Blockchain investigator, Milan
Guglielmo Anfossi
Blockchain investigations and investigative systems.
I trace digital assets across mixers, bridges, DeFi and services, reconstructing the activity behind financial crime.
$10.5M USDT
Investigative work behind a single-case freeze and recovery of $10.5M in stolen USDT, with Swiss authorities.
Work carried out as part of a small team.
11.7K BTC
Bitcoin traced through a mixer. Overflow analysis narrowed the window; volume isolated the cluster.

Notes on blockchain investigations, financial crime and the structures that make digital assets difficult to trace.
How I can help
For law firms
A finding should stand without you.
I turn complex on-chain activity into something lawyers, clients and courts can understand. I reconstruct what happened, explain the relationships and mechanisms involved, and make the path from transaction to conclusion clear.
The goal is not to overwhelm with technical detail, but to make the important parts impossible to misunderstand.
For exchanges and investigation teams
Not every investigation is a question of where the money went. Sometimes the trail is the wrong place to look.
I investigate the structures behind on-chain activity: the shared infrastructure, repeated behaviours, contract relationships, timing and economic constraints that reveal who is operating a system and how it works.
When the obvious trail ends, I change the question. I use what the chain exposes beyond the movement of funds to identify patterns, test hypotheses and reconstruct activity that ordinary tracing would miss.
For data science teams
Laundering hides in relationships, not transactions. An ontology gives those relationships a shared language, so every pattern, from peel chains to cross-chain hops, means the same thing to every analyst, tool and model.
I build ontologies from real investigations, so patterns are labeled consistently, models can reason over them, and every finding can be explained.
About
I investigate systems by understanding their constraints. Today, that means blockchain.
