Sorry, I'm not interested with this stuff.

Hi guys,
Can I sign&verify btc transaction on trezor? i connected my trezor but i didn't find that option on btc wallet
Can I sign&verify btc transaction on trezor? i connected my trezor but i didn't find that option on btc wallet
Bitcoin Core has not established a protocol to sign from segwit addresses. The default wallet for trezor only uses segwit addresses. I believe that you should have the option to use the legacy wallet and be able to sign a message from there.
My literal reading of the question "Can I sign&verify btc transaction on trezor" is that he is asking if the Trezor signs transactions to which the answer it "that is the main purpose of the device, so yes"
Reading between the line perhaps, as you assumed, he is really asking "Can I sign&verify messages on trezor" to which the answer for legacy Bitcoin addresses is "of course - it has always been able to do this"
AND the answer for SegWit addresses is "Trezor is one of the few wallets that can and does offer a signature algorithm for SegWit addresses - full disclosure: the SegWit signature algorithm implemented on the Trezor is not a standard yet."
Finally to answer his question "i connected my trezor but i didn't find that option on btc wallet" I would need to connect one of my Trezors and find it but I am currently at work so I will do that when I get home or, someone else can answer that part.
The real answer to whether you can currently use a trezor to sign a message with a Segwit address is found here. https://blog.trezor.io/rolling-out-trezor-wallet-segwit-segregated-witness-5700269debc5

Why can’t I sign or verify a message?
While the TREZOR firmware supports signing with SegWit addresses, there are currently no other wallets or services which support the signing feature. Also, there is no agreed standard yet, therefore the compatibility of signature and verification processes cannot be guaranteed. These functions were temporarily removed from TREZOR Wallet.

Don't know how smart that can be.
It is electronic device. Any electronic device can be broken.
So why not just on USB drive?
It's almost the same, but without extra protection.
But as idea is safe and "in your pocket", then I chose USB.
The trezor digitally signs the transaction on the device. You can not do this with just a usb drive. You would have to import the private key onto a machine like a computer that is not designed with this type of security in mind. The trezor has an extremely narrow interface which only recognizes a hand full of very specific and limited function calls.
As far as every electronic device can be broken. This is false. It sounds like something you would hear in a hollywood movie about hackers. Any given device probably has some sort of vulnerability but not necessarily.
what about badUSB?

Thanks to all,wrote it on a paper with trezor 
Can i write my seed words wnen i offline or no need to worry ?
do not type the seed into any device. write it with a pen on paper. several times. store at different locations and NOT where your trezor is stored.
Note that the seed itself is sufficient to steal all your bitcoins. Storing it away from trezor does not help.
what i wrote was meant to prevent the situation that a fire/flood destroys a house/apartment/room - if the trezor and the seed get destroyed there is no recovery possible.
edit: i recall a user who had placed his hw wallet on a desktop computer that cought fire. the poor guy had kept the seeds on paper on top of that same computer. all was gone.

I'm a bit suspicious, I've had plenty of little electronic gadgets take a shit over the years for no real reason
I've been using my trezor since right after release and it has held up really well with zero signs of wear of any kind. It even feels like a really high quality product when you hold it in your hand and manipulate it. So A+ from me.
*edit* I should mention though that I don't unplug and replug it from the usb port on the trezor. I leave a short usb cord attached at all times because I know how those ports tend to wear out on every device. So I can not attest to that particular aspect.
Can I use it for a cold bitcoin wallet? What is the principle of cryptography used in this device? How with protection against hacking?
so, these things really work?

also, what about badusb? https://www.wired.com/2014/10/code-published-for-unfixable-usb-attack/

Would someone please write up a BIP for the SegWit signature algorithm implemented in Trezor and discussed here:
https://github.com/trezor/trezor-mcu/issues/169
So that we can kick start the process of having this become the industry standard algorithm for signatures based on SegWit addresses.
I am sorry but I do not have the time to write it up right now.
Thanks!

You are probably right from the security point of view...
Thats my second options.
First option would be to use seed key and recover that on my TREZOR, then i dont need to create another address.
I am not sure if that is possible with combination Trezor/Exodus ?
So you are asking if you can take the seed words from your Exodus and enter them into your Trezor and recreate your accounts on the Trezor.First option would be to use seed key and recover that on my TREZOR, then i dont need to create another address.
I am not sure if that is possible with combination Trezor/Exodus ?
I do not know the answer to that question but I do know that is not a secure method of transfer.
Good luck.
