2mo CreatorFeeAntiSnipeHookA launchpad hook that enforces a time-based per-buy WETH cap during a 3-phase launch window (flat cap → linear ramp → uncapped) to deter sniping, and takes a standardized creator/protocol fee split from swap outputs via afterSwap with afterSwapReturnsDelta.

Fees accrue as ERC-6909 claims to the contract and can be forwarded to a treasury address, which is configurable by the owner subject to a 3-day timelock.

Charges a dynamic ETH fee (1%–6.6%) on exact-input swaps: buys are charged on input via beforeSwapReturnsDelta, sells are charged on output via afterSwapReturnsDelta. The fee rate floats with recent tick movement and is sent directly to a per-pool recipient address registered by the factory.

Also locks registered pools against liquidity removal until unlocked. Robinhood beforeRemoveLiqbeforeSwapafterSwapswapDelta+1 2 2mo MoonsendFeeHook_RHA per-pool dynamic LP fee hook for Uniswap v4 that sets configurable fee tiers at pool initialization via updateDynamicLPFee and applies a time-decaying anti-snipe fee surcharge on buys during an optional launch window. Robinhood beforeInitafterInitbeforeSwap 2 2mo YardkeepersFeeHookA Uniswap v4 hook that charges a volatility-based ETH fee on every swap for ETH/token pools. Buy fees are taken from ETH input in beforeSwap; sell fees from ETH output in afterSwap. The fee rate scales dynamically between a configured base and max (1%–7%) based on the tick movement of the previous swap, with fees sent immediately to a per-pool fee recipient.

The beforeInitialize callback verifies that one pool currency is a designated payment token and the other has been approved by a graduation registry, reverting otherwise. Robinhood beforeInit 2 2mo PackrFeeHookA volatility-based ETH fee hook for Uniswap v4 pools, charging fees between 1% and 5.12% based on the previous swap's tick movement. Buy fees are deducted from ETH input in beforeSwap; sell fees from ETH output in afterSwap. Only exact-input swaps are supported — exact-output swaps revert.
