Frequently Asked Questions
Q: Why can't I see my MATIC balance after adding the network?
A: Ensure you've both added the correct Polygon network configuration and that MATIC has actually been sent to your wallet address on the Polygon chain.
Q: What's the difference between Mainnet and Testnet?
A: Mainnet handles real MATIC transactions with monetary value. Testnet uses fake MATIC for development/testing purposes.
Q: Is there a mobile setup process for MetaMask?
A: Yes, the same parameters work in the MetaMask mobile app. Navigate to Settings > Networks > Add Network.
Q: How do I troubleshoot failed transactions?
A: First check Polygonscan for transaction status. Ensure you have sufficient MATIC for gas fees (recommend keeping 1-2 MATIC for transactions).
Q: Can I use the same address for Ethereum and Polygon?
A: Yes, your address works across all EVM-compatible chains, but assets exist on separate networks (e.g., ETH on Ethereum, MATIC on Polygon).
