As an MVP, one of the requirements was developing a product with minimal time and budge.

money transfers, cryptocurrency exchange, and wallet in one app

When we were introduced to the project, another team was already developing LetKnow ID and App. Therefore, we focused on developing money transfer, crypto exchange, and wallet parts.

The design team created the wireframes and design for LetKnow Exchange to meet the client’s guidelines.

Rubyroid Labs development team customized the digital asset platform BitGo to adapt it to LetKnow’s business goals and deployed the node for Ethereum inside the application.
