About Uniswap
Uniswap is the largest decentralized exchange (DEX) by trading volume, built on Ethereum and operating across multiple EVM-compatible chains including Arbitrum, Optimism, Polygon, and Base. It pioneered the automated market maker (AMM) model in 2018 and has processed trillions of dollars in cumulative trading volume. Users trade directly from their own wallets with no account or KYC required. Uniswap v3 introduced concentrated liquidity, allowing liquidity providers to earn higher fees. In 2024 the Uniswap Foundation received a Wells Notice from the SEC, though no enforcement action followed.
