Использование web3.js

import { Connection, PublicKey } from '@solana/web3.js';

const connection = new Connection('https://fra.rpc.orbitflare.com?api_key=YOUR-API-KEY');

// Get token accounts by owner
const owner = new PublicKey('4vJ9JU1bJJE96FWSJKvHsmmFADCg4gpZQff4P3bkLZj');
const programId = new PublicKey('TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA');
const accounts = await connection.getTokenAccountsByOwner(owner, { programId });
console.log('Token accounts:', accounts);

// Get token accounts by owner with analysis
async function getTokenAccountsByOwnerWithAnalysis(
  owner: PublicKey,
  config: { programId: PublicKey; commitment?: string }
) {
  const accounts = await connection.getTokenAccountsByOwner(owner, config);
  
  return {
    accounts,
    analysis: {

        const amount = BigInt(account.account.data.parsed.info.tokenAmount.amount);
        acc[mint] = (acc[mint] || BigInt(0)) + amount;
        return acc;

Примечания

1. Возвращает все токеновые счета, принадлежащие указанному открытому ключу
2. Владелец имеет полный контроль над этими счетами
3. Ответ приходит немедленно, так как читается из текущего состояния
4. Счета могут изменяться при переводах токенов и других операциях
5. Владелец должен быть действительным открытым ключом

​

Рекомендации

1. Используйте подходящий уровень подтверждения в зависимости от ваших потребностей
2. Кэшируйте результаты там, где это уместно, для снижения нагрузки на RPC
3. Отслеживайте изменения в принадлежащих счетах
4. Рассмотрите использование подписки на websocket для обновлений в реальном времени
5. Обрабатывайте сетевые ошибки и выполняйте повторные попытки при необходимости
