A WeChat article urges blockchain tracing of scam-linked on-chain flows and an evidence model centered on domestic collection, with cross-border support and clearer judicial-assistance boundaries.
Chinese prosecutors said virtual currency wallet addresses should be treated as the entry point for crypto money laundering investigations, with blockchain analysis used to trace on-chain fund flows and scam-related transfers. In a WeChat article, they outlined an evidence framework built around domestic collection and reinforced by cross-border evidence, reflecting the practical challenge of investigating transactions that can move across multiple jurisdictions and service providers. The article also called for identifying laundering methods involving crypto while clarifying identity and transaction links, as well as the boundary between unilateral evidence collection and bilateral judicial assistance. It earlier urged standardized requests to exchanges, wallet providers and payment channels for KYC (customer identity checks), login, device, IP, 2FA (two-factor authentication), deposit and withdrawal, address, transaction hash, risk-control and freeze records. The approach points to a more structured investigative model for tying blockchain activity to identifiable users and preserving evidence in cases where digital assets pass through both on-chain and off-chain services.
