[NOW AVAILABLE] BTChip / Ledger HW1 : Bitcoin Hardware Wallet in a USB smartcard

[Mitchell]

Yes. It is supported by GreenAddress today - on https://play.google.com/store/apps/details?id=it.greenaddress.cordova (Play Store) or https://f-droid.org/repository/browse/?fdid=it.greenaddress.cordova (F-Droid)

That is awesome! My phone has OTG support, but I never used it, because I didn't need it. Now I have a purpose for it.

yeah, most recent Androids should support OTG

Yeah, they should. I didn't even know my phone had it until I used needed to connect one of my USB Storage keys to it. Also, please ship faster. You are making me way to excited for this little gadget.

[btchip]

Sorry, backlog will be done today

this attracts me but actually Its uses are not clear
I understand this stores the private key,but when using it,is it neccessary that the private key is stored anywhere? I mean,in the pc that you use or online.
can you erase the wallet and create new wallet? Can you use more this store more than one private key at the same time?

it's a Hierarachical Deterministic wallet - it derives an "infinity" of keys based from a seed. The whole point is that any private key never leaves the device. The seed leaves the device at one point to let you backup it in case you lose it, then it can never be accessed.

So the seed is store anywhere else? Like computer or online server? Or only in the key?

Looks great.

I noticed that you charged 20% VAT even though I'm outside of the EU. Is this correct?

Yes, it's a personal sale (unless you're a business, in which case you shouldn't order here according to the Terms & Conditions that nobody is reading anyway  ), so it's fine to apply the VAT policy of the local country up to a given volume (usually in the 100k€ range, so we're not there yet in two days, maybe after a few more days)

the seed (or rather the first derivation of the seed) is stored into the card and nowhere else after it is displayed the first time.

I see.  It is my understanding that exported goods are exempt from VAT.

Great project! Looking forward about it! I live in India. Can I use standard shipping? Is there any way to import private key? I mostly use vanity address, so it would help me.

  ~~MZ~~

Thanks ! You can always try standard shipping, absolutely no warranties as I've never tried a standard delivery to India

You cannot import a private key in regular wallet mode to avoid losing keys, but you can play with it in developer mode if you want (no wallet is supporting this mode for the time being though) - we might support sweeping a few keys in a future release if we get enough code space to add that feature.

Can you tell me ETA of the shipment? I just want to enter the address according to it.

According to french postal service, 1 week to deliver to India. So this is better than BFL, but with absolutely no commitment.

(if you already ordered, then PM me the reference and I can tell you if it was shipped on our side - all orders passed before the 12th were shipped)

it would be nice to be able to buy a card with bitcoin on it at the local stores

you already have some tested ways to buy a prepaid HW.1 card which are described in the specification - either remotely, by locking the card to a PIN before it's sent (see 'forward setup' in the setup command), or locally, by splitting the seed in two parts to make sure the merchant is honest (see 'point of sale' in the setup command)

buying a prepaid card immediately available in a store is a bit more complex, because you have many parties to protect against, but it's quite possible to design a custom version for a specific vendor scheme.

when is expected to come out an app out of chrome working with btchip?
i think electrum is expected soon

is there any way out of btchip to restore the btchip seed?

It's done already, just not released yet, but it works if you get it from github.

You get an option to read the seed right after it's generated, then you can setup the card (or another card) with a seed you provide yourself.

I mean,imagine I don't have any card and I want to restore the seed,what can I do?

[btchip]

you can use it with any software supporting deterministic wallets and the right derivation path (if you're using GreenAddress or Electrum, you can just restore the seed into a software wallet or another card)

So it just would be to copy the hw1 seed to a already existing electrum wallet when creating one,isn't is?

[Mitchell]

I have received my HW.1. I'm installing the drivers as we speak, let's hope this works

yes, with some minimal manual work (HW.1 outputs an hexadecimal seed that you'll need to convert to a mnemonic)

Good  sorry the start page is not ready yet, I'm waiting for catchy videos, but GreenAddress setup should be straightforward - in any case don't hesitate to ask around if you're stuck.

First of all, redirect http://start.hardwarewallet.com to the https one. I got a nice error page because I visited the http one

Also, I have troubles with keeping the thing inside my USB port... It keeps falling out/losing the connection because it moved. It's not thick enough to stay in..
