This project involves building a Mobile App for a Crypto Exchange platform based on the pre-existing API platform. The mobile app is required to have all the necessary features of a cryptocurrency exchange, including integrated candlestick charts, user face recognition, and authentication for KYC, trading, deposit, and withdrawal functionalities. Additionally, the app must ensure a high-performance architecture and meet the customer’s security requirements.
Client name: Private
Mobile Application (iOS/Android)
We deployed the project with a team of experienced developers in the blockchain field, implemented a Hybrid app approach, chose the right programming languages, integrated Google Analytics & Sentry, and also applied specific security rules.
Evaluation and implementation of a Hybrid app approach
Choosing programming languages that have libraries supporting all project requirements
Involving experienced developers who have previously worked on crypto exchange platforms to enhance speed and quality
Integration of Google Analytics/Sentry to identify and handle all non-API-related errors
Implementation of specific security rules for the mobile app
The project team encountered no technical challenges, including achieving the system’s functional criteria as specified by the SEC, based on prior experience working on other exchange systems. However, the project has to face challenges due to the Cryptocurrency downtrend:
Financial Impact of Cryptocurrency Downtrend
Risk of Uncertain Market Conditions
Balancing Project Quality and operational Cost
Managing Stakeholder Expectations
Ensure legal protection for users set by the Securities and Exchange Commission (SEC)
The way we save cost and optimize quality for this project:
Developing the app using a Hybrid approach (Typically, for finance-related apps, prioritizing a consistent logic across iOS and Android reduces errors and cost, making the Hybrid approach the most suitable choice)
Rational division of work
(Developers with no prior experience with exchanges focus on UI development, while developers with exchange knowledge solely handle API integration, significantly boosting project speed and quality)
With the current capabilities of AI in assisting various tasks, applying AI to tasks such as UI design, testcase review, and source code review has helped the project team save a significant amount of time and effort.
Using SonarQube for automated code review helps save costs associated with manual code review and ensures the quality of the source code.
Each project involves both experienced and new team members. Although all team members receive training before joining the project, it is not possible to cover the entire system comprehensively. Therefore, to accelerate project progress and ensure the highest quality, it is essential to assign experienced individuals to tasks that require expertise in a specific domain. For example, when developing a Mobile App, experienced individuals can handle API integration for screens with complex logic, while newcomers can focus on UI development, requiring little or no experience in Crypto Exchange.
It may seem difficult to persuade, but usingthird-party services can save more money than handling a service internally. For instance, by using a third-party service for Slider Captcha (a service provided by a dedicated team), the project can save costs compared to implementing and maintaining a separate service. Based on the company's experience and project team's expertise, they have identified third-party providers with the best cost-effectiveness, stable service quality, and sustainability.
Each error results in a series of related actions, such as logging bugs, fixing and retesting, reporting, and capturing evidence. By ensuring strict quality processes within the company, the project team has minimized the occurrence of errors, reduced rework time and saving costs.
With their own experience and a team of experienced consultants, the project's technical and business implementations are streamlined and accurate, minimizing costs, time, and resources. For a large-scale project, even a single incorrect business or technical approach can lead to a cascade of issues. By forecasting and providing appropriate solutions based on previous project experiences, this project ensures the highest quality while maintaining reasonable and cost-effective measures.
Within less than 3 months, the team successfully completed the app for the client, meeting the set deadlines and quality standards. This achievement serves as a foundation for future projects, as the client continues to engage SparkMinds for further collaborations.
