Binance Data Linked to Ukrainian Donation Case
Binance reportedly provided Russian authorities with personal and transaction information belonging to Yuri Belenkiy, a Russian IT specialist accused of financing terrorism through cryptocurrency donations to Ukrainian organizations.
According to Reuters, Russian investigators used Binance records to identify Belenkiy as the source of more than $700 in cryptocurrency transfers. The information reportedly included his date of birth, address, phone number and passport details, along with copies of identification documents. Reuters report
Belenkiy was detained in September 2025 and remains in custody awaiting trial.
Russian investigators allege that he made the cryptocurrency transfers between January 2023 and March 2024 after an appeal from exiled Kremlin critic Arkady Babchenko. The funds were reportedly intended to support Ukraine’s military and a group associated with the Azov Brigade, which Russia has designated as a terrorist organization.
Binance Responded to Russian Law Enforcement Requests
Russian investigators reportedly contacted Binance to obtain Belenkiy’s transaction history.
The exchange allegedly responded twice through an email address that Binance had designated for law-enforcement requests from Russia and Belarus.
Binance’s current law-enforcement guidelines state that authorities generally need valid legal documentation, such as a court order, police order or warrant, before customer information can be provided during a criminal investigation.
The exchange has said it cooperates with lawful law-enforcement requests while taking applicable privacy, regulatory and legal requirements into account.
Binance has not publicly confirmed the specific details of the Belenkiy case.
Binance Had Already Left the Russian Market
The reported disclosure comes nearly three years after Binance announced its exit from Russia.
In September 2023, Binance agreed to sell its Russian business to CommEX as part of a complete withdrawal from the market. The exchange said operating in Russia was no longer compatible with its compliance strategy.
Binance also stated that it would not maintain a revenue-sharing arrangement with CommEX or retain an option to buy back the business.
The latest report therefore concerns customer information held by Binance rather than evidence that the exchange continued normal Russian operations after its exit.
The Case Raises Data Privacy Questions
The disclosure could raise questions about cross-border data protection, particularly because Belenkiy reportedly held a Bulgarian residency permit.
If his Binance account had been subject to European data-protection rules, the transfer of personal information to Russian authorities could face additional legal requirements.
However, Reuters reported that it could not independently establish whether Belenkiy was registered with Binance as an EU customer.
Binance also declined to discuss whether the disclosure complied with European data-protection requirements.
That leaves the legal basis for the transfer and the privacy rules applicable to Belenkiy’s account unclear.
Centralized Exchanges Can Link Crypto Transactions to Users
The case highlights an important difference between blockchain transactions and centralized exchange activity.
Blockchain networks can publicly record transactions without directly revealing the identity of the wallet owner. Centralized exchanges, however, generally collect customer information through Know Your Customer procedures.
That means exchanges can potentially connect blockchain activity with:
When authorities obtain legally valid access to exchange records, previously pseudonymous blockchain activity can therefore become linked to a specific individual.
Binance Case Highlights Exchange Privacy Risks
The Belenkiy case shows why cryptocurrency users should understand the privacy implications of keeping assets on centralized exchanges.
Self-custody does not eliminate blockchain transparency, but it removes the centralized exchange as the primary custodian of the user's identity and transaction records.
For exchanges, meanwhile, the case demonstrates the difficult balance between complying with law-enforcement requests and protecting customer information across different jurisdictions.
What Happens Next?
Binance has not confirmed exactly what information it provided to Russian authorities or explained the specific legal basis for the disclosure.
Questions also remain over whether Belenkiy was considered an EU customer and which data-protection rules applied when the request was processed.
The case does not establish that Binance broke the law. However, it highlights how centralized exchanges can become a bridge between pseudonymous blockchain activity and personally identifiable information when authorities submit legal requests.
For the crypto industry, the episode is another reminder that exchange privacy policies, jurisdiction and law-enforcement cooperation can be just as important as the transparency of the underlying blockchain.
