The Trump administration has frozen $344 million in cryptocurrency linked to Iran, intensifying economic pressure on Tehran amid stalled diplomatic efforts. Treasury Secretary Scott Bessent announced sanctions on multiple crypto wallets associated with the Iranian regime, emphasizing the US's commitment to targeting financial channels tied to Tehran. Tether, a leading stablecoin issuer, confirmed it froze the funds across two addresses following information from US authorities regarding unlawful activities. This move comes as a fragile ceasefire holds, with the US aiming to disrupt financial lifelines supporting the Iranian regime.
