A pack's card order is fixed by a server seed we commit to — as a hash — before anyone opens, and reveal once the pack is fully opened. Here's the model, and what it does and doesn't prove.
When a pack goes live, our server generates a secret seed and publishes its hash + the assignment hash — locked in before anyone opens.
The seed deterministically shuffles the pack's card order. That order is fixed at publish — we can't reorder, swap, or remove a card once selling starts.
Once the pack is fully opened, the original seed is revealed, so the hash you saw earlier proves it was never swapped.
Re-run the exact shuffle yourself on the /verify page. Matching hashes prove the pack's contents and order were fixed before sale and never altered.
What this proves, and what it doesn't. Matching hashes prove a pack's contents and their order were locked in before it went on sale and were never altered afterward. Which position in that order a given buyer receives is assigned at purchase and is not covered by this proof.
Complete transparency on drop rates
A card's rarity is what it is worth next to the price of the pack it comes from, so the same card can be Rare in one pack and Common in a pricier one. Each pack prints its odds for every rarity, counted from the cards actually inside it. A card you have already opened keeps the rarity it showed you.
Unbiased random selection
Every pack is shuffled with a cryptographically secure random number generator (Node.js crypto), so no outcome is weighted or hand-picked. The seed behind each shuffle is committed as a hash before the pack goes on sale and revealed once it's fully opened — so you can check for yourself that the pack's contents and their order were locked in up front and never changed.
Clear valuations, no hidden fees
Instant Offer shows valuation sources (e.g. recent comps) and our take rate. You'll always see your net payout before accepting.
