Building a Real-Time DEX Trade Aggregator with WebSockets

Technical walkthrough of how we aggregate DEX trades across Uniswap, SushiSwap, PancakeSwap, and 20+ DEXs into a single unified feed.

DEX data sources are fragmented, so we built adapter workers per protocol and chain.

Each adapter emits normalized trade events into our streaming backbone, where deduplication and enrichment happen.

Clients subscribe through WebSocket channels filtered by chain, pair, wallet, or event type.

The result is a low-latency feed that powers our tracker, alerting systems, and developer API endpoints.
