Remote Procedure Call (RPC) is a protocol that enables your OKX Wallet to communicate with a specific blockchain network. It allows your wallet to send requests to remote nodes (blockchain servers) for executing operations and receiving results without managing complex connection details. Adding a custom RPC endpoint lets you manually connect your wallet to unsupported networks, such as testnets, EVM-compatible private chains, or emerging blockchains. This feature is particularly useful for developers and explorers of niche chains.
Why Use a Custom RPC Endpoint?
- Access experimental or private networks
- Connect to EVM-compatible custom chains
- Explore less mainstream blockchains
- Enhance development and testing capabilities
Steps to Add a Custom RPC Endpoint
Via Mobile App
- Open the OKX Web3 Wallet app
- Tap the network dropdown menu (top of the wallet interface)
- Select Custom or Add Network
Enter these details:
- Network Name: A descriptive label (e.g., "My Testnet")
- New RPC URL: HTTPS endpoint for the RPC service (must be valid and secure)
- Chain ID: Unique network identifier (e.g., 137 for Polygon)
- Currency Symbol (optional): e.g., ETH, BNB
- Block Explorer URL (optional): For transaction tracking
- Click Confirm or Save
Via Browser Extension
- Log in to your OKX Wallet
- Click the network selection tool (top of the interface)
- Choose Add Network
- Fill in the same details as above
- Select Save or Add

Key Considerations
- Use RPC endpoints only from trusted sources
- Incorrect Chain IDs or RPC URLs may disrupt wallet functionality
- Added networks can be modified or removed later via settings
FAQ
What happens if I enter an invalid RPC URL?
Your wallet will fail to connect to the target network. Always verify the URL with official network documentation.
Can I add multiple custom networks?
Yes, OKX Wallet supports multiple custom RPC configurations.
Is there a risk of funds loss with custom RPCs?
No, but transactions on unverified networks may carry higher risks. Double-check all parameters before use.
