Introduction

Alphadex is a decentralized finance (DeFi) technology provider that aims to empower users with comprehensive analytics and tracking tool for decentralized exchanges (DEXs). Its vision is to deliver an advanced, cross-chain Automated Market Maker (AMM) protocol with robust interoperability and an enhanced user experience.

Challenges

Alphadex aims to provide real-time token price tracking, live charts, price alerts, a pair explorer, and a new pairs scanner. However, several challenges stood in the way of achieving this goal:

– Real-time data acquisition and processing: Sourcing and processing high-volume, low-latency data from various decentralized exchanges (DEXs) presents significant challenges. This includes managing the sheer volume and velocity of blockchain data, ensuring data consistency across multiple sources, and addressing potential latency issues inherent in distributed systems.

– Scalability for high concurrency: The nature of real-time analytics and tracking for DEXs implies a need to handle a large number of concurrent users and continuous data streams. As a result, scaling the backend infrastructure to maintain performance and responsiveness under heavy load is crucial

– Efficient alerting and notification system: Implementing a reliable and efficient price alert system requires real-time monitoring of price changes and the ability to trigger notifications instantly, without overwhelming the system or causing delays.

Solutions

To overcome the challenges, Hola Tech adhered to the best practices. Key components of the solution included:

– Optimized real-time data pipeline: Develop a highly optimized data pipeline leveraging Raydium SDK for efficient data acquisition from DEXs. Utilize Redis for high-speed caching and message queuing to handle the ingress of real-time data, and implement robust data transformation and aggregation processes to ensure data consistency and accuracy.

– Horizontal scaling and load balancing: Implement a horizontally scalable architecture for the NestJS backend and Socket.IO servers using Docker and PM2. This involves distributing the load across multiple instances, configuring Redis as a Socket.IO adapter for inter-process communication and efficient message broadcasting, and utilizing load balancing strategies to ensure optimal performance and high availability.

– Asynchronous processing with Bull Queue: Utilize Bull Queue for managing background tasks such as complex chart calculations, historical data processing, and sending price alerts. This offloads computationally intensive operations from the main application thread, ensuring the real-time core functionalities remain responsive.
