Don't trust.
Verify a pull.
Every pack is sealed before you pay and checkable after you open it — by you, not just by us. First how it works, then the tool to check your own pack.
The instant your pack is created, we generate a secret server seed and show you only its SHA-256 hash — the commit.
From that moment the contents are locked in. Open it in five minutes or in six months — the hash proves nothing was changed after the fact.
Right after payment, your browser generates your client seed and sends it once our commit is already saved. It's mixed into the draw, so the outcome isn't ours alone to set, and it can't be changed afterwards. On older packs bought before this, you can still type your own under "Advanced" before opening.
The real server seed is revealed. Recompute the hash yourself with the verifier below and confirm it matches the commit you saw before you ever tapped open.
Every pull has its own value in Coins, estimated by us from market trends: sell it back instantly for 75% or ship the real card from your Binder. Can't be sourced? Full reference value, refunded.
We fetch the seed, commit and pool for that pack; the calculation still runs in your browser. No pack yet? .
Current algorithm v5 (older packs: v3, v2, v1). Every pack records the version it was drawn with, and the verifier recomputes it with that one.
