+# Milestone Delivery :mailbox:
+
+**The delivery is according to the official [milestone delivery guidelines](https://github.com/w3f/Grants-Program/blob/master/docs/Support%20Docs/milestone-deliverables-guidelines.md).**
+
+* **Application Document:** [Proposal PR](https://github.com/w3f/Grants-Program/pull/2246)
+* **Milestone Number:** 1
+
+**Context**
+
+The current implementation of [subxtpy](https://github.com/philoniare/subxtpy) has bindings for the most common 
+functionality to read from storage, events, call runtime API and sign and submit extrinsics. The functionality is 
+mostly dynamic at the moment due to the way the macros are run at compile time with Rust. We do believe that static API
+will be helpful to Python developers, so we intend to leverage Python decorators to generate static extrinsic call 
+methods from metadata in the next milestone delivery.
