Crypto laundering isn’t slowing down—it’s scaling up. As criminals exploit bridges, swaps, and smart contracts to move funds across chains at lightning speed, investigators are left chasing fragmented trails and partial data. In this blog, we’ll explore how Merkle Science’s Tracker enables real-time, automated cross-chain tracing to help law enforcement and intelligence teams to keep up. You'll learn how Tracker decodes cross-chain transactions, automates asset identification, and provides full forensic visibility.
In the early days of crypto crime, laundering meant hopping between wallets or using mixers. But as law enforcement caught up, criminals evolved. Today, they rely on:
By the time funds exit a laundering pipeline, they may have crossed multiple blockchains, changed formats, and interacted with hundreds of smart contracts.
For investigators, that means partial transaction histories, unlinked chains, and major blind spots.
Most blockchain investigation tools weren’t built for today’s fast-moving, multi-chain laundering. While many support multiple blockchains, they often struggle to connect activity across them without delay. Investigators face:
This leads to partial visibility, slower investigations, and weaker attribution..
With Tracker, Merkle Science provides the most advanced cross-chain tracing capability on the market. Here's what it brings to the table:
Whether criminals use mainstream bridges like Stargate and Synapse, or more obscure DeFi protocols, Tracker identifies the route and ensures no movement is missed.
Instant access to bridged transactions ensures investigators always work with the most current data—accelerating response times and eliminating sync delays.
Wrapped tokens and bridged assets can disguise the real movement of value. Tracker automatically detects and labels:
This removes guesswork—and reveals when routine-looking transactions are actually laundering attempts.
High-volume transactions often bury the flow you care about. That’s why Tracker includes advanced filtering options, so investigators can instantly narrow down:
This allows teams to cut through the noise and focus on high-risk flows immediately.
With direct links to public bridge explorers, investigators can verify transactions in real time—building clear, reproducible evidence that holds up in legal proceedings.
Many wallets that interact with bridges don’t appear in public explorers. Tracker maintains a database of over 6,000 bridge-related addresses—including ones not visible through other tools—giving investigators deeper insights into wallet roles, connections, and exposure.
When criminals fragment their laundering activity across multiple chains, investigators need a way to stitch the story back together. With Tracker’s unified investigation environment, teams can:

The pace of cross-chain laundering is only increasing. Without the ability to follow funds in real time, across multiple chains and formats, even experienced investigators risk being left behind.
Tracker solves this by automating the hardest parts of the process—so you can stay focused on what matters: catching criminals, recovering assets, and closing cases.
