Simulate Transactions In-App
Capture, normalize, and enrich in-flight transaction data for unmatched data coverage and sub-transaction resolution.
Notify Users in Real-Time
Powered by our mempool API, we radically simplify integrating live transaction event data streams into your dapp. We capture every state change for every transaction, including pending, stuck, failed, dropped, sped up, cancelled, and confirmed.
Globally, in real-time, and 24x7.

Simulation Platform
Search with an edge. Our rm computes the complete outcomes of pending transactions, helping searchers know what will happen in the next block.
This can make existing strategies more profitable. It can also enable new classes of searching strategies.
Reduce transaction anxiety with in-app simulations
Blocknative's Transaction Simulation Platform uses our state-of-the-art mempool platform to allow your users to simulate unsigned transactions.
Users can preview expected net balance changes and gas fees on their connected wallets before authorizing the transaction.
Leave the heavy lifting to us by simulating the proposed transaction on Blockantive's dedicated simulator nodes based on current block height.
Protect your users from front-running
Integrate the ability for users to send private transactions within your dapp with a few lines of code. Give users peace of mind that they won't be front-run or sandwiched.
Save users money in transaction fees
Blocknative’s Gas Platform is the industry’s most accurate gas prediction tool.
By predicting gas fees based on real-time data and predictive modeling using our global mempool infrastructure and existing machine learning pipelines, there is a 16% average reduction in max fee for your users.
"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."
"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."
The stakes – and the risks
include the time to settle, transaction fees, the terms of settlement, and more.
