@Jared-TFL you seems to be stating on Twitter that there is something wrong with our PR @ https://twitter.com/ZaradarBH/status/1631696396746145792 . Could anyone in TFL please give us some actual feedback on what the issues are so we can fix them and get the PR approved? Thx.

Hey, what's the reason to switch to an external npm package for protobuf?

Hey, what's the reason to switch to an external npm package for protobuf?

terra.js is using two version of same npm package '@terra-money/terra.proto'

For Terra Classic: https://github.com/terra-money/terra.js/blob/main/package.json#L86
For Terra 2.0: https://github.com/terra-money/terra.js/blob/main/package.json#L87

However, there is a protobuf update for Terra Classic v1.1.0 (PR: classic-terra/terra.proto#1)
I created a separate repository, https://github.com/classic-terra/terra.proto, and posted an npm package as well, assuming that terra-money/terra.proto will no longer retain the terra.proto version for classic.

I carefully reviewed all the codes that use legacy.proto (same terra.proto but renamed by npm package feature in package.json) and modified the codes that use legacy.proto unnecessarily to use terra.proto.

If you intend to continue maintaining terra-money/terra.proto updates for Classic, I can create a separate PR to terra-money/terra.proto. In this case:

1. This PR will involve quite a lot of code changes as you can see in feat: burn tax split and tax exemption classic-terra/terra.proto#1
   Terra.proto takes terra-money/core as a submodule and creates .js, .py, and .java files from the .proto files there. However, the source code of terra-money/core has a very different structure from the core of Terra Classic, making it inappropriate to create files through submodules. Therefore, I copied all the proto files into terra.proto project instead of using the submodule method.
2. num publish is required in @terra-money/terra.proto@0.1.x version.
