Grinex Ceases Operations, Potentially Delivering a Heavy Blow to Russia’s Sanctions-Evasion Shadow Financial System
According to DL News, Russian cryptocurrency exchange Grinex announced last Wednesday that it would cease operations after suffering a cyberattack that resulted in the theft of over 1 billion rubles—approximately $13 million.
The report states that Grinex had processed nearly $100 billion in trading volume for the sanctioned stablecoin A7A5 in 2025. Its shutdown is expected to weaken Russian companies’ ability to convert rubles into usable international currencies and deliver a severe blow to Russia’s shadow financial system designed to circumvent sanctions. Grinex was viewed as the successor to Garantex, which had previously been sanctioned and shut down. Both Grinex and Old Vector—the issuer of A7A5—were sanctioned in August 2025 by the United States, the European Union, and the United Kingdom.
