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.

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

Been playing around with the newest greenaddress this morning and it works (version 0.0.66, downloaded directly from github).

After initializing with greenaddress, the hw1 then works fine in greenbits.

I then tried to log in with myLedger and it worked, but i think it uses a different address path.

Some questions: are the greenaddress and myLedger accounts/ addresses using the same seed? So that if I wiped then restored the seed, I could restore my addresses and balances on both myLedger and green address? And is the security card used with myLedger separate from the seed and not reset when entering PIN 3 times?

I was unable to get btchip support working.

Sorry for so many questions, by do you mean greenaddress in chrome store?

Do you mean greenaddress and greenbits? And do you mean with the next update of the android and chrome apps or update of HW1 firmware?

Sounds good. On the software side the only app I can use is myLedger. I really hope you guys get an android based client working over OTG cable. So far greenbits hasn't worked and greenaddress hasn't worked and I can't get electrum setup with btchip support.


My main use case is for cold storage so I don't have to keep making paper wallets. Being able to withdraw from that without a computer would still be nice though.

This more or less worked. Thanks.

I'll still email support, but basically greenaddress chrome app doesn't see my hw1 as being connected to have a seed written to it or to create its own entropy.

I then did a firmware upgrade.

I then tried greenaddress again and it didn't work. Since hw1 and ledger are identical after the latest firmware, I tried myledger. It sees the device then later says it's not supported. Support site/faq says this means it was flashed without a "security card" (which I believe is a ledger-specific thing). I tried reflashing with a security card seed but it didn't help.

All was done initially on Linux with chromium (yes I added the udev rules). I then tried everything in Windows 8 with chrome and got the same result.

@btchip I got an hw1 in the mail. Tried everything and can't get it to work. You prefer troubleshooting here or by email or irc? (or are you even the right person to contact?)

Does hw1/ledger/greenaddress work on chromium instead of chrome? Wasn't sure if this is a btchip question or a greenaddress question...

Sounds great. Being able to easily load up xpub into mycelium, the ledger companion app, or btcrecieve (which the trezor folks have rebranded into the "my trezor lite" app) would make it much easier to receive funds to new addresses in the hd wallet without needing the device connected. Definitely something I would think most users would be interested in, especially if btchip-based devices are being used for cold storage and kept in a safe, not readily accessible place.

Thanks very much for the reply. One more question: is it possible to export xpub from the device so you can generate receiving addresses without having the device plugged in? What I mean is using it with mycelium or BTCRecieve for watch only but also for generating receiving addresses.

Can I use greenbits on android to do all that is needed in wallet mode with the hw-1? I mean from initialization through usage? Or do I need to use a computer for some steps?

Also, does hw-1 use it's own rng? Or does it use that of the host? Or some combination? Is it possible to add your own salt?

Also is the 2fa via usb keyboard emulation required for every transaction or is that optional?

Is hw-1 basically the same as ledger with a different form factor? Or are there usability differences?

(sorry if these are answered elsewhere in this thread... I read back several pages and didn't see anything conclusive).

Hi Kano and friends.

I periodically check to see if kano.is pool is working with my AMTube miner because I'd love to move over from another pool.

It's still not working without proxy. I know it's not high on the priority list but I wanted to just pass that along.

Thought maybe you weren't using it anymore, in which case it would make sense.

If you'll sell me the tube for .3 BTC shipped its a deal.

I'm interested in buying a single working ASICMiner Tube HASHING board.  Offering .3 BTC but that price is negotiable. Will want to use escrow until I can verify the board is in working condition and runs stable for at least 24 hrs.

Note: I'm ONLY interested in the hashing board itself. I don't need the heatsink.

Please reply here or PM me.

Does anyone have a tube just sitting around gathering dust? I'm interested in getting one more hash board from a tube. Currently have 2 tubes but only 7 hash boards (sent one for rma, but that process is completely stalled). I'm not willing to pay much, but maybe we can work something out and I can help de-clutter your house. Please pm me if interested.
