Confusion in the "Fund me project "

[sutirthapaul17]

In the Solidity interface lecture , what is the aggregatorv3interface doing , why we imported that , and what is it's benefits

[EngrPips]

Interfaces generally are used to define the functions available on the contracts of the interface type, and when we import them in contracts like that, we either use their type for some variables or we wrap some contract address in them to make a function call.
