The US Treasury Department's Office of Foreign Assets Control (OFAC) announced sanctions against six entities located in Liberia, India, Vietnam, Lebanon, and Kuwait. The sanctioned entities are suspected of facilitating commodity transportation and financial transactions, including providing cryptocurrency to the Islamic Revolutionary Guard Corps' Quds Force (IRGC-QF), Houthi militants, and Hezbollah. Among them is Tawfiq Muhammad Sa'id al-Law, a Syrian currency exchange dealer based in Lebanon. The Treasury Department specifically stated that Sa'id al-Law provided a digital wallet to Hezbollah for receiving funds from IRGC-QF commodity sales and conducting cryptocurrency transfers.

Ben Hutten, a partner at Orrick Law Firm, stated that US regulators have been paying attention to cryptocurrencies, and even though miners are not currently a focus of attention, they have reason to be cautious. If miners provide services to individuals on the Office of Foreign Assets Control (OFAC) sanctions list, OFAC may consider it as substantial support for the sanctioned individuals and may become a basis for imposing sanctions on the service provider. Christopher Bendiksen, head of Bitcoin research at CoinShares, also agrees with this view and believes that some miners will eventually start reviewing transactions related to addresses on the OFAC list, which will become a cost of doing business for them in the West.

According to Golden Finance, Ethereum MEV-relay bloXroute Lab stated that it has started rejecting blocks containing transactions with addresses listed on the Office of Foreign Assets Control (OFAC) specially designated nationals and blocked persons list (SDN) since December 18.

Virtual currency exchange CoinList, located in San Francisco, has reached a settlement with the US Treasury Department's Office of Foreign Assets Control (OFAC) for violating sanctions.

OFAC stated that the exchange processed 989 transactions on behalf of users residing in Crimea between April 2020 and May 2022, in violation of OFAC's sanctions against Russia/Ukraine.
