PredictionToolkitWhat is PolymarketScan?
Category rankings help investigate a trader’s results within a market tag instead of relying only on overall P&L. Open the wallet’s positions and history to understand that slice of activity, or start with a market and inspect its holders and activity where available. Keep the chosen period and category with any comparison.
The homepage whale tape polls at roughly 60-second intervals, while unauthenticated agent access has a separate limit of 60 requests per minute. Paper-arena results describe simulation, not live account execution. Any airdrop estimate displayed by the product is a model output rather than an earned entitlement.
Who it is for
- Researching traders in a specific market category.
