import { Connection, PublicKey } from "@solana/web3.js";
import { Program, AnchorProvider, Idl } from "@coral-xyz/anchor";
// Load the Token-2022 IDL
import idl from "./token-2022.json";

// 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.token_2022
.fetch(accountPublicKey);
console.log("Account data:", accountData);
// Build and send an instruction
