Key Takeaways:
Tether froze $344 million in USDT on April 23, 2026, in coordination with OFAC and U.S. law enforcement. Tether has supported over 2,300 global cases, freezing $4.4 billion in assets, including $2.1 billion tied to U.S. agencies. CEO Paolo Ardoino signaled Tether will continue real-time monitoring and direct law enforcement coordination going forward.
Tether Blocks $344M in Stablecoin Funds Linked to Sanctions Evasion and Criminal Networks
The stablecoin issuer said on Thursday that the freeze was executed after investigators identified the wallets and flagged them for sanctions evasion, criminal network activity, or other illicit use. Tether moved to restrict the assets before the funds could be transferred further.
The action was coordinated with the Office of Foreign Assets Control and multiple U.S. law enforcement agencies. Tether said it follows OFAC guidelines on the Specially Designated Nationals List and holds a zero-tolerance policy on criminal use of its products.
Tether CEO Paolo Ardoino addressed the action directly. “ USDT is not a safe haven for illicit activity,” Ardoino said. “When credible links to sanctioned entities or criminal networks are identified, we act immediately and decisively.”
Ardoino pointed to public blockchain infrastructure as a core enforcement tool. Transactions can be followed, wallets can be flagged, and assets can be frozen before funds move again. That visibility gives investigators something traditional cash cannot offer.
Tether said it currently works with more than 340 law enforcement agencies across 65 countries. That cooperation has contributed to more than 2,300 cases globally, including over 1,200 connected to U.S. law enforcement.
Combined, those cases have resulted in the freezing of more than $4.4 billion in assets, with over $2.1 billion linked directly to U.S. authorities.
The April 23 freeze fits a broader pattern of coordination between Tether and federal investigators. The U.S. Department of Justice previously acknowledged Tether’s support in two separate enforcement actions involving pig butchering fraud, which resulted in seizures of nearly $61 million and approximately $225 million, respectively.
Tether said its model centers on real-time monitoring and direct coordination with investigators during active cases. The company described that approach as different from platforms that respond only after funds have already been dispersed.
Ardoino said platforms that fail to act quickly expose users, erode trust, and allow enforcement to break down. Tether’s response to the April action reflects its stated position that the company bears responsibility as one of the largest stablecoin issuers operating in the market.
The freeze adds to a growing record of blockchain-based law enforcement actions carried out with issuer cooperation. Moreover, the news follows the recent KelpDAO hack and Drift Protocol breach. Digital assets on public networks have proven traceable and recoverable when issuers and agencies coordinate in real time.
