3mo SaturnOmnichainV4HookHook for the Saturn Omnichain project that records the initial tick after pool initialization via an external liquidity bootstrapper. Only afterInitialize is active; all swap and liquidity callbacks are no-ops that return their selectors unchanged. Ethereum afterInit 10 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project that implements afterInitialize as a no-op and exposes an initializePools() function that calls an external liquidity bootstrapper and records the initial tick and poolInitialized flag. Ethereum afterInit 10 3mo SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain project that only implements afterInitialize to support pool setup. It stores the initial tick and a poolInitialized flag when called via initializePools(), which delegates to an external liquidity bootstrapper. No swap-side logic is present. Ethereum afterInit 10 3mo SaturnOmnichainV4HookHook with only afterInitialize permission. Exposes an initializePools() function that delegates to an external LiquidityBootstrapper contract to set up liquidity positions, recording the initial tick and marking the pool as initialized. All swap, liquidity, and donate callbacks are pure no-op stubs. Ethereum afterInit 10 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project with only the afterInitialize flag set. The afterInitialize callback is a pure no-op (returns selector only). Pool initialization is triggered externally via initializePools(), which delegates to a LIQUIDITY_BOOTSTRAPPER contract to bootstrap liquidity and record the initial tick. Ethereum afterInit 10 5mo LivoSwapHookSingleton Uniswap v4 hook for tokens graduated via the Livo launchpad that collects a 0.5% LP fee (split 50/50 between creator and treasury) on all swaps, plus an optional time-limited buy/sell tax configurable per token. Swaps are blocked before token graduation. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 10 7mo TokiHookUniswap v4 custom curve hook implementing Pendle-style fixed-rate yield trading for Principal Tokens. Uses a custom AMM curve with optional ERC4626 rehypothecation to boost LP yields, maintains a TWAP oracle for logarithmic implied rates, and enforces curator-controlled pool lifecycle with pause and maturity expiry. Ethereum afterInitbeforeAddLiqbeforeSwapswapDelta 10 9mo UPeg HookCalls `start()` on a configured token when the first liquidity is added to that token's pool, and updates an internal random seed on each swap involving the configured token. Both actions are no-ops when no token is configured or for pools not involving the token.

Liquidity additions are restricted to the factory contract and removals always revert, locking LP positions permanently. Ethereum beforeAddLiqbeforeRemoveLiqafterSwapafterSwapDelta 9 2mo LaunchHookA token launch hook that seeds a single-range liquidity position and charges a high anti-snipe fee (99%) that linearly decays to 1% over 20 seconds post-launch. Only the hook itself can add/remove liquidity. Buy fees are collected via beforeSwap; sell fees via afterSwap. Fees are split between the token creator and a protocol fee escrow. Ethereum beforeInitbeforeAddLiqbeforeSwapafterSwap+2 9 2mo MixpadHookMixpadHook collects a configurable platform fee on every swap for factory-registered tokens, splitting revenue between the token creator and treasury. It applies anti-snipe surcharges in blocks immediately after launch, a time-decaying deployer dump surcharge, optional buyback-and-burn of the creator's fee share, and optional dividend routing to a yield vault.

Supports optional launch-period fee schedules with linear time-decay from a higher opening rate to a settled base rate. Ethereum beforeInitbeforeSwapafterSwapswapDelta+1 9 3mo BDeFiHookBuilDeFi's swap hook that applies configurable buy/sell taxes on each trade, routes proceeds to fee distributors, fulfills queued token orders at TWAP price against collected fees, and records truncated geo-oracle observations. Trading is gated on a per-token fully-initialized flag set by the LP manager. Ethereum beforeInitafterInitbeforeAddLiqbeforeRemoveLiq+4 9 3mo SimHookMVPA dynamic-fee hook that sets LP fees based on simulated price impact and a time-decaying cumulative price imbalance score. Includes an owner-configurable JIT liquidity lock that prevents LPs from removing liquidity within a configurable block window after adding it.

Operates 300-block "heist" windows where buyers earn $LOOT rewards based on buy volume and entry timing, with a probabilistic bust mechanic driven by a global heat accumulator and a swap coherence metric. Ethereum beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+2 9 6mo LimitOrderHookA deployment of OpenZeppelin's LimitOrderHook — a Uniswap v4 hook implementing single-tick limit orders. Users place orders by providing concentrated liquidity at a specific tick; when the pool price crosses that tick, the position is automatically filled and can be withdrawn at any time. Original implementation by OpenZeppelin (github.com/OpenZeppelin/uniswap-hooks). Deployed to Ethereum mainnet to make this functionality publicly accessible.

Fees accumulate per-maker and can be withdrawn via harvest(). Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 8 2mo GweiFeeHookThe single Uniswap v4 hook used by all gwei.fun launchpad pools. In `beforeSwap`, it deducts a configurable fee (platform fee plus optional per-pool creator tax with separate buy/sell rates and a linearly-decaying anti-snipe tax) from the specified currency via BeforeSwapDelta, routing proceeds to the creator's fee recipient and a GWEI buyback vault as ERC-6909 claims.

Satellite pools (ORBIT/quote) use fully custom accounting: buys fill from a hook-held ORBIT reserve, sells draw from banked quote inventory, both priced via Core TWAP × external oracle with a spread earmarked for token burns. The Core pool (ORBIT/WETH) is passthrough-guarded by a TWAP deviation band and per-block notional cap. Ethereum beforeInitafterInitbeforeSwapafterSwap+1 8 4mo Ring FewV2 Aggregator HookOwnerless router-compatible Uniswap v4 hook that exposes Ring FewV2 AMM liquidity through v4 swaps. The hook uses empty hookData, registers aggregator pools, exposes quote and pseudoTotalValueLocked for routing discovery, and has no hook owner, pause, upgrade path, or route-control admin.

Ethereum afterInitbeforeSwapafterSwapswapDelta+1 8 5mo OneTimeLaunchHookTemplateEnforces one-time pool initialization and one-time liquidity addition per token (currency1). In afterSwap, when activated, selectively reverts token-sell swaps (zeroForOne=false) for addresses not on an owner-managed allowlist, while anyone can publicly call bigInt() to enable this restriction. Ethereum beforeInitbeforeAddLiqafterSwap 8 6mo GeodeHookGeodeHook implements a permanent bonding curve venue on Uniswap v4. Direct swaps execute instantly against a constant-product curve via beforeSwap (0.3% fee split three ways), while gasless EIP-712-signed intents are settled in MEV-protected batches at a uniform clearing price (0.1% fee). The curve is the permanent market maker with no graduation or migration. Ethereum beforeSwapswapDelta 8 6mo OneTimeLaunchHookTemplateA launch hook that restricts pool initialization and initial liquidity addition to once per token. In afterSwap, it tracks buy-direction swap recipients and can revert sell-direction swaps for addresses not on a deployer-managed allowlist. Makes non-standard calls (msgSender, msgTarget, msgData) on the token contract that will revert on standard ERC-20 tokens. Ethereum beforeInitbeforeAddLiqafterSwap 8 6mo NoncePoolHookV1A launchpad hook for nonce.fun pools that restricts pool initialization and liquidity provision to a designated launchpad contract. It enforces a fixed opening price, tick range, and fee, allows only one initial liquidity mint per token, locks principal removal, and permanently disables donations. Ethereum beforeInitbeforeAddLiqbeforeRemoveLiqbeforeDonate 8 6mo TokenpadHookA Uniswap v4 hook that collects a 1.25% fee on ETH-in buys (via beforeSwap delta) and ETH-out sells (via afterSwap delta) for registered token pools, forwarding collected ETH to each token's LaunchToken contract for reward distribution, with buffering and rescue mechanisms for failed forwards. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 8 7mo EMADynamicFeeHookEMA-based dynamic fee hook for Uniswap V4. Calculates swap fees using Exponential Moving Average of price, with 30-step fee schedule (0.01%-3.00%) and 300-block anti-JIT protection via tx.origin. No owner, no admin functions, fully immutable.
