Why contact Paucitas straight away about crypto fraud or investment fraud?
Every hour counts
If you suspect crypto fraud or investment fraud, every hour counts. Early contact with a Paucitas specialist can make the difference between guesswork and focused next steps. Our blockchain investigators and fraud specialists reconstruct wallets, transaction flows and counterparties in a report that anyone can check step by step, including for tax and legal next steps. Read more about our services for blockchain investigation and asset investigation.

When is it wise to contact Paucitas?
Five situations
We are often approached by private individuals, business owners and law firms with very different questions. A first conversation with Paucitas is a good idea in case of:
- Suspected crypto fraud, romance scams or boiler rooms
- Unexplained transactions or missing wallets
- An overview of your assets for your Self Assessment tax return or questions from HMRC
- Reconstruction of payment flows after investment fraud
- An independent assessment of a case before legal steps are taken

What can you do with the Paucitas report?
A complete and traceable picture
The Paucitas report shows whether money is still available, or where it went, and which next steps are possible. If you decide to report it to the police (through Report Fraud in England, Wales and Northern Ireland, or Police Scotland on 101), the report is a strong attachment that sets everything out fully and clearly. To prepare it, Paucitas reads out all conversations, documents, emails and other communication and puts everything into a timeline. To check whether a provider is already known to the regulator, consult the FCA Warning List.

Key terms
Intake, confidentiality, orientation
Intake is the first confidential conversation in which we map out the facts, the wallets involved and the investigation question.
Confidentiality means that all information you share is used exclusively for your case and is not shared with third parties without your consent.
Orientation is a free initial assessment in which we indicate whether and how we can help you, without any engagement being created.
Urgent case is a case in which speed is critical, for example with ongoing transactions or an approaching limitation period; in such cases we can act immediately.
