PolyStars

PolyStars is a card-collecting project on Ethereum that organises issuance by season: players connect a wallet, mint cards, and hold them as transferable on-chain assets that can be listed on general NFT marketplaces. Within each season a Stars counter tracks opening and collecting progress, so minting, accumulation and secondary trading form three connected stages. Card content is tied to the season theme, and cards issued in the same season share a numbering scheme that makes season-level searching and price comparison possible on the secondary market.

It addresses the supply cadence problem of collectible NFTs: a single large issuance stacks supply at one moment, secondary prices lose support, and later content has no way to accommodate existing holders. Splitting issuance into seasonal windows and making progress a cross-season measure layers the supply side, so a new season need not dilute older cards. The project has used this structure since its first Genesis season, and secondary trading does not depend on the platform's own matching, with settlement and royalties following contract rules.
