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. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 41 2mo MixpadHookFee-collection hook for the Mixpad token launch platform. Charges a configurable swap fee on every trade, splits it between the token creator and treasury, applies a decaying anti-snipe surcharge in blocks immediately after launch and a time-limited surcharge on deployer sells, and automatically executes buyback-and-burns using a portion of creator fees.

Swaps are blocked until all LP positions for the token are initialized. Ethereum beforeInitafterInitbeforeAddLiqbeforeRemoveLiq+4 40 3mo PmavHookA meme coin launchpad hook (pmav.fun v2.2) that implements a bonding curve via a concentrated Uniswap v4 position, enforces a permanent 2% wallet cap with fill-to-cap semantics, charges a 1% fee split 70/30 between creator and platform, and graduates coins to a permanently locked full-range pool when the curve is exhausted. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 40 17mo BunniHookBunni v2 concentrated liquidity hook that handles swap execution entirely via BeforeSwapDelta using a Liquidity Density Function (LDF). Supports surge fees, am-AMM fee management for MEV/LVR recapture, a TWAP oracle, and automated pool rebalancing via Flood Protocol.

Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 39 2mo TripoolsAntiSnipeHookA Uniswap v4 hook for Tripools token launches enforcing a 50% anti-snipe tax for the first 6 seconds post-launch and a cycling tiered tax schedule on buys (every 4 trades) and sells (every 6 trades). ETH fees are split 20% to the protocol treasury and 80% to the token creator via TripoolsFeeLocker.

Permanently locks liquidity removal by reverting all beforeRemoveLiquidity calls. Ethereum beforeRemoveLiqafterSwap 39 11mo TokiHookCustom AMM hook implementing Pendle-style yield trading for Principal Tokens on Uniswap v4. Computes swaps against a custom curve in beforeSwap, returning a delta, with support for ERC4626 rehypothecation, a TWAP oracle, and curator-controlled pause and pool expiry. Arbitrum afterInitbeforeAddLiqbeforeSwapswapDelta 39 11mo CornersHookStaticFeeA Corners protocol hook that manages Uniswap v4 pools with two configurable static LP fees (one for buying the "corners" token, one for selling it), collects a 20% protocol cut of each swap fee, and runs an optional MEV-protection module during the first 2 minutes after pool creation. Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 39 12mo Aegis v3 Hook (Unichain)A dynamic AMM hook that adjusts LP fees based on market volatility using a truncated geometric oracle with surge fee mechanism, enforces tick movement caps to limit price manipulation, and automatically reinvests protocol fees into full-range liquidity positions.

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 StockPadHookFee engine for StockPad's Uniswap v4 pools. Charges a configurable basis-point tax on the pair-side of each swap, distributed to registered token coin contracts. Features a linearly-decaying anti-snipe surcharge (starting at 99%) for the first 20 seconds after pool launch. Undeliverable fees are held as ERC-6909 claims and flushed on the next swap. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 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).

It checks `tx.origin` against an external `ISwapWhitelist` contract in `beforeSwap`, reverting with `SwapperNotWhitelisted` for non-whitelisted callers. No modification to swap execution occurs beyond access control.

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
