Impact of the deprecation of Ledger Nano S hardware wallets for Tezos users

Project Updates
1

Ledger has recently announced that they have discontinued their Nano S hardware wallet model. As part of this process, they have stopped accepting updates for any embedded application. Consequently, there will be no new updates for the Tezos Ledger baking and wallet apps for this hardware wallet. Future updates will be available for newer models, such as Nano S+, Nano X, and others.

While the latest versions of the Tezos Ledger baking and wallet apps for Ledger Nano S are fully compatible with the current protocol on Tezos L1 and remain functional, this may change in the future.

Notably, our upcoming S protocol proposal introduces changes in the encoding of reveal operations that would require updating Tezos Ledger apps to ensure compatibility.

Should this protocol proposal be accepted and activated on mainnet, users of Nano S devices may still be able to sign transfer operations but will no longer be able to reveal the public keys of new (or empty) accounts — severely limiting functionality.

Thus, we strongly encourage Nano S users to consider upgrading to more recent hardware wallet models, or to seek alternative solutions to ensure continued compatibility.

what other wallet options are available? presumably this should be done when also switching over to a tz4 wallet address for baking as well. how does one go about updating the baking address associated with our bakeries? didn’t think this was possible as our profile is associated with one existing wallet address

You keep the old baker address, but you use a tz4 consensus and companion key. So stakers and delegators will keep using the old address. You can try it out on one of the S testnets.

It doesn’t look like any of the devs are recommending to use ledger devices with bls. Signatory cites performance problems: Release Signatory v1.2.3 - "BLS Proof of Possession Support" · ecadlabs/signatory · GitHub So theoretically you could do it, but not recommended. The other tz1/2/3 schemes will keep working however.
