We map the full flow of funds and identify all relevant transactions.
Crypto source of fundsverification.
Many crypto users first encounter Source-of-Funds (SoF) verification when their exchange account is suddenly restricted: withdrawals are blocked, trading is disabled, and they are asked to “provide documentation confirming the origin of funds.”
But SoF verification is not only relevant after a freeze. Our service supports clients who need to document the origin of their own crypto assets for an exchange, bank, tax, or compliance review, as well as clients who need to assess the origin of crypto wealth held by a third party before a transaction, investment, business relationship, or legal process.
In both cases, we help establish a clear, evidence-based transaction history and prepare structured documentation demonstrating where the funds came from and how they moved.

Resolved cases
Some of the cases we helped resolve
Crypto source of funds cases require more than transaction exports. These examples show how we reconstruct complex trading histories, compare reported claims with on-chain evidence, and prepare documentation that can be reviewed by banks, law firms and tax authorities.
Source of funds case for high-volume crypto trading history
Case overview
A prominent UK law firm approached us on behalf of a client who was experiencing issues with his bank while cashing out crypto assets.
Situation
The client needed a full source of funds report covering more than seven years of intensive crypto trading across multiple blockchains. The matter required a clear reconstruction of the client's crypto activity and supporting documentation that could be reviewed by financial and tax authorities.
Our work
We conducted an in-depth investigation of the client's complete crypto trading history. In total, we analysed and mapped over 20,000 transactions, identified more than 200 services used by the client, and examined over €100,000,000 in total transaction volume.
Outcome
We produced multiple source of funds documents, which were accepted by the client's bank and later also by the tax authorities.
Tax authority verification case involving claimed crypto trading income
Case overview
In early 2026, a European tax agency contacted us to verify a substantial volume of transactions reported by an individual who claimed the funds came from crypto trading over several years.
Situation
The tax authority needed an independent review of the submitted report to determine whether the individual's claims were supported by actual on-chain evidence.
Our work
We conducted a thorough crypto tracing investigation and compared the claims in the submitted report against the corresponding blockchain activity. We reviewed the transaction flows, supporting wallet data, and relevant on-chain evidence.
Outcome
We prepared a forensic report with accompanying on-chain evidence, confirming certain claims and disputing others where the submitted information did not match the blockchain data.
