Covalent leverages big-data technology to create meaning from hundreds of billions of data points, delivering actionable insights to investors and allowing developers to allocate resources to higher-utility goals within their organization.

Instead of painstakingly sourcing data from a small handful of chains, Covalent aggregates information from across dozens of sources including nodes, chains and data feeds. The Covalent API then sources end-users with individualized data by wallet, including current and historical investment performance across all types of digital assets.

Most importantly, Covalent returns this data in a rapid and consistent manner, incorporating all relevant data within one API interface.

A one-stop-shop for the most granular, multi-chain data with one API

Covalent has indexed and decoded entire blockchains, including every single smart contract, user balance and position, and more, allowing easy access via a unified API.

Covalent believes in a multi-chain future and currently provides the richest data for the multiple blockchains. See the full list of supported blockchains along with network-specific details.

Data transparency and accessibility with no-code solution

The Covalent API is the easiest way to access on-chain data from different chains—simply change the chainId when making a call to an API endpoint. There is no need to write a subgraph or custom SQL queries and all data is immediately available.

Additionally, API calls can be made directly from within the Covalent API docs with the response in CSV format so anyone can easily export the data into Excel, Google Sheets, PowerBI, Tableau or any tool of choice for analysis and presentation.
