MetaMask is a browser extension and mobile application that allows users to interact with Ethereum-based decentralized applications (dApps) and manage their Ethereum wallets. It acts as a digital wallet that securely stores a user's private keys and enables them to interact with the Ethereum blockchain.
With MetaMask, users can create and manage multiple Ethereum wallets, send and receive Ethereum and other tokens, and interact with dApps that are built on the Ethereum network. The extension also provides a built-in Ethereum blockchain explorer, which allows users to view transaction history and track the progress of their transactions.
MetaMask is available as a browser extension for Google Chrome, Firefox, Brave, and Microsoft Edge, as well as a mobile app for both iOS and Android. It has become a popular tool in the decentralized finance (DeFi) space, as it provides users with a simple and secure way to access and use Ethereum-based dApps and protocols.
