The CriptoDB project is a comprehensive data infrastructure initiative aimed at consolidating and structuring high-frequency trading and transaction data from both centralized and decentralized cryptocurrency exchanges. By integrating information from major platforms such as Binance, Bitmex, Kraken, and Uniswap, the database provides a unified and reliable source of truth for crypto market research and analytics. Built on PostgreSQL with TimescaleDB extensions, CriptoDB supports efficient storage and querying of large-scale time-series data. Its primary objective is to enable robust, empirical research on price formation, liquidity dynamics, and on-chain versus off-chain data transparency in crypto markets. Access to the database is offered via a REST API, ensuring both public usability and integration with analytical tools and automated pipelines.
The CriptoDB database is a PostgreSQL + Timescale-based platform designed to store and serve high-frequency data from both decentralized and centralized cryptocurrency markets. It provides unified access to a wide array of financial indicators, including tick-level trading activity, market depth, open interest, funding rates, and token-level transactions. Data is collected from major centralized exchanges—such as Binance, Bitmex, Deribit, Gate.io, Huobi, Kraken, and OKEx—as well as from decentralized exchanges like Uniswap, where transactional data is consolidated in a single table (erc20_transactions). The structure of the database is optimized for performance and scalability. For example, Uniswap’s data table includes indexed columns such as time_stamp, token_symbol, and hash, as well as a composite index on addresses to improve query efficiency. While most CEX data is structured by exchange and data type (e.g., intrade, intramark, open interest), DEX data is stored in a unified, normalized format to allow efficient querying and cross-platform analysis. This initial release includes all data collected up to May 27, 2025. Although CriptoDB continues to update in real time, access to data beyond this date—as well as access to the full REST API—requires prior approval. Interested parties must submit a request outlining their intended use. Data access will be evaluated based on the relevance, scope, and alignment of the application with the goals of the project. Priority will be given to research and academic initiatives. CriptoDB aims to serve as a foundational resource for empirical research on cryptocurrency markets, particularly in comparing on-chain and off-chain dynamics. A complementary Developer’s Guide is available for users seeking to deploy the infrastructure components (including Airflow and Docker) and contribute to the project.
