Without public source of the reviewed release available, this product cannot be verified!

As part of our Methodology, we ask:

Is the source code publicly available?

If the answer is "no", we mark it as "No source for current release found".

A wallet that claims to not give the provider the means to steal the users’ funds might actually be lying. In the spirit of “Don’t trust - verify!” you don’t want to take the provider at his word, but trust that people hunting for fame and bug bounties could actually find flaws and back-doors in the wallet so the provider doesn’t dare to put these in.

Back-doors and flaws are frequently found in closed source products but some remain hidden for years. And even in open source security software there might be catastrophic flaws undiscovered for years.

An evil wallet provider would certainly prefer not to publish the code, as hiding it makes audits orders of magnitude harder.

For your security, you thus want the code to be available for review.

If the wallet provider doesn’t share up to date code, our analysis stops there as the wallet could steal your funds at any time, and there is no protection except the provider’s word.

“Up to date” strictly means that any instance of the product being updated without the source code being updated counts as closed source. This puts the burden on the provider to always first release the source code before releasing the product’s update. This paragraph is a clarification to our rules following a little poll.

We are not concerned about the license as long as it allows us to perform our analysis. For a security audit, it is not necessary that the provider allows others to use their code for a competing wallet. You should still prefer actual open source licenses as a competing wallet won’t use the code without giving it careful scrutiny.

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.

We downloaded and tried to register an account but was not able to. We did not receive the SMS-OTP code. We were not able to access the wallet’s features.


This wallet claims to have two versions or modes: CeFi (custodial) and DeFi (self-custodial). We searched Github for the Zam appID of zam.wallet but did not find a relevant repository related to the Zam wallet.

There is a linked repository which appears to be a self-custodial prototype for a wallet api.

The description reads as follows:

A safe wallet to store, manage, send, and receive digital assets. Users need an easy way to access and manage their digital assets. ZamWallet is an application for iOS and Android that allows users to store, access, manage, send, and receive crypto directly from their mobile phones.

We could not find the source for the app as reported in gitlab issue #367.

The linked github org don’t contain repo that publish sources for mobile apps, didn’t opened related issue on some of their github repos.
