Circles

On-chain programmable spaces, gated by NFT ownership

Circles is a programmable access layer built on Octra’s on-chain execution environment. Each Xpectrum collection gets one Circle: a sealed, collection-wide space where holders interact using their NFT as a key.

What a Circle is

A Circle is an isolated execution environment deployed on Octra. It runs AML/OCTB bytecode and can call on-chain contracts directly. Circles are not databases or off-chain servers. They are first-class on-chain programs with their own state and logic.

On Xpectrum, each collection has one Circle deployed alongside it. Holding an NFT from that collection grants access. The NFT is the key. No separate token, no allowlist.

Circles are live on Xpectrum. The current implementation is collection-wide: one Circle per collection, accessible to all holders.

How access works

When a holder enters a Circle:

1. The Circle contract calls get_token_info(token_id) on Xcollection to verify ownership
2. If the caller owns a token from the collection, access is granted
3. The holder interacts with the Circle’s on-chain state directly from their wallet

No backend, no session tokens. Access is verified at the contract level on every interaction.

What creators can build with Circles

Circles expose programmable logic that creators configure at deploy time:

• Token-gated communities - discussion, voting, or coordination spaces accessible only to holders
• Holder rewards - on-chain claim mechanics tied to NFT ownership
• Collection governance - holder votes recorded as on-chain state
• Gated content distribution - content addressable on-chain, unlocked by token ownership verification

On-chain calls

Circles can call other contracts on Octra using the call(address, "method", args) primitive. A Circle can:

• Read state from Xcollection (verify ownership, check token metadata)
• Interact with Xmarket (query listing state)
• Call any other XNS-1 compliant contract on the network

WASM execution inside Circles is rolling out. This will expand the range of logic that can run in a Circle beyond AML/OCTB bytecode.

Future direction

The items below are planned or exploratory. None are live and none have a confirmed timeline.

The current implementation is collection-wide. Future work may explore per-token Circles, where each NFT has its own isolated state, enabling richer token-level programmability. Additional areas under consideration:

• Circle-to-Circle cross-collection calls
• Creator-upgradeable Circle logic post-deploy
• Integration with Octra’s FHE layer for private state

These depend on Octra network capabilities that are still maturing. This page will be updated as features reach devnet or mainnet.
