Multithreaded Copy Trading Bot <> Solana

This repository implements a multithreaded copy trading bot that monitors and replicates trading actions across different accounts on Solana. It is designed for efficiency and reliability, leveraging custom WebSocket listeners and multithreading to ensure optimal performance.

---

Features

• Multithreaded Execution: Tracks multiple account sets on different threads for high performance.
• Reliable WebSocket Listener: Implements a custom wssListener with enhanced stability.
• GRPC Support: Includes grpcListener as an alternative to WebSocket for tracking accounts.
• Supported DEXs:
  • RaydiumV4
• Dynamic Configuration: Easily customize accounts, and other parameters via configuration files.

---

Requirements

• Node.js (v14 or higher)
• npm or yarn
• Access to:
  • Solana RPC Node
  • Yellowstone GRPC

---

Installation

1. Clone the repository:

2. Install dependencies:

   npm install

   Or, if you're using Yarn:

   yarn install

3. Configure environment variables:

   • Copy the .env.example file to .env.
   • Fill in your configuration details (e.g., API keys, RPC URLs, and thresholds).

4. Modify config.json to set accounts, and other parameters as required

5. Toggle between grpcListener/wssListener by commenting/uncommenting listener init lines currently at 207/208 in index.js

6. This was developed using AllThatNode's free gRPC service, which behaves unpredictably by stopping message streams after 1 minute, even though the connection remains active. To address this, a resubscription routine has been implemented. Important: If you're using a reliable gRPC service, this workaround might cause issues like exceeding maximum subscription limits. Recommendation: Test the behavior with and without the resubscription logic by commenting out the corresponding lines in the code to ensure compatibility with your setup. Lines: 184 listener.js

Usage

Starting the Bot

To start the bot, use:

npm start

Or with Yarn:

yarn start

---

Architecture

• Listeners:
  • wssListener: Reliable WebSocket-based listener with custom socket limits.
  • grpcListener: GRPC-based listener for accounts on Solana.
• Multithreading:
  • Each thread independently monitors a set of wallets.
  • Trades are created, simulated and then can be executed based on monitoring
• Error Handling:
  • Gracefully handles network issues, transaction failures, and insufficient funds.
  • Trade values are in the smallest unit(decimals).

---

Common Issues

• Insufficient Funds for Fees: Ensure executing wallet has enough SOL for transaction fees.

• WebSocket Instability: Use the grpcListener as an alternative if WebSocket connections are unreliable.

• Redis Errors: Ensure Redis is running and correctly configured.
