Hello @qtldev,

While your app looks great, I would be VERY reluctant to use it!

1. I do not see any valid reason to provide my owner key
2. As it also requires the active key, the  code should be open-sourced or at least fully auditable.

When dealing with crypto, security comes first before utility. 

This said, great to have more passions devs in our ecosystem. I wish you all the best.
