Solution

We utilize a Golang-based backend with the Gin-Gonic framework. For blockchain integration, we employ ‘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
