I have done that several times no cancel button @gateio

Answer 2: Unfortunately, once a transaction has been sent, there is no way to cancel it. You will just have to wait for the transaction to be processed. It is important to double-check that all information is correct before sending a transaction, as it cannot be undone once it has been sent. You may want to consider setting up a reminder for yourself to double-check your information before sending any future transactions.

I see. If cancel button isnt there anymore then it means your transaction has been sent and being processed. Please wait patiently.
