A Dubai-based exchange tied to Iran sent Binance cryptocurrency worth 676 million dollars, according to a Reuters investigation reported by Unchained. The exchange, according to sources, operated without a license.

Blockchain analysts traced through this venue no less than 4 billion dollars. The source also notes that it provided access to global crypto markets to the Central Bank of Iran and a network of 2 000 gaming sites.

The scale of the operation makes the story significant for questions of sanctions compliance, crypto exchange licensing, and due diligence of counterparties. However, the original package lacks the full text of the investigation, details on the period of transfers, the legal status of participants, or Binance’s and other named parties’ positions.
