币界网报道：Iranian authorities have launched an investigation into alleged money laundering involving the country's largest crypto exchange Nobitex, following reports of a $3.4 million hack in 2022. The exchange claims it was unaware of any illicit activity and maintains it has complied with all regulations. The case highlights growing regulatory scrutiny of crypto platforms in Iran, where digital assets have become increasingly popular amid economic sanctions. Nobitex, which processes over $200 million in monthly trading volume, says it has implemented stricter KYC measures since the incident. The investigation comes as Iran seeks to formalize its crypto framework, with officials recently proposing new licensing requirements for exchanges. Analysts note the case could set important precedents for crypto oversight in the sanctioned nation.
