First, what are the advantage of using this wallet than the existing one like myethereum and metamask?
With Endpass, transactions dont get stuck
What are the authentication that transaction made will not get stuck?
Endpass will back up your data to our secure cloud
What information stored on your server? If the plain text private keys or seed are stored on your server then the wallet is not safe at all, because nothing is unhackable.
Endpass is super mega secure. It includes 2FA, email confirmation and its fully decentralized
What confirmations does this wallet require? Confirmation when sending funds? or just when logging in.
All of the wallet code is available on Github to inspect.
So where's the link of github repo, I can't see it on your site.
