Services

From our office in the Netherlands, our firm carries out professional blockchain investigations worldwide, with on-chain transaction analysis for private individuals, businesses, law firms, insolvency practitioners, public bodies and many other organisations. Our investigators trace crypto transactions, analyse wallets and produce well-founded reports that can be used in court and financial proceedings. Whether it concerns suspected crypto fraud, investment fraud involving digital assets, a dispute about the origin of assets or mapping out lost cryptocurrency, we combine technical depth with practical experience. Victims of crypto fraud often do not know where to start, and that is exactly where we offer something to hold on to. For a direct conversation with a blockchain specialist, please visit our contact page.

A blockchain investigation at Paucitas always starts with a thorough intake. We map out which wallets, transactions and counterparties are relevant to your case. We then follow the flow of money across the chain, including where mixers, bridges and cross-chain swaps have been used. Tracing stolen crypto is done step by step, with attention to every split and destination. The results are recorded in a clear report with methodology, sources and concrete conclusions. Investment fraud involving crypto is still on the rise, as the City of London Police figures on investment fraud also show. An independent investigation helps victims, law firms, insolvency practitioners and deputies to get a grip on the facts.

Why choose Paucitas

Our blockchain investigators work confidentially, independently and with demonstrable expertise. We are registered with the Dutch Chamber of Commerce as a specialist investigation firm. Our team consists of specialists with a background in investigation and blockchain analysis. We follow developments in crypto fraud, investment fraud and new money laundering methods closely, so our analyses always stay up to date. Where possible, we also look into whether restoring access to your own wallet is technically possible, as long as (partial) access codes are still available. Sometimes that works, sometimes it does not.

Alongside blockchain investigation, we also offer help with investment fraud and crypto fraud (including address monitoring), expert reports, wallet recovery, verification of the origin of assets and personalised aftercare after crypto fraud. Tracing stolen crypto is often the basis for the next steps in a case. For relevant background information and case studies, please see our blogs. You can read more about the approach and philosophy of our firm on the About Paucitas page. Would you rather see and hear us talk about our work?

Who our blockchain investigation is for

We work for victims of investing scams, romance scams, investment fraud, crypto fraud and ransomware attacks, for law firms that need thoroughly substantiated evidence in proceedings, for insolvency practitioners who want to locate crypto assets in an insolvency, and for businesses with compliance questions about the origin of incoming crypto. Every case is unique, which is why we put together a tailored approach. Ask for an initial indication at paucitas@paucitas.com or through the contact form on our website.

The scale of crypto fraud and investment fraud in the UK is much larger than the reported figures show. The Office for National Statistics estimates, based on the Crime Survey for England and Wales (Nature of fraud and computer misuse in England and Wales: year ending March 2025), that there were around 4.2 million incidents of fraud in that year, a 31% increase on the year before. The ONS also notes that a large proportion of fraud victims do not report what happened. The gap between what people experience and what is reported shows how far this phenomenon operates under the radar.

In April 2025, the City of London Police, the national lead force for fraud, published its figures on investment fraud: over £649m lost to investment fraud in 2024. That year, 25,843 reports of investment fraud were made. Cryptocurrency was the most common asset that victims believed they were investing in, appearing in 66% of all reports. The police also point out that AI generated images and videos were used to promote bogus investment schemes, and that over £10m was lost to fraudsters using the identities of well-known people.

Why specialist investigation is needed

Crypto flows move through mixers, bridges between blockchains and foreign exchanges, and across several jurisdictions at once. Following those flows to an identifiable end point requires specialist blockchain expertise. We provide that investigation and give clients a substantiated answer to the question of where the money ended up.

How Paucitas establishes the facts

Paucitas specialises in exactly this field: blockchain investigation, crypto fraud analysis, investment fraud cases and tracing stolen crypto. Our blockchain expertise allows us to map out crypto assets in full, to break down transaction patterns between wallets and exchanges, and to deliver reports that anyone can check step by step, for law firms, insolvency practitioners and public bodies. We establish the facts where other parties have stopped or could not carry out a technical investigation. Our services include blockchain investigation, crypto fraud investigation, counter-expertise on blockchain cases, tracing stolen crypto and support in investment fraud cases.

Clients often come to us when they have many questions about a crypto case, have doubts about an earlier analysis or need an independent, in-depth assessment. The sooner we are involved, the greater the chance that traces on the blockchain can still be followed and the stronger the final case file will be. If you have a question, a suspicion or a case, you can get in touch directly through the contact page for a confidential first conversation.

Blockchain investigation is the systematic analysis of transactions on public and private blockchains to establish the origin, destination and ownership of digital assets. It combines technical data analysis with a legal context.

Wallet recovery covers locating, analysing and, where possible, restoring wallets, provided partial access details are available.

Counter-expertise is an independent review of an investigation or report carried out earlier. Our firm carries out counter-expertise for law firms and parties to proceedings who doubt whether an analysis is correct.

Transaction tracing is following crypto transactions through wallets, exchanges and mixing services in order to identify ultimate beneficiaries or source addresses. It is a core part of blockchain investigation.

Origin of assets concerns showing where digital assets come from, often required by banks, exchanges, solicitors and conveyancers or in tax matters under anti-money laundering rules.

CARF (the OECD Cryptoasset Reporting Framework) requires UK crypto service providers to collect user and transaction information and report it to HMRC, from 2026. Paucitas explains what this means for compliance in practice.

Investment fraud and crypto fraud investigation is mapping out fraudulent investment schemes and crypto scams, in line with the work of Europol on economic crime.

Chain-hopping is an evasion technique in which fraudsters move crypto between different blockchains to hide their tracks. Our investigators recognise and unravel these patterns.
