The Analysis ¶
This app’s description contains
Users’ self-control for private key to manage assets
which sounds like a claim to being non-custodial.
Also on their FAQ we read:
Is my digital assets safely stored in ViaWallet? ViaWallet is a subsidiary brand of ViaBTC, which was founded in May 2016 as an innovation-intensive startup dedicated to cryptocurrency with rich technological prowess and experience in global operation of blockchain industry. With the most state-of-the-art Fintech, we aims to provide a self-controlled and easy-accessible multi-cryptocurrency wallet across devices, safeguarded with industry-leading security for your digital assets.
which says “self-controlled” but nowhere do we find a hint at this wallet’s source code. We assume it’s claiming to be non-custodial but remain with the verdict: not verifiable.
Without public source of the reviewed release available, this app cannot be verified!
As part of our Methodology, we ask:Is the source code publicly available? If not, we tag it
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 app 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 app’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.
