About the Client
Chainglance is a cryptocurrency portfolio tracking platform built with React, TypeScript, Node.js, and hosted on AWS. The platform allows users to connect their EVM, Bitcoin, and Solana wallet addresses to automatically retrieve and analyze their blockchain data. Over the course of 16+ months of continuous development, the system has evolved into a robust solution capable of processing large amounts of on-chain data efficiently while supporting concurrent usage by many users.
The Challenge
Building a crypto portfolio tracker that could handle multiple blockchains presented several core challenges:
Multi-Chain Complexity — Supporting EVM-based wallets, Bitcoin, and Solana required integrating with diverse APIs, data formats, and consensus models.
Massive Data Volumes — Each wallet could generate thousands of transactions across multiple chains, demanding efficient storage and retrieval to avoid high infrastructure costs.
Concurrency at Scale — The platform needed to support many users running heavy queries simultaneously without downtime or slow performance.
Real-Time Tracking — Users required timely portfolio updates, notifications, and watchlists, making performance and reliability critical.
Tax-Grade Reporting — Generating detailed, exportable transaction histories that accountants could rely on for crypto tax filing in the US added an extra layer of complexity and precision.
Long-Term Development Partnership — The client needed a team capable of sustaining development and iterating over 16+ months while ensuring the platform remained stable in production.
Key Goals
We engineered an end-to-end system that:
Retrieves all relevant blockchain data for supported networks, including transactions, historical balances, and assets from various sources.
Stores this data efficiently to optimize performance and reduce infrastructure costs.
Handles high concurrency without performance degradation through advanced engineering techniques and architectural improvements.
Offers user-friendly features for portfolio and watchlist management, including notifications for address activity.
Allows users to export rich CSV reports containing all wallet transactions — especially useful for crypto tax reporting in the US.
Our Approach
Radical Online combined deep blockchain expertise with scalable software engineering to tackle these challenges:
Incremental Blockchain Integration — We built modular services for EVM, Bitcoin, and Solana, each tuned to the nuances of its network, enabling expansion without major refactors.
Efficient Data Architecture — By designing optimized data models and leveraging AWS services strategically, we reduced storage costs while ensuring queries over millions of records stayed performant.
High-Concurrency Engineering — We applied advanced techniques (job queues, streaming, caching, load balancing) to guarantee stability even under heavy simultaneous usage.
User-Centric Features — We paired backend robustness with a React + TypeScript frontend, making portfolio management, watchlists, and notifications simple for end users.
Tax Compliance in Mind — We built CSV exports aligned with US crypto tax workflows, ensuring accountants could depend on Chainglance for accurate reporting.
Agile, Continuous Development — Over 16+ months, we collaborated closely with the client, iterating quickly, shipping features in phases, and continuously improving reliability as the user base grew.
Through this approach, Chainglance became a scalable, accountant-ready crypto portfolio tracker that balances performance, accuracy, and user experience across multiple blockchains.
