Transaction hash for withdrawals usually appears almost immediately after you confirm your withdrawal.
Should in case it doesn’t appear after a few minutes, kindly check the current withdrawal performance speed on the system health page for the average processing time of the coin.
If the withdrawal remains pending longer than the average processing time specified on the system health, kindly cancel the withdrawal by clicking on the red cancel icon on the right from the withdrawal status then try the withdrawal again.
If the issue persists, kindly raise a Support ticket and your issue will be attended to immediately.
