01 · How it works
Three cards. One stake. Winner takes both.



01
Pick three graded cards
Your Collector Crypt slabs are your deck. Three of them make a squad.

02
Stake one
Your stake is locked in a Solana escrow and matched only with a card worth the same, within ±10%.


03
Winner takes both
TCG rules: energy, attacks, weakness. Three points wins the duel — and both cards.
02 · Under the hood
Real cards, real rules, no take-backs.
Every slab stays vaulted
Cards never leave Collector Crypt custody — only ownership moves. Redeem the physical slab anytime.
// commit–reveal seed commit sha256(secret_a) ← you commit sha256(secret_b) ← rival seed = sha256(a ‖ b ‖ duel) replay(seed, moves) → same game ✓ settle(duel, winner) → both cards to the winner ✓
Every coin flip is provable
The seed comes from both players' committed secrets. Same seed and same moves give the same game — any duel can be replayed.
Your vault, ready to duel
Load the Collector Crypt cards in your Solana wallet. Practice with any of them; stake the ones the escrow accepts.
Nobody can run with your card
The referee can only name a winner. No result before the deadline? Anyone can send both cards home.
Stake a slab. Play the duel. The winner takes both.
