Nominis helped a law enforcement agency uncover a weapons trafficking network that a single wallet screening would never have surfaced. By adding deeper crypto risk intelligence to the investigation workflow, the team mapped the full network behind one address, attributed it to real marketplaces and exchange deposit wallets, and turned a lead into legal-process targets in seconds rather than weeks.
The Nominis Platform has been used on numerous occasions to uncover large-scale weapons trafficking networks, often featured on the dark web. On this occasion, law enforcement agents were able to uncover a much wider operation from just a single starting point.
Closing the Crypto Intelligence Gap in Trafficking Investigations
As firearms trafficking increasingly moves through crypto, from dark web marketplace payments to laundering proceeds through exchanges, investigators face a growing challenge: understanding the network behind a wallet that traditional tracing tools or a single screening result cannot show.
Standard blockchain analytics can flag a wallet as high-risk or tie it to a known marketplace. But an investigator working a case needs more than a flag. They need to know:
Who else is connected to this wallet, and what other marketplaces or operators share its infrastructure Where the money is coming from, and how much has moved from each source Where the money is going, and which exchanges or cash-out points it touches Whether the wallet is still active, so a case can be built around current, not historical, activity Whether a lead is strong enough to put in an affidavit before legal process is requested.
Law enforcement therefore needs a deeper crypto intelligence layer, one that expands a single address into a mapped network, attributes that network to real entities with a confidence rating, and identifies exactly where legal process should be directed.
Adding a Deeper Crypto Intelligence Layer
Nominis provides investigators with a crypto risk intelligence layer that turns a single seized or recovered wallet address into a full picture of the network behind it.
The platform maps outward from that address, surfacing connected marketplaces, co-located operators, and related trafficking addresses, then traces the flow of funds to the exchange deposit wallets and cash-out services where those funds re-enter the regulated financial system.
By connecting fragmented on-chain signals across wallets, marketplaces, and exchanges, Nominis surfaces the wider structure behind a single lead. This lets investigators move beyond one address, understand the network around it, and act on evidence strong enough to support a production order, subpoena, or MLAT request.
The Challenge: Trafficking Networks Are Built to Look Isolated
Weapons trafficking wallets rarely announce their connections. A single marketplace wallet can look like an isolated node, when in practice it may be one point in a wider network of marketplaces, operators, and cash-out infrastructure sharing the same rails.
For an investigative team working a firearms trafficking lead, the key challenges included:
Limited visibility into the wider network behind a single seized or reported wallet Difficulty attributing anonymous addresses to real marketplaces or services No fast way to quantify fund flows between connected wallets Significant manual research to build a picture strong enough for legal process The need for current, not historical, intelligence to keep pace with a still-active target
Case Study | One Wallet Into a Wider Network
An investigative team was working a lead tied to a dark web weapons marketplace. The wallet, 19rQ*****YDcu, was still actively soliciting illegal weapons sales up to the day of the investigation.
Using the Nominis forensic tool, the team started from that single wallet as the central node. The tool mapped outward and surfaced a wider network of weapons marketplaces, including one, Weapons Marketplace B, that had been funneling funds directly into the central wallet.
Using the AI assistant Ask Casey, the team asked a plain-language question and received the total funneled from Weapons Marketplace B, almost $20,000, in seconds.
From that one starting point, the tool attributed a large number of additional weapons-trafficking-related addresses to the network, and surfaced connections to deposit wallets at one of the largest global cryptocurrency exchanges.
This gave the team a picture that went well beyond the original lead: the marketplaces feeding the central wallet, the addresses tied to trafficking activity around it, and the exchange deposit wallets where those funds cashed out. Because the central wallet was still live, the picture was current, giving the team a target whose behavior they could continue to monitor rather than a static, historical trail.
Business Impact
Key Outcome: Nominis turned a single wallet address into a mapped trafficking network and a set of concrete legal-process targets, in seconds rather than through days of manual link analysis.
Wider Network Visibility
The team gained a clear view of connected marketplaces, co-located operators, and trafficking-related addresses feeding a single wallet, well beyond what a standalone screening result would show.
Faster Attribution
Ask Casey delivered a quantified fund flow, almost $20,000 from a single connected marketplace, in seconds, without a dedicated blockchain analyst manually tracing each hop.
Clear Legal-Process Targets
Each exchange deposit wallet surfaced by the network map is a potential identification point, holding the KYC and account records an investigator can pursue through a production order, subpoena, or MLAT request.
Current, Not Historical, Intelligence
Because the central wallet remained live, the agency could monitor it and get alerted to new activity, keeping the investigation in step with the target's behavior.
Reduced Manual Research
What would otherwise take an analyst days of manual link analysis was surfaced directly from a single starting address, freeing investigators to act on leads rather than build them from scratch.
Summary
As firearms trafficking money increasingly moves through crypto, investigators need more than a single wallet flag. They need to understand who else is connected to that wallet, where the funds came from, where they went, and whether the target is still active.
By adding Nominis to an investigation, agencies can expand a single recovered or seized address into a mapped network, attribute that network to real marketplaces and services with a confidence rating, and identify the exact chokepoints, exchanges and cash-out services, where legal process can recover an identity.
