Uniswap is a decentralized exchange (DEX) protocol that enables permissionless token swaps and liquidity provision across multiple blockchain networks. Built on Ethereum and expanded to Layer 2s like Arbitrum and Base, Uniswap allows users to trade directly from their wallets without intermediaries. Powered by automated market maker (AMM) smart contracts, it provides deep on-chain liquidity and transparent settlement. With support for multiple pool versions (v2, v3, v4), Uniswap serves as foundational infrastructure for DeFi, enabling trading, liquidity mining, and composable integrations across the Web3 ecosystem.
