🦊 MetaMask Extension

The MetaMask Extension is a browser-based cryptocurrency wallet that allows users to interact with the Ethereum blockchain and other EVM-compatible networks directly from their browser. It functions as both a secure wallet for digital assets and a gateway to decentralized applications (dApps), making it one of the most widely used Web3 tools today.

Available for Chrome, Firefox, Edge, and Brave browsers, MetaMask enables seamless access to DeFi platforms, NFT marketplaces, blockchain games, and more.

🔐 What Is MetaMask?

MetaMask is a non-custodial wallet, meaning you control your private keys. When you install the extension, it generates a 12-word Secret Recovery Phrase that acts as the master key to your wallet. Only you have access to this phrase.

If you lose it, you lose access to your funds. If someone else gets it, they can control your crypto.

  1. Visit the official MetaMask website:
    👉 https://metamask.io
  2. Click Download
  3. Choose your browser (Chrome, Firefox, Edge, or Brave)
  4. Install from the official browser store
  5. Pin the extension to your toolbar

⚠️ Always verify that you are installing the official version to avoid phishing extensions.
