Binance co-founder Changpeng Zhao reported the exchange appears to have been hacked. Tether immediately froze approximately $971 million in USDT. Circle froze $823 million in USDC. The combined freeze totals $1.794 billion in stablecoins, blacklisting the compromised addresses and rendering those tokens unusable.
Zhao said he expects Binance to fully cover all user funds. The exchange will conduct a full internal investigation.
The freeze mechanism employed by Tether and Circle works by blacklisting specific blockchain addresses identified as receiving stolen funds. This centralized control enables rapid response to security incidents but also exposes a key tension in crypto: stablecoin issuers can freeze assets at will, a power that cuts both ways for investors. It stopped the bleeding here. It also means holders are ultimately subject to issuer decisions, not just protocol rules.
For traders holding positions on Binance, the speed of the stablecoin freeze limits contagion—the stolen funds are now locked in place rather than being laundered across exchanges. Zhao's commitment to cover losses is critical; how Binance executes on that promise will determine whether this event fractures confidence in the platform or becomes a contained incident.
