To see all integrated data sources visit:

The data retrieval is processed through a series of asset collectors, capable of fetching all kinds of financial data. These collectors are classified into the following groups:

  • Centralized Exchange Scrapers: Collect data from centralized exchanges for cryptocurrencies and other assets (like stocks, futures, and rare earth metals) such as Binance, Coinbase or Kraken.

  • Decentralized Exchange Scrapers: Collect data from decentralized exchanges on various blockchains by subscribing to swap events in the corresponding LP pools. Examples for sources are Uniswap, curve.finance or PancakeSwap.

  • Bridge Scrapers: Collect swaps data from bridges bridging crypto assets between different blockchains. Examples of sources are Multichain, Anyswap or Hop.

Trading Data

The raw trading data is the basis of all further derived quantities such as prices and circulating supply numbers for all cryptocurrency exchanges. We retrieve and store trading data from as close to the data source as possible and with the highest precision possible.

In this section you will find information about the methodology for the following data:
