Integration Examples
Use the SPL Memo IDL in your application with these code examples for TypeScript, Rust, and Python.
import { Connection, PublicKey } from "@solana/web3.js";
import { Program, AnchorProvider, Idl } from "@coral-xyz/anchor";
// Load the SPL Memo IDL
import idl from "./spl memo.json";
const PROGRAM_ID = new PublicKey("MemoSq4gqABAXKb96qnH8TysNcWxMyWCqXgDLGmfcHr");
// 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.sPL_Memo
.fetch(accountPublicKey);
console.log("Account data:", accountData);
// Build and send an instruction
const tx = await program.methods
.initialize(/* ...args */)
.accounts({
/* ...required accounts */
})
.rpc();

This IDL contains 0 instructions, 0 account types, 0 events, and 0 type definitions.
How do I use the SPL Memo IDL in my project?
Download the JSON file and import it in your project. With TypeScript, use the @coral-xyz/anchor package to create a Program instance. In Rust, use anchor-client. For Python, use anchorpy. See the integration examples above for complete code snippets in all three languages.
