We found these ways of contacting the developers:
The following Analysis is not a full code review! We plan to make code reviews available in the future but even then it will never be a stamp of approval but rather a list of incidents and bad coding practice. We cannot find and tell you all the dark secrets the wallet providers might have.
Do your own research!
Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.
From their FAQ:
Wallet is a user-custodied digital currency wallet and DApp browser.
so for us the next step would be to find the source and reproduce the app …
On the same page there is a link to GitHub but none to the actual repository. Neither is there on the Playstore description.
Here is the list as we found it with the only three descriptions underlined in green, none of which sounds much like an Android wallet:
Tiny correction … some of the projects have empty READMEs.
So from the names, the only two repositories that might contain relevant code
CBHTTP, both of which contain a folder called
An Android app has an ID and this ID has to be referenced in its source code, so
at this point we search for this app’s ID
within the organization
which yields zero results.
Searching all of GitHub we do find the string
for example but as this is not linked by the company and two years old, we will
not try to build it to verify a recently updated app.
This is the point where we come to the verdict not verifiable given there is no public source code to build the app from.
Not verifiable: No Open Source Code found
This verdict means that we could not find any source to compile the app from. Internally the company might do everything right but as we can't verify it, there is nothing protecting the user from an exit-scam where the provider releases an app that leaks the keys to the servers.
The app cannot be independently verified. If the provider puts your funds at risk on purpose or by accident, you will probably not know about the issue before people start losing money. If the provider is more criminally inclined he might have collected all the backups of all the wallets, ready to be emptied at the press of a button. The app might have a formidable track record but out of distress or change in management turns out to be evil from some point on, with nobody outside ever knowing before it is too late.
