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.

The Analysis

Coinomi Wallet :: Bitcoin Ethereum Altcoins Tokens claims to be non-custodial but we cannot find any source code on their official GitHub page.

Our verdict: This app is not verifiable.

Further observations

In terms of security issues, Coinomi had the worst kind of bug that luckily did not lead to known financial losses: The 12 word backup was being sent to a remote server.

Apparently the issue was only in the desktop version of the software. If yo want to learn more, read Coinomi’s official statement or search the web for “coinomi security issues” or “coinomi spell checker” for third party interpretations of the issue.

Verdict Explained

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.
