Uniswap is a decentralized exchange, commonly called a DEX, developed on the Ethereum blockchain. Traders use Uniswap to instantly swap ERC-20 tokens without requiring a liquid market of buyers and sellers or intermediaries. The network prioritizes censorship resistance, security, and self-custody without needing third-party intermediaries. Contrary to a centralized exchange which processes trade orders internally via an Order Book, a decentralized exchange operates an Automated Market Maker (AMM) which functions as a constant, permissionless liquidity pool that traders can interact with directly on-chain. UNI is the native token of the Uniswap protocol, and is available to be traded in a variety of markets on OKX. UNI is required to vote on proposals that govern the development of the Uniswap platform. You can also use UNI to create liquidity pairs and earn crypto rewards.
