Security Testing

Luxy App Security

Client:Luxy

Cyrex partnered with Luxy to conduct white box penetration testing across its NFT marketplace, securing minting flows, wallet management, and REST APIs to strengthen platform integrity and user trust.

The Challenge

Securing an NFT Marketplace Built for Scale

Luxy operates as an eco-friendly NFT marketplace enabling creators to mint, list, and sell digital collectibles. With blockchain integration at its core, the platform manages asset ownership, wallet interactions, and transactional logic across both frontend and backend systems.

For Luxy, security was foundational to maintaining trust among creators and collectors.

The platform required validation across:

NFT minting and transaction flows
Wallet management systems
User authentication and credential handling
REST API endpoints
Frontend and backend integrations

In NFT ecosystems, vulnerabilities can impact asset ownership, transaction integrity, and user data protection. Luxy engaged Cyrex to perform a structured security assessment capable of identifying weaknesses before platform growth introduced additional risk.

The Cyrex Solution

White Box Penetration Testing Across Marketplace Infrastructure

Cyrex conducted comprehensive white box penetration testing, reviewing Luxy’s internal architecture and application logic with full visibility into system implementations.

This approach enabled deep analysis of both backend services and user-facing components.

Backend & Frontend Security Assessment

Our engagement included detailed review of:

Entire backend infrastructure (REST APIs)
Frontend application logic
API validation mechanisms
Data handling and authorization flows

We evaluated whether NFT-related actions were properly validated server-side and resistant to manipulation.

Core NFT Marketplace Feature Testing

Within scope, Cyrex assessed key platform features, including:

Buy, sell, and mint NFT flows
Authentication and registration systems
Collection management functionality
User profile and credential management
NFT browsing and marketplace navigation
Wallet management and transaction handling

Each component was tested for improper trust assumptions, input validation issues, and logic flaws that could compromise digital asset security or user accounts.

Regression Testing & Ongoing Stability

To ensure security resilience over time, Cyrex conducted structured regression testing. This validated that new platform updates or feature changes did not introduce unintended vulnerabilities.

Regression testing reinforced the stability of previously remediated components and maintained a consistent security posture as the platform evolved.

The Outcome

Reinforced Marketplace Integrity & User Confidence

Identification and remediation of vulnerabilities across minting and transaction flows
Strengthened wallet and account management security
Improved API validation and backend integrity
Increased confidence in marketplace stability
