The global mempool data problem.

The mempool is often characterized as a dark forest — a mysterious place full of unexpected events and adversaries. And since any single node contains only a partial view of the global mempool, it is difficult and expensive to manage the mempool on your own. 


Unparalleled transaction resolution.

Blocknative's mempool data platform is fully documented and easy to work with, so you leverage real-time streaming mempool data to accelerate your project or trading strategy.

The leading global mempool data platform.

Blocknative operates a high-availability, low-latency global data platform that is purpose-built for capturing and normalizing mempool data at scale.

Providing end-to-end transaction lifecycle visibility.

Our platform captures every state change for every transaction, including pending, stuck, failed, dropped, sped up, cancelled, and confirmed. Globally, in real-time, and 24x7.

Accessible and composable via our API and SDK.

Fully documented, maintained, and supported, our mempool API and SDK radically simplifies integrating live transaction event data streams into your project or trading strategy.

Every transaction competes in the mempool. Read about how this impacted protocols and traders on Black Thursday.

"Real-time transaction notifications are critical to our user experience. After first building our own infrastructure, we appreciate that mempool management is a difficult, expensive problem to solve at scale. That's why we partner with Blocknative to power the transaction notifications in our next-generation wallet."

"Integration with Blocknative was incredibly simple. In two days, we were in production and have not had a single issue since. Now our investors can see the real-time status update of their funding and investment transactions – regardless of  whether they’re using MoonPay, Uniswap, or Wyre – and we're able to keep our transaction database in perfect sync with what happens on the blockchain."
