Circle Under Scrutiny: The Controversial Freeze Powers of USDC
preferred on
Circle, the issuer of the USDC stablecoin, faces mounting criticism over its approach to freezing wallets, particularly in instances related to alleged illicit activities. The company’s policy has resulted in inconsistencies that are raising questions among users and the broader crypto community.
An Unequal Application of Freeze Powers
ZachXBT’s “Circle Files” reveal a troubling pattern; Circle has been slow to freeze wallets associated with thefts amounting to over $420 million since 2022. In contrast, the firm acted quickly to freeze 16 operational wallets connected to a sealed US civil case. This raised eyebrows as the wallets were linked to legitimate businesses like exchanges and casinos that did not appear connected to any illegal activity.
Why This Is Important:
USDC serves as a core dollar infrastructure for exchanges, payments, and decentralized finance (DeFi). The ability of Circle to freeze wallets in a seemingly arbitrary manner poses significant risks for businesses that rely on predictability in their operations.
The controversy escalated when Circle unfroze at least one wallet—belonging to Goated.com—following the scrutiny. This added to the skepticism regarding how carefully Circle evaluates the addresses it blocklists. The timing of Circle’s actions—swift in civil matters yet slow with hacking incidents—raises critical questions about its governance.
The Scale and Impact of USDC
As of April 2023, USDC had approximately $77.2 billion in circulation, occupying approximately 24.5% of the nearly $316.8 billion stablecoin market. During the Drift exploit episode, over $280 million in USDC was transferred across 100+ transactions in a matter of hours. This scale underscores the urgency of understanding the gap between Circle’s stated capabilities and practical outcomes.
Circle’s Governance Structure
Circle’s architecture features a blocklist function within its EVM stablecoin contract, allowing it to restrict certain addresses from transferring or receiving tokens. With the added ability to pause or upgrade contracts, Circle’s governance structure carries real enforcement strength.
Key Policies:
EVM Stablecoin Contract:
- Prevents blocklisted addresses from engaging on-chain.
Access Denial Policy:
- Allows Circle to block addresses under specific conditions, such as legal directives or security threats.
- USDC Terms:
- Gives Circle wide latitude to freeze balances tied to perceived illegal activity, without the obligation to verify or track user activities.
This regulatory flexibility stands in stark contrast to its purported commitment to a transparent and accountable system.
Critiques and Their Implications
The 16-wallet incident exemplifies the inconsistent application of Circle’s freeze powers. While businesses faced immediate freezing actions tied to civil matters, alleged theft cases faced negligible response. The Drift incident is particularly noteworthy as it showcases how real-time on-chain activity can be overlooked.
Following the introduction of the GENIUS Act in July 2025, which established regulatory frameworks for payment stablecoins like USDC, scrutiny of Circle’s practices intensified. The act is seen as essential in aligning crypto regulations with financial expectations, especially in light of the FATF’s recommendations for quicker public-private coordination in asset recovery.
Future Paths for Circle
Bull Path: Towards Transparency
If Circle bolsters its internal review process for freezes and improves its response time during theft incidents, the controversy might pave the way for improved governance. Under the GENIUS framework, Circle might emerge as a more credible and stable issuer, possibly recovering USDC’s market share to between 25% and 27%.
Bear Path: Risk of Diversification
Conversely, if incidents of slow responses or overreaching civil authority freezes continue, operators may begin to disperse their holdings away from USDC to other stablecoins, which could pull USDC’s market share down to 20% to 23%.
Ultimately, the next real test for Circle will come during future crisis scenarios. Speedy resolutions for freeze incidents could signal a shift towards effective governance. Failure to meet user expectations may lead to a gradual distancing from USDC by enterprises wary of its inherent operational risks.
