Aether

Aether is a low-code checkout solution integrating Worldcoin’s World ID for user authentication, Mina Protocol for privacy-preserving transaction verification, and Circle’s USDC for payment processing. The solution separates concerns by using Mina for transaction verification while handling payments with Circle’s API on chains that support USDC, like Ethereum. This approach ensures secure, private, and cross-chain compatible payments. Key outcomes include enhanced security, privacy, and seamless cross-chain transactions, creating a robust and scalable checkout experience.

We built Aether to revolutionize checkout with speed, security, and privacy. Here’s how:

Technologies Used:

•	Worldcoin’s World ID: For unique, secure user authentication.
•	Mina Protocol: Ensures privacy with zero-knowledge proofs.
•	Circle’s USDC: Enables fast, secure cross-chain payments.

Integration:

•	Node.js with Express.js handles API endpoints and sessions.
•	World IDKit SDK for smooth user authentication.
•	Circle SDK processes USDC payments across blockchains.
•	Mina smart contracts keep transactions private and secure.

Hacky Approach: To meet the hackathon deadline, we used pre-built modules and a modular architecture, allowing us to move fast without breaking things. Partnering with Worldcoin, Mina, and Circle saved time and ensured top-notch security and scalability.
