Uniswap (UNI) is a platform on the Ethereum blockchain that lets you trade cryptocurrencies directly without needing a middleman. Instead of traditional order books, it uses a system where users add their tokens to pools and earn fees from trades. The UNI token lets users vote on changes to the platform. Uniswap is known for its innovative features, such as making better use of pooled funds in its V3 version. As a leading and popular platform in the decentralised finance (DeFi) world, Uniswap provides exposure to this rapidly growing space.
