🚀 Pumpfun Bundler SDK

Overview

Pumpfun Bundler SDK is the fastest and most efficient self-bundling script for Pump.fun, enabling you to create a token and simulate market activity by purchasing it with 25 wallet addresses in a single bundle. Perfect for creators aiming to streamline token deployment and bootstrapped buying activity.

---

🛠 Installation

npm install pumpdotfun-sdk

---

⚙️ Usage Example

Step 1: Configure Environment

Create a .env file based on .env.example, and set your RPC URL:

HELIUS_RPC_URL=https://your-rpc-endpoint

Step 2: Fund Wallet

The script generates a new keypair. Ensure it has at least 0.004 SOL to cover network fees.

Step 3: Customize Token Metadata

Edit the following metadata before running the script:

const metadata = {
  name: "Bolt token",
  symbol: "Bolt",
  description: "Brave Veer & Bolt",
  image: "./upload/img.jpg",
  showName: true,
  createdOn: "https://pump.fun",
  twitter: "https://x.com/pepa_inu",
  telegram: "https://t.me/pepaonsols",
  website: "https://www.pepa-inu.com"
};

Step 4: Run the Script

📡 Event Subscription Example

Monitor createEvent, tradeEvent, and completeEvent from the blockchain.

File: example/events/events.ts

import dotenv from "dotenv";
import { Connection, Keypair } from "@solana/web3.js";
import { PumpFunSDK } from "pumpdotfun-sdk";
import NodeWallet from "@coral-xyz/anchor/dist/cjs/nodewallet";
import { AnchorProvider } from "@coral-xyz/anchor";

dotenv.config();

const getProvider = () => {
  if (!process.env.HELIUS_RPC_URL) {
    throw new Error("Please set HELIUS_RPC_URL in .env file");
  }

  const connection = new Connection(process.env.HELIUS_RPC_URL);
  const wallet = new NodeWallet(new Keypair());
  return new AnchorProvider(connection, wallet, { commitment: "finalized" });
};

const setupEventListeners = async (sdk) => {
  const createEventId = sdk.addEventListener("createEvent", (event, slot, signature) => {
    console.log("createEvent", event, slot, signature);
  });

  const tradeEventId = sdk.addEventListener("tradeEvent", (event, slot, signature) => {
    console.log("tradeEvent", event, slot, signature);
  });

  const completeEventId = sdk.addEventListener("completeEvent", (event, slot, signature) => {
    console.log("completeEvent", event, slot, signature);
  });

  console.log("Subscribed to events:", { createEventId, tradeEventId, completeEventId });
};

const main = async () => {
  try {
    const provider = getProvider();
    const sdk = new PumpFunSDK(provider);
    await setupEventListeners(sdk);
  } catch (error) {
    console.error("An error occurred:", error);
  }
};

main();
