The MEV Letter is a weekly collection of papers, articles and resources related to MEV. The intention of this letter is to provide a comprehensive summary of the latest research, discussions, and developments in the space, with links for further reading.
Papers & Articles
- ePBS, distilled by Mike Neuder explains the key features of ePBS and describes why established builders and relays are expected to retain an advantage as bidding becomes more direct and potentially more private.
- Pre-FRP: Topological MEV Detection During Block Construction by Uri explores whether Topological Data Analysis of early transaction patterns can identify sandwich attacks while a block is still being built.
- AMM Yield Maximization: When Liquidity Providers Become Arbitrageurs by Andrei Seoev and Yury Yanovich explores how AMM hooks can rebalance pools atomically after swaps to reduce value extraction by searchers or builders and capture more value for LPs.
- Greed is good, with one exception by Hernán Erasmo reverse-engineers how an onchain arbitrage bot on Arbitrum uses golden-section search and a custom simulator to find the optimal trade size while limiting gas costs.
- Timing the Head in Ethereum PoS by Yolodannn examines how head-vote timing games can cause honest validators to lose rewards, and proposes distance-weighted head rewards to reduce losses.
- Glamsterdam Repricing Impact for Smart Contract Developers by Ethereum Foundation details the gas repricing impact on existing Ethereum L1 smart contracts when EIP-8037 and EIP-8038 are activated in Glamsterdam.
- Native Account Abstraction Does Not Need a General-Purpose Transaction Layer by Pedro Gomes compares EIP-8130 with Frame Transactions, and argues that EIP-8130 is a simpler, more predictable, and more portable account-abstraction approach for EVM rollups.
- The new AA debate — 8130 vs Frame Transactions by Derek Chiang details the trade-offs between EIP-8130 and Frame Transactions how their designs are converging, and frames the remaining choice as simpler, more structured validation with less fragmentation versus greater extensibility and account diversity.
- Post by Mislav Javor
- When Multiple Pools Behave Like One: Impact-Constrained Capacity Concentration in Uniswap v3 by Wen-Ting Wang analyzes whether multiple Uniswap v3 pools for the same token pair meaningfully increase execution capacity at fixed price-impact limits, when capacity is typically concentrated in one dominant pool.
Posts & Threads
- Chris Hunter published a post outlining the case for EIP-8130 as a portable standard for Account Abstraction, and explains how it could provide a common account model across EVM chains.
- Chris Hunter published a thread critiquing Frame Transactions, and proposes using EIP-8130’s keystore to externalize authority and reduce complexity.
- Barnabé Monnot published a post detailing Ethlabs’ work to accelerate slot times, finality, confirmations, and cross-domain interoperability without compromising security.
- EthCoordinate published a thread detailing Ethereum’s upgrade governance process and how the ACD calls can move EIPs from proposed (PFI) to considered (CFI) and eventually scheduled for inclusion (SFI).
