Problem Client came with requirements to create a multifunctional application for storing, buying and professional trading of cryptocurrencies, as well as storing NFT tokens.
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. We also had an integration with Opensea's and a number of crypto-trading platforms' public API's to implement trading and NFT functionality.
