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 2021-08-21: The provider stated here that was discontinued and its successor is
So the provider contacted us and cleared many issues we had in our first review. Let’s see how far we get this time …
First thing we notice is that there are still no build instructions on the GitHub page but according to above issue it’s simple enough:
The version we got from Google Play is this:
$ sha256sum BLW.apk ffcffa9d3053590b98f845622ab5a4748023245fbacc48f6798ca9ff753f86c6 BLW.apk $ apktool d -o BLW BLW.apk $ cat BLW/apktool.yml | grep "versionCode\|versionName" versionCode: '150' versionName: 0.4.4

Which is again the known issue from last time: The gradle version is outdated. It should be 3.1 or above but is defined as
# cat build.gradle | grep "tools\.build" classpath 'com.android.tools.build:gradle:2.3.0'
So if there is a good reason for using an old gradle version (2.3 is from early 2015), the team should explain that.
Sadly we again fail to compile due to lack of sufficiently clear build instructions and come to the verdict not verifiable.
We encountered a build error while compiling from source code!
As part of our Methodology, we ask:Can the product be built from the source provided? If not, we tag it Build Error!
Published code doesn’t help much if the app fails to compile.
We try to compile the published source code using the published build instructions into a binary. If that fails, we might try to work around issues but if we consistently fail to build the app, we give it this verdict and open an issue in the issue tracker of the provider to hopefully verify their app later.
