Solidity Tutorial: Built-in Variables (msg.sender, msg.value…)

Solidity Tutorial: Built-in Variables (msg.sender, msg.value...)

Register to the FREE mini-course “become a blockchain developer” on to learn how to get a remote blockchain job making 100k. (Like I did myself).

Built-in variables are Solidity variables that allow you to get information about your environment: the calling address, the amount of Ether sent in the transaction, etc…

In this video I am going to show you the most useful Solidity built-in variables.
