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 ¶
- Electrum based
- USB device with built in VPN (1 year subscription)
- Linux Ubuntu 18.04 based OS
- 18GB of personal encrypted file storage
- Can be activated through an activation code sent by provider through email
- The Keep Activation App automatically sets up VPN, personal encrypted email, public/private key pair and password encrypted storage
The device is basically a Live Pendrive Linux (Ubuntu 18.04) with pre-installed Electrum Bitcoin Wallet. In other words, it’s a standard USB pendrive with custom, bootable software.
When you order a Keep Stick we send you a Keep USB stick via post and an Activation Key code via email. When you receive your stick you enter the code as part of the built in secure activation process to create your personal encrypted account on the stick. This process also automatically sets up your connected VPN and personal encrypted email services.
The device’s Keep App automatically downloads security updates and other new features
Although it is standard practice to receive security updates to an OS or to an app, having this done on the same environment as a Bitcoin wallet can introduce risks. First, the updates that the custom OS downloads means that the provider has to be trusted.
The open source applications we bundle with Keep Stick come with built in help and/or links to online documentation.
Since we believe that Keep Stick may have customized some of these applications, we need to know if their customizations are open source as well.
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 not, we tag it No Source!
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.
