How to Listen for Network Changes on OP_WALLET

Monitoring network changes in OP_WALLET is essential for applications that need to adapt to different blockchain environments. This guide explains how to listen for network change events using OP_WALLET's on() method.

---

Method

on(event: "chainChanged" | "networkChanged", listener: (network: UnisatNetwork) => void): void;

• Parameters:

  • event: "chainChanged" | "networkChanged": The event to listen for.
  • listener: (network: UnisatNetwork) => void: The callback function to execute when the event is triggered.

---

Example Code

opnet.on("chainChanged", (chainId) => {
  console.log("Network changed to:", chainId);
});

---

Best Practices

• Ensure window.opnet is available before registering event listeners.
• Use the chainId to adapt your application to the correct network settings.
• Use the removeListener method to avoid memory leaks when the listener is no longer needed:

  opnet.removeListener("chainChanged", listener);
