2mo LaunchHookA token launch hook that locks liquidity to the hook itself and charges time-decaying anti-snipe fees on swaps (starting near 99% and decaying to the configured fee over 20 seconds). Fees are split between a creator fee recipient and a platform escrow. Optional 96-byte hookData enables referral address and trade comment tracking via emitted Trade events. Ethereum beforeInitbeforeAddLiqbeforeSwapafterSwap+2 6,209 6mo FeeHookV3A fee-collection hook for token launch pools that charges ETH-denominated fees on each swap, splitting proceeds among a registered token creator, an optional partner, an optional hot-swappable extension module, and a protocol wallet. Fee rates are determined by a configurable market-cap-tiered table or per-token custom fees with automatic decay. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 5,115 6mo UniversalKlikHookA tiered tax hook for ETH/token pools that takes buy and sell fees scaled by the token's market cap (queried from a factory oracle).

Ethereum beforeInitbeforeSwapafterSwapswapDelta+1 248 6mo FeeHookCollects ETH fees on token swaps, splitting proceeds between the token creator and a protocol wallet. Blocks swaps at launch block unless explicitly permitted by the token factory, and disables fee collection once a pool's market cap exceeds a configurable graduation threshold. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 240 2mo LaunchpadHookA token launchpad hook that implements a constant-product bonding curve priced in IMD tokens. Swaps on launched token pools (ETH/coin) are fully consumed in beforeSwap: the ETH leg routes through a canonical ETH/IMD pool, and the IMD proceeds price the coin against a per-coin virtual reserve curve. Creator fees (ETH) and burn fees (IMD) are applied on each trade. Ethereum beforeInitbeforeAddLiqbeforeSwapswapDelta 211 2mo PositionManagerFlaunch protocol hook managing token launches with scheduled temporal gating, an internal swap pool that pre-fills swaps from fee inventory before Uniswap execution, per-swap fee capture and distribution, optional referral fees via hookData, and a bid wall mechanism for liquidity management.
