US sanctions four Iran central bank crypto wallets, Tether freezes $131M

The United States government has added four cryptocurrency wallets linked to Iran's central bank to its sanctions list. The wallets, built on the TRON blockchain, collectively held over $165 million at the time of the action. In response, stablecoin issuer Tether moved to freeze approximately $131 million worth of assets contained in those addresses. The sanctions effectively block the flagged funds from being transferred or redeemed. The move reflects ongoing U.S. efforts to use financial tools to restrict Iran's access to digital assets.
