Help spread awareness for build reproducibility
Please help us spread the word, asking Vidulum - Multi-Asset Cryptocurrency Wallet 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.
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. “Proprietary method” 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.
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.
