The Analysis ¶
Update 2022-02-09: This app is no more.
Note: This is the PRO version for:
- One Stop digital asset management
- Two secure asset management solutions
- Manage assets with partners
- Institutional, Multi-signature, Numerous Currencies
- Team Property, Team Confirmation
- Suitable for multiple parties’ co-management. Avoid assets loss caused by single private key missing. Offer a better solution to multiple parties funding co-managements.
- ‘m-of-n’ signatures. Set ‘n’ total private keys and requires ‘m’ signatures in authorizing a transaction.
We downloaded the app. Our user credentials are the same with the other wallet.io app.
After sign-in, we are presented with two options:
- Group multisig wallet
- Individual multisig wallet
We opted for the individual multisig wallet.
We then filled up the following fields:
- Wallet name
- Private key generation:
- Wallet.io hardware
- Safe-keeping of the third private key
We were able to locate their github, but as of this moment, it seems to be outdated, with only six commits in the past year. Additionally, no repositories were related to wallet.io’s mobile app.
This app is self-custodial, but the source code is not verifiable.
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.
But we also ask:Is the product still supported by the still existing provider? If not, we tag it Defunct!
Discontinued products or worse, products of providers that are not active anymore, are problematic, especially if they were not formerly reproducible and well audited to be self-custodial following open standards. If the provider hasn’t answered inquiries for a year but their server is still running or similar circumstances might get this verdict, too.
