Ironwood Testnet Support Now Available on Keystone ForgeBox

Ironwood testnet support is available for developers using Keystone ForgeBox. The test build also supports signing batches of 11 or more transactions through one QR workflow.

How to test

  1. Open the Keystone 3 firmware repository.
  2. Switch to the zcash-upstream branch.
  3. Follow the repository build instructions and flash the resulting test firmware to a ForgeBox.

Important limitations

  • Self-built firmware is not signed as an official Keystone production release.
  • The build is intended only for ForgeBox development and testing.
  • Do not attempt to install it on a Keystone 3 Pro production device.
  • Production users should wait for an officially signed firmware release after the testnet work stabilizes.
