Primary sources

To prove crypto source of funds to a UK solicitor, build a continuous evidence trail: show how you obtained the original money, the bank transfer or income record, the exchange purchase, the movement into and between wallets, the eventual sale, and the fiat arriving in your bank. Label transfers between your own accounts so they are not mistaken for unexplained deposits.

A wallet screenshot only shows a balance at one moment. A structured wallet statement can organise the on-chain part into dated transactions, running balances and blockchain references, but it does not replace bank statements, exchange records or evidence of the original source. Ask your solicitor what period and documents they require before submitting the pack.

What your solicitor needs to establish

UK firms generally distinguish between two related questions. Source of wealth is how you accumulated your money overall (for example, years of salary or a business sale). Source of funds is where the specific money for this transaction came from and how it reached your account. When crypto is involved, reviewers usually want to follow the chain from the original income, into fiat or crypto purchases, through your wallets, and out to the destination — for example a property deposit.

Why crypto raises extra questions

Because crypto can move between wallets and exchanges quickly and pseudonymously, reviewers often ask for more detail than they would for a standard bank account. A single balance figure rarely answers their questions. They typically want to see dated transactions, the wallets involved, and how the on-chain activity connects to your verified identity and bank records.

Documents commonly requested

Requirements vary by firm, but a source-of-funds pack for crypto often includes:

  • Bank statements showing the original income (salary, business income, savings)
  • Records of fiat-to-crypto purchases (exchange order confirmations or statements)
  • Wallet transaction history with dates, amounts and balances
  • Exchange account statements and withdrawal records
  • Identity verification (KYC) details held by your exchange
  • An explanation note tying the trail together in plain English

A practical checklist to prepare your evidence

  • List every wallet and exchange account that holds or held the relevant funds
  • Gather bank statements covering the original source of the money
  • Export transaction history for each wallet (BTC, ETH, USDC, USDT)
  • Match exchange purchases to the matching bank transfers
  • Note any transfers between your own wallets so they aren't mistaken for new income
  • Write a short summary explaining the journey of the funds
  • Keep everything dated and in chronological order

How a wallet statement fits in

A structured wallet statement can turn raw blockchain data into a readable, dated export. Instead of asking a reviewer to interpret block explorers, you can provide a PDF and CSV that list transactions, amounts, running balances and blockchain references for the selected address. CryptoBankStatement provides a free preview and charges £3.99 to unlock both downloads. The files support — but do not replace — the rest of your evidence.

Common pitfalls to avoid

  • Submitting only a screenshot of a current balance
  • Leaving gaps where funds appear without an explanation
  • Forgetting internal transfers between your own wallets (these can look like new deposits)
  • Mixing multiple wallets without labelling which is which
  • Assuming one firm's requirements match another's

How CryptoBankStatement can help

CryptoBankStatement turns supported BTC, ETH, ERC-20 USDC and ERC-20 USDT activity into a dated PDF and CSV with balances and blockchain references. Preview the result for free, then unlock both files for £3.99. Add the statement to your bank records, exchange exports and written explanation; it supports the on-chain part of the evidence trail rather than certifying the lawful origin of the funds.

Important limitations

CryptoBankStatement is not a bank, accountant, solicitor, tax adviser, immigration adviser or financial adviser. This content is not legal, tax, financial, immigration or banking advice. The receiving institution decides what documents it accepts. A wallet statement does not guarantee acceptance, does not replace bank statements or exchange records, and requirements vary between firms. Always confirm exactly what your solicitor, conveyancer or lender requires.

Frequently asked questions

How do I prove crypto source of funds to a UK solicitor?
Provide a chronological trail from the original source of the money through your bank, exchange and wallets, then back into fiat if the crypto was sold. Include bank statements, exchange purchase and sale records, wallet transaction history, and a short written explanation. Your solicitor may request more evidence depending on the transaction and risk assessment.
What is the difference between source of funds and source of wealth?
Source of wealth is how you built up your money overall; source of funds is where the specific money for this transaction came from and how it reached your account. UK firms often ask about both when crypto is involved.
Is a wallet screenshot enough to prove source of funds?
Usually not. A screenshot shows a balance at one moment but not the dated trail of where funds came from. Most reviewers expect transaction history and supporting records.
Do I need to show my bank statements too?
Often yes. Reviewers typically want to connect your crypto activity back to verified income, so bank statements showing the original money are commonly requested alongside wallet records.
Can a crypto statement be used for a UK mortgage deposit?
It can be provided as part of your evidence to support a review, but acceptance depends on the lender. Requirements vary, so confirm what your specific lender or solicitor needs.
What if I moved funds between my own wallets?
Note these internal transfers clearly so they are not mistaken for new income. Labelling each wallet and explaining the movement helps reviewers follow the trail.
