15mo TokenFabA token launch platform hook that operates bonding curves for newly deployed ERC-20 tokens. When a token's bonding curve supply is exhausted, liquidity is automatically migrated to a standard AMM pool. Charges a 5% fee on every swap (1% platform, 1% creator, 3% reward pool) taken via afterSwapReturnsDelta. External liquidity additions, removals, and pool initialization are all blocked. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 2 15mo TokenFabToken launch factory hook that manages a bonding curve phase for newly deployed ERC-20 tokens; when the bonding curve supply is exhausted, it automatically migrates liquidity to a wider AMM pool and collects a 5% swap fee split among the creator, platform, and a reward pool. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 2 15mo TokenFabA token launchpad hook implementing a bonding curve that blocks external liquidity management and collects a 5% swap fee split among platform, creator, and a reward pool. When the bonding curve supply cap is reached, the hook automatically removes bonding curve liquidity and migrates it to a new AMM pool. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 2 15mo TokenFabA token launchpad hook that runs a bonding curve for newly launched ERC-20 tokens, blocking external liquidity additions and managing all liquidity internally. When the bonding curve supply cap is reached, liquidity migrates to a full-range AMM pool. A 5% swap fee is collected via afterSwapReturnsDelta, split between the platform (1%), creator (1%), and a reward pool (3%). Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 2 15mo TokenFabA token launchpad hook that manages a bonding curve phase for newly launched ERC-20 tokens. Blocks external liquidity and pool initialization; automatically transitions to a Uniswap v4 AMM pool when the bonding curve supply cap is reached. Takes a 5% swap fee on each trade, split among creator, platform, and a reward pool via afterSwapReturnsDelta. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 2 15mo TokenFabA token launch hook implementing a bonding curve mechanism. Manages liquidity for newly launched tokens, automatically migrating liquidity to a full-range AMM pool when the bonding curve supply is exhausted. Applies a 5% fee on swaps split between platform, creator, and reward pool recipients. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 2 15mo TokenFabTokenFab is a bonding curve launchpad hook that manages token launches through a bonding curve phase, graduating to a standard AMM pool upon reaching the supply cap. It blocks external liquidity modifications, charges a 5% swap fee (split among creator, platform, and reward pool), and handles pool initialization and liquidity settlement internally. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 2 15mo TokenFabA token launch hook implementing a bonding curve that sells newly deployed ERC20 tokens against a configurable base token. When the bonding curve supply is exhausted, it automatically migrates liquidity to a standard AMM pool. Takes a 5% swap fee on base token output, split among platform, creator, and reward pool recipients. Base beforeInitbeforeAddLiqbeforeRemoveLiqafterSwap+1 2 15mo TokenFabA bonding-curve token launchpad hook that initializes permissioned pools for newly created ERC-20 tokens, tracks sold supply against a configurable cap, collects a 5% swap fee split among platform, creator, and a reward pool via afterSwapReturnsDelta, and automatically migrates liquidity to a separate AMM pool when the bonding curve supply cap is reached.

Fees are configurable per pool or via a default rate, controlled by an admin role, and accumulated in the contract for withdrawal to a designated fee recipient. Base beforeSwapafterSwapswapDeltaafterSwapDelta 2 16mo ClankerHookV2A dynamic fee hook that adjusts LP fees based on swap size (0.5%–2% base, up to 4% for sells) and direction, charging double fees for sells (capped at 4%). An owner can activate per-pool emergency mode to enforce the maximum 4% fee. Tracks cumulative volume and swap counts per pool.
