Why a person reviews every withdrawal
This exchange does not auto-broadcast payouts. Review is a feature, not a glitch.
The model
Withdrawals are human-reviewed before they are sent. That is described on Security and in the product itself. It exists so a stolen session cannot empty the book in 30 seconds without a pair of eyes.
Typical review looks at: destination format vs network, account flags, amount vs history, and whether the request looks like the account holder.
How long
There is no SLA printed as “always 8 minutes”. Quiet hours and a large first withdrawal take longer than a small repeat to an address you have used. If review is taking far longer than a normal business window, use Live chat with the withdrawal id from the Withdraw page.
Auto-payouts
Some small withdrawals may be sent automatically. Everything else goes through review — that is normal.
What review will not do
Reviewers will not change the destination because you “meant another wallet”. They will not send on a different network than you selected. If you pasted the wrong address, submit a support request before it is sent — once it is sent, the chain does not undo it.
