I bought a Trezor Safe 3 and I have a few questions

[rdluffy]

I managed to buy my first Trezor Safe 3, until now I had a Ledger Nano S
But I've already noticed that it's different from my Ledger

I did the initial configuration, installed the firmware, wrote down the 20 words and everything was fine

But now here are my questions:

Is it possible to generate BIP39 seeds with the Trezor?
I'd like to create an address (or more) through Trezor, but it would need to be with BIP39 to be able to store it with my cryptosteel

I read some time ago a comment about having 2 BTC addresses on Trezor, how do you do that?
My thought is to have one address with a few satoshis and another with my main wallet

Trezor safe 3 uses bip39 seed phrase as default word standard, you should have done a little check on reviews.
Here is a thread dedicated for Trezor Safe 3

2 btc addresses? Are talking about taproot and Native segwit addresses? Then yes, it supports taproot(bc1p..) and segwit(bc1q..), you can choose the one you want.

I remember I've set up my Trezor safe 3 for BIP39 seed (I don't remember if it was 12 or 24 words), to keep it compatible with other systems/devices (including my old and discontinued Ledger Nano).

I don't have it at hand now to double check, but I've looked up Youtube tutorials and .. just look at this minute: https://youtu.be/C1pAyiEfvy0?feature=shared&t=79
you'll see the more/bottom options.

Just pay attention when you set up.

You can set it up as you want, this is 100% up to your choice and ideas on what you consider safe.

[Charles-Tim]

Did you not see this while setting up your wallet?



I get it from here about Safe 3: https://trezor.io/guides/trezor-devices/trezor-safe-3/get-started-with-the-trezor-safe-3?srsltid=AfmBOoqlctDX6fydHpd4ckItNzXPmc5bfjQvxHMWhN2BCZYAaRJGEf6i

Click on standard seed backup instead of Shamir backup. I do not include that advanced because it supposed not to be there and it is confusing people.

The 20-word phrase you created is Bip-39 compatible.  You can restore it in any hardware or software wallet that supports Bip-39.

I read some time ago a comment about having 2 BTC addresses on Trezor, how do you do that?

Each wallet produces many addresses, far more than just two.  There are also two ways to create additional wallets.  First by creating additional accounts (derivation paths of the same seed phrase) and second by creating a passphrase to extend your seed phrase (i.e. 21st word.)  The first method doesn't add any additional security for the second wallet, but adding an extension to your seed phrase does increase security.

You can use either method to create as many wallets as you like, again, far more than two.

You selected new default SLIP39 with 20 words during the setup, but you can also select BIP39 with 12 or 24 words.
It's easy to reset device and start all over again, with BIP39 this time.

You can a and you should create multiple addresses in Trezor, this is the same for all hardware wallets.
Using one bitcoin address for everything is silly, especially in hardware wallets.

Yes, it's possible to protect/extend your recovery phrase with a passphrase. Note that you've configured a SLIP-39 wallet (Shamir Backup), so you will be accessing a different wallet than a BIP39 wallet, but both protocols support passphrases.

It's important to note that you're using a different standard than BIP39. SLIP-39 (which you are using) isn't compatible with most hardware and software wallets. Below I'll list some wallets that support Shamir Backup (Slip-39):

Hardware wallets other than Trezor that support SLIP-39:
- Keystone 3 Pro
- Passport Prime (not yet released).

Software wallets:
- BlueWallet (import Only)
- Electrum (import Only)
- Sparrow (Import Only)

Sources:
Hardware wallet supports: https://thebitcoinhole.com/hardware-wallets
Software wallets supports: https://thebitcoinhole.com/software-wallets

In other words, you can only recover SLIP-39 wallets in the software wallets mentioned, you can only create wallets in the SLIP-39 standard in hardware wallets that support this feature. This means that if you are thinking of importing the same SLIP-39 backup in hardware wallets such as Ledger, Jade, etc., it'll not be possible, as they aren't compatible with SLIP-39 Shamir backup, you can only use SLIP-39 + Passphrase (hidden wallet) through Trezor or other compatible hardware wallets.

SLIP-39 is not backwards compatible with BIP39, in other words, there is no way to convert a SLIP-39 wallet format to BIP39 or vice versa so that both protocols access the same addresses. So this is a decision that should be carefully considered, BIP39 has greater support and is the standard, but SLIP-39 is gaining more and more acceptance, but I don't believe it will become the standard.

Another important detail that may be interesting for you to make backups strategically is that you can generate a single SLIP-39 backup, and later, you can upgrade to Multi-share Backup (e.g.: 2 of 3). The single-share-backup will remain valid, you can either save it in an ultra-secure location or delete this backup (as long as you have configured it for Multi-share backup), which Trezor itself recommends, but I think it's unnecessary to delete the single backup, since there is a remote chance that you will lose your necessary shares.

Another important detail is that if you have configured your SLIP-39 wallet backup as multi-shared backup, you cannot downgrade to single-share-backup.

Here is a thread dedicated for Trezor Safe 3

I think it's changed, this is the reason I'm asking, because when I set up my Trezor, the 20-word option appeared by default, the default being SLIP-39 

...
I don't have it at hand now to double check, but I've looked up Youtube tutorials and .. just look at this minute: https://youtu.be/C1pAyiEfvy0?feature=shared&t=79

...

Yes, exactly
When I first set it up, I didn't realize there were Legacy Backup Types, this option is quite hidden to tell the truth 
By default they suggest 20 words

Did you not see this while setting up your wallet?

The configuration screen is different now, and that made me confused and not see the options for the BIP39 standard, but now I've found it hehehe

...
The 20-word phrase you created is Bip-39 compatible.  You can restore it in any hardware or software wallet that supports Bip-39.
...

Are the 20 words also compatible with the BIP39?
I got confused now, I thought it was SLIP-39

Yes, it was my mistake not to find the BIP39 option, it was well hidden in this Trezor configuration, they give preference to the 20 words of SLIP 39

Slip39 is entirely different from BIP39. Slip39 is gotten from Shamir secret sharing and it is not related to anything about bitcoin, unlike BIP39.

They are also not compatible. Only wallets that you will be able to recover Slip39 are Slip39 compatible wallets.

The standard is BIP39.

Only how they can be related is that BIP39 can be converted to Slip39 if you use a Slip39 tool for it. Any characters or words can be converted to Slip39 words.

I read some time ago a comment about having 2 BTC addresses on Trezor, how do you do that?
My thought is to have one address with a few satoshis and another with my main wallet

To generate a new address (of one type), you will first need to top up the previous address (of one type) with the N-th amount (this can be a symbolic amount).

For example, you have address 1 (segwit). You need address 2 (segwit). To create address 2, the balance of address 1 must be greater than 0.

In this case, you can create address 1 (native segwit) in parallel, but the principle works here as above. In terms of creating address 2 and so on.

Also, create a hidden wallet, which will increase the total number of addresses by 2 times. This hidden wallet will exist in parallel to the main one.

I'm going to generate some seeds in BIP39 format because I want to store them in a cryptosteel I have here, then I'll delete them and use Trezor normally
Any extra suggestions?

Ah ok, thanks for explanation, it's new for me this Slip39 and I was confused

These are the screens that are currently displayed in the Trezor configuration
See that by default they show the 20-word Slip 39 pattern with much more visibility, and that you have to search a bit to get the seed with the 12- or 24-word BIP39 pattern
That's why I was confused the first time.








I'd like to use this post as an opportunity to ask, do you Trezor owners really use the Trezor Suite or do you use Electrum and Metamask as wallets?

[SFR10]

To generate a new address (of one type), you will first need to top up the previous address (of one type) with the N-th amount (this can be a symbolic amount).

This is incorrect... To generate or rather reveal fresh addresses on Trezor Suite, all you need to do is click on the show full address button and confirm the displayed address on your Safe 3 device ^{[if it matches]}.
^{- Whenever you do the above steps, a new address will become partially visible behind the show full address button.}

I'd like to use this post as an opportunity to ask, do you Trezor owners really use the Trezor Suite or do you use Electrum and Metamask as wallets?

I mainly use my Model One and Safe 3 devices with Trezor Suite ^{[I've also tried using it with Electrum, but only for testing purposes]}.

I only use the BIP39 standard, I ignore the existence of SLIP-39 shamir backup. I think it's wrong for them to push SLIP39 since, in addition to not being the industry standard, the user will have more work when restoring. Very few wallets support SLIP39.

If SLIP39 were backwards compatible with BIP39, I would recommend using it.

I use Trezor Suite or with Sparrow, Electrum.

[dkbit98]

This is not a mistake.
With SLIP39 you can have much better security of your keys, by secure splitting in multiple parts.
Other hardware and software wallets already support Slip39 and more of them will follow in future:

This is the list of bitcoin wallets currently supporting SLIP39:

• Electrum
• Sparrow wallet
• Blue wallet ^mobile
• Trezor ^HW
• Keystone ^HW

There is even a tool for converting SLIP39 into BIP39 and I wrote more about it in this topic:

I use Electrum for handling the wallet most of the time.
Trezor suite I use only for updates/installs.

However, on Android I may have to use Trezor Suite Lite now and then, since there I simply don't have enough options... (and afaik none of them can handle coin control).
