The PufferModuleManager contract serves as a factory and manager contract to facilitate restaking.
PufferModuleManager is a factory contract for creating protocol-owned PufferModule and RestakingOperator contracts.
It uses the UUPS upgrade pattern to allow for future upgrades to the contract.
Both PufferModule and RestakingOperator contracts use a beacon proxy pattern to allow for future upgrades.
PufferModuleManager serves as a central contract for coordinating calls to the PufferModule and RestakingOperator contracts.
Importantly, the PufferModuleManager is the only contract with access to call RestakingOperator functions and can solely call the EigenLayer-related functions on the PufferModule contracts. This restriction is in place to allow the DAO to control restaking operations to mitigate AVS and operator risk.
