Mod Note: created a separate thread where we could discuss the hardware wallets themselves without going too far off topic from the OP of the thread.

Maybe. I’d be curious what’s blocking from a technical standpoint. Maybe it’s not much. Either way once we know that, we know whether there’s a possible way forward.

Trezor did apply for a Grant and did work at one time to support shielded addresses:

Trezor support for Zcash shielded transactions

link: ZF Grants - Trezor support for Zcash shielded transactions Description of Problem or Opportunity Initially, Zcash design excluded the possibility of signing shielded transactions in hardware wallets, since computational and memory resources required for calculating a transaction authorising zk-proof were enormous. In 2018, the Sapling update facilitated this by separating the spending authority from proving authority. This opens a new opportunity for implementing shielded transactions i…

That thread has much of the technical details including pull requests on the Trezor side. I believe it came down to a lack of resources and technical limitations of the hardware.
