She buys ethVIX for roughly 80 USDC per token. On Black Thursday (March 12th, 2020), the price of ETH drops significantly and the price of ethVIX moves to around 280 USDC. At expiration, 0xAlice redeems her ethVIX tokens while the price feed is still over 200 USDC. - -- In March of 2021, the price of ETH goes up quickly in a bull market. This volatility causes ethVIX to rise to roughly 120 USDC. iethVIX drops inversely to 80 USDC. 0xCarol believes that the price of ETH will soon stabilize.

Unlike other measures of volatility, the ethVIX (and VIX) use a model-free market based approach. Using a model-free approach gives the best calculation of expected future volatility. -Currently ethVIX is calculated by using out-of-the-money (OTM) call and put options from Deribit. This choice was made because Deribit’s market currently consists of roughly 80-90% of all ETH options volume. - -Manipulating the bids/asks on Deribit is the main vector of attack for changing the ethVIX price. Two things help to mitigate this attack. First, placing bids/asks that are not aligned with the market can be costly to an attacker if they are filled. Second, in certain cases when bids/asks become extremely skewed from their expected market prices, the price feeds use Deribit’s mark price instead of the bid/ask. -You can learn more about the approach used to calculate ethVIX in the [methodology paper](https://dvix.io/ethVIX_methodology.pdf). - -The settlement price calculation and the standard price request calculation are the same for both the ethVIX and iethVIX.

These can be found at https://dvix.io/api/latest?asset=ETH or for non-technical users at https://dvix.io/rawData. The settlement price is always the price of the feeds at 06:00 UTC on the day of contract expiry. Contracts will also expire at 06:00 UTC. - -In cases where users feel that the dVIX price feeds cannot be trusted, the following steps should be taken to calculate the ethVIX & iethVIX price feeds. - -## Step 1 - Use historical price feed. - -- Users can get 7 days of historical price feeds at https://dvix.io/api/historicalData?asset=ETH.

If they are also the final strikes for your calculation then no change needs to be made. - - - If they are not the final strikes then you need to calculate the final strikes with the following formula: `(FinalStrike - PreviousStrike) / 2`. `E42` and `E104` use this formula and you can copy and paste it to your final delta strikes. - - - Other Delta strikes need to be calculated with the following formula: `(NextStrike - PreviousStrike) / 2`. Cells `E20`-`E41` & Cells `E84`-`E103` use this formula. Make sure that all cells besides your first and last Delta strike use this formula. - - Fill the Grey highlighted cells with the following information: - - - `E148` - The first strike price less than or equal to cell `D148` in the series `B19`-`B75`. For example, in the sample data `1280` (`B25`) is the first strike below `1329.82` (`D148`). - - `E152` - The first strike price less than or equal to cell `D152` in the series `B83`-`B139`. For example, in the sample data `1280` (`B87`) is the first strike below `1332.04` (`D152`). - -# Security considerations - -Adding these new price identifiers pose certain risks: - -- Currently the options chain data used is from a centralized source (i.e. Deribit). -- Manipulation can occur on Deribit’s ETH options markets. As outlined previously this is mitigated in two ways: - - It will be expensive if the attacker’s orders are filled. - - In cases where prices are greatly misaligned with expected market prices the price feeds use the mark price instead of the bid/ask. -- To keep a 14-day average of volatility, the calculation rolls from one options expiry to another. This can lead to price swings but may also be a vector of attack. - - To mitigate this, we are launching weekly-expiring contracts after the next term rollover and having them expire before it occurs again. diff --git a/research/uma/umips/umip-75.md b/research/uma/umips/umip-75.md deleted file mode 100644 index f2dd5be7..00000000 --- a/research/uma/umips/umip-75.md +++ /dev/null @@ -1,53 +0,0 @@ -# Headers - -| UMIP-75 | | -| ---------- | ----------------------------------- | -| UMIP Title | Add bDigg as a collateral currency | -| Authors | Sean Brown (@smb2796) | -| Status | Approved | -| Created | April 7, 2021 | -| [Discourse](https://discourse.umaproject.org/t/add-bdigg-as-a-collateral-currency/854) | - -## Summary - -This UMIP will add bDigg, the BadgerDAO DIGG vault LP token, as an approved collateral currency. - -This will involve adding it to the whitelist and adding a flat final fee to charge per-request.

To avoid unnecessary redundancy, this UMIP will mostly reference that which has already been defined. - -# MARKETS & DATA SOURCES - -- The markets and data sources for bBadger/USD and [bwBTC/ETH SLP]/USD remain the same as the ones listed in [UMIP-39](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-39.md) for USD/bBadger and USD-[bwBTC/ETH SLP] respectively. -- To determine the underlying amount of DIGG for one bDIGG, the `pricePerFullShare` method needs to be queried on the bDIGG [contract](https://etherscan.io/address/0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a). This information is on-chain and can be queried with any method that a voter wishes to use, since there should not be variation in the returned values. -- The DIGG/USD price is determined based off of the markets and data sources listed for DIGGUSD in [UMIP-61](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-61.md). - -# PRICE FEED IMPLEMENTATION - -The price feeds for bBadger/USD and [bwBTC/ETH SLP]/USD will be exactly the same as the ones defined for USD/bBadger and USD-[bwBTC/ETH SLP]. The one change will be to not invert the price in the last step of the expression price feeds. These are the [USD/bBadger](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/DefaultPriceFeedConfigs.js#L530) and [USD-[bwBTC/ETH SLP]](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/DefaultPriceFeedConfigs.js#L561) price feed configurations. - -The bBadger/USD and USD/bBadger price feeds will be defined in a similar manner.

Rounding** - Round to 18 decimal places - - -# RATIONALE - -Pricing rationale is detailed in UMIP-39 and UMIP-61. - -# IMPLEMENTATION - -B wrapped tokens have 2 components to finding the underlying value of the tokens associated with them. Each wrapped token has a pricePerFullShare, which is the amount of underlying tokens that 1 b token could be redeemed for through the withdraw function. This underlying token can have different ways to determine its value depending on what type of token it is. - -The price per full share can be found by querying the contract of the token with `getPricePerFullShare` as seen in method 9 on this [contract](https://etherscan.io/address/0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a#readProxyContract). - -getPricePerFullShare is a pure view logic function in which no one has any authority to manipulate: - -``` -if (totalSupply() == 0) -{ - return 1e18; -} -return balance().mul(1e18).div(totalSupply()); -``` - -This returns the value of the balance of the vault divided by the number of shares to give the user the value of 1 share of the vault token. balance() represents the total balance of the underlying token in the vault. For example, if a user has 1 bDigg, this could be worth 1.2 Digg (which would be the ratio of balance / totalSupply). - -For bDigg you could use the same getPricePerFullShare method (described above) from the contract to get the underlying amount, and then the underlying values can be queried to give the price of one bDigg token in USD. - -## bBadger/USD - -The bBadger/USD pricing implementation will follow the same method that is laid out in [UMIP-39](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-39.md#usdbbadger-1) for USD/bBadger. The one difference will be to not take the inverse of USD/bBadger in step 8 and instead the result of step 7 should be rounded to 18 decimals to get the price of bBadger/USD. - -## [bwBTC/ETH SLP]/USD - -The bBadger/USD pricing implementation will follow the same method that is laid out in [UMIP-39](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-39.md#usd-bwbtceth-slp-1) for USD-[bwBTC/ETH SLP]. The one difference will be to not take the inverse of step 8 [bwBTC/ETH SLP]/USD in step 10 and instead round the result of step 9 to 18 decimals to get the [bwBTC/ETH SLP]/USD price. - -## bDiggUSD & USDbDigg - -To get the price of bDiggUSD perform the following steps. - -1. Query the getPricePerFullShare method on contract [0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a](https://etherscan.io/address/0x7e7e112a68d8d2e221e11047a72ffc1065c38e1a). This information is on-chain and can be queried in any way that a voter wishes at the price request block. -2. Gather the price of DIGGUSD by following the directions detailed in [UMIP-61](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-61.md). -3. Multiply bDigg/Digg by Digg/USD and round to 18 decimals to get the bDiggUSD price. -4. Take the inverse of the unrounded bDiggUSD result (1/(bDiggUSD)) to get the price of USDbDigg. This price should then be rounded to 18 decimals. - -# Security considerations - -Adding this new identifier by itself poses little security risk to the DVM or priceless financial contract users. However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to the reference asset’s volatility and liquidity characteristics to avoid the loss of funds for synthetic token holders. - -Although these are "wrapped" tokens, an objective value of the underlying collateral can be accurately determined to adequately inform both participating liquidators and disputers. - -The value of collateral can be objective in terms of price per full share * underlying asset value. - -If the vault was hacked in a way that drained funds, the price per full share would decrease in a way that makes the collateral "proportionally recoverable" for all users. There is also insurance from Nexus mutual to consider in terms of valuing the asset in the event of a covered vulnerability - -For context, the wrapping mechanism mints a token that represents a % share of a liquidity pool or vault. This is common practice when providing liquidity to an AMM or depositing into a yield optimizer. Using identifiers like price per full share, an oracle can deterministically calculate the value of what the unwrapped ERC20 tokens would be worth at any given time. - -Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. $UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier if security holes are identified. \ No newline at end of file diff --git a/research/uma/umips/umip-77.md b/research/uma/umips/umip-77.md deleted file mode 100644 index 9c5171f9..00000000 --- a/research/uma/umips/umip-77.md +++ /dev/null @@ -1,159 +0,0 @@ -## Headers -| UMIP-77 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add yUSD, RAI, COMP, YFI, ALCX, ALPHA, MKR, CRV, REN, RGT, and NFTX as approved collateral currencies | -| Authors | Deepanshu Hooda (deepanshuhooda2000@gmail.com), John Shutt (john@umaproject.org) | -| Status | Approved | -| Created | April 7, 2021 | -| [Discourse Link](https://discourse.umaproject.org/t/add-usdt-yusd-ust-susd-comp-yfi-alcx-rune-alpha-mkr-crv-ren-rgt-nftx-and-ruler-as-approved-collateral-currencies/712/2) | | - -# Summary (2-5 sentences) -This UMIP will add yUSD, COMP, YFI, ALCX, ALPHA, MKR, CRV, REN, RGT, and NFTX as approved collateral currencies.

The specifications for each price identifier are based on how we can find the most accurate price for the base currency. So, if a token has deep liquidity and high volume on Uniswap but little or no CEX activity, we would use a Uniswap TWAP.

The type of price that the DVM will return is dependent on the timestamp the price request is made at. This timestamp is the expiry timestamp of the contract that is intended to use this price identifier, so the TWAP calculation is used pre-expiry and the closing index value of uSTONKS calculation is used at expiry. This is very similar to the uGAS token and this design is outlined in [UMIP 22](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-22.md). - -Because the uSTONKS index value is only used at expiry, it will not be possible for a token sponsor to become undercollateralized based upon its movement. This means that only the Uniswap TWAP will need to be queried in real-time with a price feed. - -[Here](https://github.com/UMAprotocol/protocol/blob/master/packages/financial-templates-lib/src/price-feed/UniswapPriceFeed.js) is a reference implementation for an off-chain price feed that calculates the TWAP of a token based on Uniswap price data. - -## TECHNICAL SPECIFICATIONS -- Price Identifier Name: uSTONKS_JUN21 -- Base Currency: uSTONKS_JUN21 -- Quote currency: None. This is an index, but will be used with USDC. -- Intended Collateral Currency: USDC -- Scaling Decimals: 18 (1e18) -- Rounding: Round to nearest 6 decimal places (seventh decimal place digit >= 5 rounds up and < 5 rounds down) - -## RATIONALE -The uSTONKS token is an expiring token that settles at the end of the expiry month using the final exchange closing prices on the last business day of the month for the ten stocks in the basket. - -This price identifier will conditionally use a different price calculation methodology depending on the implied expiry state of the contract making the price request. This choice was made because uSTONKS is a decentralized synthetic that trades continuously 24/7 whereas the underlying stocks in the uSTONKS index trade during exchange hours which leaves gaps in prices between 4:00PM EST close and 9:30AM EST open the next day and on weekends and market holidays. Using price feeds from the exchanges to monitor collateral ratios of token sponsors could be problematic outside of market hours especially if there is significant news released or general macro market forces. Though some stocks are traded after hours, the ability to extract this price data is difficult and the frequency may not be consistent across all ten stocks. Therefore, using the uSTONKS token price itself to monitor collateral ratios is a much better alternative as it should reflect the actual price movements during exchange hours and also reflect expectations of price movements after market hours. - -A 2-hour TWAP was chosen to mitigate any risk of attempted price manipulation attempts on the market price of the synthetic. To meaningfully manipulate the price that token sponsors’ collateralization is calculated with, an attacker would have to manipulate the trading price of a token for an extended amount of time. This is described further in the Security Considerations section. - -The stocks chosen represent the stocks with the highest average comment volume on r/WallStreetBets. This index was picked on April 14th, 2021 using r/WallStreetBets comment analysis from swaggystocks.com, and will remain static throughout the life of the price identifier. - -## IMPLEMENTATION -Voters should determine which pricing implementation to use depending on when the price request was submitted. - -**At Expiry** - -If the price request's UTC timestamp is at 1625097600 (July 1, 2021 00:00:00 UTC), a price request for uSTONKS for a given timestamp should be determined by performing the `At Expiry` process. - -To create a baseline for the uSTONKS index, a base price for each stock was chosen. These prices are the closing prices of each on 04/14/2021 and can be used by voters as reference values for their calculations. Voters are highly encouraged to verify these values themselves. This basket is static - it will not change over the life of the contract. - -| Ticker | Stock Price 04/14/2021 | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| TSLA | 732.23 | -| PLTR | 23.70 | -| GME | 166.53 | -| AAPL | 132.03 | -| COIN | 328.28 | -| RIOT | 50.16 | -| SQ | 258.40 | -| MVIS | 12.34 | -| RBLX | 75.35 | -| MARA | 42.97 | - -Each stock also is assigned an index value base. The index is equally weighted, so each stock is assigned a base of 10. This means that on 04/14/2021 at close, the uSTONKS index would have been worth 100 with every component making up 1/10th of that index. - -To calculate the uSTONKS price, an UMA voter should: -1. Query for the close price of one component on June 30, 2021. It is recommended that voters use the Google Sheets GOOGLEFINANCE function. -2. Divide the June 30 price by the base price and multiply by the index value base (10) to get today’s index value. -3. Perform this function for each component in the index and sum all of the results together. -4. Round the result of step three to six decimal places - -An example of this calculation is shown in [this](https://docs.google.com/spreadsheets/d/1kccQQJ8FqSnaDbeK4ljXERIg9lKkErHXtvGSbPcDTAw/edit?usp=sharing) Google Sheet. - -It is possible that, over the life of this price identifier, certain situations could arise that would affect the validity of the index calculation. Guidance is provided below for certain situations, but voters are free to come to an alternative consensus if a flaw in the methodology is identified or an unforeseen event occurs. - -1. In the case of a stock split, the base price of the stock should be divided by the number of shares that the stock is being split into. As an example - if TSLA issued a 4:1 stock split, the base price of TSLA, 732.23, would be divided by 4 and the new base index price would be 183.06. -2. In the case of a stock consolidation, the process is the same as for a stock split, except the base price should be multiplied by the number of shares being consolidated. - -**Before Expiry** - -If the price request's UTC timestamp is less than 1625097600 (July 1, 2021 00:00:00 UTC), voters will need to calculate a 2-hour TWAP for the uSTONKS_JUN21 token’s price in USDC. The following process should be used to calculate the TWAP. -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (2 hours in this case). -3. A single Uniswap price is defined for each timestamp as the price that the uSTONKS_JUN21 / USDC pool returns in the latest block where the block timestamp is <= the price request timestamp. This is the price of 1 uSTONKS_JUN21 token in USDC. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will get an equal weight. -5. This results should be rounded to 6 decimals. - -For both implementations, voters should determine whether the returned price differs from broad market consensus. This is meant to provide flexibility in any unforeseen circumstances as voters are responsible for defining broad market consensus. - -## Security Considerations -Security considerations are focused on the use of the token price for monitoring collateral ratios. -- Token price manipulation - Under illiquid market conditions, an attacker could attempt to drive prices down to withdraw more collateral than normally allowed or drive prices up to trigger liquidations. However, it is important to note that almost all attacks that have been performed on DeFi projects are executed with flash loans, which allows the attacker to obtain leverage and instantaneously manipulate a price and extract collateral. Additionally, flash loans will have no effect on a tradable token price because the TWAP calculation is measured based on the price at the end of each block. Collateralization based off of a TWAP should make these attacks ineffective and would require attackers to use significantly more capital and take more risk to exploit any vulnerabilities. -- Mismatch between TWAP and gap higher in token price - An aggressive gap higher in the token price accompanied by real buying and then a follow through rally could create a concern. In this scenario we could see the TWAP of the token significantly lag the actual market price and create an opportunity for sponsors to mint tokens with less collateral than what they can sell them from in the market. It is important to note that this is an edge case scenario either driven by an irrational change in market expectations or it can be driven by a “fat finger” mistake which is a vulnerability to any market. Even in this edge case we believe the design of the token and the parameters chosen should mitigate risks. The current Expiring Multi Party (EMP) contract requires sponsors to mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200% for other contracts. Therefore, assuming the GCR is similar for uSTONKS_APR21, the market would need to first rally at least 100% before potentially being exposed. If the sponsor wishes to withdraw collateral below the GCR they would request a “slow withdrawal” which would subject him to a 2 hour “liveness period” where anybody can liquidate the position if it fell below the required collateral ratio. The combination of the GCR and 2 hour “liveness period” allows the 2 hour TWAP to “catch up” to the market price and would protect from this scenario and deter sponsors from attempting to exploit it. - -Security considerations, like the ones above, have been contemplated and addressed, but there is potential for security holes to emerge due to the novelty of this price identifier. - -Additionally, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Contract deployers should also ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -$UMA-holders should evaluate the ongoing cost and benefit of supporting price requests for this identifier and also contemplate de-registering this identifier or editing its implementation if security holes are identified. diff --git a/research/uma/umips/umip-8.md b/research/uma/umips/umip-8.md deleted file mode 100644 index 86ef5b4a..00000000 --- a/research/uma/umips/umip-8.md +++ /dev/null @@ -1,36 +0,0 @@ -## Headers -| UMIP-8 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add Global Collateral Currency Whitelist | -| Authors | Matt Rice (matt@umaproject.org), Clayton Roche (clayton@umaproject.org) | -| Status | Approved | -| Created | July 16, 2020 | - -## Summary (2-5 sentences) -This UMIP will have the effect of introducing a new global whitelist contract that will allow new collateral currencies to be added without deploying any new contracts.

This originality has lead to them being highly valued and having consistent enough trade volume. -* _30 day median_: The 30 day median allows for the index to reflect common trading prices across many CryptoPunks rather than to respond to particular transactions -* _Unique CryptoPunks_: We only use the most recent trade price for each CryptoPunk. This is a security feature since if we used each transaction then a single person could trade one CryptoPunk amongst accounts they owned to manipulate the price. -* _Median rather than the mean_: Calculating the mean incorporates the price of every single transaction which means that someone who owned a single CryptoPunk could have a small effect on the price. The median can still be manipulated but, given the uniqueness restriction above, it would require someone to own enough CryptoPunks to make up half of the monthly transactions. - -The `PUNKETH_TWAP` price is necessary to support a market in which people may disagree about the fundamental value of the asset going forward. At expiry, there is a clear way to value the `uPUNK`, i.e., the `PUNKETH` price, however, the value of uPUNK prior to that seems less obvious and we'd like to let the markets price the asset. - -This self-referential component was also used in uGAS, see [UMIP 22](./umip-22.md) and has proven successful in that context. - - -# Implementation - -### PUNKETH - -When a price request is made, the following process should be followed: - -1. Retrieve all CryptoPunk `PunkBought` events from the 30 days prior to expiration -2. Identify the last price that each CryptoPunk was traded at using the event data -- Only one price should be produced per CryptoPunk even if they had traded multiple times. Due to a [bug in the CryptoPunk Market](https://github.com/UMAprotocol/UMIPs/pull/261#discussion_r622282931), this isn't as straightforward as reading the most recent value from the `PunkBought` event. The process we use is: - - Scan through all of the `PunkBought` events and identify the function call that generated the `PunkBought` event: - - If it was generated by `buyPunk` then use the `PunkBought.value` price - - If it was generated by `acceptBidForPunk` then we load all of the `PunkBidEntered` for that particular CryptoPunk and use the most recent bid (only one bid can be outstanding at a time and is always the highest) -3. Take the median of these prices - If there is an even number of prices, take the mean of the two values closest to the median. -4. Divide by 1000, and then round to 6 decimals to arrive at the final price. - - -**Example** - -If the timestamp requested was `1619222400` then: - -* We would need to identify all `PunkBought` events from `1619222400 - 30 days -> 1616630400` to `1619222400` -* Imagine that we had 5 `PunkBought` events with (`ts`, `punk_id`, `eth`) pairs of `[(1616630450, 1000, 20), (1616631450, 5000, 30), (1616631550, 5000, 35), (1618631550, 6000, 22), (1618632550, 9999, 15)]`. -* We would need to check what function generated each `PunkBought` event. Suppose they were all generated by `buyPunk`, then the prices we would use to compute the median would be `[20, 35, 22, 15]` -* There are an even number of values, so there's no "median value" in the data -- Thus we find the number between the two values closest to the median `[20, 22]` to get a price of `21` -* Divide by `1000` to get a price of `0.021` - -### PUNKETH_TWAP - -When a price request that relies on this price identifier is made, the following process should be followed: - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp - TWAP period (2 hours). -3. A single Uniswap price is defined for each timestamp as the price that the ETH/uPUNK ppool returns at the end of the latest block whose timestamp is less than or equal to the timestamp that is queried for. -4. The TWAP is an average of the prices for each timestamp between the start and end timestamps. Each price in this average will receive equal weight. -5. The final price should be returned with ETH - - -**Example** - -If the timestamp requested was `1619222400` then: - -* The end TWAP timestamp would be `1619222400` -* The start TWAP timestamp would be `1619222400 - 7200` -> `1619215200` -* The Uniswap price would be found for \{`1619215200`, `1619215201`, `1619215202`, ..., `1619222400`\} -* Average the prices corresponding with each price and then report this average - - -# Security Considerations - -### PUNKETH - -One of the main concerns is that someone with sufficient CryptoPunks chooses to manipulate the price. - -For example, there are accounts that own about 400 unique CryptoPunks and the unique number of CryptoPunks that traded in the last 30 days is about 600. An individual who owns 400 CryptoPunks and traded them amongst their own accounts at prices near zero could corrupt the price by driving it to zero after having minted and sold the tokens at a high price. - -One benefit to using an oracle with human intervention is that voters could recognize this type of price manipulation and there are other viable proxies for the expected price of a CryptoPunk. For example, if voters felt like there was price manipulation, they could choose to settle the contract at the current market price of `PUNKBASIC` or other - -The other main concern is if there were just insufficient CryptoPunk trades being made. If there were only 1-2 trades happening every 30 days, this index becomes much less useful because there's less information contained in its price. - -### PUNKETH_TWAP - -The main concerns of the TWAP price are: - -1. **Token price manipulation**: If the Uniswap pool is not sufficiently liquid, then attackers could try to drive down the Uniswap price and withdraw more collateral than intended. Most DeFi attacks have been done using flash loans, but flash loans would be ineffective since the price is measured at the end of each block. Collateralizaton based on the TWAP price would make it more capital intensive (and thus risky) to target the token price in this way. -2. **TWAP mismatch**: If the price of the token rises quickly then there would become a mismatch between the market price and the TWAP price. This might allow sponsers to mint tokens with less collateral than what they could sell them for on the market. Reasonable levels of collateralizaton requirements and the 2 hour "liveness period" help combat this concern. - -Both of these concerns are originally discussed in [UMIP 22](./umip-22.md) diff --git a/research/uma/umips/umip-85.md b/research/uma/umips/umip-85.md deleted file mode 100644 index 9ac0b6ec..00000000 --- a/research/uma/umips/umip-85.md +++ /dev/null @@ -1,301 +0,0 @@ -## HEADERS - -| UMIP-85 | | -| ----------------- | ----------------------------------------------------------------------------------------------- | -| UMIP Title | Add R3_10H_TWAP and R3_30D_GM as supported price identifiers | -| Authors | Ashutosh Varma (ashutoshvarma11@live.com) | -| Status | Approved | -| Created | April 1, 2021 | -| Link to Discourse | [LINK](https://discourse.umaproject.org/t/add-rai-redemption-rate-apr-as-price-identifiers/624) | - -# SUMMARY - -This UMIP will reference a synthetic token to be created with this price identifier. -This token will be referred to as 'R3' (Rai Redemption Rate) and will represent the token that tracks these identifiers. - -The DVM should support price requests for the R3_10H_TWAP and R3_30D_GM price indices. - -The DVM should support requests for a price that resolves to either the 30 day geometric mean (R3_30D_GM) or -a 10-hour Time-Weighted Average Price (R3_10H_TWAP) of RAI redemption rate coefficient APR. - -The price resolution method to use will depend on the timestamp the price request was made at. - -For a price request made at or after the expiry timestamp, the price will be resolved with the R3_30D_GM, -30 day geometric mean of redemption rate coefficient APR calculation defined as per R3 token Technical Specification. - -For a price request made before the expiry timestamp, the price will be resolved to R3_10H_TWAP, a 10-hour TWAP of -redemption rate coefficient APR. - -# MOTIVATION - -The DVM currently does not support reporting 30 day geometric mean or 10-hr TWAP of RAI redemption rate coefficient APR. - -1.

- -# IMPLEMENTATION - -For querying the historical redemption rate coefficient APR, RAI subgraphs should be used, with sample query from -MARKET & DATA SOURCES - -```graphql -{ - redemptionRates( - first: 1000 - orderBy: createdAt - orderDirection: desc - where: { createdAt_gte: START_TIMESTAMP, createdAt_lte: END_TIMESTAMP } - ) { - annualizedRate - } -} -``` - -### R3_10H_TWAP (Pre-cutoff) - -For price requests made before the cutoff, use this 10-hour TWAP calculation implementation. - -RR = Redemption rate coefficient value -TT = Total time window (10hrs) -TI = Time interval for which RR value persisted - -1. The end TWAP timestamp equals the price request timestamp. -2. The start TWAP timestamp is defined by the end TWAP timestamp minus the TWAP period (10 hours in this case). -3. A single redemption rate coefficient APR value (RR) is defined for each timestamp as the price that the subgraph - returns at the end of the latest block whose timestamp is <= the timestamp that is queried for. -4. The TWAP is a time weighted average of the rates for each timestamp between the start and end timestamps. - Each price in this average will get weight equal to its time period (TI). TWAP will be calculated as ∑(RR * TI) / TT -5. As the values from subgraph are integers, so it should be left as returned without any scaling transformation. -6. The final price should be submitted with 18 decimals but rounded to 2 decimal places. For example, if the value is - 1.384827478767976545678765456, then round to 2 decimal places and convert 1-to-1 to RAI for 1.38 RAI. - -**For Example:-** -If price request timestamp is T1, then calculate end TWAP timestamp (T2) by simply subtracting 10-hours. -Run the query with START_TIMESTAMP=T1 and END_TIMESTAMP=T2 and apply the above calculation on retrieved data to -get the 10-hour TWAP of redemption rate coefficient APR. - -### Post-cutoff - -``` -GM = (product of values) ^ (1/number of values) -``` - -For price requests made after the cutoff, use this 30-day Geometric Mean calculation implementation. - -1. The end GM timestamp equals the price request timestamp. -2. The start GM timestamp is defined by the end GM timestamp minus the GM period (30 days in this case). -3. Only rates whose timestamp is greater than equal to start GM timestamp and less than equal to end GM timestamp - are used and rest should be discarded. -4. Calculate the product of all rates by simply multiplying them together. -5. Calculate the total number of rates. -6. The GM is the (value from step3) ^ 1/(value from step4). -7. The final price should be submitted with 18 decimals but rounded to 2 decimal places. For example, if the value is - 1.384827478767976545678765456, then round to 2 decimal places and convert 1-to-1 to RAI for 1.38 RAI. - -**For Example:-** -If price request timestamp is T1, then calculate end GM timestamp (T2) by simply subtracting 30-days. -Run the query with START_TIMESTAMP=T1 and END_TIMESTAMP=T2 and apply the above calculation on retrieved data to -get the 30-day GM of redemption rate coefficient APR. - -
- -# Security considerations - -Security considerations are focused on the use of the redemption rate for monitoring collateral ratios. - -- **Intentional Liquidation** - Since RAI dampen the ETH movement, any changes in ETH price are reflected shortly in RAI in form of - change in redemption rate. Therefore an attacker could use this to cause intentional liquidations. - Assume ETH price shoots up and R3 market price double in anticipation of increase in redemption rate. - Now the attacker can mint the synths at considerably lower price and sell them to market at higher price which - can result in intentional liquidations if his/her profit is higher than collateral locked. - However it is important ot note that the current Expiring Multi Party (EMP) the contract requires sponsors to - mint tokens with enough collateral to meet the Global Collateral Ratio (GCR) which has stood well above 200%. - Therefore assuming the GCR is similar for R3 and additionally setting the minimum CR to 200% or above should prevent intentional liquidations. We believe the design of the token and the parameters chosen should mitigate risks. The combination of the GCR and minimum CR allows the 10 hours TWAP to “catch up” to the market price and - would protect from this scenario and deter sponsors from attempting to exploit it. - -Security considerations, like the ones above, have been contemplated and addressed, -but there is potential for security holes to emerge. - -Additionally, anyone deploying a new priceless token contract referencing these identifier should take care to parameterize the contract -appropriately to avoid the loss of funds for synthetic token holders. -It is recommended to set higher minimum CR for priceless token contracts using this price feed. - -Contract deployers should also ensure that there is a network of -liquidators and disputers ready to perform the services necessary to keep the contract solvent. diff --git a/research/uma/umips/umip-86.md b/research/uma/umips/umip-86.md deleted file mode 100644 index 87fcc223..00000000 --- a/research/uma/umips/umip-86.md +++ /dev/null @@ -1,84 +0,0 @@ -# Headers - -| UMIP-86 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add LUSD as a supported collateral currency | -| Authors | Ramy Melo (Ramysmelo@gmail.com) | -| Status | Approved | -| Created | April 22, 2021 | -| Discourse Link | https://discourse.umaproject.org/t/add-lusd-collateral-support-to-dvm/929 | - -## Summary (2-5 sentences) - -This UMIP will add LUSD as approved collateral currencies.

(Robust as in legitimate liquidity, legitimate volume, price discrepancies between exchanges, and trading volume between exchanges)** - -Uniswap has the vast majority of FARM volume and depth. These should be used over all other sources. - -**What is the potential for the price to be manipulated on the chosen exchanges?** - -iFARM is not a collateral currently on any loan services and the majority of the liquidity is locked into profit share vaults. The potential risk for this is low. - -**Should the prices have any processing (e.g., TWAP)?** - -Processing is defined in the implementation section. - -# IMPLEMENTATION - -iFARM is an interest bearing receipt representing a compounding amount of FARM deposited into the Harvest profit sharing pool. Each wrapped token has a pricePerFullShare, which is the amount of underlying FARM tokens that 1 iFARM could be redeemed for through the withdraw function. This underlying token can have different ways to determine its value depending on what type of token it is. - -The price per full share can be found by querying the contract of the token with `getPricePerFullShare` as seen in method 9 on this [contract](https://etherscan.io/address/0x1571eD0bed4D987fe2b498DdBaE7DFA19519F651#readProxyContract). - -getPricePerFullShare is a pure view logic function in which no one has any authority to manipulate. The reference code cited above returns this value in in a data.csv file by block. - -This returns the value of the balance of the vault divided by the number of shares to give the user the value of 1 share of the vault token. balance() represents the total balance of the underlying token in the vault. For example, if a user has 1 iFARM, this could be worth 1.06 FARM (which would be the ratio of balance / totalSupply). - -For iFARM you could use the same getPricePerFullShare method (described above) from the contract to get the underlying amount of FARM, and then the underlying values can be queried to give the price of one FARM token in ETH. That in turn can be converted to USD by querying the ratio of ETH/USD using UMIP-6. - -For both implementions, a block number will need to be used. The block number should be the block that is closest to and before the timestamp that the price request timestamp. - -## Determining the iFARMUSD and USDiFARM prices - -**A.

To update the collateral currencies, one would need to deploy a new template. Expiries could only be at the beginning of the month, and all liveness periods had to be 2 hours. These parameter choices were made to keep the risks as low as possible as the first few EMPs were being deployed on mainnet. Now that there have been multiple successful deployments of the EMP contract, we propose that these parameters become more flexible to allow anyone to experiment with parameters of their choice. - -## Technical Specification -To accomplish this upgrade, a new financial contract template must be deployed: -- A modified `ExpiringMultiPartyCreator` contract will need to be deployed. The notable changes include: - - On each attempted deployment, this contract should query the `“CollateralWhitelist”` address using the `Finder` contract to find the whitelist address. Then it should verify that the provided collateral currency is on said whitelist. - - On each attempted deployment, this contract should allow any timestamp to be provided as the expiry. Note: the `ExpiringMultiParty` contract has a check that requires the timestamp to be in the future at deployment time. - - On each attempted deployment, this contract should allow the deployer to pass in the withdrawal and liquidation liveness, and it should check that they are both > 0. - - The EMP that is deployed by the creator will have minor changes in the events it produces detailed [here](https://github.com/UMAprotocol/protocol/pull/1753). - -After deployment, this new `ExpiringMutltiPartyCreator` contract should be approved as a ContractCreator in the Registry. - -Note: the voters only vote for the approval -- the deployment has no effect on the protocol until added as a ContractCreator. - -## Rationale - -Part of the rationale behind this change is that it’s simpler to deploy one `ExpiringMultiPartyCreator` contract that allows users to deploy almost any EMP parameterization than deploying an `ExpiringMultiPartyCreator` contract each time there’s a new use case. - -## Implementation - -Please see this [directory](https://github.com/UMAprotocol/protocol/tree/master/core/contracts/financial-templates/expiring-multiparty). The directory contains both the [implementation](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/expiring-multiparty/ExpiringMultiParty.sol) of the `ExpiringMultiParty` template and the [deployer contract](https://github.com/UMAprotocol/protocol/blob/master/core/contracts/financial-templates/expiring-multiparty/ExpiringMultiPartyCreator.sol) that will be registered with the DVM to allow users to deploy their own `ExpiringMultiParty` contract. Note: the changes specified above are currently in progress, so the current version may not match the specification yet. - -The new `ExpiringMultiPartyCreator` contract changes since the previously approved version were implemented [here](https://github.com/UMAprotocol/protocol/pull/1746). Additionally, the minor event changes that were made to the `ExpiringMultiParty` contract are implemented [here](https://github.com/UMAprotocol/protocol/pull/1753). These are the only changes that have been made since the previous version of the `ExpiringMultiPartyCreator` was deployed and approved. - -## Security considerations -These changes *have not* been audited. However, the changes are deemed to be minor and an audit is expected to come soon after its addition to the system. This is deemed to be safe because no *stateful logic* has been changed in the `ExpiringMultiParty` and the `ExpiringMultiPartyCreator` changes only affect the possible parameterizations of the `ExpiringMultiParty` contracts that can be deployed. - -As before, anyone deploying a new priceless token contract should take care to parameterize the contract appropriately to avoid the loss of funds for users. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. Anyone planning to use a synthetic token (as a sponsor or tokenholder) should validate that the token is solvent and well-parameterized before using since there are configurations and states that make the proposed contract unsafe. - -These considerations should be taken more seriously now that there are fewer limitations on what parameters a deployer can specify for an EMP contract. diff --git a/research/uma/umips/umip-90.md b/research/uma/umips/umip-90.md deleted file mode 100644 index 4687fe4b..00000000 --- a/research/uma/umips/umip-90.md +++ /dev/null @@ -1,153 +0,0 @@ -## Headers -| UMIP-90 | | -|------------|----------------------------------------------------------| -| UMIP Title | Add NGNUSD, PHPUSD, CADUSD, ZARUSD, KRWUSD and JPYUSD as price identifiers | -| Authors | Vsevolod Potorocha (vsevolod@jarvis.network) | -| Status | Approved | -| Created | 30/04/2021 | -| Discourse link | https://discourse.umaproject.org/t/umip-90-ngn-php-cad-zar-krw-and-jpy-vs-usd/1033 - -## Summary -The DVM should support price requests for the NGNUSD, PHPUSD, CADUSD, ZARUSD, KRWUSD and JPYUSD price index. - -## Motivation -The DVM currently does not support these Forex price index. - -### Cost: -While Forex data are free through open centralized exchange, brokers, and other sources APIs, the most reliable are paid.

Historical NGNUSD price from TraderMade are not accessible before April, 30th 2021 (not issue). Price requests should use the minute price that is nearest and later than the price request timestamp. To do this, voters should use the open price of the OHLC period that the price request timestamp falls in. TraderMade endpoints are queried based on the OHLC period's close time. - -As an example, a request for a CADUSD price at 2020-11-11-01:52:16 should use query for the period ending at 2020-11-11-01:53:00 and use the open price. - -The TraderMade endpoint used would be: https://marketdata.tradermade.com/api/v1/minute_historical?currency=CADUSD&date_time=2020-11-11-13:01&api_key=apikey - -NGNUSD, PHPUSD, CADUSD, ZARUSD, KRWUSD and JPYUSD should then be rounded to 5 decimals. - -TraderMade’s price feed is an aggregated feed from multiple Tier One and Two Banks, Market-Makers and Data Providers. They are popular with Quantitative Traders, Fintech companies and Institutional customers who require a high quality and trusted feed. - -### Weekend timestamp - -Over the weekend or some official holidays the REST API does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). - -Due to unavailability of price feed for foreign exchange rates and commodities over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - -Please note that this is different than the normal calculation process, which requires using the open price of the period that the price request falls in. - -### Forex markets working hours - -Forex markets are usually open throughout business days from 10:00 PM UTC time on Sunday, until 9:00 PM UTC time on Friday. However it is good to note that some brokers might close their price feeds 5-10 minutes prior to the official market closing time, thus the latest price given from the broker will be used as a official price for the asset. We should also note here that during those minutes the price remains flat without any changes, however theoretically it is possible to have a stronger price movement. - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation).

There might be some slight differences, however they are quite insignificant and would not affect the liquidation or dispute processes.

However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of JPYUSD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap on JPY/USD, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. \ No newline at end of file diff --git a/research/uma/umips/umip-91.md b/research/uma/umips/umip-91.md deleted file mode 100644 index 91158afc..00000000 --- a/research/uma/umips/umip-91.md +++ /dev/null @@ -1,1389 +0,0 @@ -## HEADERS -| UMIP-91 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add LONUSD, USDLON, BANKUSD, USDBANK, MASKUSD, USDMASK, VSPUSD, USDVSP, SFIUSD, USDSFI, DEXTFUSD, USDDEXTF, ORNUSD, USDORN, BONDUSD, USDBOND, PUNK-BASICUSD and USDPUNK-BASIC as price identifiers | -| Authors | John Shutt (john@umaproject.org), Deepanshu Hooda (deepanshuhooda2000@gmail.com) | -| Status | Approved | -| Created | April 29, 2021 -| Link to Discourse | [Link](https://discourse.umaproject.org/t/add-lonusd-usdlon-bankusd-usdbank-maskusd-usdmask-vspusd-usdvsp-sfiusd-usdsfi-fraxusd-usdfrax-dextffusd-usddextf-ornusd-usdorn-bondusd-usdbond-punk-basicusd-and-usdpunk-basic-as-price-identifiers/1036) - - -# SUMMARY - -The DVM should support price requests for the below price indices: -- LON/USD -- USD/LON -- BANK/USD -- USD/BANK -- MASK/USD -- USD/MASK -- VSP/USD -- USD/VSP -- SFI/USD -- USD/SFI -- DEXTF/USD -- USD/DEXTF -- ORN/USD -- USD/ORN -- BOND/USD -- USD/BOND -- PUNK-BASIC/USD -- USD/PUNK-BASIC - -The canonical identifiers should be `LONUSD`, `USDLON`, `BANKUSD`, `USDBANK`, `MASKUSD`, `USDMASK`, `VSPUSD`, `USDVSP`, `SFIUSD`, `USDSFI`, `DEXTFUSD`, `USDDEXTF`, `ORNUSD`, `USDORN`, `BONDUSD`, `USDBOND`, `PUNK-BASICUSD` and `USDPUNK-BASIC`. -# MOTIVATION - -1.

Please provide an example of a person interacting with a contract that uses these price identifiers. - -- Any of the base currencies could be used to mint yield dollars or other synthetics, and liquidators could identify undercollateralized positions by comparing the USD value of the synthetic to the value of the locked collateral. -- Base currency call options could be minted and paid out based on the USD price of the base currency at expiry. -- KPI options tied to the price of the base currency could be minted, with a payout increasing as the base currency price increases. - -# RATIONALE - -All of these base currencies have deep liquidity on Uniswap, SushiSwap, or both, and some have good liquidity on centralized exchanges, as well. The specifications for each price identifier are based on how we can find the most accurate price for the base currency. So, if a token has deep liquidity and high volume on Uniswap but little or no CEX activity, we would use a Uniswap TWAP.

- -# SUMMARY - -The DVM should support price requests for the [CRSP US Total Market TR Index](http://www.crsp.org/products/investment-products/crsp-us-total-market-index) (CRSPTMT), a highly diversified index that aims to track the US stock market as a whole. - -
- -# MOTIVATION - -UMA already counts with many price identifiers enabling the creation of derivatives on crypto assets and prices, as well as some identifiers for traditional, off-chain financial products like gold or stocks. However, access to highly diversified indices tracking large sectors of the economy are sorely lacking. Having exposure to broad indices could prove beneficial to people outside the US, as these products provide excellent risk-adjusted returns. In particular, they provide a relatively low risk strategy to beat USD inflation. - -The [Center for Research in Security Prices](http://www.crsp.org/products/documentation/crsp-indexes) (CRSP) is a data provider affiliated to the University of Chicago that maintains several such indices. Of all of them, the [US Total Market Total Return Index](http://www.crsp.org/products/investment-products/crsp-us-total-market-index) (CRSPTMT), is the most comprehensive and realistic metric of total US stock market performance, as it includes nearly all publicly traded US companies and it accounts for dividends. - -

- -# RATIONALE - -A self-referential price before expiry avoids price drift when US markets are not trading (nights and weekends). This requires token sponsors to set an initial price; it is recommended they consult the Google Finance price when doing this, as they may be arbitraged otherwise. - -Short-lived price manipulation of an AMM is relatively cheap, but it becomes expensive over time as the position can be easily arbitraged. This motivates the introduction of TWAPs, in line with [Uniswap's recommendation for building price oracles](https://uniswap.org/docs/v2/smart-contract-integration/building-an-oracle/). - -
- -# IMPLEMENTATION - -The contract will expire at 16:00 EST on 2021/09/21. The corresponding POSIX timestamp is `1632254400`. To determine the price, the DVM will choose between the two protocols described below depending on the timestamp of the oracle request, `request_timestamp`. - -- If `request_timestamp >= 1632254400`, use the "After expiry" protocol. -- Otherwise, use the "Before expiry" protocol. - -## After expiry - -After expiry, the contract should be settled according to the close price of the index on 2021/09/21. This price will be obtained by calling the `GOOGLEFINANCE` function on Google Sheets with the following parameters: - -``` -=GOOGLEFINANCE("CRSPTMT", "close", DATE(2021, 5, 21)) -``` - -This query can be done without API keys and at no cost to the user. Although querying the price via Google Sheets is preferred, it can also be accessed using web interface provided by [Google Search](https://www.google.com/search?hl=en&q=CRSPTMT). - -## Before expiry - -Before expiry, the price will be determined by the on-chain secondary market. At any time, the price will be the 2h Time-Weighted Average Price (TWAP) of the Uniswap uCRSPTMT_SEP21/USDC pool with the largest liquidity. - -Voters should follow this protocol to determine the price: - -1. Find the uCRSPTMT_SEP21/USDC Uniswap pool with the largest liquidity. -2. Determine the price of uCRSPTMT_SEP21 in USD returned by the pool for every timestamp between the request timestamp minus 2 hours and the request timestamp, inclusive. -3. The price to return is the arithmetic mean of all the prices at each timestamp, rounded to 6 decimals as explained below. - -# Security considerations - -1. Where could manipulation occur? -If trading is not very liquid, the price could be temporarily manipulated before expiry by executing large trades on Uniswap. However, we note that sustaining the attack for the whole duration of a 2h TWAP would be too costly and probably not worth it. - -2. What are current or future concern possibilities with the way the price identifier is defined? -After expiry, the price ID relies on a single data source. If Google Finance was down at the time for whatever reason, this could delay contract settlement. diff --git a/research/uma/umips/umip-93.md b/research/uma/umips/umip-93.md deleted file mode 100644 index e80a8766..00000000 --- a/research/uma/umips/umip-93.md +++ /dev/null @@ -1,50 +0,0 @@ -| UMIP-93 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add yvUSDC as a whitelisted collateral currency | -| Authors | Pascal Tallarida (pascal@jarvis.network) | -| Status | Approved | -| Created | 09/05/2021 -| Discourse link | https://discourse.umaproject.org/t/add-yvusdc-as-approved-collateral/1060 | - -## Summary - -This UMIP will add yvUSDC, an interest-bearing stablecoin tokenizing USDC deposited in YEARN V2 Vaults, as approved collateral currency.

For example, it will allow us, at Jarvis, to launch new liquidity pools based on yvUSDC (see [UMIP-34](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-34.md). - - - -## Technical Specification - -To accomplish this upgrade, two changes need to be made: - -- The yvUSDC address, 0x5f18c75abdae578b483e5f43f12a39cf75b973a9, needs to be added to the collateral currency whitelist introduced in UMIP-8. -- A final fee of 400 yvUSDC needs to be added for yvUSDC in the Store contract. - -## Rationale - -The rationale behind this change is giving deployers more useful collateral currency options. - - -400 yvUSDC was chosen as the final fee for yvUSDC because this is the practical equivalent to the final fee of already -approved stablecoins. - - -## Implementation - -This change has no implementation other than proposing the two aforementioned governor transactions that will be proposed. - -## Security considerations -yvUSDC bear the centralized risks of USDC and the technical risks of Yearn: yearn's vault are investing depositors' USDC into other protocols in order to generate yield, therefore, in addition to yearn's own smart contract, yvUSDC also bears the risk of the underlying protocols used for generating the yield. - -Although, Yearn's team has quite a conservative risk management and assessment matrix, so the risk is limited. - -Using yvUSDC as collateral for contract deployers and users should be done without considering 1 yvUSDC = 1 USD; yvUSDC is an interest-bearing stablecoin which constantly grows in value. Contract deployers would need to use the yvUSDC/USDC exchange rate. - -A potential added risk for liquidators is that the yvUSDC token can be obtained only by depositing USDC in Yearn V2 Vault system (currently there is not a secondary market for the token). In that case liquidators are exposed to a possible high gas costs, which might dissolve some of the profits from the liquidation itself. One way to mitigate this is to hold a reserve of yvUSDC, which allows generating yield while a liquidation opportunity arrises. diff --git a/research/uma/umips/umip-94.md b/research/uma/umips/umip-94.md deleted file mode 100644 index f9cb9370..00000000 --- a/research/uma/umips/umip-94.md +++ /dev/null @@ -1,57 +0,0 @@ -| UMIP-94 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add UST as a whitelisted collateral currency | -| Authors | Pascal Tallarida (pascal@jarvis.network) | -| Status | Approved | -| Created | 09/05/2021 -| Discourse link | https://discourse.umaproject.org/t/add-ust-as-approved-collateral/1059 | - -## Summary - -This UMIP will add TerraUSD (UST) as approved collateral currencies. This will involve adding the currencies to the whitelist and adding a flat final fee to charge per-request. The proposed final fee is 400 UST per request. - -## Motivation - -UST is a decentralized algorithmic stablecoin pegged to the US dollar, issued on the Terra blockchain and wrapped onto various Blockchain. - -UST has been launched in September 2020, following the success of TerraKRW (KRT), a stablecoin pegged to the Korean Won (KRW). Since launch, UST became the 5th largest stablecoin, right behdind DAI, with a $2 Bn market capitalisation. $360M of UST are currently circulating on the Ethereum Blockchain. - -Unlike other algorithmic stablecoin, UST has been incredibly stable. - -Terra USD(UST) uses an elastic supply to maintain its peg to the USD. As example when there is a high demand for UST and the stable coin is traded above 1 USD, the supply of UST will be increase by minting new UST, thus bringing back down the price to a dollar. Vice versa if there is a shortage in demand for UST, the protocol will buy back UST and will burn in, thus reducing the supply and pushing the price back up to be equal to 1 USD. Also arbitrage opportunities are an incentivization to keep the price at 1 USD. - -The above algorithmic approach is achieved by using LUNA token as collateral for UST. In order to mint a new supply of UST, the protocol will have to burn LUNA tokens. Vice versa if the supply of UST have to be reduced, the protocol will burn UST tokens and mint LUNA tokens. - -It is listed agasint USDT on Bittrex and Kucoin, and in the UST Curve meta-pool (UST+3pool). - -Adding UST as collateral will allow the creation of new synthetic assets backed by this stablecoin.

To construct the UMA/USD price feed, we will calculate the median price between the three data sources used in the UMIP 57: Coinbase (USD), Okex (USDT) and Binance (USDT). - -USD/XXX: TraderMade's APIs provides a free tier API to the price of USD agasint any currency (1,000 queries per month; the price update frequency is below 1 second for the live price, and 60 seconds for the historical price; it also provides subscription model for 30 pounds per month). Forex pair price should then be rounded to 5 decimals. - -#### Specification on historical prices: -- Cryptowatch and TraderMade use a different input format for querying historical data: you need to use Unix timestamp for Cryptowatch, and YYYY-MM-DD-HH:MM for TraderMade. -- Price requests should use the minute price that is nearest and earliest than the price request timestamp. Voters should use the open price of the OHLC period prior or undergoing based on the price request timestamp. Cryptowatch and TraderMade endpoints are queried based on the OHLC period's open time. For example, a request for a Forex pair price at 2021-05-10-21:10:16 should use query for the same period and use the open price as a reference. - -#### Weekend timestamp -Over the weekend or some official holidays the REST API for Forex pair prices does not return any price, but we can request the price of a certain moment before the market close (as ex: the closing price of Friday). - -Due to unavailability of price feed for foreign exchange rates over the weekend or during some official holidays, tokenholders and users will be using the latest known price, which for the weekend is essentially the closing price of Friday. Same goes in a case of a liquidation process - the liquidator should use the last known price (during the weekend this is the closing price of Friday) in order to match with the price on which a synthetic asset was created, if it was created over the weekend. If not the closing price on Friday for a certain asset should be a navigating point in calculating the collateralization ratio of a position and in the liquidation process. - -If a request timestamp takes place on a weekend or any other day the Forex market is closed, voters should use the latest tick as the price. For the weekend that would be the closing price of the asset on Friday and for official holidays this would be the last know price provided by the price feed. - - -## Technical Specification -The definition of this identifiers should be: - - -- Identifier name: EURUMA -- Base Currency: EUR -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: GBPUMA -- Base Currency: GBP -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: CHFUMA -- Base Currency: CHF -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: CADUMA -- Base Currency: CAD -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: JPYUMA -- Base Currency: JPY -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: ZARUMA -- Base Currency: ZAR -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: KRWUMA -- Base Currency: KRW -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: NGNUMA -- Base Currency: NGN -- Quote Currency: UMA - ------------------------------------------ - -- Identifier name: PHPUMA -- Base Currency: PHP -- Quote Currency: UMA - ------------------------------------------ - - -- Source: https://marketdata.tradermade.com and https://cryptowat.ch/ -- Result Pocessing: None -- Input Processing: None.

They are popular with Quantitative Traders, Fintech companies and Institutional customers who require a high quality and trusted feed. Although other price feeds can be used for forex pairs, we'd reccommend using TraderMade price feed. - -For collateral tokens price feed we'd reccommend using CryptoWatch, as it is the most widely used price feed currently on the market. CryptoWatch allows polling for price feeds from various exchanges, which allows getting a price feed even in the case where a certain exchange is in maintance or down due to technical reasons. Also the availability of multiple price feeds from various exchanges gives the opportunity to get a computed median price of a certain collateral token by comparing prices from various exchanges which mitigates the risk of a corrupted price feed. - -## Implementation -To construct UMA/XXX or XXX/UMA price feed, we need to combine two price feeds: -• To get UMA/XXX: we divide UMA/USD by XXX/USD, or multiply it by USD/XXX. -• To get XXX/UMA: we divide 1 by UMA/XXX. - -Note that the FX rate price feeds have already been implemented in UMIPs [29](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-29.md) and [90](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-90.md). The UMAUSD price identifier has already been implemented in [UMIP-57](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-57.md#price-feed-implementation-3). This UMIP simply combines price identifiers from those three UMIPS to arrive at the XX/UMA price identifiers. - -### Example: EURUMA and UMAEUR -- To construct the price for UMA/EUR we will multiply UMA/USD by USD/EUR. -- To construct the price of EUR/UMA we will divide 1 by UMA/EUR. - -#### Steps to construct the live prices: - -As a reference you can look at [UMIP-57](https://github.com/UMAprotocol/UMIPs/blob/master/UMIPs/umip-57.md) as the below described approach has the same implementation. - -Step 1: query prices for UMAUSD: -• Coinbase Pro UMA/USD: https://api.cryptowat.ch/markets/coinbase-pro/UMAUSD/price -• Binance UMA/USDT: https://api.cryptowat.ch/markets/binance/UMAUSDT/price -• OKEx UMA/USDT: https://api.cryptowat.ch/markets/okex/UMAUSDt/price - -Step 2: calculate the median price between the 3 prices - -Step 3: query prices for USD/EUR -• USD/EUR: https://marketdata.tradermade.com/api/v1/live?currency=USDEUR&api_key=api_key - -Step 4: multiply the median price of UMAUSD by USD/EUR to get UMA/EUR or divide 1 by UMA/EUR to get EUR/UMA. - -Step 5: Round the price based on the rounding defined in `Technical specifications` section. - -#### Steps to construct historical prices: -Step 1: query historical prices for UMAUSD for the 10th of May 2021 at 6:03pm: -• Coinbase Pro UMA/USD: https://api.cryptowat.ch/markets/coinbase-pro/UMAUSD/ohlc?after=1620669780&before=1620669780&periods=60 -• Binance UMA/USDT: https://api.cryptowat.ch/markets/binance/UMAUSDt/ohlc?after=1620669780&before=1620669780&periods=60 -• OKEx UMA/USDT: https://api.cryptowat.ch/markets/okex/UMAUSDt/ohlc?after=1620669780&before=1620669780&periods=60 - -Step 2: calculate the median price between these 3 prices. - -Step 3: query historical prices for USDEUR for the 10th of May 2021 at 6:03pm: -• USD/JPY: https://marketdata.tradermade.com/api/v1/minute_historical?currency=USDEUR&date_time=2021-05-10-18:03&api_key=apikey - -Step 4: multiply the median price of UMAUSD by USD/EUR to get UMA/EUR or divide 1 by UMA/EUR to get EUR/UMA. - -Step 5: Round the price based on the rounding defined in `Technical specifications` section. - - -To build UMAGBP prices, you just need to repeat these steps by changing USD/EUR by USD/GBP, etc. - - -### Price feed - liquidations and disputes - -Liquidation and dispute bots should have their own subscription to price feeds. Our price-feed provider’s API documentation can be found [here](https://marketdata.tradermade.com/documentation).

However, anyone deploying a new priceless token contract referencing this identifier should take care to parameterize the contract appropriately to avoid the loss of funds for synthetic token holders. Additionally, the contract deployer should ensure that there is a network of liquidators and disputers ready to perform the services necessary to keep the contract solvent. - -While the price of JPY/USD or any other forex pair does not vary much across various price feed during the weekday, it may be more challenging to get a unified price feed on the weekend: first, while the underlying market is not closed, most of the broker and banks feeding the APIs price feed are; then, for the one providing a price feed, they often add a very big spread, which makes the price of forex pairs vary significantly by source; a way to mitigate it is to use the last price known. - -A consequence to this is the existence of gaps between the last quote on Friday to the first one on Sunday; while such gaps rarely exceed +/-2%, which should not put in danger the collateralization ratio, an exceptional event happening the weekend may create a bigger gap and could, in theory, endanger the collateral ratio; yet, it is very unlikely to see +/-20% gap on JPY/USD, but it is in theory possible. Nevertheless, due to gaps, a larger number of liquidation and disputes may arise on Sunday 9 pm UTC if the collateral ratio was already getting weaker before the week’s end. In order to mitigate this theoretical risk a high collateralization requirement (120%+) should be set or a reserve fund mechanism should be implemented in order to automatically rebalance the collateralization ratio above 100% (in case it falls below 100%), thus making the liquidation process profitable again. \ No newline at end of file diff --git a/research/uma/umips/umip-96.md b/research/uma/umips/umip-96.md deleted file mode 100644 index 9959694d..00000000 --- a/research/uma/umips/umip-96.md +++ /dev/null @@ -1,287 +0,0 @@ -## Headers -| UMIP-96 | | -|------------|------------------------------------------------------------------------------------------------------------------------------------------| -| UMIP Title | Add BNT, vBNT, BAND, SDT, KP3R, CREAM, CHAIN, and ERN as approved collateral currencies | -| Authors | John Shutt (john@umaproject.org), Deepanshu Hooda (deepanshuhooda2000@gmail.com), Britt, Aaron (bitznbrewz), Shawn Hagenah (Hagz48) | -| Status | Approved | -| Created | May 2, 2021 | -| [Discourse Link](https://discourse.umaproject.org/t/add-band-sdt-kp3r-cream-lpool-chain-sand-ern-and-pols-as-approved-collateral-currencies/1054) | | - -# Summary (2-5 sentences) -This UMIP will add BNT, vBNT, BAND, SDT, KP3R, CREAM, CHAIN, and ERN as approved collateral currencies.

We decided to use an application specific governance model to support a wider variety of situations and reduce the burden on UMA voters. - -## Implementation -The code is available here: https://github.com/PrelaunchFinance/VEMP/tree/main/contracts - -Mainnet contracts: - -VariableExpiringMultiPartyCreator: https://etherscan.io/address/0x0548BA0cF38F8e5600b18C4153a89e0E05239647#contracts -VariableExpiringMultiPartyLib: https://etherscan.io/address/0x7e8C45219463e372B3eE216523830cAD0bA92DA8#contracts - -## Security considerations -Few lines of code were added. Therefore the potential surface area for an exploit is low, particularly as we receive feedback from the community and UMA team. However, we may pursue an audit in the future. - -Per feedback from the UMA team we decided to use the Optimistic Oracle for the final price determination, so that the third party DAO address only has the authority to expire the contract but not determine the expiry price. - -We included the updateDAOAddress function to minimize potential issues with the application specific external DAO contract. However, the security of the DAO is important as the VEMP contract could be prematurely or belatedly expired. diff --git a/research/uma/umips/umip-template.md b/research/uma/umips/umip-template.md deleted file mode 100644 index 2ad8a61c..00000000 --- a/research/uma/umips/umip-template.md +++ /dev/null @@ -1,36 +0,0 @@ -This is the suggested template for new UMIPs. -
