Help spread awareness for build reproducibility

Please help us spread the word, asking Guarda Crypto Wallet: Bitcoin, Ethereum, Ripple 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

This wallet - com.crypto.multiwallet according to their applicationId, “Moxi wallet” according to the first sentence of their description on Google Play and “Guarda Wallet – for Bitcoin, Ethereum, etc.” according to the app name -

doesn’t have access to your private keys …

Moxi wallet doesn’t have access to your keys and does not store your funds,

or do they? Here is the next sentence from the Google Play description:

they are stored offline. We provide a wallet’s backup for extra safety.

That sounds a lot like the provider keeps a copy of your private keys, does it not?

Yet under features they explicitly claim:

– Non-custodial wallet. We do not store your money.

Also good to know:

This app does not mine cryptocurrency.

So maybe the confusion above is just a language barrier thing. We will assume for now that the wallet is in fact non-custodial and the backup scheme actually does work without them having access. In a deeper review, this would certainly be one of the first points to check.

Looking for source code, we found a link to the company GitHub and from there to a repository named guarda-android-wallets - very promising.

As it turns out, “guarda-android-wallets” can be used to compile single coin wallets but no app with the application ID com.crypto.multiwallet. In fact a search over all of GitHub didn’t yield results neither.

Without source code available, our verdict is: not verifiable.


Verdict Explained

No source code found

Without public source available, this app cannot be verified!

This verdict means that we could not find any source to compile the app from. Internally the company might do everything right but as we can't verify it, there is nothing protecting the user from an exit-scam where the provider releases an app that leaks the keys to the servers.

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.
