About

# medX: Product Overview - **Patient Onboarding** - Patients create and manage profiles using Smart Accounts (Alchemy). - Provides a secure, decentralized identity for interaction with healthcare services. - **Doctors/Healthcare Providers Onboarding** - In addition to generating Smart Accounts, World ID verification is conducted. - Ensures the authenticity and credibility of healthcare professionals within the medX ecosystem. - **Appointment Scheduling** - Patients schedule appointments with doctors on their preferred blockchain. - Payment is made on the patient's chosen chain, and doctors receive payment on their preferred chain using the CCIP MultiHop router. - **Medical Examination** - Doctors conduct patient assessments and, if necessary, connect patients to healthcare providers for further evaluation or treatment. - **Record Creation and Attestation** - Healthcare providers create medical records for patients. - Records are attested on-chain using Ethereum Account Service (EAS), supported by Alchemy's SendUserOps and gas sponsorship. - **Prescription Management** - Doctors process medical records and generate prescriptions. - Prescriptions are attested on-chain using EAS with the support of SendUserOps and gas sponsorship. - **Prescription Redemption** - Patients redeem prescriptions by paying dues using SendUserOps. - Gas sponsorship covers transaction fees, making the process cost-effective and straightforward.

How it's made

Building medX was all about bringing together the right technologies and tools to create a smooth, decentralized healthcare experience. Here's a straightforward look at how we did it: ## Technologies and Tools Used - **Backend: Node.js** - **What it does**: Handles all the server-side logic, APIs, and interactions with the blockchain. - **How we used it**: We utilized Node.js to manage the backend, ensuring efficient handling of requests, data processing, and secure communication with the blockchain. - **Frontend: Next.js** - **What it does**: Powers the user interface, allowing users to interact with medX in a smooth and responsive way. - **How we used it**: Next.js was chosen for its server-side rendering capabilities, making the frontend fast, scalable, and SEO-friendly. - **Smart Accounts (Alchemy)** - **What it does**: Patients and healthcare providers create and manage their profiles securely, without needing centralized systems. - **How we used it**: We used Alchemy’s tools to make the process of setting up and managing accounts easy and secure. - **CCIP MultiHop Router** - **What it does**: Allows patients to pay on one blockchain, and doctors to receive the payment on another. - **How we used it**: We created custom code that routes payments through the CCIP MultiHop router, making sure transactions work smoothly, even if they're happening on different blockchains. - **Ethereum Account Service (EAS)** - **What it does**: Keeps medical records and prescriptions safe on the blockchain. - **How we used it**: We utilized EAS's private data schema to generate relevant zkProofs, ensuring that patient records maintain privacy while securely storing medical data on-chain. - **SendUserOps and Gas Sponsorship (Alchemy)** - **What it does**: Simplifies transactions and covers gas fees (the cost of transactions on the blockchain). - **How we used it**: We used this to make sure users don’t have to worry about transaction costs, making the platform more user-friendly. - **World ID Verification** - **What it does**: Verifies the identity of healthcare providers. - **How we used it**: When doctors and healthcare providers join the platform, we make sure they are who they say they are using World ID verification. ## Partner Technologies - **Alchemy** - **Why it’s important**: Alchemy provided the tools that made account management and transaction handling easier, allowing us to focus on building the core features of medX. - **CCIP (Cross-Chain Interoperability Protocol)** - **Why it’s important**: This allowed us to create a system where payments can happen across different blockchains, making it easier for users to transact in the cryptocurrency they prefer. - **Blockscout** - **Why it’s important**: We used Blockscout to verify payments, ensuring that all transactions on the platform are transparent and secure. - **Contracts on Base, Optimism, and Celo** - **Why it’s important**: By deploying contracts on these blockchains, medX can operate on multiple networks, ensuring scalability, efficiency, and security. ## Hacky Solutions and Notable Mentions - **Custom Cross-Chain Logic** - We created custom logic to handle payments that move across different blockchains, making sure transactions don’t fail or get delayed. - **Creating the CCIP MultiHop Router for Chainlink** - We were directly involved in developing the CCIP MultiHop router, a key feature that enables seamless cross-chain payments, ensuring that users can transact on their preferred blockchains without issues. - **Gas Optimization** - We worked hard to minimize transaction costs while keeping the platform easy to use, making sure users don’t get stuck with high fees. - **World ID Integration** - Verifying the identities of healthcare providers was crucial. We integrated World ID to make sure that only verified professionals are part of medX, building trust within the platform. - **zkProof for Privacy in Medical Records** - We used EAS's private data schema to generate zkProofs, ensuring that patient records maintain privacy while securely storing medical data on-chain.
