The U.S. Treasury Department has added four cryptocurrency wallets tied to the Central Bank of Iran to its sanctions list, and Tether has frozen roughly $131 million of the funds held in those wallets. The move targets TRON-based addresses that together held more than $165 million, effectively preventing those assets from being transferred or redeemed.
The sanctioned wallets
The four wallets were added to the Office of Foreign Assets Control's sanctions list this week. They're all on the TRON blockchain, a network popular for stablecoin transfers. The combined balance was over $165 million, though Tether's freeze covered $131 million — the difference likely reflects funds already moved or held in other tokens.
Tether's freeze
Tether, the issuer of the USDT stablecoin, acted quickly after the Treasury's designation. The company froze the contents of those specific TRON addresses, meaning the USDT held there can't be transferred or redeemed for dollars. It's a rare but not unprecedented move for a stablecoin issuer to freeze funds on a sanctions list. Tether has done it before, but the scale here — over $131 million — is notable.
The Central Bank of Iran has been under U.S. sanctions for years, but this is one of the first times the Treasury has specifically named crypto wallets linked to the bank. The freeze shows that even on a decentralized blockchain, sanctioned entities can't count on stablecoins staying accessible. For Tether, it's a reminder that compliance with U.S. sanctions is non-negotiable, even for a global stablecoin.
The frozen funds remain locked on the TRON blockchain, with no clear path for the Central Bank of Iran to access them. Whether Tether will eventually unfreeze or the U.S. will seek forfeiture remains an open question. For now, the wallets sit empty of usable USDT — a digital dead end for the sanctioned bank.
