Add AggHook hook on ethereum

[hooklist-generator]

Summary

Routes swaps through a hardcoded set of 3 Uniswap v4 pools and 6 V3-compatible pools, sorted on-the-fly by effective sqrtPrice. Handles exactIn and exactOut in both directions, returns a BeforeSwapDelta that fully settles the exchange. Liquidity additions and pool initialization are restricted to a hardcoded admin address.

Properties

• dynamicFee: false ✅ — beforeSwap returns a zero fee override (mstore(0x40, 0) in the return assembly). The _fee() function performs a donate-based fee collection but does not call updateDynamicLPFee() and does not set a dynamic LP fee override.

• upgradeable: false ✅ — source_meta.json confirms "proxy": false. No proxy pattern, delegatecall, or mutable implementation address found in source.

• requiresCustomSwapData: false ✅ — The beforeSwap function accepts bytes calldata hookData but completely ignores it. All routing logic is driven by hardcoded pool data and on-chain sqrtPrice reads. Swaps work without any custom hookData.

• vanillaSwap: false ✅ — Correct. The hook has beforeSwapReturnsDelta = true and actively intercepts and reroutes the entire swap through external pools, returning a BeforeSwapDelta that fully settles the exchange. This is mandatory false.

• swapAccess: "none" ✅ — beforeSwap only enforces _onlyPoolManager() (verifying msg.sender == PoolManager), which is a protocol invariant rather than user-facing access control. No allowlist, governance flag, or temporal gate on swaps.

Metadata

• chainId: 1 ✅ — Matches ethereum in chains.json.
• name: "AggHook" ✅ — Matches contractName from source metadata.
• verifiedSource: true ✅ — Confirmed by source_meta.json.
• description ✅ — All claims substantiated by source:
  • "3 Uniswap v4 pools and 6 V3-compatible pools" → V4_POOLS_LEN = 3, V3_POOLS_LEN = 6 in Config.sol.
  • "sorted on-the-fly by effective sqrtPrice" → _rfq041()/_rfq140() in Quoter.
  • "exactIn and exactOut in both directions" → four routing functions (_exactInput041, _exactInput140, _exactOutput041, _exactOutput140).
  • "returns a BeforeSwapDelta that fully settles the exchange" → explicit assembly return with BeforeSwapDelta in Router.
  • "Liquidity additions and pool initialization restricted to a hardcoded admin address" → beforeAddLiquidity and beforeInitialize both call _onlyAdmin().
  • No marketing, audit, or promotional language.

All flags, properties, and metadata are accurate and consistent with the on-chain source code.
