Our last analysis was done on 29th August 2020 based on data found in their Google Play description and their website and their source repository. We discuss issues with the provider here. Our verdict was Not reproducible from the source provided (details below).

We found these ways of contacting the developers:

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

Update: Alan Gabriel offered a link to this repository in our issue tracker.

Indeed that looks like the wallet’s source code but the Readme.md doesn’t look like a well maintained project. The first line <<<<<<< HEAD is the residue from a merge gone bad.

Given the last change is more than 2 years old and it looks like an abandoned project and there are no build instructions for a production release, we give up after this error:

$ git clone https://github.com/Lunes-platform/Wallet-mobile
$ cd Wallet-mobile/
$ docker run -it --volume $PWD:/mnt --workdir /mnt --rm walletscrutiny/android:4 bash
# apt update && apt install nodejs npm -y
# npm install
# cd android/
# ./gradlew assembleRelease
...
FAILURE: Build failed with an exception.

* Where:
Build file '/mnt/node_modules/react-native-linear-gradient/android/build.gradle' line: 21

* What went wrong:
A problem occurred evaluating project ':react-native-linear-gradient'.
> Could not find method compileOnly() for arguments [com.facebook.react:react-native:+] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

and consider it not verifiable.

Verdict Explained

Not reproducible from the source provided The app provider also shares code but we could so far not verify that the published code matches the published app!

This verdict means that the provider did share some source code but that we could not verify that this source code matches the released app. This might be due to the source being released later than the app or due to the provided instructions on how to compile the app not being sufficient or due to the provider excluding parts from the public source code. In any case, the result is a discrepancy between the app we can create and the app we can find on GooglePlay and any discrepancy might leak your backup to the server on purpose or by accident.

As we cannot verify that the source provided is the source the app was compiled from, this category is only slightly better than closed source but for now we have hope projects come around and fix verifiability issues.

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.
