Etherscan team launches Orbscan, a Polymarket explorer providing trader PnL tracking and API access.
DeFi & Yields ·
The team behind Etherscan has launched Orbscan, a platform designed to track trader performance and provide application programming interface access for Polymarket, a prediction market protocol. Orbscan functions as an explorer—a tool for viewing and analyzing blockchain activity—tailored specifically to Polymarket users and developers seeking to integrate with the platform's data.
Prediction market explorers serve a similar role to blockchain explorers on general-purpose chains: they surface transaction history, account activity, and derived metrics that raw blockchain data alone does not readily provide. In Polymarket's case, the ability to calculate and display individual trader profit-and-loss figures requires indexing and aggregating position data across multiple trades and resolutions. The addition of API access enables third-party applications to query this information programmatically rather than through a web interface.
What remains unclear is the full scope of data endpoints Orbscan exposes through its API, pricing or rate-limit structures for developers, and whether the platform plans to index historical trader performance retroactively or only from launch forward. The relationship between Orbscan and existing Polymarket infrastructure, including how it sources its data, has not been detailed.
