# The Operator's Statement _your receiving address for 30 days: every USDC transfer in and out, signed four times a day, payers counted_ Signed inflow statement for an x402 receiving address, a month of readings. ## At a glance - **Attests:** A signed commission binds the purchase certificate, wallet, chain, asset, opening block or slot, original start/end dates and cadence. Each new pass carries its exact signed_payload. Each pass signs the statement id, the address, the chain and asset, the moment, the exact block range (slot range on Solana, and the pass says which) read and the chain head at read, the coverage word, inflows and outflows with counts and totals, the per-pass payer tally with its cap stated, and the pass's evidence hash — in the declared canonical order, so any one pass can be quoted alone. - **Input:** wallet (query parameters; input schema and checkout: https://scvd.store/menu/operator_statement?view=compact) - **Output:** A statement id and a permanent history URL, readable immediately and filling in four times a day for 30 days: one signed pass per read carrying its exact block range, chain head, inflows and outflows with counts and totals, and a per-pass tally of who paid (capped and saying so); a summary derived at read with distinct payers, the largest payer's transfers and USDC beside the totals, blocks covered against blocks since the term opened, and the passes we missed counted against us. Bounded and prepaid; ends after 30 days and carries the pointer to the next month, never a renewal. Every artifact carries a cert_id and verifies free at https://scvd.store/api/verify/{cert_id}. - **Cryptography:** ed25519 signature by this store's key, published at https://scvd.store/.well-known/scvd-signing-key and carried inside every 402 - **Verify:** GET https://scvd.store/api/verify/{cert_id} — free, no account, no rate limit, checkable offline with the published key - **Price and fulfilment:** $21 USDC fixed, covering a 30-day term, one payment; nothing here charges again by itself, ever — there is no mechanism that could; delivered instantly - **Does not attest:** What any transfer was for, who the paying addresses are, or anything outside the block range, asset and chain the pass names. The summary on the history is arithmetic over the passes and is not itself signed; recount it. Blocks not yet read and passes we missed are our gaps, counted against us on the same page, never a fact about the address. ## About this item Name your receiving address (the wallet query parameter; Base by default, Polygon with network=eip155:137, other supported EVM chains with network=, Solana with network=solana) and for 30 days the store's rounds read every USDC transfer in and out of it, straight off the chain, four times a day: each pass picks up at the block after the last one and is signed alone, so the month stitches into one continuous block range and any single pass can be quoted without the rest. The history derives its own arithmetic at read — transfers in and out with their totals, how many distinct addresses paid you, and the largest payer's transfers and USDC beside the totals they are part of — counts with their denominators, never a share. A pass the rounds miss is a gap counted against us on the same page. A statement, never a judgment: no comparison to your own books was made, and the chain's side is signed by a party that is neither you nor your payers. Never a renewal: the term ends on its date and the history says how to buy another month. - **id:** `operator_statement` - **price:** $21 fixed, covering a 30-day term, one payment; nothing here charges again by itself, ever — there is no mechanism that could - **fulfillment:** delivered instantly - **buy:** `GET https://scvd.store/api/buy/operator_statement?wallet=` (USDC over x402 v2 on Base, Polygon, Arbitrum, World, Solana, Arc (Circle Gateway), or USDC over MPP (evm/charge) on Base for every shelf item, every publication page and the commission desk) - **required inputs:** `wallet` — fill the `` slot above before paying. The bare door `GET https://scvd.store/api/buy/operator_statement` quotes free and refuses the paid request without it; no money moves. - **sample:** https://scvd.store/samples/operator-statement.json - **does not prove:** What any transfer was for, who the paying addresses are, or anything outside the block range, asset and chain the pass names. The summary on the history is arithmetic over the passes and is not itself signed; recount it. Blocks not yet read and passes we missed are our gaps, counted against us on the same page, never a fact about the address. House rules: give the address in the wallet query parameter: a 0x evm address on a supported evm chain, a base58 pubkey on solana. usdc on base by default, polygon with network=eip155:137, other supported evm chains with network=, solana with network=solana — one chain per statement, named on every pass with the unit its range counts in (blocks, or slots on solana); four reads a day for 30 days, each from the block after the last pass to the chain head, never more than the engine's eleven-hour ceiling in one read; a missed pass is closed by the next one where it can be and counted against us where it cannot; counts and totals cover every block read; per-pass payer tallies are capped at a named number of distinct addresses and say when they stopped naming; public chain state only: nothing of yours is fetched, and the address is the whole input; the history url is free to read forever and ends on its own date; nothing here renews itself. > A month of your till, read off the chain by somebody who is not you. The page is bought; what it shows never is. Optional next work: A customer or internal reviewer needs a shareable record of what your public payment endpoint did over time.
