Source-of-Funds Documentation
Document your crypto's
on-chain history.
A dated, methodology-backed record showing your wallets have no sanctions exposure, no mixer or known scam-network contact, and a verifiable transaction history — supporting documentation when a bank, court, lender, or immigration officer asks for source of funds.
Supporting documentation — not standalone proof.
WalletDNA documents the on-chain side: what your wallet did and didn't touch, and what the public ledger shows about its history. Banks, courts, and immigration officers usually also want off-chain documentation — pay stubs, exchange withdrawal records showing salary or business income converted to crypto, tax returns. WalletDNA produces the on-chain half of that package, in a clean, dated, exportable form. We're honest about that because the report is more credible when it's clear what it is and isn't.
Where this comes up
Bank account frozen after a crypto cashout
You moved funds from an exchange to your bank and the bank flagged it for AML review. They want documentation of where the crypto came from and that the wallets involved are clean. WalletDNA produces the on-chain half of that file.
Mortgage or lending — source of funds for a deposit
Lenders increasingly accept crypto-derived deposits, but require documented source of funds. WalletDNA produces a dated record of the wallet's history and counterparties — to sit alongside your exchange withdrawal records and tax filings.
Immigration, visa, or residency applications
Many investor-visa and residency programs require documentation of asset legitimacy. A WalletDNA report shows the on-chain history with sanctions and risk screening — useful supporting evidence when crypto is part of your declared wealth.
Divorce — defending against laundering or hiding allegations
If you've been accused of moving funds through mixers or hiding crypto, a dated WalletDNA report on your own wallets is documented evidence of what they actually did — and didn't — touch. Useful for your counsel to put in front of the court.
Private banking and wealth-management onboarding
Private banks running enhanced due diligence on a crypto-rich client want source-of-funds documentation that goes beyond a screenshot. WalletDNA produces a structured, methodology-cited file the compliance team can review.
Audit or tax-authority source-of-funds request
When a tax authority asks for documentation supporting your declared crypto income or holdings, a WalletDNA report provides the on-chain record — to be packaged with your tax filings, cost-basis reports, and exchange statements.

Holdings, transaction history, counterparty attribution, sanctions and risk screening, and a plain-English narrative — timestamped and exportable as a clean PDF for your file.
Sanctions and risk screening
Every address screened against OFAC, EU, UK, and UN sanctions lists, plus behavioral risk flags (mixer contact, known scam networks, high-risk services). A clean report is a documented clean record.

Where funds moved to or from a known exchange or service, with confidence tiers and a cited methodology — context that turns raw block-explorer data into something a reviewer can read.

Request a documented reportSource-of-funds documentation — FAQ
Will a bank or court accept this as proof of source of funds?
A WalletDNA report is supporting documentation — a dated, methodology-backed record of what your wallet did and didn't touch on the public ledger. It is not a standalone substitute for off-chain records like pay stubs, exchange withdrawal statements showing the salary or business income that became crypto, or tax filings. Most reviewers want both: the off-chain documentation showing where the money originated, plus the on-chain documentation showing it stayed clean. WalletDNA produces the on-chain half cleanly; you pair it with the off-chain half from your records.
What if I already have exchange statements and tax records?
Good — those cover where the funds came from. WalletDNA adds what happened on-chain after that: which wallets the funds moved through, whether any of them touched sanctioned addresses or known scam networks, and what the public ledger shows about the history. Together, the two pieces are the standard source-of-funds package.
Do I need a lawyer or accountant to use this?
Not to run the report. But if a bank, court, immigration authority, or tax authority has asked you for source of funds, having counsel package the WalletDNA report alongside your other documentation is usually the right move — particularly in litigation or formal compliance reviews. We have dedicated pages for lawyers and accountants who do this work.
What if my report surfaces a flag I didn't know about?
Better to know now than to be surprised by the bank's compliance team. Most flags have explanations — an address you sent a small payment to may have later become associated with a scam, or a counterparty exchange may have been on a high-risk list at the time. The report shows the evidence and lets your counsel address it directly rather than be ambushed.
Whose wallet does this work for — mine, or someone else's?
Either. This page is about documenting your own wallets defensively — proving they are clean. The same product also analyzes other parties' wallets for tracing or due diligence (see /for-lawyers and /for-accountants). Same report format; different posture.
What does the report contain?
Balances and dated USD valuation, transaction history, counterparty attribution (with confidence tiers and a cited methodology), sanctions and risk screening against OFAC/EU/UK/UN, behavioral risk flags, evidence links to public block explorers, and a plain-English narrative — exportable as a PDF.
Which blockchains and assets are supported?
Bitcoin, Ethereum, Solana, XRP, Tron, BNB Chain, Polygon, Litecoin, Cardano, Polkadot, Avalanche, Cosmos, Stellar, Base, Arbitrum, Optimism, TON, and SUI. Tron (USDT-TRC20) — the most common stablecoin rail — is fully supported.
