How It Will Work
No blind trust. No stock-photo listings. Every card that enters the marketplace passes through a GRADEX device first.
01 — Scan to List
Sellers scan the exact card they are selling. The spectral fingerprint and grade are attached to the listing — not a stock photo, the actual card.
02 — Verified On-Chain
Each graded card carries an on-chain certificate on Solana. Anyone can verify authenticity and grading history before buying.
03 — Protected Settlement
On delivery, the buyer re-scans the card. Spectral data must match the original listing scan — then the trade settles.
04 — Reputation That Travels
Every completed trade builds a seller's verifiable track record, anchored to their device and on-chain history.
