We could not verify that the provided code matches the binary!

As part of our Methodology, we ask:

Is the published binary matching the published source code?

If the answer is "no", we mark it as "Not reproducible from source provided".

Published code doesn’t help much if it is not what the published binary was built from. That is why we try to reproduce the binary. We

  1. obtain the binary from the provider
  2. compile the published source code using the published build instructions into a binary
  3. compare the two binaries
  4. we might spend some time working around issues that are easy to work around

If this fails, we might search if other revisions match or if we can deduct the source of the mismatch but generally consider it on the provider to provide the correct source code and build instructions to reproduce the build, so we usually open a ticket in their code repository.

In any case, the result is a discrepancy between the binary we can create and the binary we can find for download 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 binary 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 product 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 product 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.

But we also ask:

Is the product still supported by the still existing provider?

If the answer is "no", we mark it as "Not functioning anymore".

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.

Help spread awareness for build reproducibility

Please help us spread the word, asking Haven - Private Shopping 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 

Update: @StevieZollo sent a tweet:

@WalletScrutiny @LeoWandersleb it looks like you reviewed @HavenPrivacy the day before it went open source. You can find its source code here: https://github.com/OpenBazaar/haven

so we can check its source code after all. Let’s see how that goes:

Just in case, we reviewed their website again if this is the official repo but there is no link to it, so that doesn’t leave us with much hope. Also: Unless the provider endorses this repository, you should not assume it is anything official or trustworthy! Anyway …

So there is essentially only one revision as far as the Android app goes. Changes to license or readme should not affect the app on Android itself. The missing tag will be a problem later on though.

root@4be0f50e58d3:/mnt# apt install nodejs npm -y
root@4be0f50e58d3:/mnt# npm install -g npm yarn
root@4be0f50e58d3:/mnt# yarn
root@4be0f50e58d3:/mnt# apt install curl
root@4be0f50e58d3:/mnt# yarn
root@4be0f50e58d3:/mnt# find . | grep '\.env'

At this point, the build instructions read

Copy .env file to the root directory

but according to find . | grep '\.env' there is no .env file anywhere. The instruction:

The env file should look like this:


looks like the provider is not sharing all details necessary to build this app but let’s see what happens …

It doesn’t get better. Next we are supposed to

Copy those files into havenBuildConfigFiles folder:


and again those are not files provided by the company.

So to little surprise, compiling doesn’t go all too well:

root@4be0f50e58d3:/mnt/android# cd android/
root@4be0f50e58d3:/mnt/android# ./gradlew clean assembleRelease

At this point we give up and give the verdict not verifiable.
