A trader profile on every Polymarket profile page
The PMWallets browser extension adds a card to polymarket.com: open any trader's profile and see how that wallet trades, from data computed on the Polygon chain.
What the card shows
- Judgement tags: two-sided market maker, high win rate (by the lower bound of its confidence interval), profit over $1k in 30 days.
- Execution style (maker, taker or both), trading pace, how recently it traded, and its main market categories.
- Profit, volume and typical fill for that wallet over the last 7 or 30 days — exact to the cent under $1,000, rounded above it.
- Whether the account trades through linked wallets.
Who it is for
Anyone deciding whether a trader they found on Polymarket — in a market's top holders, a comment thread or a social post — is worth following. The card answers in a glance what the profile page does not: is this wallet skilled, lucky, or a market maker.
Install
- Download the extension from pmwallets.com or from GitHub Releases, and unzip it.
- Open chrome://extensions, turn on Developer mode and choose Load unpacked.
- Sign in on pmwallets.com, create an extension key and paste it into the extension's settings.
- Open any profile on polymarket.com — the card appears in the corner.
Private by design
The extension sends only its key and the address of the profile you open to api.pmwallets.com. Nothing else about your browsing leaves the browser. The extension key can only read wallet profiles: it cannot spend money or reach the rest of your account. The code is open source (MIT) with no build step, so what is in the repository is what runs.
Price
Included in every monthly plan — Base $10, Pro $39, Max $99 — with a 7-day free trial on Base. The Chrome Web Store does not list it, so it is installed in developer mode.
