Subscription Renewal Reminder

This project is a decentralized subscription renewal reminder system built on the Ethereum blockchain. It leverages Ethereum smart contracts to manage user subscriptions, including storing their details such as start time, duration, and active status. The smart contract emits an event when a subscription is nearing its expiration, prompting users to renew their subscription.

The system includes an off-chain listener implemented in Node.js with Web3.js, which monitors the blockchain for subscription expiration events. Upon detecting an upcoming expiration, the listener sends a personalized email notification to the user, reminding them to renew their subscription. The backend is powered by Nodemailer for email alerts, and it can be extended to incorporate Web3 push notifications.

By using this system, users can rely on automated reminders and renewal processes, ensuring they never miss their subscription deadlines. This decentralized solution ensures transparency, security, and automation, making subscription management efficient and hassle-free for users in any blockchain-enabled ecosystem.

Future enhancements for the project include integrating automatic subscription renewals, providing a web dashboard for subscription management, and expanding the notification system with Web3 push notifications to keep users engaged in real time.
