How It's Made

1. Backend Architecture:

   • Built on a robust cross-chain infrastructure leveraging Ethereum blockchain technologies.
   • Key components include:
     • EAS Attestation: Used to verify merchant ownership and store preferences securely.
     • Non-Transferable ERC721 Tokens: Used to represent unique pointers for each user.
     • Role-Based Access Control: Admin roles are established to manage key functions like setting base URIs and updating pointers.
     • Secure and Non-Rentrant Functions: Protect against reentrancy attacks, ensuring secure and reliable operations.

2. Frontend Implementation:

   • Developed with React, Node.js, and npm for seamless integration.
   • Secure payment processing through SwapKit API and SDK, facilitating cross-chain payments.
   • The attestation process is managed using the Ethereum Attestation Service (EAS) SDK, ensuring that merchant details and preferences are securely stored and verified.
