2mo TitanHookA fee-collecting hook for token launches that charges a configurable platform fee plus per-token buy/sell taxes on each swap, applies a time-decaying anti-snipe surcharge on buys made within a set number of blocks after launch, and routes all collected fees to the token creator's claimable balance. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 234 2mo RobinVistaHookA Uniswap v4 hook for RobinVista launch pools that charges a configurable trading fee (up to 10%) in the pool's base token regardless of swap direction or exact-in/out type. Fees are collected as PoolManager claims and distributed to five buckets (creator, holders, protocol, burn, flywheel) upon withdrawal. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 228 2mo OGHookPlatform fee hook for OG.fun token launches. On every swap, collects a configurable hook fee plus optional creator buy/sell taxes from the quote token, distributes proceeds to token creators, affiliates (via hookData code), a buyback-and-burn pool, staking, and treasury. Includes decaying anti-snipe surcharges in early post-launch blocks and decaying deployer-dump surcharges in the first 48 hours. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 227 3mo OrynthEthFeeHookCharges a fixed 2% fee exclusively in native ETH on every swap, splitting the fee 50/50 between a registered pool creator and a platform address. Pools must be pre-registered by a designated launcher before initialization; swaps on unregistered pools revert. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 224 2mo LaunchpadHookA token launchpad hook that implements a constant-product bonding curve priced in IMD tokens. Swaps on launched token pools (ETH/coin) are fully consumed in beforeSwap: the ETH leg routes through a canonical ETH/IMD pool, and the IMD proceeds price the coin against a per-coin virtual reserve curve. Creator fees (ETH) and burn fees (IMD) are applied on each trade. Ethereum beforeInitbeforeAddLiqbeforeSwapswapDelta 211 2mo Vvveity Fee Hook V2Charges a flat immutable fee (in basis points) on every swap via beforeSwap, forwarding the fee inline to either a platform address or the token creator, determined by trade direction and token registration. Base beforeSwapswapDelta 209 2mo MixpadHookA Uniswap v4 hook for the Mixpad token launchpad that collects platform swap fees on every trade and splits them between the token creator and treasury, with a configurable portion going to an automatic buyback-and-burn. Applies a decaying anti-snipe surcharge on buys in the blocks immediately after launch and a time-limited linearly-decaying surcharge on sells by the original deployer address. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 209 16mo Clanker Dynamic Fee Hook (Arbitrum)Clanker V4 hook for autonomous token deployment with dynamic fees that adjust based on swap volatility using a tick-based accumulator model. Also includes MEV protection via an optional external module active for the first 2 minutes after pool creation. Arbitrum beforeInitbeforeAddLiqbeforeSwapafterSwap+2 199 3mo PmavHookA Uniswap v4 hook-based token launchpad (pmav.fun V2) that deploys ERC-20 coins with a concentrated bonding curve position, enforces fair-launch rules including a block+1 trading delay, a 2% first-hour buy cap with auto-refund, and a decaying anti-snipe premium. Charges a 1% fee split 70/30 creator/platform. Graduates coins by replacing the curve with a permanently locked full-range position in the same pool. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 195 3mo ERC1967ProxyAn ERC-1967 upgradeable proxy that delegates all Uniswap v4 hook calls to an unverified implementation address. The hook address encodes all 14 permission flags; actual hook behavior cannot be assessed from the proxy-only verified source. Robinhood beforeInitafterInitbeforeAddLiqafterAddLiq+10 189 21mo BunniHookUniswap v4 hook for Bunni v2 concentrated liquidity pools that handles the entire swap lifecycle in beforeSwap using custom Liquidity Density Function math, dynamic surge fees, a TWAP oracle, am-AMM auction-based LVR/MEV recapture, and automated FloodPlain-based rebalancing. Base afterInitbeforeAddLiqbeforeSwapswapDelta 189 3mo SentryStockFeeHookV3Launch hook with a time-decaying dynamic fee (high start → floor) that skims fees from swaps and splits them among creator, treasury, holder reflections (via dividend token notifyReward), and auto-compounding locked full-range LP. A pre-reflection delay window redirects the reflection share to creator/treasury; whitelisted launch wallets pay the floor fee rate. Robinhood beforeInitafterInitbeforeSwapafterSwap+2 186 2mo InstantHookCollects a fixed 1.50% fee on the ether leg of every swap in ether-quoted Uniswap v4 pools, routing proceeds to a per-market fee vault via ERC-6909 claims. The pool's LP fee is overridden to zero, making the hook fee the sole cost of a trade. Robinhood beforeInitafterInitbeforeAddLiqbeforeSwap+3 184 17mo BunniHookCore Uniswap v4 hook for the Bunni v2 protocol. Replaces standard AMM swap execution with custom Liquidity Density Functions (LDFs), dynamic surge-fee pricing, optional am-AMM for fee management, a TWAP oracle, auto-rebalancing via Flood, and a per-pool hooklet plugin system. Base afterInitbeforeAddLiqbeforeSwapswapDelta 176 4mo ClankerHookStaticFeeV2Clanker protocol hook for token-launch pools with directional static LP fees (separate rates for swapping toward vs away from the Clanker token), protocol fee collection via swap delta adjustments, and optional MEV protection module (active for the first 2 minutes post-launch) and pool extension support. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 174 3mo FoundryHookV4R2E2Market-cap-tiered fee hook for a token launch platform.

Exposes price quote functions from the TWAP; pools must be registered by a trusted registrar before swaps are accepted. Robinhood beforeSwapafterSwap 139 3mo LivoSwapHook (V2)Singleton fee hook for Livo-graduated ETH/token pools. Collects LP fees and post-graduation taxes on the ETH leg across all four swap directions, routing them to a treasury fee router and per-token receivers via ILivoToken.accrueFees(). Blocks swaps on non-graduated tokens. Fees are withheld via BeforeSwapDelta or AfterSwapDelta depending on which leg the ETH amount is known. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 139 3mo MixpadHookCollects a platform swap fee on every trade and splits it between the token creator and treasury, with the creator's share further split into a claimable payout and an automatic buyback-and-burn. Applies a decaying anti-snipe surcharge on buys in the first N blocks after launch and a time-limited extra fee on sells from the deployer address. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 128 2mo LaunchHookLaunchHook manages token launch pools with locked liquidity, applying a high anti-snipe fee (up to 99%) that decays over 20 seconds post-launch to a normal 1% rate.

Founders accumulate earnings on-chain and withdraw via claimEarnings(). Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 96 3mo ScaleProxyERC1967 upgradeable proxy for the Scale protocol, delegating hook logic to an upgradeable implementation. The proxy exposes beforeInitialize, beforeAddLiquidity, beforeRemoveLiquidity, beforeSwap, and afterSwap permissions; the implementation source is not verified, so swap behavior could not be fully analyzed. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+1 95 2mo DynamicFeeHookV2Implements a linearly decaying LP fee that starts high at launch and decreases to a steady-state fee over a configurable duration (anti-sniper mechanism). Records an on-chain TWAP oracle after each swap using a cumulative sqrtPrice accumulator. Base beforeSwapafterSwap 93 3mo FriarTierDynamic LP fee hook using a Liquidity Book volatility-accumulator mechanism. Applies an immutable base fee (fixed at deployment per tier) plus a variable surge component based on price displacement across tick buckets. No owner, no admin, no upgradeability; all parameters are frozen at construction. Robinhood afterInitbeforeSwap 93 11mo Wassblaster HookA hook for wASS/memecoin pairs that charges a 1% total fee (0.3% to LPs, 0.7% to the hook) and routes a configurable portion of buys through an in-swap OTC mechanism at the actual pool rate, distributing wASS fee proceeds to stakers and accumulating memecoin fees as OTC inventory. Base beforeInitbeforeSwapafterSwapswapDelta+1 91 2mo LaunchHookFee engine for a permissionless token launchpad. Charges a configurable fee (1% protocol + up to 9% creator add-on, up to 10% total) on every swap, always taken in the pool's quote asset, collected as ERC-6909 claims and settled separately. Includes an optional anti-snipe surge fee that decays linearly post-launch. Liquidity can only be seeded once by the factory and is permanently locked. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 88 3mo GuardHookRestricts pool initialization to the factory address to prevent front-running of pool launch. All swap-time flags are disabled, so the hook is never invoked during trades; the pool fee serves as the creator tax. Robinhood beforeInit 87 2mo AegisHookA Uniswap v4 hook that applies dynamic LP fees via an external fee manager, charges additional hook fees on swaps (split by exact-in/exact-out path), records price oracle observations, and periodically reinvests accumulated fees into full-range liquidity positions. Robinhood afterInitbeforeSwapafterSwapswapDelta+1 86 2mo BlendHookSingleton Uniswap v4 hook that intercepts all swaps on basket/quote pools, settling them at exact NAV by minting or redeeming through BasketVault contracts rather than executing the AMM curve.
