Retry Strategy

async function requestWithRetry(fn, maxRetries = 3) {
  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      return await fn();
    } catch (error) {
      const shouldRetry =
        error.code === 'HD_WALLET_UNAVAILABLE' ||
        error.code === 'RATE_LIMIT_EXCEEDED' ||
        error.status >= 500;

      if (!shouldRetry || attempt === maxRetries) {
        throw error;
      }

      // Exponential backoff
      const delay = Math.pow(2, attempt) * 1000;
      await new Promise(resolve => setTimeout(resolve, delay));
    }
  }
}

// Usage
const wallet = await requestWithRetry(() =>
  client.createWallet({ network: 'trc20', crypto: 'USDT' })
);
