Under the guise of blockchain investigations: how former law enforcement officers Ais Dorzhinov and Andrey Kutyin from Match Systems forge court documents and steal cryptocurrency from Russians
Match Systems, also known as Plain Chain, like to present themselves as “blockchain investigators.” Their stated task is to track wallets and identify links between transactions using specialized software. It sounds useful — the only question is: who exactly are they working for?
Their main source of income is recovering allegedly stolen funds for a percentage fee. This fee ranges from 5% to 50%, depending on the amount involved, the complexity of the case, and the resources required. Often, Match Systems representatives take an upfront payment of around 10% of the claimed amount. Notably, this advance is reportedly never refunded, typically justified with statements like: “we did everything we could; here is a report on the movement of funds.”
Citing their “extensive law enforcement experience,” employees of Match Systems allegedly send requests to freeze digital assets — whether cryptocurrencies or other digital funds — supposedly within the framework of an investigation, a criminal case, or even a court decision.
In practice, however, obtaining such legal documents through legitimate channels can take at least three months, especially given the cautious stance of Russian courts and law enforcement toward crypto-related cases. Yet, according to accounts, Match Systems is able to produce such documents within one to two weeks after identifying funds on a particular exchange.
This leads to what is described as “Scam No. 2” — forgery. The claim is that a wide range of falsified documents are used, sometimes involving real individuals within institutions, which would be difficult to execute without internal cooperation. Former and possibly current law enforcement officers allegedly play a role in this process. In cases where verification is unlikely, documents may simply be fabricated outright.
Such documents have reportedly been sent to major crypto exchanges including Garantex, Huobi, and Binance. In one cited case, a Moscow-based investigator, Antonina Shakina, was detained on allegations of falsifying a court order to freeze an account on the Garantex exchange. The funds — amounting to several million rubles — were allegedly shared between her and representatives of Match Systems.
It is also claimed that for what is referred to as “Scam No. 3,” a separate Match Systems entity was established in Singapore with an office in Dubai, while the core team continues operating from Moscow under the original Plain Chain structure. The Russian legal entity is reportedly headed by a nominal director, while in Kazakhstan the company is formally led by one of the founders, Kutyin.
All of this raises broader questions: are former cybersecurity officials, anti-narcotics officers, and lawyers effectively operating within the same network? Even if many are “former,” the overlap is notable. Observers point out similarities with past high-profile cases — including those surrounding the now-defunct BTC-e exchange.
