Monterail met our expectations right away

We’re really happy with the code’s quality that has been given to us. At ZebPay, the goal is to hire A+ people, and we don’t want to compromise on quality when we hire developers, so the process usually takes some time. Monterail met our expectations right away - we got the people who were really trying to understand us.

Scope and Highlights










The Challenge

With the rapidly growing number of transactions, the number of users, and the ever-changing price of cryptocurrencies, the ZebPay team had to ensure that their web application would be performing flawlessly and could handle all of these.

The previous version of the product’s code was written in Angular back in 2014 when ZebPay was just starting, and required updating it to modern market standards so it would no longer be considered legacy.

Right before our partnership started, the ZebPay application was at its peak, with daily trade volumes at 40-50 million USD. It urgently required improving the code’s structure and documentation as well as UX/UI changes that would improve the overall experience for ZebPay users.

Unlike other finance apps, ZebPay needed a very high-performing application able to show results in microseconds because the price of cryptocurrencies changes so fast. Another challenge here was the fact that the web application has multiple features, so any development decisions had to be made while considering the scalability and magnitude of the final product.

Key challenges

Ensuring the highest level of performance of ZebPay’s web application.
Thorough and clear code documentation for all team members.
Updating the UI/UX of the web app to modern standards, with refreshed details.

The Process

For the company, it was clear from the start that Monterail has previous experience with cryptocurrency exchanges and the sector in general.

In the initial stage of this project, our teams worked closely and focused on preparing documentation that could be then used to build new features and revamp the web application.

This stage of the project included creating code documentation, implementing UX/UI changes as well as backend development to improve the app’s overall performance. The product was rewritten in React - with the previous version built in Angular, following our research and the discussions with the ZebPay team. The Monterail developers and Project Managers were then responsible for the development process and for making sure that both parties operated in sync.

Our core efforts at this stage included:

  • Daily standup meetings with the ZebPay team to ensure our goals and tasks are aligned.

  • Building comprehensive documentation that was then adopted for further development undertakings.

  • Working in close collaboration with the client’s specialists as internal advisors and engineers.

Advisors to the client’s team

With this project, we were able to work as internal advisors to the client’s team and we worked as a team, so there weren’t any differences in approach and workflow between internal and external team members.

The Outcome

The result of our collaboration is a rebuilt web application written in React.

The product has a modern look and feel, with the web app aimed at increasing the number of ZebPay users who access their wallets this way.

The web application was in the testing phase first and then it was launched successfully in November 2022.

The success of this project hinged on the following factors:

  • Quick ramp-up time - both teams were able to start working within 15 days after the initial discussion about the business side of the project.

  • Extensive documentation was created as the first step of our partnership.

  • Monterail’s expertise and experience with React web development and cryptocurrency projects.
