NOTHING LISTED YET.

BE THE FIRST TO LIST AN OBJECT

THE PROTOCOL

Four rules. The contract enforces the first three. We say the fourth out loud.

  1. 01

    One listing

    An object is listed once, at a fixed price in ETH. The moment it goes live, its price, content hash and metadata hash are frozen. Nothing can be swapped.

  2. 02

    One buyer

    The first confirmed purchase is the only purchase. The contract rejects every attempt after it. There are no editions and no second copy on this market.

  3. 03

    A permanent record

    The listing becomes a public tombstone: creator, original buyer, price, date and hashes. It can be viewed forever. It can never go live again.

  4. 04

    Not DRM

    The buyer receives the file and can verify it against the committed hash. A file can be copied once downloaded. The sale cannot be repeated.
