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

RPC, short for Remote Procedure Call, 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 various networks (such as testnets or custom EVM-compatible chains) that aren’t pre-installed in the wallet. This is particularly useful for developers or users exploring new or niche blockchain ecosystems.

Custom RPCs allow manual connectivity between the OKX Web3 Wallet and blockchain networks not supported by default. This is ideal for accessing testnets, EVM-compatible niche chains, or private networks. Follow the steps below to add a custom RPC to your OKX Wallet (web or extension):

Steps to Add Custom RPC

Via Mobile App

1. Open the 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 network details:

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

Your custom RPC network will now appear in the network list.

Key Considerations

• ✅ Use Trusted RPC URLs: Ensure endpoints are from reliable sources.
• ❌ Avoid Incorrect Chain IDs: Wrong IDs may disrupt wallet functionality.
• 🔄 Edit/Remove Networks: Adjust or delete custom RPCs in network settings.
