Tether’s jointly established T3 Financial Crime Unit, formed with TRON and blockchain analytics firm TRM Labs, has announced it froze more than 450 million USDT on suspicions of criminal activity since September 2024. According to unit figures, the USDT freezing actions targeted assets linked to global money laundering schemes, cryptocurrency exchange attacks, North Korea-associated cybercrimes, illicit organization financing, drug trafficking, kidnapping, and extortion as part of sweeping, international investigations.
Global operations and rapid response
Operating in close coordination with law enforcement across five continents—including agencies in the US, Spain, Germany, the Netherlands, and Bulgaria—the T3 unit reports major advances. In 2025, the group saw a 43.9% rise in recovered assets tied to illegal activities versus the previous year. The team says it can initiate digital asset freezes within 24 hours upon request, far outpacing traditional financial institutions’ responsiveness.
Among the highlighted cases is the freezing of approximately 26.4 million USDT thought to belong to a Europe-based money laundering ring, jointly executed with Spain’s Guardia Civil in early 2025. In another major action dubbed “Operation Lusocoin,” Brazil’s Federal Police traced and immobilized 4.3 million USDT tied to a crime syndicate.
The assets frozen also include wallets linked to North Korean cybercrime groups and nearly 9 million dollars associated with the Bybit exchange hack. In April 2026, the biggest single operation so far took place, when 344 million USDT were frozen on the TRON network.
Recognition and regulatory pressure
The Financial Action Task Force (FATF) praised the T3 Financial Crime Unit at the start of 2025, calling it “an essential resource” for global law enforcement and highlighting TRM Labs’ Beacon Network as a standout example of public-private partnership.
According to TRM Labs, blockchain-based criminal activity hit a total of 158 billion dollars in 2025, a surge that has intensified regulatory scrutiny on the crypto sector. As a result, stablecoin issuers and blockchain platforms have been forced to ramp up compliance procedures and oversight to meet regulators’ standards.
“Compliance isn’t optional—it’s our commitment to protecting users and preventing crime,” said Tether CEO Paolo Ardoino, adding that the 450 million dollar threshold demonstrates only the initial capacity of the T3 unit.
Chris Janczewski, a former IRS special agent and now T3 advisor, emphasized the significance of the new approach: “Combining real-time intelligence with public-private partnerships has made it possible to instantly disrupt criminal operations.”
Centralization debate in the blockchain sphere
The recent scale of asset freezes has reignited discussion within the blockchain community about the extent of control centralized stablecoin issuers retain. Unlike decentralized models such as Bitcoin, these issuers can blacklist specific wallets and freeze funds at the issuance level, challenging core decentralization principles.
On-chain analytics from BlockSec show that over 500 million USDT were frozen in just the past month—a figure surpassing T3’s own disclosures and confirming that Tether actively blacklists addresses across multiple blockchains.
