anchored·4MU5F9…3LQXSummary
PolyArb is a crypto product marketed as a prediction-market arbitrage bot for platforms like Polymarket, but was publicly identified by on-chain investigator ZachXBT on May 4, 2026 as a fraudulent front containing an active wallet drainer. Independent phishing-domain trackers separately flagged associated domains (including polyarb.io) as malicious. The operation surfaced amid a broader wave of phishing targeting prediction-market users in 2026, though PolyArb itself is a distinct scheme from the unrelated Polymarket comment-section phishing campaign that cost users over $500,000.
