Grinex sanctioned by U.S. authorities for acting as the successor to Garantex, a Russian crypto exchange linked to ransomware and illicit finance. The move cuts its access to the global financial system and places pressure on its leadership.
Why Grinex Was Targeted
The U.S. Treasury’s Office of Foreign Assets Control announced the sanctions in August 2025. Officials said Grinex inherited operations and customers from Garantex, which was sanctioned in 2022 for laundering more than $100 million in ransomware and darknet proceeds.
By classifying Grinex as a direct successor, regulators ensured it would face the same restrictions as Garantex. The sanctions prevent the exchange from engaging with U.S. financial institutions or accessing any services tied to the American market.
Executives and Partners Named
Sanctions also apply to several Grinex executives and affiliated companies in Russia and Kyrgyzstan. Authorities highlighted the role of the A7A5 stablecoin, pegged to the Russian ruble, in facilitating sanctions evasion and disguising illegal transfers.
Rewards for Information
The U.S. is offering up to six million dollars for information that leads to the capture of Garantex leaders. This includes a five million dollar reward for the co-founder and one million dollars for other senior officials involved in the network.
Impact on Crypto Crime
The Grinex sanctions strike at both the platform and the broader infrastructure supporting illicit cryptocurrency flows. This approach aims to disrupt ransomware payment channels and block attempts to rebrand under new names.
The move sends a clear warning to other platforms: facilitating illegal financial activity will trigger swift and severe consequences, regardless of rebranding or relocation.
Conclusion
Grinex sanctioned reflects a determined U.S. strategy to dismantle crypto networks enabling cybercrime. By targeting both the exchange and its leadership, authorities aim to cut off the channels that sustain ransomware and money laundering operations.
