Multi-Currency Crypto Exchange & Portfolio Management App Engineering

Picking up product development to make it to a showcasing version

Client and Project Goals

An Australian FinTech industry newcomer looking to validate their business initiative and develop a competitive signature project.

Seeking to obtain a reliable and intuitive semi-private cryptocurrency trading app with market making capabilities, the client switched outsourced contractors twice in just four months of project duration. AIS Novations was selected to review the existing deliverables and do the heavy lifting needed to take the solution to a successful release.

Solution

The solution is a multi-currency online web app intended to help users with little crypto exchange experience easily enter the market. To enable handling as many digital currency deals as possible, the app utilizes a universal token-powered USDT coin for transaction execution.

Highlights

Built-in matching engine and portfolio tracking
Integration with Bitfinex exchange
10 major cryptocurrencies support (BTC, ETH, and more)
Crypto-to-fiat and vice versa trade

Work done

Software requirements specification with detailed user stories and crypto order mechanisms
User interface elements development
App demo version fine-tuning

Major modules

Customer interface (UI)

Enables users to create orders, visualize and manage their digital currency portfolio.

Market maker

Helps create virtual exchange liquidity orders, generate volume, and pull live order books for external exchanges APIs.

Matching engine

Allows matching buy and sell orders, creating transactions, and updating client account balance.

Admin interface

Allows managing fiat withdrawal requests, verifying user IDs, and starting transactions.

Crypto client interface

Supports digital currency activities, enables exchange of crypto assets with third-party wallets.

Challenge

While validating the project’s initial tech stack and testing deliverables, AIS Novations team discovered several critical discrepancies. The toolkit chosen by previous vendors put the solution’s functional feasibility into question, with code aching for end-to-end refactoring and patching.

In need of discussing further steps with the project’s stakeholders, the client took their time and paused the development for an uncertain period.
