  Maximal Extractable Value (MEV) has become a critical issue for blockchain
ecosystems, as it enables validators or block proposers to extract value by
ordering, including or censoring users' transactions. This paper aims to
present a formal approach for determining the appropriate compensation for
users whose transactions are executed in bundles, as opposed to individually.
We explore the impact of MEV on users, discuss the Shapley value as a solution
for fair compensation, and delve into the mechanisms of MEV rebates and
auctions as a means to undermine the power of the block producer.
