Quick Solidity pre-audit check, $0.90 USDC on Base

Quick Solidity pre-audit check, $0.90 USDC on Base: send source or a verified contract address + chain; the same automated engine returns the verdict (grade, score, security and owner-trust risk), severity counts, the top 5 findings with location and fix, and owner powers found (mint, pause, blacklist, fees, upgrade). Triage, not a human audit; failed runs not charged. Every finding with code and detail: POST /v1/audit ($99). By DevX.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
