Philosophical Clash Between Circle and Tether Over Freezing Stolen Assets: Challenges Left by the Drift Protocol Incident

In April 2026, a clear line was drawn between the two giants of the stablecoin market, Circle and Tether. While Tether boasted of its achievements by cooperating with U.S. law enforcement to freeze $344 million in assets, Circle faced a class-action lawsuit for refusing to freeze $285 million in funds from the Drift Protocol hack. This incident raises fundamental questions about whether stablecoin issuers are mere technology providers or should act as sheriffs of digital finance.

When a clear connection to sanctioned entities or criminal networks is confirmed, we act immediately and decisively.

Tether's record-breaking freeze on April 14, 2026, stands in stark contrast to Circle's silence. Despite a significant portion of the funds drained from Drift Protocol being converted into USDC, Circle's refusal to intervene has turned the philosophical debate over asset freezing into a legal and regulatory storm. Tether CEO Paolo Ardoino emphasized that such proactive responses are a key factor in enhancing Tether's credibility.

The Drift Protocol Hack and the Whereabouts of $230 Million

The Drift Protocol hack, which triggered this situation, resulted in the theft of approximately $285 million in assets. About $230 million of this was quickly converted into USDC, causing Drift's Total Value Locked (TVL) to plummet from $550 million to less than $250 million. The price of Drift's governance token, a Solana-based decentralized exchange, also crashed 77% from its all-time high, inflicting massive losses on investors.

• Total assets drained: Approx. $285 million
• Amount converted to USDC: Approx. $230 million
• Drift Protocol TVL change: Plummeted from $550 million to less than $250 million
• DRIFT token price: Crashed 77% from its all-time high

Circle adheres to the principle of not freezing assets without an explicit order from a U.S. court. Circle CEO Jeremy Allaire made it clear at a New York conference on March 15, 2025, that Circle would not act as a 'digital sheriff' based on its own judgment. This reflects the company's philosophy of prioritizing judicial due process and its wariness of undermining decentralized values through indiscriminate asset freezes.

Dante Disparte, Circle's Chief Strategy Officer, also emphasized that the power to freeze assets is a compliance obligation exercised only when legally mandated. He reaffirmed that while Circle has frozen wallets in the past, it has always been based on legal grounds, and the company avoids arbitrary asset control. This stance is based on the logic that private companies should not act as judicial authorities unless directly ordered by regulators.

Tether's Proactive Response and Regulatory Differentiation

On the other hand, Tether has implemented a voluntary wallet-freezing policy linked to the Office of Foreign Assets Control (OFAC) sanctions list since December 2023. To date, approximately $1 billion worth of USDT has been returned to crime victims and law enforcement agencies, and this active cooperation is emerging as a commercial differentiator for Tether in an intensifying regulatory environment. Treasury Secretary Scott Bessent evaluated Tether's $344 million freeze as an achievement aligned with government efforts to block Iranian-linked financial networks.

The class-action lawsuit filed against Circle in the Massachusetts Federal Court argues that Circle failed to exercise the 'sole discretion' specified in its terms of service. The plaintiffs pointed out that despite the clear criminal origin of the funds, Circle's failure to exercise its power to block addresses caused significant harm to investors. This is forming a legal issue over whether the technical control held by Circle is not just a right but an obligation to prevent damage.

This debate is acting as a catalyst to pressure the passage of the GENIUS and CLARITY acts in the U.S. A FATF report released in March 2026 emphasized that blockchain analysis and control measures must produce substantial enforcement results. With the Office of the Comptroller of the Currency (OCC) implementation proposal deadline approaching on May 1, regulatory pressure is expected to intensify. Regulators expect stablecoin issuers to play a more active role in anti-money laundering and asset recovery processes.

The question "What happens now?" raised by American Banker poses a heavy challenge to the entire stablecoin industry. Whether Circle's neutrality, which emphasizes due process, can survive the dual pressure of class-action lawsuits and federal government scrutiny will be a key variable determining the future direction of the market. Ultimately, stablecoin issuers are likely to be forced to make clearer choices between the two values of security and neutrality.
