[Use Case] How Upbit Leveraged Nodit's Real-Time Web3 Data API for Onchain Fraud Detection

Case Study: Leveraging Enterprise-Grade Web3 Data Infrastructure for Onchain Transaction Monitoring

As blockchain-based financial activities continue to expand, access to accurate and timely onchain data has become a critical requirement for institutions responsible for transaction monitoring and risk management.

Upbit, South Korea’s leading cryptocurrency exchange, addressed this challenge by building the Onchain Tracer System (OTS) to track and analyze suspicious blockchain transactions across multiple networks.

To meet the operational demands of OTS, including real-time data availability, consistency across blockchains, and system stability, Upbit adopted the Nodit Web3 Data API, provided by Lambda256. Nodit enabled Upbit to streamline onchain data operations and improve the overall efficiency of its transaction monitoring workflows.

Challenge: Manual Tracking and Inconsistent Blockchain APIs

Upbit’s Financial Data Intelligence (FDI) team developed OTS to analyze the movement of digital assets between wallets using AI-driven models.
The system supports both deposit source analysis and withdrawal path tracking, providing actionable insights for internal risk teams as well as external stakeholders such as regulatory and investigative bodies.

However, operating OTS in a multi-chain environment presented several challenges.

Fragmented data integrations
Each blockchain required separate API integrations, increasing system complexity and operational overhead.

Limited reliability in real-time data access
Variations in data quality and response times across different providers made it difficult to maintain consistent real-time monitoring.

Solution: Streamlining Blockchain Data Operations with Nodit

By integrating Nodit’s Web3 Data API, Upbit was able to address these challenges through a more standardized and scalable data architecture.

1. Unified API Across Multiple Blockchains

Nodit provides a single, unified API that supports multiple blockchain networks, allowing Upbit to consolidate previously separate integrations into a unified operation.
This approach significantly reduced maintenance effort while improving overall system reliability.

“Previously, we had to manage APIs for each blockchain individually, which created operational inefficiencies. Nodit allowed us to consolidate these integrations into a single API, simplifying both development and maintenance.”

2. Reliable Real-Time Data with High Accuracy

For transaction monitoring systems, the accuracy and timeliness of onchain data are essential. Nodit delivered consistent real-time data performance, enabling Upbit to improve response times and operational confidence.

“We were satisfied with both the speed and accuracy of the real-time data. Nodit helped us reduce system response times and improve service reliability.”
— SHIN, OTS Project Developer

3. Enterprise-Focused Customization and Rapid Feedback

Nodit demonstrated flexibility in responding to Upbit’s operational requirements.
Through dedicate and direct communication channels, custom features such as combined wallet transaction and swap log queries were implemented efficiently.

“Nodit was the only provider that fully understood our requirements. The ability to quickly implement custom features had a meaningful impact on our operational efficiency.”
— SO, FDI Team Lead

Results: Improved Efficiency and Faster Response

After adopting Nodit, Upbit achieved measurable improvements across its onchain monitoring operations.

• Improved efficiency: The introduction of a unified API and faster data access reduced manual processing, allowing the FDI team to spend less time on system maintenance and more time on investigative analysis.
• Reduced time to action: With access to reliable real-time onchain data and improved response performance, Upbit was able to identify and respond to suspicious transactions more quickly.
• Enhanced reliability: By leveraging Nodit’s stable Web3 Data API, the FDI team gained consistent access to accurate blockchain data, minimizing service disruptions and operational uncertainty.
• Quick Response: A fast feedback loop and direct communication with Nodit’s team enabled continuous improvements to the Onchain Tracer System, supporting ongoing optimization of monitoring workflows.

Looking Ahead: Expanding Blockchain Coverage

Upbit continues to work with Lambda256 to extend Nodit’s blockchain coverage as part of its broader efforts to strengthen transaction monitoring and user protection.

“We plan to expand monitoring capabilities across additional blockchain networks. Nodit’s reliability gives us confidence as we scale our systems.”
— SO, FDI Team Lead

As digital asset adoption grows, institutions increasingly require robust, scalable, and auditable onchain data infrastructure.
This case demonstrates how enterprise-grade Web3 data platforms, when delivered with institutional requirements in mind, can support secure and compliant blockchain operations.
