Despite industry pushback, the U.S. Treasury is not giving an inch in the fight over its sanctions on Tornado Cash.
The Treasury’s Office of Foreign Asset Control has in fact added a designation to the Ethereum-based crypto mixer. In addition to the original August sanctions under an executive order on cybercrime, OFAC is now designating Tornado Cash under an order on North Korea’s nuclear proliferation.
“This action is part of the United States’ ongoing efforts to limit the DPRK’s ability to advance its unlawful weapons of mass destruction (WMD) and ballistic missile programs,” the announcement said, noting that the re-designation “includes an additional basis for the designation of Tornado Cash regarding its support for DPRK activities.“
The announcement effectively entrenches OFAC’s treatment of Tornado Cash as a threat to national security.
The double designation also flies in the face of multiple lawsuits from the crypto industry and advocates aiming to roll back the original sanctions. Those suits argue that Tornado Cash, as a decentralized smart contract, cannot be an “entity” as the terms of OFAC’s sanctioning authority lay out. OFAC “exceeded their statutory authority because Tornado Cash is used to complete functions that do not include ‘any property in which any foreign country or a national thereof has any interest,'” the nonprofit Coin Center argued in their case.
A new FAQ from OFAC addresses this argument quite directly. “OFAC designated the entity known as Tornado Cash, which is a ‘partnership, association, joint venture, corporation, group, subgroup, or other organization’ that may be designated pursuant to IEEPA,” the office wrote in its latest guidance.
In March of this year, an exploit saw bad actors get away with almost $600 million from Ronin, an Ethereum sidechain that Axie Infinity ran on. OFAC linked the hack to North Korea only weeks later.
