SpendPreflight — trust and verification tools for stablecoin payments, built for AI agents and the people who run them. Base contract signals, not a safety verdict. Basic: bytecode/OFAC. Deep adds owner, paused, supply/decimals, proxy slots, minimal-proxy target and bounded source/deployment evidence. Honeypot/sellability, mint/blacklist powers, liquidity locks, holders and scam lists are unassessed. Missing data stays unknown; never safe-to-buy. Informational, not financial advice.
