Verify, value, and document
a client's crypto.

Client due diligence & risk screening

Before or during an engagement, screen a client's wallets and their counterparties against OFAC, EU, UK, and UN sanctions lists and surface high-risk exposure — documented for your firm's risk file.

Proof of funds & source of wealth

Document a client's on-chain holdings and where the funds came from for lending, immigration, audits, or onboarding — with evidence links anyone can verify.

Audit & assurance support

Independently verify a client's stated crypto holdings and activity against the public ledger, rather than relying on a self-reported spreadsheet.

Valuation at a point in time

Capture balances and USD value as of any date you choose — the balance-sheet date, date of death, date of gift — useful supporting documentation for financial statements, estate, gift, and charitable-contribution work.

Forensic & dispute support

Trace funds across wallets and chains in shareholder, partnership, or fraud disputes, and turn opaque on-chain movement into a documented timeline.

Reconciliation support

Pull a complete transaction history to reconcile against a client's records and spot gaps — a verification layer alongside your tax software.

Organized by client engagement

File every analysis, trace canvas, and monitored wallet under a matter — a client or engagement with its own number and type (audit response, source-of-funds…). Run a conflict check before taking on a client, add your own commentary to any analysis, put your firm name and CPA license on the PDF, and export the whole engagement as one branded workpaper file — or share a draft via an email-gated “under review” link.

A workpaper-ready case file

Holdings, transaction history, entity attribution, risk screening, and a plain-English narrative — timestamped and exportable as a clean PDF, or as a tabbed Excel workpaper (summary & valuations, counterparty exposure with live tie-out totals, transactions, screening, methodology) that drops straight into your audit file. Every report is reproducible from public on-chain data and carries a tamper-evident content hash; how it was generated and verified is documented at walletdna.com/methodology.

Valuation as of any date

Pick the date that matters — the balance-sheet date, date of death, date of gift — and get the wallet's balance and USD value on that day, computed from archive block data (EVM chains) or full history replay (Bitcoin, Litecoin) and priced from a stated source. Each valuation saves with the report and renders as its own page in the PDF, with the principal-market judgment left to you.

Counterparty attribution

Where funds moved to or from a known exchange or service, with confidence tiers and a cited methodology — context a raw block explorer won't give you. Exchange exposure is graded in three evidence tiers: dated direct deposits, probable deposit addresses inferred from sweep patterns (funding and sweep transactions cited, stated as probable), and exchange endpoints reached across the trace.

Cross-chain bridge exits

When funds move to another chain through a bridge, the workpaper flags the exit rather than losing the trail — naming the destination chain for canonical bridges and stating honestly when a multi-destination router's destination isn't resolvable on-chain. It records where value left the chain; it does not infer where it landed, keeping the workpaper within what the on-chain data supports.

Proof the client controls the wallet

The ownership half of the existence assertion: send the client a signing link, they sign a challenge message with the wallet's key (browser wallet or offline/hardware), and WalletDNA verifies it cryptographically — proof, method, and timestamp embedded in the report. Works on Ethereum and all EVM chains, Bitcoin, Litecoin, Solana, and Tron.

Sanctions & risk screening

Automatic screening against OFAC, EU, UK, and UN lists, plus behavioral risk flags — the AML context relevant to client acceptance.

Ask the case file questions

An Investigation Assistant answers plain-English questions about the analyzed wallet — “which counterparties are exchanges, and how much flowed to each?”, “what was it worth on December 31?” — by driving the same tools that build the report. Every figure and address in an answer carries a numbered citation to the tool evidence behind it; answers that fail citation validation are never shown, so nothing lands in your file that the data doesn't support.

Deliverables you author

Answers become report content only when you add them as findings — under your heading, rewritten in your own words, re-validated against the evidence before saving. The PDF's Supplementary Findings page carries your name and firm, cites the underlying data sources per finding, and a one-line disclosure on the Methodology Declaration notes that findings derive from analyst-directed queries — the same way a workpaper cites its data services. Exploratory questions never reach the client file.
