Following the massive $285 million Drift Protocol hack, Circle has come under criticism for its handling of the incident. Prominent blockchain investigator ZachXBT alleged that faster action by Circle could have limited crypto losses by freezing stolen USDC tokens. However, freezing assets without proper legal authorization carries significant legal risks for the stablecoin issuer.

The controversy highlights the ongoing debate about centralized stablecoin issuers' responsibilities and capabilities in responding to DeFi exploits. While technically possible to freeze USDC tokens, such actions must balance rapid response with proper legal procedures to avoid potential liability issues.
