Scaling a crypto app with 800+ APIs

The client faced increasing challenges as the crypto ecosystem rapidly evolved. New exchanges, blockchains, and financial products were launching almost every day, and users expected quick integration to report their income accurately and stay tax-compliant.

Falling behind on these integrations posed a serious risk to the business, leading to potential customer churn, loss of trust, and compliance issues. That’s why building and maintaining a reliable, scalable integration system became a top priority.

This meant not only adding support for new platforms, but also keeping up with frequent API and data format changes from major players like Binance, Coinbase, Bybit, and OKX.

third-party integrations

To ensure full data coverage across all platforms, regardless of their technical limitations, we developed support for both API-based and file-based integrations.

When platforms offered reliable public APIs, we built automated pipelines using Ruby on Rails to ensure accurate and timely data imports. Where APIs were missing or incomplete, we developed robust CSV parsers capable of handling messy formats and edge cases.

This flexible integration model allowed us to support a wide range of platforms and guarantee accurate income reporting for every user.

platform maintenance

With dozens of complex integrations and more coming, we needed to keep the system stable and make future integrations easy to add. This required a reliable codebase, as even small bugs could cause broken imports, bad data, or compliance issues.

We introduced a rigorous peer review process for all integration-related code, checking each update for accuracy, performance, and consistency.

This helped us maintain a stable, scalable platform that kept pace with the fast-changing crypto ecosystem.
