Hey everyone, I recently came across this error "Contract code size exceeds 24576 bytes ". I googled and read a few things. There are 2 solutions that I get. 1. Using a truffle plugin. 2. Refactor code to be modular. I can't do the first one as I am using Hardhat. And secondly, I can't really refactor much here. What I have here is a governance contract that I made from reading the openzeppelin blog. I am going to make this upgradable and add features late..... I can see how to make the modular but what I have so far is just very basic/necessary. I have just imported contracts and overridden functions. That's it,there isn't really much to refactor. I have added config to help me but nothing was affected. ```auto module.exports = { solidity: "0.8.0", settings: { optimizer: { enabled: true, runs: 1 }, evmVersion: "byzantium" } }; ``` Any help or suggestion is appreciated. ---

Maybe this helps: > **[Downsizing contracts to fight the contract size limit](https://soliditydeveloper.com/max-contract-size/)** > > There is a maximum size for smart contracts to prevent DOS attacks. What can you do to prevent your contracts from getting over the limit? Generally try to remove functions you/your contract won't ever use. When copy and pasting contract code from somewhere else, you often introduce functions that never will be used. ---

Can you share the code? There are different tricks you can try depending on the code itself. ---

I have already spent some time on that but my contract is the bare minimum at this point. ---

Slr, I lost my tab on this one. It's the minimum governance contract from [https://docs.openzeppelin.com/contracts/4.x/governance](https://docs.openzeppelin.com/contracts/4.x/governance). For reference, here is my code [https://github.com/DeFipedia/defipedia-protocol/blob/develop/contracts/DefipediaGovernor.sol](https://github.com/DeFipedia/defipedia-protocol/blob/develop/contracts/DefipediaGovernor.sol). I have future plans to modify this, and I can see how I will refactor them, but here I am just importing, setting up required, and overriding required functions. I have seen a common suggestion of using a truffle tool, but I am on hardhat. I am still struggling to figure out what I did wrong from the article. ---

Your contract compiles without warnings with optimizations on. It's below the contract size limit. ---

Can you please share that optimization snippet, please? Because, I still have it for some reason. ![Screenshot from 2021-11-16 22-53-37](https://us1.discourse-cdn.com/flex022/uploads/zeppelin/original/2X/9/96dd196c66d508d78442ede82e56f59b427d93ce.png) ---

Your config is wrong. `settings` goes under `solidity`. See Hardhat docs: [Configuration](https://hardhat.org/config/). ---

Oh, that was an idiotic mistake on my part. Thanks for helping me with it.
