A Remote Procedure Call (RPC) is a protocol that enables your OKX Web3 Wallet to communicate with a specific blockchain network. By adding a custom RPC, you can manually connect to unsupported networks (like testnets or custom EVM-compatible chains) not preloaded in the wallet. This tool is particularly useful for developers or users exploring niche or emerging blockchains.
Why Use Custom RPC?
Custom RPC allows your OKX Web3 Wallet to interact with blockchains not natively supported. Key use cases include:
- Accessing testnets (e.g., Sepolia, Goerli).
- Connecting to private chains or EVM-compatible networks.
- Exploring lesser-known blockchains.
Step-by-Step Guide to Add Custom RPC
1. Via OKX Mobile App
- Download the OKX Web3 Wallet app.
- Tap the network dropdown at the top of the wallet interface.
- Select Custom or Add Network.
Enter the following details:
- Network Name (e.g., "My Testnet").
- New RPC URL (HTTPS endpoint).
- Chain ID (e.g., 11155111 for Sepolia).
- Currency Symbol (optional, e.g., ETH).
- Block Explorer URL (optional).
- Click Save.
2. Via Web Browser Extension
- Log in to your OKX Web3 Wallet.
- Click the network selector (e.g., Ethereum, BNB Chain).
- Choose Add Network.
- Fill in the same details as above.
- Confirm by clicking Save.
Important Notes
🔹 Always use RPC URLs from trusted sources.
🔹 Incorrect Chain IDs or RPC endpoints may disrupt wallet functionality.
🔹 Custom RPCs can be edited/deleted later in network settings.
