Description:

We need to develop a smart contract that manages subscriptions. Below are the requirements:

Specifications:

1. Language: The contract must be written in the TACT language.

2. Functionality: The contract should support the following functionalities:

   • Sending a red flag to its App subscription collection contract. Each subscription can only send this once.
   • Sending a rate to its App subscription collection contract. Each subscription can only send this once.
   • Renewing a subscription:
     • The contract should be able to receive a renewal request message from its owner.
     • Upon receiving the renewal request, the contract should forward this request to its associated App subscription collection contract.
     • The contract should be capable of receiving a response message from the App subscription collection contract, which provides updates to:
       • Expiration date
       • List of access points
       • List of binded IDs
   • Retrieving subscription information, including:
     • Image
     • Expiration date
     • List of access points
     • List of IDs

3. Conditions:

   • Only active subscriptions (those with an expiration date in the future) can send a red flag and rate.

4. Standards: The contract must adhere to the NFT standard as defined in the TON blockchain TEPs repository.

Testing:

• Ensure comprehensive test coverage for all functionalities mentioned above.

Is your feature request related to a problem? Please describe.
There is a need for a system to manage the minting of subscription collection contracts, collect protocol fees, and make decisions on releasing or blocking frozen apps. This would be a critical component of the Decentralized Subscription Protocol.

Describe the solution you'd like
I'd like to implement the "Protocol App Collection Contract". This contract should:

• Mint subscription collection contracts.
• Collect protocol fees.
• Have functions to release or block frozen apps based on certain conditions (like if over 30% of active subscriptions send a red flag).

Describe alternatives you've considered
While the decentralized architecture of our system requires such a contract, one potential alternative could have been a more centralized approach. However, this would not align with our objective of ensuring anonymity, security, and upholding the principles of decentralization.

Additional context
The "Protocol App Collection Contract" is a core part of our system architecture, interacting directly with the "Subscription Collection Contract". It plays a crucial role in maintaining the integrity and efficiency of the entire Decentralized Subscription Protocol. Implementing this with care and thorough testing is crucial for the success of our project.
