CatchBackについて
CatchBack is a digital pack-opening platform: users build or buy packs, openings resolve through verifiable randomness, and the physical cards pulled are held in an insured vault where they can be kept, shipped, listed on the platform marketplace or sold back. Buyback is 90% of appraised value within five minutes of a pull and 80% afterwards with no deadline, marketplace trades charge a flat dollar to each side, and the platform currency CatchCoins converts to dollars one to one. Packs come from platform templates or from card mixes users assemble themselves.
It maps trading-card ownership onto on-chain receipts backed by an offline vault, adding physical custody and buyback market-making to a pure NFT marketplace, and settling in minutes where an auction house takes days. The buyback price sits a fixed 10% to 20% below appraised value, the catalogue concentrates on sports and collectible cards, and buyback capacity for illiquid cards rests on the platform's own balance sheet.

CatchBack's product is pack opening backed by vaulted physical cards. Users build or buy packs, pulls are decided by verifiable randomness, and the cards sit in an insured vault where they can be held, shipped, listed on the platform marketplace, or sold back at a buyback price. Buyback runs at 90% of appraised value for five minutes after a pull and 80% afterwards with no expiry; marketplace trades charge a flat one dollar to each side, and the platform currency CatchCoins converts to dollars one to one. The buyback price is effectively a put: promising to absorb inventory at ninety and eighty percent of appraised value requires the balance sheet to hold cards through a drawdown, otherwise spread income is eaten by write-downs. Wider categories dilute single-card risk but push valuation from comparable sales toward subjective grading, which invites disputes.
CatchBack widens the catalogue from sports cards into other collectibles, uses institutional vaulting and insurance to support larger packs, and runs the buyback spread as a hedgeable market-making book.
