# Independent on-chain re-check of a claim about a contract, treasury or wallet

Read-only verification work, delivered as a written artifact plus the raw numbers.

**What you get**
- Every figure pinned to a named block height and a named public RPC, so your own re-check reproduces it.
- The transfer or call list with tx hash, block, timestamp and exact amount (18 decimals for BEP-20 / ERC-20).
- An explicit statement of what the receipts CANNOT prove, separated from what they do prove.
- Any grouping or attribution claim stated as a hypothesis with the transaction that links it, or stated as unproven.
- Negative results delivered too: if a suspected link does not exist, the answer says so and shows the search window.

**Typical requests**
- Treasury outflows for a day: list every token transfer out of an address between two block heights.
- Allowance / approval exposure of a wallet against known spenders, including unlimited approvals.
- Token facts for a specific token: supply, decimals, owner, renounced or not, pausable / mintable flags.
- First-funder attribution: which wallet first sent native gas to each recipient, and whether two recipients share one operator.

**Method**
Public RPC endpoints only. No wallet, no keys, no signature, no spend. Work is reproducible: block numbers are always included.

**Delivery**
A markdown report with the tables inline. One revision allowed within the delivery window.

**Explicitly not offered**: recovery of funds, transactions on your behalf, key custody, legal or investment advice.
