MetaMask is a popular cryptocurrency wallet that allows users to interact with the Ethereum blockchain. It is a browser extension available for Google Chrome, Firefox, Brave, and Edge, as well as a mobile app for iOS and Android devices.
MetaMask is a non-custodial wallet, which means users control their own private keys to access their funds. Private keys are encrypted and stored locally on the user's device for added security. MetaMask also generates seed phrases, which act as a backup to restore accounts if needed.
One of MetaMask’s key features is enabling users to connect to decentralized applications (dApps) on the Ethereum blockchain. For example, users can connect MetaMask to DeFi platforms like Uniswap to trade tokens, lend, borrow and earn interest. MetaMask essentially serves as a bridge between dApps and users’ Ethereum wallets.
Overall, MetaMask provides a secure and decentralized way for users to send, receive, and interact with ERC-20 tokens and Ethereum-based decentralized apps. With an intuitive interface and cross-device functionality, MetaMask has become one of the most popular tool for DeFi and Web3 applications.
