Monday’s sanctions will prohibit US persons, and those subject to US jurisdiction, from using the virtual currency mixer.
A virtual currency mixer receives a number of transactions and mixes them together before sending them to their ultimate destination to make it harder to trace where the money came from or where it’s going.
As part of Monday’s action, 44 cryptocurrency wallets linked to Tornado Cash were sanctioned by the US government. The Treasury official said Tornado Cash had been previously identified as an entity of concern, but declined to say for how long and where the organization may be based or what individuals may be operating it.
“Despite public assurances otherwise, Tornado Cash has repeatedly failed to impose effective controls designed to stop it from laundering funds for malicious cyber actors on a regular basis and without basic measures to address its risks,” Under Secretary of the Treasury for Terrorism and Financial Intelligence Brian Nelson said in a statement. “Treasury will continue to aggressively pursue actions against mixers that launder virtual currency for criminals and those who assist them.”
According to the Treasury official, Tornado Cash is one of the largest virtual currency mixers that has been identified by the US government. It is only the second time the Department has sanctioned such an entity.
In May, the Treasury Department sanctioned another virtual currency mixer, Blender.io, which it said was used by North Korea “to support its malicious cyber activities and money laundering of stolen virtual currency.”
The official said they hoped Monday’s sanctions would send a message to the private sector and partner nations to encourage them to develop regulations when it comes to virtual currency.
