Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 14 2mo SurgeHookA token-launch hook that applies configurable hook fees, creator buy/sell taxes, and time-decaying anti-snipe fees to registered tokens, extracting fees from swap amounts via BeforeSwapDelta/AfterSwapDelta and routing them to token creators. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 14 3mo LaunchpadHookCollects ETH fees on every ETH/token swap, splitting proceeds between the token creator and a treasury address, with optional referral cuts distributed from the platform share. Tracks net ETH volume via a factory contract to support token graduation logic. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 14 3mo HoodsHookSingleton ETH-fee hook for hoods.meme token pools. Takes a market-cap-tiered ETH fee on each swap (max 1% of ETH moved), accruing fees separately for a treasury and a per-token creator splitter; fees are pulled later so no external call occurs in the swap path. Sell-exactOut swaps are rejected. Fee schedule is factory-snapshotted at pool launch and immutable thereafter.

It has no swap-time logic; all hook callbacks are no-ops. Robinhood afterInit 14 3mo LaunchHookLaunchHook charges a fixed 1% fee on ETH/token swaps: for ETH→token buys, it takes the fee from the ETH input via beforeSwap delta; for token→ETH sells, it takes the fee from the ETH output via afterSwap delta. Fees are forwarded to a factory contract (set once by a governor) via depositFees for creator/platform distribution. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 14 4mo ReflectionFeeHookA fixed 2% swap fee hook for graduated reflection-token pools. It collects ETH fees via return-delta callbacks in beforeSwap (for ETH-specified swaps) and afterSwap (for token-specified swaps), forwarding fees to the factory's per-token creditGraduatedFee() bucket. Pool creation is restricted to the factory's graduator contract via beforeInitialize.

Collects a configurable percentage fee from swap output via afterSwapReturnsDelta, with optional reputation-based fee tiers that discount fees for higher-reputation agents. Base afterInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 14 8mo Liquid Launch HookAccess-controlled initialization hook for a liquid launch system. Only strategies authorized via a factory may initialize pools. In beforeSwap, automatically converts accumulated protocol fees to the pool's preferred token (token0 or token1) via nested swaps on the same pool; fee claiming is permissionless but always routes to the strategy's designated fee recipient.

During fair launch, it fills buy-side swaps from a one-sided position and optionally enforces Merkle-proof whitelisting. After launch, it captures swap fees and distributes them to creators, protocol, inspirers, and referrers via delta manipulation. Base beforeInitbeforeAddLiqafterAddLiqbeforeRemoveLiq+6 14 21mo BunniHookBunni protocol's central Uniswap v4 hook that handles swaps using custom liquidity density functions and its own swap math. Implements dynamic surge and TWAP-based fees taken via BeforeSwapDelta, an am-AMM mechanism for LVR/MEV recapture, a TWAP oracle, and auto-rebalancing via FloodPlain.

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.

The fee decays linearly from a configurable start (up to 80%) to a steady-state end (default 1%) over a configurable window (default 10 s) to deter opening-block snipers; exactOut swaps revert during this window. Liquidity additions are vault-only; principal removals are permanently locked. Optionally gates buys to NFT holders and locks sells for a presale period.

Accumulated fees are stored as a claimable bounty for each token's designated captain and can be harvested at any time. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 13 2mo RewardHookCollects a fee (3% base, up to 20% during a 5-minute launch window) on the quote-token side of every swap via before/afterSwap return deltas, then splits the accrued fees between a holder distributor contract, a protocol fee recipient, and a buyback wallet.

Fee rates (between 0.1% and 10%) are configured per pool at registration by the token creator and cannot be changed afterward. Ethereum beforeInitbeforeSwapafterSwapswapDelta+1 13 2mo VelvetHookUniswap v4 hook for the Velvet token launchpad that collects fees on swaps using return deltas. Buy swaps are charged a configurable hook fee plus a per-token buy tax; sell swaps by non-creator addresses have their entire quote output taken as fee, effectively restricting selling to the token creator only. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 13 2mo JoltHookA Uniswap v4 hook for the Jolt token launchpad that collects protocol and creator fees on swaps via BeforeSwapDelta/AfterSwapDelta. Includes an anti-snipe mechanism that charges elevated fees for early buys within a configurable number of blocks after token launch, with fees routed to token creators and claimable on-demand. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 13 2mo FluxHookFluxHook collects protocol and creator fees on swaps via BeforeSwapDelta/AfterSwapDelta, routing them to claimable balances. It applies a configurable anti-snipe fee multiplier during the initial blocks after token launch.

Supports per-token fee parameters, optional anti-snipe and deployer-dump taxes, and automatically executes buyback-and-burn of accumulated fees using the pool. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 13 2mo CashCatQuoteFeeHookA singleton Uniswap v4 hook shared by CashCat launch pools that charges a quote-leg fee (up to 10%) on every swap, minting proceeds as ERC-6909 claims to an immutable liquidity locker, and latches a graduation milestone when the locked position's paired-currency value meets a configured threshold. Pool creation is restricted to the CashCat launchpad and requires a zero LP fee. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 13 3mo CircusFeeHookCharges a fixed 1% fee on the quote asset for every swap in graduated Circus launchpad pools. Distributes fees between the token creator and protocol, with a configurable portion compounded back into the pool's permanently locked full-range liquidity position.
