Subscription Payment Manager
Overview
Develop a recurring payment system for subscription services using smart contracts and stablecoins. This project aims to leverage Polkadot's unique capabilities to deliver a seamless user experience while maintaining security and decentralization.
Problem Statement
Current solutions in this space often suffer from poor user experience, high fees, or lack of interoperability. Users need a subscription payment manager that is intuitive, cost-effective, and leverages the full potential of the Polkadot ecosystem.
Proposed Solution
Build a intermediate-level application that implements subscription payment manager using Polkadot Hub's infrastructure. The solution will focus on user experience while maintaining the security guarantees of the underlying blockchain.
Key Features
- 1Secure wallet integration with Dedot or Polkadot-API (PAPI)
- 2Real-time transaction status updates
- 3Multi-currency support for DOT and stablecoins
- 4Transaction history and receipts
- 5Subscription-specific functionality
- 6Responsive design for mobile and desktop
- 7Comprehensive error handling and user feedback
- 8Analytics dashboard for usage insights
Technical Requirements
- •Dedot or Polkadot-API (PAPI) for blockchain interactions
- •Asset Hub pallet integration for stablecoin transfers
- •React/Next.js frontend framework
- •PostgreSQL or similar for off-chain data
- •TypeScript for type-safe development
- •Jest/Vitest for unit and integration testing
- •CI/CD pipeline with GitHub Actions
User Stories
“As a user, I want to develop a recurring payment system for subscription services using smart contracts and stablecoins. so that I can benefit from blockchain technology.”
“As a user, I want to connect my wallet easily so that I can start using the application quickly.”
“As a user, I want to see clear transaction status so that I know when my actions are confirmed.”

Success Metrics
Out of Scope
- Fiat on/off ramps (can be added in future iterations)
- Native mobile applications (web-first approach)
- Support for non-Polkadot chains (focus on ecosystem)
- Advanced trading features (unless specifically required)
Difficulty: Intermediate
Requires solid understanding of blockchain concepts. Involves multiple integrations and moderate complexity.
