I switched to using the legacy amino sign mode but my transactions are still failing the signature verification step.

Steps: - Tx info is serialized with serde_json and sent via apdu to the ledger. ```json { "account_number": {number}, "chain_id": {string}, "fee": { "amount": [{"amount": {number}, "denom": {string}}, ...], "gas":...

sounds good to me. Well thanks for your help on this issue! Really appreciate it. If you come up with any other ideas for how to get this to work...

Following up here! Did some digging and found that [tmkms](https://crates.io/crates/tmkms) uses your stdtx package to solve exactly this problem. Examples can be found in tx_signer.rs. I'll be using that as...

@tony-iqlusion you mentioned above that it might be possible to get amino support within cosmrs and I think that's exactly what my use case requires! I'll try and build around...
