VETA VETA Trading Platform

Section titled “What’s included”

Architecture

Section titled “Architecture”

The platform is a collection of Deno microservices connected by a Redpanda (Kafka-compatible) message bus. The React frontend talks to a single API Gateway — the only service the browser can reach.

Frontend → Gateway (WebSocket + HTTP) → Redpanda bus → Services

See the Architecture page for the full service map.
