Disclaimer

The following Analysis is not a full code review! We plan to make code reviews available in the future but even then it will never be a stamp of approval but rather a list of incidents and bad coding practice. We cannot find and tell you all the dark secrets the wallet providers might have.

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.

The Analysis

Enjin: Blockchain & Crypto Wallet description starts promising:

“Your private keys are your own”

They advertise advanced securing techniques among which are:

“An extensive independent security audit and penetration test found no security issues.”

(You can read the report here)

but source code isn’t available on their website. So the user is left with only one choice: trust.

Our verdict: not verifiable.

Other observations

in-app browsing: “ENJOY SEAMLESS BROWSING Interact with any DApp with the single click of a button—without leaving the safety of your crypto wallet.”

looks very advanced, the list of features is tremendous. also an old player: “ABOUT ENJIN Founded in 2009 and based in Singapore, Enjin offers an ecosystem of integrated, user-first blockchain products that enable anyone to easily manage, explore, distribute, and integrate blockchain-based assets.”

on their main page, they advertise advanced securing techniques amongst which are:

  • “An extensive independent security audit and penetration test found no security issues.” (with ability to read the report)
  • “Custom ARM instructions ensure that sensitive data is instantly deleted from your phone’s memory.”
  • “Enjin Keyboard. Built from scratch to protect you from any form of data sniffing or keyloggers.”

Verdict Explained

Not verifiable: No Source Code found

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.
