Project Description

This project combines a ZK-hub\module and mobile-based frontend to allow users to deposit, withdraw, send stable coins without paying gas and using emails as social ID, leveragng orzacles and ZK-EVM infrastructure. This module is a part of suite of API and web3 tools powering cross-border e-commerce payment processing, offshore mass payouts, and remittances specifically built for underbanked people.

How it's Made

We utilize a Golang-based backend with the Gin-Gonic framework. For blockchain integration, we employ β€˜goeth,’ and as our node, we rely on Alchemy. The backend is responsible for sending signed transactions from the frontend and maintaining a transaction history, which is stored in a Postgres database. On the frontend, we use React Native, which implements the MPC Wallet logic and distributes parts of the keys to various storage solutions. We adhere to the philosophy of a universal frontend for different blockchains, so the frontend is solely responsible for transaction signing. Transaction preparation and transmission are handled by the backend
