As crypto crime grows more sophisticated, the weakest point in blockchain investigations is no longer transparency — it’s fragmentation.
—
Funds don’t stay on one chain. They hop across bridges, split into multiple paths, and move through increasingly complex laundering workflows designed to overwhelm traditional monitoring tools. This is the problem SynapTrack is built to solve.
This week, Nimiq and researchers from the University of Birmingham unveiled SynapTrack, a next-generation AML and investigation framework designed specifically to trace illicit activity across chains, not just within them.
The first working version was presented in London on February 25 at CyberASAP Demo Day and is now open to developers, researchers, and the broader crypto community for evaluation and collaboration.

Why Cross-Chain Is the Hard Part
Public blockchains are transparent by design. The challenge emerges when funds move between networks.
Bridges, mixers, and multi-chain dispersal strategies allow attackers to obscure origin and ownership, creating analysis blind spots that legacy AML tools struggle to handle. SynapTrack is designed for exactly these scenarios, using blockchain-aware pattern analysis to follow illicit flows even as they fracture across chains.
Rather than relying on static rules, the system adapts. Its detection logic continuously updates as new laundering tactics emerge, allowing investigators to keep pace with adversaries who actively change behavior to evade tracking.
Fewer Alerts, Better Signals
One of the biggest operational bottlenecks in blockchain investigations isn’t a lack of data — it’s too much noise.
Many monitoring systems flag large volumes of suspicious activity that later turn out to be benign, forcing analysts to manually review alerts at scale. SynapTrack aims to reverse that dynamic by dramatically reducing false positives, allowing investigators to focus on high-confidence leads.
In early testing using real-world data from the 2025 Bybit hack — where attackers stole roughly $1.5 billion in digital assets — SynapTrack traced illicit activity with a false positive rate below 2%. That signal-to-noise improvement is what turns tracing from an academic exercise into a practical investigative tool.

Research-Led, Production-Minded
SynapTrack originated from academic research led by Dr. Pascal Berrang and PhD researcher Endong Liu at the University of Birmingham, with Nimiq contributing implementation expertise and real-world blockchain constraints.
This collaboration reflects a deliberate approach: research first, engineering second, deployment third. Nimiq has a long track record of working closely with academic teams to translate theory into systems that can actually operate in live blockchain environments.
According to Nimiq’s Max Burger, SynapTrack represents the first tangible milestone in a broader effort to make blockchain investigations more scalable as transaction volume and laundering complexity continue to increase.
Dr. Berrang framed the motivation more bluntly: blockchain transactions are growing at near-exponential rates, and while most activity is legitimate, speed and jurisdictional reach make blockchains attractive to criminals. Effective regulation and enforcement depend on tools that can match that scale without sacrificing accuracy.
Opening the System to the Community
Rather than keeping SynapTrack closed, the team is making the framework available to developers, researchers, and investigators for feedback and collaborative improvement. The goal is not just to publish research, but to evolve a system that stays effective as cross-chain activity becomes the norm rather than the exception.
If blockchains are going to support global-scale finance, they also need infrastructure that can handle global-scale compliance and enforcement. SynapTrack is an early signal of what that infrastructure might look like when adaptability, not just transparency, becomes the core design principle.
