The MetaMask Chrome Extension is a popular browser-based cryptocurrency wallet that allows users to store digital assets, interact with decentralized applications (dApps), and explore the Web3 ecosystem directly from Google Chrome.

🔑 Recovery Phrase (Most Important)

Your 12-word Secret Recovery Phrase is the master key to your wallet.

  • Never share it with anyone

If you lose your recovery phrase, you lose access to your funds permanently.

🛡️ Security Tips

  • Enable hardware wallet integration for extra security

  • Keep your browser updated
  • Beware of phishing pop-ups

MetaMask will never ask for your recovery phrase via email or pop-up messages.

🔄 Restoring MetaMask

If you change devices or uninstall Chrome:

1️⃣ Reinstall the MetaMask extension
2️⃣ Click Import Wallet
