Demotrionn DEX
Multi-chain DEX interface featuring advanced charting tools and high-frequency data indexing for pro traders.
- React
- GraphQL
- PostgreSQL
The Problem
Pro traders needed a multi-chain DEX UI with reliable charting and fast data indexing rather than laggy generic interfaces.
Main-thread overload from unthrottled websocket updates was a primary risk for multi-pair views.
Tech Stack & Architecture
React frontend with GraphQL data layer and PostgreSQL-backed indexing for high-frequency market and pool data.
Subscription lifecycle, update coalescing, and chart rendering strategy were treated as first-class design constraints.
Key Results / Business Outcome
Built a multi-chain DEX interface with charting and indexing suited to professional trading workflows.
The UI remains responsive under concurrent pair subscriptions when feeds are managed correctly.
