Arkham, a blockchain analytics company, has made public a detailed, searchable map of cryptocurrency wallets tied to Iran’s central bank, revealing a clearer picture of Tehran’s covert digital asset operations. This development makes it easier for investigators and the public to trace the flow of Iranian funds through the crypto sphere, particularly those connected to sanctions enforcement efforts.
The map focuses primarily on two Tron-based wallets flagged by the US Treasury as part of its sanctions against Iran. These wallets were designated in April under the Specially Designated Nationals list, identified as assets of Bank Markazi Jomhouri Islami Iran, the nation's central bank. The Treasury linked these wallets to Iran’s Islamic Revolutionary Guard Corps-Qods Force and Hezbollah, freezing approximately $344 million in crypto assets. Stablecoin issuer Tether confirmed it froze the funds following requests from US authorities, citing illicit activities tied to these accounts.
Arkham’s research groups these sanctioned wallets under a Central Bank of Iran entity page, creating a hub for tracing connected wallets and transactional flows. The frozen assets are mainly TRC-20 tokens—a token standard on the Tron network—which include USDT, the world’s most widely used stablecoin.
The system Iran uses to move crypto funds is complex and intentionally designed for concealment. According to Chainalysis, Iranian oil revenues navigate through numerous intermediaries such as brokers, intermediary wallets, cross-chain bridges, and decentralized finance protocols. Transactions move stepwise through this layered pipeline, obscuring the origin of funds before arriving at wallets linked to Iran’s central bank and IRGC-controlled groups.
A Tron spokesperson clarified that the network itself cannot monitor or block individual transactions but highlighted the role of the T3 Financial Crime Unit—a collaborative initiative launched in 2024 by TRON, Tether, and TRM Labs. This unit works with law enforcement to detect and freeze funds related to sanctioned organizations, reportedly halting hundreds of millions tied to terrorism financing.
Iran’s involvement in cryptocurrency extends beyond evading sanctions. Industry estimates from TRM Labs and Chainalysis suggest that Iran’s crypto transaction volumes reached billions in recent years. Further, authorities in Tehran are reportedly exploring crypto-denominated tolls on vessels passing through the Strait of Hormuz, hinting at digital assets as a potential new revenue source amid economic pressures.
