5mo CurveHookA bonding-curve AMM hook that manages swaps between a FIFA token and CountryToken ERC-20s using a virtual constant-product formula. Fully intercepts swap execution via beforeSwapReturnsDelta, minting or burning CountryToken supply on each trade while burning a 5% FIFA fee. Standard liquidity add/remove and donate operations are all blocked. Base beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+2 48 5mo CurveHookA custom bonding curve AMM hook for FIFA/Country token pairs using a virtual reserve formula to price buys and sells. Charges a 5% fee per swap (burned), fully replaces pool liquidity mechanics (all direct add/remove liquidity and donate operations revert), and gates trading behind a phase-activation flag set by an authorized pack opener. Base beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+2 48 5mo BracketHookA Uniswap v4 hook implementing a dual-regime AMM for a World Cup bracket protocol: a virtual-reserve bonding curve for early-stage trading, transitioning to a standard v4 pool with protocol fees and elimination taxes (up to 10% on sells of eliminated teams) after graduation. Ethereum beforeAddLiqbeforeRemoveLiqbeforeSwapswapDelta 48 17mo CreatorCoinHookA Zora protocol hook for creator coin pools that collects LP fees on every swap, converts them to a backing currency via multi-hop paths, and distributes market rewards to the creator (including triggering vested coin claims) and other recipients. Base afterInitafterSwap 48 9mo ZoraV4CoinHookZora Coin hook that initializes Doppler multi-curve liquidity positions on pool creation, charges a dynamic LP fee each swap, and in afterSwap collects accrued fees, converts them to a backing currency, distributes market rewards, and fills limit orders if the price tick moved. Base afterInitbeforeSwapafterSwap 47 18mo UniswapV4KEMHookA swap hook that requires a signed off-chain quote in hookData for each swap, validating exchange rate, nonce, and expiry against a designated quote signer. Excess output beyond the signed maximum exchange rate is captured as EG tokens minted as ERC-6909 claims in the PoolManager, claimable by designated accounts. Arbitrum beforeSwapafterSwapafterSwapDelta 47 2mo HookrModularHookV6Modular Uniswap v4 hook with per-pool pluggable module stacks managed via a stack registry.

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 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. Robinhood beforeAddLiqbeforeSwap 46 2mo LiqpadLaunchHookFactory-gated launch pool hook for B20/VVV token pairs. Collects a 1% fee on each swap: B20 (launch token) fees are burned via the token contract, while VVV fees are routed to an immutable FeeRouter that splits 70% to the token creator and 30% to the protocol. Only pools registered and initialized by the factory may be swapped. Base beforeInitbeforeSwapafterSwapswapDelta+1 45 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 17mo TokenFabToken launch platform implementing a bonding curve that automatically transitions to a two-sided AMM pool once the bonding curve supply is fully purchased. Charges a 1% fee on swaps (split 50/50 between creator and platform), and only permits swaps where the launched token amount is the specified side. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 45 6mo LaunchHookLaunchHook is the fee-collection hook used by the Tickr launchpad. It charges a flat 2% fee on every swap (taken from input ETH on buys via beforeSwap and from output ETH on sells via afterSwap) and splits it 50/50 between the token's creator — the holder of the corresponding TickrOwner NFT — and the platform. Fee constants and the creator/platform split are immutable; the only governor action is a one-time setFactory(...) binding. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 44 2mo VectisHookA shared hook for all Vectis pools that restricts pool initialization to the LaunchFactory address and liquidity additions to the Locker address. Swaps are fully unrestricted; the hook has no swap flags, no dynamic fee, and no delta modifications. Robinhood beforeInitbeforeAddLiq 43 59d DiemCatLaunchHookA token launch hook that seeds initial liquidity and applies a time-decaying snipe-protection fee during a configurable window after launch. Token-side fees are burned to a dead address; quote-side fees are split between creator and platform.

Base beforeInitbeforeAddLiqbeforeSwapafterSwap+2 42 5mo RampHookA Uniswap v4 hook for bonding curve pools that enforces a dynamic LP fee returned in beforeSwap (with an elevated anti-snipe fee during a configurable window after each pool's first liquidity event), and restricts liquidity additions to an owner-managed allowlist of approved callers. Base beforeAddLiqbeforeSwap 42 2mo RallyHookA token launch hook that runs a virtual constant-product bonding curve. 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 beforeInitafterSwap 38 4mo WhitelistHookA Uniswap v4 hook that restricts swaps to whitelisted addresses. 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. Ethereum beforeSwap 38 27d HookeMemeHookA single-hook meme launchpad managing bonding curves for meme tokens paired with hXMAX. 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. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+3 37 2mo SomprazHookA Sompraz launchpad hook that collects fees on swaps of registered tokens. On buys, charges a combined platform fee and per-token buy tax from the quote amount.
