Some generic writeup about common gas optimizations, etc.

Upgrade to at least 0.8.4

Using newer compiler versions and the optimizer gives gas optimizations and additional safety checks for free!

The advantages of versions 0.8.* over <0.8.0 are:

  • Safemath by default from 0.8.0 (can be more gas efficient than some library based safemath.)
  • Low level inliner from 0.8.2, leads to cheaper runtime gas. Especially relevant when the contract has small functions. For

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
