Engineered a Next-Gen Crypto Exchange For Canadian Client

Client Profile

Our client is a well-established blockchain-focused hardware manufacturer based in Canada. With over a decade of experience in designing and supplying custom cryptocurrency mining rigs, they serve crypto farms, institutional miners, and blockchain data centers across North America and Europe.

In 2023, with the rise of decentralized finance (DeFi) and mainstream adoption of crypto assets, the client decided to expand from hardware solutions into digital platforms—specifically by launching their own crypto exchange and wallet ecosystem that could rival the industry leaders.

Business Challenge

As crypto adoption grew among global investors, the client identified several gaps in the market:

• Overly complex user interfaces of existing trading platforms
• Lack of real-time performance and frequent platform outages
• Insecure wallets and poor admin control panels
• Fragmented mobile experiences without a unified codebase
• Limited transparency in order books and market depth

Their goal was to offer a secure, modern, and scalable cryptocurrency exchange platform that could support multiple digital assets, offer lightning-fast trade execution, and serve both novice and professional traders globally—especially across North America and Europe.

To achieve this, they partnered with Suretek Infosoft, a trusted technology partner with deep expertise in blockchain, Web3, and cloud-native product engineering.
