alchemz/solana-pumpfun-token-bundler

This is a TypeScript command-line tool for orchestrating token launches on pump.fun, a Solana-based platform where anyone can create and launch a new cryptocurrency token. The tool specifically addresses a practice called "bundling", coordinating multiple wallets to buy a newly created token in the same transaction bundle as its creation, giving the appearance of immediate demand. The workflow starts by uploading token metadata (name, symbol, description, image, and social links) to pump.fun's IPFS-based metadata storage. It then creates the token on-chain and simultaneously submits buy transactions from multiple "bundler" wallets in a single Jito bundle, a Solana mechanism for submitting a group of transactions that land in the same block. An address lookup table (a Solana optimization that lets a transaction reference many wallet addresses without exceeding size limits) is built on the fly to fit all the bundler buys. After launch, the tool provides menu options to sell and rebuy across bundler wallets, sweep SOL back from those wallets, and check balances. The README includes a security and compliance note explicitly warning that coordinated trading and misleading launches may violate law or Pump.fun's terms of service. This tool is primarily used by people launching meme tokens who want to seed their own initial trading activity. It requires Node.js 18 or newer, a paid Solana RPC endpoint, and dedicated wallets that should never hold significant funds.
