Overview

The Problem

Collectors can't find real price data. They spend hours checking eBay and SNKRDUNK to price a single card, then drive to a local store or event just to sell it. And there's no easy way to tell which cards are likely to gain value.

The Solution

CardMart puts real market prices, news, and trading in one app. Open it to see what cards actually sell for, then buy or sell raw or graded cards. Keep a card in the vault with an on-chain record, or have it shipped to your home, and see who holds a card and what they trade.

Features

Market

Find cards, compare prices, and follow market activity in one place.

  • Buy & sell

    Browse listings or sell your own cards. Message sellers to ask questions or request close-up photos and videos.

    Raw card:
    A card that has not been professionally checked or scored.
    Graded card:
    A card assessed by a grader. The grading company assigns it a numeric score (such as PSA 9 or PSA 10) and seals it in a protective case.
    Grader:
    A trained specialist who checks a card’s condition and verifies its authenticity.

  • Heatmap

    Each tile represents a card series. Larger tiles mean more trading volume, and the color shows whether prices are rising or falling. Choose 24 hours, 7 days, or 30 days to see changes over one day, one week, or one month.

  • Sale price history

    See completed sales and compare actual prices by card condition and grade, instead of relying on asking prices.

  • Auctions & safe checkout

    Set a start time and reserve price for an auction, or bid in real time. Escrow holds payment until the card arrives and is checked. If it does not match the listing, the buyer can be refunded. Keep the card in the vault or have it shipped to your home.

AI buying assistant

Set the card, grade, and maximum price you want. The assistant watches new listings, compares asking prices with recent sales, and can buy within your limit. It notifies you when it finds a match, so you do not have to monitor listings all day.
