USDC Freeze Controversy: ZachXBT Alleges Circle Missed Real Hacks

Blockchain investigator ZachXBT has accused Circle of failing to act quickly enough to freeze stolen USDC after the Drift Protocol exploit on Solana according to reports. The incident occurred on April 1 and reportedly caused losses between $200 million and $285 million according to data. The Drift Protocol's total value locked dropped by 92.5% as a result, raising questions about the centralized control of USDC and its governance mechanisms according to analysis.

ZachXBT's criticism extends to multiple previous incidents, including the Bybit and Radiant Capital hacks as reported. Over the past three years, losses attributed to Circle's delayed response have exceeded $420 million according to estimates. Critics argue that the centralized control Circle maintains over its Cross-Chain Transfer Protocol (CCTP) gives it the tools to act swiftly, but delays have led to significant financial consequences according to analysis.

The stolen funds were reportedly moved off Solana via Circle's CCTP, a system that burns USDC on the source chain and mints an equivalent amount on the destination chain according to reports. Critics say this centralization enables Circle to freeze assets but highlights concerns about accountability and response times according to analysis.

What Role Does Centralization Play in USDC's Governance?

The Drift Protocol case is the latest in a series of incidents where Circle has been criticized for its response times according to reports. ZachXBT noted that in the Drift case, over $232 million in USDC was reportedly moved from Solana to Ethereum via the CCTP in under six hours according to data. No action was taken by Circle during this window as reported.

Blockchain experts have long debated the risks and benefits of centralized stablecoin governance according to analysis. While centralization provides the ability to freeze assets, it also raises concerns about transparency and accountability according to reports. Critics argue that the current governance structure gives Circle excessive control without commensurate oversight according to analysis.

What Are the Regulatory Implications of These Criticisms?

Federal Reserve official Barr is advocating for stricter oversight of stablecoins, emphasizing the need for stronger capital requirements, tighter control over safe reserves, and improved anti-money laundering (AML) measures according to reports. The ongoing rulemaking process following the Genius Act will shape the regulatory landscape for stablecoins according to analysis.

Barr's position reflects a broader recognition of the risks associated with crypto and the need for systemic controls to prevent financial instability according to reports. The debate over how tightly regulators should define "safe assets" is particularly important, as it determines how flexible stablecoin issuers can be in their operations according to analysis.

How Is Circle Responding to These Challenges?

Circle went public in July 2025 through a traditional IPO, following the cancellation of a planned SPAC merger in 2022 according to reports. The company now provides stablecoin services and payment infrastructure to institutional and retail clients according to data.

Circle's public listing has increased scrutiny of its operations, including its response times to thefts according to analysis. The company has secured significant investment from major institutions such as Goldman Sachs and BlackRock according to reports.

Investor confidence in stablecoin governance will be crucial as regulatory frameworks evolve according to analysis. The controversy surrounding USDC's governance may influence how regulators define the responsibilities of stablecoin issuers in the future according to reports.
