This project is a Solana Market Maker Bot designed to automate trading strategies on the Solana blockchain using the Jupiter swap protocol. It aims to maintain a balanced portfolio across specified token pairs by executing trades based on predefined strategies and market conditions.

The project is structured as follows:

• Node.js (version 18.x or later)
• A funded Solana wallet

1. Install Node.js: Ensure that you have Node.js (version 14.x or later) installed on your machine. You can download it from here
2. Clone the Repository: Clone the repository to your local machine using the following command:

   git clone https://github.com/gianlucamazza/solana-mmaker.git
   cd solana-market-maker-bot

3. Install Dependencies: Install the necessary Node.js dependencies by running:

   npm install

4. Environment Variables: Set up your environment variables by creating a .env file in the project root with the following content:

   SOLANA_RPC_ENDPOINT=<Your Solana RPC endpoint URL>
   USER_KEYPAIR=<Path to your Solana wallet keypair file>
   ENABLE_TRADING=<true or false>
   

   Replace <Your Solana RPC endpoint URL> with your Solana RPC endpoint, <Path to your Solana wallet keypair file> with the path to your Solana wallet keypair file, and set ENABLE_TRADING to true to enable live trading or false to run in simulation mode.

To start the market maker bot, execute the following command in the terminal:

npm start

This will initiate the market-making strategy defined in src/strategies/basicMM.ts, using the Jupiter protocol for swap transactions.

The market-making strategy can be customized in src/strategies/basicMM.ts. You can define which token pairs to trade, set tolerance levels, rebalance percentages, and more within this file.

• Always review the code and understand the strategy before enabling live trading.
• Start with small amounts to test the bot's performance and behavior.
• Keep your Solana wallet keypair file secure and never share it with anyone.
