Treasury Sanctions Iranian Exchange BitBank Over IRGC Bitcoin Network

Washington Targets the Infrastructure, Not Just the Wallets

The U.S. Treasury’s Office of Foreign Assets Control has designated Iranian digital asset exchange BitBank as part of a sanctions-evasion network tied to Iranian financier Babak Zanjani. The designation, published through the OFAC press release system, also covers BitBank’s developer – Pishtaz Simorgh Electronic Trade Company – along with several individuals operating within Zanjani’s broader business network. Treasury’s allegation is specific: between June and July, Zanjani used BitBank to move hundreds of millions of dollars in Bitcoin to Iran’s Islamic Revolutionary Guard Corps. These are designations under U.S. sanctions law, not criminal convictions.

What separates this action from a standard wallet blacklisting is its scope.

Rather than flagging a cluster of addresses or tracing a single transaction chain, OFAC went after an operating exchange and the software company that built it. That distinction matters because it signals something about how Treasury views crypto infrastructure when it believes that infrastructure is being used to route money around sanctions regimes. BitBank was not incidental to the alleged network – according to Treasury, it was the mechanism.

Why Sanctioning a Platform Is Different From Sanctioning an Address

OFAC has a long history of designating individuals, banks, and front companies suspected of helping sanctioned actors access international financial systems. The move against BitBank fits that pattern but extends it into territory that crypto compliance teams have been watching closely. When Treasury sanctions a company rather than a wallet, every exchange, payment processor, and institutional trading desk with U.S. exposure faces an immediate screening obligation – not just for BitBank’s known addresses, but for any counterparty that touched its infrastructure.

Previous OFAC enforcement rounds against Iran-linked financial networks targeted banks, money service businesses, and occasional crypto facilitators. BitBank’s designation puts a full digital asset exchange – with its own developer entity – in that same category. The inclusion of Pishtaz Simorgh Electronic Trade Company is particularly notable. Software companies building exchange infrastructure have not always been the primary target of sanctions actions, but designating the builder alongside the platform sends a clear message about where Treasury believes legal exposure begins.

In previous enforcement actions, OFAC targeted exchanges, banks, and individual facilitators it said helped sanctioned actors move money outside conventional banking channels. BitBank’s designation escalates that approach by treating an operational crypto business and its technical developer as entities equivalent to a financial institution – subject to the same prohibitions that apply when Treasury believes a bank is being used as a conduit for sanctioned funds.

What the Designation Means for Compliance Operations Globally

The practical consequences of an OFAC designation move fast. Once an entity lands on the Specially Designated Nationals list, U.S. persons are prohibited from transacting with it. More broadly, compliance systems at exchanges and financial institutions worldwide begin screening for connected addresses, related entities, and counterparties that interacted with the designated business. A Treasury announcement that takes minutes to publish can take weeks for compliance teams to fully unwind across transaction histories and counterparty exposure.

The crypto industry has spent years building blockchain analytics tools and wallet-screening systems – partly in anticipation of situations like this one. Public ledgers make Bitcoin movements traceable in ways that physical cash rarely allows, but that traceability does not automatically satisfy sanctions obligations. Knowing where funds went is different from having systems in place that flag, freeze, or refuse those funds before the transaction clears. Treasury’s action against BitBank reflects an expectation that exchanges treat digital asset sanctions exposure the same way a bank treats wire transfer compliance.

The IRGC connection raises the stakes further. The IRGC has been designated a foreign terrorist organization by the U.S. government, meaning transactions that help fund it carry potential exposure under both sanctions law and counterterrorism financing statutes. If Treasury’s allegations hold – that hundreds of millions in Bitcoin moved through BitBank to the IRGC – the designation is not just a compliance event for the crypto industry but a data point in the ongoing argument about whether decentralized financial infrastructure can be adequately regulated when state actors are the counterparty.

For compliance officers at exchanges operating anywhere near Iranian counterparty risk, the BitBank action adds another named entity to screen against – but the broader pressure it creates is structural. Treasury is not asking the crypto industry to be more careful. It is demonstrating, through enforcement, that it holds crypto businesses to the same standard as any other financial institution suspected of running money for a sanctioned government’s military wing. Whether BitBank’s specific technical architecture made that allegedly possible – or whether similar infrastructure exists elsewhere – is a question OFAC’s next designation may answer.
