Are you frustrated by encountering an internal JSON-RPC error while using MetaMask or exploring sidechains and custom networks? Don’t worry; we’ve got you covered with a comprehensive guide. We’ll explain what causes these errors and provide step-by-step solutions to help Fix Internal JSON-RPC Error with ease.
Summary
Internal JSON-RPC errors occur when there’s a communication breakdown between programs using the JSON-RPC protocol. These issues often arise with MetaMask and other crypto wallets when interacting with sidechains, custom networks, or hardware wallets. By following the troubleshooting steps and best practices outlined in this guide, you can effectively resolve internal JSON-RPC errors and ensure a smooth experience while navigating the world of decentralized applications and blockchain networks.
What is Internal JSON-RPC Error?
JSON-RPC (JavaScript Object Notation – Remote Procedure Call) is a protocol that enables programs to communicate and share data using a simple, easy-to-understand format. It combines JSON’s data format for packaging requests and responses with RPC’s method for calling functions on a server from an app and receiving the desired outcomes.
An internal JSON-RPC error occurs when two programs attempting to communicate using this protocol fail to do so properly. The error message signifies that something went wrong inside one of the programs during the communication process, preventing the successful exchange of data.
Why Internal JSON-RPC Error Occurs?
There are several reasons why an internal JSON-RPC error might occur:
- Incorrect network configuration: Adding a network to your wallet with the wrong details can lead to communication issues and trigger the error.
- Insufficient native tokens: When making transactions, you need enough native tokens of the specific network to cover gas fees. A lack of sufficient tokens can cause the error.
- Outdated wallet software: Using an older version of your wallet app or browser extension may result in compatibility problems and JSON-RPC errors.
- Improperly connected hardware wallet: If your hardware wallet (e.g., Ledger) is not properly connected to your wallet software (e.g., MetaMask), communication via JSON-RPC can fail.
- Mistake in the program’s code: An error in the program’s code can prevent proper communication and lead to JSON-RPC errors.
- Incorrect settings: Misconfigurations or settings that are not properly set up can hinder the smooth communication between programs.
How to Fix Internal JSON-RPC Error on MetaMask
To resolve internal JSON-RPC errors on MetaMask, follow these steps:
- Ensure proper network configuration:
- Double-check that you’ve added the network correctly.
- Use ChainList to automatically add networks to your MetaMask wallet, minimizing the risk of errors.
- If manually adding a network, carefully enter the details and verify their accuracy.
- If the error persists, try removing the network from your wallet and re-adding it using ChainList or manual configuration.
- Verify sufficient native tokens:
- Make sure you have enough native tokens of the network you’re transacting on to cover gas fees.
- If your wallet lacks sufficient tokens, send additional native tokens to your MetaMask wallet address.
- Once you have enough tokens to cover the gas fees, attempt the transaction again.
- Update MetaMask:
- Ensure you’re using the latest version of the MetaMask app or browser extension.
- Visit the official MetaMask website or your device’s app store to check for updates.
- Update MetaMask to the most recent version to resolve potential compatibility issues.
5. Properly connect hardware wallet:
If using a Ledger device, follow these steps to establish a proper connection:
- Open your web browser and locate the MetaMask icon.
2. Click on the top right corner button and select “Settings” from the dropdown menu.
3. In the Settings section, click on “Advanced.”
4. Find the “Preferred Ledger connection type” option and select “Ledger Live” from the dropdown menu to enable the Ledger Live bridge.
5. Return to your MetaMask wallet, press on your account, and select “Hardware Wallet.”
6. Choose “Ledger” from the options and click “Connect.”
7. An “Open Device Bridge” window will appear in Ledger Live. Click “Open” to activate the bridge between Ledger Live and MetaMask.

Best Practices for Handling Sidechains and Custom Networks
When working with sidechains or custom networks, keep these best practices in mind to avoid JSON-RPC errors:
- Do your research: Understand the security guarantees and potential risks associated with the network before moving significant assets. Custom networks may offer faster and cheaper transactions but may have different security guarantees than the mainnet.
- Trust the network provider: Only interact with reputable network providers to minimize the risk of malicious activity or compromised transactions. A malicious provider can misrepresent the state of the blockchain, withhold transactions, and potentially record your activity and IP address.
- Verify network information: Carefully check the accuracy of network details when adding them to your wallet. Use trusted sources like ChainList to add networks automatically, or follow verification guidelines if available when adding manually.
- Use established bridges or portals: Rely on trusted bridges or portals to safely transfer tokens between different networks. MetaMask does not track cross-network transactions, so exercise caution and trust the network operator and the Ethereum address you’re sending funds to.
- Avoid direct token transfers: Do not attempt to send tokens directly from one network to another, as this can lead to permanent and irreversible loss of assets. Always use designated bridges for safe asset transfers.
- Understand gas fees: Be aware that transaction fees are paid in the native token of the specific network you’re using. Ensure you have enough native tokens to cover gas fees for sending or swapping transactions.
Conclusion
Resolving internal JSON-RPC errors requires a systematic approach to troubleshooting. By ensuring proper network configurations, maintaining sufficient native tokens, keeping your wallet software up-to-date, and following best practices for sidechains and custom networks, you can overcome these errors and enjoy a seamless experience with your crypto wallet.
FAQs
What is the JSON-RPC protocol?
JSON-RPC is a protocol that defines a format for programs to communicate and exchange data using JSON (JavaScript Object Notation) as the data format and RPC (Remote Procedure Call) as the communication method.
How can I avoid internal JSON-RPC errors when using custom networks?
To minimize the risk of JSON-RPC errors with custom networks, thoroughly research the network’s reputation, use trusted sources for configuration details, and follow established best practices for managing assets across different networks.
Can internal JSON-RPC errors cause permanent loss of funds?
In most cases, internal JSON-RPC errors do not directly cause loss of funds. However, attempting to transfer tokens directly between different networks without using proper bridges can lead to permanent loss of assets.
What should I do if I encounter an internal JSON-RPC error on MetaMask?
If you encounter an internal JSON-RPC error on MetaMask, ensure that the network has been added correctly, you have enough native tokens to cover gas fees, your MetaMask app or extension is updated to the latest version, and your hardware wallet (if applicable) is properly connected. Following the troubleshooting steps outlined in this guide should help you resolve the error.
