A Web3-based system that autonomously manages subscriptions using smart contracts and on-chain automation

Autonomous Subscription Manager

🚀 Overview

A Web3-powered platform that automatically manages user subscriptions based on usage, payments, and predefined rules using smart contracts.

🧠 Problem

Users pay for subscriptions they don’t fully use. Manual cancellations are inefficient and forgotten.

💡 Solution

Our system tracks usage and autonomously downgrades, or cancels subscriptions using blockchain automation.

🛠 Tech Stack

• Next.js + Tailwind
• Solidity Smart Contracts
• MetaMask
• Monad Blockchain
• x402 API payments
• Node.js backend

🔗 Smart Contracts

Deployed on Monad testnet for subscription logic and payment handling.

⚙️ How It Works

1. User connects wallet
2. Subscribes via smart contract
3. Usage tracked via API
4. Automation triggers contract actions
