Spectrum's progress report on Octra devnet. Contracts are live. SpectrumNFT: Handles minting, transfers, approvals, and royalty enforcement on every settlement. SpectrumMarketplace: Handles listings, offers, buys, fee distribution, and withdrawals. Tested end-to-end: minted a token, listed it. All confirmed on-chain in the same session. Next test: executing the first live buy transaction on devnet to verify settlement flow. A few things we learned building on Octra (for anyone else crazy enough to do this): Checkpoint/commit ordering matters. State mutation has to happen before the transfer call, not after. This doesn't throw errors. You only find it by diffing execution receipts across failed transactions and tracing what actually committed. Nested map collisions are silent. `map[int]map[address]int` has an edge case where `offer_id` and `token_id` sharing the same integer value in the same epoch writes to the wrong key. No error. Just wrong state. Had to restructure the key schema to separate the namespaces. No local fork environment. Every compile, a live deploy. Every bug, a devnet bug. You get good at reading receipts fast. Next up: the part we actually built Spectrum for. Private bids. Hidden reserve prices. Anonymous trading. Octra's encrypted state makes all three possible natively. This is why we're here.
