The United States has now seized or frozen nearly $1 billion in crypto assets tied to Iran, according to Treasury Secretary Scott Bessent. The reporting describes it as one of the clearest examples yet of state power reaching directly into digital-asset infrastructure. The action comes under Operation Economic Fury, but of the headline number, the best-documented piece is a freeze of $344 million in Tether stablecoin—USDT—locked at the direction of U.S. authorities. That freeze hit two Tron wallets linked to Iranian financial networks. Other reporting puts the confirmed combined freezes and seizures closer to roughly $500 million, with the higher number mixing both types of action. That difference matters: a seizure means the government takes legal possession, while a freeze just blocks movement of the assets.
