Advanced Solidity: Understanding and Optimizing Gas Costs

What you’ll learn
Learn how the Ethereum Virtual Machine sets the gas price
Learn how to improve the gas price of existing code
Learn how to debug execution costs for smart contracts
Learn what designs to avoid that lead to high execution costs

Requirements
Basic understanding of solidity
Ideally, created an ERC-20 or ERC-721 token before

Description
Ever been surprised by the gas costs in a smart contract? The Ethereum Virtual Machine calculates these costs deterministically, but understanding how is a bit obscure unless you want to comb through the dense yellowpaper! This course helps you understand where every last bit of gas is coming from and the gotchas that can make transactions surprisingly expensive.

This course is for solidity developers looking to progress from beginner to advanced intermediate. Knowledge about Solidity, OpenZeppelin, and Remix is assumed. You should know how to deploy and test a smart contract, and ideally, you’ve created a token on the mainnet before (and experienced how expensive it can be!).

I’m the author of ERC1155D, arguably the most efficient NFT contract created. I’m here to share my learnings with you!

Some of the most enjoyable years of my life was teaching computer science at Columbia University, so I’m happy to relive those years virtually!
