Cryptocurrency derivatives trading platform dYdX said it blocked some users’ accounts with funds linked to Tornado Cash, including mistakenly suspending some that never directly engaged with the controversial mixer.
In a Wednesday blog post, dYdX said it had “unbanned certain accounts” that the derivatives platform had blocked in response to the Office of Foreign Assets Control of the United States Treasury Department adding Tornado Cash to its list of Specially Designated Nationals, or SDNs. According to dYdX, its compliance provider flagged many accounts believed to be linked to Tornado Cash, which the platform subsequently blocked — despite the fact some had never dealt with the crypto mixer. The platform said it has used compliance vendors to scan for and flag accounts potentially associated with illicit activities, including sanctions lists for many countries.
“This sudden influx of flags affected many account holders that never directly engaged with Tornado Cash, and often such users do not realize the origin of the funds transferred to them during various transactions prior to interacting with our platform, but we must nevertheless maintain certain restrictions,” said dYdX.
