Uniswap is the world's leading decentralised exchange (DEX), built on Ethereum. It pioneered the Automated Market Maker (AMM) model, replacing order books with liquidity pools. Anyone can provide liquidity and earn fees, or swap any ERC-20 token without creating an account.
Wrapped Bitcoin (WBTC) is an ERC-20 token on Ethereum representing Bitcoin at a 1:1 ratio. Each WBTC is backed by real Bitcoin held in custody by BitGo. It enables Bitcoin holders to participate in Ethereum's DeFi ecosystem without selling their BTC.
MetaMask is the world's most popular Ethereum wallet, available as a browser extension and mobile app. It allows users to interact with decentralised applications directly from their browser, store Ethereum and ERC-20 tokens, and sign transactions. With over 30 million monthly active users, it is the primary gateway to Web3.
