Secure and Compliant Crypto Exchange Platform

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.
. Partner APIs: End-to-end APIs enabling partners like Amotius to automate onboarding, deposits, withdrawals, and trading.

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.
