Overview
MetaMask Extension acts as a bridge between web browsers and blockchain networks like Ethereum, Arbitrum, or Polygon. As a browser extension, it stores your private keys locally and allows you to sign transactions securely. By using MetaMask, users retain full ownership of their digital assets and can interact safely with thousands of decentralized applications directly from Chrome, Firefox, Brave, or Edge.
Installation and Setup
1) Visit the official MetaMask website (metamask.io) and choose the appropriate browser version. 2) Add the MetaMask Extension to your browser and ensure the publisher is “MetaMask.” 3) After installation, create a new wallet or import an existing one using your Secret Recovery Phrase. 4) Set a strong password and enable additional security settings like biometric login (where available). 5) Backup your recovery phrase offline and never share it.

Security Recommendations
Always verify you are downloading MetaMask from the official website. Avoid using recovery phrases or private keys on phishing sites or fake extensions. Enable password protection, lock your wallet when inactive, and consider using a hardware wallet for large asset holdings. Regularly update the extension to ensure the latest security improvements and bug fixes are applied.
