Understand the draw.

Clear odds, identifiable inventory, and a result tied to the program's settlement rules.

What to inspect before opening

• Price: the cost and quantity you are purchasing.
• Tier weights: the probabilities used by that pack configuration.
• Inventory: card identity, grade or raw status, and recorded value.
• Sellback: the calculation and currency offered for your cards.

How the incoming program works

1. Purchase: the program checks the pack, payment, available inventory, and reserve requirements, then records an order snapshot.
2. Randomness: settlement verifies the configured oracle's randomness proof.
3. Selection: a tier is drawn using its weight, then a card is selected uniformly from the eligible cards in that tier.
4. Ownership: the selected physical inventory record is assigned to the buyer. A batch cannot award the same physical unit twice.

One physical card, one owner

Multiple packs may reference the same inventory record. Owning a card through one pack makes it unavailable through the others. Selling it back can make it available again.

What on-chain verification does—and does not—show

The program can verify its settlement rules and record ownership. It does not by itself prove a physical card's condition, custody, valuation, or delivery. Those remain operational responsibilities.

This guide describes the implementation reviewed for the new release. It is not an independent security-audit certificate or confirmation that the deployed program matches that source.
