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

Remote Procedure Call (RPC) is a protocol that enables your OKX Wallet to communicate with a specific blockchain network. By adding a custom RPC, you can manually connect to different networks—such as testnets or EVM-compatible custom chains—that aren't preloaded in the wallet. This feature is particularly valuable for developers or users exploring emerging or niche blockchains.

Custom RPCs allow you to manually link your OKX Web3 Wallet to a blockchain network unsupported by default. Follow these steps to add a custom RPC to your OKX Wallet (app or extension):

Via Mobile App

1. Open your OKX Web3 Wallet app.
2. Tap the network dropdown menu at the top of the wallet interface.
3. Select Custom or Add Network.

4. Enter the following details:

   • Network Name: Assign a unique name (e.g., "My Testnet").
   • New RPC URL: A valid HTTPS endpoint for the custom RPC.
   • Chain ID: The network’s unique identifier (e.g., 137 for Polygon).
   • Currency Symbol (Optional): ETH, BNB, etc.
   • Block Explorer URL (Optional): For transaction tracking.
5. Click Confirm or Save.

Via Browser Extension

1. Log in to your OKX Wallet extension.
2. Click the network selector (e.g., Ethereum, BNB Chain).
3. Choose Add Network.
4. Input the same details as above.
5. Select Save or Add. Your custom RPC network will now appear in the network list.

Key Considerations

• Verify RPC Sources: Ensure the URL is from a trusted provider.
• Accuracy Matters: Incorrect Chain IDs or RPC endpoints may disrupt wallet functionality.
• Editable Networks: Custom RPCs can be modified or deleted later in network settings.

For troubleshooting, consult the official documentation of the target network or contact OKX support.
