Launch tokens on Pump.fun with coordinated Jito bundles. Create, fund bundler wallets, execute simultaneous buys, and manage SOL distribution — all from an interactive CLI built for Solana token launches.

On Pump.fun, the first blocks after launch often determine who holds supply. A bundler lets you:

1. Create a token with metadata uploaded to Pump.fun IPFS
2. Fund multiple bundler wallets in one batch
3. Buy simultaneously via Jito bundles — all txs land in the same block
4. Manage holder wallets — distribute SOL, gather proceeds, sell positions

This repo is the full toolkit: presimulation, ALT (Address Lookup Table) setup, LilJito execution, and an interactive menu for every step.

• Node.js LTS
• Solana wallets with SOL (creator + bundler provider)
• Fast RPC (HTTPS + WSS)
• Jito block engine access

The interactive CLI walks you through:

• Token creation and metadata setup
• Presimulation and validation
• Bundler wallet funding
• Coordinated Jito buy bundles
• SOL distribution and gathering
• Position selling workflows

Select options by number — no complex flag combinations required.

• Dedicated hot wallets — never use your main holdings wallet
• Authenticated RPC — public endpoints leak txs to mempool snipers
• Review npm audit — transitive Anchor/Raydium deps may have advisories
• Keep settings.ts gitignored — it holds private keys
• Test on devnet before mainnet launches (where supported)

Token launches involve regulatory, financial, and technical risk. Bundled buys may be subject to platform rules and local laws. This software is provided as-is for developers who understand Solana and Pump.fun mechanics. Authors not liable for losses, failed bundles, or account restrictions.
