Everything is stored in **ClickHouse (only order books are stored in CSV)**, so historical queries and aggregations are executed **very fast**. An important point: the solution is **unlimited** — history is not truncated and there are no limits on the number of requests; you work with the full dataset. For **on-chain analysts**, this is a convenient way to link wallet activity with markets and events: who traded and how, how liquidity/spreads changed, how the market reacted to resolutions. For **ML engineers** and **algo traders**, the value lies in the complete set of trades and tick-level order book data: you can reconstruct the order book over time, calculate microstructure features, and run backtests on the full history without bottlenecks in data extraction speed. For **service builders** and traders, this is a foundation for products: dashboards, alerts, signals, wallet scoring, and risk metrics. Compared to solutions based on public APIs, you get more control, a stable data schema, and significantly faster analytical queries — while the system scales to any volume. ### **How To Get Access** **The cost is $200 per month, and we provide a free 7-day trial** so you can calmly test everything and make a decision. We will create a separate chat with you, show everything, explain everything, and provide individual technical support. **For any questions, you can contact us:** [**https://t.me/inventandchill**](https://t.me/inventandchill) #### Research Blog **Check out our research blog, where we publish research articles with examples using data from our indexer:**\
