The rise of cryptocurrency has brought innovation—and new challenges. As digital assets become more mainstream, so too have crypto-related crimes like scams, fraud, and money laundering. While law enforcement agencies in regions like Taiwan already possess strong investigative capabilities, the technical complexity of blockchain has created a knowledge gap that criminals exploit. However, a powerful shift is underway: through strategic collaboration between exchanges and public authorities, trust is being built, tools are being refined, and investigations are becoming faster and more accurate.
This transformation isn't theoretical—it's happening now, driven by real-world partnerships like those led by XREX, a regulated global blockchain financial institution. By sharing expertise, tools, and insights, they're helping law enforcement overcome technological barriers and redefine how crypto crimes are investigated.
Bridging the Blockchain Knowledge Gap in Law Enforcement
Despite Taiwan’s reputation for elite investigative skills—ranked among the world’s best by experts like Taipei District Prosecutor Hung Min-Chao—blockchain initially posed a significant hurdle. Traditional methods of tracking illicit funds fell short when dealing with decentralized wallets and pseudonymous transactions.

The core issue? A lack of familiarity with blockchain mechanics across many frontline officers and legal teams. This knowledge gap meant that even when victims reported crypto fraud, authorities often struggled to trace funds or identify responsible parties quickly. Worse, compliant platforms were sometimes mistakenly viewed as complicit simply because their wallets appeared in transaction trails.
To close this gap, XREX launched an ongoing educational initiative, conducting practical training sessions for agencies including the Investigation Bureau, prosecutors’ offices, and local police departments. These workshops focus on crypto flow tracking, teaching investigators how to interpret wallet activities, recognize red flags, and distinguish legitimate platforms from fraudulent ones.
As a result, law enforcement has evolved from reactive inquiry to proactive analysis—no longer treating all exchanges the same but instead understanding the nuances of different business models and technical infrastructures.
Two Key Breakthroughs in Crypto Crime Investigation
1. Automated Data Access with Smart Tools Like XRAY
Previously, investigators had to manually contact multiple exchanges to determine whether a suspicious wallet belonged to any of them. This process was inefficient—time-consuming for both law enforcement and compliant platforms—and often yielded no useful results.
XREX addressed this bottleneck by developing XRAY, an internal blockchain wallet address lookup tool now shared with law enforcement. With XRAY, agents can input any wallet address and instantly receive critical information:
- Which exchange (if any) the wallet is associated with
- Asset types and total balances
- Risk indicators based on transaction history
Think of it as an "X-ray" for blockchain activity—offering immediate visibility into otherwise opaque data.
According to Lin Chien-Lung, Director of the Cybercrime Prevention Center at the Criminal Investigation Bureau, XRAY significantly improves preliminary assessments: "If the wallet belongs to a specific exchange, seeing its name right away helps direct the investigation efficiently."
Since June 2024, XRAY has also been available to the public via a free LINE bot service, empowering individuals to check wallet risks before transacting.

This automation reduces redundant requests by up to 90%, freeing up resources for actual investigations and ensuring faster responses during time-sensitive cases.
2. Understanding Business Models to Target Real Threats
Technology alone isn’t enough. Investigators must also understand the ecosystem they’re policing. Without context, even well-intentioned efforts can misfire—like targeting a compliant exchange simply because criminals used it to cash out stolen funds.
Through repeated collaboration and case reviews, law enforcement now better understands distinctions between:
- Legitimate exchanges with KYC/AML protocols
- Unregulated peer-to-peer traders
- Fake investment platforms designed solely for fraud
They can analyze token contracts, assess project legitimacy, and trace fund movements with greater precision. For example, if a scammer uses a reputable exchange to convert illicit USDT into fiat, investigators now know the exchange isn’t the perpetrator—but a victim of abuse.
As Miffy Chen, Blockchain Financial Crime Investigator at XREX, explains: "It’s like investigating money laundering—you need to know which bank account belongs to which institution. Otherwise, your entire strategy could be off target."
This shift allows authorities to focus investigative energy where it matters most: on actual criminal operations, not cooperative financial intermediaries.
The Fruit of Trust: Stronger Policies and Smarter Prevention
Beyond individual cases, the most profound outcome of this public-private partnership is mutual trust. What began as isolated training sessions has grown into a continuous feedback loop that benefits both regulators and industry players.
Impact 1: Real-Time Intelligence Sharing
Both exchanges and law enforcement receive thousands of fraud reports daily. When these insights are siloed, opportunities are missed. But when shared securely and promptly, patterns emerge faster.
With established trust, XREX now engages in timely intelligence exchanges with agencies—flagging emerging scams, suspicious clusters of wallets, or new phishing tactics. This enables vertical and horizontal integration of risk data, enhancing prevention across the board.
Impact 2: Influencing Policy from the Frontlines
Trust also opens doors to policy discussions. XREX executives and security experts have participated in high-level consultations on proposed legislation such as Taiwan’s "New Four Anti-Fraud Laws", which aim to regulate crypto under expanded anti-money laundering (AML) and surveillance frameworks.
By contributing real-world operational insights, XREX helps shape regulations that are both effective and fair—avoiding overreach while strengthening consumer protection.
Frequently Asked Questions (FAQ)
Q: What is XRAY, and who can use it?
A: XRAY is a blockchain wallet query tool developed by XREX that identifies exchange affiliations, asset details, and risk profiles of wallet addresses. It's used by law enforcement and is available to the public via a free LINE bot.
Q: Can blockchain transactions really be traced?
A: Yes. While blockchain offers pseudonymity, every transaction is recorded publicly. With the right tools and expertise, investigators can follow fund flows and link addresses to real-world entities.
Q: Are cryptocurrency exchanges helping law enforcement?
A: Leading regulated exchanges like XREX actively collaborate with authorities through training, tool-sharing, and intelligence exchange to combat financial crime.
Q: How does public-private cooperation improve fraud prevention?
A: It accelerates investigations, reduces false accusations against compliant platforms, enables faster response to emerging threats, and leads to smarter regulation.
Q: Is my data safe if I use tools like XRAY?
A: Yes. XRAY only analyzes publicly available blockchain data. No personal information is collected unless voluntarily submitted for advanced services.
Q: What role do blockchain financial crime investigators play?
A: They act as bridges between technical blockchain data and legal investigation processes—translating complex on-chain activity into actionable intelligence for law enforcement.
Through sustained cooperation, education, and innovation, the fight against crypto crime is entering a new era. No longer hindered by technical ignorance or institutional distrust, investigators are now equipped to follow the money—wherever it flows on the blockchain.
