Professional working with technology to address challenges

Challenges We Addressed

Technical Challenges

Handling multiple user states (unverified, partially verified, fully verified) with conditional access to platform features.

Testing complex transaction workflows, such as crypto-to-fiat conversions and vice versa, which required real-time validation.

Ensuring seamless integration testing across a variety of third-party services, including KYC providers, payment processors, and wallet services.

Operational Challenges

Managing and validating user access based on varying verification levels.

Validating the accuracy of complex, real-time crypto-to-fiat transaction processes.

Coordinating integration testing with external services to ensure end-to-end functionality.

Guaranteeing data consistency and UI synchronization, particularly for wallet recovery and transaction histories.

Why It Mattered

Ensuring a secure, reliable trading experience was crucial for user trust and platform growth. Our testing strategy reinforced platform integrity and performance.

Our Solution for the Client

To address the challenges, we implemented a strategic, multi-faceted QA framework designed to enhance test coverage and streamline the release cycle. Our solution provided a structured testing methodology that integrated seamlessly with their agile development process.

Our Approach:

Focused on delivering end-to-end test coverage for all core user journeys, from initial sign-up to verification, trading, and fund withdrawal.

Our team designed modular and reusable test cases to handle dynamic user flows, particularly for the complex KYC and wallet restoration processes.

Implemented and consistently maintained comprehensive regression test suites and a staging smoke test checklist to ensure ongoing stability.

To stay aligned with the agile development environment, we maintained active daily syncs with the development team, allowing for rapid adaptation to evolving features.

Our Trusted Clients

Before vs After

Metric	Before	After
Test Suite Coverage	Only ~40% of the application was covered, leaving critical financial workflows and user states untested and vulnerable to bugs.	Coverage was expanded to 85%, encompassing core user journeys, edge cases, and complex integrations for comprehensive risk mitigation.
Critical Bugs in Production (Monthly)	An average of 8-10 critical bugs reached production each month, requiring urgent hotfixes & eroding user confidence in the platform's reliability.	The number of critical bugs was reduced to just 2-3 per month, resulting in a significantly more stable platform and increased user trust.
Regression Cycle Completion Time	Regression testing was a major bottleneck, taking 2 full days to complete, which significantly slowed down the entire development and release pipeline.	The regression cycle was optimized and streamlined, reducing the completion time to just 1 day, enabling faster and more frequent releases.
Manual Testing Time (Per Cycle)	Each testing cycle required approximately 12 hours of manual effort, consuming significant QA resources and increasing the risk of human error.	Through better test case management and a structured approach, manual testing time was reduced to ~7 hours per cycle, freeing up the team.
