A US Senate Democrats investigation has found that the Iranian regime heavily utilizes Tether’s USDT stablecoin, identifying it as one of the country's primary payment methods. The report highlights the significant role the dollar-pegged asset plays in transactions linked to sanctioned entities. According to the Senate findings, 84% of more than 800 sanctioned crypto wallets exclusively or primarily use USDT. The investigation underscores the extent to which Tether's stablecoin has been integrated into financial activities associated with Iran despite international sanctions.
