cardano-serialization-lib VS cardano-graphql

You will need cardano-serialization-lib for that. Check out their github repo: https://github.com/Emurgo/cardano-serialization-lib

Please allow me to introduce you PyCardano, a Cardano library written in Python. It allows users to create and sign transactions without depending on third-party Cardano serialization tools, such as cardano-cli and cardano-serialization-lib, making it a lightweight library, which is simple and fast to set up in all types of environments.

The Flint backend is open source (https://github.com/dcSpark/cardano-backend), the SDK we manage is open source (https://github.com/Emurgo/cardano-serialization-lib/) and the way the wallet works is documented via multiple CIPs (ex: https://github.com/cardano-foundation/CIPs/tree/master/CIP-0030)

Yes, that's dcSparks the team behind Milkomeda ( https://github.com/Emurgo/cardano-serialization-lib ), all thanks to them! Catalyst is great but I wonder why isn't IOHK financing this directly, because compensation for this kind of work through Catalyst is not great, considering how much a Rust dev can get in the market and work elsewhere.

Be aware of this issue if you try it.

But anyways, even none of the code examples they list on docs(https://docs.cardano.org/cardano-components/cardano-serialization-lib) or in their github repos(https://github.com/Emurgo/cardano-serialization-lib/blob/master/doc/getting-started/generating-transactions.md) work at this point. You can give it a try if you are interested. So I'll pause this project for a while, and report back as soon as it at least functions.

I think CHEFF is referring to https://github.com/Emurgo/cardano-serialization-lib

There are a few different Github repositories that server different things -- I'm not sure if there is a list of all of them. The job posting would mostly be related to https://github.com/Emurgo/cardano-serialization-lib and the network lib https://github.com/2nd-Layer/rust-cardano-ouroboros-network

looking to avoid deploying our own instance of https://github.com/input-output-hk/cardano-graphql, and the current REST implementations of different providers arent expressive enough for our use case.

I'd suggest to use either cardano-graphql or Ogmios which both provide direct interfaces for querying stake addresses' balances.

More about that here https://github.com/input-output-hk/cardano-graphql
