Quick answers
Frequently asked questions
1How do I recover my assets if I lose access to my device or browser profile?⌄
Your assets are secured by your 12-word seed phrase (Secret Recovery Phrase). If you lose access to your device, you can restore your wallet on any new device by installing the extension and entering this phrase. Without it, recovery is impossible.
2Can I use MetaMask to interact with blockchains other than Ethereum mainnet?⌄
Yes, MetaMask supports all EVM-compatible networks. You can manually add custom RPC networks like Polygon, Binance Smart Chain, Arbitrum, or Avalanche by entering their network details in the settings, allowing you to manage assets and interact with dApps on those chains.
3Does MetaMask charge any fees for transactions or usage?⌄
MetaMask itself does not charge fees for its service. However, all transactions on blockchain networks incur 'gas fees,' which are paid to network validators. MetaMask provides an interface to estimate and adjust these gas fees before confirming a transaction.
4Is my private key stored on MetaMask's servers, or is it a custodial wallet?⌄
MetaMask is a non-custodial wallet. Your private keys are encrypted and stored locally on your device, not on MetaMask's servers. This means you have sole control over your funds, but also full responsibility for securing your seed phrase.
5How does MetaMask compare to using a centralized exchange wallet for crypto investing?⌄
MetaMask provides self-custody, meaning you control your private keys and assets directly, enabling interaction with dApps. Centralized exchange wallets are custodial; the exchange holds your keys and assets, offering convenience but limiting direct dApp interaction and introducing counterparty risk.
