Quick Facts
- Check Node Configuration: Verify that your zkSync node is properly configured. Incorrect configuration can lead to unknown RPC error.
- Network Connectivity: Ensure that your zkSync node has a stable connection to the zkEVM network. Loose or broken connections can cause errors.
- Node Software Version: Make sure your zkSync node is running the latest version of the software. Installing updates often resolves compatibility issues.
- RPC Server Status: Check the status of your zkSync RPC server. A faulty or non-functional RPC server can cause unknown errors.
- Request Data Validation: Validate the request data sent to the zkSync RPC server. Malformed requests can cause unknown errors.
- Error Log Inspection: Inspect the zkSync error logs to identify the root cause of the unknown RPC error. Logs can provide valuable insights into the issue.
- Node Restart: Restart your zkSync node to re-initialize the RPC server and resolve any temporary errors.
- Request Retry: Retry the original request to the zkSync RPC server. Sometimes, errors can be resolved by simply retrying the request.
- Compatibility Issues: Check for compatibility issues with other systems or services connected to your zkSync node. Conflicting configurations can cause unknown errors.
- Contact Support: If none of the above steps resolve the issue, contact the zkSync support team or a professional developer for further assistance.
Fixing Unknown RPC Error on zkSync: A Step-by-Step Guide
Are you tired of encountering unknown RPC errors on zkSync? You’re not alone. These errors can be frustrating, especially when you’re in the middle of a trading session. In this article, we’ll show you how to fix unknown RPC errors on zkSync and get back to trading in no time.
What is an RPC Error?
Before we dive into the fix, let’s quickly discuss what an RPC error is. RPC stands for Remote Procedure Call, which is a protocol that allows different systems to communicate with each other. In the context of zkSync, RPC errors occur when there’s a problem with the communication between your trading platform and the zkSync network.
Common Causes of RPC Errors
RPC errors can be caused by a variety of factors, including network connectivity issues, incorrect API keys or permissions, insufficient gas or funds, bug in the trading platform or zkSync network.
Step 1: Check Your Network Connection
A stable network connection is essential for trading on zkSync. If your internet connection is slow or unstable, you may encounter RPC errors. Here’s how to check your network connection:
- Check your internet speed using a tool like Speedtest.
- Restart your router or modem.
- Switch to a different network or use a mobile hotspot.
| Item | Description |
|---|---|
| Internet Speed | At least 10 Mbps |
| Network Stability | No packet loss or latency |
| Router or Modem | Restarted recently |
Step 2: Verify Your API Keys and Permissions
Incorrect API keys or permissions can also cause RPC errors. Make sure to:
- Double-check your API keys and permissions.
- Ensure that your API keys are up-to-date and not expired.
- Contact zkSync support if you’re unsure about your API keys or permissions.
| API Key | Description |
|---|---|
| API Key Type | Read-only or read-write |
| API Key Expiration | Not expired |
| API Key Permissions | Correctly configured |
Step 3: Check Your Gas and Funds
Insufficient gas or funds can also cause RPC errors. Here’s how to check your gas and funds:
- Check your gas balance using the zkSync explorer.
- Ensure that you have sufficient funds to cover transaction fees.
- Top up your gas balance if necessary.
| Item | Description |
|---|---|
| Gas Balance | Sufficient gas to cover transaction fees |
| Funds | Sufficient funds to cover transaction fees |
| Transaction Fees | Correctly calculated |
Step 4: Update Your Trading Platform
If you’re using a trading platform, make sure to update it to the latest version. Outdated platforms can cause RPC errors due to compatibility issues. Here’s how to update your trading platform:
- Check the Trading Onramp blog for updates.
- Follow the update instructions provided by your trading platform.
- Restart your trading platform after updating.
| Platform | Update Instructions |
|---|---|
| Trading Onramp | Check the blog for updates |
| Other Platforms | platform-specific update instructions |

FAQ: Fixing Unknown RPC Error on zkSync
Q: What is an Unknown RPC error on zkSync?
An Unknown RPC error on zkSync occurs when the zkSync node is unable to process a request due to an unknown or invalid request format. This error is usually caused by a mismatch between the client’s request and the zkSync node’s expected request format.
Q: How to fix Unknown RPC error on zkSync?
If you encounter an Unknown RPC error on zkSync, follow these steps to troubleshoot and resolve the issue:
Step 1: Check zkSync Node Logs
Check the zkSync node logs for any errors or warnings related to the Unknown RPC error. You can find the logs in the
Analyze the logs to identify any patterns or clues that might help you resolve the issue.
Step 2: Verify Request Format
Verify that the request format sent by your client (e.g. web3.js, Ethers.js, etc.) is correct and matches the expected format for the RPC endpoint being called.
Check the zkSync documentation to ensure that you are using the correct request format and parameters for the endpoint being called.
Step 3: Check ZkSync Node Configuration
Check the zkSync node configuration file (zkSync_config.toml or zkSync_config.json) to ensure that the RPC endpoint is correctly configured and listening on the expected port.
Verify that the zkSync node to re-establish connections and re-sync data.
Step 4: Restart ZkSync Node
Restart the zkSync node to re-establish connections and re-sync data.
Attempt to call the RPC endpoint again to see if the error is resolved.
Step 5: Contact zkSync Support
If none of the above steps resolve the issue, contact zkSync support for further assistance.
Provide logs and detailed information about the error and your setup to help their team debug and resolve the problem.
Q: What are some common causes of Unknown RPC error on zkSync?
Some common causes of Unknown RPC error on zkSync include:
- Mismatched request format between client and zkSync node
- Incorrect zkSync node configuration
- zkSync node not properly synced with the Ethereum mainnet or other source of truth
- Complex issues with data storage or caching on the zkSync node>
Q: How can I prevent Unknown RPC error on zkSync?
To prevent Unknown RPC error on zkSync, ensure that:
- Your client’s request format matches the expected format for the RPC endpoint being called
- Your zkSync node configuration is correct and up-to-date
- Your zkSync node is properly synced with the Ethereum mainnet or other source of truth
