Introduction
Exchange Coin (EXCC) set out to build a decentralized cryptocurrency exchange (DEX) for semi-professional traders. The platform had to enable seamless and secure multi-blockchain transactions. To make this possible, we created a new blockchain that combined Proof of Work with Proof of Stake algorithms.
Business challenge
After a successful ICO, EXCC founders struggled to find a reliable technology partner for advanced blockchain development. Pragmatic Coders provided a dedicated cross-functional product team. It included blockchain, backend, and frontend developers, as well as a Product Owner and a Scrum Master.
Building a secure, fast, and reliable blockchain is already a challenge. Doing so under time pressure, with a roadmap delayed from day one, required exceptional management, technical expertise, and teamwork. Thanks to our dedication, years of fintech experience, and proven track record in developing trading software, we rose to the challenge.
Business solution
We quickly built a strong partnership with the client. This allowed us to take full product ownership and responsibility for development success. As a result, we moved fast, solved most issues locally, and delivered a reliable solution on time.
Our team managed every technical aspect of the product, from backlog creation to technology selection and final delivery. At its core, the product is a brand-new blockchain — EXCC — built from the ground up with a hybrid Proof of Work and Proof of Stake consensus algorithm, along with the full infrastructure needed to run it.
The infrastructure included:
- Wallets
- Mining software
- Mining and staking pools
- Blockchain explorers.

Product and main features
- Proof of Work: Equihash (ASIC-resistant) algorithm combined with Proof of Stake. This ensured the blockchain was secure from day one, even without significant mining power.
- Infrastructure: Full setup of blockchain infrastructure, including explorer, staking pool, mining pool, and miners.
- Creation of a new full node wallet, ready for both web and desktop.

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.
