PumpFun Token Launcher

Launch new tokens on the Pump.fun protocol using the native Pump SDK integrated into SolanaOS.

Prerequisites

• Solana wallet configured (solanaos birth)
• HELIUS_RPC_URL or SOLANA_RPC_URL set in vault
• Sufficient SOL balance for transaction fees (~0.05 SOL)

How It Works

The Pump SDK provides offline instruction builders for token creation. This skill uses the PumpSdk.createV2Instruction() method to build a token creation transaction.

Token Creation Flow

1. Generate a new mint keypair
2. Upload metadata JSON to Arweave/IPFS (name, symbol, image, description)
3. Build the createV2 instruction via PUMP_SDK.createV2Instruction()
4. Optionally build a combined createV2AndBuy to purchase initial supply
5. Sign and send the transaction

Example Usage

import { Keypair, Connection } from "@solana/web3.js";
import { PUMP_SDK, OnlinePumpSdk, getBuyTokenAmountFromSolAmount } from "solanaos";

const connection = new Connection(process.env.HELIUS_RPC_URL!);
const mintKeypair = Keypair.generate();
const creator = wallet.publicKey;

// Create token
const createIx = await PUMP_SDK.createV2Instruction({
  mint: mintKeypair.publicKey,
  name: "My Token",
  symbol: "MYTKN",
  uri: "https://arweave.net/metadata.json",
  creator,
  user: creator,
  mayhemMode: false,
});

// Or create + buy in one transaction
const sdk = new OnlinePumpSdk(connection);
const global = await sdk.fetchGlobal();
const ixs = await PUMP_SDK.createV2AndBuyInstructions({
  global,
  mint: mintKeypair.publicKey,
  name: "My Token",
  symbol: "MYTKN",
  uri: "https://arweave.net/metadata.json",
  creator,
  user: creator,
  amount: new BN(1_000_000_000), // tokens to buy
  solAmount: new BN(100_000_000),  // 0.1 SOL
  mayhemMode: false,
});

Mayhem Mode

Set mayhemMode: true for tokens with randomized bonding curve parameters. This creates unpredictable pricing dynamics.

Safety Notes

• Always test on devnet first — never launch tokens with real funds without testing
• Use mock keypairs for development — never commit real wallet keys
• Token creation is irreversible — once created, the bonding curve is live
