Users can set a target price, and when the pool price reaches the specified price, the Hook automatically executes the order. This enables users to place limit orders directly on Uniswap v4.

Only the bound launcher factory can initialize pools, and fees can only be lowered (never raised) by the creator after launch.

Anyone can call `distribute` to redeem accrued fees, optionally routing payouts through USDG into native ETH via two hookless pool swaps.

Includes JIT liquidity protection via block-based position locks and takes a governance-controlled protocol fee split from the dynamic LP fee.

This ETH variant additionally supports native ETH as currency0. Robinhood beforeInitbeforeSwap 10 2mo DualPoolHookJIT liquidity hook that deploys concentrated LP positions across multiple configurable tick ranges (buckets) before each swap and removes them after, using ERC-4626 vault rehypothecation to earn yield on idle capital between swaps. Pool fee is static (set at deploy time); swaps can be paused per-pool by the owner.

Charges a decaying anti-dump sell tax (linear decay over a configurable block window) plus configurable hook and creator buy/sell taxes on registered token swaps. All collected fees are routed to token creators via a claimable balance mapping. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 10 2mo ForgeHookV4A Uniswap v4 hook for controlled token launches that enforces launchManager authorization for pool initialization and liquidity provision. Collects configurable buy/sell fees via swap deltas and distributes fee shares across platform, creator, rewards, and utility recipients. Remove liquidity and donations are permanently disabled. Ethereum beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+4 10 2mo 0x1b2e…c0ccRuns code on every swap · Can take tokens from swaps Base beforeSwapafterSwapswapDeltaafterSwapDelta 10 2mo CoalaArbitrumHookA Coala launch hook that collects a 1% buy and sell tax on swaps in registered pools. Tax is taken from the specified or unspecified currency via BeforeSwapDelta (beforeSwap) and AfterSwapDelta (afterSwap), minting ERC6909 tokens to the project token address. Arbitrum beforeInitbeforeSwapafterSwapbeforeDonate+2 10 2mo ERC1967Proxy HookAn upgradeable ERC1967 proxy contract that delegates all calls to an implementation address. The hook implements beforeSwap, afterSwap, beforeAddLiquidity, and beforeInitialize, with both beforeSwapReturnsDelta and afterSwapReturnsDelta enabled, indicating it modifies swap deltas. The actual hook logic resides in the unresolved implementation contract. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 10 2mo Frontier FactoryHookSingleton hook governing graduated BCToken pools; blocks swaps until the coin is graduated (`isLPd`), then charges time-decayed volatility-based fees split between LP positions (via dynamic LP fee override) and protocol (via hook delta). The non-LP share is distributed to the protocol treasury, staking vault, and fee recipient via a two-level waterfall. Robinhood beforeInitafterInitbeforeSwapafterSwap+2 10 2mo QuotronFloorHookFee engine for QUOTRON floor pools that overrides LP fees to zero and charges a tiered fee on the stock side via return deltas. During a 6-hour launch window, whitelisted swappers pay 3%; holders of the 100 FCFS reduced-fee spots pay 10%; all others pay 40%. After the window, everyone pays 3%. Each fee is split four ways: ~2/3 to a reflections engine, ~1/6 to a STONKBROKER buy-and-burn pot, ~1/6 to an LP-reinvest pot, and ~5% to a creator address paid directly per swap. Robinhood beforeInitafterInitbeforeSwapafterSwap+2 10 2mo 0x1cc5…0080Runs code on every swap · Sets its own swap fee Base beforeSwap 10 2mo MixpadHookUniswap v4 hook for the Mixpad launchpad that collects platform swap fees on every trade and splits them between the token creator and treasury. Applies a decaying anti-snipe surcharge on early buys and a time-limited surcharge on deployer sells, and routes a configurable share of creator fees into automatic buyback-and-burn of the launched token.

Fees are split between a per-pool creator allocation vault and a platform treasury collector. The hook bypasses fees for the registered allocation vault address. Ethereum beforeInitbeforeSwapafterSwapswapDelta+1 10 3mo InstantLaunchHookCharges a configurable ETH-denominated tax (0–10%) on native ETH/token pools, split between the pool creator and a platform fee recipient. During a brief 4-second anti-snipe window after launch, non-whitelisted traders pay a flat 70% tax instead of the configured rate. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 10 3mo LaunchFeeHookAnti-snipe launch fee hook that overrides the LP fee to 50% for the first 4 minutes after pool initialization, then permanently drops to 3.5%. The fee is applied via dynamic fee override in beforeSwap with no admin controls or setter functions. Robinhood afterInitbeforeSwap 10 3mo LaunchFeeHookApplies a time-based anti-snipe fee to pools: 50% flat fee for the first 4 minutes after initialization, then a permanent 3.5% LP fee floor. Fees are immutable — no admin controls or setters exist. Robinhood afterInitbeforeSwap 10 3mo BasedBidHookRuns code on every swap · Can take tokens from swaps · Sets its own swap fee · Runs at pool creation Robinhood afterInitbeforeSwapafterSwapswapDelta+1 10 3mo BDeFiHookA Uniswap v4 hook that applies buy/sell taxes on swaps and fulfills pending fee obligations using TWAP-based pricing, routing collected fees to registered receivers (LP managers, leaderboard, genesis). Also maintains a truncated geometric oracle for pool observations. Robinhood beforeInitafterInitbeforeAddLiqbeforeRemoveLiq+4 10 3mo SaturnOmnichainV4HookHook for the Saturn Omnichain project with only the afterInitialize flag set. All hook callbacks are pure no-ops returning the selector. An external initializePools() function delegates to an ISaturnOmnichainLiquidityBootstrapper contract to bootstrap liquidity and records the resulting initial tick on-chain. Ethereum afterInit 10 3mo SaturnOmnichainV4HookA minimal Uniswap v4 hook for the Saturn Omnichain protocol. The afterInitialize callback is a no-op; the contract provides an external initializePools() function that delegates to a LiquidityBootstrapper contract to set the initial tick and mark the pool as initialized. Base afterInit 10 3mo SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain project that records pool initialization state via an external liquidity bootstrapper. Only afterInitialize is active, which is a no-op returning the selector with no additional logic. Robinhood afterInit 10 3mo SaturnOmnichainV4HookA hook for the Saturn Omnichain protocol that records the initial pool tick after initialization via a separate liquidity bootstrapper contract. Only afterInitialize is enabled; all swap hooks are no-op stubs, making swap behavior entirely vanilla. Ethereum afterInit 10 3mo SaturnOmnichainV4HookA hook for the Saturn Omnichain project that only implements afterInitialize as a no-op stub. Pool and liquidity setup is handled externally via initializePools(), which calls an ISaturnOmnichainLiquidityBootstrapper to bootstrap positions and record the initial tick. No swap logic is present. Base afterInit 10 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project that uses afterInitialize to support pool setup via an external liquidity bootstrapper contract. It has no active swap, liquidity modification, or donation hooks. Robinhood afterInit 10
