The marketplace for graded cards.
Buy and sell PSA‑graded Pokémon, One Piece and sports cards without the slab ever leaving the PSA Vault — 0% OpenSea fee, instant settlement, ship any card home. Paid from the same USDC balance as everything else on OpenSea.
The market
Pokémon slabs listed in the demo — every one vaulted, insured and priced against its insured value.
From the vault, three equal choices.
Every card you buy stays put until you decide.
Keep it vaulted
Stays insured in the PSA Vault and tradeable on the marketplace at 0% OpenSea fee (the vault takes 2% from the seller).

85% of insured value, paid in OpenSea credit within the 72‑hour window. Cash payout available at a lower rate.
85% · 72 hoursShip it home
Redeem the token and the vault ships the physical slab. $5.99 for the first card, $3.00 each additional (US).
From $5.99Built for the rules, not around them.
Odds and EV on the buy screen. Buyback denominated in platform credit by default, cash as a separate lower option. Age gate, per‑user spend limits and a geographic eligibility check that runs before the surface renders.
- Provable randomness with post‑hoc verification on every result
- Self‑service daily spend limit, on by default
- Buyback on insured value — the number is fixed before you open
Questions
Who holds the card?
The PSA Vault. Every listing maps to a specific PSA‑graded slab in custody; the token on OpenSea is a 1:1 claim on that slab, and redeeming burns it.
What is the buyback based on?
The vault's insured value for the card, not a live market price. 85% of that number in OpenSea credit (80% in cash) for 72 hours after the pull — stated on the pack page before you buy.
What does OpenSea earn?
OpenSea's tier ladder is priced for a 93% EV machine; the difference funds the draw, the buyback floor and OpenSea's margin. The marketplace itself charges 0% — the vault takes 2% from the seller.
Is this live?
No — a working concept demo. Draws run in your browser against the published odds; buybacks, listings and shipping update a sandbox balance.
