Introducing the Open Source MEV Simulator

The article announces an open source MEV simulator for modeling attacks like sandwich attacks and running local experiments. Its illustrative scenario compares a trader submitting about $3,000 per swap, three times a week for a year, on a public mempool versus an encrypted or private one, using a simulated Uniswap V2 pool. In the simulation, the public-mempool trader lost $12,406 more than the private trader over the year, about 2.65% of the $468,000 volume, or $79.53 per trade. The article stresses that this model is simplified and that its 100% sandwich rate and absence of gas costs make it unrealistic, estimating 1–3% of volume as a more realistic range.
