MetaMask Extension – Browser Wallet for Web3

MetaMask Extension is a popular browser-based cryptocurrency wallet that allows users to manage digital assets and interact with decentralized applications directly from their web browser. It serves as a gateway to the Web3 ecosystem, enabling secure connections to blockchain networks.

Available for Chrome, Firefox, Edge, and Brave browsers, MetaMask Extension provides a simple and powerful interface for accessing decentralized finance, NFT platforms, and blockchain-based services.

What Is MetaMask Extension?

MetaMask Extension is a non-custodial crypto wallet that operates as a browser extension. It allows users to create or import wallets, store private keys locally, and sign blockchain transactions securely.

Because MetaMask is non-custodial, users have full control over their wallets and recovery phrases.

Why Use MetaMask Extension?

How MetaMask Extension Works

MetaMask Extension generates a wallet that is stored locally in your browser. When you visit a Web3-enabled website, MetaMask acts as a bridge, allowing you to connect your wallet and approve transactions.

Security Note: MetaMask never stores your private keys or recovery phrase on its servers. All sensitive data remains encrypted on your device.
