Uniswap is currently the world's largest and most influential decentralized exchange (DEX) by trading volume, and one of the most important infrastructures in the Ethereum ecosystem. Unlike traditional centralized exchanges such as Binance, Uniswap operates on automated smart contracts, completely eliminating the concepts of "order books" and "centralized matching engines." Through its pioneering automated market maker (AMM) model, it enables permissionless peer-to-pool trading of cryptocurrencies, sparking the explosive growth of decentralized finance (DeFi).
