The U.S. Treasury Department has released further clarifications on the sanction placed on the popular cryptocurrency mixer, Tornado Cash. The department stated that the sanction does not affect the rights of individuals in the U.S. to view and disseminate the open-source Tornado Cash code.

It made the clarification in a newly published Frequently Asked Questions (FAQs) on its website. While performing any transactions with the crypto mixer is prohibited, interacting with the open source code in ways that do not involve prohibited transactions is not prohibited, the Treasury said.

"U.S. persons would not be prohibited by U.S. sanctions regulations from copying the open-source code and making it available online for others to view, as well as discussing, teaching about, or including open-source code in written publications, such as textbooks, absent additional facts," the response said.

It added that the sanctions do not prohibit U.S. persons from visiting the archived copies of the deleted Tornado Cash website. They also will not be prohibited from visiting the website if it again becomes active on the internet. The response answers the question of what is prohibited as a result of OFAC's designation of Tornado Cash.

The Treasury also made several other clarifications. It revealed that individuals whose transactions - those made before the designation of the mixer - had been frozen can complete their transactions by filing a licensing request from the OFAC.

Additionally, it noted that wallets that have been the target of "dusting" transactions - where wallets received unsolicited and nominal amounts of crypto - will receive lenient enforcement as long as the "transactions have no other sanctions nexus besides Tornado
