What is pumpfun-bundler-bot?

This repository is a toolkit for coordinating token launches on two Solana-based platforms: pump.fun and bonk.fun, which are meme coin launchpad services on the Solana blockchain. The core technique is called bundling, grouping multiple transactions together so they all execute in a single block on the blockchain, appearing atomic (all or nothing) to outside observers. The tool automates the process of creating a new token and simultaneously having multiple wallets buy it in the same block. It distributes SOL (Solana's native currency) from a main wallet to several sub-wallets, creates the token with metadata and an image, generates an Address Lookup Table (a Solana optimization that compresses many wallet addresses into a smaller reference to reduce transaction fees), and then submits the whole package as a bundle. The bundle submission goes through Jito or Lil Jito, which are services that help guarantee all transactions in a bundle land in the same block, providing a form of protection against other traders front-running the launch. You would use this if you are launching a token on pump.fun or bonk.fun and want to coordinate an initial buy across multiple wallets in a single coordinated action at launch time. The repository is split into two subfolders, one for each platform, and is built with TypeScript running on Node.js. It requires a funded Solana wallet and access to a Solana RPC endpoint.
