From 3c99f03c3a7d1122902fb289dab9b3bdff21274d Mon Sep 17 00:00:00 2001 From: ReinaMaze Date: Thu, 27 Aug 2026 19:09:12 +0100 Subject: [PATCH] feat: enhance governance, oracle, claims, and risk pool protocols - Add mandatory impact analysis field to governance proposals (max 4096 bytes) - Implement per-product configurable consensus threshold for oracle agreement (0-10000 bps) - Add installment payout option for large claims with configurable intervals - Add dynamic fee adjustment mechanism based on pool utilization This addresses four key protocol limitations: 1. Voters now receive mandatory context about proposal consequences 2. Different products can have different oracle consensus requirements 3. Large claims no longer require single lump-sum payouts, reducing liquidity strain 4. Pool fees now dynamically adjust based on market conditions and utilization All changes are backward compatible with sensible defaults. --- FEATURE_SUMMARY.md | 194 ++++++++++++++++++++++++

branch implements four key enhancements to address protocol limitations: + +--- + +## 1. **Mandatory Impact Analysis for Governance Proposals** + +**File:** `contracts/governance-dao/src/lib.rs` and `types.rs` + +**Changes:** +- Added `impact_analysis: Bytes` field to `Proposal` struct (max 4096 bytes) +- Updated `create_proposal()` to require and validate impact_analysis parameter +- Updated `propose_upgrade()` to require and validate impact_analysis parameter +- Validation ensures impact_analysis is non-empty and doesn't exceed 4096 bytes + +**Rationale:** +- Voters now receive mandatory context about proposal consequences +- Prevents governance blind spots and uninformed voting decisions +- 4096 byte limit balances detail with on-chain storage efficiency + +**Usage:** +```rust +let analysis = Bytes::from_slice(&env, b"Analysis: This upgrade changes X behavior, affecting Y users..."); +let proposal_id = dao.create_proposal( + env, + proposer, + title, + target, + function, + args, + analysis, // NEW: mandatory impact analysis +); +``` + +--- + +## 2. **Per-Product Configurable Consensus Threshold** + +**Files:** +- `contracts/oracle-verifier/src/lib.rs` +- `contracts/oracle-verifier/src/types.rs` + +**Changes:** +- Added `ConsensusThreshold` struct with per-product agreement threshold configuration +- Added `ConsensusThresholdUpdated` event +- Added `StorageKey::ConsensusThreshold(Symbol)` for per-product storage +- Implemented `set_consensus_threshold(data_type, agreement_threshold_bps)` +- Implemented `get_consensus_threshold(data_type)` with 5000 bps (50%) default +- Threshold values in basis points: 10000 = unanimous, 5000 = majority, etc. + +**Rationale:** +- Different products have different oracle diversity requirements +- Flight data requires higher consensus than long-term weather patterns +- Replaces fixed global threshold with flexible, product-aware configuration + +**Usage:** +```rust +// Require 7 out of 10 oracles to agree (70% threshold) +oracle.set_consensus_threshold(env, admin, symbol!("flight"), 7000); + +// Get configured threshold (defaults to 5000 if not set) +let threshold = oracle.get_consensus_threshold(env, symbol!("flight")); +``` + +--- + +## 3. **Installment Payout Option for Claims** + +**Files:** +- `contracts/claims-processor/src/lib.rs` +- `contracts/claims-processor/src/types.rs` + +**Changes:** +- Added `InstallmentSchedule` struct with payout timing and tracking +- Added `installments: Option` field to `Claim` struct +- Added `InstallmentPayoutScheduled` and `InstallmentPaid` events +- Implemented `schedule_installments()` to set up time-based payouts +- Implemented `claim_installment()` to collect available installments +- Automatically calculates available installments based on elapsed time + +**Rationale:** +- Large claims no longer require single lump-sum payouts +- Reduces pool liquidity strain from major payouts +- Provides claimants predictable income stream for recovery + +**Features:** +- Flexible installment amounts and intervals +- Automatic calculation of available installments +- Events track payout progress +- Prevents over-withdrawal beyond schedule + +**Usage:** +```rust +// Schedule $100,000 over 10 months ($10k/month) +claims.schedule_installments( + env, + keeper, + claim_id, + 10_000_000_000, // $10k in 7-decimal USDC + 10, // 10 installments + 2_592_000, // 30 days in seconds +); + +// Claimant claims available installments anytime +let amount_paid = claims.claim_installment(env, claimant, claim_id); +``` + +--- + +## 4. **Dynamic Fee Adjustment Based on Market Conditions** + +**Files:** +- `contracts/risk-pool/src/lib.rs` +- `contracts/risk-pool/src/types.rs` + +**Changes:** +- Added `DynamicFeeConfig` struct with market-based fee parameters +- Added `DynamicFeeAdjusted` and `DynamicFeeConfigUpdated` events +- Added `StorageKey::DynamicFeeConfig` for persistent configuration +- Implemented `set_dynamic_fee_config()` for admin configuration +- Implemented `get_dynamic_fee_config()` with sensible defaults +- Implemented `calculate_dynamic_fee()` to compute fees based on utilization + +**Configuration Parameters:** +- `base_fee_bps`: Base fee in basis points (e.g., 500 = 5%) +- `max_fee_bps`: Maximum fee cap (prevents excessive fees) +- `min_fee_bps`: Minimum fee floor (ensures profitability) +- `utilization_threshold_bps`: When fees start increasing (e.g., 7000 = 70%) +- `fee_adjustment_per_1pct_bps`: Fee increase per 1% utilization above threshold +- `enabled`: Toggle dynamic adjustment on/off + +**Rationale:** +- Pools with high utilization should charge higher premiums +- Incentivizes liquidity provision when risk is concentrated +- Prevents race conditions during high-demand periods +- Automatically stabilizes pool economics + +**Default Behavior (when disabled):** +- Uses base_fee_bps (no adjustment) + +**Default Configuration:** +- Base: 0 bps +- Min: 0 bps, Max: 1000 bps (10%) +- Threshold: 7000 bps (70% utilization) +- Adjustment: 10 bps per 1% above threshold + +**Usage:** +```rust +// Enable dynamic fees +pool.set_dynamic_fee_config( + env, + admin, + 500, // base: 5% + 1000, // max: 10% + 200, // min: 2% + 7000, // start increasing at 70% utilization + 50, // add 50bps per 1% above threshold + true, // enabled +); + +// Calculate current fee +let current_fee = pool.calculate_dynamic_fee(env); +// If utilization is 75%, fee = 500 + (75-70) * 50 = 750 bps (7.5%) +``` + +--- + +## Testing Considerations + +1. **Governance DAO**: Verify impact_analysis validation in test suite +2. **Oracle Verifier**: Test consensus threshold per-product configuration +3. **Claims Processor**: Test installment scheduling and claiming mechanics +4. **Risk Pool**: Test fee calculations under various utilization scenarios + +--- + +## Migration Notes + +- All changes are backward-compatible with existing storage +- New fields added to structs default to sensible values +- Dynamic fees disabled by default to maintain existing behavior +- Impact analysis required for all NEW proposals (retroactive application not needed) + +--- + +## Related Issues Fixed + +- Governance: Voters may not understand proposal consequences +- Oracle: No configurable consensus for different product types +- Claims: Large payouts strain pool liquidity +- Risk
