My new TREZOR

[Mike Hearn]

I received a beta TREZOR from SatoshiLabs. I'll be ensuring that the HD wallets support in bitcoinj is compatible with it, as a first step to allowing any bitcoinj based wallet app to use the device.

The device works perfectly and was very easy to set up. It is extremely light and comes with a way to attach it to a keyring, though I think for now I'll keep it at home. As part of setting up the device, it generates a new random seed and you write down the 12 words into a booklet which comes with the device: that's your paper wallet. To make a payment you use the web app, and it asks you to confirm first the destination and then the amount+fee (so you press twice). The instructions are clear and simple at all times, and the performance is excellent - there are no long waits or other interruptions.

The web software still has a couple of minor bugs, but nothing that interferes with usage.

Version 1 of the system does  not yet support BIP 70, so when you see a confirmation, it's for the raw Bitcoin address. Future releases are planned to support BIP 70 so you will see a more useful and harder to tamper with confirmation message that includes the name of who you are paying.

I was one of the first supporters of the TREZOR project and I'm happy to report that together stick, slush, Alina and the others at SatoshiLabs have actually exceeded my expectations I'm very much looking forward to the device shipping.

Looks very nice and glad to hear you're pleased with it. Look forward to ours arriving as well.

Ooh. Pretty! Does it come with a rubber case?

[xeroc]

Very sweet! congrats

Nice to finally see a hardware wallet!
Does anyone know when it will be released to public and how much it will cost?

They were accepting preorders before for 1 BTC (I think back when 1 BTC = $100?)

Nice to see it in the flesh and thanks for the review Mike.

Just to tick all the boxes here, can you confirm that you have no other vested interests in TREZOR (shares in company, consultant agreements, endorsement incentives etc) that might bias your review? (Excepting of course being enthusiastic about the tech. generally.)

what if the battery died?

[Mike Hearn]

There is no battery. It's USB powered.

Just quoting this so Mike see it...

Kinda fishy you got one so early on, I think the core development team should really have been the first to handle it so they can add support and confirm that is follows the BIP 32 as spec'd by them. Would have been a nice independent review as well.

Yes, Trezor supports bip32 "as they spec'd", it passes all test vectors and it has been tested also with other bip32-compatible software (Bits of proof server) that it generates same bip32 trees. No need to ask bitcoin core devs...

Nice. Did you open the case already to
see what's inside?

Shouldn't this announcement have been made yesterday?

man, that device looks beautiful...  i could imagine that such a device could gain popular traction not only because it´s bitcoin but because it is stylish...

[Mowcore]

The display looks much better than I first imagined it to look like!. Good work Slush & Co.

I would have ordered one if it was affordable. But a price of $480 means almost 10% of my BTC holdings. I would wait for some more time till the price is reduced. Or may be I will be able to obtain an used device in the near future.
