How to Get a Token Mint
In order to get the current supply, authority, or decimals a token has, you will need to get the account info for the token mint.
import { clusterApiUrl, Connection, PublicKey } from "@solana/web3.js";
import { getMint } from "@solana/spl-token";
(async () => {
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
const mintAccountPublicKey = new PublicKey(
"8mAKLjGGmjKTnmcXeyr3pr7iX13xXVjJJiL6RujDbSPV",
);
let mintAccount = await getMint(connection, mintAccountPublicKey);
console.log(mintAccount);
/*
