Treasury sanctions 134 ISIS-K crypto addresses; Tether freezes the Tron wallets

The U.S. Treasury's Office of Foreign Assets Control added 134 cryptocurrency wallet addresses linked to Islamic State–Khorasan (ISIS-K) to its sanctions listing on Wednesday, according to CoinDesk. The batch comprised 131 Tron addresses and 3 Monero addresses. Shortly after the designation, stablecoin issuer Tether froze the USDT balances held in all 131 Tron wallets.

The Tron addresses had received more than $1.4 million since 2023 and sent out more than $880,000, figures CoinDesk attributes to blockchain-analytics firm Chainalysis. Chainalysis said ISIS-K — the Islamic State affiliate active across Afghanistan, Pakistan and parts of Central Asia — used its media arm, al-Azaim Media Foundation, to solicit donations through websites and messaging platforms, and that it traced historical donation addresses for the group on the Tron, Monero and Bitcoin networks.

In a separate action the same day, OFAC sanctioned a Brazil-linked network tied to Primeiro Comando da Capital (PCC), which Treasury described as Latin America's largest criminal gang. Treasury said the network laundered more than $30 million in U.S.-generated illicit proceeds and used crypto to move funds back to Brazil.

Key facts

• OFAC added 134 addresses (131 Tron, 3 Monero) to the ISIS-K sanctions entry on Wednesday, July 1, 2026 — CoinDesk.
• The 131 Tron wallets received more than $1.4 million since 2023 and sent more than $880,000 — Chainalysis, via CoinDesk.
• Tether froze the USDT balances in all 131 Tron wallets — CoinDesk.
• OFAC separately sanctioned a PCC-linked Brazilian network said to have laundered more than $30 million — U.S. Treasury, via CoinDesk.
• For scale: Tether froze more than $182 million in USDT across five Tron wallets in January under its sanctions-compliance policy — CoinDesk.

The real-world read

The mechanics matter here. OFAC can list an address, but it can't move the money — the freeze depends on a centralized issuer. Tether's action is what actually locked the funds, which underscores how much sanctions enforcement on-chain now rests on one private company's compliance decisions. That's a double-edged point Cleartext won't gloss: it's effective, and it means USDT on Tron is freezable at will.

Note the figures come from an interested analytics vendor — Chainalysis sells the tracing tools that make stories like this possible, so its attribution of these wallets to ISIS-K is its own assessment, not an adjudicated fact. The $1.4 million "received" is a gross flow since 2023, not a current balance; with $880,000 already sent out, what Tether actually froze is unstated. And the three Monero addresses are listed but not frozen — Monero's privacy design leaves them beyond the reach of the Tron playbook, a limit the announcement doesn't dwell on.

One caveat on sourcing: this rests on a single secondary report. The underlying OFAC designation and Treasury statement are primary and public; we've cited CoinDesk's reading of them pending direct confirmation.

Opinion, and whose

• Chainalysis: the case highlights "stablecoin issuers' growing role in sanctions enforcement" — its framing, and a fair read of the mechanics, though it's also a firm with a commercial stake in that narrative.
