16mo Clanker Dynamic Fee Hook (Unichain)A Clanker-integrated hook that dynamically adjusts LP fees based on price volatility (tick-difference accumulation with decay), charging a base fee plus a variable component scaled by recent price movement. It also extracts a 20% protocol fee on non-clanker token sides of swaps, and temporarily protects newly launched pools via a configurable MEV module for the first 2 minutes post-creation. Unichain beforeInitbeforeAddLiqbeforeSwapafterSwap+2 71 55d SessionHookA Uniswap v4 hook that restricts swaps to regular US stock market hours (9:30–16:00 New York time, Monday–Friday), computing DST transitions on-chain without an oracle. Pool initialization is restricted to an authorized `markets` address and must pair a specific token at zero LP fee. Robinhood beforeInitbeforeSwap 70 2mo AuraHookFee-collection hook for factory-launched tokens that charges buyers a configurable fee plus buy tax, and can drain 100% of the sell-side quote amount from non-creator sellers once a buy-volume threshold is reached, directing collected fees to the token creator. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 70 3mo LunchTaxHookPairImmutableNon-upgradeable Uniswap v4 hook that collects configurable buy/sell taxes on the quote token of each managed pool. Proceeds are distributed to the token creator, platform fee sink, and referrers, with optional launch guards (trading-open delay, max-buy cap, and a decaying launch-window tax rate). Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 70 3mo VampHookA market-cap-tiered tax hook for Vamp Pad ETH/token pools. On each swap it collects a fee (up to 1.25%) scaled by the token's current market cap, then distributes platform and creator shares to configurable treasury addresses.

It enforces immutable liquidity rules, charges fixed protocol fees using beforeSwap and afterSwap return deltas (2% on the ETH/WORDS pool and 1% on WORDS/child-token pools), tracks WORDS reserves as NFT reward weights, burns child-market WORDS fees, and distributes main-pool ETH fees between the treasury and NFT owners.

Base beforeAddLiqafterSwapafterSwapDelta 68 3mo FactoryHookSingleton hook for graduated BCToken pools that computes a volatility-adjusted dynamic fee split between LP positions (via LP-fee override) and a protocol waterfall (via hook deltas).

Fees are taken via BeforeSwapDelta or AfterSwapDelta and forwarded to a factory contract; when the pool manager lacks sufficient balance, fees are parked as ERC-6909 claims and flushed on the next eligible swap. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 62 16mo TokenFabA token launch factory hook that deploys ERC20 tokens and manages them through a bonding curve pool. Once a token's bonding curve supply cap is reached, the hook automatically migrates liquidity to a standard AMM pool, charging a 1% swap fee split equally between creator and platform fee recipients.

External LP is locked until pool graduation. All fee parameters are immutable at deploy. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 61 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.

Robinhood afterInitbeforeSwapafterSwapafterSwapDelta 58 2mo PadHookUniswap v4 hook for the Mixpad token launchpad. Collects a platform fee on every swap, splitting it between the token creator and treasury; a configurable portion is auto-routed to a buyback-and-burn.

Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 57 3mo FriarTierDynamic LP fee hook implementing a Liquidity Book volatility-accumulator surge mechanism on top of an immutable base fee set at deployment. Each deployment represents a distinct, non-configurable fee tier shared by all pools on that hook, with no admin controls, no upgradeability, and no protocol fee. Robinhood afterInitbeforeSwap 57 59d 0xabd5…40c0Runs code on every swap Robinhood beforeSwapafterSwap 56 2mo DopplerHookInitializerA Uniswap v4 pool initializer implementing the Doppler Multicurve bonding curve mechanism for token launches. Distributes liquidity across multiple tick ranges, supports optional dynamic LP fee adjustment via an associated Doppler hook, and enforces a graduation condition when the pool price reaches a target tick. Arbitrum beforeInitafterAddLiqafterRemoveLiqafterSwap+1 56 20mo BunniHookImplements the Bunni v2 AMM protocol as a Uniswap v4 hook. Handles swaps entirely in-hook via a configurable Liquidity Density Function (LDF), with dynamic fees (surge fees and optional am-AMM managed fees), a TWAP oracle, and automated rebalancing via the Flood protocol. Ethereum afterInitbeforeAddLiqbeforeSwapswapDelta 56 2mo AgenEngineHookV2A market engine hook that replaces the LP fee with its own tiered fee structure, collected via BeforeSwapDelta and afterSwapDelta returns based on trade side and size. Enforces configurable per-market trade size bounds (min/max token and quote amounts) and optionally restricts liquidity provisioning to a factory address. Robinhood beforeInitafterInitbeforeAddLiqbeforeSwap+3 55 2mo ZentralCoreFeeHookVolatility-based dynamic fee hook for the Zentral launchpad. Fees scale between a per-pool base and max rate (0.25%–3%) based on previous-swap tick movement, collected in ETH, token, or both per pool configuration. Input-side fees are taken in beforeSwap; output-side fees in afterSwap. Exact-output swaps are rejected; only exact-input swaps are supported. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 55 2mo ModularLaunchpadHookA configurable launchpad hook using universal LP-fee economics: the hook holds the seed LP position and anyone may call harvest() to collect its accrued fees, split 70/30 between creator and protocol. Supports optional anti-snipe buy caps, JIT sandwich defense, creator fee burn, and liquidity-deepening modules; this deployment has no swap-permission flags active. Robinhood beforeInit 55 3mo QuoteAssetCreatorFeeHookV1Charges a fixed 1% fee in the quote token (split 0.9% to the token creator's vault, 0.1% to the launcher) on every swap of registered stock/quote-asset pairs. Uses beforeSwap/afterSwap return deltas to extract fees from both exact-input and exact-output swaps.

Liquidity additions are restricted to an approved position manager. Pool graduation is tracked by checking whether the current tick has crossed a configured graduation tick after each swap. Robinhood beforeInitafterInitbeforeAddLiqbeforeSwap+3 54 2mo GemHookA launch-platform hook for the Gem Factory that collects configurable protocol fees and per-token creator taxes on swaps through registered token/quote pairs. Fees are taken from the quote-token amount in beforeSwap or afterSwap and distributed to token creators as claimable balances. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 54 3mo LaunchHookA Uniswap v4 launchpad hook managing bonding-curve memecoin pools with three fee phases: launch guard (90%–3% decaying anti-sniper fee over ~5s), curve (1% flat until graduation threshold), and graduated (1% flat, pool opens to public LPs). Fees are captured via before/after swap deltas on the quote token and routed to a FeeRouter with an optional referrer extracted from hookData. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 54 3mo RobinhoodArenaFeeHookA post-swap hook for Robinhood Arena launch pools that collects a configurable fee from the output token of each swap and distributes it to multiple recipients via an external ArenaFeeHelper contract.

Requires dynamic-fee pool initialization; pools must be pre-configured with floor, flat, and cap fee bounds before creation. Robinhood beforeInitbeforeSwap 52 2mo SpotA dynamic-fee hook that computes base + surge LP fees via a DynamicFeeManager and charges a configurable protocol fee on each swap (exactIn in beforeSwap, exactOut in afterSwap), minting the fee share to a full-range liquidity manager for reinvestment. Uses a truncated geometric oracle to record price observations and auto-tune fee parameters. Robinhood afterInitbeforeSwapafterSwapswapDelta+1 52 6mo DopplerHookInitializerA Uniswap v4 hook that manages token launches on a multi-segment bonding curve, with dynamic LP fees, optional plugin hooks (DopplerHooks) for custom swap callbacks, and a graduation mechanism that migrates liquidity to a standard AMM once the target tick is reached. Ethereum beforeInitafterAddLiqafterRemoveLiqafterSwap+1 52 12mo Deli Hook (Base)Collects swap fees always in wBLT and forwards them to a FeeProcessor contract, while enforcing that all pools include wBLT as a token and use dynamic LP fees (overriding them to 0 at swap time). Syncs DailyEpochGauge and IncentiveGauge on every swap to support incentive accounting.
