Digital assets have become an important part of the global economy. Yet, they still oftentimes function in the grey zone due to the lack of convenient tools within the legal field. Indeed, authorities around the world, including the U.S., have been grappling with the question of how to respond to cryptocurrencies.
This encouraged Whitebird to leverage the situation in their country where blockchain and cryptocurrency activities had been legislated. The idea was to develop an efficient and secure solution, which would allow the users to make cryptocurrency transactions legally and transparently.


  • to create an own solution independent from third-party developers
  • to design Front-end solutions for the client’s part and for the service’s administrators
  • to meet the requirements of the bank and VISA payment system
  • to build full-featured Back-end, which will include integration with banking and payment systems and a multi-functional module for managing exchange operations, currency exchange rate, hedging deals, etc.
  • to meet the requirements of the local regulator in terms of business processes, financial reporting, legitimacy of operations, data security, and fault tolerance
  • to establish payment processes and user verification methods according to FATF regulations and the 5th Anti-Money Laundering Directive (AMLD5)


Thanks to a gripping business idea and meticulous, high-quality work on its embodiment, *instinctools team has managed to develop a completely legal and regulated crypto currency exchange service, which embraces the following key features:

Ernst & Young Audit

Our solution successfully passes the annual audit conducted by Ernst & Young. All the business processes, security and privacy solutions, and our KYC and AML procedures meet all the FATF requirements.


The product created in cooperation with *instinctools combines all the most complex cryptocurrency algorithms and processes in a simple and user-friendly interface. It can be adapted to a specific business model and integrated into any system, which would allow working with cryptocurrency. The development of our own solution let us customize all the service processes to meet the regulator’s most stringent requirements. Moreover, direct integrations with vendors reduce operating expenses and provide a competitive advantage on the market.

This project became a sort of a runway for us, from which we took off to new heights. We improved and expanded our knowledge on work and integration with Bitcoin and Ethereum blockchains and banking payment systems. So we are looking forward to sharing our expertise with customers to help them reach their ambitious goals.
