According to crypto data aggregator Dune Analytics, on Monday, Circle, the issuer of the USD Coin stablecoin (USDC), froze over 75,000 USDC worth of funds linked to the 44 Tornado Cash addresses sanctioned by the U.S. Office of Foreign Assets Control's (OFAC) Specially Designated Nationals and Blocked Persons (SDN) list. Tornado Cash is a decentralized application, or dApp, used to obfuscate the trail of previous cryptocurrency transactions on the Ethereum blockchain.

All U.S. persons and entities are prohibited from interacting with the virtual currency mixer's USDC and Ethereum smart contract addresses on the SDN list. Penalties for willful noncompliance can range from fines of $50,000 to $10,000,000 and 10 to 30 years imprisonment.
