Noir Wallet has added Keystone 3 Pro support for managing shielded ZEC from its browser extension. Unsigned and signed transaction data is transferred through QR codes, while secret keys remain on the Keystone device.
What to check
- Confirm that the Noir version you install lists Keystone support.
- Review the recipient, amount, and transaction details on the Keystone screen before signing.
- Remember that transaction privacy depends on the addresses and transaction path used; hardware signing alone does not make a transparent transaction shielded.
Browser extensions remain part of the transaction workflow, so install Noir only from its official distribution channel and keep both the wallet and device firmware updated.
