3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project that registers the afterInitialize flag but implements it as a pure no-op. The contract exposes a separate initializePools() function that calls a LiquidityBootstrapper to bootstrap liquidity and records the resulting initial pool tick in contract state. BSC afterInit 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. Robinhood beforeSwap 13 6mo V4GasDetectHookA honeypot hook that unconditionally allows buy swaps (zeroForOne=true) but blocks real sell transactions by reverting when gasleft() is below 55M. 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. Ethereum beforeSwapafterSwapafterSwapDelta 13 7mo EMADynamicFeeHookEMA-based dynamic fee hook for Uniswap V4.

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. Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 13 9mo BVCC Dynamic Fee Hook (Base)An advanced dynamic fee hook by BlockVenture Chain Capital that adjusts LP fees based on gas price, price volatility, and 24-hour trade volume, while applying anti-bot cooldown penalties for repeated swaps. It also collects a small protocol fee on each swap output via afterSwapReturnsDelta.

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.

Ethereum beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 12 4mo V4PermissionedSwapsA Uniswap v4 hook that restricts swaps to an owner-managed allowlist of approved sender addresses, reverting any swap from an unapproved sender with `SenderNotAllowed`. BSC beforeSwap 12 5mo BracketHookBracketHook is the central contract for the TheCup protocol, managing 48 country-token pools across two AMM regimes: a bonding curve phase (hook handles all swap math via custom virtual-reserve AMM and a 1% protocol fee) and a graduated phase (standard v4 AMM with 1% protocol fee plus an optional 9% elimination tax on sells of knocked-out country tokens). A per-block price-impact cap (5%) is enforced as a sandwich protection mechanism. Ethereum beforeAddLiqbeforeRemoveLiqbeforeSwapswapDelta 12 5mo IndexHookA hook for IndexToken pools that gates swaps and liquidity additions/removals to owner-approved pools, supports dynamic LP fees with zero-fee overrides for index token self-swaps and custom hook fees for other swappers, and tracks index token reserves in pools for burn coefficient accounting.
