The ownership layer for on-chain objects. Formally verified contracts, permissionless launches, and collections that live on the chain itself rather than pointing at it.
TITLE DEEDS
FOR ON-CHAIN
OBJECTS.
Ownership that cannot change hands is not ownership, so the marketplace came first. It is the first surface, not the whole of it. Underneath is a standard, a verified contract set, and storage that belongs to the chain rather than to us.
Generate, store, commit. Provenance before the first mint.
The stack
Five layers, one standard
THE STANDARD
XNS-1 · formally verifiedXNS-1 is the token standard the rest is built on, and it is machine-checked rather than merely audited. Every contract in the stack carries its own verification certificate: the collection, the whitelist, the market, the factory. What the contract does is what the certificate says it does.
LAUNCH
XuperFactory · commit-firstA full collection deploys from your own wallet in one transaction, for a 1 OCT launch fee plus network costs, with no approval step and no involvement from us. Multi-phase drops with guaranteed, FCFS and public rounds, per-wallet caps, bulk whitelists. The collection hash is committed on-chain before minting opens, so tampering is visible forever and rarity sniping is impossible by construction.
STORAGE
Circles · oct://Collections live in Octra circles: artwork, metadata and trait layers, oct:// all the way down. No IPFS, no pinning service, nothing to keep paying for to stop the art disappearing. Generative collections store the layers rather than baked images and the token is composited live from chain state.
MARKET
XmarketListings, individual offers and collection-wide bids, with royalties enforced at the contract level rather than by policy. Proceeds are pull-based: recipients claim in a separate transaction, so a payout can never be taken down by a failure further along the same call.
PRIVATE
Render typesOnce rendering is a view of chain state, an image is only the first render type. A token whose content is a running program has the same shape as one whose content is a PNG, and the standard does not have to change to carry it. Private, holder-gated content sits on the same shape and is in development.
For Creators
From art to live,
in one transaction.
Bring your art
Composite from trait layers for a generative drop, or upload prerendered art. The wizard writes the metadata and computes the provenance hash for you.
Set the terms
Supply, phases (guaranteed, FCFS, public), pricing, per-wallet caps, royalties, whitelists in bulk. Stored on-chain by default, or point at your own host if you would rather.
Deploy and keep the keys
One transaction from your own wallet, a 1 OCT launch fee plus about 0.2 OCT of network fee. 97.5% of every mint is yours, royalties are enforced on-chain on resale, and we hold no admin key over the collection afterwards.
Four ways to build a collection
Composited
Generative, from trait layers
Single
One image, whole collection
Tiered
Grouped by rarity tier
Unique
A distinct image per token
An image is only the first render type. The same shape holds a running program.
Built in public.
Verifiable by anyone.
Contracts, certificates and drop announcements, in the open.
