In a sweeping move against crypto-related crime, Tether, Tron, and TRM Labs’ joint venture, the T3 Financial Crime Unit, has ramped up its global fight against illicit activities linked to cryptocurrencies since the start of 2024. Coordinating with law enforcement in 23 jurisdictions worldwide, the team has directly targeted offenses ranging from illegal drug trafficking and exchange hacks to North Korea-linked flows, terrorist financing, violent ransom plots, and kidnappings.
Next-generation push against crypto crime
At the heart of the T3 Financial Crime Unit’s operations is the monitoring of USDT, Tether’s stablecoin, on the Tron blockchain. According to the unit, they can freeze assets within 24 hours at the request of authorities, enabling swift intervention in emergency scenarios. In 2025, their success rate in capturing illicit funds rose by an impressive 43.9% over the previous year.
TRM Labs highlighted that total illicit crypto flows soared to a record $158 billion in 2025. This unprecedented volume puts renewed pressure on stablecoin issuers and blockchain networks to comply with regulations and extend deeper cooperation with law enforcement agencies.
Controversy over asset freeze tactics
Fresh on-chain data from blockchain security firm BlockSec confirms that more than $500 million in USDT was frozen over a 30-day period. The scale and approach of Tether’s blacklisting and asset-freezing actions have sparked heated debate within the crypto sector regarding transparency and methodology.
There were no clear answers from Tether when asked how the $450 million in frozen assets tied to T3 Financial Crime Unit investigations align with the company’s broader asset-freezing policies, or exactly how much of that amount was native to Tron-based USDT. As Tether expands its compliance and freezing capabilities, the company continues to face scrutiny over the growing centralization of its operations.
Tron emphasized in a statement that they are “a neutral technology provider,” noting that it is not possible for them to directly monitor every user or transaction. They stressed the importance of joint efforts with Tether, TRM Labs, and law enforcement to identify and prevent malicious activity.
Global impact and evolving legal landscape
In 2024, the Financial Action Task Force (FATF) cited the T3 Financial Crime Unit as a “valuable resource” for law enforcement, recognizing its effectiveness in several FATF reports as a model for public and private sector collaboration.
European authorities reported losses reaching $101 million from crypto-related violence and threats, as regulators and security agencies closely track such collaborative anti-crime mechanisms in the sector.
Tron, a major platform in the crypto ecosystem, is renowned for offering low-cost stablecoin transfers. However, this advantage can also make it easier for illicit actors to exploit the network for criminal purposes, prompting companies to seek a balance between the open nature of blockchain technology and the need for robust security tools.
The evolving landscape underscores the tension within the crypto world between user privacy, decentralized technology, and regulatory oversight. As companies in the sector respond to growing pressure from authorities, the role of dedicated financial crime units is likely to expand further.
Ultimately, the high volume of frozen assets this year highlights both the industry’s response to global regulatory scrutiny and the persistent challenge of targeting illicit funds moving through digital assets. Cooperation among platforms, law enforcement, and security firms remains crucial to tackling crime without undermining the foundational principles of blockchain.
With surging crime-related flows driving regulatory responses, the industry faces ongoing debates over transparency, due process, and the implications of centralized measures in decentralized financial systems.
