Project Description

How it's Made

The WalletChat extension is built with both centralized and decentralized tools to ensure great user experience while upholding the ethos of decentralization - all chat data is encrypted using LIT on the client side and only the encrypted blob is stored in our backed DB on a per-message basis.

On the frontend, we use React with Typescript. Chat data is fetched through a REST API from a centralized database to display messages received and sent by the user. During the EthGlobal Hackathon, we added JWT authentication to the open source API and started using LIT for DM encryption.

For the backend of the WalletChat program, For EthGlobal2022 we used the opensource api located at:
