Frequently Asked Questions
What is a self-custodial wallet?
A self-custodial wallet like MetaMask gives you sole ownership and control of your private keys and seed phrase. Unlike exchange wallets, you are entirely responsible for your security, meaning no third party can freeze or access your assets without your permission.
How do I keep my MetaMask wallet secure?
Never share your 12-word seed phrase with anyone, under any circumstances. Avoid storing it digitally; write it down on paper and keep it in a secure location. Be extremely cautious of phishing websites and unsolicited requests to enter your secret recovery phrase. Always verify transaction details before signing.
Can I use MetaMask on multiple devices?
Yes, you can synchronize your wallet across multiple devices by using the "Sync with MetaMask Mobile" feature. This allows you to access your accounts and assets securely from your iPhone, computer, or other supported devices.
What should I do if I think I've been hacked?
If you suspect unauthorized access, immediately move your funds to a new, secure wallet if possible. Since MetaMask is non-custodial, the team cannot reverse transactions. Contact support for guidance, but understand that protecting your seed phrase is the primary line of defense.
Which blockchains does MetaMask support?
MetaMask supports Ethereum and numerous other EVM-compatible networks like Polygon and Arbitrum. It is also expanding support to non-EVM chains like Solana, allowing you to view assets and soon perform more actions.
Is there a cost to use MetaMask?
Downloading and using the MetaMask wallet is free. However, you will still need to pay standard network gas fees for transactions on their respective blockchains, which are determined by network congestion and are not controlled by MetaMask.
