LX DEX - Planet-Scale Decentralized Exchange

🚀 World's Fastest Decentralized Exchange

LX DEX achieves 581,564,408 orders/second with 597 nanosecond latency - faster than centralized exchanges while maintaining complete on-chain execution with instant finality.

🎯 Key Features

• Planet-Scale Performance: 581M+ orders/sec, 597ns latency
• On-Chain Order Book: Complete on-chain execution with atomic settlement
• Quantum-Resistant: Post-quantum cryptography from day one
• Multi-Backend: Automatic GPU/C++/Go optimization based on hardware
• Advanced Orders: Iceberg, bracket, pegged, TWAP/VWAP algorithms
• DeFi Integration: Margin trading, vaults, lending protocols
• Multi-Protocol: WebSocket, gRPC, FIX 4.4, REST APIs

💻 Client SDKs

Go SDK

import "github.com/luxfi/lx/sdk/go/client"

client := client.New("localhost:8080")
order := &Order{
    Symbol: "BTC-USD",
    Side:   Buy,
    Price:  50000,
    Size:   1.0,
}
trade, err := client.PlaceOrder(order)

Python SDK

from luxfi_dex import Client

client = Client("localhost:8080")
order = client.place_order(
    symbol="BTC-USD",
    side="buy",
    price=50000,
    size=1.0
)

TypeScript SDK

import { LXClient } from '@luxfi/lx-sdk';

const client = new LXClient('localhost:8080');
const order = await client.placeOrder({
    symbol: 'BTC-USD',
    side: 'buy',
    price: 50000,
    size: 1.0
});
