feat(mainnet): add 1inch protocol (Aggregation Router v6 + Aqua)

[dak-agent]

Summary

Adds mainnet/1inch.jsonc for 1inch — the DEX aggregator + gasless, intent-based Limit Order Protocol, plus 1inch's Aqua shared-liquidity layer and its SwapVM execution engine.

Requested via the 1inch/limit-order-protocol repo; the Aqua/SwapVM contracts were added after review feedback.

Addresses

Contract	Address	Notes
AggregationRouterV6	0x111111125421cA6dc452d289314280a0f8842A65	Also serves Limit Order Protocol v4 (swaps + limit orders).
Aqua (registry)	0x1111113CCf1426A8E30e2bfF5E005d929bF6a90a	1inch's self-custodial shared liquidity layer.
SwapVM router	0x111111338c5091E8440b67B168bAe16a668AC0De	Programmable execution engine for Aqua (EIP-712 domain 1inch SwapVM v1.0).

All three are deterministic deployments that share the same address on every 1inch-supported chain, including Monad.

Verification (chainId 143):

• AggregationRouterV6 — deployed bytecode contains the 1inch Aggregation Router EIP-712 domain and has live transactions. Currently unverified on the block explorer (source not yet published on MonadVision).
• Aqua and SwapVM router — both source-verified on MonadVision (perfect match); contract names AquaRouter and AquaSwapVMRouter, imported from @1inch/aqua / @1inch/solidity-utils. Addresses match the official 1inch/aqua README ("Only interact with these two contracts. Anything else is not Aqua.").

Categories

• DeFi::DEX Aggregator (primary)
• DeFi::DEX (Aqua shared-liquidity AMM)
• DeFi::Intents
• DeFi::Trading Interfaces

Notes

• python scripts/validate_protocol.py --network mainnet passes (no duplicate/canonical-address collisions).
• The AggregationRouterV6 router is unverified on the explorer, so the automated contract-verification workflow flags it — expected for 1inch's canonical router; it does not affect address correctness. The two Aqua contracts are fully verified.
