Setup

Prerequisites

• Node.js >= 18.0.0
• npm or yarn
• Geyser API access
• Solana RPC endpoint
• MongoDB (optional, for data persistence)

Installation

1. Clone the repository:

git clone <repository-url>
cd 0x-raydium-migration-sniper

2. Install dependencies:

npm install

3. Configure environment variables:

cp .env.example .env

Edit .env with your configuration:

• GEYSER_RPC: Your Geyser RPC endpoint
• GEYSER_KEY: Your Geyser API key
• RPC_URL: Your Solana RPC endpoint
• ADMIN_PRIVATE_KEY: Your wallet private key (base58 encoded)
• CLUSTER: Network (mainnet or devnet)
• DB_URL: MongoDB connection string (optional)

Build

npm run build

Development

npm run dev

Production

npm start

Configuration

Environment Variables

Variable	Required	Description
GEYSER_RPC	Yes	Geyser RPC endpoint
GEYSER_KEY	Yes	Geyser API key
RPC_URL	Yes	Solana RPC endpoint
ADMIN_PRIVATE_KEY	Yes	Wallet private key (base58)
CLUSTER	No	Network (mainnet or devnet)
DB_URL	No	MongoDB connection string
TICKERS	No	Comma-separated list of tickers to monitor
SLIPPAGE	No	Slippage tolerance (default: 0.001)
LOG_LEVEL	No	Logging level (debug, info, warn, error)

Usage

The bot automatically starts monitoring for migration transactions when launched. When a migration is detected:

1. The bot logs the migration details
2. Creates necessary token accounts
3. Executes a swap on the Raydium CPMM pool
4. Logs the transaction result

Scripts

• npm run dev - Start development server with hot-reload
• npm run build - Build the TypeScript project
• npm run build:watch - Build with watch mode
• npm start - Start production server
• npm run type-check - Run TypeScript type checking
• npm run clean - Clean build directory

Architecture

Core Components

• Config Manager: Centralized configuration with validation
• Logger: Structured logging with different levels
• Error Handler: Custom error classes and handling
• Database: MongoDB connection management

Handlers

• Geyser Handler: Manages Geyser stream subscription and reconnection
• Migration Handler: Detects migrations and executes trades

Services

• Raydium CPMM: Integration with Raydium CPMM swap functionality
• Jito: Transaction execution via Jito bundles

Error Handling

The project uses custom error classes for better error handling:

• AppError: Base error class
• ConfigurationError: Configuration-related errors
• NetworkError: Network-related errors
• TransactionError: Transaction execution errors
• ValidationError: Validation errors

Logging

The logger supports different log levels:

• debug: Detailed debugging information
• info: General information
• warn: Warning messages
• error: Error messages with stack traces

Set the log level via LOG_LEVEL environment variable.

Security

• Never commit .env file
• Store private keys securely
• Use environment variables for sensitive data
• Validate all configuration on startup
