Exchange Coin (EXCC) aims to build a decentralized Cryptocurrency exchange (DEX) dedicated to semi-professional Cryptocurrency traders that allows seamless and secure multi-blockchain transactions. To achieve that, we had to create a new Blockchain based on Proof of Work mixed with Proof of Stake algorithms. 

Business challenge

EXCC founders, after the successful ICO, struggled with finding a reliable technological partner who could take care of advanced Blockchain technology development. Pragmatic Coders provided a dedicated cross-functional Product Team (including Blockchain Developers as well as Backend and Frontend Developers, a Product Owner, and a Scrum Master) that worked towards the goal set by the founders.

Creating a secure, fast, and reliable blockchain suitable for building a decentralized cryptocurrency exchange is challenging. However, accomplishing this under time pressure, with a roadmap that is behind schedule from day one, requires exceptional management skills, expertise, and an extraordinary team effort. Thanks to our dedication and years of experience in fintech software development, we were more than up to the task.

Business solution

We’ve quickly built a partner relationship with the client. Thanks to that, we were able to take full product ownership and responsibility for the product development success. That way, we were able to move fast, solve most of the problems locally, and, as a result, deliver a reliable solution on time.

The team took complete ownership of the technical aspects of the product, from backlog formulation to software delivery and technology selection. The core of the product is an innovative, built-from-the-ground new Blockchain – EXCC – with Proof of Work and Proof of Stake consensus algorithm and the entire infrastructure required for it to operate.

We created a new Blockchain and the entire infrastructure around it, including: 

  • Wallets
  • Mining Software
  • Mining and Staking Pools
  • Blockchain explorers.

Product and main features

  • Proof of Work: Equihash (ASIC-resistant) algorithm that works with Proof of Stake consensus to make Blockchain utterly secure from day one, even in the absence of computing power used for mining.
  • Infrastructure: Setup of the entire blockchain-related infrastructure (blockchain explorer, staking pool, mining pool, miners, etc.).
  • Creation of a new full node wallet – web and desktop ready.

We used to work in a very fast and dynamic way, and made decisions quickly, based on data and research. We found out quickly that often software development teams aren’t so dynamic in the delivery of the agreed scope. We contacted and tested the cooperation with a couple of them. Finally, we found the perfect match – Pragmatic Coders.
