I tried it yesterday and up to now, I can't. The pop up keeps disappearing every time I click "WITHDRAW" button.
Account number must be a sequences 35 alphanumeric characters with no spaces. optionally starting with 1W
I added 1W prefix to my recipient btc address but nothing works.
Hello!
This is a know bug with Google Chrome. Please use an online version - https://waveswallet.io with firefox or google chrome (try to reload your wallet).
And please use only WITHDRAW button for external Bitcoin network
Tried https://waveswallet.io/ Same result. Nothing happens still.
What is this attachment for when sending btc to external address, can i leave it blank?
I'm not sure why you are still having difficulties withdrawing. I can answer your second question about the attachment field. It is used for some transactions (usually Waves related to direct funds to a certain wallet), but in this case you don't need to include anything. You can leave it blank.
