Project Description

This project, called Tea on-chain, allows users to share information about men they've dated and investigate potential matches on-chain. It is a secure way to share and view information on men before going on a date. The identity of the women is encrypted and verified using zero-knowledge proofs to protect their privacy. We also prevent malicious activity (such as the spread of misinformation by women) through a staking mechanism of PYUSD. If a woman gets reported too many times, she loses her stake and is removed from the platform.

Users can leave reviews on men that other women have posted on the app. Lastly, they can search for men and see reviews that have been left on their profile.

The main appeal of our app is that it appears to be entirely Web2 from the surface but is in fact using Web3 technology under the hood.

How it's Made

This project combines smart wallets from Dynamic, onramp/offramp functionality from Fern, and PYUSD stablecoins to generate a seamless user experience. We also use zero-knowledge proofs to verify the identity of the users on the platform to protect their privacy.

We also used the Gemini API to verify a user's identity and then used snarkjs to generate a proof around it.
