Our Team

Paucitas is an independent expert firm for cryptocurrency and blockchain, founded in 2021 by Simcha Schrijver and Tyler Dijst, and the team records transactions, wallets and the origin of crypto assets in reports that clients can use themselves. The blockchain investigators at Paucitas form an experienced team, working worldwide from the Netherlands. Every investigator in our team brings their own background in data-driven investigation, blockchain analysis or support.

Together we form an independent firm specialising in investigations into digital assets. Our approach combines technical depth with practical accessibility. We explain technical findings in plain language, so that clients, lawyers and directors understand what matters and which conclusions follow from it.

Independence and transparency are central. We work confidentially and deliver reports that hold up in civil and criminal proceedings. In every case we look at both the technology and the context: which data is available, how does it relate to the account of the facts, and which next steps are realistic.

Our clients find us through referrals from lawyers, enforcement officers and previous clients. We are also engaged by private individuals who are looking for direct contact with an independent firm with no commercial interest in specific products or services.

Working worldwide comes naturally to us. Although our office is in Amsterdam, we regularly work on international cases. Time zones, languages and jurisdictions are points of attention for us, not limitations.

Our team at Paucitas forms an independent expert firm in which experienced investigators work together as blockchain investigators and crypto specialists. We guide you through investigations into blockchain, bitcoin and investment fraud. Whether you have been the victim of a scam, want to trace a missing wallet or need a thorough investigation report, a Paucitas blockchain investigator is ready to help.

Our approach is always focused on transparency and care. Every blockchain investigator in our team has extensive knowledge of transaction analysis, wallet investigation and tracing money flows on the blockchain. We also work closely with an independent blockchain specialist, so that technical questions and legal context are always considered together.

Paucitas stands out because we are not a loose collection of experts, but an expert firm in which different disciplines strengthen each other. A blockchain investigator on their own rarely solves everything, which is why teamwork is central to how we work. In every case we follow the same structured approach: intake, analysis, investigation, reporting and aftercare.

Blockchain expert is a specialist who analyses transactions on public and private blockchains to establish the ownership, origin and destination of digital assets. Our blockchain experts combine technical knowledge with insight into evidential value, so that conclusions can be used in both civil and criminal proceedings.

Crypto expert and crypto specialist are broad profiles within blockchain expertise, from technical wallet analysis and transaction tracing to support in cases involving crypto fraud, investment fraud, boiler room fraud or pig butchering fraud. At Paucitas, every crypto expert works from a factual methodology without commercial interests.

Blockchain specialist and bitcoin expert are terms for experts who focus on specific areas within blockchain and cryptocurrency, such as transaction tracing, clustering, wallet analysis and investigating the origin of assets.

Counter-expertise is an independent review by an external party of a blockchain investigation carried out earlier. Paucitas carries out counter-expertise for lawyers and parties to proceedings who want the methodology, source data and conclusions to be tested independently.

Origin of assets concerns showing where digital assets come from. Our reports are used by banks, solicitors and conveyancers, accountants, insolvency practitioners and in dealings with HMRC, for compliance, asset freezing and tax matters.

Transaction tracing is systematically 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.

At Paucitas, we believe that independence and transparency are the foundation of every good investigation. We work as a team in which technical analysis, legal context and clear communication come together. Every case is approached from a factual methodology, with respect for the procedural requirements that lawyers, insolvency practitioners, accountants, solicitors and public bodies place on their reports. We only ask for what the case requires and treat all information we receive confidentially.

Our experience covers a wide range of blockchains, exchanges and specialist service providers. We work both for private individuals with personal questions and for professional parties with legal cases. In practice, this means we adapt flexibly to the nature of the question, from a simple analysis to an extensive project involving multiple wallets, cross-chain movements and international counterparties. We always tailor our reports to the purpose they will serve.

What sets us apart is the combination of depth of content with practical accessibility. We explain technical findings in plain language, so that clients, lawyers, insolvency practitioners and judges can follow the conclusions and use them in their case. We also work according to a structured methodology that allows independent review, because the evidential value of our reports ultimately rests on that. The aim is always that the outcome stands up to critical scrutiny.
