Receipt Verifier — a Base transaction hash in, a normalized verified receipt out: payer, payTo and amount from the USDC Transfer log, asset and network, settled status and confirmations. When the payTo is this fleet's own and the amount matches a priced route, routes at that price are listed as candidates — an amount alone never proves which route was called. Unknown transactions error honestly, unsettled. Use this when someone claims they paid and you want the chain's version. Base only.
