Which blockchains can you trace funds across?
We trace across the major public blockchains that Chainalysis Reactor and TRM Labs support — including Bitcoin, Ethereum and the major EVM-compatible chains, Tron, Solana, and many others. Coverage extends across more than seventy chains in practice. Privacy-focused chains and protocols are handled with the analytical techniques appropriate to each — we are direct with clients about what is and is not tractable on chain.

Are you Chainalysis-certified?
Yes. DataExpert is a Chainalysis partner and our cryptocurrency investigators hold current Chainalysis Reactor certifications. We also hold certifications with TRM Labs. Maintaining both is part of our vendor-agnostic posture — we choose the tool that fits the case rather than the tool that fits the contract.

How quickly can you start a tracing investigation?
For known clients with active retainers, we can begin tracing within hours of receiving the relevant wallet addresses and case context. For new clients, the gating items are scoping, conflict-checking, and contracting — typically completed within one to three business days. Where speed is critical — for example, an active ransomware payment — we will prioritise scoping accordingly.
Can your reports be used in court?
Yes. Our cryptocurrency tracing reports are written to be admissible as evidence in European courts and are routinely cited in regulatory and law-enforcement proceedings. Our investigators can give expert-witness testimony where required. We follow documentation standards consistent with our wider forensics practice.
Do you support ransomware investigations?
Yes. Ransomware proceeds-of-crime tracing is one of our most active workstreams. We work with victims, their insurers, and law-enforcement partners to trace ransom payments, identify counterparties, and support recovery action where it is realistic. We are direct with clients about what is and is not likely to be recoverable in any given case. We do not facilitate ransom payment itself.
Can you work with regulated financial institutions on AML cases?
Yes. We support EU banks and crypto-asset service providers with AML investigations, sanctions-exposure analyses, and supervisory-engagement work. Engagements typically integrate with the bank's existing AML platform and produce intelligence packages suitable for suspicious-activity reporting to national financial-intelligence units.
How do you handle mixers, privacy protocols, and cross-chain bridges?
Mixers and privacy protocols are handled with the analytical techniques appropriate to each — heuristic clustering, behavioural correlation, off-chain signal pairing — and we are honest with clients about confidence levels. Cross-chain bridges are now well-instrumented in both Reactor and TRM Labs and we trace across them as part of routine practice. The current state of the art on each topic shifts month to month; we keep our team current.
Do you work with law enforcement directly?
Yes. A significant proportion of our cryptocurrency-tracing work is delivered on instruction from European law-enforcement and regulatory bodies. We are practised in the protocols and disclosure regimes these engagements require, and we maintain working relationships with the relevant national agencies and EU-level coordination bodies.
