Welcome to Group 2 Gas optimization discussions!

[blewater]

👋 Welcome, Groupmates!

We’re using Discussions to discuss specific optimizations with our groupmates. Remember that all Discord group chats are open to all group members.

Discuss any specifics and ideas you have using this forum alone.

Present optimization status

• Address the elephant in the room 😀 We are not breaking the rules as posted in the README.md This exercise is about thinking out of the box as much as about technical prowess and teamwork.
• I believe I carried all the high-level Solidity optimizations I could find if you can identify more, power to you!
• Replacing the admin checking looping with an if statement increases the deployment costs by thousands and the runtime cost savings are minimal.

Suggested optimization ideas to work on next

• Replace simple Solidity functions with Yul, i.e., balanceOf
• Replace all or most of the contract with Yul or Huff 🥷
• Yours?

Suggested workflow

• For tracking gas cost optimizations, we'll post the latest gas score in a discussion post here rather than Discord.
• Clone the repo and try your ideas; anything that lowers the gas cost successfully is a win.
• Once you identify a successful optimization, open a Pull Request to review and merge.
• If pull requests are challenging for you (which shouldn't be in our course 😃) post your well-tested change in a discussion post. Don't post in the Discord group chat

Another Solidity opt. Idea to explore: Try pinning other versions of the 0.8.x Solidity compiler other than 0.8.21 for lower gas.

I was not able to find any options to optimize the code :D It is already super minimized and actually most of the possible places I see some in-line assembly. Good job @blewater @igorroncevic. I will give it another try to think of something tomorrow morning.

I have tried changing the compiler version, as you suggested, but 0.8.0 and 0.8.1, but they increased a the deployment cost with like 20k gas. Then, tried 0.8.10 which also increased it a little. Lastly, tried the previous 2 version of the compiler, 0.8.20 and 0.8.19, but no changes in the gas.
