The world’s largest crypto exchange, Binance, released last-call notifications to its Russian users, urging them to complete their off-boarding process by withdrawing all of their money from the platform by December 29th, according to a report by RBK daily published on Thursday.

The exchange told its its Russian users they would need to transfer their accounts and withdraw their funds from Binance, placing them into any other crypto platform, such as the recently launched CommEX exchange, as after the deadline expires, all existing ruble deposits will be shut down.

RBK reported that the technical support division of Binance said that the notifications were sent to users whose “location is temporarily or permanently determined [to be] on the territory of the Russian Federation.”

In November, Binance had said that it would cease providing Russian ruble deposits, in preparation for leaving the sanctioned nation’s markets.

It had been revealed in September that the crypto exchange had decided to sell its Russia business so as to comply with Western sanctions on Moscow. CommEx purchased Binance’s Russian operations for an undisclosed sum, with Binance gradually withdrawing its services over several months.

The move came as there were reports of a US Department of Justice investigation into whether Russian customers were capable of accessing the platform, which could have been a violation of the US sanctions.

After Western sanctions cut Russian citizens off from global payment networks, people increasingly turned to the use of crypto exchanges for their financial transactions.
