Overview

The PumpDotFunSDK is designed to interact with the Pump.fun decentralized application. It provides methods for creating, buying, and selling tokens using the Solana blockchain. The SDK handles the necessary transactions and interactions with the Pump.fun program.

Installation

npm i @jwenlee/pumpdotfun-sdk

Reference

const mint = Keypair.generate();
console.log("Generated address:", mint.publicKey.toBase58());

const provider = getProvider();
const sdk = new PumpFunSDK(provider);

const imageResponse = await fetch(imageUrl);
// console.log("imageResponse", imageResponse);

const arrayBuffer = await imageResponse.arrayBuffer();
const imageFile = new File([Buffer.from(arrayBuffer)], "token-image.jpg", {
  type: "image/jpeg"
});
console.log("imageFile", imageFile);

const tokenMetadata: CreateTokenMetadata = {
  name,
  symbol: ticket,
  description,
  file: imageFile,
  ...optionalParams
};
const metadata = await sdk.createTokenMetadata(tokenMetadata);
console.log("metadata", metadata);

let createTx = await sdk.getCreateInstructions(
  creatorAddress,
  String(tokenMetadata.name),
  String(tokenMetadata.symbol),
  metadata.metadataUri,
  mint
);

// console.log("createTx", createTx);
let tx = new Transaction();
tx.add(createTx);

if (buyAmountSol > 0) {
  const globalAccount = await sdk.getGlobalAccount("finalized");
  const buyAmount = globalAccount.getInitialBuyPrice(buyAmountSol);
  const buyAmountWithSlippage = calculateWithSlippageBuy(
    buyAmountSol,
    slippageBasisPoints
  );
  // @ts-ignore
  const buyTx = await sdk.getBuyInstructions(
    creatorAddress,
    mint.publicKey,
    globalAccount.feeRecipient,
    buyAmount,
    buyAmountWithSlippage,
    "confirmed",
    true,
    creatorAddress
  );
  tx.add(buyTx);
