Best tool for holdling your token on moment of token launching
This bundler is designed for user to be first buyer This bot runs mint token tx + create pool tx + add liquidity tx + first buyer tx in one bundled tx
In Pumpfun , there are many sniping bots which buy token as soon as token launched. That makes user not able to hold majority of his token for maintaining specific token price safely. In other words , that means that token is not launchers token and token launcher lost his token and other fees on launching token In this case , we can use bundler As for the bundler , It can helps spam launch in first buy on Pumpfun
First buyer is the term which means user who buy token as soon as token launched In tokenomics , the moment of the lowest token price is as soon as token launched So , if token launcher hold his token on that moment , he can own this token on moment of the lowest token price
In terms of aspect of bundling , there are many things which take effect in bundling But the most important thing in bundling is wallet count which buys token with in the moment of token launching
Bot of this repo proceeds bundle buy with 2 wallets. Of cause , we can proceed bundle with custom wallet count within 16 wallets It's paid project Contact me if you need that bundling project
| Aspect | Free | Paid |
|---|---|---|
| Bundle Wallet Count | 2 | 16 (Max) |
npm i pumpdotfun-sdk
First you need to create a .env file and set your RPC URL like in the .env.example
Then you need to fund an account with atleast 0.004 SOL that is generated when running the command below
npx ts-node example/basic/index.ts
import dotenv from "dotenv";
import { Connection, Keypair, LAMPORTS_PER_SOL } from "@solana/web3.js";
import { DEFAULT_DECIMALS, PumpFunSDK } from "pumpdotfun-sdk";

import { AnchorProvider } from "@coral-xyz/anchor";
import {
getOrCreateKeypair,
getSPLBalance,
printSOLBalance,
printSPLBalance,
} from "./util";
const getProvider = () => {
};
const createAndBuyToken = async (sdk, testAccount, mint) => {
};
const buyTokens = async (sdk, testAccount, mint) => {
};
const sellTokens = async (sdk, testAccount, mint) => {
};
const main = async () => {
try {
const provider = getProvider();
const sdk = new PumpFunSDK(provider);
const connection = provider.connection;
const testAccount = getOrCreateKeypair(KEYS_FOLDER, "test-account");
const mint = getOrCreateKeypair(KEYS_FOLDER, "mint");
await printSOLBalance(connection, testAccount.publicKey, "Test Account keypair");
const globalAccount = await sdk.getGlobalAccount();
console.log(globalAccount);
const currentSolBalance = await connection.getBalance(testAccount.publicKey);
if (currentSolBalance === 0) {
console.log("Please send some SOL to the test-account:", testAccount.publicKey.toBase58());
return;
}
console.log(await sdk.getGlobalAccount());
let bondingCurveAccount = await sdk.getBondingCurveAccount(mint.publicKey);
if (!bondingCurveAccount) {
await createAndBuyToken(sdk, testAccount, mint);
bondingCurveAccount = await sdk.getBondingCurveAccount(mint.publicKey);
}
if (bondingCurveAccount) {
await buyTokens(sdk, testAccount, mint);
await sellTokens(sdk, testAccount, mint);
}
} catch (error) {
console.error("An error occurred:", error);
}
};
main();The PumpDotFunSDK class provides methods to interact with the PumpFun protocol. Below are the method signatures and their descriptions.

TransactionResult.
addEventListener<T extends PumpFunEventType>(
eventType: T,
callback: (event: PumpFunEventHandlers[T], slot: number, signature: string) => void
): number- Adds an event listener for the specified event type.
- Parameters:
eventType: The type of event to listen for.callback: The callback function to execute when the event occurs.
- Returns: An identifier for the event listener.
removeEventListener(eventId: number): void- Removes the event listener with the specified identifier.
- Parameters:
eventId: The identifier of the event listener to remove.
To run the basic example for creating, buying, and selling tokens, use the following command:
npx ts-node example/basic/index.tsThis example demonstrates how to set up event subscriptions using the PumpFun SDK.
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);
});
console.log("Subscribed to createEvent with ID:", createEventId);
const tradeEventId = sdk.addEventListener("tradeEvent", (event, slot, signature) => {
console.log("tradeEvent", event, slot, signature);
});
console.log("Subscribed to tradeEvent with ID:", tradeEventId);
const completeEventId = sdk.addEventListener("completeEvent", (event, slot, signature) => {
console.log("completeEvent", event, slot, signature);
});

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