Electrum seed on Trezor

[Sidney986]

I,m thinking of buying a trezor model one hardware wallet and would like to know if I can import my Bitcoin electrum wallet seed words and extended seed word rather than making a new wallet on the trezor.

Your seeds should always be generated on the hardware wallet and not exposed otherwise. Importing seeds that has been generated elsewhere basically gives you the security of the weakest link (ie. the device for which you've generated it in).

To answer your question, you can't. Electrum seeds are not compliant with BIP39 standards and thus cannot be imported into Trezor.

[Sidney986]

Thanks for quick response. 

Could seed words generated in trezor work with software wallets such as Blue wallet?

Seed words from Trezor will work in Electrum or other wallets that support BIP39 seed.
What ranochigo said is for 'Electrum seed' to Trezor, but it'll work vice versa (Trezor seed to Electrum) using the BIP39 option when importing seed phrase to Electrum.

[ranochigo]

Trezor uses a set of specific derivation paths. So long as your wallet supports BIP39 seeds and allows you to specify your own derivation path according to their standard; https://wiki.trezor.io/Standard_derivation_paths. Then you can import it into that wallet. Electrum allows their user to do so, not so sure about Blue wallet.

Yes, it will work. But why importing seed phrase generated on hardware wallet to online wallet, this makes the seed phrase to be less safe and less secure as it is online and can be accessed by hackers if your phone or computer is infected with malware. The best is to just make your seed phrase remain offline except you do not have another hardware with you and it is urgent to move your funds, then you can use Electrum as cold wallet if you have two devices, the other as watch only.

Electrum allows their user to do so, not so sure about Blue wallet.

You can import BIP39 seed on BlueWallet, BlueWallet is a BIP39 supported wallet, it will work as fine, it will automatically look up the derivation path that you have used for transaction before and the one funded with BTC, also you can manully click on derivation path that you want be it BIP44, BIP49 or BIP84 during the seed phrase importation. So it will definitely work as good for Trezor seed phrase.

also you can manully click on derivation path that you want be it BIP44, BIP49 or BIP84 during the seed phrase importation.

As far as I know, Bluewallet doesn't allow you to select the derivation path manually when importing a seed phrase.
In the case the seed phrase belongs to a non-funded wallet, it uses the path m/84'/0'/0' and there is no way to change it.

Bluewallet only allows you to select the script type (not the exact derivation path) manually when you generate a new seed.

Yes, but I specifically meant funded ones (it will lookup for the derivational path of the funded addresses). If not funded, the default derivation path is native segwit.

BlueWallet also generate native segwit address by default.

You seem to have a fundamental misunderstanding about what a hardware wallet does and how it protects your coins.

By using a Trezor to generate a seed phrase, your Trezor then derives private keys and addresses from that seed phrase. You can send bitcoin to those addresses, and they are very secure since the private keys to unlock and spend those coins are stored only within your Trezor and not in a less-secure software wallet, and are protected from being accessed by outside sources, the internet, malware, etc.

If you generate a seed phrase on a software wallet and import that seed phrase to your Trezor, then your private keys are now duplicated in two places - both on the initial software wallet and on your Trezor. Therefore, any coins you send to these addresses are only as safe as the initial software wallet you generated the seed phrase on. Importing a seed phrase in to a hardware wallet does not magically make it more secure. Similarly, if you take a seed phrase securely generated on your Trezor and import that to a software wallet, then you have lost all the benefits of your Trezor and your seed phrase is only as secure as the software wallet. Think of it like having the password to your bank account written down a piece of paper inside a safe in your basement, but also written down on another piece of paper which you carry around in your pocket. The security of the paper in the safe is irrelevant, since your other piece of paper could be stolen at any time.

If you are planning to duplicate your seed phrase on to a software wallet, then there is literally no reason to use a Trezor or other hardware wallet.

BIP39 seed words from Trezor could probably work in Blue wallet, but you should NOT use any seed words from cold wallet to import them in hot wallets like Blue wallet, unless in case of some emergency moving of coins.
In the same way you should not import seed words from any hot wallet to hardware wallet because you are increasing the risk of losing your funds.
Point of hardware wallet is to keep seed words and device offline and not connected to internet.

I think he is trying to avoid broadcasting his transaction and thus transferring it to the wallet.

It is better for you to create a new (more secure) wallet using Trezor and enhance your privacy by using any method of coin mixing rather than trying to include it because it will not work (against the philosophy of buying a hardware wallet)

The point of protecting your money lies in how your wallet is generated. If it was generated in a dangerous way, including it to hardware wallet or any system will not improve security.

[Charles-Tim]

Or, maybe Sidney986 is looking for an easy way to be monitoring his bitcoin transaction, though, I do not see anything hard to operate hardware wallet but Trezor are used with software on computer and maybe he needs more easy access like on mobile.

You do not need to import your seed phrase on online wallet if that is what you want, you can just create a watch-only wallet on Electrum which can also be done on mobile Electrum for tracking your bitcoin transaction.

On Electrum click on Standard wallet -> Use a master key,  then paste in your master public key (not your private key). Master public key begin with xpub for legacy, ypub for nested segwit and zpub for native segwit.


Note that the purpose of this watch-only wallet is to track transaction, you can not use it to sign transaction. Which means if you lose your hardware wallet and its backup (seed phrase + (passphrase if included)), then your coin is lost forever.

[Sidney986]

Thanks for all the great replies.

I  normally sign transaction with electrum on a offline computer but it will not alway boot up and this process take longer to sign transactions.

I can now order a trezor in the knowledge the seed words will work in electrum offline should that method ever be needed again.

Thank you.


I like using electrum to sign air gapped transaction because I can verify my downloaded version of electrum with signatures.

Can trezor software updates be checked with signatures?

If I am not wrong the actual work of hardware wallet is to keep the private keys safe from the device where we are connecting to make the transaction so the hardware wallet itself will act as an airgapped device and its more convenient than using the airgapped device and another one to broadcast the signed transaction.

[o_e_l_e_o]

Can trezor software updates be checked with signatures?

Yes. The Trezor Suite software is open source and you can find the necessary keys and signatures on their main download page here: https://suite.trezor.io/. Obviously you should confirm the key from independent sources.

Also worth noting that you can use Electrum directly with your Trezor device, where your private keys remain secured on the Trezor but Electrum acts as an interface to manage your addresses and sign transactions.

The signature of a firmware means nothing if you don't trust Trezor because you're not independently verifying the code. The purpose of a signature is merely to verify that it is coming from a source that you're expecting. Assuming that your Trezor is not compromised (ie. not tampered with during shipping), then it will only accept signed firmware from the manufacturer.

I think he is trying to avoid broadcasting his transaction and thus transferring it to the wallet.

In that case, the more appropriate term is importing. Transferring suggests that a transaction took place and when we are talking about importing seeds, there are no transactions being made. He uses Electrum as a cold-storage client, so I don't think he is trying to avoid paying a few cents or a dollar to save on transaction fees. It's just a misunderstanding due to the difference between Electrum and BIP-39 seeds.

I  normally sign transaction with electrum on a offline computer but it will not alway boot up and this process take longer to sign transactions.

It takes longer, it's less user-friendly, but it's safer. The security of your coins should be the top priority. It's inconvenient if the offline computer isn't booting up properly. Why is that? Is it a hardware or software issue? Did you reformat the OS before you installed Electrum on it and created your offline wallet?

I always update my Trezors (ones and T's) using trezorctl command line.  Trezorctl automatically verifies the updates and it displays the confirmation in code directly on the desktop screen. Further; I use my Trezors with bitcoin-only firmware making me somewhat unusual here in this forum.  LOL!
