Add AggHook hook on ethereum

[hooklist-generator]

Summary

A Uniswap v4 hook that automatically routes swaps across multiple registered liquidity uniswapV3like pools from Uniswap, Pancakeswap, Sushiswap, Aerodrome, etc. By discovering and executing the most efficient path at transaction time, it allows traders to access deeper aggregated liquidity, improve price execution, and reduce the effects of liquidity fragmentation.

Flags

Address suffix 0xe888 = binary 1110 1000 1000 1000. All 14 bits match the declared flags exactly:

Properties

• dynamicFee: false ✓ — beforeSwap returns a fee override of 0 (mstore(0x40, 0)). Protocol fees are collected via the PoolManager donate() call (_fee() function), not via LP fee override. No updateDynamicLPFee() call present.
• upgradeable: false ✓ — No proxy pattern, no delegatecall, no SELFDESTRUCT. Pool addresses are embedded as immutable bytecode constants.
• requiresCustomSwapData: false ✓ — beforeSwap ignores the hookData bytes calldata parameter entirely; routing uses on-chain pool state and bytecode-embedded pool keys only.
• vanillaSwap: false ✓ — Correct. beforeSwapReturnsDelta is true and beforeSwap executes cross-pool swaps internally (both V3 pools via uniswapV3SwapCallback/pancakeV3SwapCallback and V4 pools via the PoolManager swap selector), fundamentally changing how the swap executes.
• swapAccess: "none" ✓ — beforeSwap only calls _onlyPoolManager() (standard protocol requirement that caller is PoolManager). Unlike beforeAddLiquidity and beforeInitialize, beforeSwap does not call _onlyAdmin(). No restriction on who can initiate swaps.

Metadata

• verifiedSource: true ✓ — Confirmed by source_meta.json.
• chainId: 1 ✓ — Confirmed by Mainnet.sol: PM = 0x000000000004444c5dc75cB358380D2e3dE08A90 (Uniswap v4 PoolManager on mainnet), GAS_TOKEN = 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 (WETH).
• name: "AggHook" ✓ — Matches ContractName from verified source (contract AggHook is Router).
• description ✓ — Accurately describes the aggregation/routing behavior: the hook sorts pools by effective price (_rfq041/_rfq140), routes through up to 10 pools (3 V4 + 7 V3), and handles both V3 callbacks (uniswapV3SwapCallback, pancakeV3SwapCallback) and V4 nested swaps. No audit claims, safety guarantees, or unsubstantiated marketing language.

Conclusion

All flags, properties, and metadata are correct and substantiated by the on-chain source code.
