Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 16 3mo PonsV2MemeHookSingleton post-graduation hook for Pons V2 meme pools that charges a configurable fee on each swap via afterSwap (using the delta return mechanism), converts any memecoin-denominated fees back to the pool's quote currency through internal swaps, then splits the proceeds among protocol, creator, and buyback-and-lock buckets. Robinhood beforeInitafterSwapafterSwapDelta 16 3mo EthCreatorFeeHookV3Charges configurable directional buy/sell fees on native ETH/token pools, splitting proceeds between a creator reward vault (authenticated via a fee-split vault factory) and a fixed launcher fee recipient. Fees are applied via BeforeSwapDelta for native-specified swaps and via afterSwap return delta for token-specified swaps. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 16 3mo MoonsendFeeHook_RHGates pool initialization to factory-registered pools and sets a dynamic LP fee once via `poolManager.updateDynamicLPFee()` in `afterInitialize`. Has no swap-time callbacks; all swap behavior is standard Uniswap v4. Robinhood beforeInitafterInit 16 3mo SaturnOmnichainV4HookA Saturn Omnichain project hook that registers `afterInitialize` as a no-op callback. Initial liquidity setup is performed via a separate `initializePools()` function that invokes an `ISaturnOmnichainLiquidityBootstrapper` contract and records the initial tick. Has no swap-time logic — swaps execute identically to a standard Uniswap v4 pool. Robinhood afterInit 16 3mo SaturnOmnichainV4HookA hook for the Saturn Omnichain project with only afterInitialize permission. The afterInitialize callback is a no-op; liquidity is bootstrapped separately via initializePools(), which delegates to an ISaturnOmnichainLiquidityBootstrapper contract and records the initial tick.

Supports a module-based programmability system that receives trade callbacks for composable post-swap logic. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 15 2mo 0xc27e…4840Runs code on every swap · Gates who can add liquidity Robinhood beforeAddLiqafterSwap 15 2mo SpotA full-range liquidity hook that applies a dynamic LP fee (base + surge) computed by an external DynamicFeeManager, charges a protocol POL share plus an undisclosed extra 0.10% fee on every swap, reinvests collected fees into a full-range liquidity position, and records truncated geometric mean oracle observations for volatility-adaptive fee tuning. Robinhood afterInitbeforeSwapafterSwapswapDelta+1 15 2mo LaunchHookFee engine for a token launchpad that charges a configurable protocol + creator fee (in the pool's quote token) on every swap via BeforeSwapDelta and afterSwapReturnsDelta. Pools are registered by a factory, liquidity is seeded exactly once and permanently locked, and an optional linearly-decaying anti-snipe fee surge applies in the blocks after launch. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 15 2mo 0x0f91…a0ccRuns code on every swap · Can take tokens from swaps · Runs at pool creation Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 15 2mo ApexHookCollects a configurable flat fee (in basis points) on every swap for factory-registered token pools, routing fees to the token creator's claimable balance. Uses beforeSwap and afterSwap return deltas to extract fees from both exact-input and exact-output swap directions. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 15 2mo PulseHookA fee-collection hook for a token launch platform (Pulse) that charges buy/sell fees and time-decaying anti-snipe fees during early blocks after launch. Fees are taken from the quote currency and routed to token creators' claimable balances. Tokens must be registered via the factory contract before fee logic activates. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 15 2mo BaldPadFunFeeHookVolatility-based ETH fee hook for BaldPadFun launch pools. Charges 1–5% fees in native ETH on exact-input buys (via beforeSwap delta) and sells (via afterSwap delta), with the fee scaling linearly based on the previous swap's tick movement. Fees are sent directly to a per-pool fee recipient on each swap. Exact-output swaps are rejected.

Robinhood afterInit 15 3mo SaturnOmnichainV4HookA minimal hook with only an afterInitialize permission. The afterInitialize callback is a no-op. The contract also exposes an initializePools() function (not a hook callback) that calls a liquidity bootstrapper to record an initial tick in the hook's storage. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain protocol. Implements only `afterInitialize` (a no-op callback that returns the selector). Exposes `initializePools()` which calls an external `ISaturnOmnichainLiquidityBootstrapper` to bootstrap initial liquidity and records the resulting tick. Does not affect swaps in any way. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project that records an initial tick on pool initialization. Exposes an `initializePools()` function that delegates to a liquidity bootstrapper contract to seed initial liquidity and store the starting tick. Robinhood afterInit 15 3mo SaturnOmnichainV4HookA Uniswap v4 hook for Saturn Omnichain that defines pool configuration constants (3000 bps fee, 60 tick spacing) and delegates liquidity bootstrapping to an external ISaturnOmnichainLiquidityBootstrapper contract. The afterInitialize callback is a no-op; all swap-related callbacks are absent or no-ops, so swap behavior is fully vanilla. Robinhood afterInit 15 3mo SaturnOmnichainV4HookUniswap v4 hook for the Saturn Omnichain project.
