When Russian investigators detained IT specialist Yuri Belenkiy in September 2025, Binance had been formally out of Russia for nearly two years. Its buyer data, nevertheless, have been nonetheless obtainable.
Regulation enforcement paperwork reviewed by Reuters present that Binance provided private and transaction information later included right into a Russian terrorism-financing case towards Belenkiy.
The 49-year-old Russian passport holder, who additionally has a Bulgarian residence allow, is accused of sending greater than $700 in crypto to Ukrainian recipients between January 2023 and March 2024. Russian authorities say the funds supported a bunch linked to the Azov army unit, which Moscow designates as a terrorist group.
Belenkiy is in a Russian jail awaiting trial, and the allegations haven’t been adjudicated.
The case exposes a tough restrict to what an trade exit means for its former clients. An organization can promote its native operation, cease onboarding customers, and take away its employees. It might nonetheless retain years of passports, addresses, and account histories as a result of monetary regulation requires recordkeeping. These information can be found and accessible lengthy after the business relationship that created them ends.
Withdrawing crypto may finish the custody relationship, however copies of the identification and transaction information already submitted can keep behind.
The enterprise left, however the archive stayed
Binance introduced the sale of its Russian enterprise to CommEX on Sept. 27, 2023. It introduced the deal as an entire exit, stated working in Russia not match its compliance technique and denied any persevering with income break up or buyback choice. CryptoSlate's reporting on the time described the sale and Binance's denial of possession ties to CommEX.
The paperwork reviewed by Reuters describe a later regulation enforcement request for transaction data linked with Belenkiy. A response despatched from an tackle utilizing the area binanceholdings.ru included a file along with his date of beginning, residential tackle, telephone quantity, and passport quantity. It additionally contained copies of his passport and Bulgarian residence allow, in keeping with the report.
Russian investigators folded the transaction historical past into their case. One request additionally sought particulars of different Binance clients who transferred funds to the identical pockets. Reuters couldn’t set up whether or not Binance recognized any of these customers.
| Date | Occasion |
|---|---|
| Sept. 27, 2023 | Binance proclaims sale of its whole Russian enterprise to CommEX |
| January 2023 to March 2024 | Transactions cited by Russian authorities happen |
| September 2025 | Russian authorities detain Belenkiy |
| October 2025 | Investigative Committee presents terrorism-financing allegation |
| 2025 request interval | Binance buyer and transaction information enter the investigative file |
The paperwork cease in need of establishing that Binance secretly stored working its outdated Russian trade. Knowledge cooperation and buyer servicing, nevertheless, are totally different actions. The largest lesson right here is that the sensible actuality of leaving a jurisdiction relies upon closely on which layer is examined.
An working exit can finish new accounts and buying and selling. A company exit can take away the native entity or employees. A knowledge exit would require deletion, switch, or authorized isolation of historic data. Monetary corporations not often promise the final one as a result of anti-money laundering and record-retention guidelines typically require them to protect buyer materials.
Binance instructed Reuters that it cooperates with lawful regulation enforcement requests underneath relevant authorized, privateness and regulatory necessities. The trade additionally stated it doesn’t resolve what fees authorities file or how they use info as soon as produced.
Its public authorities regulation enforcement tips say officers should present supporting paperwork and a sound courtroom order, police order, or warrant from a reliable jurisdiction. Requests should state their authorized foundation. Binance says it might require extra info to verify that disclosure is lawful and should notify the person until a sound order or warrant bars discover. Preservation requests preserve data for 90 days and may be renewed.
These procedures clarify how disclosure is meant to work. The general public document doesn't set up which Binance authorized entity managed Belenkiy's account, which regulation compelled the manufacturing, or whether or not he obtained discover.
KYC turns a public transaction right into a named historical past
A blockchain data transfers underneath addresses reasonably than passport names. That pseudonymity may be highly effective till an tackle touches a centralized trade.
An trade's know-your-customer file provides the lacking key. It could actually join a pockets or deposit tackle to a reputation, telephone quantity, tackle, doc picture, and gadget information. Inner transaction data can add the route between an on-chain switch and an trade account. As soon as the identification file and public ledger are joined, investigators can reconstruct exercise that occurred years earlier.
That's the crypto privateness paradox that regulation created. Governments required centralized exchanges to gather extra figuring out information to discourage cash laundering, sanctions evasion and fraud. The identical system produces a sturdy archive that can be utilized in tax circumstances, political investigations, or prosecutions underneath nationwide safety legal guidelines.
The permanence works in each instructions. A blockchain can protect proof of legal finance. It could actually additionally protect a lawful donation {that a} authorities later classifies as legal, however the ledger can’t inform these makes use of aside. The authorized system that attaches a reputation and offense to the switch does that.
Belenkiy's case is particularly delicate as a result of Russian authorities classify Azov as a terrorist group and deal with associated assist accordingly. A donation framed elsewhere as help to Ukraine can carry a radically totally different authorized which means inside Russia. Binance's function was to offer data, to not make that classification.
Because of this modernized identification programs have gotten central to crypto coverage. CryptoSlate has lined proposals to make use of zero-knowledge proofs for monetary compliance, permitting a buyer to show an attribute with out handing each verifier a reusable copy of the underlying doc. Such programs protect lawful disclosure whereas decreasing what number of full identification information exist throughout intermediaries.
Privateness rights don't assure deletion
Belenkiy's Bulgarian residence allow provides an unresolved European difficulty. A residence card alone can’t set up that he was a buyer of an EU Binance entity or that the Basic Knowledge Safety Regulation (GDPR) ruled the disclosure. Reuters couldn't decide his registration entity, so the obtainable info provide no foundation for alleging that Binance violated EU regulation.
If an EU entity managed the account, GDPR guidelines would nonetheless require a authorized foundation and safeguards for sending private information exterior the bloc. The European Fee's steerage on worldwide transfers explains that European protections can comply with the info. Corporations want an adequacy choice, authorized safeguards, or a sound derogation.
Nor does GDPR create an unconditional proper to erase an outdated trade account. The Fee's clarification of particular person rights says erasure may be refused when processing is required by regulation or wanted for authorized claims. Its instance is a financial institution that should retain former buyer particulars for 10 years even when the shopper asks for deletion.
That distinction leaves customers with two very totally different types of management. Transferring cash to self-custody removes the trade from future custody and might restrict new account data. Closing an account might cease future use. Neither motion erases transactions already written to a public chain or data an middleman should legally preserve.
Binance's Russian exit was actual on the degree it introduced: it bought the enterprise and wound down native service. Belenkiy's prosecution exposes the additional layer carried by former clients. Corporations go away markets on a company timetable. Private information leaves, if it leaves in any respect, on a authorized one.
