HW wallets - z-transactions

Hi guys!
Any news/update from ECC or ZFnd about this topic?
I am always waiting for good news… and we’re in 2020 now!
… and still we have no support for Z-transactions on a hardware wallet.

Thanks @rex4539 !!
A lot of time to wait for (September 2020 for full integration in Ledger Live, if schedules are respected), but at least someone has started working on it!!

Thanks!

Hopefully we can be faster… but it is not easy to get all the pieces working in such a small device / memory space.

With respect to timeline… We just closed milestone 1.

Twitter - Zondax Milestone 1

Our progress report can be found here:

Zondax Milestone 1 - Progress Report

Something to clarify, we are doing the app itself… C/Rust and some integration libraries that can be used by anyone…

We are (at least for now) integrating in to Ledger Live UI. We are looking at that… but the real challenge has always been the device itself. not JS-based wallets like Ledger Live.

@jleni,
thank you so much for the update!

I know that your job is difficult… and you and your team are doing a great job!!
I’m pretty sure that your work will increase ZEC adoption by at least an order of magnitude.
Storing ZEC on a hardware wallet is the key to be safe. Having ZECs stored through shielded transactions is fundamental to spread ZEC adoption… otherwise it lacks a great part of privacy.

Keep us updated on the development, please!

Cant wait to see Z addresses on HW wallets. Wonder how far out we are talking here… a month or two? more? From what I understand bluetooth wont be possible with the Nano X/ not sure why…

This would be a great step forward!

Take into account that Nano X uses BLE so desktop integration is not a typical use case from Ledger’s point of view. We are not considering bluetooth part of the scope. We could do that as a follow up, we don’t expect bluetooth in Nano X to be too hard… it just needs a fair amount of work and testing to do proper mobile integration.

About timeline, our grant has already a delivery schedule. It is possible that we can be a bit faster, though.
