Zcash Developer Relations Engineer

June 2025

It’s June already!!! Once again, I want to thank the Zcash community, ZCG, ZF, Zingo, ECC, Shielded Labs, ChainSafe, Least Authority, Unstoppable Wallet, ZecHub, Zcash Brasil and all the rest of the ecosystem actors I have the honor to work with on each milestone.

Executive Summary

June was a very hands-on month where a bunch of development happened which ended up in a testnet staging of the Zcash Block Explorer using Zebra as backend by the Testnet Infrastructure grantee. The ZIP-321 Kotlin and Swift libraries developed in previous grants have reached 1.0.0 after passing an audit by Least Authority. In terms of Z3 coordination we set up weekly working calls between Zaino and Zallet devs to iron out API requirements 1-on-1 (in this case many to many) given that the “meeting-less” approach proved not to be as time-saving as it promised to be. This workgroup will extend through the prague Z|ECC summit as the teams conforming the Z3 effort prepare for a Zallet closed alpha phase led by ECC engineers. Weekly updates were posted in the forums and the rudimentary dashboard was updated in ZecDev’s github.io site. Pacu also supported ZCG in different endeavors with a handful of existing and potential ecosystem actors.

Extended Report

  • Zcashd Deprecation
    • Outreach to Zcashd users:
      • So far we got all the responses we could over messaging and current estimates and this is kind of stale. We are going to start doing 1-on-1s as soon as we have alpha builds and containers we can send them over for hands-on testing.
      • Updates:
    • Coordination:
      • Organized the Zaino API workgroup calls and took notes on some of the calls. (except the one I was OOO)
    • Development
      • Worked on Zcash block explorer to find out needed changes in Zebra which led to a PoC integration of Zebra and ZBE and subsequent changes
      • Still waiting for send-max to get a second round of reviews to the changes made from the first review. Rebased to the latest codebase which involved some changes to the code.
