CardBox

CardBox is a trading-card-game (TCG) RWA infrastructure platform offering blind-box card pulls, card trading, and instant buyback, with a longer-term positioning of providing underlying capabilities such as physical custody, digital rights confirmation, a liquidity network, and trade matching for the card market. The platform partners with the authoritative grading agency CGC to embed institutional-grade authentication into the Web3 flow, and operates distributed bank-grade vaults in the United States, Japan, and South Korea for local custody and full insurance of physical cards.

Mechanically, each authenticated card stored in the vault is minted as a BEP-721 digital-twin NFT on BNB Chain, with the physical item remaining in the vault while ownership circulates on-chain; the platform integrates real-time data oracles to estimate a fair market value for each card from recent sales on markets such as eBay, PWCC, and Goldin. Users can earn a 1% share of blind-box sales via Listaking while their card waits to sell, and secondary-market sales carry a 2.5% fee. Since its beta release, CardBox has accumulated over 20000 registered users and more than 100000 on-chain interactions on BNB Chain.
