# MulticallFacet

The purpose of this contract is to serve as a facet in a Diamond contract that allows for batch execution of multiple delegatecalls using the `multicall` function.

### multicall():

The `multicall` function enforces that the caller is the contract owner and then delegates the execution to the `LibMulticall.multicall` function, which handles the execution of multiple delegatecalls to different facets.
