Overview
- Late Thursday, October 29, public trackers flagged a rapid outflow from Binance hot wallets and the exchange said its security teams are actively investigating a potential breach while suspending Binance Alpha trading and pausing withdrawals pending checks.
- Binance co‑founder Changpeng Zhao described the pattern as consistent with a hack and the company repeatedly assured users that customer funds remain safe while urging caution against phishing and scam links.
- Stablecoin issuers intervened quickly: Circle froze about $800 million in USDC and Tether froze roughly $1.567 billion in USDT to block movement of funds linked to the incident.
- Separately, Polymarket reported a compromise of an external provider, halted trading, said it fixed the issue and pledged to compensate affected users, illustrating contagion risks from shared vendors.
- Public tallies of stolen amounts vary widely and remain unverified, investigators and platform teams are coordinating with authorities, and markets showed immediate selling pressure as forensic work continues.
