PUPMKT - Evidence-first resale for games, cards and collectibles

Hi Product Hunt, I am Stephen, founder of PUPMKT. On most resale sites a listing is a story the seller tells. Here it has to carry evidence: photos of the exact item, its identifiers, its condition, one listing per physical thing. Browsing is open, sellers open today, purchases follow. Built in six months with GPT-6 Astra, Codex and Claude under a signed verification chain, every product decision mine. Tell me where the evidence rules feel like friction and where they feel like trust.
