Prices are the cheapest card listed on Collector Crypt that meets each grail, refreshed every few minutes. The vault buys whichever card meets the grail when it can afford it.

Questions
Are these real cards?
Yes. Each card is a professionally graded card (PSA, CGC, BGS) stored in an insured vault and represented by an NFT: Collector Crypt cards on Solana, Courtyard cards on Polygon. Whoever holds the NFT can trade it or redeem it for the physical card.
Which card does the vault buy?
The cheapest graded card listed in the coin's category (Pokémon or One Piece) at the time the vault can afford it: on Collector Crypt's marketplace, or on OpenSea for Courtyard. The keeper checks each card's category, so a basketball card never ends up in a Pokémon vault.
How do I get a card I win?
Collector Crypt cards are on Solana: open the Giveaways page with the winning wallet and enter your Solana address, and the card is sent there. Courtyard cards are sent on Polygon to the same wallet address that held the coin. Either way you can keep the card, sell it, or redeem it to have the physical card shipped.
How does ETH get from the vault to Polygon?
The keeper announces each withdrawal one hour ahead, and the Registry owner can cancel it. It then bridges exactly that ETH to the card's chain (USDC on Solana for Collector Crypt; USDC or POL on Polygon for Courtyard), buys the card, and records the purchase on Robinhood Chain.
Can I keep the cards in the vault instead?
Yes. At launch you choose what happens to each card: raffle it to holders or keep it in the vault. The choice is permanent. Burning is not offered for real cards.
