We're wrapping up a major overhaul to tendermint-rs this week and should be able to help update the KMS to it - includes dropping all Amino and replacing with protobuf.

Current testing status is we've managed to have TMKMS complete the secret connection handshake with Tendermint v0.34 on the stargate-4 testnet.

It's managed to sign blocks and respond, however the signature/canonicalization logic is still using Amino encoding, so the signatures were rejected:

TMKMS is definitely Stargate-compatible at this point
