Tether, the world’s leading stablecoin issuer, has frozen the USDT balances in 131 TRON wallets after the Office of Foreign Assets Control (OFAC), a division of the U.S. Treasury, expanded its sanctions list. The update targeted wallets believed to be tied to ISIS K, a militant group active in Afghanistan, Pakistan, and parts of Central Asia. In all, a total of 134 crypto wallet addresses were added to the sanctions list: 131 on the TRON network and 3 on Monero.
134 crypto wallets added to OFAC sanctions list
U.S. regulatory authority OFAC included new wallet addresses said to be part of ISIS K’s financial network as it widened its sanctions regime. This move added 134 new cryptocurrency wallet identifiers to the group’s existing sanctions record, aiming to further restrict access to the global financial system for those involved in illicit activities.
Mini glossary: OFAC is the U.S. Treasury’s agency responsible for enforcing sanctions. The institution restricts financial transactions connected to individuals, companies, and wallets it adds to its sanctions list.
According to blockchain analytics company Chainalysis, OFAC has updated its ISIS K sanctions, adding 134 cryptocurrency wallets: 131 on the TRON network and 3 on Monero.
Chainalysis data shows that since 2023, the TRON wallets listed for sanctions have received over $1.4 million in funds, while more than $880,000 was transferred out during the same period. This high volume of transactions underlines the significance of these wallets’ activity before being blacklisted.
Tether blocks all sanctioned TRON wallet balances
Chainalysis further noted that the sanctioned TRON wallets had interacted with mainstream crypto services and, in some cases, sent funds to crypto conversion services operating out of Syria. In response, Tether moved swiftly to freeze all USDT holdings in the TRON addresses appearing on the updated sanctions list.
Although only government agencies have the legal authority to enforce sanctions, stablecoin issuers can technically freeze tokens circulating on public blockchains. Because Tether centrally issues USDT, it can rapidly implement such actions upon receiving enforcement requests from authorities.
By freezing tokens in sanctioned wallets, Tether demonstrated active coordination with law enforcement agencies.
Compliance actions accelerate in recent months
This latest enforcement step follows Tether’s recent freeze of $344 million in USDT held in two TRON wallets flagged by U.S. authorities for suspected illegal activity—a move ranked among the company’s most significant compliance operations to date.
Tether has reported that it has frozen over $4.4 billion in digital assets since collaborating with authorities, of which around $2.1 billion was tied to requests from U.S. agencies. The company also states it has assisted more than 2,300 investigations involving 340 institutions across 65 countries, solidifying its position as one of the leading names in the stablecoin sector.
The recent wave of sanctions highlights a tightening regulatory focus on cryptocurrency transactions linked to terrorist financing and other illicit activities. Financial institutions and virtual asset service providers are now expected to monitor and screen the newly designated wallet addresses as part of their compliance systems.
