For the last four years, Polkascan Foundation has been maintaining the Substrate Python API: [py-substrate-interface](https://github.com/polkascan/py-substrate-interface), [py-scale-codec](https://github.com/polkascan/py-scale-codec) and [several Python bindings](https://github.com/orgs/polkascan/repositories?q=&type=all&language=rust&sort=) for cryptographic RUST crates used by Substrate.

The Substrate Python API is a library, with similar features as [Polkadot-JS API](https://wiki.polkadot.network/docs/polkadotjs#polkadot-js-api). With this API, Python developers can build apps that interact with any Polkadot, Kusama or other Substrate based chain. There are [APIs for different programming languages](https://wiki.polkadot.network/docs/build-tools-index#rpc-and-api-tools) and our API library is at the moment the only one available for the Python programming language.

As of writing [353 Github repositories and 31 Python packages](https://github.com/polkascan/py-substrate-interface/network/dependents?package_id=UGFja2FnZS04OTc2NTczNTM%3D) are depending on the Python API.

With this treasury proposal, we are asking retroactive funding for our activities in the period January until March 2024.  

Requested funding: 9,831.25 EUR

- **Problem Statement:** Polkascan Foundation seeks retroactive funding for maintaining the Substrate Python API, crucial for Python developers interacting with Polkadot, Kusama, and other Substrate-based chains.
- **Significance:** The Python API is the sole available library for Python developers, with 353 Github repositories and 31 Python packages currently dependent on it.
- **Proposed Solution:** Requesting 9,831.25 EUR for funding activities from January to March 2024 to sustain the Substrate Python API.
- **Expected Outcomes:** Continued support for Python developers to build apps interacting with various Substrate-based chains.
