Adding a custom remote procedure call (RPC) to your OKX Wallet unlocks access to blockchain networks beyond the default options. Whether you're a developer testing on a new environment or a Web3 enthusiast exploring emerging EVM-compatible chains, understanding how to configure a custom RPC is essential.
An RPC—short for remote procedure call—acts as a communication bridge between your wallet and a blockchain network. It enables your OKX Wallet to send transactions, read data, and interact with smart contracts on that specific chain. While major networks like Ethereum, BNB Chain, and Polygon are preconfigured, many testnets, private networks, and newer blockchains require manual setup through a custom RPC.
This guide walks you through the process of adding a custom RPC on both the OKX mobile app and the web browser extension, ensuring seamless connectivity across platforms.

Why Use a Custom RPC?
Custom RPCs empower users with greater flexibility and control over their Web3 experience. Here are key reasons to consider using one:
- Access testnets: Developers often need to deploy and test dApps on networks like Goerli, Sepolia, or custom local environments.
- Explore new chains: Early adopters can interact with emerging Layer 1 or Layer 2 blockchains before they’re widely supported.
- Private network integration: Enterprises or development teams may run internal blockchains for specific use cases.
- Avoid congestion: Some users switch to less crowded networks for faster, lower-cost transactions.
By manually configuring an RPC, you're not limited to pre-approved networks—opening doors to innovation and experimentation in the decentralized ecosystem.
Key Information Needed for Custom RPC Setup
Before adding a custom RPC, gather these critical details from the blockchain’s official documentation:
- Network Name: A label for easy identification (e.g., “My Testnet”).
- New RPC URL: Must be a secure HTTPS endpoint (e.g.,
https://rpc.mytestnet.org). - Chain ID: A unique numeric identifier (e.g., 137 for Polygon Mainnet).
- Currency Symbol (Optional): The native token symbol (e.g., TEST, ETH).
- Block Explorer URL (Optional): A link to view transactions (e.g.,
https://explorer.mytestnet.org).
⚠️ Always verify this information from trusted sources such as the project’s official website or GitHub repository. Incorrect inputs can lead to failed transactions or loss of access.
How to Add a Custom RPC on Mobile App
Follow these steps to manually connect your OKX Wallet mobile app to a new network:
- Open the OKX Web3 Wallet app on your device.
- Tap the network dropdown located at the top of the wallet screen.
- Scroll down and select Custom or Add network, depending on your interface version.
Enter the required network details:
- Network name
- RPC URL
- Chain ID
- Optional: Currency symbol and block explorer URL
- Review all entries carefully.
- Tap Confirm or Save to complete the setup.
Once saved, the new network will appear in your network list and can be selected anytime.
How to Add a Custom RPC on Web Extension
The process is equally straightforward on the browser extension:
- Launch your browser and open the OKX Wallet extension.
- Click on the current network selector—usually displayed at the top (e.g., "Ethereum", "BNB Chain").
- Choose Add network from the dropdown menu.
Fill in the following fields:
- Network name: Assign a recognizable name.
- New RPC URL: Input the HTTPS endpoint provided by the network.
- Chain ID: Enter the correct chain ID (double-check this value).
- Currency symbol (optional): Define the native token symbol if desired.
- Block explorer URL (optional): Add a transaction explorer link for transparency.
- Click Save or Add.
Your wallet will now recognize the network, allowing you to switch to it instantly.
Frequently Asked Questions (FAQ)
What is a custom RPC in OKX Wallet?
A custom RPC allows you to manually connect your OKX Wallet to a blockchain network not included by default. This is commonly used for testnets, private chains, or new EVM-compatible networks.
Is it safe to add a custom RPC?
Yes—but only if you trust the source of the RPC URL and network details. Malicious endpoints could potentially expose transaction data. Always use official documentation when obtaining configuration details.
Can I edit or remove a custom RPC later?
Absolutely. Within your OKX Wallet settings, navigate to network management where you can modify or delete any custom RPC configuration at any time.
What happens if I enter the wrong Chain ID?
An incorrect Chain ID may result in transaction failures or display errors. The wallet relies on this ID to identify the correct blockchain, so accuracy is crucial.
Do I need technical knowledge to add a custom RPC?
Basic familiarity with blockchain concepts helps, but the process itself is user-friendly. As long as you have accurate network details, even non-developers can successfully add a custom RPC.
Will adding a custom RPC affect my funds on other networks?
No. Your assets remain isolated per network. Adding a new RPC only expands connectivity—it doesn’t move or interact with existing balances unless you initiate a transaction.

Best Practices for Managing Custom RPCs
To ensure security and reliability while using custom networks:
- Verify all details independently: Cross-check Chain ID, RPC URL, and explorer links via official channels.
- Use HTTPS only: Never input an HTTP-based RPC URL; it lacks encryption and poses security risks.
- Label clearly: Use descriptive names to avoid confusion between similar testnets or forks.
- Test first: Send a small transaction before deploying larger interactions.
- Keep backups: Note down your configurations externally in case of app resets.
Final Thoughts
Configuring a custom RPC in OKX Wallet is a powerful feature that enhances your ability to engage with diverse blockchain ecosystems.
