A Path Forward for Ledger and Zcash

Hi everyone,

I’m Abhi, part of Ledger’s Coin & Blockchain Integration team. I’m taking over external communication for this integration from Victor (@vf-ledger), who recently left Ledger.

Current integration status:

Zcash Device App

  • Implementation of UFVK sharing and Orchard Unified Address generation in the device app is complete. The OS release (including ZIP-32 support) has been rolled out to 50% on April 22nd, after which we will conduct final testing and proceed with the 100% release.
  • We have initiated work on Orchard transactions and Clear-sign, including Orchard-to-Orchard (private send), Orchard-to-transparent, and transparent-to-Orchard. A significant portion of the work remains, and completion is currently targeted for mid-May, subject to progress.

Ledger Wallet (Desktop)

  • The synchronization process is complete, and the next phase is dedicated to intensive performance and UI testing. At this point, we are able to sync and decrypt the full Zaino node (since Orchard birth) in under 65 minutes as a benchmark. Actual performance will vary depending on the user’s hardware.
  • Transaction crafting for the different flows (Public, Private, Public → Private, Private → Public) is currently being worked on.

Full scope release

We’ll share an updated launch ETA in our May update. We are targeting end of July for the release of the full scope.

For anyone who would rather follow real-time progress than wait for monthly summaries, active development is visible in public LedgerHQ repositories:

Next update by end of May 2026.

Note:

The existing transparent Zcash app on Nano S will not receive further updates. Nano S has been deprecated for some time, and per Ledger’s policy we no longer publish app updates for it outside of exceptional cases such as security fixes.

For users with ZEC on a Nano S, the path is migration to a supported device (Nano S+, Nano X, Flex, Stax, Nano Gen5).
