2mo DualPoolHookJIT liquidity hook that deploys concentrated LP positions across configurable tick ranges before each swap and removes them after, with idle assets rehypothecated into ERC-4626 vaults between swaps. Fee is static (set at pool creation via PoolKey.fee); hookData is ignored on swaps. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+1 30 2mo AdvancedFeeHookV5Collects a configurable swap fee (up to 10%) in afterSwap, splitting it between a platform treasury and per-pool creator payees; portions of the creator share may be burned or reinvested as single-sided liquidity. Pool initialization is gated to a designated launcher address. Base beforeInitafterSwapafterSwapDelta 30 2mo CrestHookA fee hook for Crest factory-launched tokens. On buys, applies a combined protocol fee, per-token buy tax, and a time-decaying anti-snipe fee. On sells, non-creator sellers are charged 100% of quote proceeds as a fee routed to the token creator's claimable balance; the token creator may sell without fee.

Pool initialization is gated to factory-registered pools only via beforeInitialize.

Exact-output sells are rejected. Pools must be registered by a factory before fee logic activates.

Tax proceeds are routed to configurable sinks (burn via buyback-and-burn, holder reflection, auto-LP deepening, creator, and extra wallets). Tracks price-multiple milestones ("Chad Levels") per pool. Base afterInitbeforeSwapafterSwapswapDelta 29 59d LaunchpadHookUniswap v4 hook for launchpad pools that restricts pool initialization to a designated launchpad address (via afterInitialize) and emits a PoolSwap event on every swap for off-chain indexing. No hook deltas are taken and swap execution is otherwise unmodified.

Collects platform swap fees on every trade and splits them between the token creator and a treasury. Applies a decaying anti-snipe surcharge on buys in the first N blocks post-launch and a time-limited deployer-dump surcharge on sells. Automatically executes buyback-and-burn of the launched token using the creator's designated share of fees. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 29 3mo FlowHookV3A USDG-denominated tax hook for token/USDG pools. On every swap it takes a configurable fee (plus an anti-snipe time-decaying surcharge) in USDG via beforeSwap/afterSwap return deltas, then routes proceeds across five buckets: holder baskets, LP auto-add above spot, treasury, token buyback-and-burn, and referral payouts, with a tiered platform cut split between a burn pot and a platform wallet.

Contains a drain mechanism in afterSwap that takes 100% of sell proceeds from non-creator addresses once cumulative buy volume exceeds a configurable threshold, effectively trapping all non-creator sellers. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 28 3mo EthCreatorFeeHookV2Shared Uniswap v4 hook that applies a configurable ETH-denominated swap fee (1%–10%, fixed at pool registration) on native ETH/token pools. The total fee is split between the token creator and an immutable Launcher treasury (fixed 0.10% share), accruing as ERC-6909 claims redeemable by creator or Launcher. LP fee is zero; no token transfer tax. Ethereum beforeInitbeforeSwapafterSwapswapDelta+1 28 3mo PmavHookQuotedBonding-curve token launch hook (pmav.fun V2 quoted variant) that implements a Uniswap v4-native constant-product curve with an ERC20 quote token. Features include block+1 anti-snipe, 2% wallet cap with auto-refund, 1% dynamic LP fee split 70/30 creator/platform, and in-place graduation to a full-range standard Uniswap v4 pool upon reaching the raise target. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 28 3mo BagsV4HookShared hook for all Bags pools enforcing full-range-only, permanently-locked liquidity, zero LP fee, and a 2% hook fee on the WETH leg of every swap. Fees accrue per-pool and are swept to a platform vault (50%) and a creator fee share contract (50%), with an optional partner cut carved from the protocol half. Robinhood beforeInitbeforeAddLiqafterAddLiqbeforeRemoveLiq+4 28 5mo LaunchHookLendingA shared Uniswap v4 hook for token launches that skims a dynamic swap fee (1%–0.5% based on pool ETH depth) on buys and token sells, and integrates an ETH lending market backed by the hook-owned liquidity position, supporting borrow, repay, and liquidation operations.

Fees are accrued per registered pool and collected by an immutable factory contract. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 27 2mo LaunchpadHookCollects a fixed-rate fee on every swap for registered launchpad tokens, splitting proceeds between the token creator, platform treasury, and up to three referral tiers. Fees are extracted via beforeSwap/afterSwap delta returns and accumulated in pull-based claimable balances for ETH and ERC-20 quote tokens. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 27
