Reverts if no LP route or sufficient inventory is available; hookData is ignored; an owner can register explicit LP pool mappings.

Each swap atomically mints or redeems vault positions via a primary hook, installs a transaction-scoped concentrated liquidity position sized to match the swap, executes through the pool, then removes it in afterSwap. External liquidity additions are blocked; swaps use a dynamic fee override at a fixed 30 bps protocol charge.

All swaps are fully intercepted via BeforeSwapDelta (no passive liquidity); a fixed 0.30% USDG fee routes to a buyback module. Base beforeInitbeforeAddLiqbeforeSwapswapDelta 6 53d PotatoV4HookA token launch platform hook that manages bonding curve-style launches. Takes a 1% fee on buy swaps via BeforeSwapDelta (burns fee tokens on sells), enforces a 4-second anti-snipe window at launch, caps per-wallet token holdings, and tracks graduation when a quote-token liquidity threshold is reached. Fees are split among creator, protocol, and referrer. Robinhood beforeInitafterInitbeforeAddLiqbeforeRemoveLiq+4 6 53d HoodpadV2MemeHookSingleton Uniswap v4 hook shared by all Hoodpad v2 graduated meme pools. Charges a protocol fee and per-pool creator tax on every swap via afterSwap return delta, accumulates them as pending balances, and allows a trusted sweep operator to convert memecoin-denominated fees to the quote currency via internal swaps and distribute proceeds to the protocol, creator, and a five-year buyback-and-lock vault. Robinhood beforeInitafterSwapafterSwapDelta 6 53d LaunchFeeHookA Uniswap v4 hook that charges a configurable fee (up to 5%) on the quote asset of every swap for launch pools, replacing the LP fee. Supports dual-pool "mirror" swaps that route a portion of each trade through a partner pool to minimize price divergence between paired markets.

For dual-pool tokens (coin + NFT floor token), it mirrors 50% of each trade through the paired collection pool to keep both markets synchronized. Base beforeSwapafterSwapswapDeltaafterSwapDelta 6 54d RdogTaxHookA tax hook for the rdog.fun meme-coin launchpad that deducts a configurable tax from every swap's output in afterSwap. On buys (ETH→token), it burns a percentage of the token output immediately; on sells (token→ETH), it splits the ETH output among a dividend pool, a buyback reserve, and a platform fee recipient.

Captured fees are donated back to the pool LP in afterSwap. Supports progressive liquidity tiers for relaunches; hookData is unused and no custom swap data is required.

Fees are collected via swap deltas and claimable by the creator on-chain, with optional X-linked claims via EIP-712 signatures.

Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 6 2mo DecayFeeHookCharges a linearly decaying swap fee on the unspecified currency (via afterSwapReturnsDelta), from a configurable start rate down to an end rate over a fixed decay window. When the fee is denominated in the launched token, it converts it to stock via a nested pool swap and credits all proceeds to a MultiPool contract as ERC-6909 claims.

Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 6 2mo SimHookDynamic-fee hook that prices each swap using simulated price impact and a time-decaying cumulative price imbalance, with JIT liquidity protection and a governance-configurable protocol fee taken via afterSwap hook delta.

Pools hold no native liquidity; all swaps are fully consumed and settled via ERC-6909 claims inside the PoolManager. Trading is gated by a market clock and Chainlink price freshness checks.

BNB beforeSwapafterSwapswapDeltaafterSwapDelta 6 2mo ApeLaunchHookA launchpad hook that applies a 2% fee on every swap (1.5% to the pool creator, 0.5% to a protocol treasury), splitting fees between exact-input swaps (taxed in beforeSwap) and exact-output swaps (taxed in afterSwap). Liquidity addition is gated via transient-storage authorization, allowing only the launchpad and a designated locker to add liquidity. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 6 2mo DreddHookA fee-collection hook for factory-registered token pools that deducts configurable swap fees via return deltas in beforeSwap and afterSwap, applies an elevated sniper tax to early buyers within a configurable block window after launch, and accumulates fee earnings for token creators to withdraw.
