PMWallets
PMWallets is a Polymarket smart-money leaderboard built from its own ledger of the Polygon chain. Wallets that trade as one are scored as one trader; win rates come with a 95% confidence interval, profit is shown without the single best market, and published records are never rewritten. Follow any trader and get every fill over WebSocket or signed webhook in about a second, from $0.01 per wallet per hour. API, MIT SDKs, an open-source copy-trading bot and a browser extension.
