2mo EggsFeeHookA Uniswap v4 hook for Eggs Launchpad pools that charges a flat fee (0.1%–5.2%) on ETH-denominated swaps: taken from the input on buys (beforeSwap) and from the output on sells (afterSwap), forwarded to a per-pool fee vault. Only exact-input swaps are permitted; exact-output swaps revert. Pool registration is restricted to a single authorized factory address. Robinhood beforeInitbeforeSwapafterSwapswapDelta+1 35 2mo ERC1967Proxy HookA Uniswap v4 hook deployed as an ERC1967 upgradeable proxy. The implementation contract is not verified, so the full hook logic cannot be analyzed. The address bitmask indicates beforeSwap with delta return, beforeInitialize, and beforeAddLiquidity permissions. Robinhood beforeInitbeforeAddLiqbeforeSwapswapDelta 35 3mo LaunchpadHookCollects a configurable percentage fee on every swap for registered launchpad token pools, splitting proceeds between the token creator and platform treasury, with optional referral rewards distributed via an external registry.

Enforces permissioned pool initialization via a launcher, optional liquidity exclusivity during the bootstrap phase, and optional buy-side gating that requires buyers to be pre-authorized by an on-chain gate authorization contract. Robinhood beforeInitbeforeAddLiqbeforeSwap 35 3mo FriarA dynamic LP fee hook that tracks per-pool swap volatility using a volatility accumulator with configurable filter and decay periods. On each swap, the accumulator updates based on tick movement and computes a fee that surges with volatility and decays afterward, hard-capped at a maximum, returned as a beforeSwap LP fee override with zero delta. Robinhood afterInitbeforeSwap 35 3mo SniperAuctionAnti-snipe fee hook that charges a linearly decaying buy-side fee (configurable up to 99%) during a short launch window (5–30s), then zero fee afterwards. Fee proceeds are taken directly from WETH input via BeforeSwapDelta and distributed 70% to the token creator / 30% to the platform once a 0.01 WETH threshold accumulates. Robinhood beforeInitafterInitbeforeAddLiqbeforeSwap+3 35 13mo TokenFabA bonding curve token launchpad hook that manages token launches, collects configurable platform and creator fees on swaps, and automatically migrates fully-bonded tokens from the bonding curve pool to a standard AMM pool upon reaching the target supply. Base beforeInitbeforeAddLiqbeforeRemoveLiqbeforeSwap+3 35 21mo BunniHookA Uniswap v4 hook that fully handles swap execution via custom BunniSwapMath, computing output amounts and fees directly rather than delegating to the pool manager. Features a TWAP oracle, dynamic surge-based fees, am-AMM manager fee support, and a hooklet plugin system for extensible fee and price overrides.

The `beforeSwap` handler intercepts trades on YES/USDC and NO/USDC pools: for buy orders it mints equal YES+NO tokens from USDC, performs an internal swap on the YES/NO pool to consolidate into the desired token, and returns the delta to settle the trade entirely within the hook.

Fees are minted as ERC-6909 claims to support single-sided launch pools and flushed on subsequent swaps. Includes launch-block locking and per-origin anti-snipe buy caps in USD for the first few blocks after pool deployment.

Robinhood beforeSwapafterSwapswapDeltaafterSwapDelta 33 10mo AI Protocol Swap Fee Hook v1 (Base)A Uniswap v4 hook that charges a configurable fee on swaps involving a designated fee token. Fees are collected in beforeSwap and afterSwap based on whether the operation is a buy or sell and whether the swap is exact-in or exact-out, then forwarded to a configured fee recipient contract.

Captures all trading fees in WETH via swap deltas with a three-phase fee model: exponentially decaying 90%→3% during the guard phase (~5s), then flat 1% through curve and post-graduation. Enforces per-wallet and per-block buy caps during the first ~10s. Graduates the pool automatically when cumulative WETH raised crosses a configured threshold. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 32 3mo LaunchHookThree-phase token launchpad hook: a 50-block guard phase with exponentially decaying fees (90%→3%), a flat 1% curve phase until a cumulative quote graduation threshold is met, then a permanent 1% graduated phase. The hook captures 100% of trading fees via before/afterSwap deltas and routes them through a FeeRouter. Per-wallet and per-block buy caps are enforced during the first 100 L2 blocks to limit sniping. Robinhood beforeInitbeforeAddLiqbeforeSwapafterSwap+2 32 11mo BCHookCollects a static 10% fee on all swaps in ETH/BC token pools, converting token fees to ETH via an internal nested swap and distributing 90% to a league pool and 10% to a fee address. Liquidity additions are restricted to the BCFactory, and exact-output swaps are blocked. Ethereum afterAddLiqafterSwapafterSwapDelta 32 12mo UniswapCupHookUniswap v4 hook for the UniswapCup protocol that restricts pools to exact-input swaps only and collects a percentage fee from each swap's output. If the output token is non-native, the fee is converted back to ETH via a nested pool swap inside afterSwap. Collected ETH is forwarded to the factory owner, and transfer restrictions on UniswapCupTeamToken are updated after each swap.
