To ensure compliance with OWASP standards, sensitive data categories in fintech apps require special attention. While Flutter allows local data storage, the safest approach is to use native iOS and Android storage systems. We achieved this by embedding native code using MethodChannel, enabling our cross-platform team to swiftly deliver a secure application that meets OWASP requirements.


Using native code to handle sensitive data with care

To ensure app security and compliance with industry regulations, we conducted mobile penetration testing (pen-testing) recommended by OWASP. As one of the first Flutter banking apps, Nextbank used both native and cross-platform libraries. Our recommendation included pen-tests and security audits, confirming compliance. The assessment validated our team's expertise in clean software architecture, data encryption, multi-factor authentication, and code obfuscation.


Pen-testing and external cybersecurity audits

To ensure scalability and adaptability, our design team prioritized building a design system as the foundation of the project. This system included UI components, typography, colour palettes, and visual design guidelines. For Nextbank, we focused on minimalist UI elements with a default theme of white and blue. To enhance the user experience, emojis were utilized to highlight banking features in the app's dashboard.


Cohesive design system

By implementing the design system in the white-label app, Nextbank's clients can easily customize the mobile app to align with their brand design. Miquido's minimalist white-label application allows banks to personalize key branding elements like colors, fonts, and shapes, as well as add logos, illustrations, and icons. The design system ensures a consistent visual identity and streamlines the process for designers and developers to create new products and features efficiently.


Designing for scaling

Nextbank has become a trusted fintech leader in Southeast Asia. They prioritize cybersecurity with regular risk assessments, including penetration testing, AST, security scanning, and audits, ensuring compliance with security standards.


Security confirmed by external IT security audits

Miquido chose Flutter for cross-platform efficiency and scalability, benefiting from native platform capabilities. With Google's ongoing improvements, Nextbank gains performance, integration, and developer experience enhancements with each Flutter update.


Native-like performance

Through cooperation with Miquido, Nextbank optimized costs in developing and maintaining the white-label Flutter app and delivering customized banking apps. A minimalist design and modular features enable Nextbank to create personalized banking apps in around 10 weeks. This scalability and cost-effectiveness have contributed to Nextbank's growing popularity in the banking sector.


Cost-effective design, development and maintenance
