Spanish law enforcement has teamed up with blockchain firms Tron, Tether and TRM Labs to freeze $26.40 million cryptocurrency linked to a pan-European money laundering operation. The operation is in partnership with the T3 Financial Crimes Unit, an anti-crime initiative launched by three blockchain companies in August 2024. The investigation relies on police surveillance to identify criminal organizations. Its crypto wallets have been linked to illegal activities, using "KYC" data from service providers, the T3 unit's largest coordinated freeze to date, adding to the $126 million recorded in its first year of existence. Tron's security measures have reportedly reduced illegal transactions on its blockchain by $6 billion. TRM Labs found that 49% of Tron's illegal activities were related to sanctioned entities and 32% were related to blacklisted funds.
