How to Add a Custom Remote Procedure Call (RPC) to OKX Web3 Wallet?

·

Adding a custom Remote Procedure Call (RPC) to your OKX Web3 Wallet unlocks access to a broader range of blockchain networks beyond those pre-configured in the wallet. Whether you're a developer testing on a new network, an early adopter exploring emerging EVM-compatible chains, or someone interacting with private blockchains, understanding how to manually configure RPC settings is essential.

This guide walks you through the step-by-step process of adding a custom RPC endpoint to the OKX Web3 Wallet—available both as a mobile app and browser extension—while highlighting best practices, common pitfalls, and key considerations for security and performance.

What Is a Remote Procedure Call (RPC)?

A Remote Procedure Call (RPC) is a protocol that enables your wallet to communicate with a specific blockchain network. In simple terms, it acts as a bridge between your OKX Web3 Wallet and the blockchain, allowing you to send transactions, check balances, and interact with decentralized applications (dApps).

By default, OKX Wallet supports major networks like Ethereum, BNB Chain, Polygon, and others. However, not all blockchains—especially testnets, private networks, or newer EVM-compatible chains—are automatically included. That’s where custom RPC configuration comes in.

Why Add a Custom RPC?

There are several scenarios where manually adding an RPC endpoint becomes necessary:

Custom RPCs give you greater control and flexibility over which networks you can interact with directly from your wallet.

Key Information Needed for Custom RPC Setup

Before adding a custom network, gather the following details:

Ensure all information is accurate—especially the Chain ID and RPC URL—to avoid connection failures.

How to Add a Custom RPC on the OKX Web3 Wallet App

Follow these steps to configure a custom RPC on the mobile version of the OKX Wallet:

  1. Open the OKX Web3 Wallet app on your smartphone.
  2. Tap the network selector dropdown at the top of the wallet interface (usually showing “Ethereum,” “BNB Chain,” etc.).
  3. Scroll down and select “Custom” or “Add Network.”

  4. Enter the required network details:

    • Network Name
    • RPC URL
    • Chain ID
    • Currency Symbol (optional)
    • Block Explorer URL (optional)
  5. Tap “Confirm” or “Save.”

Once saved, the new network will appear in your network list and can be selected anytime.

How to Add a Custom RPC on the OKX Web3 Browser Extension

The process on the browser extension is similarly straightforward:

  1. Open your browser and navigate to the OKX Web3 Wallet extension.
  2. Click on the network selector at the top of the wallet panel.
  3. Choose “Add Network” from the dropdown menu.

  4. Fill in the following fields:

    • Network Name: Assign a recognizable name.
    • New RPC URL: Input a valid HTTPS endpoint (e.g., https://rpc.examplechain.org).
    • Chain ID: Enter the correct numeric identifier.
    • Currency Symbol: Optional, but helpful for clarity.
    • Block Explorer URL: Optional; enables transaction tracking.
  5. Click “Save” or “Add.”

Your custom network is now active and ready for use.

Frequently Asked Questions (FAQ)

Can I edit or delete a custom RPC network later?

Yes. You can manage your custom networks by going to the Network Settings section in your OKX Wallet. From there, you can edit any field or remove the network entirely.

What happens if I enter the wrong Chain ID?

An incorrect Chain ID may cause transaction failures or prevent the wallet from syncing with the network. Always verify the Chain ID from official sources before entering it.

Is it safe to add custom RPCs?

Only use RPC endpoints from trusted providers. Unreliable or malicious nodes could potentially log your activity or delay transactions. Stick to official network documentation or reputable infrastructure platforms.

Do I need a custom RPC for every dApp I use?

No. Most mainstream dApps automatically detect and suggest supported networks. Custom RPCs are only needed when connecting to unsupported or private chains.

Can multiple custom networks be added?

Absolutely. The OKX Web3 Wallet allows you to store and switch between multiple custom RPC configurations seamlessly.

Will adding a custom RPC affect my funds on other chains?

No. Your assets remain secure and isolated on their respective blockchains. Adding a new network does not transfer or expose funds from other chains.

Best Practices for Using Custom RPCs

👉 Connect securely to any EVM-compatible chain with confidence

Troubleshooting Common Issues

If your custom RPC isn’t working, consider the following:

For persistent issues, consult the blockchain’s official documentation or community channels for updated RPC endpoints and known bugs.

Final Thoughts

Configuring a custom RPC in your OKX Web3 Wallet is a powerful feature that expands your blockchain interoperability. Whether you're building, testing, or simply exploring decentralized ecosystems, this functionality puts you in control of your Web3 experience.

With clear steps, proper verification, and cautious selection of trusted endpoints, you can safely connect to virtually any EVM-compatible network.
