Connect the capital’s origin, asset acquisition, transfers and conversion. For a property purchase in France, the evidence should explain the full chain through to receipt of euros, rather than only the current balance. Wallet control does not establish the origin of funds. Agree the documents and unresolved questions with the bank and notary for your transaction history.
What is a source-of-funds pack for?
The bank and notary need to understand how the capital was obtained, not only where it is held today. For a property in France, multiple wallets, transfers between platforms or gaps in records may require explanations. No universal checklist guarantees acceptance: agree the evidence with the participants reviewing your file.
If you have found a property, start with the listing and a conversation. Property checks and funding preparation can proceed in parallel; establish financial feasibility and conditions before making commitments. See the crypto-funded purchase overview for the sequence.
Which records should connect?
Connect records from the original income to receipt of euros. For a purchase in France, this table helps explain the chain to the bank and notary, who will specify the evidence required.
| Evidence | What it explains | What to check |
|---|---|---|
| Original income and acquisition records | Where the capital came from: earnings, asset sale, inheritance or another source | Supporting documents and their connection to the amount invested |
| Platform statements: deposits, trades and withdrawals | Asset acquisition and movements | Account holder, dates, amounts and complete history |
| Wallet-control evidence | The connection between an address and its holder | A verification method acceptable to the reviewer |
| Transfer summary | Movements between accounts and wallets | Counterparties and explanations for major transfers |
| euros conversion confirmation | How settlement funds were obtained | Provider, amount, fees and date |
| Bank statement and short explanation | Euro receipt and the complete chain | Consistent names, amounts and payment details |
Is proof of wallet control enough?
No: controlling an address does not prove the lawful origin of everything it holds. For a property in France, map “original source → acquisition → wallet/account → conversion → bank”. Agree the control-verification method with the reviewer. If a signed message is requested, first understand its content and purpose. Do not provide private keys or seed phrases.
A blockchain tracing report may be requested for a particular file, but it is not a universal requirement or a substitute for underlying evidence. Ask the bank or notary whether one is needed and in which format before commissioning it.
What should I retain after conversion?
The transaction confirmation, fees, receiving euros bank statement and agreed payment details. For a property in France, an authorised provider does not imply bank acceptance: the guide to participants’ roles and checks explains whom to ask.
French tax residents holding foreign digital-asset accounts should check the reporting obligation under form 3916-bis; form 3916 concerns bank accounts. This is a separate tax question, not a prerequisite for the first property discussion. See DGFiP on digital assets and declarations.
What is missing from your own history?
Send the property link and a brief funding outline: the assets, where they are held, whether conversion has occurred and whether you have spoken to the receiving bank. For a property in France, our conversation will identify existing evidence and questions to agree with the bank and notary. You do not need to send a complete document archive to start.

This guide does not set a price or turnaround time for individual work. Before commissioning it, agree scope, cost and timing with the notary and relevant professional; for a purchase, do so before the relevant commitment.
