EX.IO withdrawals only available for accounts that have undergone fiat whitelisting. Withdrawal failures may occur by the following reasons:
1) The bank account details you provided for fiat withdrawal, including the bank number, branch number, etc., may be incorrect.
2) Inter-bank transfers might fail due to issues such as risk control imposed by the bank.
3) There may be system-related factors from other platforms or banks, such as bank system upgrades.
4) The necessary information needed for cross-border transfers may vary between banks in different countries or regions, potentially leading to longer processing times.
If you encounter any issues during your fiat withdraw, please contact EX.IO official customer service at cs@ex.io.
