Abstract
Atomix is a non-custodial order-book exchange stack for CIP-56 token-standard assets on Canton: an off-chain matching engine with sub-1ms matching paired with on-chain settlement through token-standard workflows, so custody, settlement, and the traded assets stay on the ledger. It is the exchange infrastructure behind Nexode, a prediction market venue in production on Canton mainnet since May 2026. This proposal funds open-sourcing the stack under Apache-2.0, hardening it for third-party operators with a public reference deployment on testnet, migrating settlement to Token Standard V2, building a browser trading frontend, and supporting external adopters, with the largest share of the request gated on independent venues going live on the stack.
