Collect browser console and network logs for troubleshooting

Browser console and network logs help Phantom Support diagnose extension issues. These are different from app logs and are collected through your browser's developer tools. You'll need a Chromium-based browser such as Chrome, Brave, Opera, or Microsoft Edge.

Before you start

Use a Chromium-based browser such as Chrome, Brave, Opera, or Microsoft Edge.

Collect console output

1. Open a new tab and go to chrome://extensions/
2. Find the Phantom extension and click Details.
3. Turn on Developer mode in the upper-right corner.
4. Under Inspect views, click service worker.
5. In the new DevTools window, click the Console tab.
6. Click the Clear button (🚫) to remove any previous logs.

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.
