Chinese Police Published Methods to Track and Seize Cryptocurrency on June 4

According to South China Morning Post, Chinese police officials published a technical paper on June 4 detailing methods to track and seize cryptocurrency used in crimes. The paper, authored by officers from Wenzhou Public Security Bureau and Zhejiang Provincial Police, appeared in the academic journal Criminal Technique.

The report outlines a three-stage process: locating private keys and mnemonic phrases stored on suspects' devices using forensic software; tracing fund flows across blockchains by analyzing transaction fees and exchange records; and transferring seized assets to multi-signature wallets under police control or freezing exchange accounts. The paper emphasizes internal oversight mechanisms to prevent misuse by investigators.
