**Current Price**: $600
**Contacts**: https://t.me/dan_cryptoscan

What you get:

- Free setup into your hosting
- Free help to integrate app to your server
- Full access to the codebase and code updates
- Free updates for app, you can request for free updates via access to issues
- Full access to Project Time tracking by developers

## Features

- Real-time arbitrage opportunity detection
- WebSocket-based price updates
- Multi-exchange support
- Network-aware transfers
- Spread filtering capabilities
- Support for both spot and futures markets

## Architecture

The service consists of several key components:

### Network Management (`getNetwork.ts`)
- Maintains real-time network status across exchanges
- WebSocket connection to network updates
- Tracks deposit/withdrawal status and fees

### Arbitrage Detection
Two implementations available:
- Modern implementation (`getArbitrageNew.ts`) using BigNumber for precise calculations
- Classic implementation (`getArbitrage.ts`) with simpler order matching

### WebSocket Server (`websocket-server.ts`)
- Provides real-time updates to clients
- Supports spread-based filtering
- Built using Hono framework

## Installation

```bash
# Install dependencies
npm install

# Start the service
npm start
```

## Environment Variables

Create a `.env` file with required configuration:

```env
# Add any required environment variables here
```

## WebSocket API

### Connecting

Connect to the WebSocket server:
```javascript
const ws = new WebSocket('ws://localhost:3000');
```

### Message Format

Received messages follow this structure:
```typescript
interface ArbitrageMessage {
  exchangeFrom: string;
  exchangeTo: string;
  symbol: string;
  network: string;
  spread: number;
  buyPrice: number;
  sellPrice: number;
  totalAmount: number;
  totalBuyUSD: number;
  totalSellUSD: number;
  format: "hedge" | "transfer" | "delayed";
  withdrawFee: number;
  depositFee: number;
  isWithdrawEnabled: number;
  isDepositEnabled: number;
}
```

## Development

The project uses:
- TypeScript
- Bun runtime
- BigNumber.js for precise calculations
- Hono for WebSocket server
- Semantic Release for versioning
