U.S. Treasury Investigates Crypto Platforms for Sanctions Evasion by Iran

In a significant move, the U.S. Treasury Department is probing whether cryptocurrency platforms have been instrumental in helping Iranian officials evade Western-imposed sanctions. Ari Redbord, global head of policy at blockchain analytics firm TRM Labs, revealed this development in an interview with CoinDesk, highlighting a shift in enforcement focus from individual digital wallets to the broader crypto infrastructure.

Redbord emphasized that the concern extends beyond isolated wallet activities. “The activity appears concentrated through exchange-linked systems that function as repeatable financial access points for sanctioned networks,” he stated. This shift in focus underscores the complexities of tracking illicit financial activities in the rapidly evolving digital currency landscape.

Iran’s Growing Crypto Footprint

The investigation comes amid rising alarm in Washington over Iran’s burgeoning use of digital assets. According to TRM Labs and Chainalysis, Iran’s crypto transaction volumes soared to an estimated $8–10 billion last year, with both state-linked entities and everyday users increasingly turning to cryptocurrencies as a means of financial survival amid crippling sanctions.

One notable example identified by TRM Labs is Zedcex, a cryptocurrency exchange allegedly controlled by Iran’s Islamic Revolutionary Guard Corps (IRGC). The exchange reportedly processed around $1 billion in funds linked to the IRGC, which accounted for approximately 56% of its total transaction volume, peaking at 87% in 2024. “This is direct evidence of a nation-state actor turning not to laundering crypto proceeds through a series of wallet addresses, but to using crypto infrastructure,” Redbord noted.

Sanctions Targeting Crypto Exchanges

In a decisive action last week, the U.S. Treasury Department sanctioned Zedcex and another exchange, Zedxion, for their roles in facilitating transactions within Iran’s financial sector. The Office of Foreign Assets Control (OFAC) stated that these exchanges have been instrumental in supporting the IRGC, which is designated as a terrorist organization by the U.S. and its allies. Since their registration in 2022, Zedcex alone has processed over $94 billion in transactions.

The sanctions come in the wake of the United Nations reinstating sanctions on Iran in 2025, particularly concerning its nuclear program. This trend is not unique to Iran; other nations under U.S. sanctions have also turned to cryptocurrencies to circumvent restrictions, with Chainalysis reporting that U.S.-sanctioned countries received nearly $16 billion in digital assets last year.

The Dual Nature of Crypto in Iran

While TRM Labs estimates that half of Iran’s crypto volumes are linked to the IRGC, they also highlight that many transactions originate from retail users. Ordinary Iranians are increasingly relying on cryptocurrencies to preserve their savings and maintain access to the global financial system as the Iranian rial continues to weaken.

“For most people in Iran, crypto remains primarily about access,” Redbord explained. However, he cautioned that the situation changes when state-linked actors begin to rely on crypto-native infrastructure designed to sustain sanctioned finance at scale.

Challenges in Sanctions Enforcement

The pseudonymous nature of cryptocurrency wallets poses significant challenges for sanctions enforcement. Redbord pointed out that by the time an address is sanctioned, it often has little operational value. “Rebuilding functioning financial infrastructure is much harder,” he said, emphasizing the need for a strategic approach that disrupts liquidity and access rather than targeting individual wallets.

As blockchain networks evolve into essential payment and settlement rails, Redbord predicts that their use by sanctioned states will continue to adapt. “Lawful usage will continue to dominate,” he stated, “but sophisticated state actors and professional sanctions evaders will increasingly operate through specialized infrastructure built on top of those same rails.”

As the U.S. Treasury intensifies its scrutiny of cryptocurrency platforms, the implications for global finance and sanctions enforcement are profound, marking a pivotal moment in the intersection of digital assets and international relations.
