Frequently Asked Questions

Why does my Coinbase Wallet show a network mismatch error?
This error appears when the dApp you're trying to use requires a different blockchain network than the one currently active in your Coinbase Wallet. Each dApp is built for specific networks, so you must switch to match their requirements.
Can I use the same wallet address on different networks?
Yes, your wallet address remains the same across compatible networks, but your token balances and transaction history will be different on each network. Tokens on one network cannot be directly used on another network.
What networks does Coinbase Wallet support?
Coinbase Wallet supports major networks including Ethereum, Polygon, Arbitrum, Optimism, BSC, and many others. You can view all supported networks in your wallet's network settings menu.
Will switching networks affect my crypto balance?
Switching networks will show different token balances because each network has separate ecosystems. Your tokens remain safe on their respective networks and will reappear when you switch back to the correct network.
How do I know which network a dApp uses?
Most dApps display their supported network prominently on their homepage or in their documentation. Look for network logos, names like 'Built on Ethereum' or 'Polygon dApp', or check the dApp's help section for network requirements.
