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.
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:
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 email@example.com:COINiD/COINiDWallet.git $ cd COINiDWallet/ $ git tag v1.6.0 v1.7.0 v1.7.2 v1.7.3 v1.7.4 v1.7.5 $ git checkout v1.7.5 $ docker run --volume=$PWD:/mnt --workdir=/mnt --rm -it beevelop/cordova bash root@c0a4b6139564:/mnt# echo "export const p2pCommonSecret = '';export const encryptPrivateSalt = '';export const pinSecret = '';" > src/config/secrets.js root@c0a4b6139564:/mnt# apt update ; apt install python -y root@c0a4b6139564:/mnt# npm install root@c0a4b6139564:/mnt# yes | $ANDROID_HOME/tools/bin/sdkmanager "platforms;android-28" root@c0a4b6139564:/mnt# cd android/ root@c0a4b6139564:/mnt/android# ./gradlew clean :app:assembleRelease ... > Task :app:bundleReleaseJsAndAssets warning: the transform cache was reset.

And that’s where we give it up and conclude with the verdict: not verifiable
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.
