In this video, we are introducing the aeternity smart contract editor and its functionalities.

Intro to the smart contract editor

In this video, we will build our first contract that can write to the aeternity blockchain and retrieve data from it. We will also learn about the state, types and functions of our contract.  ⚠️ Update:  When you enter a string as an argument in the contract editor you no longer need quotation marks as described in the videos. Instead of “url.com”, it’s url.com.
