CryptoWorld News reports that Polymarket has denied the claims made by dark web user “xorcat” alleging a customer data breach. It said that the information referenced has long been publicly accessible via its API and on-chain data, and is not the result of unauthorized access. The platform also rejected allegations that it lacks a vulnerability reward program. Security researchers have questioned the breach claims, suggesting the data may have been scraped from public sources rather than leaked from internal systems. Polymarket stated that transparency is a core feature of blockchain systems, and that transaction and market data can be openly audited by anyone. The platform mocked the hacker’s allegations on social media, saying that publicly available data was merely collected and repackaged, not leaked. Polymarket also noted that its vulnerability reward program was launched on April 16 and has already received hundreds of submissions, weakening the credibility of the hacker’s narrative.
