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 ¶
On Google Play we read
As a multi-asset web wallet, users are in full control of their private keys
so we assume this app is non-custodial.
On their Website we read again
Own Your Private Keys
Private keys for cryptocurrency addresses are created client side through a proprietary method and are never stored or sent back to our servers
which is actually very scary. âProprietary methodâ means non-standard method, so if this wallet stops working, there is no way to get your funds recovered on a different wallet.
On their website there is a link to a GitHub repository but that only contains one text file and no code.
The app is closed source and thus not verifiable.

Verdict Explained
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 usersâ funds might actually be lying. In the spirit of âDonât trust - verify!â you donât 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 doesnât 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 doesnât 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 providerâs word.
âUp to dateâ 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 productâs 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 wonât use the code without giving it careful scrutiny.
