Introduction
At Techtion, we developed Nebula Payments from the ground up—initially as a simple record-keeping application for both crypto and fiat transactions. Over time, the platform evolved into a full-fledged cryptocurrency exchange serving both organizations and direct customers.
As user demand increased and regulatory requirements became more complex, Nebula Payments engaged Techtion to deliver major platform upgrades. The goal was clear: ensure full regulatory compliance, improve scalability, and provide an end-to-end automated experience—from user onboarding to transaction settlement
Key Challenges & Solutions
1. Manual Process
Challenge
Transactions were recreated manually, and KYC reviews relied on Google Drive for document storage. This required supervisors to perform multiple manual checks, increasing errors and slowing operations.
Solution
Techtion integrated Sumsub for KYC verification, automating the entire onboarding and transaction workflow. All documents and verification data are now stored in a centralized system—significantly reducing errors and freeing up supervisory resources.
2. Regulatory Complaince
Challenge
Nebula Payments needed to comply with Australian Anti-Money Laundering (AML) regulations. Accepting fiat deposits required a transparent, fully traceable process aligned with local laws.
Solution
We integrated an Australian banking system that automatically generates dedicated bank accounts for each user’s AUD deposits. This ensured full traceability, proper documentation, and AML compliance across all fiat transactions.
3. Growing Partner Ecosystem
Challenge
As Nebula Payments onboarded partner organizations such as Amotius, it required seamless APIs to support user registration, KYC workflows, fiat deposits, crypto wallet creation, and end-to-end trading.
Solution
Techtion designed a robust, API-driven Node.js architecture, enabling partners to access Nebula Payments’ full capabilities—from onboarding to transaction execution—without building their own payment infrastructure
4. Limited Scalibility
Challenge
The original system architecture was fragmented and unable to handle higher transaction volumes or support rapid feature expansion.
Solution
We rebuilt the platform using the MERN stack (MongoDB, Express, React/Redux, Node.js) with a modular architecture. This allowed Nebula Payments to scale seamlessly as transaction volumes increased and new features were introduced.
Approc Methodolgy
Requirement Engineering
The Techtion team conducted detailed requirement analysis, documenting both current needs and future expansion goals. This ensured a clearly defined scope and reduced rework during development.
UI/UX Design
Using Figma, we designed an intuitive interface tailored for both novice and experienced crypto users. Multiple design iterations—driven by real user feedback—resulted in a highly usable and compliant platform experience.
Aglie Implimentation
Front Development
Built with React and Redux, the frontend delivers a fast, responsive, and multi-theme user experience across devices.
Backend Development
Backend functionality was implemented as Node.js microservices, enabling easier maintenance, better scalability, and rapid third-party integrations.
Key Integration
. KYC Automation: Sumsub integration for streamlined identity verification.
. Fiat Banking: Australian banking system integration with auto-generated AUD accounts.
. Crypto Wallets: Fireblocks integration for secure wallet creation and transactions.

Implimentation Highlights
End-to-End Automation
From user signup and KYC verification to deposits, withdrawals, and rolling reserve management—nearly every process is fully automated.
Rapid Delivery
Despite the platform’s complexity, Techtion delivered the core upgrades in just four months, ahead of the original timeline.
Enhanced Security
Comprehensive testing, detailed documentation, and security-first architecture ensured regulatory compliance and data integrity—critical in the crypto-financial space.
Result & Impact
Scalable Growth
The new architecture supports higher transaction volumes and additional partner integrations without performance bottlenecks.
Revenue Increase
Streamlined fiat deposits and crypto trading flows significantly increased transaction volume—directly boosting revenue.
Improved User & Partner Experience
Faster onboarding, reliable transactions, and API-driven integrations improved satisfaction for both end users and partner organizations.
Key Lessons Learned
. Ongoing Collaboration: Regular communication minimized assumptions and accelerated decision-making
. Proactive Advising: Recommending best practices—rather than simply executing requests—resulted in a future-ready platform
. Detailed Documentation: Strong documentation ensured smooth iterations and long-term scalability
Next Steps
With the core platform now fully rebuilt and automated, Nebula Payments is expanding into new markets, including the upcoming Nebula FX Portal. Techtion continues to partner with Nebula Payments to support the next phase of innovation and growth.
A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine. I am so happy.
I feel that I never was a greater artist than now. When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary.
