Covalent Partner Spotlight - Matcha (by 0x)

May 13, 2021

We caught up with Alex Kim, software engineer at 0x, to see how they are using Covalent’s API to help with the development of their Matcha product. Here is what he had to say about Covalent’s API.

Q: Can you explain the product?

Matcha is a simple decentralized crypto exchange designed for everyone! After nearly 3 years of building the 0x protocol and enabling others to build great DeFi products, our team had a ton of new ideas for how we could make it easier for more people to access exciting new markets.

Q: What use case(s) does the Covalent API help you solve?

Covalent provides the transactional data, including historical and granular, as well as a user’s token balances, and transaction history for the 0x Matcha UI. Also, rather than building support for multiple blockchains in-house, we use the Covalent API to enable Matcha supporting Avalanche, Matic, BSC, Fantom, and any other blockchain which Covalent supports. This not only save us engineering resources but facilitates Matcha adopting a multi-chain strategy.

Q: What end points are you using?

Mostly Class A end points as well as multi-chain functionality, but more specifically:

With regard to querying multiple blockchains, it is just a matter of updating the chainID parameter.

Here is what the production grade product looks like:

Q: In your own words how do you feel Covalent is helping power your project?

Covalent provides critical data infrastructure for 0x allowing us to ship faster due to less time spent on blockchain data engineering, ultimately allowing us to better serve our millions of users.

All of the endpoints mentioned above and used by 0x can be found below.

About Matcha & 0x

0x is a protocol for decentralized exchange on Ethereum allowing users to exchange tokens without a central broker — ending the many inefficiencies of centralization by enabling transparent token exchanges between contracts.

Matcha is a leading crypto trading platform powered by the 0x API. Matcha is a decentralized exchange (DEX) aggregator, meaning that users can trade across all the major decentralized Ethereum and Binance exchanges in one simple and easy to use user interface . On Matcha, users swap their tokens directly peer-to-peer without ever having to give custody of their tokens to a middleman. Matcha pools liquidity across all the best exchanges including Uniswap, Sushiswap, Pancakeswap, and more, and can even split orders across multiple exchanges to ensure that users know they are getting the best prices on the market.

About Covalent

Covalent leverages big-data technologies 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 pain-stakingly 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.
