2mo GlassBoxHookA Uniswap v4 launchpad hook with authorized pool creation and a mandatory dynamic LP fee. beforeSwap enforces a per-pool trading-start timestamp and applies a linearly-decaying anti-snipe LP fee override. afterSwap collects a configurable protocol fee (in bps) from swap output, routes it to a configurable fee sink, and awards Prism points per swap. Robinhood beforeInitafterInitbeforeSwapafterSwap+1 26 2mo FlashHookFLASH v2 protocol hook for WETH-rooted token ecosystems. Routes buys through an OTC order book and AMM aggregator, charges dynamic sell taxes (including price-impact taxes), and distributes proceeds to stakers, pool creators, and protocol treasury. Requires governance to activate a directional protocol fee before any swaps are permitted. Base beforeInitbeforeSwapafterSwapswapDelta+1 26 2mo BlazeHookBlazeHook charges configurable buy and sell fees (in basis points) on swaps for tokens registered by the factory. It takes fees as BeforeSwapDelta/AfterSwapDelta from the quote token, routes them to the token creator, and applies a time-decaying anti-snipe surcharge during the first N blocks after launch. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 26 2mo AdvancedFeeHookV3A token launchpad fee hook for the BaseStonk platform that collects configurable swap taxes in afterSwap, distributing proceeds among a platform treasury, creator payees, a buyback-and-burn mechanism, and optional single-sided liquidity re-injection. Pool initialization is restricted to a privileged launcher address. Base beforeInitafterSwapafterSwapDelta 26 3mo LaunchpadHookA Uniswap v4 launchpad hook that collects a configurable fee (up to 1%) on every swap in registered token pools, splitting proceeds between the token creator, the platform treasury, and up to three referral tiers. Tracks cumulative quote volume per token to signal graduation milestones. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 26 5mo GitlawnchHookSkims a flat 1% fee on exact-input swaps, taking the fee directly into a Locker contract that splits it 80% to the token creator and 20% to the platform. Pools are created with LP fee 0, making this the sole trading fee mechanism. Base afterInitbeforeSwapswapDelta 26 11mo ZoraV4CoinHookUniswap v4 hook for Zora Coins that collects LP fees from multiple positions on every swap, converts them to a backing currency via multi-hop swaps, and distributes rewards to creators, referrers, and the protocol. Supports limit order filling and liquidity migration to new hook implementations. Base afterInitbeforeSwapafterSwap 26 14mo BoardHookA Uniswap v4 hook implementing a token launch platform with a fair launch mechanism that fills purchases from a dedicated position, enforces time-gated access control (pre-launch block), optional Merkle-proof whitelisting, and distributes swap fees across protocol, creator, inspired, and referral recipients. Base beforeInitbeforeAddLiqafterAddLiqbeforeRemoveLiq+6 26 19d Ring FewV2 Shell Hook (WETH)Aggregator hook that routes swaps through FewV2 pairs using Ring-wrapped tokens, bypassing native v4 liquidity. An owner-controlled allowlist (with timelock for new additions) restricts which origin tokens can be registered; a guardian or owner can pause swaps. Ethereum beforeInitbeforeSwapswapDelta 25 2mo LaunchTaxHookCharges a 1% swap tax on launchpad pools, always denominated in the pool's quote token, split 50/50 between the launchpad deployer and the pool token creator. Only the registered strategy contract can initialize pools with this hook; the tax is taken via BeforeSwapDelta or AfterSwapDelta depending on which swap leg is the quote currency. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 25 2mo NexusHookA token-launch platform hook that charges configurable buy/sell fees and a block-based anti-snipe tax on registered tokens, taking fees directly from swap amounts via BeforeSwapDelta/AfterSwapDelta and routing them to token creators as claimable balances. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 25 4mo LittleJohnBondingHookA bonding-launch Uniswap v4 hook extending LittleJohnHook with a graduation milestone: once ETH absorbed (derived from post-swap sqrt price and fixed launch liquidity) reaches a threshold, emits BondingGraduated. Only the factory's initial liquidity add is permitted per pool; all subsequent adds revert. Fees are taken via return-deltas and minted as ERC-6909 native-ETH claims to LpLockerV4. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 25 5mo LiquidGuardUniswap v4 hook that collects a configurable basis-point fee on the RARE token side of every swap, routing collected fees to a designated fee distributor contract. Uses beforeSwap when RARE is the specified currency and afterSwap when RARE is the unspecified currency. Ethereum beforeInitbeforeSwapafterSwapswapDelta+1 25 10mo BVCC Dynamic Fee Hook (BNB)Dynamically adjusts LP fees per swap based on gas price levels, price volatility, and 24-hour trading volume, with an anti-bot cooldown penalty for frequent swappers. Also collects a small hook fee from swap output amounts via afterSwapReturnsDelta. BSC afterInitbeforeSwapafterSwapafterSwapDelta 25 17mo CreatorCoinHookA Zora protocol hook for creator coin pools that collects LP fees after each swap, converts them to a backing currency via multi-hop swaps, and distributes rewards to the creator and protocol. On pool initialization, it mints multiple liquidity positions and, on each swap, also triggers creator vesting. Base afterInitafterSwap 25 17mo TokenFabA bonding curve token launchpad hook that blocks external liquidity and enforces a progressive price curve for newly launched ERC-20 tokens. Once the bonding curve supply is exhausted, the hook automatically migrates liquidity to a standard AMM pool and extracts a 1% swap fee on the base-token side, split 50/50 between creator and platform. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 25 3mo ClankerHookStaticFeeV2A Clanker protocol hook that sets separate static LP fees for buying vs. selling the clanker token, applying them dynamically via updateDynamicLPFee on each swap.

On every swap, collects LP fees, converts them to a backing currency, and distributes rewards. Features a dynamic launch fee decaying from 99% to 1% over 10 seconds post-creation, and triggers Zora limit order book fills on each swap. Base afterInitbeforeSwapafterSwap 24 11mo Aquinas Hook (Base)Restricts Uniswap v4 pool initialization to factory-authorized Safe addresses for Aquinas DAOs, preventing frontrunning of LP initialization by requiring the caller to be pre-approved by the Aquinas factory. Base beforeInit 24 2mo SpotUniswap v4 hook with oracle-based dynamic fee adjustment, full-range liquidity management, and fee reinvestment. Uses a truncated geometric oracle to track tick movement and adjusts surge fees accordingly. Charges both a declared protocol fee and an undisclosed additional 0.10% surcharge on every swap. Robinhood afterInitbeforeSwapafterSwapswapDelta+1 23 2mo ZiaFeeHookA Uniswap v4 hook that enforces keeper-configurable dynamic LP fees (up to 1%) and collects a bounded hook fee (up to 0.25%) in the swap's specified currency, accruing ERC-6909 claims redeemable only to an immutable treasury address. Robinhood beforeInitbeforeSwapswapDelta 23 3mo ZeroHookFee-collection hook for the Zero.family token launchpad. On each swap involving a registered token, it extracts a configurable basis-point fee from the ETH side of the trade using BeforeSwapDelta and AfterSwapDelta, forwarding the collected fee to the factory contract for distribution to token creators. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 23 3mo CashCatQuoteFeeHookA shared Uniswap v4 hook for all CashCat launchpad pools that charges a configurable swap fee (up to 10%) always in the pool's quote currency via v4 return-delta accounting. Fees are taken in beforeSwap for specified-quote swaps and afterSwap for unspecified-quote swaps, minted as ERC-6909 claims to a locker. Pool creation is gated to the CashCat launchpad; afterSwap also records a cosmetic graduation milestone based on post-swap price. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 23 3mo UniswapV4KEMHookQuote-gated Uniswap v4 hook that requires a cryptographic signature from a designated quote signer for each exact-input swap. Validates exchange rate bounds and nonce in beforeSwap; in afterSwap, captures any output exceeding the signed maximum exchange rate by minting ERC6909 tokens to itself, claimable by authorized accounts. Robinhood beforeSwapafterSwapafterSwapDelta 23 3mo LootHookFee-taking hook that skims 1.5% of every swap in ETH. On buys (ETH→token), fees are claimed as ERC-6909 ETH credits in beforeSwap and redeemed in afterSwap or via a permissionless collect(); on sells (token→ETH), fees are taken from the ETH output in afterSwap. Fees are split among token holders (via DividendToken.fundPot), creator, platform, and ops. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 23 3mo ClankerHookStaticFeeV2Clanker v2 hook that applies configurable static LP fees with separate rates per swap direction (clanker-in vs. paired-token-in), collects protocol fees via BeforeSwap/AfterSwap return deltas, and supports optional MEV module (temporary high-fee anti-MEV window) and pool extension integrations.
