Zallet alpha.2 is out! go check it out!
https://github.com/zcash/wallet/releases/tag/v0.1.0-alpha.2

Another week, another Zcash Z3 development update.

As you may have noticed, we flipped our ring-signatured cousins both in price and market cap and almost 10x on daily volume. These last weeks have brought an influx of users and new edge cases that put our wallet software into stress test and while it is going very well, this takes a huge toll on code developers’ availability to work on Zcashd deprecation since prod issues > backlog github issues. As I said in yesterday’s Arborist Call, we all met and re-assessed our timeline and although we are missing the end-of-2025 milestone, we are not missing it for much. We have changed a bit how we are working to cope with this “All eyes on Zcash” effect.

ECC posted a Roadmap update on X which reflects this

Outreach

Status: Resumed :white_check_mark:

We continue nudging people on Zallet Alpha and reminding them to update their Zebra and Zcashd nodes before November 23rd.

Zebra

The Zebra team continues working on improvements and collaborating with ECC on the RPC Testing framework and testing of Zallet.

Zaino (ZingoLabs)

  • Status: in progress

Project Board

Zingo is working on adopting Zebra 3 and wrapping up the Chain index and block explorer support work and deprecating lightwalletd. More info on block explorer support in the corresponding section below.

  • Status: Alpha Released :white_check_mark:

tracking work on this repository.

As I mentioned, the ECC team had been busy responding to bug fixes on Zashi. But that didn’t stop them from cutting a new Alpha release. We have worked together on a way to organize contributions into Zallet and PR reviews into Librustzcash to alleviate as much as possible the bottlenecks of the Z3 development pipeline and grow our overall capacity over time. Reviewers don’t grow overnight like mushrooms after a heavy rain, but we won’t have new reviewers if we don’t start investing in fostering these roles regardless of the initial overhead this may have.
