The latest round of Iran crypto sanctions landed on 7 August 2026. The U.S. Treasury’s Office of Foreign Assets Control (OFAC) sanctioned two more crypto exchanges, Shelbit Exchange and Aban Tether. The agency says both helped Iran move money outside the traditional banking system. That money allegedly funded the Islamic Revolutionary Guard Corps (IRGC).
It’s the latest move in a fast-widening crackdown. And it’s worth understanding, even if you’ve never sent a single transaction anywhere near Tehran.

Sanctions news like this looks irrelevant to everyday traders until it touches an exchange, wallet, or stablecoin they actually use.
What was Targeted in OFAC’s Iran Crypto Sanctions?
These Iran crypto sanctions designated Shelbit Exchange.
It operates through a Georgia-registered company controlled by Siavash Kayvanpour.
Kayvanpour is Iranian-born, also holds Dominican and Afghan citizenship, and is based in the UAE.
According to Treasury, IRGC-linked wallets sent over $1 million in crypto to Shelbit. More than $2 million flowed the other way, from Shelbit back to IRGC wallets.
Wallets tied to Kayvanpour also sent over $2 million to Nobitex, Iran’s largest crypto exchange. Nobitex was sanctioned earlier this year, and Aban Tether, an Iran-based exchange, was sanctioned separately. It processed transactions tied to other already-restricted Iranian platforms, including Nobitex, Wallex, Bitpin and Ramzinex.
Despite the name, Aban Tether does not appear to have an affiliation with stablecoin issuer Tether. However, CoinDesk has reached out to Tether to confirm.
The same day, OFAC sanctioned a separate network too.
This one involved foreign exchange houses, shell companies and individuals.
Treasury says the network helped Iran’s shadow banking system move hundreds of millions of dollars, including proceeds tied to overseas oil sales.
“Economic Fury is working,” Treasury Secretary Scott Bessent said.
He framed the action as part of a broader push to squeeze Tehran’s access to dollars, rials and crypto alike.
Iran Crypto Sanctions Timeline: How Did We Get Here?
The Shelbit and Aban Tether designations are not an isolated event. They are the latest entry in a string of Iran-focused crypto sanctions stretching back to the start of the year:
- January 2026: Treasury sanctions Zedcex and Zedxion, the first crypto exchanges ever targeted under Iran-specific financial sanctions.
- June 2026: Nobitex, Iran’s largest crypto exchange, is restricted along with several other Iranian platforms.
- July 2026: Four crypto wallets linked to Iran’s central bank are sanctioned. Tether responds by freezing roughly $131 million held across those wallets. The same month, two Iranian maritime insurance entities are sanctioned over a scheme allegedly funnelling funds to the IRGC.
- August 2026: Shelbit and Aban Tether are on the list, alongside a separate action against an Iran-linked shadow banking network.
The pace is accelerating, and it’s happening against the backdrop of the wider U.S.-Iran conflict.
It has raised the stakes on cutting Tehran off from global financial markets.
8 Things Traders and Investors Should Take From This
You don’t need any exposure to Iran to learn from this. These are risks that show up anywhere crypto, sanctions, and offshore exchanges overlap.
1- Blockchain Transparency Cuts Both Ways
Crypto can offer sanctioned regimes a workaround when banks cut them off. But every transaction leaves a public trail.
That’s exactly how OFAC traced IRGC funds through Shelbit’s wallets.
Investigators followed the on-chain flow from IRGC-linked addresses to Shelbit and back, tracking over $1 million one way and $2 million the other.
This is the opposite of what many people assume.
Cash is genuinely hard to trace once it leaves a bank.
Crypto isn’t.
A public ledger permanently records every wallet-to-wallet transfer, and firms like Chainalysis and TRM Labs specialise in mapping exactly these flows for regulators.
If you have ever assumed crypto is “harder to trace than cash,” this case is a clear example that it’s usually the reverse.
2- Exchange Due Diligence Matters More Than Ever
If you are using smaller or offshore exchanges, check who actually runs them.
Shelbit operated through a Georgia-registered company controlled by a single individual based in the UAE, a jurisdictional spread that’s common among exchanges trying to avoid regulatory attention in any one country.
For example, an exchange might market itself as “EU-regulated” while the entity actually holding customer funds sits in a different, lightly-regulated jurisdiction entirely.
Before depositing funds anywhere unfamiliar, it’s worth checking company registries and ownership disclosures. Also check whether the exchange has ever appeared in enforcement actions, not just whether it has a license somewhere.
3- Sanctioned Wallets Can Freeze Your Funds, Even Indirectly
Tether’s freeze of $131 million linked to Iran’s central bank wallets shows how fast stablecoin issuers move after the designation of an address. That freeze locked the entire balance sitting in those wallets.
This is a realistic version of how this could touch an ordinary trader:
You receive USDT from a counterparty on a P2P platform, unaware that the counterparty’s wallet has previously interacted with a sanctioned address.
Exchanges or issuers can freeze funds downstream. It can sometimes happen with little warning. Plus, there is a slow appeals process to get them unfrozen.
4- Name Similarity Isn’t Affiliation
Aban Tether has no confirmed connection to Tether, the issuer of USDT. The overlap is coincidental (or possibly deliberate branding by the exchange itself), but headlines conflating the two could easily mislead readers into thinking the stablecoin issuer is under sanction.
This matters beyond this one case.
Plenty of platforms borrow the credibility of a recognisable name, “Bitcoin Cash,” “Wrapped Bitcoin,” or exchanges with near-identical names to major players.
Always verify who actually operates a platform rather than assuming a familiar name means a familiar company.
5- “Sanctioned” Lists Compound
Aban Tether wasn’t sanctioned for dealing with Iran directly, but for processing transactions with exchanges, Nobitex, Wallex, Bitpin, and Ramzinex, that were already on the sanctions list.
That’s second-degree exposure, and it was enough on its own to trigger a designation.
This creates a widening radius of risk.
If Exchange A gets sanctioned, and Exchange B has ever processed transactions with Exchange A, Exchange B becomes the next target.
Anyone who used Exchange B, even without ever touching Iran, is now a step removed from a sanctioned network too.
6- This Campaign Is Expanding, Not Slowing
Treasury has sanctioned a new batch of Iran-linked crypto entities roughly every couple of months this year: Zedcex and Zedxion in January, Nobitex in June, four central bank wallets in July, and now Shelbit and Aban Tether in August.
That cadence suggests this isn’t a one-time crackdown but an ongoing campaign.
If you have ever used an Iran-adjacent exchange, or a platform with unclear jurisdictional ties, it’s reasonable to expect further designations rather than assume the list is complete.
7- Gambling and Shadow-Banking Rails Are in Scope Too
Alongside the exchanges, OFAC separately sanctioned a shadow banking network moving oil-sale proceeds. It noted that Shelbit processed tens of millions of dollars for a Persian-language online gambling network.
Sanctions enforcement is not limited to exchanges people think of as “crypto platforms.”
Gambling sites, payment processors, and informal money-transfer networks that happen to touch crypto are equally fair game. It is a good reason not to assume a platform is “safe” just because it doesn’t call itself an exchange.
8- Liquidity and Counterparty Risk Can Appear Overnight
A platform you use today can land on a sanctions list tomorrow, with immediate consequences: frozen withdrawals, locked balances, or sudden delisting by exchanges and wallets that no longer want counterparty exposure.
Traders who kept funds on Nobitex before its June sanctions likely faced exactly this. Sudden restrictions with no warning.
Diversifying which platforms hold your funds isn’t just a compliance nicety. It’s the same logic as not keeping all your savings in one bank.
The Takeaway
You don’t need any connection to Iran for these Iran crypto sanctions to matter. They show how far a sanctions net can reach once wallet-to-wallet crypto flows are in scope.
For traders and investors, the practical lesson is simple: know your exchange, know its wallets, and don’t assume distance from Iran means distance from risk.
