MetaMask® Wallet FAQ

Q1: Is MetaMask® free to use?

Yes! The wallet is free. You only pay blockchain gas fees for transactions.

Q2: Can I recover my wallet if I forget my password?

Yes, but ONLY with your Secret Recovery Phrase. Without it, funds are permanently lost.

Q3: Why do I need ETH to send tokens?

Ethereum requires gas fees (paid in ETH) for all transactions, including token transfers. Other networks use their native coins (e.g., MATIC on Polygon).

Q4: How do I add Binance Smart Chain?

Open Extension → Network dropdown → "Add network"
Use official BSC parameters:
Network Name: BNB Smart Chain
RPC URL: https://bsc-dataseed.binance.org/
Chain ID: 56

Block Explorer: https://bscscan.com

Mobile offers better isolation from desktop malware, but both are secure when used properly. Always enable biometric locks on mobile.

Connect Ledger® via USB (Enable Blind Signing)
In MetaMask® Extension → Account icon → "Connect Hardware Wallet"
