MetaMask Extension

Secure Ethereum and Web3 wallet for your browser

What is MetaMask Extension?

The MetaMask Extension is a browser-based wallet that allows you to manage Ethereum, ERC-20 tokens, and NFTs directly from Chrome, Firefox, Edge, or Brave.

Your private keys remain local to your browser extension, ensuring security while accessing decentralized networks.
