Trezor Safe 3 incompatible with Monero?

Third party wallets
1

The official documentation claims that Safe three is compatible with Monero:

I cannot see it in the list of supported hardware devices in the Monero GUI. The only Trezor device that’s supported is Model T.

monero-gui-trezor
monero-gui-trezor937×624 44.3 KB

The Exodus wallet also seems only to support Model T:

I only purchased Safe 3 to use with Monero. How do I do that? Can I receive a refund, possibly an exchange for Model T?

I use my safe 3 with monero GUI all the time.

Just select model T and it’ll accept it, done.

It’s not working for me. Produces an error. What OS do you use?

4

Linux mint (ubuntu).
Been doing it for sometime, no problems, are you using the latest version monero gui.

Does the safe 3 work OK in trezor suite?

5

Yes, the Safe 3 works well in Trezor Suite. I set it up and all. I’m using Void Linux. I’ll poke around more and see if I can get the Monero GUI working with it.

6

Yes just tested, works fine for me.
Have you tried the feather wallet appimage?
maybe have better luck with that?
I take it the trezor bridge and udev rules are all good?
I would have thought they would be cos it works with trezor suite…

edit: what is the error say?

8

also on the latest version of monero gui, ‘safe 3’ is actually listed on the drop down.
my version is 0.18.3.2 , what’s yours?

Yes, I had an older version of the Monero wallet. After upgrading, I can now see Safe 3. However, I am still not able to connect. I get this error:

perhaps this is something to do with your OS…
permissions related maybe?

Sorry can’t be of much further help.
Edit: I suspect you’d get the same result with a model T

If you use Trezor Safe 3 with Monero GUI all the time, then do you have an answer to this question:
"How do you get your XMRs if your Trezor breaks down and you cannot have another Trezor HW?!

In other words:
"How do you convert your 12- or 24-word Trezor seed to a 25-word Monero seed that you can use in a Monero wallet app like monerujo for Android, or Monero GUI app for desktop itself by restoringa wallet from 25-word seed?

here is a tool that can do this: monero-agent/PoC.md at master · ph4r05/monero-agent · GitHub

another option is building the Trezor emulator and recovering your seed into that

Oh-lala - both solutions for IT specialists… :frowning:

I think there should be a tool like the “ian coleman” tool - html based and ready to use for normal users.

Even though many crypto enthusiasts are IT’lers, there are even more crypto enthusiasts who are no programmers for a living. With all due respect - from a company like Trezor that implements the Monero support in such a non-standard proprietary way (yes open-source, but still proprietary), I’d at least expect to provide an easy-to-use tool to provide a gateway (conversion) to the standard ways of accessing one’s XMR coins. And obviously, “standard” for Monero is the known 25-word-seed format.

So since the license of the ian coleman tool is open, the natural way forward would be a fork of that tool for converting from trezor 12/24 word seed to Monero 25-word seed.
