Russia has officially blacklisted crypto exchange WhiteBIT, labeling it an “undesirable organization” over alleged support for Ukraine’s military as the war enters its fourth year.

The Russian Prosecutor General’s Office said the designation bans WhiteBIT and its parent company, W Group, from operating in the country, including holding bank accounts, moving funds, or serving Russian clients.

Authorities claim the Lithuania-based exchange, originally founded in Kharkiv, Ukraine, helped users move money out of Russia through “gray schemes” and was involved in other unspecified illegal activities. They also allege WhiteBIT has supported Ukraine’s military efforts since 2022 and cooperated with institutions linked to the Ukrainian government.

Prosecutors further accused WhiteBIT’s leadership of donating $11 million to Ukraine in 2022, including roughly $900,000 allegedly allocated for drone purchases. They also tied the exchange to United24, a crypto donation initiative launched by Ukrainian President Volodymyr Zelenskyy that funds areas such as medical aid and education.

WhiteBIT had already barred Russian users under its AML and sanctions compliance policies, citing adherence to EU restrictions imposed on Russia.

The move comes amid broader financial pressure linked to the war. Ukraine has sanctioned multiple Russian crypto-related firms, while blockchain analytics reports have suggested Russia has used digital assets to обход sanctions and move funds internationally.
