5. Why Does Chainlist Show an RPC Error? How to Resolve the Issue?
Occasionally, users may encounter RPC errors while using Chainlist to add networks to wallets like MetaMask. These errors can disrupt wallet connectivity and prevent smooth interactions with blockchain networks. This guide identifies common reasons for RPC errors and offers actionable steps to resolve them.

What Is an RPC Error?
An RPC (Remote Procedure Call) error occurs when the wallet fails to communicate with the blockchain network. This can happen due to:
https://chainslist.net
Outdated RPC endpoints.
Network congestion or downtime.
Incorrectly configured network details.
Common Causes of RPC Errors and Fixes
1. Outdated RPC URLs
Cause: The blockchain has updated its RPC endpoints, rendering older ones unusable.
Fix:
Check the blockchain’s official website or GitHub repository for the latest RPC details.
Update your wallet configuration manually if necessary.
2. Network Congestion
Cause: High transaction volume can overwhelm RPC servers, causing timeouts.
Fix:
Wait for network congestion to subside and try again.
Use alternative RPC endpoints from platforms like Ankr or Alchemy.
3. Incorrect RPC Configuration
Cause: Errors in chain IDs, currency symbols, or block explorer URLs can disrupt connectivity.
Fix:
Cross-check all details on Chainlist with the blockchain’s official documentation.
4. Wallet or Browser Issues
Cause: Outdated wallet extensions or conflicting browser settings.
Fix:
Update your wallet to the latest version.
Clear your browser cache or use an incognito window to resolve compatibility issues.
Tips for Preventing RPC Errors
Verify Network Details: Always double-check RPC configurations before adding networks.
Use Reliable Internet Connections: Ensure your connection is stable when interacting with blockchain networks.
Monitor Network Status: Use tools like Blockscan to check for RPC server downtime.
Conclusion
RPC errors on Chainlist can be frustrating, but they’re often easy to resolve with the right steps. By understanding common causes and applying the fixes outlined here, you can restore wallet functionality and maintain seamless blockchain interactions.
