Chrome extension
The X-ray as a small panel on polymarket.com, so you see who is behind a move or a wallet without leaving the page.

Works in Chrome, Edge, Brave and other Chromium browsers. It is not in the Chrome Web Store yet, so it installs as an unpacked extension.
Install in about a minute
- 1Unzip the download into a folder you will keep. Chrome loads it from there, so do not delete the folder afterwards.
- 2Open
chrome://extensions(Edge:edge://extensions, Brave:brave://extensions) and turn on Developer mode, top right. - 3Click Load unpacked and pick the folder you unzipped (the one that holds
manifest.json). - 4Open any Polymarket profile or market. The panel appears at the bottom right; collapse it with the dash, close it with the cross.

Where it shows up
- A profilepolymarket.com/profile/0x… or polymarket.com/@name
- The wallet's label, its edge per bet with an error band, how many bets were scored and its sniping share.
- A market or eventpolymarket.com/event/…
- The latest move of 4 points or more, how much of the money behind it came from proven losers, and the biggest takers with their labels.
- A gamepolymarket.com/sports/<league>/… and /esports/…
- The same market X-ray for the match.
If the panel does not appear
- Reload the Polymarket tab once after installing.
- Click the CALIBRE icon in the toolbar: it says whether the panel is active on this tab, and Show the panel brings back one you closed.
- Still nothing? Open Settings from that popup and press Test connection: it checks that this site answers.
- A wallet audit reads up to 1,000 trades and can take a few seconds the first time.
Updating
Download the zip again, unzip it over the same folder, then press the reload arrow on the extension's card in chrome://extensions.
