chrome://extensions/ - Find the Phantom extension and click Details.
- Turn on Developer mode in the upper-right corner.
- Under Inspect views, click service worker.
- In the new DevTools window, click the Console tab.
- Click the Clear button (🚫) to remove any previous logs.
- Reproduce the issue.
- After reproducing the issue, right-click inside the Console and select Save as… to export a LOG file.
- Share this file with the Phantom Support team.

chrome://extensions/and turn Developer mode off.

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.
