Developing your own cryptocurrency custodial wallet solution can be daunting and time-consuming. Not only do you have to build all the basic functionality such as creating an account, user management, and transactions like buying, selling, and swapping. You also need to connect your custodian wallet to a reliable and secure cryptocurrency infrastructure.
To get to production quickly and efficiently, we have released a complete crypto custodian infrastructure solution consisting of a backend API for managing customers, transactions, and crypto balances and a mobile sample application.
The API backend handles the mobile app OAUTH authorization and stores the sensitive customer data at an in-house location. Moreover, it creates a secure connection with the NEXUS backend API, which supports different cryptocurrency operations and allows customer data handling. You can use this API and integrate it into your backend system.
The cryptocurrency custodial wallet sample application is developed in React Native. The sample application can be used as a basis for your wallet application and can carry out all the operations discussed above. You can customize the application to your needs by cloning the repository on Gitlab.

You can easily connect to your front and back end, creating a unique white label solution customized to your business needs—more information on crypto infrastructure solutions.
