US Treasury Secretary Scott Bessent revealed sanctions this week against a network of Bitcoin wallets associated with Iran, resulting in the freezing of $344 million in cryptocurrency. This represents one of the most significant enforcement actions aimed at Tehran’s on-chain infrastructure.
Under Economic Fury, @USTreasury will persist in systematically undermining Tehran’s capacity to generate, transfer, and repatriate funds.

This action coincides with the Trump administration intensifying economic pressure on Iran amid ongoing nuclear negotiations, indicating that the Treasury is no longer viewing cryptocurrency as a secondary issue in sanctions enforcement.
Last year, Iran’s cryptocurrency ecosystem was valued at over $7.78 billion, expanding more rapidly than in 2024, with the Islamic Revolutionary Guard Corps now responsible for half of all on-chain activities.

According to Chainalysis, Iran’s crypto economy reached approximately $7.78 billion in 2025 — an increase from the previous year as Bitcoin withdrawals surged during nationwide protests and an internet blackout.

How Iran Turned USDT and State Bitcoin Mining Into a Sanctions Bypass Machine
The Central Bank of Iran acquired over $500 million in USDT last year, allegedly and systematically channeling reserves through a US dollar-pegged stablecoin to evade SWIFT-dependent banking systems. Elliptic highlighted these purchases in a January report, describing it as part of a calculated strategy to access dollar liquidity without engaging with the correspondent banking framework.

USDT’s attractiveness is structural. It provides dollar stability without the necessity of a US bank account, settles on public blockchains within minutes, and can be transferred freely across borders. Iran has been leveraging this opportunity extensively.
Geopolitical tensions, such as the Strait of Hormuz dispute, have further accelerated this integration: in early April, Iranian officials declared that oil vessels passing through the strait would be required to pay tolls in bitcoin, formalizing the role of cryptocurrency in sovereign trade infrastructure.

The IRGC’s parallel operations are more challenging to trace. Utilizing subsidized electricity, the IRGC engages in cryptocurrency mining, effectively converting energy into non-sanctionable funds, according to a cryptocurrency and blockchain researcher based in Tehran.
Freshly mined Bitcoin has no transaction history; it is devoid of any address exposure that on-chain analytics firms can identify. This makes it significantly more advantageous than coins circulating through sanctioned exchanges, allowing the IRGC to generate hard currency from energy resources that cannot be retroactively frozen by enforcement actions.

OFAC linked the frozen $344 million directly to USDT wallets involved in Iran’s oil payment masking operations, with Tether blacklisting the identified addresses.
“We will track the funds that Tehran is urgently trying to move outside of the country and target all financial lifelines associated with the regime,” Bessent posted on X.
However, the gaps remain evident in the transaction data. Between February 28 and March 2, following US-Israel strikes, on-chain analytics detected $10.3 million in cryptoasset outflows from Iran-linked Bitcoin wallets. Chainalysis confirmed that some of these wallets had historical connections to IRGC-identified addresses, indicating real-time state-level fund movement.
Prior to Israel’s 12-day conflict in June 2025, TRM Labs noted a 150 percent increase in outflows from Nobitex. Within minutes of the initial strike, outgoing volumes surged by 700 percent. Even when $90 million was stolen from Nobitex in a June 18 cyberattack attributed to the Israel-linked group Predatory Sparrow, the platform’s 11 million users continued trading. The ecosystem absorbed the impact.
Martin stated that regulators “are beginning to recognize” that cryptocurrencies are being utilized extensively for sanctions evasion, and additional designations are forthcoming. If the Treasury aligns its next series of actions with the DOJ and FinCEN to target virtual asset service providers handling Iranian transactions, and pressures stablecoin issuers to adopt proactive blocking measures rather than reactive blacklisting.
