A library for interacting with cosmos based networks

NOTE: This is normally one-off step. In the case, that completely new version of Cosmos-SDK is required (see the COSMOS_SDK_VERSION variable in the Makefile), it might be better to force it to re-fetch manually again - please run following command in that case:

make fetch_proto_schema_source

NOTE: Please note that source protobuf schema files are intentionally NOT committed in this repo, they are fetched on demand and stored as local files.

Run the following command:

make generate_proto_types

NOTE: The Cosmos-SDK is intentionally not made part of this repository (e.g. via git submodule ..., or git subtree ..., or by-value( trivial copy). The reason being to minimise filesystem footprint of this repository. It is NOT necessary to store Cosmos-SDK protobuf schema files in this repository, only python types generated out of protobuf schema is actually necessary. The makefile target id implemented the way, that necessary bits & pieces of Cosmos-SDK repository is downloaded on demand (for python types generation), but they are NOT checked-in to this repository
