backend-assessment-001

Objective:

Integrate the JustaName SDK (@justaname.id/sdk @justaname.id/react) into a platform, utilizing a React frontend and a NestJS backend. The claiming logic should be handled from the backend and the frontend should call an API to claim the subnames

Tasks:

1. Register an ENS Domain on Sepolia Testnet

   • Set up an Ethereum wallet if you haven’t.
   • Use a Sepolia faucet to get test ETH.
   • Register an ENS domain on the Sepolia testnet.

2. Access the JustaName Admin Dashboard

   • Go to JustaName Admin Dashboard.
   • Import your newly registered ENS domain.
   • Generate an API key.

3. Create a Claim Page with Two Options

   • Develop a frontend page where users can claim subdomains.

   Features:

   • Claim Normal Subdomain: Allow users to claim standard subdomains.

   • Claim Admin Subdomain: Enable users to claim admin subdomains at the root domain level. Include a textRecord for admin subdomains as follows:

     {
        "key": "admin",
        "value": "[\"subname1.example.eth\"]"
     }

4. Bonus Task: Create an Admin-Only Page

   • Implement Sign-In with Ethereum (SIWE) login mechanism.
   • Develop a page that is accessible only to users with admin subdomains.

Deliverables:

1. Source code (Frontend and Backend) hosted on a Git repository.
2. Documentation outlining how to set up, run, and test your solution.
3. Demonstration video (optional but encouraged) showcasing the functionality of your application.

Evaluation Criteria:

• Correct integration of the JustaName SDK.
• Functionality of the claim options.
• Implementation of the admin-specific functionalities.
• Code quality and documentation.
• Software Design & Practices (SOLID principles, Testing (unit, integration…), design patterns)
• Bonus points for successfully implementing the admin-only page with SIWE login.
• Bonus points for successfully dockerizing the backend
• Bonus point: Demonstrate possible solutions for scaling the application (if applicable)
