The U.S. Treasury Department’s sanctions watchdog removed Tornado Cash from its global blacklist Friday.
The crypto mixing tool has been accused of helping North Korea’s Lazarus Group launder stolen funds from its various hacks and thefts, and the U.S. Treasury Department’s Office of Foreign Asset Control sanctioned it — meaning no U.S. person or anyone doing business with the U.S. could engage with it financially — multiple times. However, a federal appeals court ruled last November that OFAC couldn’t sanction Tornado Cash’s smart contracts because they weren’t the “property” of any foreign national.
“We remain deeply concerned about the significant state-sponsored hacking and money laundering campaign aimed at stealing, acquiring, and deploying digital assets for the Democratic People’s Republic of Korea (DPRK) and the Kim regime,” a press release from the U.S. Treasury Department said.
Another release from OFAC lists over 100 Ethereum (ETH) addresses that are being removed from the Specially Designated Nationals list, which is the record Treasury uses for maintaining its blacklist.
Roman Storm, one of the co-founders of Tornado Cash, faces a criminal trial this July over his alleged role developing the smart contracts and protocols. Another developer was charged but has not yet been arrested.
In a statement, Treasury Secretary Scott Bessent said the U.S. needs to “secure the digital asset industry from abuse by North Korea and other illicit actors.”
In a Monday court filing, referenced by the Treasury in Friday’s statement, the Treasury Department suggested it might not go so far as to remove the sanctions entirely.
“Vacating the designation of Tornado Cash in its entirety could have significantly ‘disruptive consequences’ for national security and law enforcement,” the filing said.
The TORN token jumped 40% in the minutes after Treasury’s statement.
