How it works

Three steps. No shipping until you want it.

01 · Pick a pack

Choose a tier

Starter to Grail. Every pack returns 99% of its price in expected value, and the full odds table is public before you pay.

02 · Open it

Pull a real slab

A verifiable random draw assigns you a PSA‑graded card that is already sitting in the Vault. The reveal is instant; the proof is onchain.

03 · Decide

Keep, cash out, or ship

Hold it in the Vault for free, sell it back for 95% of market in one tap, list it on OpenSea, or have PSA ship it to you.

The odds are the product.

Every pack shows its live odds table and expected value before you buy: 99% of the price, with the remaining 1% funding the draw and the sell‑back floor. Inventory comes from the PSA Vault, so the table only changes when slabs enter or leave.

Draws use verifiable randomness. The request and result are written onchain, so a pull can be checked by anyone, including you.

Questions

Is the card real?

Yes. Every pack maps to a specific PSA‑graded card with a cert number, physically held in the PSA Vault. The token is a 1:1 claim on that slab.

How is market value set for the 95% sell‑back?

From recent PSA‑graded sales for the same card and grade, refreshed continuously. The number you see on the reveal is the number you're paid against.

Can the house rig a pull?

No. Draws use verifiable randomness recorded onchain, and the odds table is fixed at the moment you buy.

What does it cost to ship?

Storage and insurance in the Vault are free. Shipping follows PSA Vault's withdrawal fee ($1.99 under 90 days, $4.99 after) plus carrier cost.

Is this live?

Not yet — this site is a working concept demo. Pack opens, sell‑backs and the Vault run in your browser with demo credits; nothing touches a wallet or a real slab.

Your first pack is a real slab.
