This machine is Collector Crypt's. The cards, the vault, the odds and the randomness are theirs. Playset hosts it and takes nothing yet; the fee will be shown here before it is charged. Odds epic 1% · rare 4% · uncommon 20% · common 75%. Expected value after our fee $102.00 (Collector Crypt's own figure $105.01). Buyback 90% for 72 hours. Verify any pull: its memo and roll against their VRF program.
You sign one USDC transfer that Collector Crypt builds; nothing else is signed. Open the pack within two hours or it refunds itself.
