📦 Quick Start

1. Installation

# Install dependencies
pnpm install

2. Configuration

Create a .env file in the root directory with your exchange API credentials:

# Application Settings
NODE_ENV=development
PORT=3000
LOG_LEVEL=debug

# API Access Control (REQUIRED!)
# This key protects all endpoints
API_KEY_ACCESS=your_secure_api_key_here

# Aster DEX Configuration
ASTER_API_KEY=your_aster_api_key
ASTER_API_SECRET=your_aster_api_secret
ASTER_USER_ADDRESS=your_wallet_address
ASTER_SIGNER_ADDRESS=your_signer_address
ASTER_PRIVATE_KEY=your_private_key
ASTER_REST_URL=https://fapi.asterdex.com
ASTER_WS_URL=wss://fstream.asterdex.com

# Hyperliquid Configuration
HYPERLIQUID_REST_URL=https://api.hyperliquid.xyz
HYPERLIQUID_WS_URL=wss://api.hyperliquid.xyz/ws
HYPERLIQUID_WALLET_ADDRESS=your_wallet_address
HYPERLIQUID_PRIVATE_KEY=your_private_key
HYPERLIQUID_TESTNET=false

# Binance Futures Configuration (Optional)
BINANCE_API_KEY=your_binance_api_key
BINANCE_API_SECRET=your_binance_api_secret
BINANCE_REST_URL=https://fapi.binance.com
BINANCE_TESTNET=false

# OKX Perpetuals Configuration (Optional)
OKX_API_KEY=your_okx_api_key
OKX_API_SECRET=your_okx_api_secret
OKX_PASSPHRASE=your_okx_passphrase
OKX_REST_URL=https://www.okx.com
OKX_TESTNET=false

Security Note: The API_KEY_ACCESS is required in the X-API-Key header for all requests to protected endpoints.

3. Start the Application

# Development mode with hot reload
pnpm start:dev

# Production mode
pnpm build
pnpm start:prod

The application will be available at:

API: http://localhost:3000
Swagger Documentation: http://localhost:3000/api

🔐 API Authentication

All trading endpoints require API key authentication using the X-API-Key header.

Required Header:

X-API-Key: your_api_key_access_here

Using Swagger UI

Open http://localhost:3000/api
Click the "Authorize" button (lock icon) at the top
Enter your API_KEY_ACCESS from .env file
Click "Authorize" and "Close"
Now you can test all endpoints directly in the browser

Using curl

curl -H "X-API-Key: your_api_key_access_here" \
  http://localhost:3000/balance?exchange=aster

📡 Unified API Endpoints

All endpoints follow a unified pattern: /{resource}?exchange={exchange_name}

Balance Endpoints

GET /balance?exchange={exchange} - Get account balance and positions
GET /balance/portfolio?exchange={exchange} - Get portfolio summary
GET /balance/positions?exchange={exchange} - Get all open positions
GET /balance/position?exchange={exchange}&symbol={symbol} - Get specific position

Example:

# Get Aster balance
curl -H "X-API-Key: your_key" \
  "http://localhost:3000/balance?exchange=aster"

# Get Hyperliquid positions
curl -H "X-API-Key: your_key" \
  "http://localhost:3000/balance/positions?exchange=hyperliquid"

Market Data Endpoints

GET /market/symbols?exchange={exchange} - Get all tradable symbols
GET /market/ticker?exchange={exchange}&symbol={symbol} - Get 24hr ticker
GET /market/orderbook?exchange={exchange}&symbol={symbol} - Get order book
GET /market/trades?exchange={exchange}&symbol={symbol} - Get recent trades
GET /market/candles?exchange={exchange}&symbol={symbol}&interval={interval} - Get klines/candles
GET /market/funding?exchange={exchange}&symbol={symbol} - Get funding rate history

Example:

# Get BTC ticker from Binance
curl -H "X-API-Key: your_key" \
  "http://localhost:3000/market/ticker?exchange=binance&symbol=BTC-USDT"

# Get ETH orderbook from Hyperliquid
curl -H "X-API-Key: your_key" \
  "http://localhost:3000/market/orderbook?exchange=hyperliquid&symbol=ETH-USD"

Trading Endpoints

POST /trading/order/market - Place market order
POST /trading/order/limit - Place limit order

🔌 Architecture Overview

Unified API Pattern

Instead of separate endpoints per exchange, we use a unified pattern:

Traditional Approach (Bad):
- /aster/balance
- /hyperliquid/balance
- /binance/balance
- /okx/balance
→ 4 exchanges × 50 operations = 200 endpoints!

Unified Approach (Good):
- /balance?exchange=aster
- /balance?exchange=hyperliquid
- /balance?exchange=binance
- /balance?exchange=okx
→ 50 endpoints serving all exchanges

Exchange Factory Pattern

The ExchangeFactory dynamically resolves the correct service based on the exchange parameter:

// Client request
GET /balance?exchange=aster

// Factory resolves
ExchangeFactory → AsterPerpetualBalanceService → Execute

// Client request
GET /balance?exchange=hyperliquid

// Factory resolves
ExchangeFactory → HyperliquidBalanceService → Execute

Interface-Driven Design

All exchange implementations follow standard interfaces:

IBalanceService: Balance and portfolio operations
IMarketDataService: Market data operations
ITradingService: Trading operations

This ensures:

Consistency: All exchanges work the same way
Testability: Easy to mock and test
Maintainability: Changes in one place affect all exchanges
Extensibility: New exchanges just implement interfaces

Symbol Normalization

Each exchange uses different symbol formats:

Aster: BTCUSDT
Hyperliquid: BTC
Binance: BTCUSDT
OKX: BTC-USDT-SWAP

The SymbolNormalizerMiddleware automatically converts symbols:

Client → "BTC-USDT" → Middleware → "BTCUSDT" (Aster)
Client → "BTC-USDT" → Middleware → "BTC" (Hyperliquid)
Client → "BTC-USDT" → Middleware → "BTC-USDT-SWAP" (OKX)

Adding a New Exchange

To add support for a new exchange:

Create exchange module structure:

mkdir -p src/exchanges/newexchange/perpetual/services
mkdir -p src/exchanges/newexchange/shared
mkdir -p src/exchanges/newexchange/types

Implement standard interfaces:

Create services implementing:
- IBalanceService (balance operations)
- IMarketDataService (market data)
- ITradingService (trading operations)
Create API service:

Implement REST API client in shared/newexchange-api.service.ts
Define types:

Add exchange-specific types in types/index.ts
Create configuration:

Add config in src/config/newexchange.config.ts
Register in factory:

Add exchange to ExchangeFactory resolution logic
Update exchange enum:

Add to ExchangeName enum in common/types/exchange.types.ts
Test thoroughly:

Create unit tests for all services

🔒 Security Features

Environment Variables: Sensitive data stored securely in .env
API Key Authentication: All endpoints protected with API key guard
HMAC Signatures: Secure API authentication for supported exchanges
Input Validation: Comprehensive validation using class-validator
Rate Limiting: Built-in protection against API rate limits
Error Sanitization: Sensitive information removed from logs

📊 Monitoring & Logging

The application uses structured logging with contextual information:

Error: System errors and critical failures
Warn: Non-critical issues and warnings
Info: General application information
Debug: Detailed debugging information (set LOG_LEVEL=debug)

Logs include request IDs, exchange names, and operation metadata for easy troubleshooting.

🐛 Troubleshooting

Common Issues

Connection Failed:

Verify API credentials in .env file
Check network connectivity
Ensure exchange API is accessible

Invalid Signature:

Verify API secret is correct
Check system time synchronization
Ensure timestamp is within acceptable range

Rate Limited:

Reduce request frequency
Implement exponential backoff
Check exchange rate limit documentation

Symbol Not Found:

Verify symbol format for the specific exchange
Check if symbol is supported by the exchange
Use /market/symbols endpoint to list available symbols

Debug Mode

Enable detailed logging:

LOG_LEVEL=debug pnpm start:dev

📝 API Response Format

All API responses follow a standardized format:

Success Response:

{
  "success": true,
  "data": {
    // Response data here
  },
  "timestamp": "2024-01-01T00:00:00.000Z"
}

Error Response:
