The Analysis ¶
(Analysis from Android review)
DotWallet is a lightweight non-custodial wallet built on the Bitcoin SV protocol. It provides quick registration and login using mobile phone numbers, email, and third party providers like Google, Facebook and WeChat.
It supports the sending, receiving, and storage of multiple digital currencies including BSV, BTC, and ETH. Powered by BSV’s tokenization technology, users can send BTC, BSV and ETH instantly using 0 confirmation transactions.
We downloaded the app and found support for BTC with send and receive functions. The mnemonics are only generated for BSV wallets. This is indicated on this article:
The BSV wallet supports backup mnemonics, while the BTC and ETH wallets are generated powered by BSV tokenized techniques, which has the core advantages of instant payment, lower handling fees, and 100% chain auditability (Check details);
The mnemonics of the DotWallet can be restored in the BSV wallet that supports BIP44. The key derivation path is: m/44’/0’/0’. Currently, the function of importing mnemonics is under development.
As it describes itself, it is a self-custodial bitcoin wallet that supports BSV, BTC and ETH. We searched for the Google Play appID on github but have yielded 0 results.. We were not able to locate the source code for this app.
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.
