Pump.fun Token Launcher
Setup
The skill lives at skills/pumpfun-launch/. First run:
cd skills/pumpfun-launch && bun install
Environment
Create .env in the skill folder:
HELIUS_RPC_URL=https://mainnet.helius-rpc.com/?api-key=YOUR_KEY
WALLET_PRIVATE_KEY=base58_encoded_private_key
Get a free Helius key at https://dev.helius.xyz/
If WALLET_PRIVATE_KEY is not set, the script will generate a new wallet and save it to .wallet.key (encrypted with a password prompt). Fund the wallet with SOL before launching.

⚠️ IMPORTANT — Agent Instructions
- ALWAYS confirm with the user before running the launch command. Show them the token name, symbol, description, image, and buy amount.
- ALWAYS use
--dry-runfirst to validate parameters before real launch. - Warn the user that this creates a REAL token on Solana mainnet and costs real SOL.
- Launching costs ~0.02 SOL (rent + fees). Initial buy is additional.
- On success, report the mint address and transaction signature to the user.
- The pump.fun link will be:
https://pump.fun/<MINT_ADDRESS>
