Crypto exchanges Huobi and KuCoin continue to provide services to users of sanctioned Russian banks, according to a report from Politico on Feb. 24.

The news publication cited a report from Inca Digital to that effect. Inca’s report specifically suggests that clients of sanctioned Russian banks can use bank-issued debit cards to transact on either exchange’s peer-to-peer cryptocurrency trading platform.

Huobi and Kucoin reportedly do not directly accept funds from any sanctioned banks. However, Inca Digital CEO Adam Zarazinski asserts that the activities above directly violate international sanctions despite the existence of an apparent “loophole.”
