A specialist digitalassets investigations & intelligence firm
From the blockchain to evidence, intervention and enforcement.
Collisionless investigates complex digital-assets theft, fraud and financial crime. We turn on-chain intelligence into real-world outcomes for counsel, institutions, governments and asset owners.
THe firm
Collisionless operates where on-chain intelligence meets real-world consequence — in investigations, in regulatory oversight, and in understanding threats before an incident occurs.
Blockchain tracing is one component of a much broader investigative process: on-chain and off-chain investigation, attribution, counterparty engagement, evidence development, and coordination with counsel, exchanges and law enforcement.

How an investigation unfolds
01
Trace
On-chain analysis across assets, chains, bridges and mixers.
02
Attribute
Off-chain investigation connecting activity to actors and infrastructure.
03
Intervene
Identifying intervention opportunities and engaging the exchanges and intermediaries able to freeze and preserv
04
Evidence
KYC and records development, investigative reporting, Kovel engagements.
05
Enforce
Support for counsel-led recovery, enforcement and litigation strategies.
Recovery is sometimes possible, often difficult, and never guaranteed. Where it is realistic, our evidence supports the counsel-led and law-enforcement-led efforts that make it happen. We are equally direct when recovery is not realistic.
Practitioner-led
Live matters. Institutional perspective.
Collisionless works across complex live investigations and the institutional systems that surround them. We see how digital-assets risk develops in practice, how sophisticated actors move assets, and where investigative findings can create real-world leverage.
Our work with governments, regulators and institutions brings the other side of that perspective: how evidence is assessed, how financial-crime risks are understood, and what is required to turn intelligence into action.

Before you engage us
Common questions
How are you different from crypto-recovery firms?
Collisionless is a digital-assets investigations and intelligence firm, not a recovery service. We develop evidence, engage intermediaries, and coordinate with counsel and law enforcement — the work that makes recovery and enforcement possible when they are possible. We do not advertise guaranteed outcomes, and we tell clients plainly when recovery is unrealistic.
How fast can you engage on an active incident?
Contact us as soon as possible. In an active incident, speed can materially affect the available intervention options — particularly while assets are on or near exchanges, issuers or other intermediaries. Our intake is designed to surface urgent matters quickly.
Can your findings be used in court or with law enforcement?
Evidence development is the point of our work. We produce investigative reporting built to hold up with counsel, courts and law enforcement, work under Kovel engagements with outside counsel, and routinely coordinate with investigative agencies.
