Help spread awareness for build reproducibility

Please help us spread the word discussing build reproducibility with Bitcoin Wallet for COINiD  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 does not reveal much information on Google Play but

  • Complete Control
  • Hierarchical Deterministic

sounds like the standard non-custodial wallet.

The FAQ on their website is more explicit:

Do my private key ever leave my device? No, your private key never leaves your device. You are in full control of your private key.

And in the FAQ we find this gem:

Do you provide deterministic builds? Since we need to distribute the app via the App Store that is not possible. The source is however available on our Github so that anyone can review and compile it.

So let’s give it a try anyway …

The current version is 1.7.5. The build instructions in their entirety are:

COINiD Wallet

Proper readme coming soon. If you have any questions you can contact us on our Telegram or via Email.


We are currently not including the secrets.js in the repo. If you want to compile the wallet to test it you need to add the following to src/config/secrets.js.

  export const p2pCommonSecret = '';
  export const encryptPrivateSalt = '';
  export const pinSecret = '';

That is not good but let’s see:

$ git clone git@github.com:COINiD/COINiDWallet.git
$ cd COINiDWallet/
$ git tag
$ git checkout v1.7.5
$ docker run --volume=$PWD:/mnt --workdir=/mnt --rm -it beevelop/cordova bash

And that’s where we give it up and conclude with the verdict: 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.

But we also ask:

Was the product updated during the last year? If not, we tag it Stale!

Bitcoin wallets are complex products and Bitcoin is a new, advancing technolgy. Projects that don’t get updated in a year are probably not well maintained.

This verdict may not get applied if the provider is active and expresses good reasons for not updating the product.

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.
