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

[btchip]

Good to know. So it won't matter if I use greenaddress, myLedger, or the chip itself to generate the entropy and seed?

yes, same thing, even if you use some external API, you just need to make sure to include the feature NO_2FA_P2SH to be compatible with GreenAddress/GreenBits.

So I've been testing the HW1 with myLedger, greenaddress, and greenbits. So far I'm very happy with it. My only real sore point is not being able to generate receiving address without the device connected and unlocked. There needs to be an easy way to do this. Maybe integrating it into the Ledger 2FA app or at the very least a simple way to export xpub.

At the very least a simple way to export xpub.

you will be able to do that soon with the high level API - https://github.com/LedgerHQ/ledger-wallet-api and we also plan to add it in the Chrome app later

Cool. It's not a must have for me personally at this moment, but it will certainly make things easier.

Now officially supported with coinkite multisig.

You can now purchase HW.1 directly from the Ledger Wallet shop

Sounds great!

A 15 eur device will be far more appealing to new/novice Bitcoin users I'd say

yes, it has been hiding in plain sight for too long I guess

Is there any way to get a security card for an original HW card so that it can be used with the ledger wallet chrome app?

You should be able to create one in the firmware update process.

Yes, there's a link to do that at https://fup.hardwarewallet.com/buildKeycard.html

I've bought a couple of HW1, both with the old firmware. I've tried to update one to the latest version with success (througt the fup.hardwarewallet.com tool). I've tried to initialize it, but now is stuck after the generation of the seed, in the part when i should unplug it and plug with an open text editor to backup my seed. Basically everytime that i try to plug in this HW1 it's recognized as keyboard, but it does not output the seed, or at least return in the standard mode :/

[btchip]

Can you describe very precisely all steps you followed to end up with that and your system configuration ? (on Ledger support mail preferably). I've been tracking this one down and unable to reproduce it yet.

Thanks

Successfull firmware update > Setup with the internal seed generator > Backup the seed > Stuck

Can i also ask a good APDU tool to communicate with the btchip? (for low level tweaking)

[btchip]

With which software ? On which OS ?

on https://github.com/LedgerHQ any API should do - the C version being the most documented

Electrum + ubuntu 15.04

Now i've a bricked btchip and one that is working flawlessy

But my major concern is this (also posted on github):

I've set my btchip in relaxed wallet mode, and now i should be able to sign transactions with how many outputs i want. But when i try to load a CSV range of address + amounts with the dedicated feature in electrum, the button "Sign" just does not appear.

There is an already aviable tool that allows a complete use of the relaxed/developer mode?

I was able to unbrick a HW-1 with a firmware downgrade

https://fupbeta.hardwarewallet.com

Followed by a firmware upgrade on OSX using ledger chrome wallet

Running the Ledger Chrome Wallet upgrade on Odroid Arm Ubuntu 14.04 fails every time.

Still waiting to hear back from the Ledger Chrome Wallet devs.....

I'll re-ping. Sorry, it's a bit difficult to get hold of people in France in May (about 2-3 bank holidays per week all month)

[kalgecin]

Hi can I use the same wallet I use for my other ledger products on this easily?
