What to know:
- U.S. sanctions targeted Iranian crypto wallets, leading to the freeze of more than $130 million in USDT, officials said publicly.
- According to onchain analyst Specter, Tether froze four Tron wallets linked to sanctioned Iranian entities before the Treasury announced the designations.
- Tether said it has assisted more than 2,300 investigations and frozen over $4.4 billion in assets supporting global law enforcement.
The United States has escalated its sanctions campaign against Iran by targeting cryptocurrency wallets tied to the country’s financial network. The action resulted in the freeze of more than $130 million in USDT and highlighted the growing role of digital assets in sanctions enforcement.
Treasury Secretary Scott Bessent said the Office of Foreign Assets Control designated several cryptocurrency wallets connected to the Central Bank of Iran. He stated that the move aims to disrupt illicit financial activity and prevent the Iranian government from accessing revenue generated through unlawful schemes involving digital assets.
“We will aggressively follow the money and deny the Iranian regime access to the proceeds of its illicit revenue schemes,” Bessent wrote in a post on X.
According to onchain analyst Specter, Tether froze four Tron wallets holding approximately $131 million in USDT just minutes before Bessent announced the sanctions. Specter said the addresses were linked to both the Central Bank of Iran and the Islamic Revolutionary Guard Corps.
Additionally, Specter reported that most of the funds had previously moved through payment service provider DTC Pay and cryptocurrency exchange Bitso. However, the analyst noted that the reason behind the blacklist was still unknown when the wallets were frozen.

Treasury Action Coincides With Tether Wallet Freeze
The close timing of both announcements attracted attention across the cryptocurrency industry. Although Bessent did not directly reference Tether’s wallet freeze, the entities identified in the Treasury sanctions matched those highlighted by Specter.
Consequently, the developments pointed to a broader enforcement effort involving government sanctions and blockchain-based compliance measures. However, neither the Treasury Department nor Tether confirmed whether the actions were coordinated.
Besides targeting traditional financial channels, U.S. authorities have increasingly focused on cryptocurrencies used by sanctioned organizations. Officials argue that digital assets have become another avenue for moving funds outside conventional banking systems.
As a result, regulators have expanded cooperation with blockchain analytics firms and cryptocurrency companies to identify and restrict wallets linked to illicit financial activity.
Tether Highlights Broader Compliance Efforts
The latest freeze follows several large enforcement actions involving USDT linked to sanctioned entities and criminal investigations. In April, Tether said it supported the freeze of more than $344 million in USDT across two Tron addresses after U.S. authorities identified the wallets as being connected to illicit activity.
Moreover, the stablecoin issuer said it works with more than 340 law enforcement agencies across 65 countries. The company also disclosed that it has assisted more than 2,300 investigations involving digital assets.
Tether further stated that it has frozen more than $4.4 billion in cryptocurrency throughout its compliance efforts. Additionally, more than $2.1 billion of those assets were connected to requests from U.S. authorities.
Conclusion
The latest sanctions underscore how cryptocurrency enforcement has become part of broader U.S. efforts to restrict Iran’s financial networks. Meanwhile, the reported freeze of $131 million in USDT reflects the increasing involvement of stablecoin issuers in supporting sanctions compliance and law enforcement investigations.
