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.

If you find something we should include, you can create an issue or edit this analysis yourself and create a merge request for your changes.

The Analysis 

Update 2021-06-16: It’s been six weeks this app is not on the App store. If it should return, please open an issue on our issue tracker!

Emanuel looked into this wallet a bit as it claims association with a pretty prominent website - bitcoin.org and indeed it is endorsed by Cobra-Bitcoin, the owner of bitcoin.org.

As Emanuel so far doesn’t write analysis, I’ll reproduce his reproduction of this wallet to also compare the result with what we get from Google Play:

mkir /tmp/testbitcoinorg
cd /tmp/testbitcoinorg
podman run --rm --volume $PWD:/app --interactive --tty frolvlad/alpine-glibc
apk update
apk add --no-cache openjdk8 git yarn
export ANDROID_SDK_ROOT="/home/appuser/app/sdk"
export ANDROID_HOME="/home/appuser/app/sdk"
export NODE_ENV="production"
mkdir -p "/home/appuser/app/sdk/licenses" "/home/appuser/app/bitcoinorg/"
printf "\n24333f8a63b6825ea9c5514f83c2829b004d1fee" > "/home/appuser/app/sdk/licenses/android-sdk-license"
cd /app
git clone https://github.com/bitcoin-dot-org/BitcoinWalletMobile/
cd BitcoinWalletMobile
git checkout v1.0
yarn install --frozen-lockfile --production
cd android
sed -i '/org.gradle.jvmargs/s/^#//g' gradle.properties
./gradlew assembleRelease
./gradlew bundleRelease
cp app/build/outputs/apk/release/app-release.apk .
cp app/build/outputs/bundle/release/app-release.aab .

So far so good, the apk and the aab got created successfully but … Emanuel stated that they use aab and we so far only could reproduce apk builds.

Let’s see how the apk build looks like:

$ unzip /path/to/Bitcoin\ Wallet\ 1.0\ \(org.bitcoin.wallet\).apk -d fromGoogle

which is certainly not a match but aab would allow certain content to be stripped and stuff missing in the version from Google Play could probably not do harm. How’s the diff ignoring those and the META-INF lines?

$ diff --recursive --brief from* | grep -v "$Only in fromBuild" | grep -v META-INF
Files fromBuild/AndroidManifest.xml and fromGoogle/AndroidManifest.xml differ
Only in fromGoogle/assets: index.android.bundle
Files fromBuild/res/drawable-ldpi-v4/ic_launcher_foreground.png and fromGoogle/res/drawable-ldpi-v4/ic_launcher_foreground.png differ
Only in fromGoogle/res/xml: splits0.xml
Files fromBuild/resources.arsc and fromGoogle/resources.arsc differ
Only in fromGoogle: stamp-cert-sha256

which is still a lot. We have to give up here and hope for the provider to help with build reproduction. In the meantime this app is not verifiable.

Verdict Explained

This app went out of business ... or so. Read the analysis for details.

As part of our Methodology, we ask:

Is the product still supported by the still existing provider? If not, we tag it Defunct!  

Discontinued products or worse, products of providers that are not active anymore, are problematic, especially if they were not formerly reproducible and well audited to be self-custodial following open standards. If the provider hasn’t answered inquiries for a year but their server is still running or similar circumstances might get this verdict, too.
