tx signer

[cxyzhang0]

Hi,
In example config, there is an optional section for tx_signer. Also, in the tmkms framework, secp256k1 account keys are supported in addition to ed25519 consensus keys. Since CombetFBT only uses ed25519 keys for validators, I assume the secp256k1 keys in tmkms are intended for tx signing only.
I'd like to use the tmkms tx_signer function to have tmkms manage my hsm-backed validator k256 account keys to sign such transactions as slashing, etc. How can that be done?

TMKMS had legacy support for transaction signing using Amino, but it's long-since removed (see #764).

The current secp256k1 support is for consensus keys (see #644). Notably the Band Protocol uses secp256k1 consensus keys.

@tony-iqlusion thank you for the info. I guess I will look for a wallet solution for the validator tx signing key.
Also it is good to know k256 is being used for validator block siging.
