CARDS404 is a novel 404 (hybrid) token implementation. Like traditional 404 tokens, NFTs are minted as whole units are accrued by an address. However, with CARDS404, each NFT is minted "face down" and must be flipped to reveal its metadata.

You can think about the CARDS404 mechanism like drawing from an infinite deck of cards. Each time you "flip" a card, you have a chance to draw any card in the deck. This opens up a world of possibilitied for game mechanics, rarity schemes, and more.

In addition to this unique minting mechanism, because the cards are hybrid tokens you can easily sell them into a liquidity pool when you are done playing the game!
