Hey everyone! , I wanted to share another project I’ve been working on: **Cometa.py** , its a Python binding for [libcardano-c](https://github.com/Biglup/cardano-c).Cometa.py brings 100% of libcardano-c API to Python with a clean, Pythonic API. It’s built with **CFFI** , fully typed, and packaged for Linux, macOS, and Windows (x86 and ARM), so the native library is bundled and loaded automatically.Features:

- Full coverage of the protocol up to Conway-ere
- Pythonic high-level API with type annotations
- Native library wheels for all major platforms (no compiler needed)
- Extremely fast thanks to direct binding to libcardano-c
- With this binding I also bundled Aiken, so it can compute execution units locally and apply parameters to scripts

If you’re interested:
