We're getting the following error trying to use legacy amino multisignatures with our Ledger-based custody setup:

Unfortunately to our knowledge there is not a Ledger app which supports the new Protobuf-based signature format.

I'm not sure if this was removed from Tendermint itself, or if you need additional logic to support it, but it's worked with every other chain we validate on.

Curiously, this guide makes it look as if it should work: https://github.com/tharsis/evmos/blob/23a445a/docs/guides/keys-wallets/multisig.md#step-4-create-multisignature

@tony-iqlusion that guide was probably written back when secp-generated addrs were supported. This is no longer the case.

[tony-iqlusion]

So it seems we're not going to be able to use the original account address we provided because it's using secp256k1.PubKey Ledger keys.

We are looking into either signing an EIP712 message with a Ledger or attempting to move to a software-backed multisig account. Is it OK that the address will no longer match what we originally provided?

[tony-iqlusion]

Alternatively, if it seems like EIP712 + Ledger + multisig will be supported in the near future, perhaps we could create our validator some time after genesis when it is supported.
