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.
A prominent UK law firm approached us on behalf of a client who was experiencing issues with his bank while cashing out crypto assets.
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.
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.
We produced multiple source of funds documents, which were accepted by the client's bank and later also by the tax authorities.
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.
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.
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.
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.
Crypto Source-of-Funds verification is the process of reconstructing and documenting where crypto assets came from, how they moved, and whether the available evidence supports a clear explanation of their origin. It usually combines blockchain analysis, wallet mapping, exchange records, bank statements and supporting documents into a structured report for review by exchanges, banks, tax authorities, legal teams or compliance departments.
You may need a Source-of-Funds report when an exchange restricts your account, a bank asks for proof of origin, a tax authority reviews crypto-related income, or a legal team needs independent evidence of crypto wealth. It can also be used in third-party due diligence before a transaction, investment, settlement, inheritance matter or business relationship.
Yes. If an exchange account is restricted, a Source-of-Funds report can help organise the evidence needed to explain the origin and movement of funds. The report can map relevant wallets, exchange accounts, transactions and supporting documents into a structured explanation that the exchange compliance team can review. Acceptance always depends on the exchange and the quality of the underlying evidence.
Typical documents include wallet addresses, transaction hashes, exchange exports, trading history, bank statements, purchase records, sale records, tax filings, contracts, invoices, screenshots of relevant account activity and any request received from the bank, exchange or authority. The exact documentation depends on the case, the time period under review and the reviewing party’s requirements.
A crypto Source-of-Funds report can include wallet and exchange account mapping, a chronological transaction timeline, source and destination analysis, cross-chain flow reconstruction, comparison with bank and exchange records, structured annexes, risk indicators, inconsistencies and follow-up support for reviewing parties.
Yes. Source-of-Funds reviews often involve activity across multiple wallets, exchanges, chains and services. The purpose of the review is to reconstruct the relevant transaction history and connect on-chain activity with off-chain records such as bank transfers, exchange exports and supporting documents.
Yes. Source-of-Funds verification can support third-party due diligence before a transaction, investment, settlement, business relationship or legal process. It helps assess whether the available wallet, exchange and transaction evidence supports the claimed origin and movement of crypto assets.
Yes. Source-of-Funds analysis can support third-party wealth checks where crypto assets need to be assessed before a transaction, investment, settlement, business relationship or legal process. The analysis can help identify whether the available evidence supports the claimed origin and movement of funds.
No. No independent provider can guarantee acceptance by a bank, exchange, tax authority or compliance department. Acceptance depends on the reviewing party’s internal standards, the completeness of the evidence and the underlying transaction history. The purpose of the report is to provide a clear, structured and evidence-based explanation.
You can start by submitting the basic details of the case, including the reason for the review, the reviewing party involved, the relevant wallets or exchanges and a short description of the issue. The next step is an initial assessment of the documentation needed, clarification of scope and, where suitable, a proposal for report preparation.
