# What is Top Market?

Top Market is a platform for buying and collecting physical trading cards. You get cards by buying and opening packs, then choose to keep each card or accept Top Market's buyback offer and sell it instantly. Once you keep a card, you can also request delivery of the physical card.

#### Top Market at a Glance

Each line points to the page that covers it in full.

* **Packs:** Every pack shows its odds and full prize pool before you buy, and every pull can be checked on-chain.
* **Jackpot:** Every pack you open also has a 0.1% chance at the site-wide pool. See Jackpot.
* **Keep or sell:** Don't want the card you pulled? Accept the buyback offer and sell it right away.
* **Collection and delivery:** Your cards are held for you until you ask for the physical card.
* **Marketplace:** Choose the exact card you want, or sell your own at a fixed price or by auction. 
* **Earn:** Cards you aren't selling yet can earn yield in the reveal pool, and they stay yours until another user keeps them.
* **Raffle:** One rare card, split into low-priced numbers. If every number sells by the deadline, an on-chain draw picks the winner.
* **Referrals:** Invite friends and earn 0.1% of every purchase they make.
* **GP & CP:** Two kinds of points that track what you spend and how you take part.

Every card in your collection is a physical card graded by a professional grading company (for example, PSA) and held by Top Market. If you are new, start with Account and Balance to sign in and add funds.
