We built Defined for two reasons: to provide traders with the data they need to make great decisions, and to showcase the speed and accuracy of Codex’s API.

Since 2021, Defined has been a trusted source for on-chain token and NFT data, used full-time by some of the most successful traders in the world.

Defined is the best way for traders to quickly find new, popular tokens while they are still on the rise. The ability to sort transactions from descending to ascending allows users to see who the first traders are buying a new, popular token and track their trades going forward.

None of this would be possible without the speed and accuracy of Codex API's, which ensures traders using Defined get data they need to make trading decisions, immediately when they need it.

“Codex and Defined could not exist without each other. Codex provides the fastest, most accurate data, while the users of Defined consistently stress test the platform to make sure it’s reliable for Codex’s other customers”

Mike Rowe,
CEO and Founder of Defined

The challenge: Getting fast and accurate data

In late 2020, on-chain token trading was still in its infancy. Our team was frustrated with all of the existing tools, which largely provided inaccurate or incomplete data. We decided to build the charting platform that we wished existed — one that was fast enough to reliably track new and quickly rising tokens in real-time.


At the time there were only a handful of APIs that provided raw blockchain data, all of which were technically difficult to work with. None of them provided enriched blockchain data that could be easily integrated into an application, and most were slow and inaccurate with the data they did provide.

High-frequency traders care about speed and accuracy more than anything else. A charting platform with 2 seconds of latency between a transaction being confirmed and displaying on charts offers traders an enormous advantage over one with 10 seconds of latency. That advantage could be worth thousands, or even millions, of dollars to some traders.

Powering Defined with Codex

We quickly realized that if we wanted Defined to be as fast and accurate as we knew it could be, we would have to build our own API. And, Codex was born.

Building our own API gave us the freedom to meticulously structure the data and endpoints, making it easy to integrate with and parse. It has also allowed us to enrich the data with extra, valuable information that other API’s raw data lacks, such as USD pricing, real-time charts, holders data, and much more.

Since Defined doesn’t rely on third party data sources to provide critical infrastructure, we are able to build new features quickly, in-house based on user demand. This fast build-measure-learn approach helped us quickly find product-market-fit with early users and rapidly iterate the product to serve their growing needs.

Today, Defined has grown to serve over 500 million API calls a month. This has allowed us to constantly stress-test the Codex API, and resulted in both products boasting better features and more accurate data for end-users.
