The T3 Financial Crime Unit (T3 FCU), established through a partnership between Tether, Tron, and TRM Labs, announced that it has frozen over $450 million in funds linked to criminal activity since its inception in 2024. The group works in close cooperation with law enforcement agencies across 23 jurisdictions to combat crimes such as drug trafficking, exchange hacks, terrorism financing, and extortion. This is reported by Cointelegraph.com .
T3 FCU primarily focuses on transactions involving USDT stablecoins on the Tron blockchain. According to the organization, the detection rate for illicitly obtained funds in 2025 increased by 43.9% compared to the previous year. TRM Labs analysis indicates that illicit transfers via crypto-assets reached a record $158 billion in 2025.
The Financial Action Task Force (FATF) has assessed the T3 FCU's activities as a vital resource for law enforcement agencies. Nevertheless, some members of the crypto community have expressed concerns that these centralized freezing mechanisms could undermine the permissionless and decentralized nature of the blockchain.
The Tron network, describing itself as a neutral technology provider, stated that it cannot directly control transactions and that the responsibility for identifying and stopping illicit activity lies with Tether and its partner organizations. Meanwhile, according to security firm BlockSec, over $500 million in USDT has been frozen in the last 30 days.
