A card is a moment from your season that a fan can own.

Each card shows one moment: a game, a race, a bout, a match, with the stat line that made it worth keeping, the athlete's photo, and her Seal as it stood that day. It is minted as a token on Base at the moment a fan buys it, in an edition whose size is set in advance and never enlarged. Unsold copies are burned when the window closes, so the edition size you see is the number that exists.

The athlete makes the card, sets the price above the $20 floor, and keeps 80% of every first sale. When a card is resold, the athlete gets 10% of the resale for as long as the card exists. Nobody has to invoice anybody; the payment processor pays each party directly.

A fan holds the card in a collection created at sign-up and secured with a passkey. Cards trade on Next Up's own marketplace. If the company ever stopped operating, the contract releases transfers so holders can take their cards anywhere; that clause is in the code and cannot be turned off.

Editions come in five materials, from paper to platinum, and the material follows edition size: the smaller the edition, the closer to the moment.
