A Tron wallet sanctioned by Iran’s central bank, OFAC, has been mapped by Arkham.

Blockchain Analytics Platform Arkham has published what it says is official, onchain crypto wallets issued to the Central Bank of Iran, making it publicly available to investigators and the general public to find Tron addresses of a pair of US sanctions.

As U.S. officials step up enforcement of sanctions related to terrorist financing and oil revenue, the move will include an investigation into how Iran-linked entities use stablecoin and blockchain networks to move money outside traditional banking channels.

Arkham's May 11 research post traces the wallets to Iran's central bank's internal page and browser, which it says can be used as a starting point to trace the firm's linked addresses and flows.

The map is based on two TRC-20 wallets that the US Treasury's Office of Foreign Assets Control (OFAC) added to its list of specially designated nationals on April 24 as belonging to Bank Markazi Jomhouri Islami Iran, citing links to the Islamic Revolutionary Guard Corps-Quds Force and Hezbollah.

As part of the move, U.S. officials blocked an estimated $344 million worth of cryptocurrencies linked to Iran, which Treasury Secretary Scott Bessant described as “an effort to systematically degrade Tehran's ability to generate, move and repatriate funds.” Separately, Tether said he was blocking the funds at the request of U.S. officials for “activities related to illegal activity,” without mentioning Iran in the public statement.

The Arkham wallet map shows the widespread push by blockchain analytics firms and stablecoin issuers to expose and disrupt the crypto infrastructures associated with Tron and Tether.

In an April 27 memo, Chainalysis described a multi-level stablecoin “pipeline” where Iranian oil revenue flows through brokers, intermediary wallets, chain bridges, and decentralized financial protocols before returning to accounts linked to the Central Bank of Iran and entities linked to the IRGC.

Iran's broad crypto footprint

Arkham's findings come against a broader backdrop of Iran's growing use of crypto. A February report on Iran's Digital Assets Footprint, citing estimates from TRM Labs and Chainalysis, put the country's total crypto transaction volume in 2018 at It will reach $11.4 billion by 2024 and $10 billion by 2025.

In May, Nobitex, Iran's largest crypto exchange, was reportedly linked to members of a powerful family linked to Supreme Leader Ali Khamenei and used as a key conduit between domestic users and offshore liquidity.

In April, Iran considered charging crypto-denominated fees for ships transiting the Strait of Hormuz, using digital assets as an additional revenue channel outside of traditional banking.

Separately, Cointelegraph reported Friday that Tether has lost more than $500 million across Ethereum and Tron in the most recent 30-day period, with $506 million of that on Tron, according to Blocksec's USDT freeze tracker.

A spokesperson for TRON told Cointelegraph that the network itself cannot monitor or block individual transactions, but that the collaboration between TRON, Tether and TRM Labs, launched in 2024, is the main channel to combat attacks, saying it will work with law enforcement to “block hundreds of millions of funds.” Teter declined to comment.
