Launch a token on pump.fun with your custom contract address.

This repository contains a bot for automated token creation on the Solana blockchain on Pump.fun. The bot interacts with the PumpPortal API to create and manage tokens automatically.

You can view the example.png file in the repository to see the log of a token being created.

Make sure to have a "logo.png" file in the project directory to use as Token Image.

• Automated Token Creation:
  • Uploads metadata to IPFS.
  • Creates new tokens using the Pump.fun API.
  • Handles transaction signing and submission.
  • Allows using a predefined mint address if provided, or generates a new one dynamically.
• Secure Key Management:
  • Uses environment variables to store only constant values (RPC endpoint and deployer private key).
  • Accepts token-related parameters as function arguments for flexibility and integration.

• Solana Web3.js – For blockchain interactions.
• PumpPortal API – For token management.
• Node.js – Backend environment.
• dotenv – For environment variable management.
• bs58 – For key decoding.
• fs/promises – For file handling.
• FormData API – For metadata submission.

1. Clone the repository:

   git clone https://github.com/Malakia-sol/pumpfun-launcher
   cd pumpfun-launcher

2. Install dependencies:

   npm install

3. Create a .env file and provide the following environment variables:

   RPC_ENDPOINT=your_rpc_endpoint
   DEPLOYER_PRIVATE_KEY=deployer_private_keys
   CUSTOM_CA_PRIVATE_KEY= // leave blank if you dont use a custom ca

4. Run the bot with custom token parameters:

   node launcher.js

• The bot will use the .env file only for constant values like the RPC endpoint and deployer private key.
• Token-specific parameters must be passed as arguments e.g.:

  // Configurable token parameters
     const tokenConfig = {
         name: "MyToken", // Token name
         symbol: "MTK", // Symbol
         description: "This is a test token", // Description
         twitter: "https://x.com/example", // Twitter link
         telegram: "https://t.me/example", // Telegram link
         website: "https://example.com", // Website
         showName: "true", // Don't touch this!
         amount: 0.0001, // SOL amount to buy at creation
         slippage: 0.5, // Slippage
         priorityFee: 0.0005, // Priority Fee
         pool: "pump", // Always "pump"
     };

• If a mint private key is provided, it will be used; otherwise, the bot will generate a new one.
• Monitor the output logs for transaction status and confirmations.

• Ensure private keys are kept secure and never shared.
• Monitor network fees and adjust priorityFee accordingly for better execution.
