pumpdotfun-repumped-sdk

High-level TypeScript SDK for Pump Fun Fixed and reworked https://github.com/rckprtr/pumpdotfun-sdk. Fixed buy, sell and create functions. Also added support for new events. Added jito support for bundle sending. Works on devnet (demo below) and mainnet-beta.
Bundled via Rollup – ESM & CJS builds in dist/.

✨ Features

Module	Highlights
`PumpFunSDK`	one-liner entry point, injects Anchor `Program` & `Connection`
`TradeModule`	`createAndBuy`, `buy`, `sell`, tx builders, slippage helpers
`TokenModule`	metadata upload (IPFS helper), ATA creation, mint helpers
`PdaModule`	utility PDAs: global, event-authority, bonding-curve, metadata, etc.
`EventModule`	typed event listeners with automatic deserialization
`JitoModule`	typed jito bundle submission for buys and sells, to use add jitourl and authkeypair to options when creation sdk instance
IDL exports	`IDL` JSON and `type PumpFun` helper

🔨 Quick Start

  Connection,
  Keypair,
  LAMPORTS_PER_SOL,
  PublicKey,
} from "@solana/web3.js";
import { AnchorProvider, Wallet } from "@coral-xyz/anchor";

const PRIORITY_FEE = { unitLimit: 250_000, unitPrice: 250_000 };

const secret = JSON.parse(process.env.WALLET!); // `[...,64]`
const wallet = Keypair.fromSecretKey(Uint8Array.from(secret));

async function printSOL(conn: Connection, pk: PublicKey, label = "") {
  const sol = (await conn.getBalance(pk)) / LAMPORTS_PER_SOL;
  console.log(`${label} SOL:`, sol.toFixed(4));
}

  });
  const sdk = new PumpFunSDK(provider);
  const mint = Keypair.generate(); // fresh token mint

  await printSOL(connection, wallet.publicKey, "user");

  /* 1️⃣  create + first buy */
  const img = await import("node:fs/promises").then((fs) =>
    fs.readFile("example/images/test.png")
  );

    PRIORITY_FEE
  );
  console.log(
    "pump.fun link →",
    `https://pump.fun/${mint.publicKey}?cluster=devnet`
  );

  /* 2️⃣  second buy */
  await sdk.trade.buy(

    mint.publicKey,
    0.0002 * LAMPORTS_PER_SOL,
    SLIPPAGE_BPS,

  );
  const bal = await getSPLBalance(connection, mint.publicKey, wallet.publicKey);
  console.log("Token balance:", bal / 10 ** DEFAULT_DECIMALS);

  /* 3️⃣  sell all */
  await sdk.trade.sell(

    mint.publicKey,
    BigInt(bal),

  );

}

main().catch(console.error);

Switch DEVNET_RPC to a mainnet endpoint and pass the mainnet program ID to PumpFunSDK if you want to run live.
