3mo HookenAntiSnipeHookAnti-snipe hook for Hooken launch pools that applies a 50% tax on non-whitelisted buys within a 4-second launch window (routed to protocol treasury), and a cyclic dynamic tax on all other buys and sells (routed to the token creator), always collected in native ETH via BeforeSwapDelta/AfterSwapDelta returns. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 3mo ERC1967ProxyAn upgradeable ERC1967 proxy hook with a beforeSwap permission. Only the proxy contract source is verified; the implementation contract is not available, so actual hook behavior cannot be analyzed. Robinhood beforeSwap 4 3mo MonkeyFeeHookA volatility-based fee hook for Uniswap v4 that charges ETH fees on buys (in beforeSwap) and sells (in afterSwap). The fee scales between a configurable base and max rate (1%–7.3%) based on the previous swap's tick movement, and is sent directly to a per-pool fee recipient on every swap. Only exact-input swaps are permitted. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 3mo GreenTownV4HookA graduation gate hook for GreenTown launchpad tokens that blocks all pool initialization and swaps until a designated migrator has locked graduation liquidity and called openPool(). Once a pool is opened it remains open permanently; the check is per-pool keyed by PoolId. Robinhood beforeInitbeforeSwap 4 3mo NasdankFeeHookPairUniversalA Uniswap v4 hook that charges a configurable fee (in pips) on both swap directions, taken in the designated pair token. Fees are accrued as ERC-6909 claims and distributed between a project treasury (pair token) and a protocol treasury (WETH via a frozen DIRECT/VIA_USDG conversion route). Pools must be registered by an admin-controlled launcher before swaps are permitted. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 3mo PeepsV4TaxHookA meme token launch hook that applies configurable buy/sell taxes via BeforeSwapDelta, distributes tax proceeds to fund, burn, dividend, and liquidity buckets in afterSwap, and blocks third-party LP additions during a configurable anti-farmer lock period. Robinhood beforeAddLiqbeforeSwapafterSwapswapDelta 4 3mo FarmIndexFeeHookVolatility-based dynamic fee hook for ETH/token pairs launched via FarmIndexLauncher. Charges ETH fees on swap input for buys (beforeSwap) and on ETH output for sells (afterSwap), with the fee rate scaling between a configured base and max BPS based on the previous swap's tick movement. Fees are sent directly to the pool's fee recipient on every swap. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 3mo GataraEthHookLaunch hook for ETH-quoted Uniswap v4 pools that charges configurable directional buy/sell fees denominated in native ETH, split among a pool creator, a protocol treasury, and a decaying launch-period cocoon surcharge. Blocks third-party buys in the same block-second as pool initialization to prevent atomic snipe attacks. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 4 3mo MemeRaceHookTimed meme-racing game hook on WETH/meme Uniswap v4 pools. Takes a 1.2% WETH swap fee via beforeSwap/afterSwap deltas (anti-snipe buy fees decay from 100% over 10 blocks), tracks featured Top 3 by net WETH flow, and on round end buys back podium memes from the prize pool into treasury. Swaps require an active game window. Robinhood afterInitbeforeSwapafterSwapswapDelta+1 4 3mo LiquidityGateGates pool initialization to the launchpad address and restricts liquidity additions to the locker or locker-initiated transactions via IMsgSender. Permanently locks all liquidity by reverting any removal attempts with LiquidityLockedForever. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiq 4 3mo BicoLaunchpadV3A bonding-curve launchpad hook that deposits a token's sellable supply as a concentrated liquidity position. When the price walks to the lower bound (curve sold out), afterSwap removes the curve position, deducts graduation fees, and re-deposits locked full-range liquidity in the same Uniswap v4 pool. Robinhood beforeInitbeforeAddLiqafterSwap 4 3mo PmavHookQuotedPmavHookQuoted (pmav.fun V2 quoted variant) is a bonding curve hook for token launches on Robinhood Chain quoted in an ERC20 (USDG/stock tokens). It enforces block+1 anti-snipe, a permanent 2% wallet cap with auto-refund waterfall, a decaying anti-snipe fee premium, and auto-graduates pools to a locked full-range LP position once the raise target is met. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 4 3mo PmavHookQuotedPmavHookQuoted is a bonding curve launchpad and Uniswap V4 hook for pmav.fun. Coins (1B fixed supply) trade on an ERC20-quoted bonding curve with a 1% fee and a permanent 2% wallet cap; when 800M curve tokens are sold the pool graduates in-place to a permanently locked full-range LP position. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 4 3mo PmavHookQuotedA bonding curve launchpad hook that manages token launches through a curve phase with a block+1 trading delay, per-wallet 2% caps, and decaying anti-snipe fees; graduates to a standard 1% LP fee pool when the raise target is met. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 4 3mo BasketHookA Uniswap v4 hook serving as both a factory and trading engine for basket tokens (multi-asset index ERC-20s) paired with USDG. Swaps trigger atomic basket minting (buy) or redemption (sell) by routing through constituent asset markets via Uniswap v3/v4 legs, with fee accrual to a fee auction contract. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+1 4 3mo HoodsHookSingleton ETH-fee hook for hoods.meme pools. Takes a tiered ETH fee (0.25%–1%) on every swap, scaled by fully-diluted market cap, and distributes it between a platform treasury and a per-token creator splitter. Sell exactOut swaps are rejected. Pool LP fee is 0. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 4 3mo PmavHookQuotedBonding curve launchpad factory on Uniswap V4 that creates 1B-supply ERC20 coins paired against an immutable ERC20 quote token (USDG). Manages a concentrated curve position with a 1% fee (70% creator / 30% platform), enforces a permanent 2% per-wallet buy cap with auto-refund, and graduates the coin to a permanently locked full-range position when the raise target is met. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 4 3mo GuardHookRestricts pool initialization to the factory address, preventing front-running by requiring `sender == factory` in `beforeInitialize`. Has no swap-time flags, so swaps execute identically to a standard Uniswap v4 pool with no hook. Robinhood beforeInit 4 3mo LiquidityGateGates liquidity operations on a Uniswap v4 pool: only a designated locker address may add liquidity, and any real liquidity removal (liquidityDelta < 0) is permanently prohibited for all parties. Zero-delta decreases (fee collection) are still permitted. Robinhood beforeAddLiqbeforeRemoveLiq 4 3mo BackedFeeHookA fee-taking hook that charges a fixed 3% swap tax in native ETH (currency0) on all swaps, routing the full fee to a vault address. Fee collection is split between beforeSwap (ETH-specified swaps) and afterSwap (ETH-unspecified swaps) using return deltas; non-ETH pools pass through untaxed. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 3mo GateFeeGraduateHookA shared v4 hook for meme token launches that gates external liquidity (only the launcher may add LP via a one-shot per-pool gate), charges a 1% ETH fee on all swaps using the return-delta mechanism, and automatically marks a pool as graduated once net ETH inflow reaches 4 ETH. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 4 3mo DirectV4StakingFeeHookCollects a fixed WETH fee on every token/WETH pool swap, distributing 30% to the pool creator, 15% to platform token stakers via a staking vault, and 55% to the treasury. Fees are extracted via beforeSwap and afterSwap return deltas using poolManager.take(). Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 4 3mo LootHookA Uniswap v4 hook that charges a fixed 1.5% ETH fee on both buy (ETH→token) and sell (token→ETH) swaps. Fees are always taken in ETH to avoid token sell pressure, then distributed on-chain to token holders (via DividendToken.fundPot), the pool creator, platform, and ops addresses. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 3mo PumpFeeHookA Uniswap v4 hook for token launches that charges tiered creator and protocol fees on swaps based on the token's market cap, and overrides LP fees dynamically per tier. Fees are taken from the input currency in beforeSwap (exactInput) or afterSwap (exactOutput) and held for distribution via skim(). Robinhood afterInitbeforeSwapafterSwapswapDelta+1 4 3mo UnipadHookV4Shared, ownerless anti-snipe hook that applies a decaying dynamic LP fee per pool: 50% for the first 2 blocks after initialization, 20% for blocks 2–4, and 1% thereafter. Each pool's fee schedule is independent, starting from its own initialization block. Robinhood beforeInitbeforeSwap 4 3mo LaunchpadHookA launchpad hook that gates swaps until a scheduled activation time and collects trading fees in WETH via swap deltas. Fees follow a time-decaying anti-snipe schedule or a market-cap-decaying curve, split between protocol, creator, and partner, with the creator's share routed into buyback-burn, auto-LP, token reflections, and WETH dividends. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 4 3mo LaunchHookA shared multi-pool hook that applies a linearly decaying dynamic LP fee (from a configurable high start rate to a lower end rate over a set time window) to deter sniping at token launch. Each pool gets its own fee schedule keyed by pool ID, seeded at initialization and updated per-swap by the owner-configured schedule. Robinhood afterInitbeforeSwap 4 4mo NoxaHookA shared Uniswap v4 hook for meme coin fair-launches that charges a fixed 1% tax on the base asset (WETH) side of every buy and sell, minting the collected tax as ERC-6909 claims to the launched token contract. Pool creation is restricted to factory-registered pools only. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 4 4mo HoodseaFeeHookShared hook for native-ETH/token pools that charges a 1.5%–3.5% fee on every swap, with optional anti-sniper linear decay from 80% at launch. Fees are taken from ETH input on buys (beforeSwap delta) and from ETH output on sells (afterSwap delta), then routed to a per-pool recipient address registered by a factory. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 4mo GoldFunHookMemecoin launchpad hook implementing a constant-product bonding curve for token launches. During the curve phase, swap math is fully overridden and fees (protocol + referral + creator) are skimmed from the ETH side. At graduation, raised ETH and unsold tokens are seeded as locked full-range liquidity in the same pool. Post-graduation, the hook collects the same fee split from normal AMM swaps via beforeSwap/afterSwap return deltas. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 4 4mo PensionTaxHookCollects a fixed 4% tax (400 bips) on ETH involved in swaps: deducted from ETH-input swaps via beforeSwapReturnsDelta and from ETH-output swaps via afterSwapReturnsDelta, forwarding the collected ETH directly to an immutable pension fund vault address. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 40d NoOpA minimal hook that emits a swap event in beforeSwap and collects a fixed 10 bps protocol fee on every swap's unspecified (output) currency in afterSwap via a return delta, routing fees to a hardcoded recipient address (AEON_FEE_RECIPIENT). Robinhood beforeSwapafterSwapafterSwapDelta 3 40d SHREDDERPermissionless Uniswap v4 dynamic-fee hook for SHRED markets. Adjusts fees using trade size, volatility, repeated flow and price reversals. Shares adaptive fees with LPs and delivers paired-asset revenue to the PULP Pool contract. Non-upgradeable, with no owner or custom router calldata requirement. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 3 55d Ctrl Immutable Launch HookImmutable, non-proxy launchpad hook for Ctrl tokens paired with native ETH. Collects a fixed 1% ETH fee using swap return deltas for creator rewards, referrals, treasury and a graduation bounty. Empty swap hookData is accepted; attribution data is optional. Core LP fee is zero. Only the initial factory seed liquidity can be added, and its position is permanently locked. Graduation at 4.2 ETH net principal releases the bounty without migrating liquidity. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 3 56d DescendingFeeHookA Uniswap v4 hook that charges a descending anti-snipe fee: starting at a high rate (up to 99%) held briefly after launch, then parabolically decaying to a configured steady-state rate. The fee is taken in the input currency via hook deltas and accrued as ERC-6909 claims in the PoolManager, collectible by the launcher. LP fee is always zero; donations are disabled. Robinhood beforeInitbeforeSwapafterSwapbeforeDonate+2 3 58d LaunchFeeHookA launch tax hook that deducts a configurable fee (in basis points) from the gross input of each exact-input swap, accumulates the tax on-chain per pool and asset, and allows anyone to collect accrued fees into an immutable reward vault. Robinhood beforeInitbeforeSwapafterSwapswapDelta 3 58d DescendingFeeHookAnti-snipe descending swap fee hook that charges a high fee (up to 99%) at pool launch, holds it briefly, then parabolically decays to a creator-set terminal rate; fees are collected as ERC-6909 claims in the PoolManager and released to the launcher via collect(). LP fee is always static zero. Robinhood beforeInitbeforeSwapafterSwapbeforeDonate+2 3 58d MinimalDiamondCallBackProxyAn ERC-2535 Diamond proxy hook built on the Crane framework that delegates calls to registered facets by function selector. The hook has beforeSwap with delta return capability, plus beforeInitialize, beforeAddLiquidity, beforeRemoveLiquidity, and beforeDonate flags; actual swap logic resides in unverified implementation facets. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+2 3 2mo LaunchpadV4HookToken launchpad hook that collects fees denominated in the payment token (fixed 1% base fee plus up to 10% creator tax) via BeforeSwapDelta and AfterSwapDelta. Tracks pool graduation when price crosses a configured tick and restricts liquidity additions to a designated position manager. Robinhood beforeInitafterInitbeforeAddLiqbeforeSwap+3 3 2mo HookrModularHookV6WthA modular Uniswap v4 hook that applies a dynamic LP fee and performs on-chain arbitrage recapture (MEV correction) on every qualifying swap by dispatching a nested correction swap through a pool-configured executor. Swap accounting is delegated via delegatecall to an immutable, codehash-verified accounting kernel; trusted routers may supply signed hookData for enriched payer/recipient routing. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 3 2mo RobinhoodMixedFeeHookUniswap v4 hook for Robinhood Launchpad V2. Collects dividend fees in the configured base token while collecting creator, protocol, and referral fees in the swap's unspecified currency. Enforces a maximum total fee of 9.9%. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 3 2mo ApeLaunchHookA launchpad hook that gates pool creation to pre-registered pools (via beforeInitialize) and restricts liquidity additions to authorized callers (launchpad or locker) using transient storage (via beforeAddLiquidity). Swaps are not intercepted; the full launch fee is embedded in the PoolKey LP fee rather than charged by this hook. Robinhood beforeInitbeforeAddLiq 3 2mo AgiV2MemeHookSingleton Uniswap v4 hook for graduated AGI v2 launchpad pools that collects a fee cut (hookFeeBps + creatorTaxBps) on every swap via afterSwap, deducting the fee from the pool manager's flash-accounting ledger and accruing it to per-pool pending balances, which can later be swept and split between protocol, buyback-and-lock vault, and creator. Robinhood beforeInitafterSwapafterSwapDelta 3 2mo LustHookCollects swap fees for enrolled tokens, applying a configurable flat rate and an elevated peak rate during an early launch window. Fees are taken directly from swap amounts via BeforeSwapDelta/AfterSwapDelta and accumulated for distribution to registered token devotees. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 3 2mo JadeHookA swap fee hook for a token launchpad that charges a configurable base fee on swaps for registered tokens, with an elevated rush fee during an initial block window after token registration. Fees are accrued to token maker addresses and can be claimed via the hook contract. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 3 2mo WavesCurveHookA bonding-curve launchpad hook that runs a presale phase where buys and sells are priced against a virtual-reserve curve; once the curve fills, anyone can call graduate() to deploy permanently locked wide-range liquidity and the pool trades as a standard Uniswap v4 AMM. Robinhood beforeInitbeforeAddLiqbeforeSwapswapDelta 3 2mo LpGuardHookRestricts pool initialization and liquidity addition to a single allowlisted launcher address while leaving swaps fully permissionless. Ensures the protocol is the sole LP by construction via `beforeInitialize` and `beforeAddLiquidity` guards; the launcher is bound once post-deploy via a one-shot `setLauncher` call gated to an immutable binder address. Robinhood beforeInitbeforeAddLiq 3 2mo BobHookBobHook collects swap fees for factory-registered token stations, applying a higher snap fee during a configurable early block window after listing and a flat fee thereafter. Accumulated fees are attributed to designated patrons and redeemable via redeem/redeemAll. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 3 2mo GladeHookA fee-collecting hook that charges a configurable basis-point fee (capped at 5%) on swaps involving registered tokens, takes the fee directly from the PoolManager, and distributes it to token wardens (owners) via a per-token harvest balance that wardens can withdraw. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 3 2mo WingsHookA swap fee hook for tokens enlisted by a WingsFactory. Charges a configurable fee on swaps, applying an elevated "snare" rate for early buys within a configurable block window after token listing. Accrued fees are stashed per pilot (token creator) and claimable at any time. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 3
