Developer community related updates:
- Engaged with contributors and rewarded them for their contributions from our consulting budget.

- Attended Google I/O 2021 & Apple WWDC21 to keep up to date with the latest APIs, cryptography & security related updates on the Android & iOS platform.
Zcash users feature demands which we will R&D on as per bandwidth:
- Passcode/Pin protected app start.
- Contacts management with Z-addresses.
- Deep linking for interacting with ZECpages.
Things to improve on:
- Provide updates on Zcash Forums: As per the grant, we promised to post updates following every Milestone on Zcash Forums, especially after an observation of the forum activity slowing down. So we focussed on connecting with the end users directly for updates and troubleshooting. In the future, we will try to post updates to the forum alongside our alternate channels.
- Investigate optimizing of sync times while maintaining maximum privacy & reducing information leakage. As for the scanning optimizations, once the faster community algorithms are verified and gotten thumbs up from @str4d , we can have those pulled in to Nighthawk for all the efficiency gains.The priority for the next milestone is still NU5 compatibility.
- Improve regression testing to stop vulnerabilities from seeping in to production versions.
We thank @ZcashGrants for funding us and believing in our vision to ship Nighthawk Wallet on App Store, Play Store & soon F-Droid Store with regular updates.
