Key Highlights
- Reuters reported that Binance provided Russian investigators with customer data linked to a Ukraine-related donation case.
- The information was reportedly used in a terrorism-financing case against Russian IT specialist Yuri Belenkiy.
- Binance said it cooperates with lawful law-enforcement requests while following applicable privacy and regulatory requirements.
- The cases highlight both the investigative value of exchange-held KYC data and the privacy questions that arise when customer information is shared across jurisdictions.
The role of cryptocurrency exchanges in law-enforcement investigations has come under renewed attention after a Reuters report said Binance provided Russian authorities with customer information connected to a Ukraine-related donation case.
As per a report from Reuters, Russian investigators obtained transaction records and personal information belonging to Yuri Belenkiy, a 49-year-old Russian IT specialist and Bulgarian resident who is being held in Russia awaiting trial.
Investigators allege that Belenkiy sent more than $700 in cryptocurrency to organizations connected to Ukraine’s military between January 2023 and March 2024. The transactions were later cited as evidence in terrorism-financing charges against him.
The report was based on law-enforcement documents reviewed by Reuters. The documents were reportedly obtained by The First Department, a Russian legal support organization. Reuters said it could not independently confirm how the documents were obtained.
How Binance data entered the case
The reported case illustrates the role centralized exchanges can play in connecting blockchain activity with an identified individual. According to the documents reviewed by Reuters, Russian investigators requested Belenkiy’s transaction history from Binance. The information reportedly included his date of birth, address, telephone number, and passport details. Binance also provided copies of his Russian passport and Bulgarian residency permit.
The transaction records were later incorporated into the evidence gathered against Belenkiy. An interim outline of the case sent to Russia’s prosecutor-general cited the cryptocurrency transfers as grounds for the terrorism-financing allegations.
Binance said it cooperates with lawful requests from law-enforcement agencies globally, subject to applicable legal, privacy, and regulatory requirements. The exchange also said it does not determine criminal charges or decide how authorities use information in legal proceedings. Binance declined to comment on Belenkiy’s individual case.
The distinction is important: the Reuters report describes Binance responding to a law-enforcement request, rather than establishing a formal partnership between Binance and Russian authorities.
Donations linked to Ukraine
The transactions were linked to fundraising efforts promoted by Arkady Babchenko, an exiled Russian journalist and Kremlin critic who supports Ukraine. Reuters stated that it reviewed posts from Babchenko’s Telegram channel listing cryptocurrency wallet addresses for donations. The funds were intended to help purchase medical equipment for Ukrainian soldiers.
Babchenko later told Reuters that he had warned people inside Russia against making such donations because of the risk of arrest. He also criticized the sharing of Russian donors’ information with law enforcement.
Russian investigators asked Binance to identify other users who had transferred cryptocurrency to the same wallet. The documents reviewed by Reuters did not establish whether those requests led to further arrests or prosecutions.
Rights activists tracking political cases in Russia say several dozen people have faced prosecution or conviction over donations to causes Moscow has classified as extremist or terrorist. Reuters could not independently verify the exact number.
Binance’s Russia exit
The disclosure is notable because Binance announced that it had completely withdrawn from Russia in 2023. Following Russia’s full-scale invasion of Ukraine in February 2022 and the Western sanctions imposed on Moscow, Binance moved to sell its Russian business. In September 2023, the exchange said it had fully exited Russia, with no ongoing revenue-sharing arrangement and no option to repurchase the business.
Despite the exit, the documents reviewed by Reuters show that Russian investigators were reportedly able to contact Binance through case@binanceholdings.ru, an email address the exchange had previously advised Russian and Belarusian law-enforcement agencies to use.
Investigators reportedly sent a request through the channel and received two replies containing information about Belenkiy’s transactions. The episode highlights how exchanges can continue to receive law-enforcement requests concerning past customer activity even after withdrawing from a particular market.
The episode illustrates a broader issue for global exchanges: leaving a market does not necessarily end their exposure to law-enforcement requests concerning historical customer activity or transactions conducted while the exchange served customers in that jurisdiction.
Broader exchange role
The development comes amid a wider pattern of authorities seeking customer information from centralized exchanges during investigations.
In another investigation, Argentine authorities ordered several cryptocurrency exchanges to provide information that could help identify wallet holders linked to the $LIBRA case. The requested information included KYC records and transaction histories.
In India, Binance assisted authorities investigating a ₹226 crore crypto network linked by investigators to alleged terror financing, with exchange data forming part of the broader investigation. The Crypto Times reported on the exchange’s role in the probe.
In Singapore, police have also worked with crypto exchanges to prevent suspected scam losses. An April operation involving exchanges helped authorities prevent more than $2.86 million in potential losses through targeted interventions.
The cases show that exchange–law-enforcement cooperation can range from responding to formal data requests to sharing information during active investigations or intervening to prevent suspected fraud.
While blockchain transactions can often be traced publicly, centralized exchanges may hold the KYC and transaction records needed to connect a wallet with a real-world identity. The extent and legal basis for that cooperation, however, can vary by jurisdiction and case.
Privacy questions remain
Belenkiy’s Bulgarian residency adds a separate privacy dimension to the case. Mike Bystrov of Stellar Consulting stated that Belenkiy could potentially have been covered by the European Union’s General Data Protection Regulation if his Binance account was registered as an EU customer. However, it could not be clearly established whether that was the case.
Bystrov said transferring personal information to Russia could face strict requirements under EU data-protection rules. Binance did not comment on whether the disclosure breached GDPR requirements.
The European Data Protection Board declined to comment on the individual case, saying enforcement of data-protection rules falls to relevant authorities in individual EU countries.
Those questions are separate from whether exchanges can lawfully cooperate with investigators. The relevant legal framework can depend on the customer’s status, the jurisdiction involved, the nature of the request and the legal basis for transferring the information.
Belenkiy remains in custody awaiting trial. Reuters could not determine whether other customers involved in Ukraine-related donations were identified or prosecuted.
The bottom line
The Binance case highlights one side of an increasingly important relationship between centralized crypto exchanges and law enforcement: exchanges can hold e KYC and transaction information needed to connect blockchain activity with identified customers.
At the same time, the Binance-Russia case shows why cross-border data sharing can raise separate privacy and due-process questions. Cooperation with law enforcement does not by itself establish wrongdoing by an exchange, and the legality of a particular disclosure depends on the applicable legal authority and jurisdiction.
For crypto users, the broader takeaway is that centralized exchanges are not merely trading venues. Their KYC systems and transaction records can become part of law-enforcement investigations, while their cooperation with authorities can also be used to prevent fraud and protect victims.
