All ECC teams focused on wallet performance

Ok folks! Zooko the Engineering Manager and Product Owner reporting in. I’m delighted to report that we’ve released ECC Mobile Zcash SDK 2.0 Release Candidate for iOS and Android!

For iOS: Release Zcash IOS SDK release 2.0.0-rc.1 · zcash/ZcashLightClientKit · GitHub

For Android, get zcash-android-wallet-sdk 2.0.0-rc1 from the sonatype Maven repository. (URL: Central Repository: cash/z/ecc/android/zcash-android-sdk/2.0.0-rc.1 )

This release implements Spend Before Sync! Meaning that users should be able to spend their ZEC without waiting for the syncing process to finish. Sync can now be, from the user’s perspective, a “background” process that they don’t need to care about.

This version has been tested internally by our team at ECC and has no known bugs that would have a high impact on users.

Here’s the remaining plan for the final release of SDK 2.0. We intend to make no changes from the 2.0-RC to 2.0-final except for bugfixes that are high impact and that seem sufficiently safe of a change to make.

  • :ballot_box_with_check: #1179 and #1180 done (the last week of August).
  • :ballot_box_with_check: #730 and #899 #936 #908 completed
  • :ballot_box_with_check: Rest of the mobile code – code complete Friday 2023-09-08 excluding acceptance testing
  • :ballot_box_with_check: Fix bug (#963) discovered during acceptance testing
  • :ballot_box_with_check: Code review of mobile code changes, release SDK 2.0 Release Candidate Wednesday 2023-09-13
  • ☐ Acceptance testing (potentially using Zashi beta) complete by Monday 2023-09-18. Release SDKs 2.0 Final! (* Assuming no bugs discovered in acceptance testing that require code changes that set back the schedule.)
  • ☐ Ask for a thumbs up from Nighthawk, Edge, and Unstoppable that the release looks okay, make public announcement Friday 2023-09-22 if we get word from the wallet partners early enough or if not then public announcement on Monday 2023-09-25.

Many thanks to my team at ECC for working long and hard to make this the best it can be! :smiling_face:
