What is MetaMask?

MetaMask is a digital wallet and gateway to the Ethereum blockchain. It enables users to store, send, and receive Ether (ETH), as well as manage various ERC-20 and ERC-721 tokens. However, it offers more than just wallet functionality. It acts as a bridge between your browser and the Ethereum network, making it easy to interact with decentralized applications and sign transactions securely.

Key Features of MetaMask:

  1. Wallet Management: MetaMask allows you to create and manage Ethereum wallets. You can import existing wallets or create new ones with a simple seed phrase.

  4. Mobile App: In addition to the browser extension, MetaMask Extension offers a mobile app for both Android and iOS. This extends access to your Ethereum assets and DApps to mobile devices.

  5. DApp Browser: MetaMask includes a built-in DApp browser, allowing you to interact with Ethereum-based applications directly from the extension.
