Official Shielded Support for Zcash In Ledger HW Wallet

I cant see it for some reason? Should Zcash Shielded be available for everyone?

[Autotunafish]

Yes its avaliable, I just checked.

[Autotunafish]

Screenshots?

[tokidoki]

Only some users have seen it? Perhaps, A/B testing from Ledger or it depends on Ledger Live version.

[Autotunafish]

Having to update Ledger Live is common but to find it, you go to ‘My Ledger’ on the left panel and then search.
Im not using anything special

Perhaps it is an unsupported device version? I have the Nano S +. Ywallet Ledger required that version for Orchard, Nano S for Sapling, others were not supported so may be a similar instance here.

[hanh]

to clarify, it is
nano s: T+S
nano s+: T+S+O

[hanh]

the zondax ledger app doesn’t support nano x.

[Autotunafish]

I suspected as much. There are many other cold wallet options, as far as the setup goes, but to have your stuff on a usb in particular, you could run a persistent live iso of Ubuntu with your Ywallet and boot into an offline session to perform the cold wallet signing (I’ll try this out). Obviously, like the Ledger, you still need to backup properly in case of errors. You could also run a normal, non-persistent live iso which requires importing the seed every time, more opsecky (of course it also requires installing the wallet so it would be best to flash the iso with the wallet already contained).
Used to be, flashing a live Persistent iso was a little tricky, but apparently, Rufus exposes an option to just create a persistent partition, right there when you flash the disk, so we’ll see (update: it works).

I like the s+, it is cheap and looks like crapdiscreet. Not gonna raise attention to it.

[zkPete]

I have the nano x, is the shielded app compatible with the Ledger Stax?

@hanh

I like the s+, it is cheap and looks like crapdiscreet.

I agree, looks like a cheap pendrive. Good design choice by ledger. Not sure if they did intend to do that though LOL

Dear Zcash community, we want to announce that Ledger has finally officially released the new Zcash Shielded Ledger App developed by zondax.

This new application can be found in Ledger Live under the name “zcash shielded”

The new app is currently supported by the following devices:

• Nano S
• Nano S Plus
• Flex
• Stax

We developed the application to be compatible with NanoX, however, despite the continuous efforts there is an ongoing issue on NanoX devices that persists. The device takes too long in calculating keys and this triggers a watchdog, we’re working with the Ledger firmware team to find a solution for this.

Currently the only desktop wallet that supports this new Ledger app is a fork of Zec wallet that we have adapted to be compatible with the new Ledger app. This can be found here . While we recognise that this is not ideal, we’re actively collaborating and providing support to other wallets that want to integrate HW support (zingo, zashi etc).

Please find here further information

Here is a tutorial on how to use this new application to unlock locked funds due to the previous Ledger application “zcash” not supporting shielded transactions.

Finally! This is a big deal for Zcash and its nice to finally get it over the line after YEARS even though there a few compromises…

As a minimum, it is huge for people to reclaim their locked coins

What is the chance to get the ledger X account to do an announcement??

[diamantipl]

Congratulations, when will the app be available on Ledger Live? because I can’t see

[nuttycom]

I read through the tutorial for unlocking locked funds. Could you explain a little more about what is happening in this step?

16. Note the App Crash: The app may close unexpectedly after initiating the transaction. Don’t worry—your funds are now secured but locked.

I presume that this means that the transaction made it in to the chain at the new address, but that the existing Ledger transaction parser can’t parse that transaction, is that correct?

[conradoplg]

It finally happened, congrats!

The blog posts links to GitHub - ZcashFoundation/zecwallet at zondax.mymidnight.blog while your forum post links to GitHub - Zondax/zecwallet-lite: Zecwallet-Lite is z-Addr first lightwallet for Zcash. which seems to be the correct one.

Do you plan to make precompile binaries available for download?

I tried following the README and run into this error:

[1] [550357:1114/192008.351837:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /home/conrado/workspace/zecwallet-lite/node_modules/electron/dist/chrome-sandbox is owned by root and has mode 4755.

Which seems to be an issue with Ubuntu 24.04; Ledger Live amusingly has the same issue. I changed the permission and managed to run. I had to switch lightwalletd servers and then I get:

Error Initializing Lightclient
Error: Unknown keystore variant

Any ideas?

[dismad]

pretty sure --no-sandbox will work , but Im curious for an official response

[conradoplg]

Same issue with --no-sandbox

[Autotunafish]

This was my build procedure

YWallet Q&A

Ok lemme double check something and Ill post back shortly (I wanted to make sure address derivation was the same). You’ll need NPM and NVM for the Yarn build. ‘curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash’ ‘sudo apt update -y && sudo apt upgrade -y’ To verify ‘nvm --version’ You’ll need to use node v16 for this particular binary, otherwise it will likely fail with an openssl error. This is an incompatibility workaround for it (that seems pretty consistent…

Great news that it is also available for the ‘old’ Nano S. Not everyone upgrades to new devices. I will personally wait for Orchard though (hoping it will be possible in the future).
