Problem
Here, the MsgTransfer type does not have the memo field.
According the ICS spec, I think it should include the memo field, which is used for ibc-hook module of Cosmos-SDK.
This memo field is needed for advanced functionality, like cross-chain-swap.
Suggestion
I think the maintainers should include the latest proto files, and rebuild the TS types for juno network.
Then, it can include the new field - memo into the TS MsgTransfer type.
