Overview

• The State Department’s Transnational Organized Crime Rewards Program is offering up to $5 million for information on Aleksandr Mira Serda and $1 million for other key Garantex figures
• The Treasury’s Office of Foreign Assets Control re-designated Garantex and designated its alleged successor Grinex, three executives including Sergey Mendeleev and Pavel Karavatsky, and six partner firms such as InDeFi Bank and Exved
• Sanctions block all US-linked assets of the designated entities, bar US persons from transacting with them, and warn non-US firms they risk secondary penalties for providing support
• US law enforcement says Garantex processed at least $96 billion in crypto transactions tied to hacking, ransomware, terrorism financing and darknet markets between 2019 and March 2025
• These actions build on a March operation that seized Garantex domains, froze over $26 million in cryptocurrency, and led to indictments and arrests abroad as investigations continue
