Frequently Asked Questions (FAQ)
1. What is the MetaMask extension used for?
The MetaMask extension is primarily used as a cryptocurrency wallet for managing Ethereum and other ERC-20 tokens. It also functions as a gateway to access Web3 applications, enabling users to interact with decentralized exchanges, games, DeFi protocols, and NFT platforms directly from the browser.
2. How secure is MetaMask?
MetaMask is a non-custodial wallet, meaning it does not store your private keys or personal information. Your keys are stored locally on your device, and you control them. However, you should always protect your secret recovery phrase and use a strong password to enhance security. Never share your private keys with anyone.
3. Can I store Bitcoin on MetaMask?
No, MetaMask supports only Ethereum and Ethereum-based tokens (ERC-20). If you want to store Bitcoin, you would need a Bitcoin wallet like Coinbase or Ledger. However, there are wrapped Bitcoin versions (WBTC) on the Ethereum network that can be stored on MetaMask.
4. How do I send cryptocurrency using MetaMask?
To send cryptocurrency, open MetaMask, click on the "Send" button, and enter the recipient's address. Select the token you wish to send, input the amount, and confirm the transaction. MetaMask will ask for your password to finalize the transaction.
5. What happens if I lose my MetaMask password?
If you lose your MetaMask password, you can still recover your wallet using your secret recovery phrase (12-word backup). Make sure to keep this phrase stored in a secure location to avoid losing access to your wallet.
6. How do I interact with decentralized applications (dApps)?
Once the MetaMask extension is installed, you can connect it to most dApps by clicking the "Connect" or "Login" button on the dApp's website. MetaMask will ask for permission to connect, and you can approve the connection to interact with the dApp.
