Backend
API Surface
The first public shape of Backend APIs for order intake and matching read models.
Base path
The Backend MVP uses a versioned API under /v1. Exact endpoint names can evolve, but the domain boundary should remain stable.
Write paths
The first critical write path accepts a wallet-signed limit order, verifies it, reserves collateral, and stores it as an Open Order.
Read paths
Read paths expose market Order Books, user open Orders, reserved collateral, Fills, and Trade history from Backend-owned state.
