3mo SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain project that records the initial tick after pool initialization via an external liquidity bootstrapper contract. All swap and liquidity callbacks are no-ops; the only active permission is afterInitialize. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project that registers an afterInitialize permission (the callback is a no-op stub). Exposes an external initializePools() function that bootstraps liquidity via an external contract and records the initial tick and pool initialization state. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain protocol with only the afterInitialize flag set. All hook callbacks are pure no-ops. The hook exposes an initializePools() function that calls an external ISaturnOmnichainLiquidityBootstrapper to bootstrap liquidity and records the initial tick. Robinhood afterInit 15 3mo SaturnOmnichainV4HookMinimal omnichain hook for the Saturn protocol with only an afterInitialize permission. The afterInitialize callback is a no-op (pure, returns selector); actual pool initialization is delegated to an external ISaturnOmnichainLiquidityBootstrapper contract via initializePools(). Robinhood afterInit 15 3mo SaturnOmnichainV4HookImplements IHooks with only afterInitialize enabled; the afterInitialize callback is a pure no-op. Provides a separate external initializePools() function that records the initial tick by calling an external liquidity bootstrapper contract (ISaturnOmnichainLiquidityBootstrapper). All other hook callbacks are no-ops. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA hook for the Saturn Omnichain project that records pool initialization state. Only the afterInitialize flag is active, but the callback is a pure no-op; an external initializePools() function delegates liquidity bootstrapping to a separate ISaturnOmnichainLiquidityBootstrapper contract. Swap behavior is entirely unmodified. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA minimal Uniswap v4 hook for the Saturn Omnichain protocol that implements only afterInitialize (as a no-op). Provides an initializePools() function that delegates to an external ISaturnOmnichainLiquidityBootstrapper to seed initial liquidity and record the starting tick. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA minimal Uniswap v4 hook for the Saturn Omnichain token. Declares the afterInitialize permission but performs no logic in any hook callback — all callbacks are pure stubs. Liquidity bootstrapping and initial tick recording are handled via a separate initializePools() function that calls an external LiquidityBootstrapper contract. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA minimal Uniswap v4 hook for the Saturn Omnichain project that records the initial tick after pool initialization via an external liquidity bootstrapper contract. All swap, liquidity, and donate callbacks are no-ops; only afterInitialize is active. Robinhood afterInit 15 3mo SteakHouseV4HookA Uniswap v4 hook for token launches that enforces per-band or time-based configurable LP fees across 8 MCAP bands, with per-band maxWallet and maxTx limits. Features an optional sniper tax (40–80%) for the first 12 seconds post-launch, a 24-second dev-buy window capped at 15% of supply, and an owner-managed volume-bot exemption whitelist that trades with 0% LP fee.

It applies a dynamic LP fee with a time-decaying anti-sniper fee (99% → normal) in the first 3 seconds after launch, and reverts any swap that would push the pool price below its birth price.

The underlying implementation contract (0xCEE1e713Ae68Bf4d1baf4E182b592A92EA444fFC) was not available for source analysis; behavioral properties could not be verified. Robinhood beforeInitafterInitbeforeSwapafterSwap 14 58d SentryStockFeeHookV4A Uniswap v4 hook for tokenized stock pools on Robinhood Chain that charges a time-decaying fee on the stock leg of every swap, splitting proceeds among holder reflections, creator, terminal pot, and growth sink. The pool LP fee is zeroed out; fees are taken entirely via hook deltas. Only the factory's LP vault may add liquidity. Robinhood beforeInitafterInitbeforeAddLiqbeforeSwap+3 14 59d CookHookA bonding-curve token launch hook for Uniswap v4 that manages a main liquidity band, charges protocol and creator swap fees via the afterSwap return delta, and atomically graduates a launch when the target price is reached — burning the main band position, re-pooling the raised base as a permanently locked buy-wall position (Position 3), and optionally initiating a TWAP buy program. Robinhood beforeInitafterInitafterSwapafterSwapDelta 14 2mo NasdankFeeHookPairUniversalA fee hook for coin/pair-token V4 pools (LP fee 0) that takes a configurable fee in the pair token on every swap via BeforeSwapDelta/afterSwapReturnsDelta mechanics. Fees accrue as ERC-6909 claims on the PoolManager, then are split at claim time: the creator leg is paid in the pair token, and the protocol leg is converted to WETH via a frozen V3 route (direct single-hop or 2-hop via USDG with TWAP floors). Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 14 2mo SpotUniswap v4 hook that applies dynamic LP fees (base + surge) computed by a DynamicFeeManager, takes a configurable protocol fee share on swaps and reinvests it via a FullRangeLiquidityManager, and records truncated geometric TWAP observations via TruncGeoOracleMulti.

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.

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.
