Nighthawk update for June 2022

In June, our priority was to maintain Nighthawk product suite compatibility with NU5. And Nighthawk Wallet celebrated its 2nd anniversary by releasing the redesigned Android app via beta testing channels & F-Droid!

Nighthawk Wallet Android redesign was completed with Transfer ZEC workflow implementation. Here are some screenshots of the new flow which includes a transaction preview before broadcasting it to the Zcash network:

Nighthawk Wallet updates:

  • Release a bugfix for checkpoint format, thanks to @Pacu for finding the root cause of the issue affecting new wallets created post NU5.
  • Discuss the upcoming changes with Group OMR with @thomaslzy.
  • Provide end-user support to new users of Nighthawk Wallet.
  • Plan to review the feedback regarding the Nighthawk Wallet redesign and make a public release after language translations are completed.
  • Full App Changelog is available at

:wave: Shout-out to Ian for creating a video walkthrough of Nighthawk Wallet

  • Work towards hosting a test-net version of Zcash Block Explorer.

Goal: Add Zcash to Thorchain to enable decentralized ZEC trading and LP incentives.

  • BiFrost
    • Helm repositories have been updated with NU5 support.
    • Test suite v5 has been taken care of, and JSON fixtures have been updated with v5
    • Continue working towards adding support for v5 transaction compatibility.

And that’s a wrap for our June update. We congratulate ECC & ZF for a successful network upgrade that brings us to the Age of Trustless Shielded pools!


Looks easier, thanks for the great work

These are all great but I’m having a lot of trouble using Nighthawk lately. It seems to be getting slower and slower. Today it took 40 minutes from opening the app to finishing scanning.

Any note on what’s happening?


ZWL and Ywallet are a little slow but not too bad (transacting on both work), yeah my NH is just stuck on preparing to scan, motionless
Wait, there it goes ok well see…
Yep just took a little while :+1:
