Hello everyone,

although there are a few research papers on MEV on L2s ([here](https://www.arthur.bagourd.com/wp-content/uploads/2023/07/FRP_24_Quantifying_MEV_On_L2s-1.pdf) and [here](https://timroughgarden.github.io/fob21/reports/r11.pdf)), I couldn’t find any research on the MEV impact of latest Optimism upgrade, where the FCFS sequencer was replaced by a gas fee market with base/priority fees (EIP-1559) and a private mempool ([OP Docs](https://community.optimism.io/docs/developers/bedrock/differences/#mempool)).

To close this gap, I wanted to open a new FRP to analyze and quantify MEV on networks using the upgraded OP Stack (Optimism, Base). In case I’m missing something here, I first wanted to hear your thoughts whether this kind of research is interesting for the community.

Your feedback is very much appreciated!
