How it is built

Web
Next.js application for this site and the signed-in demo, calling the API through a same-origin proxy.
API
NestJS service with input validation on every endpoint and a published OpenAPI specification.
Data
PostgreSQL for records and Redis for rate limits shared across instances.
Financial core
A shared decimal library for pricing, ledger rules and order states, used by the calculator and the order preview alike.
Provider adapters
Typed interfaces for market data, execution, custody, banking and identity. Simulators implement them today.
