 Although in its infancy, Solidity has had widespread adoption and is used to compile the byte-code in many Ethereum smart contracts we see today. There have been a number of harsh lessons learnt by developers and users alike in discovering the nuances of the language and the EVM. This post aims to be a relatively in-depth and up-to-date introductory post detailing the past mistakes that have been made by Solidity developers in an effort to prevent future devs from repeating history.
