Uniswap V4 is the newest evolution of the Uniswap decentralized exchange protocol, designed to offer advanced customization, improved capital efficiency, and a more flexible AMM architecture. It builds on prior versions while enabling developers to create custom pool logic through a powerful new feature called “hooks.”
Uniswap V4 uses a single, shared liquidity pool architecture where all pools are managed under one contract. Hooks allow developers to add custom behaviors—such as dynamic fees, on-chain limit orders, or other automated strategies—while keeping swaps efficient and gas-optimized.
