SLIP-39 from BIP-39

[dkbit98]

I found one interesting python SLIP-39 project that makes it easy for everyone to generate and backup mnemonics in SLIP-39 format that is compatible with Trezor hardware wallets.
It's also possible to convert your existing BIP-39 backup to a much more robust SLIP-39 backup, while keeping all your wallets and addresses.
This would be very useful in case if you have hardware wallets that don't support SLIP-39, like Trezor One for example.
With this app you can break your BIP-39 in multiple parts or groups and recover them when you need it.



This project is open source and you can find more details with instructions on their website and github page:

That's a nice find. Did you have a look at the code? Is it trustable?

Before I would use it, I would want to inspect it myself to verify it doesn't have some shady parts. As the old mantra in crypto goes: don't trust, verify! (Considering my rather low coding skills it'll take me quite some time for verification.)

Next is that the app and GUI need to be fully able to be build from the Github code, ideally the builds are reproducible. Not sure if reproducibility of compiled apps is currently possible (so far I didn't have time to look and check). I won't run untrusted or unverified code/apps on any of my systems that come close to some of my crypto stuff.

It's good more tools show up dealing with SLIP-39. Let's see how this tool stands the test of time.

This is open source tool, so anyone can check the code before using it.
If you want more information about the project than better ask developer Perry Kundert, but I expect this toll will be more useful in future when more wallets adopt SLIP39.
