The U.S. Treasury’s Office of Foreign Assets Control (OFAC) adds four cryptocurrency wallet addresses tied to Iran’s central bank and armed forces to its sanctions list, according to reporting from Decrypt and CoinDesk. The targeted wallets use the TRON network and hold digital assets valued at $131 million, with one report noting the addresses collectively held more than $165 million before the freeze. After the sanctions designations, Tether blocks activity involving the affected wallets. The freeze prevents the specific funds from being transferred or redeemed, limiting the designated parties’ ability to move or access those holdings. Both sources describe the action as part of a broader U.S. financial pressure campaign against Iran, focused on cutting off sanctioned entities from the cryptocurrency system. The reports also frame the move as a continuation of Washington’s efforts to enforce sanctions through crypto-related compliance, including by freezing assets associated with addresses linked to Iran’s governmental and military structures.
