Collect Network logs

1. Go to chrome://extensions/

3. Turn on Developer mode in the upper-right corner.
4. Under Inspect views, click service worker.
5. In the DevTools window, click the Network tab.

If logs don’t appear

If the Console or Network tabs under popup.html show no activity, try right-clicking anywhere inside the Phantom extension’s interface (like the Swap tab) and select Inspect. This opens another DevTools window tied to that specific UI, which should show logs in real time.
