MetaMask is one of the most popular browser-based cryptocurrency wallets and Web3 gateways. It allows users to securely manage Ethereum, ERC-20 tokens, and other blockchain assets directly from a web browser such as Chrome, Firefox, Brave, or Edge. By integrating seamlessly with decentralized applications (dApps), MetaMask provides a bridge between traditional web browsing and blockchain ecosystems, allowing you to send, receive, stake, and interact with smart contracts without exposing private keys to the internet.

The installation process is straightforward but requires care to ensure security. Follow these steps:
- Visit the official MetaMask website: https://metamask.io/download/
- Select your browser: Chrome, Firefox, Brave, or Edge.
- Click “Install” or “Add to Browser.” Follow the browser’s prompts to confirm installation.
- Once installed, pin the MetaMask extension for easy access. In Chrome or Edge, click the puzzle icon in the toolbar, then pin MetaMask.
- Verify the extension by checking the MetaMask logo and ensuring the source is official.
Security tip: Avoid downloading MetaMask from third-party websites or unverified browser stores. Only use the official source to prevent malware or phishing attacks.
Setting Up Your MetaMask Wallet
After installation, setting up your wallet properly is critical for security and usability. MetaMask offers two options: creating a new wallet or importing an existing wallet using a Secret Recovery Phrase.
Create a New Wallet
- Open the MetaMask extension.
- Click “Get Started” and choose “Create a Wallet.”
- Set a strong password for local access. This password protects the extension on your browser, but not your blockchain assets themselves.
- Write down your 12-word Secret Recovery Phrase on paper. Do not store it digitally.
- Confirm the recovery phrase within the extension to complete the setup.
Import an Existing Wallet
- Choose “Import Wallet” from the MetaMask setup screen.
- Enter your existing Secret Recovery Phrase.
- Create a new password for local access.
- Confirm setup, and your existing wallet will be restored.
Tip: Always back up your Secret Recovery Phrase offline. Losing it means losing access to your wallet and assets permanently.
