The MetaMask Extension is a browser-based cryptocurrency wallet that allows users to securely manage digital assets and interact with decentralized applications (dApps) directly from their browser. Available for browsers like Google Chrome, Firefox, Brave, and Edge, MetaMask is a gateway to Web3, providing a seamless interface for Ethereum and other compatible blockchain networks.

Developed by Consensys, MetaMask is trusted by millions of users worldwide and offers both convenience and security for managing crypto assets online.

What Is MetaMask Extension?

MetaMask is a software wallet that integrates directly into your web browser. Unlike exchange wallets, which store your assets online, MetaMask gives you full control of your private keys, keeping them locally encrypted on your device.

With the MetaMask Extension, users can:

• Store, send, and receive Ethereum and ERC-20 tokens
• Connect to decentralized applications (dApps)
• Swap tokens securely
• Manage multiple accounts
• Explore NFT marketplaces and DeFi platforms
