Scam investigation
From $350 USD · scope agreed individuallyLost funds, suspicious transfers or a project that has stopped answering? I investigate the available evidence to establish what happened and trace where the money went.
There is no fixed upper limit. The fee depends on the agreed scope, complexity and research time. It can cover transfers, relationships between wallets, project claims and supporting records. You receive documented findings, source links and any questions the evidence cannot resolve.
Email the project name, wallet addresses or transaction IDs, relevant documents and what you want to find out. I will confirm the proposed work, fee and timing before you pay. Work begins once we have agreed and payment has arrived.
Publication on X by agreement
At the client’s request and by prior agreement, documented findings can be published on X. We agree on what is published and when before anything is posted.
Payment covers the research
An investigation may end without conclusive findings or an identified responsible party. The agreed fee pays for the research carried out and remains due even if nothing is found. Recovery of funds is not guaranteed.
