54d CrossrateTaxHookCharges a per-swap tax (3–10% in BPS) on swaps involving the pool's registered quote currency, accruing fees as pool manager claim tokens split between the coin creator and a platform wallet. Anyone can call `distribute` to redeem accrued fees, optionally routing payouts through USDG into native ETH via two hookless pool swaps.

This ETH variant additionally supports native ETH as currency0. Robinhood beforeInitbeforeSwap 10 2mo DualPoolHookJIT liquidity hook that deploys concentrated LP positions across multiple configurable tick ranges (buckets) before each swap and removes them after, using ERC-4626 vault rehypothecation to earn yield on idle capital between swaps. Pool fee is static (set at deploy time); swaps can be paused per-pool by the owner.

Charges a decaying anti-dump sell tax (linear decay over a configurable block window) plus configurable hook and creator buy/sell taxes on registered token swaps. All collected fees are routed to token creators via a claimable balance mapping. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 10 2mo ERC1967Proxy HookAn upgradeable ERC1967 proxy contract that delegates all calls to an implementation address. The hook implements beforeSwap, afterSwap, beforeAddLiquidity, and beforeInitialize, with both beforeSwapReturnsDelta and afterSwapReturnsDelta enabled, indicating it modifies swap deltas. The actual hook logic resides in the unresolved implementation contract. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 10 2mo Frontier FactoryHookSingleton hook governing graduated BCToken pools; blocks swaps until the coin is graduated (`isLPd`), then charges time-decayed volatility-based fees split between LP positions (via dynamic LP fee override) and protocol (via hook delta). The non-LP share is distributed to the protocol treasury, staking vault, and fee recipient via a two-level waterfall. Robinhood beforeInitafterInitbeforeSwapafterSwap+2 10 2mo QuotronFloorHookFee engine for QUOTRON floor pools that overrides LP fees to zero and charges a tiered fee on the stock side via return deltas. During a 6-hour launch window, whitelisted swappers pay 3%; holders of the 100 FCFS reduced-fee spots pay 10%; all others pay 40%. After the window, everyone pays 3%. Each fee is split four ways: ~2/3 to a reflections engine, ~1/6 to a STONKBROKER buy-and-burn pot, ~1/6 to an LP-reinvest pot, and ~5% to a creator address paid directly per swap. Robinhood beforeInitafterInitbeforeSwapafterSwap+2 10 2mo MixpadHookUniswap v4 hook for the Mixpad launchpad that collects platform swap fees on every trade and splits them between the token creator and treasury. Applies a decaying anti-snipe surcharge on early buys and a time-limited surcharge on deployer sells, and routes a configurable share of creator fees into automatic buyback-and-burn of the launched token.

During a brief 4-second anti-snipe window after launch, non-whitelisted traders pay a flat 70% tax instead of the configured rate. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 10 3mo LaunchFeeHookAnti-snipe launch fee hook that overrides the LP fee to 50% for the first 4 minutes after pool initialization, then permanently drops to 3.5%. The fee is applied via dynamic fee override in beforeSwap with no admin controls or setter functions. Robinhood afterInitbeforeSwap 10 3mo 0xcdd5…c088Runs code on every swap · Can take tokens from swaps Robinhood beforeSwapswapDelta 10 3mo LaunchFeeHookApplies a time-based anti-snipe fee to pools: 50% flat fee for the first 4 minutes after initialization, then a permanent 3.5% LP fee floor. Fees are immutable — no admin controls or setters exist.

Also maintains a truncated geometric oracle for pool observations. Robinhood beforeInitafterInitbeforeAddLiqbeforeRemoveLiq+4 10 3mo SaturnOmnichainV4HookA minimal hook for the Saturn Omnichain project that records pool initialization state via an external liquidity bootstrapper.

Robinhood afterInit 10 3mo SaturnOmnichainV4HookMinimal Uniswap v4 hook for the Saturn Omnichain project with only the afterInitialize permission set. The afterInitialize callback is a no-op. Provides an initializePools() function that calls an external LIQUIDITY_BOOTSTRAPPER contract to bootstrap initial liquidity positions and record the initial tick. Robinhood afterInit 10 3mo SaturnOmnichainV4HookUniswap v4 hook for the Saturn Omnichain protocol. Only afterInitialize is enabled (as a no-op selector return).

Robinhood afterInit 10 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project that records pool initialization state.

Robinhood afterInit 10 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project that uses only the afterInitialize permission (as a no-op selector return) to satisfy hook address validation. Stores pool configuration constants and an initial tick, delegating liquidity bootstrapping to an external ISaturnOmnichainLiquidityBootstrapper contract. Robinhood afterInit 10 3mo SaturnOmnichainV4HookA minimal hook with only the afterInitialize permission bit set; the afterInitialize callback is a no-op stub. The contract also exposes an initializePools() function that calls an external ISaturnOmnichainLiquidityBootstrapper to bootstrap liquidity and records the resulting tick. The hook does not affect swap or liquidity-modification execution in any way. Robinhood afterInit 10 3mo SaturnOmnichainV4HookA Uniswap v4 hook for the Saturn Omnichain project that records the initial tick after pool initialization and delegates liquidity bootstrapping to an external LiquidityBootstrapper contract.
