Security Warning

  • Only use RPC URLs from official project documentation or trusted sources like ChainList
  • Double-check Chain IDs before adding - wrong IDs can cause lost transactions
  • Be cautious of phishing sites that mimic legitimate network setup pages

Troubleshooting Common Issues

❌ Network not switching

Try disconnecting and reconnecting your wallet, or restart your browser. Check if the RPC endpoint is responding.

❌ Balance shows 0

You may not have tokens on this network yet. You need to bridge assets from another chain or receive tokens on this specific network.

❌ Transaction pending forever

The network may be congested or RPC may be slow. Try a different RPC endpoint or increase gas price.

❌ "Could not fetch chain ID"

The RPC URL may be incorrect or the endpoint is down. Verify the URL or try an alternative RPC endpoint.
