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!
