Help spread awareness for build reproducibility
Please help us spread the word, asking Shango Lightning 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.
This app features
No hassle, instant setup. The Shango service offers you a FREE, secure LND cloud server instance paired to your device, without requiring you to master advanced technical skills and command line tools.
but although they set those servers up, they claim:
Note: Shango doesn’t hold any funds, does not store any user identifiable information, does not have access to any private keys nor perform any transactions. It relies on and sends commands to the open source daemon LND to perform Lightning network operations.
so that is certainly weird. Maybe the website is more informative …
Turns out, the website uses a ten months expired ssl certificate and greets us with:
Warning: Potential Security Risk Ahead
Not exactly inspiring confidence. So we ignore the warning for you and get rewarded with a link to their GitHub with the label:
Don’t trust us, verify the code. All source files on Github.
but there we see some 20 files that are definitely not an Android app and no activity in over a year.
This app is for all we can see 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.
