TokenFabToken launchpad hook implementing a bonding curve for newly deployed ERC-20 tokens. Blocks external pool initialization and liquidity addition, collects a fixed 1% swap fee split 50/50 between creator and platform via afterSwapReturnsDelta, and automatically migrates liquidity to a full-range AMM pool once the bonding curve supply is exhausted.

OFinHookFee and curve hook for OFin token launches. Each launch's bonding curve is a V4 position in its pool, and only the OFin factory adds liquidity. It takes fees in the quote asset and graduates the pool into locked full-range liquidity when the curve sells out. No hookData, no owner, immutable.
