Solidity developers are spoilt by the number of 3rd party protocols we can connect to. From within our code we can make calls to external contracts to carry out tasks such as swapping tokens or depositing into a yield farm for example. To make these external calls we use interfaces and in this tutorial we are going to go through some examples of common interfaces and how to use them.
