April 25th
Hello! Another week! Another Zcash Z3 update!
Outreach
The Z3 team is working on some request for information that came back from some bug partners for them to prioritize the integration of the new Zcash stack into their work planning.
Zebra
Project Roadmap board
Priority board
@pili has posted an excellent summary of ZF’s past sprint! Don’t miss it! Nothing to add on my part!
Once more I want to recognize Pili’s work on work visibility to the public developer community of the whereabouts and progress of her team. If you take a stroll by the Zebra boards you’ll see how everything is laid out and that’s a ton of work that does need to be often recognized and appreciated.
Zaino (ZingoLabs)
- Status: almost back on track!
Zallet integration is helping to iron out some integration wrinkles and also revealed some shortcomings of the overall Zcashd deprecation planning during Q3 2024 that revealed themselves during this phase of development which teams are working together to address.
Last update I mentioned that Zaino folks were progressing with something called “remote read state service”. During conversations with the ECC team Zingo folks learned that this functionality was not finally needed this early and that Zallet folks would have expected some items in the follow-up grant “Complete Zaino” to be developed instead among other things. @ZingoLabs and @ZCG are working out a way to fit these priority changes into the existing grant structure and minimize budget impact on Zingo as org and Timeline impact to the Z3 project.
Despite all of this progress keeps its pace and every day it passes we are closer to our goal.

@str4d and @nuttycom have taken the time to create the github issues of the RPC methods to be implemented and this is a great opportunity to start contributing to the Z3 stack.

The ZeWIF team is definitely looking for PRs from the community at this point, to make sure we have all the abstractions for wallet contents right. Just be sure you have the latest pull, since the repos were updated this morning.
Regtest? What is that?
