Pump.fun AI Comment Bot (TypeScript)

This project is a TypeScript CLI automation bot for Pump.fun comments on Solana. It is designed for traders or communities who want to keep token discussions active with AI-assisted comment generation and automated posting.

What This Bot Is For

• Keep a token thread active with regular, varied comments
• Speed up comment creation by generating text with OpenAI
• Run posting from either a fresh generated wallet or an existing wallet
• Maintain a reusable local comment bank in data.json

Core Features

• AI comment generation: Creates comment ideas from a short prompt
• Manual comment input: Add your own custom comments anytime
• Comment library management: Read and reuse saved comments from data.json
• Automated posting loop: Posts comments to a target Pump token mint
• Proxy support: Uses entries in proxy_list.json while posting
• Flexible wallet mode:
  • New temporary wallet mode
  • Existing wallet mode via BOT_KEY in .env

How It Works

1. Start CLI with npm run dev.
2. Choose to generate comments with AI or add comments manually.
3. Comments are stored in data.json.
4. Run the comment bot from:
   • a new generated wallet, or
   • your existing .env wallet (BOT_KEY).
5. Bot logs in, gets token/session data, then posts comments to PUMP_MINT.
6. Bot waits a random interval between posts using COMMENT_MIN_INTERVAL and COMMENT_MAX_INTERVAL.

Benefits For Traders

• Save time: reduce manual writing effort for every post
• Stay active: maintain continuous engagement on token pages
• Simple workflow: menu-based CLI, no complex dashboard needed
• Configurable pace: control post frequency with interval settings
• Reusable content: build your own comment set over time
