The U.S. has expanded sanctions on Russian crypto exchange Garantex and its successor Grinex, citing over $100 million in illicit transactions tied to ransomware groups and darknet markets. The Treasury and Justice Departments highlighted its role in laundering funds for Conti, LockBit, and others. Despite earlier asset seizures and domain takedowns, Garantex rebranded as Grinex. To intensify efforts, the State Department announced a $6 million bounty—$5 million for information on co-founder Aleksandr Mira Serda and $1 million for other leaders—aiming to disrupt Russian-linked crypto crime networks and incentivize intelligence that leads to arrests or convictions.
