The US has moved against crypto wallets linked to Iran’s Islamic Revolutionary Guard Corps, with Tether freezing $344 million in USDT as part of a broader sanctions push called Operation Economic Fury.
Summary
US authorities sanctioned multiple crypto wallets tied to Iran’s IRGC, leading to a $344 million USDT freeze.
Tether blocked two Tron addresses holding about $213 million and $131 million after action tied to US authorities.
The move is part of a wider campaign aimed at cutting off Iran’s financial channels during the ongoing conflict.
Treasury Secretary Scott Bessent said the effort is focused on tracking and disrupting money flows linked to Tehran.
According to the announcement, the freeze was carried out through Tether at the smart contract level, meaning the Tron network itself kept running, but the funds in those addresses were effectively locked and unable to move.
How the Freeze Worked
The two wallets were blacklisted directly through Tether’s issuer controls.
That matters because this was not a blockchain shutdown. It was a stablecoin-level freeze.
One wallet reportedly held about $213 million in USDT, while the second held around $131 million.
Investigators said on-chain patterns matched activity associated with known IRGC-linked wallets, including large transfers and interactions tied to Iranian financial channels.
The move shows how stablecoin issuers can increasingly act as enforcement points in sanctions cases.
Tether’s Growing Role in Enforcement
This was one of the largest crypto freezes tied to Iran so far.
Tether has used its freezing powers before, but this action shows how much its role in sanctions enforcement has grown.
Rather than targeting only exchanges or intermediaries, authorities are now combining wallet sanctions with direct asset freezes.
That creates a two-layer strategy:
Target the infrastructure
Freeze the funds
The goal appears to be disrupting how sanctioned actors move money through digital assets outside traditional banking.
What It Means for Iran’s Crypto Use
The move puts pressure on visible on-chain funds, but questions remain over how much it changes Iran’s broader financial strategy.
Iran has increasingly used crypto as part of its financial system, including mining, digital payments, and alternative settlement channels.
Some analysts say targeting wallets alone may not be enough and that enforcement may increasingly focus on outside networks helping facilitate those flows.
Still, a $344 million freeze is significant.
It also sends a message that stablecoins are not beyond the reach of sanctions enforcement.
Bigger Picture
This is another reminder that crypto is becoming part of geopolitics, not just finance.
Stablecoins are being used not only for payments and markets, but also as tools in sanctions enforcement and state-level financial strategy.
And in this case, Tether ended up playing a central role in both.
