Official Shielded Support for Zcash In Ledger HW Wallet

[zerodartz]

thanks for updates. one day it will release im sure.

[Blazin8888]

Thank you for the update and your hard work. Getting shielded hardware wallet support is a critical piece that will empower Zcash users. Once we have this and DEX support (Maya Protocol), it will change everything.

Deliverable 2.1

Zcash Ledger app with Sapling support including the necessary fixes resulting from the audit

@Dodger

We have just completed the app submission process.

@ainhoa-zondax

Engagement in Collaborative Efforts we have been active in collaborating with other teams, such as Zingo, to facilitate the integration of this new app. We have also recently spoken to ECC and are really looking forward to have integration of Ledger wallet support in their upcoming wallet, Zashi . We are committed to offering our support and expertise to address any queries that may emerge during this integration process.

@ainhoa-zondax

We were in the final stages of release, but during our internal functional review, we identified a few issues that have since been addressed.

@ainhoa-zondax

I hope I can provide you with a concrete timeline in the next weeks.

@joshs @zancas What’s the hold up? This release won’t even have UA’s nor Orchard if I’m reading this correctly. Thank you for any insight.

[silentZcollector]

exactly, it’s a shame! and we all should feel ashamed for it!

there are a few grants that always deliver, but besides that everyone is taking it easy and seems to not care as much as they should.

guys, i am waiting for shielded transactions on my ledger for years.

[zerodartz]

funny is ledger and zondax are the ones who have been responsible for the delay

except Hanh, who made it shielded possible by sideloading on Nano S, but they didnt like his Ledger app to integrate into official ledger app

[hanh]

There are no app on the Ledger Live store.
Using sideloading, everything has been supported for more than a year.

[ywalletfan]

but sideloading only works with ledger nano s plus, right… not Ledger Nano X and not the brand new Ledger Stax. Also, last time I checked, ledger button to import wallet was not available in the desktop app (has it been readded since?) and the ledger page from https://ywallet.app/ disappeared.

[hanh]

I removed it because they said they were developing a version for the Ledge Live Store and were going to release it “soon.” The code is still there but disabled.

Sideloading works for NanoS, S+ and Stax.

[ainhoa-zondax]

We have implemented the app for all existing devices and are committed to this project, working to resolve all obstacles to ensure its official release on the Ledger Live store.

There have been delays, primarily to the difficulties on the integration with wallets and more recently with crashes on Nano X devices.

Currently, we have a functional copy of the ZEC wallet that is compatible with this app, and Ledger is using it for testing. Some delays on their end have been related to the anticipated release of the Stax device, which is now finally being delivered.

We have also collaborated with Zingo to assist with the app integration, though we have no control over their timeline and priorities. Additionally, we have engaged with the Zashi team, who have shown interest in making their app compatible with Ledger in the future.

We have published guidelines to facilitate wallet integration with our app, but we have no control over the timelines of these integrations.

While it’s true that the initial app won’t support UA and Orchard this is something that we would like to support once the initial app is published.

I share your frustration regarding the project’s delays and assure you that our team is taking this very seriously.

[zancas]

It’s a priority… we’ve had to delay to adapt to the ZIP317/ZIP320 work that was not in our original roadmap. Barring more surprises we’ll be actively working on it soon.

@HIROSHIMAH

every other project in the crypto space gets its app implemented in ledger live faster than zcash

I share your frustration. But, you have to realize that this is because Zcash is very unique, and very difficult to work with compared to all of the transparent ledger, cookie-cutter projects. The magnitude of difference might be likened to riding your bike around the block versus landing a live zebra on mars. So, we should all learn some patience and grace as we work towards enormously difficult goals through uncharted waters in adverse conditions.

[zkcroc]

This has one of the most frustrating let downs for me personally. It has been almost at the finish line several times the last few years but always just out of reach.

Ledger support is a fundamental first step of adoption and self custody for the crypto masses, and has been a major disappointment that it had been such a shamozzle

Im eagerly looking forward to Zondax finally getting the job done

[zkcroc]

Thats true, but for many people, myself included it is low hanging fruit easy solution for multi coin crypto storage that at least has the perception of being more secure than a mobile or desktop wallet.

No shielded ledger support has been a big barrier for getting coins in the shielded pool, imo

[skyl]

Zashi uses mobile SDK. Just install Ywallet or Zingo for Desktop.

[zkPete]

do I dare to ask for an update?

[dismad]

@Dodger

This work will deliver a new embedded Ledger app with support for transparent and Sapling shielded transactions. We hope that this new embedded app will allow Ledger users whose funds are currently “stuck” to unlock their funds.

The next step once that app has been accepted and published by Ledger will be to look at updating Ledger Live to support Sapling shielded transactions (we’re referring to this work as phase 1a).

@ainhoa-zondax

Currently, we have a functional copy of the ZEC wallet that is compatible with this app, and Ledger is using it for testing. Some delays on their end have been related to the anticipated release of the Stax device, which is now finally being delivered.

Can you shed any light on the delays and how long this will take? Month after month and zero details

[ainhoa-zondax]

Hi @zkPete @dismad

Currently, we’re investigating some issues related to spends/incorrect balances between the app and the wallet. A lot of frustration is building up due to these ongoing problems and unexpected delays, but our team is committed to resolving them.

We have been struggling with some incompatibilities between our Ledger app and lib(ledger-zcash-rs) and the lite-cli crate.

• zip32 derivation issues: this is already fixed and we are now using official test vectors
• nullifier calculation was ignoring the derivation path and funds were not considered spent in the CLI

We have been looking at a reference implementation for example, Zcash node code to re-use some of their tests, and compare the result with our unit-tests ensuring we get to the same values mentioned above when using the same seed.

The main issue is that this is complex rust code that has changed a lot and we are pretty behind… upgrading can be a huge challenge.

In the process, we have made several improvements to the app to enhance performance and clean up the code.

We have created an internal task force and allocated our best resources to tackle these challenges.

Although we haven’t heard back recently from other wallets making progress on the integration, we remain open and willing to assist them in achieving compatibility with the new Ledger app. A desktop or CLI integration compatible with the Ledger app is a requirement for the release.

I will do my best to keep the community updated more frequently on our progress and timelines.

[zancas]

Ledger Integration is a high priority. We intend to release ZIP317 within the week. ZIP320 is our next priority beyond that, and ledger integration to follow.

[zkPete]

Hi @zancas - Did ZIP317 get released? Just checking what the timeline is for ZIP320?

Thanks

[zerodartz]

latest zingo seems to have zip317 integrated as posted here: Zingo! Onward - #55 by zancas
