Buy a sealed pack
Pay in USDC for a Courtyard pack or WETH for a classic pack. The Zama coprocessor seals the outcome as an encrypted random number — the pack NFT lands in your wallet, still sealed.
Every pack is sealed on-chain with Fully Homomorphic Encryption — from real graded cards in Courtyard's vault to digital Kanto classics. Nobody — not us, not validators, not insiders — can see or change what's inside until you rip it open. No rigged odds. Just math.

Only the holder can unseal. Zama's threshold KMS decrypts the result and the contract verifies the KMS signatures on-chain before revealing anything.
Courtyard pulls are real graded cards in Courtyard's vault, delivered as NFTs you can trade or redeem. Classic pulls are ERC-721 cards on Polygon.














The coin that powers the flywheel. Its trading fees fill our packs with real graded cards — and every pack sold buys the coin back.
