Set Appropriate Expiration

Use expiration for time-sensitive payments:

// 30 minutes for checkout flows
const wallet = await client.createWallet({
  network: 'trc20',
  crypto: 'USDT',
  expiresInMinutes: 30,
  metadata: { orderId },
});

// No expiration for subscription top-ups
const wallet = await client.createWallet({
  network: 'trc20',
  crypto: 'USDT',
  // No expiresInMinutes = never expires
  metadata: { userId, type: 'subscription_topup' },
});
