Multiblock MEV opportunities & protections in dynamic AMMs
Maximal Extractable Value (MEV) in Constant Function Market Making is fairly
well understood. Does having dynamic weights, as found in liquidity boostrap
pools (LBPs), Temporal-function market makers (TFMMs), and Replicating market
makers (RMMs), introduce new attack vectors? In this paper we explore how
inter-block weight changes can be analogous to trades, and can potentially lead
to a multi-block MEV attack. New inter-block protections required to guard
against this new attack vector are analysed. We also carry our a raft of
numerical simulations, more than 450 million potential attack scenarios,
showing both successful attacks and successful defense.
