MetaMask is a popular browser extension that serves as a cryptocurrency wallet and a gateway to decentralized applications (dApps) on the Ethereum blockchain. With over a million users, it allows individuals to securely store, manage, and exchange Ethereum and other ERC-20 tokens directly within their web browsers. The extension encrypts users' private keys and provides a user-friendly interface for interacting with decentralized finance (DeFi) platforms, non-fungible tokens (NFTs), and other blockchain-based services. MetaMask also enables users to participate in Ethereum-based crowdfunding events known as Initial Coin Offerings (ICOs) and access decentralized exchanges (DEXs) for trading digital assets. https://sites.google.com/view/metamaskwallettextension/home https://sites.google.com/view/metamaskchrameextension/home
