PokéVault is a Pokémon card pack-opening experience built on three promises: every card's odds are shown before you buy, the server commits the result before you open, and you can mathematically verify every pull afterwards. Keep your cards or claim them — never sold back for money.

How it earns trust
Before you open, we publish the SHA-256 hash of a secret seed. After you open, we reveal the seed. Hash it, re-run the math, and confirm the result was fixed in advance — never rigged.
See the proof →The pack shakes, tears, and bursts — and the spectacle is scaled to what you actually won. A Common gets a clean flip; a Mythic gets the full screen-flash moment. Never a fake near-miss.
Open a pack →Every card's exact probability is on the buy screen, colour-coded by rarity, summing to a verifiable 100%. The odds you read are the odds the server honours.
Read the odds →How it works
Browse the store and see every card's odds, summing to 100%, right next to the price.
The server commits a hashed seed, rolls, and records the result — before your browser animates anything.
A rarity-scaled animation reveals the exact card the server already decided.
Paste the revealed seeds into the verifier and reproduce the result yourself.
No hidden odds
Here's the headline breakdown for the Great Ball Pack. The full per-card table lives on the pack page — nothing is hidden behind the purchase.

We foreground rarity, sets, and completion — not dollar amounts. Cards can be kept digitally or claimed as physical copies, but there is no sell-back, anywhere, by design. All currency in this prototype is clearly-labelled demo coins, for entertainment only.
