We run our own nodes, parse and process all data in-house, and have thorough monitoring and alerting of all our systems.

#### **Quality Data**

Data quality is our highest priority. In order to ensure first-grade data, all our metrics undergo a rigorous QA procedure by our in-house data team before being deployed to production.

#### **Cutting-Edge Metrics**

With the right metrics, blockchain data can provide insights that go far beyond simple aggregate statistics. By applying state-of-the-art methods from data science to extract patterns and trends, we provide contextualised and highly curated insights.
