The Istanbul Chief Public Prosecutor’s Office announced Monday that authorities had frozen the assets of Seref Yazici, owner of the cryptocurrency platform Darkex, as part of a widening investigation into illegal betting and crypto-linked money laundering.
Darkex is known as a Dubai-based cryptocurrency trading platform that was operating in Türkiye without a license and has been blocked by the Capital Markets Board (SPK) since September 2025.
According to MASAK, Türkiye’s Financial Crimes Investigation Board, Yazici is accused of securing illicit profits by providing digital infrastructure for unauthorized betting platforms through the exchange.
To prevent the laundering of assets believed to be acquired through criminal activity, authorities have frozen a wide range of Yazici’s holdings, including real estate, corporate shares, and accounts at both traditional banks and cryptocurrency exchanges.
The development follows an earlier seizure of $550 million in crypto assets linked to fugitive Veysel Sahin last week, who is wanted under an Interpol Red Notice on charges of operating illegal betting platforms and laundering criminal proceeds.
Extradition proceedings are currently underway.
