Help spread awareness for build reproducibility

Please help us spread the word discussing build reproducibility with eXchangily DEX Bitcoin Wallet & Crypto Wallet  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 

This app is a self-custodial Bitcoin wallet:

With eXchangily, you own and control your private key, ensuring your crypto assets are kept in your wallet, giving you absolute control and 100% autonomous ownership.

They are also open source:

FAB and eXchangily are open source projects, unlike other exchanges we have nothing to hide, anyone can see our code at any time.

Notably their website does not link to this Play Store app!

But unfortunately there are no build instructions and Emanuel failed to build it and I have no further ideas to make it build after all. This app is not verifiable.

Verdict Explained

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.

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.
