T3 Crime Unit Freezes $450M in Illicit Crypto
A joint initiative backed by Tether, TRON, and TRM Labs says it has frozen more than $450 million tied to suspected crypto-related crime since launching in 2024.
The T3 Financial Crime Unit (T3 FCU), a collaborative anti-crime initiative supported by Tether, TRON, and blockchain intelligence firm TRM Labs, has frozen over $450 million in illicit digital assets since its launch in September 2024, according to a statement released on May 14.
The group said it has significantly expanded its enforcement capabilities over the past year, working alongside authorities in 23 jurisdictions worldwide, including the United States, Spain, Germany, the Netherlands, and Bulgaria. The initiative focuses on identifying suspicious blockchain activity and coordinating rapid responses with law enforcement agencies.
According to the statement, T3 FCU recorded a 43.9% increase in intercepted illicit proceeds in 2025 compared with the previous year, reflecting what the organization described as growing operational efficiency and stronger global coordination.
Rapid Response to Crypto Crime
T3 FCU said its infrastructure allows investigators to identify suspicious transactions and freeze assets within 24 hours of receiving requests from authorities. The unit noted that this rapid response capability has been used during account takeover incidents and violent crime cases involving kidnappings, extortion, and home invasions.
The initiative also stated that it has supported investigations tied to:
- Exchange hacks
- DPRK-linked activity
- Terrorist financing
- Wrench attacks and extortion schemes
The group described itself as a bridge between blockchain companies and global law enforcement agencies, aiming to reduce criminal activity while supporting broader adoption of digital assets.
“We take pride in working with regulators and institutions to make blockchain technology more reliable and trustworthy,” said Tether CEO Paolo Ardoino.
“This $450 million milestone is just the beginning of what T3 is capable of, as its impact will only continue to grow in scale and importance.”
The statement also noted that the Financial Action Task Force (FATF) earlier this year referred to T3 FCU as an “invaluable resource for law enforcement agencies worldwide.”
Operation Lusocoin Among Major Cases
One of the most significant investigations linked to the unit was Operation Lusocoin, a Brazilian Federal Police operation targeting a large criminal network.
According to the announcement, the investigation led to the freezing of more than 3 billion Brazilian reals ($598.9 million) in assets, including 4.3 million USDT allegedly connected to illicit activities.
The case highlights the increasing role stablecoin issuers and blockchain analytics firms are playing in international enforcement operations, particularly as regulators intensify scrutiny of crypto-related financial crime.
Illicit Crypto Activity Still Rising
The update from T3 FCU comes amid broader concerns about the scale of illicit activity across the digital asset sector.
Data from TRM Labs showed that illicit actors captured approximately 2.7% of available crypto liquidity in 2025, a slight decline from 2.9% in 2024. However, the analytics firm reported that the overall volume of illicit crypto transactions surged to a record $158 billion last year, marking a nearly 145% increase compared with the prior period.
The figures suggest that while enforcement efforts may be improving, the size and sophistication of criminal operations within the crypto ecosystem continue to expand.
USDT Freezes Continue to Grow
The latest T3 FCU milestone follows separate data published by blockchain security firm BlockSec on May 8.
According to BlockSec’s USDT Freeze Tracker, more than $500 million in USDT across the Ethereum and TRON networks was frozen over the previous 30 days. The data underscores Tether’s increasingly active role in enforcement actions tied to suspicious blockchain activity.
T3 FCU described its model as a “first-of-its-kind” public-private partnership designed to combat financial crime while maintaining support for blockchain innovation. Since launching in 2024, the initiative said it has built rapid-response capabilities across five continents and continues to expand cooperation with regulators and investigative agencies globally.
As crypto adoption grows worldwide, industry-led enforcement partnerships like T3 FCU are becoming an increasingly important part of the digital asset ecosystem. The initiative’s latest figures highlight how blockchain companies are moving beyond infrastructure development and taking a more active role in policing illicit activity across the sector.
