Terms and method

What Fundsheet is

Fundsheet produces a factual statement of public blockchain activity for addresses you list: transfers, values at the time, first-hop sources with public labels, holdings, sanctions-list screening, and your optional ownership signatures. It is not an audit, certification, valuation, or legal, tax or financial advice. It does not establish who owns an address unless the report shows a verified signature. The institution reading the report decides what it accepts.

Method

• Collection: your browser reads Blockscout v2 explorer APIs (EVM chains) and mempool.space (Bitcoin). Very large histories are limited to the most recent 2,500 transfers; the report says so.
• Cross-checks: our server re-reads a random sample of transactions and all balances directly from public JSON-RPC nodes and reports matches, mismatches and a balance reconciliation.
• Values: daily USD prices from DefiLlama; currency conversion with European Central Bank reference rates (via Frankfurter). Tokens without a market price are listed separately and left out of totals.
• Labels: exchange wallet labels from the open eth-labels dataset (MIT licence). Labels can be incomplete or out of date; an unlabeled address is not a finding.
• Screening: the US Treasury OFAC SDN list of digital currency addresses, via the open extract by 0xB10C (updated daily), compared with your addresses and every direct counterparty. Results read "No known issues" or "Check this".
• Signatures: EIP-191 personal_sign (and EIP-1271 for contract wallets) on EVM; BIP-137 signed messages on Bitcoin. BIP-322 signatures are recorded as "could not verify".
• Integrity: each report has an ID, a SHA-256 hash of its data and a SHA-256 hash of the PDF file, published on the verification page.

Price and payment

15 USDC per report (up to 10 addresses), paid onchain to the Mintward receiving address in native USDC on Base, Ethereum, Arbitrum, OP Mainnet or Polygon, or over x402 on Base.
