Binance provided Russian authorities with personal and transaction data on a Russian IT specialist whose cryptocurrency donations to Ukrainian fundraising campaigns were later used as evidence in a âterrorismâ financing case, Reuters reported on Monday.
The documents reviewed by Reuters show that Russian investigators requested the information from Binance and received details identifying the user and his cryptocurrency transfers to Ukrainian organizations. JOIN US ON TELEGRAM Follow our coverage of the war on the @Kyivpost_official.
The case raises questions about Binanceâs handling of Russian law enforcement requests after the company said in 2023 that it had fully exited the Russian market. Binance data used in Russian criminal case Russian investigators alleged in October 2025 that IT specialist Yuri Belenkiy, a 49-year-old Russian citizen with a Bulgarian residency permit, had sent more than $700 in cryptocurrency to the Ukrainian military and an associated organization.
Belenkiy was detained in September 2025 and is currently in a Russian jail awaiting trial on terrorism financing charges. According to the documents reviewed by Reuters, Russian law enforcement asked Binance for Belenkiyâs transaction history. The exchange subsequently provided information showing transfers to Ukrainian organizations.
The data was incorporated into the case against Belenkiy. An interim case summary sent to Russiaâs Prosecutor Generalâs Office cited the cryptocurrency transfers as grounds for the so-called âterrorismâ financing charges.

Binance says it complied with legal requests Binance disputed the suggestion that it had improperly handed over the information. âBinance does not make or enforce the laws of any jurisdiction, determine charges, or decide how any government uses information in legal proceedings,â a company spokesperson told Reuters.
The exchange said it cooperates with lawful requests from law enforcement agencies worldwide, subject to applicable legal, privacy, and regulatory requirements. Binance declined to comment specifically on Belenkiyâs case, saying it does not discuss confidential law enforcement requests or individual cases.
The company said in September 2023 that it was fully exiting Russia because operating there was incompatible with its compliance strategy. It said the exit involved no ongoing revenue sharing and no option to buy back the business. Questions over EU data protection rules The disclosure could also raise questions under European data protection law if Belenkiy was registered with Binance as an EU resident.
Mike Bystrov, a lawyer specializing in cryptocurrency regulation, told Reuters that an EU resident would generally be covered by the blocâs General Data Protection Regulation (GDPR). He said GDPR rules could restrict the transfer of personal data to Russia and that disclosure could require a court order and compliance with strict conditions.
However, Reuters could not establish whether Belenkiy was registered with Binance as a Bulgarian resident. Binance did not comment on whether the disclosure in Belenkiyâs case violated GDPR rules and Bulgariaâs Commission for Personal Data Protection did not respond to Reutersâ questions about the case.
Russia has targeted crypto donations to Ukraine Russian authorities have prosecuted a number of people who donated cryptocurrency to Ukrainian causes, according to rights activists tracking such cases. The documents reviewed by Reuters indicate that investigators also asked Binance to identify other people who had transferred cryptocurrency to a wallet used to solicit donations for Ukraine.
The outcome of that request is unclear. The fundraising campaign was promoted by Arkady Babchenko, a Russian journalist and Kremlin critic living in exile. In posts on Telegram, he listed cryptocurrency wallets for donations that he said would be used to purchase medical equipment for Ukrainian soldiers.
Babchenko told Reuters that he had warned people inside Russia against donating to Ukrainian military fundraisers because of the risk of arrest. He described the sharing of Russian donorsâ information with Russian authorities as inappropriate. The First Department, a Russian rights organization that obtained the law enforcement documents from a relative of Belenkiy, said the case illustrated the risks faced by Russians supporting Ukraine through cryptocurrency.
Reuters said it could not independently establish whether Binance had provided Russian authorities with information about other users who made similar donations.
