Coin Center's Peter Van Valkenburgh says the U.S. Treasury's new Iran digital-assets sanctions determination should not be read as an automatic ban on decentralized infrastructure.

Treasury this week launched Operation Economic Outcast and named digital assets as one of several Iranian economic sectors exposed to additional sanctions risk. OFAC also published Iran-related designations and general license updates tied to the same campaign. The practical effect is broader enforcement authority against foreign persons that operate in, or provide material support to, covered Iranian sectors.

The open question is how that language applies to neutral crypto infrastructure. Unchained reported that Van Valkenburgh, Coin Center's research director, said the release does not designate any particular protocol and does not directly answer whether running nodes, mining, developing software, or supporting DeFi tools counts as operating in Iran's digital-asset sector.

That distinction matters because sanctions compliance is straightforward for many custodial businesses but harder for open networks where software, validators, relayers, and liquidity protocols can be used by people across jurisdictions. Treating all infrastructure as covered activity would have a much wider effect than targeting named wallets, exchanges, or counterparties.

The conservative read is that Treasury has expanded the risk surface, not settled every boundary. Crypto firms with custody, routing, analytics, or payment exposure now have a clearer reason to revisit Iran controls, while protocol developers and infrastructure operators still face uncertainty over how OFAC will apply the determination in practice.
