Israel Seizes Iran-Linked Wallets Holding Up to $1.5B USDT in Landmark Crypto Crackdown

Digital assets become geopolitical weapons as Israel strikes massive blow against Iran's financial networks.

The $1.5 billion seizure—one of the largest in crypto history—exposes how stablecoins now fuel shadow economies. Tether's USDT, designed for seamless transfers, just became the ultimate tool for state-level financial warfare.

Forget banking sanctions—this is the new frontier. Nation-states now play whack-a-mole with blockchain addresses instead of freezing traditional accounts. The irony? Regulators still treat crypto like it's all monkey JPEGs and meme coins while real money moves in plain sight.

Welcome to the future of finance—where your stablecoin wallet might just become a national security target.

Will the USDT confiscation have an impact? 

Crypto wallets remain anonymous or at least pseudonymous. Seizing wallets is also impossible without access to private keys. USDT can be frozen, but there are no reports of involving Tether or TRON in their role of controlling the illegal usage of stablecoins. 

In general, USDT illegal usage has been handled by the T3 Financial Crime Unit, where tron and Tether collaborate and freeze some known wallets linked to scams. However, the crime unit has frozen a limited amount of wallets. A total of 2,459 addresses have been banned to date. Based on Eliptic data, Tether blacklisted a total of 39 addresses from the list.

The recently seized wallets were active in early 2025, when most of the fund transfers happened, leaving a small residual balance. 

Despite the risk of freezing stablecoins, usage is still NEAR peak levels. On-chain transactions remain permissionless, and the danger of having assets frozen does not prevent most regular users from interacting with USDT. 

USDT freezes are still rare

The T3 financial crime unit has frozen and recovered up to $100M USDT to date, mostly linked to personal scams, as Cryptopolitan reported. Banned and blacklisted wallets hold a total of $1.5B on Ethereum.  

The T3 unit freezes wallets on an ad-hoc basis, after specific collaboration with exchanges. It remains unknown if the blacklisted wallets will be watched, or if there WOULD be efforts to freeze and burn their assets. 

The interactions with the terrorism-linked wallets are also still verified. Some of the wallets may belong to contracts or services, which only interacted with the IRGC addresses.
