Hooks allow developers to inject custom logic at key points of a pool’s lifecycle—before swaps, after swaps, during liquidity changes, or fee collection. This enables advanced features like dynamic fees, MEV-resistant swaps, on-chain limit orders, KYC-enabled pools, and custom oracle logic, all without deploying entirely new AMMs. Hooks turn Uniswap into a modular liquidity layer, not just a DEX.
