How to Trigger a Network Change on OP_WALLET

OP_WALLET allows developers to programmatically request a network change through the switchNetwork method. This is useful for ensuring that users are on the correct network for specific operations, such as interacting with smart contracts or sending transactions.

---

Method

switchNetwork(network: UnisatNetwork): Promise<void>;

• Parameters:

  • network: UnisatNetwork: The network to switch to (testnet, mainnet, or regtest).

---

Example Code

import { UnisatNetwork } from "@btc-vision/transaction";

await opnet.switchNetwork(UnisatNetwork.regtest);

console.log("Network switched to regtest.");

tip

Use getNetwork() to check the current network before requesting a change:

const currentNetwork = await opnet.getNetwork();

if (currentNetwork !== UnisatNetwork.regtest) {
  await opnet.switchNetwork(UnisatNetwork.regtest);
}

Best Practices

• Notify users when a network switch is requested and completed.
• If the network switch fails (e.g., unsupported network), display an appropriate error message to the user.
