Excuse me from asking, but why would anyone want to use this? You've said that the wallet uses public APIs and so, your IP can be tracked, that the users should be extremely cautious etc. You've literally called it the most dangerous wallet, and it's true. There are many things you should be aware of such as your browser extensions, programs that have access to your browser etc.

Sure, it might was a good exercise to code it, but to serve it as a "fast & anonymous wallet"? I think it's just bad. Benignly.
