Watch the mempool come to life
Mempool Explorer
Blocknative's Mempool Explorer constantly captures, normalizes, and enriches in-flight transaction data. Customize a visual data stream to monitor and act on transactions you care about in real-time.
Mempool API & SDK
The Mempool API & SDK makes mempool data easy to build with and integrate. By using webhooks you'll get near real time notifications of Ethereum transaction state changes when and where you want them.
Gas Platform
Gas Platform harnesses our real-time global mempool data infrastructure to accurately and consistently estimate Ethereum transaction fees. This provides builders and traders with an up-to-the-moment ETH gas fee API.
Transaction Simulation
Know what will happen in the next block by computing the complete outcomes of pending transactions. Transaction Simulation helps make existing strategies more profitable and enables new classes of trading strategies.
Integrate the mempool.
Easily integrate the mempool into your code, website, and dapps through our fully programmable and proven API and SDK.
Designed from the ground up to be composable, the most robust Ethereum transaction builder is at your fingertips.
The mempool is often characterized as a dark forest
a mysterious place full of unexpected events and adversaries. After submitting a transaction you wait, and (hopefully) it gets confirmed. Or it fails. Or it gets stuck. Or it just disappears. Why? Because your pending transaction is invisibly competing with tens of thousands of other pending transactions for limited block space.

Thanks to @blocknative, Ethereum now has it's own Mempool explorer!
The infrastructure supporting Ethereum is maturing!
Teams can now get notifications in their Slack/Discord about contract events, even before the transaction gets included!

The rise of MEV brings big challenges in how to defend yourself in the dark forest. Blocknative's new Simulation Platform is a big step forward for protocols and traders - it simulates the entire mempool in real time to help guard against malicious txs and spot profit opps.
Traders
Monitor your hot wallet for instant transaction updates, send those updates to slack or discord, and more.
Degen
Detect when liquidity begins to move in or out of a protocol, monitor top yield farming accounts, and more.
Liquidity Providers
Be the first to know when liquidity begins to move in or out of a protocol — before it is confirmed on-chain.

"Fast and reliable access to mempool data is an indispensable part of blockchain infrastructure for trading, research, contract execution, compliance, and more. But the difficulty in global node operations, network optimization, and mining pool collaboration necessitates a dedicated, expert solution. We are long-term users and partners of Blocknative and thrilled to be part of this round to explore even more usage of mempool data.”
