MetaMask, built by Consensys, is the most widely used self-custody wallet for Ethereum and EVM-compatible chains. Available as a browser extension and mobile app, it is the default gateway to DeFi, NFTs and dapps — you control your keys, so it is a wallet rather than an exchange (though it offers in-app swaps and buy).
