Key points

The challenge

Our team has faced 2 key challenges while creating this product. The first, it’s payment integrations. And the second, it’s security.

While the first one was crucial for usability the second was the most important aspect. We needed to confirm our system is safe from hacking and the funds of the clients could not be stolen.

Moreover, one of our tasks was creating an internal KYC module that meets the requirements of KYC/AML regulations. Therefore, to summarize we needed to create a legal, user-friendly tool that meets the needs of different client groups.

To create such a substantive project we needed not only to choose the easiest scalable technologies, but also an appropriate and dedicated team. And in the end to choose the vision and specify the distinctions of the project among others.

So we decided to overcome the key inefficiencies of the international banking systems. We focused on developing a tool that is affordable for small businesses. That allows small businesses and individuals to convert currencies and make payments. We were creating cheap and at the same time fast tool for small international payments, the tool that is accessible for e-residents.
