In this blog post, we’ll break down what the MetaMask browser extension is, how it works, and how you can get started safely and confidently.

• Interact with the Ethereum blockchain and compatible networks (like Polygon, BNB Chain, etc.)
• Buy, send, and swap crypto directly from your wallet

MetaMask is available as an extension for Chrome, Firefox, Edge, and Brave browsers, as well as a mobile app for iOS and Android.
