The U.S. Treasury Department has sanctioned two cryptocurrency exchanges, "Shellbit" and "Avan Tether," that were used to launder funds for the Iranian regime. These exchanges supplied laundered cryptocurrencies to Iran's Islamic Revolutionary Guard Corps through online gambling sites, providing financial support to the Iranian government. This is part of a U.S. strategy to strengthen economic pressure on Iran by cracking down on digital assets and shadow financial networks. The Treasury Department has stated that it will continue to track and dismantle illegal financial networks used by the Iranian regime.
