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
- Open the Keystone 3 firmware repository.
- Switch to the
zcash-upstreambranch. - 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.
