Xpectrum is live on Octra mainnet. This page draws a hard line between what is shipped, what is actively being built, and what is exploratory. Items in Horizon have no committed timeline.
Contract changes are recorded in the contract changelog, which is the place to check whether something that affects you has moved.
Shipped
Every contract below is deployed on mainnet and formally verified.
Building now
Active work with a clear path to shipping:
- xpress, open: publish the launch engine to npm and open-source the repository, so anyone can generate, hash, deploy and independently verify a collection without our app.
- Holder-gated private content: rebuilding it so that only the current on-chain owner can read a token’s private content, with no third party in the path. The previous approach is withdrawn and is not documented. See Circles.
- Auctions: Xauction is built and formally verified, with the token escrowed at creation. Not yet deployed.
- Batch listing: list multiple tokens from a collection in one transaction.
Horizon
Exploratory. None are live, none have a confirmed timeline, and several depend on Octra capabilities that are still maturing.
- Private collection state with FHE: sealed bids and private metadata on Octra’s fully homomorphic encryption layer.
- Richer Circle programmability: more expressive on-chain logic, including per-token state where each token carries its own isolated logic, and cross-collection interaction between Circles.
- Cross-collection bundles: list or bid on a set of tokens from different collections in one transaction.
Network dependency
Horizon items track Octra’s own progress, particularly the FHE toolchain and the cross-contract gas model. We follow those upstream and move items into “Building now” only when there is a real path to shipping.
