Use it in your code

Load the DumpFun 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 DumpFun IDL
import idl from "./dumpfun.json";

const PROGRAM_ID = new PublicKey("DumpFunGAgW6kPHzWMA3Nnqecyrd6SGnLZvNGp2aHwEa");

// 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.dumpFun
  .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);

Frequently asked questions

What is the DumpFun IDL?

The DumpFun IDL (Interface Definition Language) is a JSON schema that describes the on-chain program interface for the DumpFun smart contract on Solana. It defines all available instructions, account structures, events, and types needed to interact with the program. This one has 5 instructions, 1 account types, 4 events and 6 type definitions.

How do I use the DumpFun IDL in my project?

You can use the DumpFun IDL with Anchor framework clients in TypeScript (@coral-xyz/anchor), Rust (anchor-client), or Python (anchorpy). Download the JSON file, import it in your project, and use it to create a Program instance that can call instructions and decode accounts.

What is the DumpFun program address on Solana?

The DumpFun program is deployed at address DumpFunGAgW6kPHzWMA3Nnqecyrd6SGnLZvNGp2aHwEa on Solana mainnet.

What version of the DumpFun IDL is this?

This is version 0.1.0 of the DumpFun IDL. IDL versions follow program deployments and change as the protocol evolves, so check it against the program on-chain before you integrate.

Build on DumpFun with AllenHark

Stream the program's accounts and transactions with Yellowstone gRPC, read its state over Solana RPC, or see its transactions before the block is built with ShredStream. To trade against it, try the trading bots or the PumpFun sniper.
