⚙️Product Architecture

The SUB Protocol leverages blockchain technology to provide a decentralized platform for managing subscription services. This document outlines the technical aspects of SUB Protocol, focusing on integration with Chainlink Automation (formerly known as Chainlink Keepers) to ensure reliable, automated transactions for subscription renewals and payments. The protocol utilizes smart contracts deployed on a blockchain network to facilitate secure, transparent, and automated subscription management with $SUB tokens.

Architecture

Smart Contracts

SUB Protocol's core functionality is encapsulated within smart contracts, which are deployed on the blockchain. These contracts handle subscription creation, management, payments, and renewals. Key components include:

• Subscription Contract: Manages individual subscription agreements between service providers and subscribers.

• Payment Processor Contract: Handles the transfer of $SUB tokens from subscribers to service providers based on subscription terms.

• Access Control Contract: Determines subscriber access to services based on active subscription status.

Chainlink Automation Integration

SUB Protocol integrates Chainlink Automation to automate subscription renewals and payments. Chainlink Automation provides decentralized, reliable, and tamper-proof automation of smart contract functions, essential for managing periodic subscription payments without manual intervention.
