Fee rises with recent price movement and decays back to a per-pool base rate, hard-capped at 10%. Config is per-pool, frozen at initialization; no owner or admin functions. Robinhood afterInitbeforeSwap 9 2mo PopHookSingleton Uniswap v4 hook for graduated $POP meme token pools. Takes a combined hook fee and creator fee from each swap's unspecified currency via afterSwapReturnsDelta. Launch-token fees are batched and converted to the quote token via an internal pool swap at sweep time, then split among protocol, creator, and a cashback mode (QuoteBurn burns to dead address, HolderRewards distributes to token holders). Curve-phase pools also apply a decaying snipe tax on early buys. Robinhood beforeInitafterSwapafterSwapDelta 9 2mo LaunchTaxHookCharges a fixed 1% tax on every swap in strategy-created launchpad pools, denominated in the pool's quote token and split 50/50 between the launchpad deployer and the pool's token creator. Tax is applied via BeforeSwap and AfterSwap return deltas depending on whether the quote is the specified or unspecified currency.

Uses beforeInitialize to revert any external pool initialization attempt, ensuring only the launchpad itself can create pools for launched tokens. Robinhood beforeInit 9 2mo GazzFeeHookCharges a flat 2% ETH-side fee (plus an optional per-coin community fee up to 2%) on every swap in gazz.fun V4 pools, forwarding proceeds to a GazzFeeSplitter. Fee is always taken in native ETH regardless of swap direction. Rejects non-native-ETH pools at initialization. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 9 2mo RichFeeHookCharges a volatility-based ETH fee on buys (beforeSwap delta) and sells (afterSwap delta), scaling the rate between a configurable base and max (both in the 1–5% range) based on the previous swap's tick movement. Fees are sent immediately to a per-pool recipient address set at registration. Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 9 2mo FriarA volatility-responsive dynamic LP fee hook that adjusts swap fees using the Liquidity Book volatility-accumulator mechanism, surging fees with recent price movement and decaying back after configured windows. All parameters are immutable with no owner or upgrade mechanism. Robinhood afterInitbeforeSwap 9 2mo LaunchpadHookA permissionless launchpad game hook that seeds ETH-paired token pools and tracks swaps in afterSwap to run a timed competition: sufficiently large buys defend an escalating floor price, update the leader, and accrue LP fees to a pot awarded to the last qualifying buyer when the idle timer expires. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+1 9 2mo GataraEthHookA Uniswap v4 hook for token launches with native ETH as the quote currency. Charges directional fees (buy/sell) split between the pool creator, protocol treasury, and a time-decaying cocoon surcharge, using beforeSwap/afterSwap delta returns. Blocks buys in the exact launch-second as an anti-snipe guard. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 9 3mo ERC1967ProxyAn upgradeable ERC1967 proxy hook with beforeSwap, afterSwap, beforeInitialize, afterInitialize, beforeAddLiquidity, and afterSwapReturnsDelta permissions. The implementation contract source is not verified, so full behavioral analysis is not possible.

Pool fees are static (set at creation via PoolKey.fee and explicitly rejects dynamic-fee pools); hookData is ignored on swaps. Robinhood beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+1 9 3mo HoodlumPadHookShared Uniswap v4 hook for HoodlumPad V2 memecoin launches. Skims a fixed 1% fee from memecoin swaps (split 50/50 between creator and protocol treasury) as ERC-6909 claim tokens, maintains a self-hosted 200-slot TWAP oracle, and provides a batched fee-conversion mechanism to swap accrued memecoin fees into the quote asset. Robinhood beforeInitafterInitbeforeAddLiqbeforeSwap+3 9 3mo PmavHookQuotedBonding curve launchpad hook for memecoins with block+1 anti-snipe protection, a permanent 2% wallet cap with auto-refund, a decaying anti-snipe fee premium, and automatic graduation to a standard 1% dynamic-fee pool once the curve fills. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 9 3mo PmavHookQuotedBonding-curve launch hook for pmav.fun's ERC-20 quoted lane. Runs a constant-product curve with a 1% base fee (70/30 creator/platform), block+1 anti-snipe, decaying early-buy premium, permanent 2% wallet cap with auto-refund waterfall, and in-place graduation that reshapes to a full-range Uniswap v4 pool and sets a dynamic LP fee. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 9 3mo RobinoHookObservation hook for Robino graduated pools that emits events on pool initialization, liquidity changes, and swaps. Pool initialization is gated to tokens registered in the Robino factory; afterSwap only records swap data via events without modifying execution. Robinhood afterInitafterAddLiqafterRemoveLiqafterSwap 9 3mo FoundryHookV4Shared fee hook for the Foundry launchpad on Robinhood Chain, enforcing a dynamic ETH-denominated trade fee (1.00–1.25%, tiered by pre-trade market cap) split between creator and protocol, with anti-snipe buy caps during the first 3 blocks and a block on outside liquidity providers pre-graduation. Robinhood beforeAddLiqbeforeSwapafterSwapswapDelta+1 9 3mo RobinShareHookA shared hook for RobinShare native ETH/TOKEN pools that takes an immutable ETH-denominated fee (1–5%) on every swap and distributes it instantly per-swap to a platform wallet, a buyback reserve, and configurable recipients. Supports agent-triggered buyback-and-burn via internal fee-exempt swaps.

Fees in the paired asset are split among the protocol (30%), creator, and a buyback bucket; fees in the launch token are held and converted separately by a keeper. All liquidity is owned by the hook and locked permanently. Robinhood beforeInitafterSwapafterSwapDelta 8
