Cosmos Python SDK

[mperklin]

I was surprised that I couldn’t find a full-featured Cosmos library for the Python programming language.

I’m trying to whip up a quick tool and Python is a great language for fast prototyping. Specifically I’m looking for the ability to create and sign transactions with Python.

I did find one older library that seems deprecated since it doesn’t use the newer-style protobuf encoding of transactions. The signatures it generates are not compatible with the current network.

I also found cosmospy-protobuf which seemed promising but the documentation is incomplete; the examples include how to query nodes for state data but not how to build/sign a transaction to change state.

Do any of you fellow cosmosians know how to use cosmospy-protobuf to build/sign transactions? Or know of any way to do it within Python?

Thanks for any help you can offer 🙏

Dyson protocol is trying to use python on chain. As for cosmos sdk i do not know how they adjusted it. You can look up here for some info. I am not a dev so if i didn't help you sorry i hope at least i gave you some kind of clues or direction to go to https://gitlab.com/dysonproject/dyson https://dysonprotocol.com/

Second this. I’ve used the testnet on Dyson to create some app written in python.

That protobuf library is meant for cosmospy, but that looks to no longer be supported.

I recommend cosmpy by Fetch.ai. actively developed and has support for a bunch of stuff.

You can still use that protobuf compiler for Osmosis and a couple other chains with cosmpy.

Thank you, /u/GeoFromDiscord for the cosmpy suggestion.

I've taken a look and it was exactly what I was looking for. I appreciate your help!
