Notice: This project was inspired by https://github.com/Allen-Taylor/pump_fun_py and modified for use in typescript with some extra additions. Also modified the code to send the associated token account creation in a single transaction with the buy or sell for increased speed.

Solana Pump Fun is an open-source package designed to facilitate the execution and simulation of buy and sell transactions for pump.fun on the Solana blockchain. This tool is useful for developers and enthusiasts looking to understand transaction mechanics and resource consumption on Solana.

• Simulates buy and sell transactions for pump.fun on the Solana blockchain.
• Executes buy and sell transactions for pump.fun on the Solana blockchain.
• Provides detailed logs of transaction steps and resource consumption.
• Easy to use and integrate into existing projects.

Ensure you have the following installed:

• Node.js (version 14 or later)
• npm
• TypeScript

To install the package, clone the repository and install the dependencies:

git clone https://github.com/bilix-software/solana-pump-fun.git
cd solana-pump-fun
npm install

Before running the simulation, you need to set up your private key and specify the token mint. Open the example.ts file and replace the placeholder values with your actual private key and token mint address.

In example.ts, set your private key, token mint address, and transaction mode:

const privateKey = 'your_private_key'; // Replace with your actual private key
const mintAddress = 'your_token_mint_address'; // Replace with actual token mint address
const txMode = TransactionMode.Simulation; // Set to Simulation to test, Execution to perform

To run the example simulation scripts, use Node.js to execute the example.js file or compile and run the example.ts file. This will simulate buy and sell transactions and output detailed logs.

1. Ensure your example.ts file is correctly configured.
2. Compile the TypeScript files:

npx tsc

3. Run the compiled JavaScript file:

node example.js

If you prefer to run the transactions in simulation mode (without actual transactions on the blockchain), ensure the txMode is set to TransactionMode.Simulation. This mode will help you understand the transaction process without incurring any cost.

Below is an example of the output generated when running the simulation:

• src/: Contains the source code for the package.
• example.js: Example script to demonstrate how to use the package.
• example.ts: TypeScript version of the example script.
• package.json: Project metadata and dependencies.
• tsconfig.json: TypeScript configuration file.
