Ultra-High Performance Decentralized Exchange - 434M+ orders/sec with sub-microsecond latency

LX

Ultra-high performance DEX with 434M+ orders/sec on Apple Silicon.

LP Specifications: This implementation follows LP-9000 DEX Series - see LP-9000, LP-9001, LP-9002, LP-9003

Overview

LX is a planet-scale, fully on-chain decentralized exchange built on Lux Network, combining ultra-low latency matching, quantum-resistant security, and support for global markets in a unified system. LX runs as a dedicated Lux L2 chain that shares consensus and finality with the main network. Validators stake LUX to operate DEX nodes (lxd), with settlements committed via Warp messages.
