Overview

Welcome! This page provides an overview of Covalent and what makes our API unique. If you have any questions along the way, we have a strong community on Discord eager to help.

What is Covalent?

Covalent provides a unified API to bring full transparency and visibility to assets across all blockchain networks. Simply put, we have a single API which allows you to pull detailed, granular blockchain transaction data from multiple blockchains with no code.

What makes Covalent unique?

There are many elements of the Covalent which make us unique in the marketplace. However, our core differentiators from projects like the Graph are:

1. Data availability

We are the only project to fully index entire blockchains – this means every single contract, every single wallet address, and every single transaction. This is billions of rows of data and terabytes of data. Other projects only provide a small subset of the available data or only start collecting data once the appropriate query or filter is set up.

2. Composability

Composability is a critical piece of Decentralized Finance (DeFi) applications and allows developers to quickly and easily construct financial solutions leveraging 'Lego-like' building blocks from a multitude of projects. The multichain flexiblity and deep, granular data provided by our APIs means developers can quickly and easily build scalable and data rich applications with no query code.

3. Multi-blockchain support

Multichain is in our DNA. Covalent already indexes and has customers on 7 different blockchain networks with many more to announce soon.

4. No code solution

We believe in no-code solutions for our users. This means no complicated SQL queries, no subgraph development and maintenance, and no need to invest in highly-skilled (read expensive) developers to simply retrieve blockchain data, which is a monumental waste of engineering time. One API and you are done.
