3mo B20HookA fee-collection hook for the klik.finance B20 launchpad that takes market-cap-tiered ETH fees on exact-input buy swaps, distributing them between a platform treasury and the token creator. Includes a launch-window anti-snipe guard that blocks buys in the deployment block and caps per-origin ETH spend in the first few blocks. Base beforeInitbeforeSwapafterSwapswapDelta+1 371 5mo ThryxAntiSniperHookV5An anti-sniper hook for token launches that applies a time-decaying fee (up to 80% at t=0, decaying over a configurable window to a permanent 1% base) on exact-input swaps, with fees split between pool creators and the protocol. Supports per-pool parameter overrides, a block-multiplier surcharge for rapid sequential swaps, and an optional agent credential bypass via signed hookData. Base beforeSwapafterSwapswapDelta 340 18mo UniswapV4KEMHookA Uniswap v4 hook that enforces signed quotes for exact-input swaps. Each swap requires hookData containing a valid signature from an authorized quoteSigner; if the swap yields more output than the quoted maximum exchange rate allows, the excess is minted as ERC6909 tokens to an admin-controlled recipient. Base beforeSwapafterSwapafterSwapDelta 324 9mo ClankerHookDynamicFeeV2Uniswap v4 hook for Clanker token pools that dynamically adjusts LP fees based on a tick-volatility accumulator model, and takes a protocol fee (20% of the LP fee) on swaps involving the non-Clanker paired token.
