Only applies to pools containing tokens registered by the ResearchFactory. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 2mo StockFeeHookImmutableA fee hook for stock-paired TOKEN/&lt;stock&gt; launch pools on the LaunchFair V2 platform. Charges a fixed fee on the quote (stock) leg of every swap via BeforeSwapDelta/AfterSwapDelta return values, accrues fees as ERC-6909 claims, then permissionlessly converts them stock→WETH on Uniswap V3 and distributes the proceeds in native ETH across creator, treasury, mechanism, and buyback recipients. No admin surface; all parameters are constructor immutables.

Includes a decaying anti-snipe surcharge on buys in the blocks immediately after launch, a time-limited surcharge on deployer sells, and auto-executes a buyback-and-burn of the launched token using a configurable portion of the creator's fee share.

A creator-configured fraction of the creator's fee share is earmarked for automatic buyback-and-burn of the launched token. Applies a decaying anti-snipe surcharge on buys in the blocks immediately after launch and a time-limited surcharge on sells from the original deployer address.

Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 4 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.

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 0xad3c…8080Runs code on every swap · Sets its own swap fee Robinhood beforeSwap 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 0x3013…5440Runs code on every swap · Runs at pool creation Robinhood afterInitafterAddLiqafterSwap 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.

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.

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.

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.

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
