2mo FlashHookFLASH v2 protocol hook for WETH-rooted token ecosystems. Routes buys through an OTC order book and AMM aggregator, charges dynamic sell taxes (including price-impact taxes), and distributes proceeds to stakers, pool creators, and protocol treasury. Requires governance to activate a directional protocol fee before any swaps are permitted. Base beforeInitbeforeSwapafterSwapswapDelta+1 26 2mo AdvancedFeeHookV3A token launchpad fee hook for the BaseStonk platform that collects configurable swap taxes in afterSwap, distributing proceeds among a platform treasury, creator payees, a buyback-and-burn mechanism, and optional single-sided liquidity re-injection. Pool initialization is restricted to a privileged launcher address. Base beforeInitafterSwapafterSwapDelta 26 5mo GitlawnchHookSkims a flat 1% fee on exact-input swaps, taking the fee directly into a Locker contract that splits it 80% to the token creator and 20% to the platform. Pools are created with LP fee 0, making this the sole trading fee mechanism. Base afterInitbeforeSwapswapDelta 26 11mo ZoraV4CoinHookUniswap v4 hook for Zora Coins that collects LP fees from multiple positions on every swap, converts them to a backing currency via multi-hop swaps, and distributes rewards to creators, referrers, and the protocol. Supports limit order filling and liquidity migration to new hook implementations. Base afterInitbeforeSwapafterSwap 26 14mo BoardHookA Uniswap v4 hook implementing a token launch platform with a fair launch mechanism that fills purchases from a dedicated position, enforces time-gated access control (pre-launch block), optional Merkle-proof whitelisting, and distributes swap fees across protocol, creator, inspired, and referral recipients.
