Binance accused of sharing user data with Russia in Ukraine donation case
Cryptocurrency exchange Binance supplied Russian investigators with personal data and transaction records that later became key evidence in a terrorism‑financing case linked to donations to Ukraine, according to an investigation published on Aug. 17 by Reuters.
The documents cited in that investigation indicate that Binance transmitted identity information and detailed records of crypto transfers belonging to Russian IT specialist Yuri Belenkiy. The dataset reportedly included his home address, phone number, date of birth, passport details and information about his Bulgarian residence permit. Russian authorities are said to have incorporated these materials into the criminal case file as proof of his alleged offenses.
Belenkiy, 49, stands accused of sending the equivalent of more than 700 dollars in cryptocurrency to groups that Moscow claims are tied to Ukraine’s armed forces. He is currently in pre‑trial detention in Russia on terrorism‑financing charges. His defense lawyer and the Russian investigative bodies involved did not respond to questions about Binance’s reported role in the case.
According to internal documents reviewed in the Reuters probe, Russia’s Investigative Committee sent a formal request to Binance for the suspect’s transaction history. In response, the exchange allegedly produced a file confirming that Belenkiy had transferred funds to a crypto wallet promoted by exiled Russian journalist and Kremlin critic Arkady Babchenko.
Babchenko had previously published several wallet addresses while raising funds to buy medical equipment for Ukrainian soldiers. Russian investigators claim that Belenkiy made multiple payments to one of those addresses between January 2023 and March 2024, framing the donations as support for what Moscow characterizes as terrorist activity rather than humanitarian assistance.
In addition, the Investigative Committee accuses Belenkiy of sending cryptocurrency to a group associated with the Azov Brigade, a unit within Ukraine’s National Guard. Russia officially designates Azov as a terrorist organization, though that classification is not universally recognized by other countries. The alleged links to both Babchenko’s fundraising efforts and Azov‑related entities underpin the terrorism‑financing counts brought against him.
An interim case summary reportedly sent by investigators to the Russian prosecutor general’s office explicitly cites the Binance transaction records as part of the evidentiary basis for the charges. That case outline was later obtained by the First Department, a legal assistance group that supports defendants in politically sensitive prosecutions in Russia. The organization is said to have received the documents from one of Belenkiy’s relatives, though the news agency that reported on the case emphasized it could not independently verify the exact chain by which those files reached the group.
Binance, approached for comment, refused to discuss the confidential law enforcement request or Belenkiy’s situation specifically. The company instead issued a general statement about its policy of working with authorities around the world.
The exchange said that, like other large financial institutions, it responds to legally valid information demands from law enforcement agencies globally, subject to applicable privacy, data‑protection and regulatory constraints. Binance stressed that it neither writes national legislation nor decides which actions are criminalized and cannot control how governments ultimately deploy the information it provides in court proceedings. Those decisions, the firm said, lie entirely with state authorities.
Public guidance on Binance’s official resources instructs law enforcement bodies in Russia and Belarus to send requests to a designated email address. According to the Reuters account, Russian investigators received at least two responses from that contact in relation to Belenkiy’s case. The public instructions say the company supplies information and operational support when required by law, but do not clarify which specific Binance corporate entity processes Russian requests, which jurisdiction’s law governs each disclosure, or what internal criteria are applied when cases appear politically motivated.
This lack of clarity has become more pronounced because Binance announced in September 2023 that it would completely exit the Russian market. The company said it had agreed to sell its Russian operations to local exchange CommEX and that maintaining a presence in Russia was no longer compatible with its global compliance strategy. The official statement stressed that Binance would not retain any revenue‑sharing arrangement or option to repurchase the Russian business, and that a phased customer migration and shutdown of services would take up to twelve months.
Despite that declared exit, the new reporting suggests that Binance continued communicating with Russian investigators afterward. Moscow‑based lawyer Mike Bystrov argued that once Binance had left the Russian market, it was under no legal obligation to honor Russian law enforcement requests. In his view, the exchange could have declined to provide the records that later appeared in the terrorism‑financing case.
Binance rejected Bystrov’s reading but did not specify which particular legal framework either compelled or allowed it to disclose Belenkiy’s data. The company’s stance highlights a gray area facing multinational platforms: even after leaving a country, firms may still hold historical customer records on servers outside that jurisdiction while continuing to receive formal requests from that country’s authorities.
From a corporate standpoint, maintaining limited cooperation with law enforcement does not necessarily mean that a company has resumed full commercial operations in a territory. Businesses frequently preserve archived transaction histories for regulatory, tax and compliance reasons and may respond to legitimate legal demands even after halting services. However, the legal foundation and geographic limits of such cooperation have become central and contentious questions in Belenkiy’s case.
The Russian successor platform CommEX, which took over Binance’s local business, later ceased operations as well, adding further uncertainty over who ultimately holds responsibility for legacy Russian user data. The collapse of the intended transition has raised additional questions about how records were stored, who can access them, and which jurisdiction’s rules should apply, especially where human‑rights concerns intersect with financial surveillance.
Belenkiy’s personal status as a Russian citizen with a Bulgarian residency permit introduces another major unresolved issue: the potential reach of European Union data‑protection law. Lawyer Bystrov has argued that, because Belenkiy is legally resident in an EU member state, his personal information should be protected under the General Data Protection Regulation. If that interpretation holds, any transfer of his data to Russian authorities might be subject to strict limitations on cross‑border data flows and to requirements that such transfers not facilitate human‑rights abuses or politically driven prosecutions.
At present, it remains unclear whether European regulators have been informed of the alleged data transfer, whether any data‑protection authority has opened an inquiry, or whether Binance carried out a formal assessment of risks associated with sending information to Russia in a politically charged context. The unanswered GDPR questions go to the heart of a broader debate about how far crypto platforms must go to protect users when authoritarian or semi‑authoritarian states invoke counter‑terrorism laws.
The case also illustrates the tension between two competing expectations placed on global exchanges. On one side, governments and international watchdogs demand that platforms cooperate fully against money laundering, sanctions evasion and terrorism financing. On the other side, users and civil‑liberties advocates expect these same companies to resist abusive or politicized use of financial‑crime laws. When donations are made to causes tied to active conflicts-such as fundraising for Ukrainian forces-classifying them as legitimate aid or as terrorist support can become intensely political.
For Binance, the controversy lands at a time when the company has already been under heavy scrutiny from regulators in multiple jurisdictions and has faced enforcement actions over historical compliance failures. Its public commitment to strengthening anti‑money‑laundering controls and working more transparently with authorities may now collide with privacy expectations and human‑rights considerations, especially where Russia’s broad terrorism legislation is concerned.
The outcome of Belenkiy’s case could therefore set an important precedent for how crypto exchanges handle future requests from states engaged in geopolitical conflicts. If courts in Russia proceed largely on the basis of transaction records supplied by an offshore exchange, that may embolden other governments to rely more aggressively on similar cooperation in politically sensitive matters. Conversely, regulatory or legal pushback in the European Union or elsewhere over data transfers in such contexts could push exchanges to adopt stricter internal standards for evaluating requests.
For individual users, the episode is a reminder that so‑called pseudonymous blockchain transactions become fully identifiable once they are linked to real‑world KYC data held by centralized platforms. While some donors may believe they are simply contributing modest sums-such as the roughly 700 dollars at issue in this case-the combination of exchange records and expansive national security laws can turn modest humanitarian support into the basis for serious criminal allegations.
As the legal process against Belenkiy moves forward, several questions remain unresolved: whether European data‑protection bodies will assess the transfer of his personal information; whether Binance will provide more detail on the legal grounds for its cooperation; and how other exchanges will respond in similar cases involving political dissent or wartime donations. Until those issues are addressed, the intersection of crypto compliance, cross‑border data sharing and human‑rights risks will remain at the center of the global debate over the responsibilities of major trading platforms.
