US freezes $344 million in cryptocurrency linked to Iran over sanctions

The United States froze $344 million in cryptocurrency assets tied to Iran on April 24, according to Treasury Secretary Scott Bessent. The action targets multiple cryptocurrency wallets as Washington intensifies pressure on Tehran amid Middle East energy supply disruptions caused by ongoing conflict.

  • Iran's cryptocurrency holdings reached $7.8 billion in 2025, per Chainalysis reports.
  • The Islamic Revolutionary Guard Corps held about half of Iran's crypto assets in late 2025.
  • Tether cooperated with OFAC to freeze the wallets after U.S. authorities flagged suspicious activity.
