Yes, this is obtainable. Some software providers keep certain parts and patches of their software in private repositories for specific reasons
You may want to read this from Exodus
Although Exodus is built on many open-source components, there are components of Exodus that are not open-source.
Exodus publishes some open-source work used in Exodus on GitHub. You can view the source code, history, and continually published updates by visiting: Exodus Movement.
https://www.exodus.com/support/en/articles/8598678-is-exodus-open-source?Exodus Wallet isn't open-source regardless of what their people claim or not. Unless something has changed, you can't build the binaries yourself using publicly available code. A partially open-source app, where some components are open-source while others aren't can't be classified as open-source software. Ledger used to do that and called themselves open-source. The firmware that runs on each hardware wallet of Ledger is closed-source. They conveniently avoid to mention this. Their native Ledger app and the coin apps that you need to install on your device are open-source, but that's not enough. When you consider the entire package, it's closed-source software.
Yeah, actually we were differentiating between an open code and an open-source earlier and exodus happens to fall into the category of open code. Most essential components are hidden in private repositories, so we cannot call it open-source, but an open code, but I didn't see it as to be totally categorized as close source. However, another wave of thought have flashed through my mind while I read your write-up.
Is there such situation whereby a wallet provider making every component of their code base (including the binaries) public, but restricting the legal rights of it being reproduced? This is to be more precise in my categorization between open code and closed source.
It turns out that not all modern hacks and thefts from hardware wallets are related to AI these days. You may have heard that yesterday news came out about the largest lawsuit, worth 500 million, filed by victims of a long‑ago Ledger hack.
I saw the newsflash in my notification panel during my off-screen time, I'll visit it later and revert. It is really worth discussing.
