This is a command-line tool for launching and trading tokens on Pump.fun, a Solana blockchain platform where anyone can create and immediately trade a new cryptocurrency token. The tool coordinates multiple wallets to buy a newly created token within the same block it is launched, a technique called bundling. It submits these coordinated transactions through Jito, a service that allows grouping multiple transactions for inclusion together in a single block. The CLI has a menu with four main operations. The first creates a new token on Pump.fun by uploading metadata and an image, then simultaneously executes buy orders from multiple bundler wallets in the same transaction bundle. The second handles sell and rebuy flows for an existing token. The third sweeps SOL out of the bundler wallets or distributes SOL into them in batches. The fourth shows current balances across all wallets. Setup requires Node.js 18 or newer. You configure the tool through a settings file where you provide the wallet private keys for the token creator account and the bundler wallets, along with the token metadata such as name, symbol, description, and a path to an image file. RPC endpoint URLs and Jito configuration are set in a separate environment file. The README warns that the settings file should never be committed to version control since it contains private keys. The tool's repository description mentions bypassing on-chain wallet distribution analysis tools, and the security section of the README notes that coordinated trading, misleading launches, or market manipulation may violate applicable law or the terms of Pump.fun and RPC providers. The README states the user is responsible for compliant use. The license is ISC.
