3mo LunchTaxHookImmutableA non-upgradeable Uniswap v4 hook for ETH-paired token launches that collects configurable buy/sell taxes (up to 20% per side) via BeforeSwapDelta and AfterSwapDelta, with optional launch guards including timestamp-based trading delays, decaying opening taxes, and per-transaction buy caps. Collected ETH is distributed to token creators and a platform address. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 46 3mo RuneMarketHookA Uniswap v4 hook that gates pool initialization to authorized addresses, enforces per-pool pause controls settable by an OPERATOR_ROLE admin, collects a configurable percentage fee on swaps via afterSwapReturnsDelta, and notifies an IOrderManager of tick movements after each swap to settle limit orders. Robinhood beforeInitafterAddLiqafterRemoveLiqbeforeSwap+2 46 2mo StockFeeHookImmutableFee hook for stock-paired (TOKEN/<stock>) Uniswap v4 launch pools. Charges a fixed fee on the stock/quote leg across all four swap directions, accumulating as ERC-6909 claims. A permissionless claimFees() converts accrued stock fees to WETH via Uniswap V3 (TWAP-guarded slippage floor) and distributes as native ETH across a fixed 4-way split: dev, treasury, buyback, and token mechanism. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 45 4mo RampHookA shared Uniswap v4 hook for bonding curve pools that applies dynamic LP fees: an elevated anti-snipe tax during a configurable window after launch, falling back to a per-pool or global platform fee. Liquidity additions are restricted to an owner-managed allowlist of approved callers.

During the curve phase, the hook serves swaps from its own inventory against virtual reserves; upon reaching the graduation threshold, it atomically seeds a permanent full-range CLMM position and thereafter collects protocol fees on all swaps. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 41 2mo TripoolsAntiSnipeHookA shared Uniswap v4 hook for Tripools launch pools that enforces a 6-second anti-snipe window (50% tax routed entirely to treasury for non-whitelisted buys) and a dynamic tiered tax schedule for buys and sells, splitting fees between the pool creator and protocol treasury, always settled in ETH.

Only pools initialized by the authorized strategy contract are taxed. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 38 2mo SettlePermissionHookGates Uniswap v4 pool initialization to a permissioned settle adapter via a one-shot authorize(poolId) allowlist; unauthorized initializations revert. Liquidity operations after initialization are unrestricted. Has no swap hooks. Robinhood beforeInit 38 2mo DriftHookA Uniswap v4 hook for token launches that collects fees on swaps via swap deltas — combining a protocol fee, an optional creator buy/sell tax, and a time-decaying anti-snipe surcharge on early buys. Collected fees are credited to the token creator and claimed via a pull-payment mechanism. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 38 3mo FlowHookV3A Uniswap v4 hook for USDG-paired pools that taxes buy and sell swaps, routing fees to holder, LP, treasury, buyback/burn, and referral buckets via delta interception. An anti-snipe decay fee is applied to buys shortly after pool launch. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 38 3mo CashCatGraduationHookSingleton hook for the CashCat launchpad that restricts pool initialization to the launchpad (beforeInitialize) and monitors post-swap prices to set a one-way graduation latch when a launch token's paired-currency principal reaches a configured threshold (afterSwap).

Each swap pays a 1% fee on the hXMAX leg via BeforeSwapDelta/AfterSwapReturnsDelta, split between a per-launch fee recipient and the treasury; external liquidity is blocked until the curve empties, at which point remaining assets are permanently locked in a dead-address v4 position.

On buys, charges a combined platform fee and per-token buy tax from the quote amount. On sells, non-creator sellers are charged 100% of the swap output as a fee, effectively blocking sells for anyone except the token creator. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 37 2mo CreatorFeeHookA launchpad fee hook that takes a fixed percentage of each swap's output (TOTAL_FEE_BPS), splitting it 70/30 between the token creator and the protocol treasury via a shared fee engine. Pools must be WETH pairs and can only be created by the authorized factory. Also supports multi-token LP rewards via a juice mechanism using V4-style fee-growth accounting. Robinhood beforeInitafterSwapafterSwapDelta 37 3mo QuiverV4HookShared policy hook for Quiver V4 pools that gates token purchases via EIP-712 signed vouchers with per-buyer cumulative allocation limits. Restricts liquidity addition to the designated launcher during the bootstrap phase, and blocks all buys via access-controlled pools unless the buyer holds a valid signed voucher. Robinhood beforeInitbeforeAddLiqbeforeSwap 37 3mo LaunchpadHookA Uniswap v4 hook that restricts pool initialization to a single designated launchpad address, preventing front-running of pool creation for token launches. It is not in the swap path and runs only once per pool, at initialization. Robinhood beforeInit 37 2mo TestHookA minimal test hook that implements stub liquidity callbacks (beforeAddLiquidity, afterAddLiquidity, beforeRemoveLiquidity, afterRemoveLiquidity) that return the correct selectors without performing any logic. Has no swap hooks and no state mutations.

Only exact-input swaps are permitted; exact-output swaps revert. Pool registration is restricted to a single authorized factory address. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 35 2mo ERC1967Proxy HookA Uniswap v4 hook deployed as an ERC1967 upgradeable proxy. The implementation contract is not verified, so the full hook logic cannot be analyzed. The address bitmask indicates beforeSwap with delta return, beforeInitialize, and beforeAddLiquidity permissions. Robinhood beforeInitbeforeAddLiqbeforeSwapswapDelta 35 3mo LaunchpadHookCollects a configurable percentage fee on every swap for registered launchpad token pools, splitting proceeds between the token creator and platform treasury, with optional referral rewards distributed via an external registry.
