Problem
We had to create a safe, multicurrency wallet for IOS and android devices, so that users can import and manage their accounts. Also, it provides social functionality, such as user profiles, transferring currencies to their friends, etc.
Solution
The solution was to create a hybrid mobile application that connects to the mainnet nodes of the blockchain networks. We stuck to the hybrid React Native solution for mobile development, and Node.js + Nest.js + MySQL as for the backend service.
