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

Remote Procedure Call (RPC) is a protocol that enables OKX Wallet to communicate with a specific blockchain network. By adding a custom RPC, you can manually connect to networks (such as testnets or custom EVM-compatible chains) not preloaded in the wallet. This is particularly useful for developers or users exploring new or less-known blockchain ecosystems.

Custom RPCs allow you to link your OKX Web3 Wallet to unsupported networks manually. Follow these steps to add a custom RPC in OKX Wallet (web or extension):

In the Mobile App:

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

4. Enter the required details:

   • Network Name: A descriptive name (e.g., "Private Testnet").
   • RPC URL: A valid HTTPS endpoint (e.g., https://custom-rpc.example.com).
   • Chain ID: The unique identifier for the network (e.g., 137 for Polygon).
   • Currency Symbol (optional): e.g., ETH, BNB.
   • Block Explorer URL (optional): For transaction tracking.
5. Tap Confirm or Save.

In the Browser Extension:

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

Important Notes

• Use RPC URLs only from trusted sources.
• Incorrect Chain IDs or RPC endpoints may disrupt wallet functionality.
• Custom networks can be edited or deleted later via network settings.

FAQs

Why should I add a custom RPC?

Custom RPCs let you interact with niche networks (e.g., private testnets, EVM-compatible chains) not natively supported by OKX Wallet.

What if my RPC URL fails?

Verify the URL’s validity and check the network’s official documentation. Contact OKX support if issues persist.

Can I remove a custom RPC later?

Yes. Navigate to network settings and delete unwanted configurations.
