How to Get All Token Accounts by Authority

You can fetch token accounts by owner. There are two ways to do it.

Get All Token Account

import { TOKEN_PROGRAM_ADDRESS } from "@solana-program/token";
import { address, createSolanaRpc } from "@solana/kit";

const rpc_url = "https://api.devnet.solana.com";
const rpc = createSolanaRpc(rpc_url);

let owner = address("4kg8oh3jdNtn7j2wcS7TrUua31AgbLzDVkBZgTAe44aF");

let response = await rpc
	.getTokenAccountsByOwner(
		owner,
		{ programId: TOKEN_PROGRAM_ADDRESS },
		{ encoding: "jsonParsed" }
	)
	.send();

response.value.forEach((accountInfo) => {
	console.log(`pubkey: ${accountInfo.pubkey}`);
	console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
	console.log(
		`owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`
	);
	console.log(
		`decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`
	);
	console.log(
		`amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`
	);
	console.log("====================");
});

Filter By Mint

import { address, createSolanaRpc } from "@solana/kit";

const rpc_url = "https://api.devnet.solana.com";
const rpc = createSolanaRpc(rpc_url);

let owner = address("4kg8oh3jdNtn7j2wcS7TrUua31AgbLzDVkBZgTAe44aF");
let mint = address("6sgxNSdXgkEFVLA2YEQFnuFHU3WGafhu9WYzXAXY7yCq");

let response = await rpc
	.getTokenAccountsByOwner(owner, { mint }, { encoding: "jsonParsed" })
	.send();

response.value.forEach((accountInfo) => {
	console.log(`pubkey: ${accountInfo.pubkey}`);
	console.log(`mint: ${accountInfo.account.data["parsed"]["info"]["mint"]}`);
	console.log(
		`owner: ${accountInfo.account.data["parsed"]["info"]["owner"]}`
	);
	console.log(
		`decimals: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["decimals"]}`
	);
	console.log(
		`amount: ${accountInfo.account.data["parsed"]["info"]["tokenAmount"]["amount"]}`
	);
	console.log("====================");
});
