How do I install the MetaMask Chrome Extension?
Visit the Chrome Web Store or go directly to the official MetaMask® website and click the download link for Chrome. Then click "Add to Chrome" to install the extension. After installation, follow the setup wizard to create or import your wallet.
Is MetaMask Extension free to use?
Yes, the MetaMask® Extension is completely free to download and use. However, blockchain transactions still require paying network gas fees, which are determined by the Ethereum network, not by MetaMask®.
How do I recover my wallet if I lose access?
During the initial setup, you received a secret recovery phrase (12 or 24 words). This phrase can be used to restore your wallet on any device. Keep this phrase secure and never share it with anyone, as it provides complete access to your funds.
Can I use MetaMask Extension on multiple browsers?
Yes, you can install MetaMask® on multiple browsers and devices. Your wallets will not sync automatically between installations, but you can import the same wallet to multiple devices using your secret recovery phrase.
What's the difference between MetaMask Extension and the mobile app?
The extension is designed for browser use and integrates directly with web-based dApps. The mobile app includes a built-in dApp browser for mobile applications but doesn't integrate with your desktop browser. Many users utilize both for different purposes.
How secure is MetaMask Extension?
MetaMask® employs robust security measures including local encryption of private keys and seed phrases. However, security also depends on user practices: never share your recovery phrase, use strong passwords, and be cautious about which sites you connect your wallet to.
