open-builders/pumpfun-bundler-pump.fun-bundler-solana-token-bundler-bot

This is a TypeScript tool for launching tokens on pump.fun, a platform built on the Solana blockchain where people create and trade meme coins. The specific problem this tool solves is coordination: when you create a new token, you often want multiple wallets to buy it at the exact same moment the token goes live, rather than buying one at a time. Doing those buys simultaneously is called "bundling", and it requires special infrastructure on Solana. The tool handles the full sequence automatically. It creates the token, uploads its metadata (name, description, image), distributes Solana's currency (SOL) from a main wallet into several child wallets, then fires coordinated buy instructions from all of those wallets in a single batch. On the real Solana network (called mainnet), those batches go through Jito or Lil-Jit, which are services that process groups of transactions together. On the test network (devnet), it falls back to a simpler step-by-step approach without those services. Configuration happens through a single .env file. You set things like how many wallets to use, how much SOL each one spends, which network to run on, and your wallet's private key. There is also an optional vanity mode that generates a token address ending in the letters "pump". The README includes a detailed table of every setting and what it does. After the launch, utility scripts let you check status, gather SOL back from the child wallets, and clean up the Address Lookup Tables that Solana uses to compress transaction data. These cleanup steps matter because unused on-chain accounts can tie up small amounts of SOL indefinitely. The README includes a disclaimer that this is for educational and research use, and that you are responsible for complying with platform rules, tax obligations, and the safety of your own private keys. It also warns to never commit your .env file or generated key files to version control. The license is ISC.
