Chinese police have disclosed details of their evidence collection process for tracking and freezing cryptocurrency linked to suspected criminal activity, offering a rare look at how law enforcement in China builds digital forensic cases involving blockchain-based assets.

Chinese Police Reveal Crypto Evidence Collection Process for Tracking and Freezing Funds

What Chinese Police Actually Disclosed

A rare paper reviewed by the South China Morning Post revealed the forensic tools and procedures Chinese investigators use to trace cryptocurrency transactions and seize digital assets. The disclosure is notable because Chinese authorities have historically kept enforcement methodologies confidential.

The published process covers the full chain from identifying suspect wallet addresses to documenting transaction flows in a format suitable for criminal prosecution. Formal disclosure of these methods signals that Chinese law enforcement views crypto-related crime as a mature enforcement priority, not a fringe concern.

China has maintained a broad ban on cryptocurrency trading since 2021, but criminal cases involving digital assets continue to surface. Incidents like a Chinese man killed in Cambodia after a $2 million crypto extortion attempt underscore the ongoing intersection of crypto and crime in the region.

How Investigators Trace Cryptocurrency Transactions

The disclosed process centers on wallet address identification as the starting point. Investigators map transaction histories from suspect wallets, following fund flows across multiple addresses to build a picture of how assets moved.

Digital evidence collection requires linking on-chain activity to real-world identities. This typically involves connecting wallet addresses to accounts on centralized exchanges, where know-your-customer records can tie transactions to specific individuals.

Documentation quality is critical at every stage. Evidence must meet criminal court standards, meaning investigators need to preserve complete records of how wallet addresses were identified, how transaction paths were traced, and how the connection between on-chain activity and suspects was established.

The process also accounts for counterparty analysis. When funds move between wallets, investigators document relationships between senders and receivers to establish networks of activity rather than isolated transactions.

How the Freezing Process Works in Practice

Asset freezing follows a sequential process: evidence collection, verification of asset ownership, and then a formal freezing action. The disclosed procedure suggests that Chinese authorities treat this as a structured workflow rather than an ad hoc response.

Centralized exchanges and custodial platforms play a key role. When investigators identify suspect funds held on a platform operating within Chinese jurisdiction or cooperating with Chinese authorities, they can request account freezes. This mirrors how Thai police recovered funds in a crypto exchange robbery case through platform cooperation.

Friction points emerge when assets move to self-custodied wallets or cross into services outside Chinese regulatory reach. The disclosed process acknowledges practical limits, particularly when suspects use decentralized protocols or foreign platforms with no obligation to comply with Chinese law enforcement requests.

Timing is another constraint. Cryptocurrency can be moved in minutes, so the gap between evidence collection and freezing action determines whether assets remain recoverable.

What This Means for Exchanges, Users, and Compliance Teams

A formalized evidence collection process creates predictable expectations for exchanges operating in or near Chinese jurisdiction. Platforms may face standardized requests for transaction records, account information, and asset freezes, requiring compliance teams to maintain responsive internal processes.

China’s regulatory framework around digital assets continues to evolve. The Han Kun Law Offices have published analysis of how Chinese legal standards apply to cryptocurrency cases, reflecting growing attention from the legal profession.

For users, the disclosure reinforces that blockchain transparency works in both directions. The same public ledger that allows anyone to verify transactions also gives law enforcement a permanent, searchable record of fund movements. Users holding assets on centralized platforms face the highest exposure to freezing actions.

The formalization also matters beyond China. As countries develop their own crypto enforcement frameworks, including Russia’s upcoming crypto regulatory law, the procedural details disclosed by Chinese police could influence how other jurisdictions structure their own investigative workflows.

Scam operations targeting Chinese users, such as fraud rings operating through Douyin, are likely among the case types driving the need for standardized evidence collection.

FAQ About China’s Crypto Tracking and Freezing Process

Can all cryptocurrency transactions be traced?

Most transactions on public blockchains like Bitcoin and Ethereum are traceable because every transfer is recorded on a permanent, publicly accessible ledger. However, privacy-focused cryptocurrencies and mixing services can make tracing significantly harder, though not impossible with advanced forensic tools.

Can decentralized wallets still face tracking attempts?

Yes. Self-custodied wallets do not require identity verification to create, but transactions to and from those wallets are still visible on-chain. If any wallet in a transaction chain has been linked to a known identity, investigators can potentially trace the flow back to a decentralized wallet holder.

What kind of evidence is needed before assets are frozen?

The disclosed process indicates that investigators must document the connection between suspect criminal activity and specific wallet addresses or exchange accounts before requesting a freeze. This includes transaction records, identity verification data, and evidence linking the assets to the alleged crime.

Does this affect users outside China?

Directly, the process applies within Chinese jurisdiction. However, if funds pass through exchanges or services that cooperate with Chinese authorities, users in other countries could be indirectly affected if their transactions intersect with a Chinese investigation.
