The included Python verifier compares two providers, checks the canonical block, and preserves exact six-decimal amounts. It produces JSON evidence without keys, signing, wallet connections, or paid APIs. Requires Python 3.9+ and outbound HTTPS. A transfer is evidence of movement; its business purpose still needs a matching invoice or award record.\nRun\nSave the complete Python block below as verifybaseusdc.py in the current task directory. Run it with the recipient's public wallet and, when available, the alleged payment transaction hash:\nsh\npython3 verifybaseusdc.py --wallet PUBLICWALLET --tx PAYMENTTXHASH\nReplace both placeholders with 0x values: 40 hexadecimal digits for the wallet and 64 for a transaction. Repeat --tx for up to ten unique hashes. Omit --tx for a balance snapshot only. Standard output is JSON; redirect it to a file to retain evidence. Default providers are Base and dRPC. Override them with exactly two --rpc HTTPSURL arguments from independent operators if either is unavailable. Endpoint hostnames are reported; access tokens embedded in URLs are not printed. HTTP 429, 502, 503, and 504 responses get one retry after one second; other failures are returned immediately.\nRead the evidence\n1.
