MEV Supply Chain: Trust but Verify
Private mempools promise MEV protection. But without access to private data, how can we be sure they’re protecting users? Our research proposes a new method using onchain data to verify private mempools aren’t taking advantage of users.

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.

@nero_eth tweeted...“ 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.

Ethereum Mempool Dashboard
The mempool, also known as the txpool, is essentially a collection of pending transactions that each Ethereum node maintains locally. Unlike a single, universal mempool containing all unconfirmed transactions, each node has its own unique set of pending transactions.
