When OFAC sanctions landed on four Iranian exchanges on June 2, 2026, they captured most of the country’s on-chain economy but not all of it. TRM Labs attributed $7.7 billion of 2025 volume to Nobitex, Wallex, Bitpin and Ramzinex combined — 78% of Iran’s $9.9 billion total. The August 7 action reads as a deliberate move on the remaining fifth, and on the corporate plumbing that absorbed the displaced flow.
The second detail the headlines missed: this was not simply “two exchanges.” OFAC designated seven persons, and six of them went out under Executive Order 13224, the counter-terrorism authority, not the Iran financial-sector authority. Compliance teams that file this under an Iran playbook will mis-classify most of the list.
What OFAC actually designated
Per the Treasury announcement, the network centres on Siavash Kayvanpour, born in Iran, holding additional citizenship from Dominica and Afghanistan, and resident in the United Arab Emirates. Through Republic of Georgia-registered SHPS Shelbit he operates Shelbit Exchange. Digital currency addresses belonging to the Islamic Revolutionary Guard Corps (IRGC) sent the equivalent of more than $1 million to Shelbit Exchange addresses, and more than $2 million moved back the other way. Addresses controlled by Kayvanpour sent over $2 million to already-designated Nobitex.
Kayvanpour, SHPS Shelbit, UAE-based Shelbit General Trading LLC, Poland-based Shelbit Technologies Ltd — now in liquidation — plus Crypto Home DMCC and NFT Home DMCC were all designated under E.O. 13224, as amended, carrying secondary sanctions risk under section 1(b) as amended by E.O. 13886. Only Aban Tether Exchange, a Tehran-based venue with no connection to stablecoin issuer Tether Limited, was designated under E.O. 13902 for operating in the financial sector of the Iranian economy. It had processed millions of dollars of transactions with Nobitex, Wallex, Bitpin and Ramzinex.
Fourteen addresses, five chains
The SDN List update carries 14 digital currency addresses — six tied to SHPS Shelbit, four to Crypto Home DMCC and four to Kayvanpour personally. They span Bitcoin, Ethereum, Tron, BNB Chain and Solana. Screening stacks scoped to the Bitcoin, Ethereum and Tron triad that TRM identified as the Iranian norm will silently miss the BNB and Solana legs. Two of the Bitcoin entries are bech32 addresses, which some legacy list-ingestion tooling still normalises incorrectly.
The most instructive fact for counterparty risk sits in a single Treasury sentence. Dubai’s Virtual Assets Regulatory Authority issued enforcement actions against Shelbit General Trading in January 2025 and again in July 2026 — and Treasury notes the entity “remains in business.” Nineteen months of action from the licensing regulator did not close it. One designation did. That is a direct rebuttal to treating a UAE licence as counterparty comfort, and it sharpens the supervisory gap covered in Dubai’s two-regulator problem.
Gambling rails and the response
Treasury also says Shelbit serviced a large Persian-language gambling network run by two Iranian influencers, laundering tens of millions of dollars of that network’s assets. Both were convicted of illegal gambling in Iran in 2023, yet their sites retain access to Iran’s online payment systems, which the Central Bank of Iran tightly regulates.
“The Iranian regime’s reliance on digital assets and shadow banking networks is further evidence that Economic Fury is working,” said Scott Bessent, Secretary of the Treasury. “We will continue to increase the economic pressure. Whether in dollars, rials, or crypto, Treasury will hunt down and dismantle the illicit financial networks that keep the regime afloat.”
Enforcement is compounding. Chainalysis recorded Tether freezing $131 million in stablecoins across Iranian central bank-linked wallets after OFAC’s July 2026 designation — issuer-level action no screening vendor can replicate. This action was developed with IRS-Criminal Investigation; OFAC also amended FAQ 1257 the same day.
What this means for venues
The operative risk is the 50% rule: any entity owned half or more, individually or in aggregate, by these blocked persons is itself blocked without appearing on the list. A network built across Georgia, Poland, the UAE and Iran is designed to make that ownership opaque. Exchanges that offboarded Nobitex in June inherited counterparties that routed through Shelbit; those relationships now require re-screening against corporate registry data, not just wallet lists.
Expect the same displacement mechanic to repeat. Each designation pushes volume toward smaller, less-instrumented venues, which is exactly how a Tbilisi-registered exchange with a Warsaw subsidiary ended up on an IRGC list. Behavioural evasion is already visible elsewhere — HTX’s wallet rotation against UK screening shows how fast address-based controls decay. The structural answer runs through counterparty attribution and the FATF Travel Rule’s uneven implementation, while the legal boundaries of what can be sanctioned remain contested across the US, EU and UK — a gap Nobitex has exploited since its $90 million hack.
