Nighthawk update for July 2022

In July, our priority was to keep up with the demand of lightwalletd as we noticed increased usage overall, and to make Nighthawk Wallet releases to keep up with wallet syncing issues.

We invited members of the Zcash community to contribute language translations and we would like to thank the first group of 7 contributors who’ve helped translate strings into Arabic, Spanish, Russian & Ukrainian!

The major outstanding issue remains the ability of light wallet infrastructure to hold up the ongoing high transaction load and to provide a seamless Zcash experience on mobile. We will continue to work on building support for NU5 & Orchard pool transactions as per the spec and ZIPs to support both Sapling & Orchard transactions in the coming future.

The Nighthawk team is also participating in discussions with core engineers around changing the transaction fee format and distributing lightwalletd server load.

Nighthawk Wallet updates:

  • Make new wallet releases with improved type safety, upstream SDK updates, upgraded dependencies, and support for Android 13 & iOS 16
  • Keep up with sync calls with @thomaslzy to monitor the progress of the OMR library.
  • Provide ongoing end-user support to new users of Nighthawk Wallet.
  • We would like to extend thanks to ECC engineers who have helped troubleshoot issues over the weekend & long weekends too.
  • Full App Changelog is available at https://nighthawkwallet.com/changelog/

BONUS: We’ve partnered with Unstoppable Domains to make it easy for our users to send and receive ZEC! All external services will be opt-in, i.e. Nighthawk users will manually need to enable UNS address resolution. This is in line with the focus of the privacy-first approach taken by Nighthawk.

And that’s a wrap for our July update. We will be present at Zcon3! Stay tuned for @aiyadt’s session on Intro to Zcash & collecting general feedback around light wallets to share with the light wallet devs at Zcon3!
