Im using @solana/spl-token to mint a legacy token on Solana (not token2022).
The problem is that I cannot set any updateAuthority for it so I cannot set/update its metadata with Metaplex after minting.
Below is how I'm minting the token:
import { createMint, getOrCreateAssociatedTokenAccount, mintTo, setAuthority } from '@solana/spl-token';import { clusterApiUrl, Connection, Keypair, LAMPORTS_PER_SOL } from '@solana/web3.js';import { getKeypairFromFile } from "@solana-developers/helpers";const connection = new Connection( clusterApiUrl('devnet'),'confirmed' );export async function createAndMint( supply: number, decimals: number = 9) {const payer = await getKeypairFromFile("keypair.json");const mintAuthority = payer;const freezeAuthority = null;const mint = await createMint( connection, payer, mintAuthority.publicKey, freezeAuthority, decimals );console.log("Mint: ",mint.toBase58());const tokenAccount = await getOrCreateAssociatedTokenAccount( connection, payer, mint, payer.publicKey )console.log("Token Account: ", tokenAccount.address.toBase58());await mintTo( connection, payer, mint, tokenAccount.address, mintAuthority, supply * (10 ** decimals), ).then((tx) => { console.log("Minted: ", supply, " tokens to ", tokenAccount.address.toBase58()); console.log("Signature: ", tx); }); return mint;}example of a minted token: https://solscan.io/token/F87BX1QSwXJsjFsUNMY8rConRa8eaAusFu2xmEKcQkzF?cluster=devnet
as you can see in the Authority section, there is no update Authority set for it (null).so I cannot set metadata with Metaplex for it.
But when I use spl-token CLI to create the token, updateAuthority is set to the same publicKey as mint's.
could anyone please help me do it inside a JS module and not through the CLI?
