[Grant Update] Zcash Wallet Community Developer - Milestone 3
Hello community!
I’m posting the third update to the ZWCD Grant
Estimated tasks from Grant Proposal: (see proposal)
Deliverable 3.1
General iOS 17 release preparations
- Support ZingoLabs on iOS 17 issues
- Support Nighthawk on iOS 17 issues
- Support Zcash iOS SDK and other affected applications that might report issues.
Deliverable 3.2
Zingo Labs: Pull request reviews
Deliverable 3.3
Nighthawk Apps: Pull request reviews
Deliverable 3.4
Fixed time-boxed Allocations (Community calls, office hours, etc)
As reported on Milestone 2’s section, the release of iOS 17 went by with no further complications than teams checking for regressions. The first 3 items were not needed and I repurposed that time allocation into other tasks.
Effective estimated tasks for milestone 3
Deliverable 3.1
Update Advanced Re Org Tests datasets to v5 transactions supporting sapling, transparent and orchard

- TxId mismatch on listing Tx ID reported on `do_send` does not match the one reported on `summaries` · Issue #621 · zingolabs/zingolib · GitHub

Deliverable 3.3
Work around Mobile SDKs and other related projects
Status: Delivered
Remarks:
There have not been clear definitions of what ECC’s roadmap will be in terms of its current scope and development plans. The “focus ECC” Blog posts had indicated development pauses, but the timelines haven’t been either met or updated (see blogpost). At the latest LCWG meetings ECC’s EM had communicated that they were planning their next period and that they would release a blog post to tell the Zcash community their near term plans over the points exposed on their last update mentioned above. This was announced at October 5th’s meeting (see notes) and then confirmed at the following meeting (see notes) but there is no announcement yet (Oct 27th at time of writing). In that context, work allocations that had been planned in terms of this announced “pause” are being repurposed to other efforts.
Achievements:
- Helped review transaction proposal API that will allow complete implementation of ZIP-317 with elements that provide good UX elements.
- Wrote an analysis on SDK, librustzcash and FFI modules to implement REGTEST support

Deliverable 3.4
Fixed time-boxed Allocations (Community calls, office hours, etc)
Status: delivered
Remarks:
Office Hours with AVAX team.
We went over some overall concepts of the ZAVAX bridge. His team is working on implementing the Zcash <> AVAX bridge the same way they did the Bitcoin one for V1 and then iterating to build up a more seamless experience for the user.
I pointed them out to some resources that would be useful for his team like the Protocol section where the difference between Bitcoin and Transparent Zcash are described.
We will be meeting regularly to review some architectural designs and other things related to development and UX.
Office Hours With Chainsafe Team
Meet with Chainsafe Team reps to go over various topics or doubts on their Zcash SDK proposal that I can help address or redirect to the right people.
Met with Danyul from Chainsafe on Thu October 12th 2023. We went over the Zcash Community Grant process in terms of their proposed Statement of Work document
