Pump.fun Token Launcher

Launch tokens on pump.fun directly from your agent. Zero middleware fees — direct on-chain via pumpdotfun-sdk. Use when the user wants to create, launch, deploy, or mint a new token or memecoin on pump.fun (Solana). Handles wallet generation, IPFS metadata upload, and on-chain token creation in one command. Supports dry-run mode, encrypted wallet storage, custom images, and optional initial buy. No PumpPortal, no third-party fees. Just provide a name, ticker, description, and image.

Setup

The skill lives at skills/pumpfun-launch/. First run:

bash

cd skills/pumpfun-launch && bun install

Environment

Create .env in the skill folder:

text

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.

bash

cd skills/pumpfun-launch
bun run launch.ts --name "TokenName" --symbol "TKN" --description "My token" --image ./logo.png

⚠️ IMPORTANT — Agent Instructions

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