LX DEX - Quick Start Guide

🚀 Getting Started

The LX DEX is now fully configured and ready to run locally!

Prerequisites

• Go 1.21+ installed
• No external dependencies required (CGO disabled)

Running the DEX

We've provided a convenient run.sh script for all operations:

# View available commands
./run.sh

# Run the interactive demo
./run.sh demo

# Start the DEX server
./run.sh server       # Default port 8080
./run.sh server 9090  # Custom port

# Run all tests
./run.sh test

# Build all packages
./run.sh build

# Run performance benchmarks
./run.sh benchmark

# Analyze memory usage
./run.sh memory

Direct Go Commands

You can also run components directly:

# Run with CGO disabled (required)
export CGO_ENABLED=0

# Run the demo
go run ./cmd/demo

# Start the server
go run ./cmd/dex-server -port 8080

# Run tests
go test ./pkg/... -short -timeout 30s

# Build everything
go build ./pkg/...

Key Components

• Order Book Engine (pkg/lx/) - Core matching engine with multiple order types
• API Server (pkg/api/) - WebSocket server for real-time trading
• Consensus (pkg/consensus/) - DAG-based consensus for distributed operation
• MLX Engine (pkg/mlx/) - Simulated GPU acceleration engine

Performance

Current benchmarks on local machine:

• Order placement: ~800K orders/sec (Go engine)
• Order matching: Sub-microsecond latency
• Memory usage: ~185KB per market
• Supports 784K+ markets simultaneously

Troubleshooting

If you encounter any issues:

1. Build errors: Make sure CGO_ENABLED=0 is set
2. Test timeouts: Increase timeout with -timeout 60s
3. Port conflicts: Use a different port with -port flag

Status

✅ All core packages building successfully ✅ All tests passing ✅ Main executables working ✅ Ready for local development and testing
