Uniswap is one of the largest decentralized exchanges that allows anyone to trade crypto assets and provide liquidity to earn trading fees. Uniswap v4 is the latest version of the protocol, introducing customizable hooks, native ETH support, and dynamic fees. It retains the capital efficiency of v3 while enabling gas savings and greater flexibility through a new singleton architecture.
Uniswap V4 is the latest version of the leading decentralized exchange, re-architected to enable deep customization through a new primitive called hooks. These hooks are smart contracts that execute at defined points in the lifecycle of a liquidity pool—before and after swaps, mints, and burns—allowing developers to build new behaviors directly into pools. Combined with a new singleton design that consolidates all pools into one contract to reduce gas costs, and native support for flash accounting and ERC-1155 tokens, V4 redefines what’s possible within a DEX.
Like previous versions, Uniswap V4 does not charge protocol fees by default, but the Uniswap governance community can vote to enable a fee switch that diverts a portion of swap fees to the DAO treasury. Individual pools can also implement their own dynamic fee models via hooks, potentially monetizing specific strategies or behaviors. The protocol benefits indirectly from increased usage and integrations, which contribute to the overall value of the UNI token and ecosystem.
The basic mechanics for earning haven’t changed from V3: liquidity providers (LPs) supply tokens to a pool and earn fees from trades that use that liquidity. In V4, LPs can choose to participate in pools with custom behaviors—like dynamic fees or time-weighted average market makers (TWAMMs)—which may generate differentiated yield. Advanced users could also deploy their own hooks to extract value through bespoke market strategies or composable DeFi primitives.
