Coinpayments is a Canadian company that has been around since 2013 and provides blockchain management solutions, including digital wallets. The company is, among other things, an online platform for storing and trading digital currencies of various types as well as converting digital currencies held on the platform to other digital currencies through third-party services that allow platform users to convert between digital currencies at market rates.
In practice, when a user of the platform requests to convert a virtual currency, the Coinpayments system processes the request, checks the balances of the user on the platform and sends a request to the cash database on the platform in order to withdraw the requested amount for currency conversion. The system then sends the virtual currency for conversion by an external vendor who accepts the virtual currency and converts the currency as requested. In the final step, the converted virtual currency is sent to the Coinpayments platform which receives the converted currency into the user account and updates the user balances log to reflect the converted virtual currency deposit.
According to the indictment, in the period between 14.10.17 and 13.11.17 or close to this period, a software failure occurred on the platform, which was reflected in a delay in communication between systems on the platform. This failure allowed platform users to submit multiple digital currency conversion requests before the system “had time” to properly update the balance sheet in their account.

The company had to return the theft money to the users of the site; An amount of about $ 5.8 million which was taken from the cash database on the platform and belongs to all its users.

The indictment states that “at this point near 14.10.17, knowing that there was a failure in the platform that allows him to steal digital coins from the company by making repeated conversions between digital currencies without the converted currency being deducted from his account, the defendant decided to use the platform trick for several days. “The defendant returned to the platform and performed dozens of conversions between digital currencies, knowing that his account is not charged the conversion amount, so in fact he converts the same currency over and over again and each time receives a return for it.”
Thus, it was alleged in the indictment, taking advantage of the company’s mistake and without her knowledge, Dzebinski stole digital coins from the company through conversion operations.
