According to an investigation by *Nikkei*, a China-based fentanyl precursor chemical supply network was found to have financial links to cryptocurrency scams and money-laundering activities. The investigation shows that during the network’s operation through a Japan-related company, Firsky, there were more than 120 cryptocurrency transactions involving addresses linked to multiple financial scam groups and U.S. sanctioned targets. Among them, a fake token project called “zksync jp” is suspected of using the name of the Ethereum Layer 2 network ZKsync to carry out fraud, resulting in losses of hundreds of millions of yen.
