7mo TokiHookCustom AMM curve hook for fixed-rate Principal Token (PT) trading using a Pendle-style yield curve. Handles its own swap math via beforeSwap with delta returns, blocks direct PoolManager liquidity ops, optionally rehypothecates idle liquidity into ERC4626 vaults, and maintains a TWAP oracle for logarithmic implied rates. Swaps are permanently disabled after PT maturity. Arbitrum afterInitbeforeAddLiqbeforeSwapswapDelta 5 8mo 0x1ea3…4080Runs code on every swap · Sets its own swap fee Base beforeSwap 5 8mo FreeholdHookIntercepts all swaps in creator-registered sDAI/SyntheticFiatToken pools and routes them through the token's mint() and redeem() functions via BeforeSwapReturnsDelta, providing oracle-priced, zero-slippage virtual liquidity with no real liquidity held in the pool. Ethereum beforeSwapswapDelta 5 8mo CumHookDynamic LP fee hook that adjusts fees based on cumulative price impact (CPI) across swaps. Fees scale with directional market imbalance and time-decay between swaps; each pool must be explicitly configured with fee bounds, decay parameters, and illiquidity scale before trading is permitted. Ethereum beforeInitafterInitbeforeSwapafterSwap 5 9mo UniswapV4MigratorHookRestricts Uniswap v4 pool initialization to only the UniswapV4Migrator contract by reverting in beforeInitialize if the caller is not the designated migrator address. Has no swap-related hooks. Base beforeInit 5 9mo TradingFeeHookCollects a 5% trading fee on every swap (0.5% commission to treasury, 4.5% to token creator via RevenueVault), using beforeSwapReturnDelta for exact-input buys and afterSwapReturnDelta for sells and exact-output buys. Pools must be registered by the LaunchVault to have fees enabled; unregistered pools swap without any fee.

Pool creation and liquidity addition are restricted to the ERC20StrategyFactory. Ethereum beforeInitafterAddLiqafterSwapafterSwapDelta 5 10mo Universal Hook (Unichain)A JIT (Just-In-Time) liquidity hook that intercepts swaps via beforeSwap and fulfills them internally at oracle-reported prices through a MerchantController-managed liquidity system. Standard liquidity additions and removals are blocked; only owner-initialized, oracle-whitelisted pools with an approved pair token are supported.

Includes an optional MEV protection module active for the first 2 minutes after pool creation, and restricts liquidity additions during that window. Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 5 12mo UniV4HookSets a dynamic LP fee (2% initially) on pool initialization via afterInitialize, and allows the owner to update the fee at any time via forceUpdateLPFee. Has no swap hooks; fee changes take effect on subsequent swaps through the pool manager's dynamic fee mechanism.

Base beforeInitbeforeAddLiqafterAddLiqbeforeRemoveLiq+6 5 16mo BoardHookToken launchpad hook implementing fair launch periods with temporal gating and optional Merkle-proof allowlisting.

When bonding curve supply is exhausted, the hook automatically removes liquidity and migrates it into a standard AMM pool. A fixed 1% swap fee is collected via afterSwapReturnsDelta and split 50/50 between a creator fee receiver and a platform fee recipient. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 5 17mo TokenFabA bonding curve token launch hook that blocks external liquidity management (beforeInitialize/beforeAddLiquidity/beforeRemoveLiquidity all revert). Newly launched tokens trade on a bonding curve until the supply cap is reached, then the hook automatically migrates liquidity to a standard AMM pool. Each swap incurs a 1% fee split 50/50 between the creator and platform, taken via afterSwapReturnsDelta. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 5 17mo TokenFabA token launchpad hook that deploys new ERC20 tokens on a Uniswap v4 bonding curve pool; once the bonding curve supply is exhausted, it graduates the token to a full AMM pool with two-sided liquidity. Takes a hardcoded 1% fee on every swap, split equally between the token creator and platform fee recipient.

Arbitrum beforeSwapswapDelta 5 20mo Coinbase Verified Hook (Base)A Coinbase-authored access-control hook for Verified Pools that restricts pool initialization, liquidity operations, swaps, and donations to addresses verified by configurable on-chain policies. Also collects an optional configurable bips-based hook fee on swaps via afterSwapReturnsDelta. Base beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 5 21mo FairTradeHookAnti-MEV hook that blocks swaps from owner-blocklisted addresses, reverts same-block swaps from the same sender (sandwich detection), and enforces a configurable per-address timestamp cooldown between swaps. Ethereum beforeAddLiqbeforeRemoveLiqbeforeSwapafterSwap 5 21mo SwapHookObservation hook that counts the number of beforeSwap and afterSwap calls per pool ID. beforeAddLiquidity and beforeRemoveLiquidity are implemented as no-ops that simply return their selector.
