The marketplace shows cards listed for sale by simulated sellers. You can browse by sport, filter by price range, and buy cards directly into your vault using your wallet balance. Prices are based on real market data with small seller-set discounts or premiums.

Each listing is priced relative to the card's estimated market value. Some sellers offer deals (5-15% below market), while premium cards may carry a slight markup. Look for the "Deal" badge for cards priced below market value.

Yes! Cards in your vault can be listed for sale. You set the price, and when a simulated buyer purchases your card, the proceeds go to your wallet balance minus a 5% marketplace fee.

Buyback (in your vault) gives you an instant 90% of fair market value. The marketplace lets you set your own price and potentially earn more, but the card may take time to sell. The marketplace also lets you buy specific cards you want.
