"Only after ShapeShift received an administrative subpoena from OFAC did it adopt a sanctions compliance program," the Treasury Department's announcement read.
"ShapeShift had reason to know that such users were located in sanctioned jurisdictions, including on the basis of IP address data," the Treasury Department continued, adding that the exchange "conveyed economic benefit to persons in several jurisdictions subject to OFAC sanctions and thereby harmed the integrity of multiple OFAC sanctions programs."
It said that the fine was small as ShapeShift is a shuttered exchange with limited assets. ShapeShift closed in 2021.
The exchange—founded in 2014, incorporated in Switzerland, and run out of Denver, Colorado before it shut down—allowed users to swap digital coins and tokens without having to sign up with typical know-your-customer or KYC details, such as addresses or bank details. Clients could therefore trade cryptocurrencies like Bitcoin and Ethereum with a degree of anonymity.
ShapeShift received early funding from early crypto bigwigs like Roger "Bitcoin Jesus" Ver and Digital Currency Group CEO Barry Silbert.
But the exchange ran into trouble when the Securities and Exchange Commission started investigating the platform for not registering as a broker or exchange.
ShapeShift last year agreed to a cease-and-desist order and a $275,000 fine to settle allegations from the SEC.
