Summary

Siavash Kayvanpour is an Iranian expatriate and founder of Shelbit, an unlicensed cryptocurrency exchange that U.S. Treasury's OFAC personally designated on August 7, 2026 under Executive Order 13224 for materially supporting Iran's Islamic Revolutionary Guard Corps (IRGC). Blockchain investigators traced over USD 6.3 billion in flows through the Shelbit network between May 2024 and March 2026, linking the exchange to IRGC-affiliated wallets, Iran's central bank, and one of the world's largest illegal online gambling operations. Kayvanpour holds citizenships in Iran, Dominica, and Afghanistan, complicating international enforcement of the designation.
