MetaMask® Wallet FAQs

1. Is MetaMask® Wallet free to use?

Yes, the MetaMask® Wallet download and usage are completely free. However, blockchain transactions require gas fees paid in the native token of the network you're using (ETH for Ethereum, MATIC for Polygon, etc.).

2. Can I access my wallet from multiple devices?

Yes, by using your secret recovery phrase to import your wallet on another device. Your MetaMask® login password is device-specific, but the recovery phrase gives access across all platforms.

3. What's the difference between the extension and mobile app?

The MetaMask® Extension is for desktop browsers while the mobile app is for smartphones. Both offer similar functionality, but the mobile app includes a built-in dApp browser.

4. How do I know my MetaMask® Wallet is secure?

Always download from official sources, never share your recovery phrase, use strong passwords, and consider adding a hardware wallet for additional security.

5. Can I use MetaMask® without the extension?

Yes, the mobile app provides full functionality. Some dApps also support WalletConnect for connecting without the MetaMask® Chrome Extension.

6. What happens if MetaMask® stops working?

Your funds are stored on the blockchain, not in MetaMask®. As long as you have your recovery phrase, you can always access your funds through any Ethereum wallet.

Security Tip: Bookmark MetaMask.com to avoid phishing sites, and never enter your recovery phrase on any website.
