The DeFi environment is rapidly changing, including the technologies and business requirements of the industry. That is why Nextrope developed a platform in an agile methodology that allows responsiveness to the business requirements of the Client. At the same time, Nextrope’s research team delivered consulting and business analysis services.

November 2017 we have published a game using smart contracts as a distribution and transaction mechanism. Nextrope team supported us in the most important part of the project - creating and testing secure blockchain smart contracts on Ethereum network.
