FAQ Section
Q1: Why isn’t my BNB balance showing after adding BSC?
A1: Ensure you’ve:
- Funded your wallet with BNB (via transfer or purchase).
- Selected the correct BSC network (not Ethereum).
Q2: Can I use the same MetaMask wallet for Ethereum and BSC?
A2: Yes! Your wallet address works across all supported networks. Only the network setting needs to change.
Q3: Is there a fee for adding new networks?
A3: No—network additions are free. Transactions on each chain incur their respective gas fees (e.g., BNB for BSC).
Q4: How do I remove a network?
A4: Go to Settings > Networks > Select the network > Click "Delete."
Q5: What if I enter wrong RPC details?
A5: Transactions may fail or funds could be lost. Always verify URLs from official sources like Binance Academy.
