FAQ

Frequently Asked Questions

What is MetaMask and how does it work?
MetaMask is a self-custodial crypto wallet that runs as a browser extension. It allows you to store Ethereum and other blockchain assets, swap tokens, and interact with decentralized applications without relying on a centralized service. Your private keys remain on your device at all times. You authenticate transactions with your password, and MetaMask signs them locally before broadcasting to the blockchain.
How do I download and install MetaMask extension?
Visit the official MetaMask website or your browser's extension store (Chrome Web Store, Firefox Add-ons, Edge Add-ons). Search for 'MetaMask' and click 'Add to Browser' or 'Install'. The extension will appear in your browser's toolbar within seconds. Click it to create a new wallet or import an existing one using your seed phrase.
Is MetaMask safe to use?
MetaMask is non-custodial, meaning only you control your funds. Your private keys and seed phrase never leave your device. However, security depends on you. Never share your seed phrase, use a strong password, enable transaction confirmation, and beware of phishing sites. Keep your browser and extension updated. For maximum security, use a hardware wallet with MetaMask.
How do I back up my MetaMask wallet?
When you create a wallet, MetaMask generates a 12-word seed phrase. Write this phrase down and store it offline in a secure location. Never share it with anyone. If you lose your device or browser, you can restore your wallet on any device using this seed phrase. MetaMask does not store this phrase — only you can access it.
Can I use MetaMask on multiple devices?
Yes. You can install MetaMask on different browsers or devices. Import your wallet using your seed phrase on each device. However, each installation is independent — they don't sync automatically. Changes on one device won't appear on another unless you manually refresh. For security, use hardware wallet pairing across devices.

TESTIMONIALS

What Users Say

Sarah M., California
Been using MetaMask for 3 years. The extension is intuitive and reliable. Token swaps are fast and the multi-network support saved me hours of manual bridge transactions. Highly secure when you follow best practices.
Alex K., Texas
Perfect for Web3 trading and NFT purchases. The dApp connection is seamless and gas fees are transparent. I paired it with my Ledger and feel completely secure with my holdings.
Jordan L., New York
Great wallet overall. The interface could be slightly more beginner-friendly, but once you understand it, everything works smoothly. Customer support via Discord and Twitter is responsive and helpful.
