T3 FCU was launched in September 2024. It is a public-private initiative aimed at detecting, tracking, and stopping illegal activities using cryptocurrencies.
This milestone highlights the growing role of coordinated blockchain oversight in tackling financial crime. It also strengthens trust across the digital asset ecosystem. Let’s take a closer look at Tether’s T3 FCU.
Practicing global collaboration
Since its inception, T3 FCU has supported law enforcement agencies across 23 jurisdictions in cases involving money laundering, fraud, hacking, terrorist financing, and organized crime. A notable example is our cooperation with the Brazilian Federal Police in Operation Lusocoin. Large-scale money laundering and currency evasion through cryptocurrencies was targeted. The operation resulted in the freezing of over R$3 billion in assets related to the criminal group, including USDT4.3 million. This shows that combining blockchain analysis and law enforcement expertise is effective.
The countries that recorded the most aid were the United States, Spain, Germany, Albania, Brazil, Australia, Poland, and the United Kingdom. Common investigations include crimes related to illegal goods and services, fraud, and prohibited substances. The force has also observed an increase in “wrench attacks,” incidents of violent coercion related to cryptocurrencies, highlighting the need for timely international intervention.

TRON founder Justin Sun said the $300 million milestone proves that progress happens when cross-sector partnerships work in sync. Esteban Castaño from TRM Labs stressed the importance of a shared, real-time approach to investigations, adding that no single organization can fight financial crime alone.
