Can confirm I cannot enter anything in the Receiver Address box either. Tested on 4 different web browsers, including mobile.
The website should go through some internal, behind-the-scenes testing phases before going public, considering there are 3 people so far (4 including me) finding bugs or weird things about your platform. I'm curious about the advantages of it vs Komodo's Atomic DEX too.
If you really want your platform to become a thing, having it public with bugs and possible glitches/errors may turn into a negative overall opinion of it which you wouldn't want to, I believe. I recommend launching a public version only when internal testing phases end with 100% success.
It is not a bug...
Maybe we should have some explainer.
If you want to make an atomic swap, you should make two transactions.
One on ethereum network
One on bitcoin network.
We do use brain wallet, because you have to sign the transaction with your bitcoin key and then to broadcast it.
it is using P2WSH script.
You do not have option to enter bitcoin address, because you have to prepare the raw transaction after that and the one and only way to do it is with brain wallet for now.
I agree that it is not the most secure login method, but If you use it only for the swap and then move your funds somewhere else it is fine + brain wallet stays only in your browser local sotrage so nothing critical could hapen if you do not have some viruses or malicious extensions on your computer.
