CardMart.

CardMart is a marketplace for trading cards, starting with Pokémon and One Piece, built on Solana. Its starting point is the question every collector asks: what is my card really worth?

Every card has a price page by grade (PSA, BGS, CGC or ungraded) with price history and a comparison against eBay and TCGplayer. Sales go through escrow: the buyer pays in, a warehouse inspects the card, and only then is the seller paid. On top of that come live auctions with an anti-sniping rule, and an AI buying agent that watches listings for a card, grade and maximum price for you.

Cards kept in CardMart's vault are represented on Solana as 1-of-1 tokens, digital twins of the physical card that can be traded and later redeemed for delivery to your door.

CardMart is at an early stage: it currently runs on Solana devnet with test SOL, and payments and settlement are simulated while the team builds towards a mainnet launch.
