Binance Data Disclosure to Russian Authorities Raises Cross-Border Compliance Questions
Binance provided Russian investigators with customer identity documents and transaction records that were later used in a terrorism-financing case against a Russian IT specialist who had donated cryptocurrency to Ukrainian military-linked fundraising campaigns, according to law-enforcement documents reviewed by Reuters.
The case concerns Yuri Belenkiy, a Russian national and Bulgarian resident who was detained in September 2025. Russia’s Investigative Committee alleged the following month that he had transferred more than US$700 to the Ukrainian military and to a group associated with the Azov Brigade or Azov Regiment. Russia designates Azov as a terrorist organisation. The designation and the underlying conflict are politically contested internationally, and the allegation against Belenkiy should not be treated as a conviction.
What data was provided
According to the documents, Russian investigators asked Binance to identify people who had sent cryptocurrency to a wallet promoted for donations to Ukrainian military causes. Replies sent from an address used for Russian and Belarusian law-enforcement requests included a data file identifying Belenkiy as the customer behind one transfer.
The material reportedly included his date of birth, address, telephone number and passport number, together with copies of his Russian passport and Bulgarian residency permit. Investigators also received confirmation linking him to the relevant transaction.
Binance told Reuters that, like other global financial institutions, it responds to lawful law-enforcement requests subject to applicable legal, privacy and regulatory requirements. The company said it does not determine criminal charges or how authorities subsequently use information supplied in an investigation.
Russia exit and the compliance question
The disclosure is notable because Binance announced in September 2023 that it was selling its entire Russian business and fully exiting the market, saying continued operations there were incompatible with its compliance strategy. Reuters reported that the exchange nonetheless retained a channel for responding to Russian law-enforcement requests.
Binance publicly describes law-enforcement cooperation as a routine part of its financial-crime compliance programme. Its own materials say its legal and compliance teams respond to official information requests, trace illicit fund flows and preserve evidence for investigations. The company says it has processed tens of thousands of law-enforcement requests globally.
The new case therefore raises a narrower but important compliance issue: how a global crypto platform should balance lawful government requests against privacy, data-transfer and jurisdictional obligations when the customer may be resident in another regulatory regime.
Reuters cited a crypto-regulation lawyer who said European data-protection rules could be relevant if Belenkiy was registered with Binance as an EU resident. Reuters was unable to establish whether that was the case, and no European regulator has publicly found that Binance breached GDPR in this matter.
For compliance teams, the case illustrates that law-enforcement cooperation is not simply a question of whether a request comes from an official authority. Cross-border data disclosures may also require analysis of the customer’s location, applicable privacy rules, data-transfer restrictions and the legal basis for responding.
