Investigators at Binance have uncovered approximately $1.7 billion in crypto transactions allegedly flowing to Iranian-linked groups, raising fresh compliance and sanctions concerns. The findings emerged from an internal probe examining historical transaction data and blockchain activity tied to entities suspected of operating under U.S. sanctions. The exchange said it has strengthened monitoring systems and cooperated with authorities to address potential violations. The revelation underscores ongoing challenges for global crypto platforms in enforcing sanctions, tracking illicit flows, and maintaining regulatory compliance across jurisdictions.
