really i don't want to use old seed, you're right. I want to create a new seed from ledger/trezor and make a transaction from my electrum wallet.
But i want to do this for each electrum wallet i have.
What you could do with the Trezor/Ledger is use different passphrases to generate a different BTC wallet for each Electrum wallet you have. The passphrase effectively acts like a "25th word" for your seed... and allows you to generate completely different wallets based off the same seed.

some references:
https://ledger.zendesk.com/hc/en-us/articles/115005214529-Advanced-Passphrase-options
https://blog.trezor.io/hide-your-trezor-wallets-with-multiple-passphrases-f2e0834026eb


Alternatively, you can setup multiple "Accounts" within your Trezor/Ledger wallets... and each account could act like your separate Electrum wallets. Each account has separate addresses/coins etc... but are all able to be recovered from the one seed.

thanks for your answer.

I'm not sure that i have understood correctly what the links say.

Let's make an example.
I have an electrum wallet with 1 btc and its own seed and Passphrase , and an other electrum wallet whit 2 btc with its own seed and Passphrase .

I buy a trezor. I create a new btc seed for my trezor.

I send my 3 btc to trezor, so, all of these btc have now only a seed and no Passphrase.

Then i enable Passphrase encryption on my trezor.

Then i can create two different Passphrase and send 1 btc to my first Passphrase wallet and 2 btc to my second Passphrase wallet.

So, after that, i have to wallet with two different amount on them.

If i want to import my trezor's seed on a new electrum wallet, what happen? I will see a wallet with 3 btc, or what else? I don't understand this part Sad

An other question: is it more safe use a Passphrase on trezor?

I would vary the steps you are planning on taking.  For privacy I would not transfer ALL my BTC into the Trezor wallet without the password.  When you then move the BTC from that original wallet to the other two passphrase protected wallets you are creating a "trail" that can easily now link the other two  wallets to the original.  For privacy it would be better to move only 1 BTC (using your example amounts from your post) to the non-passphrase wallet.  Now you transfer the other 2 BTC to the remaining wallets directly from Electrum or wherever.  This way there is NO connection between those wallets at all in the blockchain.  On a Trezor when you use passphrases those wallets generated all have totally different MPK's and addresses.  If you handle your transactions properly you can keep them separate from view in the blockchain as well.  In my case when I did what you are doing I ran a commercial mixer between my Electrum and the Trezor wallet destination.  I wanted to make sure even the original Electrum wallet link was severed from my personal Trezor wallets.  You may not care about this, but I wanted to explain this to you and other readers.  During Trezor wallet creation this is the time to make it "alone" in the blockchain without reference to where the coins on it came from.  Just my take on this.

edit:  the passphrase issue is one you have to consider.  If you go the passphrase route (I do but that's just me) and ever need to restore because your Trezor breaks or is stolen you will need BOTH the 24 word SEED and all the passphrases.  If you forget a passphrase your coins are lost forever so pause and consider securing the passphrase if you go this route.  BTW - this is much better than a 25th word.  I hear that all the time but its not quite true.  I could hand you my 24 word SEED list and tell you to have fun finding my wallets.  You will not simply try adding a 25 th word and ever solve the math needed to build my passphrase generated wallets.

From the Trezor blog:

Quote
In other words, your passphrase acts like a “25th seed word,” meaning your entire wallet — private and public keys, addresses — are generated from your 24 seed words and your passphrase — from all 25.

Chainanalysis companies have been able to trace bitcoin transactions past mixers for over a year. Don't count on a mixer for privacy. If you need to recover your Trezor seed and passphrase to a different wallet see the guide on Trezor docs. This compromises your seed and passphase so you are better off just restoring to a spare Trezor.

You should just do this... create the passphrases FIRST... then transfer 1 btc from "ElectrumWallet1" to "TrezorPassphraseWallet1"... and 2 btc from "ElectrumWallet2" to "TrezorPassphraseWallet2"... or, as I stated earlier, you can simply create multiple accounts in Trezor. Refer: https://blog.trezor.io/wallet-accounts-and-addresses-bdfa6b66b037 - The section on "Accounts". You can have up to 10 BTC "accounts" in your wallet... it's a bit like having a checking account and a savings account. The accounts are "separate"... ie. you cannot create a transaction that includes coins from Account#0 with coins from Account#1 in the same transaction... but all the accounts are generated from the same seed/passphrase.

To import the seed into a new Electrum wallet, you would enter the seed, click "options", select "BIP39 seed" and "Extend this seed with custom words"... you'd put your seed in, then on the next screen, you're prompted for the "extra words"... this is your "passphrase".

So you would need to create 2 new Electrum wallets... one for each "passphrase"...


If you use the "account" method, you'd still need to create 2 new Electrum wallets when restoring to Electrum, but instead of having passphrases, you'd simply change the Derivation Path (m/44'/0'/1'... m/44'/0'/2' etc).



Quote

I'm not sure what you mean here? Using a passphrase means you can effectively "hide" your actual wallet... someone could have your 24 word seed, but without your passphrase they will never find your actual wallet... bruteforcing a "strong" password (10+ alphanumerics+symbols) is impractical for current computers (length of time required measured in years etc)... so if your piece of paper with your seed words gets stolen, and you've used a passphrase, you have plenty of time to move your coins before the thief can access them. Without a passphrase, as soon as they have your seed, they effectively own your coins Tongue

I have chosen Ledger Nano S. However, it seems that each of them is good. So it is better to have any, than to live your funds unprotected.

thanks for your answer.

If i've understood well, the problem is this my sentence "I send my 3 btc to trezor, so, all of these btc have now only a seed and no Passphrase.".

So what i have to do is:
-send my btc from my first electrum wallet to a non-passphrase wallet trezor wallet
-then do the same thing for my second electrum wallet.

Is it correct?

mmmm, recover my trezor seed compromises it because there can be a possibly infection of my pc? Or for what other reasons?

My trezor seed will be ok if i simply import it on electrum with "import hardware wallet" procedure? I know that it will import only the public keys..

Thanks a lot!

Because it'll help protect your privacy and also save you some transaction fees... if you go:

- Electrum1 -> Trezor
- Electrum2 -> Trezor
- Trezor -> TrezorPassphrase1
- Trezor -> TrezorPassphrase2

You have effectively linked ALL your BTC together... plus 2 extra transaction fees... Tongue


Much better to do:
- Electrum1 -> TrezorPassphrase1
- Electrum2 -> TrezorPassphrase2

Your BTC remain "unlinked"... and you only do two transactions instead of 4.

If you don't care about privacy you can send them all to same Trezor wallet first if you want and then split into two wallets... And if you don't want to keep your BTC separated, there is no need to create multiple Trezor wallets or Accounts.


Quote

You will create the "watching only" wallet for whatever passphrase you used to unlock the wallet when you create the Electrum wallet.

So, if you connect to Electrum and "import hardware wallet"... and use Passphrase2, you will get TrezorPassphrase2 wallet imported to Electrum... if you use passphrase1, you will get TrezorPassphrase1 wallet imported to Electrum etc.

To switch from one wallet to another in Electrum, you need to disconnect/reconnect the Trezor and unlock with the passphrase for the wallet you want to view.

now i know what to do.

When you talk about "watching only" wallet you mean that without trezor i can't made transaction, or, in any case i can't made transaction with electrum?

When you talk about "watching only" wallet you mean that without trezor i can't made transaction, or, in any case i can't made transaction with electrum?
Correct... the wallet you create using the "use hardware device" option will create a "watching only" wallet as the Trezor will only present the "xpub" master public key to Electrum. This means you will be unable to spend without the Trezor attached.

To spend without the Trezor you would need to create a "standard wallet" by importing the Trezor 24 word seed mnemonic.

I'm sorry to up this thread again, but there is something i don't understand: if i've a trezor wallet with passphrase, and someone stole my seed, why he can't just simple import that seed on electrum and steal my btc?

It's because my trezor's passphare works as the electrum's passphrase?

A passphrase have no equivalent in Electrum (check the post beloiw, my bad). Trezor give you 24 words, consider that passphrase as the 25 word that you can create yourself (can be anything) so even If someone have access to your seed, he can't do anything.

Yes, it does...


This option (available when you click the "Options" button on the seed display screen) allows you to effectively add a Passphrase to your Electrum seed. It is NOT the same thing as a wallet password (which is used to encrypt the data in the wallet file)

not much. it certainly won't come up with your addresses if you don't have the 25th word. the 25th word unlocks all the other seed words. without it they're scrambled.

think of it like a seed password, not a wallet password.

Exactly what happens when you load up your Trezor wallet with no passphrase... You get a completely different wallet generated.

The Trezor folks have a really good explanation about seeds and passphrases (and PINs) here: https://blog.trezor.io/seed-pin-passphrase-e15d14a0b546

This is why they talk about passphrases being a "25th word"... Like the other 24 words, it is absolutely 100% required to recreate your wallet if you use it to generate the wallet...

And like the other 24 words, if it is spelled incorrectly or missed out, you will be unable to recreate your original wallet.

thank you so much, now it's clear! So, it's just important as the other words of the seed and i have to use it when i create a new wallet on electrum with a seed..

thank you too, European Central Bank

On amazon, it seems the ratings are a lot higher for the trezor vs nano ledger s.  Is there a reason for that?  The other thing i noticed is the price of the trezor has dropped a lot to where price is similar to nano ledger.  Is there reason why?  Heard lot of negative reviews of ppl buying ledger s through amazon saying its a fake or compromised one.  Is there a reason there hasn't been cases of this with the trezor?


So basically if you buy a nano ledger s, make sure you buy it from manufacturer.  But with trezor, it doesn't matter?  I haven't heard of cases where a compromised trezor was bought.  Anyone read about that?


Does anyone know if nano ledger s you could put a 25th word yourself?  So with trezor and the 25th word, it generates you 24 word seed.  Then you make your own 25th word which could be any word you want, no matter how many letters?  So if someone were to figure out your 24 word seed on trezor as it got exposed somehow, does that mean its basically impossible for them to access your trezor if you put a 25th word?  Like imagine your 25th word was something like
hewenttogetsomedrinksagain?

I've ordered Ledger from "LedgerWallet" seller on Amazon.de, it's official account of Ledger France and so far (it doesn't arrived yet) I'm very dissapointed, as Ledger wrote me, that they don't raise VAT-EU invoice.
So, I'm waiting for another reply from Ledger itself and Amazon and I will probably return it and buy Trezor.
