ONCE SOLD,IT’S GONE.
A market for digital objects
with one primary sale.
SOLD / 000
NOTHING LISTED YET.
The contract is not deployed. The first object will be listed once it is.
THE PROTOCOL
Four rules. The contract enforces the first three. We say the fourth out loud.
- 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.
- 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.
- 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.
- 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.
