SETZ is a digital collectibles platform on the Base network. It issues limited-edition box sets that are sold onchain; each box contains packs, and each pack contains cards. Holders can keep a box sealed, trade it, or open it to reveal the cards inside. Each card is backed by a basket of liquid ERC-20 tokens held in an onchain vault. The basket's composition is set per release, and a card can be redeemed for its share of the underlying tokens, which are released to the holder when the card is burned. Cards and sealed boxes are transferable and tradable on secondary marketplaces. SETZ is the platform's native token and is one of the assets held in the collectible vaults, alongside other ERC-20 tokens selected per release. It is an ERC-20 token on Base with a total supply of 100,000,000,000, of which 15,000,000,000 is held by the token contract.
