MEV Protection + Full Visibility

Real-Time Observability for Public Blockchain Networks

Public blockchains are adversarial environments, where automated predators hunt your transactions. Their hunting ground is the Dark Forest of the public mempool.

Blocknative illuminates the Dark Forest and protects your transactions. Don’t get rekt. Get Blocknative.

Real-Time Observability Gives You and Your Project:

Transparency

The pre-chain layer is ephemeral, globally distributed, and constantly in flux. Blocknative lets you see what is happening, as it is happening. 

Knowledge

Don't trust, verify.
On-chain data tells you what happened, pre-chain data tells you why it happened. Blocknative drives improved outcomes.

Protection

Intelligently route your transaction to reduce adversarial outcomes and regulatory exposure. Blocknative enables programmable settlement.

Observe and act on your transactions

See everything in one observability platform.

Transaction Explorer

Understand the past, present, and future of the blockchain. Observe how transactions move towards inclusion. 

Transaction Boost

Protect users from frontrunning and sandwiching attacks without sacrificing visibility.

Gas Platform API

Most reliable gas estimation for inclusion in the block you want.

Mempool API & SDK

Easily stream mempool events into your Dapp. Support for ETH, Matic, and xDai.

Web3 Onboard

The easiest way to support all of the top wallets and allow users to transact with confidence.

“The short seconds between when a blockchain transaction is submitted, and when it is final, is the most valuable and important moment in finance—and also the least understood. Blocknative is developing crucial infrastructure to monitor & manage blockchain transaction processing.”

The Costs of Swapping on the Uniswap Protocol

We present the first in-depth empirical characterization of the costs of trading on a decentralized exchange (DEX). Using quoted prices from the Uniswap Labs interface for two pools — USDC-ETH (5bps) and PEPE-ETH (30bps) — we evaluate the efficiency of trading on DEXs.

Quick notes on Blocknative vs Mempool Dumpster data initiatives

Blocknative (BN) Mempool Data Program and Flashbots Mempool Dumpster (MD) are two recent initiatives aimed at open-sourcing Ethereum mempool data. In this short report, we analyze and compare both datasets to highlight their key differences and foster data initiatives within the community.

“ The data for the chart was outlier-corrected mainly to account for txs laying in the mempool for hours/days, not being able to pay for the basefee, or for other any reasons. The mempool data used to capture the time delta was collected by @blocknative. ”

The False Narrative of MEV Protection

Private transactions have taken off across the Ethereum ecosystem. In the graph below you can see that private transactions have been steadily growing post-Merge from ~5% to nearly 15% of all smart contract interactions today, with a large jump around April and May. The reason for many of these private transactions is to protect users from being frontrun by MEV bots that target their transactions in the public mempool.
