Hi, any DApp can be integrated in Ledger Live by following the doc here: Introduction | Developers
It would require development effort to adapt Tornado Cash DApp and also to develop a plugin to the Ethereum Nano app.
The objective is to improve UX for Nano users and also to improve security by ensuring the correct smart contracts are being interacted with and also by no longer “blind signing” the txs.
As Tornado Cash DApp is not open source, the goal with this topic is to get a signal from the community if these changes are worth looking at or not.
The code for the Nano plugin can be done by anyone so I guess it would only be a matter of funding it.
Thank you for your time and please let me know your thoughts.
