Unifi is a crypto trading protocol that offers a variety of cross chain trades, high yield staking pools and other DeFi functionality. You can earn reward tokens by staking several different cryptos to fill the Unifi liquidity pools. Liquidity pools are collections of people's money that make it easier to find a buyer or a seller by always having several kinds of crypto readily available. Contributors to the Unifi pools earn rewards and can access a wide range of Defi utilities to make the most of their investments. By working with several different blockchains and enabling automated swaps across them, Unifi is trying to make trading crypto between chains as smooth as possible.
