Zerion launches Streams for real-time onchain data delivery via Apache Kafka

Zerion just rolled out a product that says a lot about where crypto infrastructure is headed. Zerion Streams delivers real-time onchain data, specifically transactions and price updates, over Apache Kafka to enterprise teams that need it piped directly into their backends.

What Streams actually does

For anyone not familiar with Apache Kafka, think of it as a high-speed conveyor belt for data. It’s the same technology that companies like LinkedIn and Netflix use to process millions of events per second. Zerion is now using it to push onchain data, transactions and prices, to enterprise clients in real time.

In English: instead of your system asking “anything new?” every few seconds (and getting rate-limited for its trouble), Kafka pushes new data to you the moment it exists. The difference matters enormously when you’re running trading systems, compliance monitoring, or portfolio tracking at scale.

The product builds on top of Zerion’s existing API infrastructure, which already serves as the data backbone for notable names in the industry. Uniswap and Kraken are among the platforms that rely on Zerion’s API for portfolio, transaction, and DeFi position data. Streams essentially takes that same data layer and makes it continuous rather than request-based.

Zerion’s platform currently integrates with more than 8,000 protocols across over 51 blockchain networks. An enterprise client doesn’t need to set up individual data pipelines for each chain or protocol. They get a unified feed covering the vast majority of the onchain landscape.

Zerion’s broader push into developer and enterprise tooling

In May 2026, the company announced the Zerion CLI, an open-source command-line tool designed specifically for AI agents. The idea is that autonomous systems, not just human traders, increasingly need to interact with onchain data.

The company’s funding history supports this trajectory. Zerion raised $12.3 million in a Series B round led by Wintermute Ventures back in October 2022, following an $8.2 million Series A in 2021.

On the consumer side, Zerion’s generative NFT project, Zerion DNA, has accumulated over 369,000 holders.
