Covalent

Covalent is dedicated to addressing the huge infrastructure issues that stand in the way of blockchain adoption. They provide a unified API that brings complete transparency and visibility to all blockchain network assets. Its solutions connect the database world with distributed blockchain technology. The first version was built at a hackathon in fall 2017.

Covalent provides a unified API to bring complete transparency and visibility to assets across all blockchain networks. In short, we have an API that allows you to extract detailed, fine-grained blockchain transaction data from multiple blockchains without code.

There are many elements of Covalent that make us unique in the marketplace. However, the core difference between us and projects like Graph is this:

< h4 id = "1 - data - the availability" > 1. Data availability

We are the only project that has fully indexed the entire blockchain -- meaning every contract, every wallet address and every transaction. That's billions of lines of data and terabytes of data. Other projects provide only a fraction of the data available, or start collecting data only after the appropriate queries or filters are set up.

< h4 id = "2 - composability" > 2. Composability

Composability is a key part of decentralized Finance (DeFi) applications, allowing developers to quickly and easily build financial solutions using "Legos like" building blocks from numerous projects. The multi-chain flexibility and deep, fine-grained data provided by our API means that developers can quickly and easily build scalable, data-rich applications without having to query code.

< h4 id = "3 - multi - blockchain - support" > 3. Multiple blockchain support

Multiple strands are present in our DNA. Covalent has indexed and has customers on seven different blockchain networks, with more to be announced soon.

< h4 id = "4 - no - code - solution" > 4. Code free solution

We believe in providing our users with no code solutions. This means there are no complex SQL queries, no development and maintenance of subgraphs, and no need to invest in highly skilled (and costly to read) developers to simply retrieve blockchain data, a huge waste of engineering time. One API, and you're done.
