About

Anon Aadhaar Core is the cornerstone of the Anon Aadhaar protocol, encompassing all essential TypeScript components needed to interact with our cryptographic circuits. At its heart lies the innovative PCD framework from Zupass, which we leverage for structure and typings.

Key Features:

• Interface of our Circuits: Directly interfaces with the Anon Aadhaar Circom circuits.
• Use of PCD Framework: Utilizes the PCD framework from Zupass for robust data processing.
