3mo 0xa00d…e880Runs code on every swap · Gates who can add liquidity · Runs at pool creation Robinhood beforeInitbeforeAddLiqbeforeSwap 13 3mo Uni20HookA beforeSwap-only Uniswap v4 hook that automatically triggers LP fee harvesting via an immutable IUni20FeeLocker contract before each registered pool swap. Harvesting failures are caught with try/catch so they cannot block user trades. No hookData is required and no swap deltas are modified. Ethereum beforeSwap 13 3mo 0xcb4d…f0c4Runs code on every swap · Can take tokens from swaps · Sets its own swap fee · Runs at pool creation Robinhood beforeInitafterInitbeforeSwapafterSwap+1 13 4mo V4GasDetectHookA honeypot hook that blocks real sell transactions by checking gasleft(): buys always succeed, sells are allowed only when gas remaining exceeds 30M (typical of simulations/eth_call), and revert on real user transactions with normal gas. Users who buy tokens cannot sell them.

Simulated sells (which use the full block gas limit) appear to succeed, deceiving users into buying tokens they cannot sell in real transactions. Ethereum beforeSwap 13 6mo InuPegHookA Uniswap v4 hook that imposes a trade tax on each swap — 2.5% on buys (2% to a rewards vault, 0.5% to a deployer address) and 2% on sells (ETH forwarded to the vault) — via afterSwapReturnsDelta. On buys it mints NFTs for the recipient per whole INU token unit received (capped at 3 per swap); on sells it burns NFTs LIFO from the seller's inventory.

Calculates swap fees using Exponential Moving Average of price, with 30-step fee schedule (0.01%-3.00%) and 300-block anti-JIT protection via tx.origin. No owner, no admin functions, fully immutable. Arbitrum afterInitbeforeAddLiqbeforeRemoveLiqafterRemoveLiq+2 13 8mo ZoraV4CoinHookUniswap v4 hook for Zora Coins that creates multi-curve liquidity positions on pool initialization. On every swap, collects LP fees from all positions, swaps them to a backing currency, and distributes rewards. Applies a time-decaying dynamic launch fee (99% to 1% over 10 seconds) and fills Zora limit orders when ticks cross. Base afterInitbeforeSwapafterSwap 13 8mo ClankerHookStaticFeeA Clanker factory hook that launches ERC-20 tokens into Uniswap v4 pools with configurable static LP fees per trade direction (clanker-buy vs. clanker-sell). On every swap it sets the dynamic LP fee via updateDynamicLPFee, collects a protocol fee by modifying the swap delta, auto-claims LP locker rewards, and optionally runs a time-limited (2-minute) MEV protection module.

It also collects a small protocol fee on each swap output via afterSwapReturnsDelta. Base afterInitbeforeSwapafterSwapafterSwapDelta 13 10mo Auto Liquidity Generator HookLiquidityGenHook collects configurable buy and sell WETH taxes on swaps via BeforeSwapDelta and AfterSwapDelta, accumulates them, and automatically re-invests into the pool as full-range liquidity once a threshold is reached. A platform fee is taken before the liquidity add. Ethereum beforeInitafterAddLiqafterRemoveLiqbeforeSwap+3 13 11mo CornersHookStaticFeeA Uniswap v4 hook for the Corners protocol that applies asymmetric static LP fees per pool based on swap direction (corners token vs. paired token), takes a 20% protocol fee on each swap by manipulating BeforeSwapDelta/AfterSwapDelta, and optionally runs an MEV protection module during the first 2 minutes after pool creation. Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 13 11mo NFTStrategyHookManages ETH/token pools for NFTStrategy NFT collections on Uniswap v4. Takes a time-decreasing buy fee (starting at 99%, decreasing 100 bps/minute to a floor of 10%) and a fixed 10% sell fee via afterSwapReturnsDelta, distributing proceeds 80% to the NFT collection, 10% to a protocol token buyback, and 10% to a fee address. Ethereum beforeInitafterAddLiqafterSwapafterSwapDelta 13 15mo BoardHookA token launchpad hook that manages fair launch pools for newly issued tokens. It enforces a temporal trading gate (tokens cannot be swapped before their scheduled launch time), supports optional Merkle-proof whitelisting during the fair launch window, burns unsold supply at fair launch close, and distributes swap fees to protocol, creator, referrer, and inspired-fee recipients. Base beforeInitbeforeAddLiqafterAddLiqbeforeRemoveLiq+6 13 18mo TokenFabA Uniswap v4 hook implementing a bonding curve token launch platform. Deploys new ERC20 tokens with configurable multi-chunk liquidity curves backed by a base token, collects a 1% swap fee split equally between creator and platform fee receivers, and automatically graduates tokens to a standard full-range AMM pool when the bonding curve supply is exhausted. Base beforeInitbeforeAddLiqafterSwapafterSwapDelta 13 20mo FairTradeHookA Uniswap v4 hook that blocks swaps from addresses on an owner-maintained blocklist; beforeAddLiquidity and beforeRemoveLiquidity are implemented as pass-throughs with no additional logic. Ethereum beforeAddLiqbeforeRemoveLiqbeforeSwapafterSwap 13 20mo Graduation Hook (Base)Restricts pool initialization to a designated Moxie bonding curve address, ensuring Uniswap v4 pools can only be initialized through the authorized bonding curve as part of a token graduation process.

Restricts liquidity additions and removals to the wrapper contract during maintenance windows.

Fee rates are set at token registration time and capped at 5%. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 12 2mo EchoHookA token launch hook for factory-registered tokens that charges configurable buy fees and sell drain fees (defaulting to 100%) in the quote currency, taken via BeforeSwapDelta and AfterSwapDelta. Accumulated fees are tracked per token creator and claimable via claimFees or claimAllFees. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 12 2mo SpotUniswap v4 hook that applies dynamic fee overrides via beforeSwap lpFeeOverride, records tick observations via TruncGeoOracleMulti, and reinvests collected fees via a FullRangeLiquidityManager. On every swap, an additional undisclosed 0.10% fee (AGGRESSIVE_SURGE) is unconditionally extracted from the input amount on top of any disclosed hook fee. Robinhood afterInitbeforeSwapafterSwapswapDelta+1 12 2mo MoonHookA token launch platform hook that charges configurable BPS fees on swaps for registered tokens by taking from the swap delta. Applies an elevated snipe tax on buys during the first N blocks after launch; accrued fees are claimable by token creators. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 12 2mo MomoHookA Uniswap v4 hook for the Momo token launch platform that collects protocol fees on swaps in registered token pools.
