SubscriptionManager

Overview

The Secret AI Subscription Manager Contract is designed for subscription-based use cases, where an admin manages subscribers using their public keys. The contract keeps track of registered subscribers and API keys, ensuring that only authorized admins can manage them.

Contract State

The contract stores:

• Admin Address: The account that has permission to register or remove subscribers, manage API keys, and change admin rights.

• Subscribers: A mapping from a public key to the subscriber's status (active or inactive).

• API Keys: A mapping of hashed API keys used for external access control. The API keys are stored as SHA-256 hashes to enhance security.
