Help spread awareness for build reproducibility

Please help us spread the word, asking Unstoppable - Invest In Crypto to support reproducible builds via their Twitter!

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

Here is the output using our test script on the binary from Google Play:

Results:
appId:          io.horizontalsystems.bankwallet
signer:         c1899493e440489178b8748851b72cbed50c282aaa8c03ae236a4652f8c4f27b
apkVersionName: 0.20.0
apkVersionCode: 41
apkHash:        1a98f8bec96d1e50b6aa6fe2cb9116b16ec1b48f71241c9081ac67dadc7166d9

Diff:
Files /tmp/fromPlay_io.horizontalsystems.bankwallet_41/apktool.yml and /tmp/fromBuild_io.horizontalsystems.bankwallet_41/apktool.yml differ
Only in /tmp/fromPlay_io.horizontalsystems.bankwallet_41/original/META-INF: MANIFEST.MF
Only in /tmp/fromPlay_io.horizontalsystems.bankwallet_41/original/META-INF: RELEASEK.RSA
Only in /tmp/fromPlay_io.horizontalsystems.bankwallet_41/original/META-INF: RELEASEK.SF
Files /tmp/fromPlay_io.horizontalsystems.bankwallet_41/smali_classes2/io/horizontalsystems/bankwallet/core/providers/AppConfigProvider.smali and /tmp/fromBuild_io.horizontalsystems.bankwallet_41/smali_classes2/io/horizontalsystems/bankwallet/core/providers/AppConfigProvider.smali differ

Unfortunately that is one file too many. Upon closer inspection it looks totally benign though:

$ diff /tmp/from{Play,Build}_io.horizontalsystems.bankwallet_41/smali_classes2/io/horizontalsystems/bankwallet/core/providers/AppConfigProvider.smali
205c205
<     const-string v0, "unstoppable.support@protonmail.com"
---
>     const-string v0, "support.unstoppable@protonmail.com"

so while we do not ring the alarm over this, we unfortunately have to give it the verdict not verifiable until they produce a revision with the right email address.

Thank you to Horizontal Systems for repeat donations:

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.
