Orders are escrow: buy orders lock SLN and sell orders lock tokens directly in the contract; takes fill in full at the limit price — no middlemen, the book is auditable by anyone on-chain.
· Order-book mode = decentralized spot limit matching: contract escrow, full fills, atomic on-chain DvP (delivery-versus-payment) settlement.
· Complete KYC before taking orders (compliance: tokens only move between whitelisted addresses).
· Demo simplification: full fills only; partial fills and the matching engine (in-house matching) ship with mainnet.
