The Python Anchor client with support for new Anchor IDL formats (fork of anchorpy by kevinheavey)

AnchorPy3

---

Note: This is a fork of kevinheavey/anchorpy with added support for new Anchor IDL formats (v0.1.0 spec). All credit for the original implementation goes to kevinheavey.

What's New in AnchorPy3

• Full support for new Anchor IDL format (v0.1.0 spec) with precomputed discriminators
• 100% backward compatibility with legacy IDL format
• Automatic format detection - works seamlessly with both old and new IDL files
• Decoupled architecture - anchorpy-core is now a separate package
• Updated for Python 3.10+

Overview

AnchorPy is the gateway to interacting with Anchor programs in Python. It provides:

• A static client generator
• A dynamic client similar to anchor-ts
• A Pytest plugin
• A CLI with various utilities for Anchor Python development.
