Use it in your code

Load the Pump.fun IDL with Anchor in TypeScript, Rust or Python.

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

// Load the Pump.fun IDL
import idl from "./pump.fun.json";

const PROGRAM_ID = new PublicKey("6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P");

// Set up the provider and program
const connection = new Connection("https://api.mainnet-beta.solana.com");
const provider = new AnchorProvider(connection, wallet, {
  commitment: "confirmed",
});
const program = new Program(idl as Idl, provider);

// Fetch and decode an account
const accountData = await program.account.pump_fun
  .fetch(accountPublicKey);
console.log("Account data:", accountData);

// Build and send an instruction
const tx = await program.methods
  .initialize(/* ...args */)
  .accounts({
    /* ...required accounts */
  })
  .rpc();
console.log("Transaction signature:", tx);
