Iran’s crypto market just went cold. Not collapsed. Cold. And the difference matters.
Transaction volume fell roughly 80% between February 27 and March 1, according to TRM Labs. The timing lines up directly with US-Israeli airstrikes beginning on February 28. Internet connectivity inside Iran reportedly dropped by about 99% as the regime rolled out restrictions shortly after the conflict escalated.

Retail users lost access. Market makers lost API connections. Automated systems disconnected entirely. Iran’s largest exchange, Nobitex, recorded an increase of nearly $3 million USD in flows on February 28 compared to the day before. TRM analysts identified the movement as an internal hot-to-cold wallet transfer on Polygon. A separate cold storage move of over USD 35 million also came from Nobitex that day.
Exchanges Shut the Door on Withdrawals
TRM assessed both transactions as falling within the normal range of operational activity. Capital flight? Not yet. Not from the data.
Still, every major domestic exchange moved into some version of lockdown. Bitpin issued risk guidance pushing users away from emotionally driven trading. Wallex suspended crypto withdrawals entirely, citing infrastructure instability. Aban Tether halted both crypto and rial withdrawals outright. Ramzinex suspended deposits and withdrawals while telling users their assets sat secured in cold wallets. Tabdeal switched to twice-daily batch processing, warning of delays up to 24 hours.

Nobitex said deposits and withdrawals remained available “to the extent possible.” That wording signals something. It’s not a clean green light.
Iranian exchange Wallex attributed its platform outage to a power disruption at the Asiatech data center, per the TRM Labs report. That same infrastructure appears in Nobitex’s own source code as part of its hosting environment. Two of Iran’s biggest exchanges sharing physical infrastructure. That’s the kind of single-point exposure that gets stress-tested during a conflict.
The USDT-Toman Pair Just Disappeared Overnight
Then came the central bank directive.
Nobitex, Wallex, Bitcoin, and Tabdeal all announced they were halting the USDT-toman trading pair under orders from Iran’s Central Bank, as detailed by TRM Labs. That pair is the primary crypto-to-fiat bridge in Iran. Dollar-linked stablecoins bought and sold against the rial. The most systemically sensitive pair in the entire domestic market.

Canceling open orders mid-session, pausing the primary bridge pair overnight. The move effectively slowed fiat repricing during peak volatility. When trading on the USDT-toman pair resumed, thin order books showed up immediately. Nobitex cited supply-demand imbalance and reversed certain liquidations. Bitpin reported a brief pricing anomaly and committed to compensating affected users. Tabdeal activated internal risk controls and insurance mechanisms.
Not failure. Stress. There’s a gap between those two things.
Iran Processed $11 Billion in Crypto This Year
The context here is easy to miss if you’re watching the freeze and not the base size.
TRM has tracked approximately USD 11 billion in total crypto activity linked to Iran from January 2025 to present. Nobitex alone processed volumes around $5 billion in that same window. The Iranian crypto economy is not a fringe market. It is one of the larger crypto markets in the world by volume.

TRM notes separately that state-linked actors could use available crypto infrastructure to reposition capital during a liquidity freeze. The firm flagged the earlier case of Zedcex, a UK-registered exchange later sanctioned by the US Treasury, which processed stablecoin flows linked to Iran’s Islamic Revolutionary Guard Corps. That precedent matters now. Distinguishing opportunistic regime repositioning from the broader market contraction requires deeper transactional analysis than aggregate flow trends can show.
What happens next depends on two things: whether internet access stabilizes inside Iran, and whether the conflict continues escalating or pulls back. Both remain open questions.
