SPL-Token Auto Buy & Sell

This automated script facilitates the swapping of targeted SPL-tokens and SOL on Raydium. Users can customize the script's parameters according to their preferences. For testing purposes, the script can be set to simulate swaps by setting executeSwap: false in src/swapConfig.ts.

Requirements

• Node.js
• TypeScript
• Yarn

Usage

1. Environment Setup:

   • Rename the existing .env.example file to .env or create a new .env file.
   • Populate the .env file with your keys:

     RPC_URL=YOUR_RPC_URL
     WALLET_PRIVATE_KEY=YOUR_PRIVATE_KEY

2. Configuration:

   • Open src/swapConfig.ts to adjust the script parameters:

export const swapConfig = {
  executeSwap: true, // Send tx when true, simulate tx when false

  useVersionedTransaction: true, // wether you want to user versioned transaction or legacy transaction

  tokenAAddress: "So11111111111111111111111111111111111111112", // Token to swap for the other, SOL in this case

  maxLamports: 2000000, // Micro lamports for priority fee

  direction: "in" as "in" | "out", // Swap direction: 'in' or 'out'

  liquidityFile: "https://api.raydium.io/v2/sdk/liquidity/mainnet.json",

  OwnerAddress: "", // Your wallet PublicKey

  exitTarget: 1, // Exit target in percentage (e.g. +1%)

  maxRetries: 20,

  intervalMs: 4000, // Interval between every swap

  retryCount: 3, // Retry if the transaction fails.
};

3. Installing Packages:
