iOS · Real vaulted cards · Provably fair

GRAIL HUNTERZ

by Caldarus Labs

Rip packs of real trading cards from your phone. Every card in a pack is a real, vaulted card we own. The odds are published before you buy, every draw can be verified after, and you choose what happens next — keep it in the vault, ship it home, or sell it back instantly at a transparent price.

The Hunt

How it works

01

Pick a pack

Eleven tiers, $1 to $2,500. Before you buy, you see the exact odds table and the exact pool of cards the pack draws from.

02

Rip it

The draw is provably fair: it is committed to before you buy and you can verify it yourself afterwards, with an independent open-source verifier.

03

Your cards, your call

Every pull is a real card in our vault, in your name. Keep it vaulted, or have it shipped to your door.

04

Or sell it back

Instant buyback at a transparent quoted price, whenever you choose. Proceeds can be withdrawn to your bank.
