Maintenance & Support Python Libraries (April to September 2023)
Beneficiary:For the last three years, Polkascan Foundation has been maintaining the Polkadot related Python libraries, such as py-substrate-interface, py-scale-codec and several Python bindings for cryptographic RUST crates used by Substrate. These client libraries are essential for Python developers to interact with any Polkadot, Kusama or other Substrate based chain.
As of writing 265 Github repositories and 21 Python packages are depending on our libraries.
With this treasury proposal, we are asking retroactive funding for our activities in the period April until September 2023. This averages out to approximately 4135 euro per month spent on development and tech support activities.
Overview of activities
- Implemented new Polkascan Explorer and Subsquid extensions to the py-substrate-interface extension framework. These utilize indexes from Polkascan Explorer and Subsquid API endpoints, so data can be queried and filtered that is not directly possible or very inefficient on the Substrate RPC.
- New runtime interface: more intuitive approach to interface with the runtime functionality, this is planned to be available in the next major release.
- Added support for ink! v4
- Added SCALE type definitions for upcoming
MetadataV15in Substrate. (Full support is still WIP) - Added multiple params as key support for
query_map() - Add support for runtime calls at other blocks than the most recent #346
- Upgrade contract interface to support
WeightV2#337 - Updated metadata docs for Polkadot & Kusama parachain and stand-alone runtimes
- Technical support on Github and in #polkascan:matrix.org and substrate.stackexchange.com channels

Hello Polkascan team!
KryptosChain has done a video covering this proposal with the feedback if you or anyone else would like to watch, it can be found here.
With that being said, I would be happy to vote Aye for this once it goes on-chain.
Good luck!
