## Max Code Size Tester
**Test `MAX_CODE_SIZE` of your EVM.**
[`MAX_CODE_SIZE`](https://eips.ethereum.org/EIPS/eip-170) refers to the maximum length of a smart contract's runtime bytecode.
Runtime bytecode is different from creation bytecode. For example, the Solidity compiler generates creation bytecode (binary) from source code (Solidity). When this creation bytecode is deployed onchain, it gets executed, and returns runtime bytecode, which is set as the code of the smart contract.
## Usage
> [!CAUTION]
> This program deploys a smart contract onchain to verify `MAX_CODE_SIZE`. If run in a production environment, it will incur real transaction costs. Use only in test networks unless you fully understand the implications.
I have read and understood the above warning. Show me the usage instructions.
**Prerequisites**
```shell
curl -L https://foundry.paradigm.xyz | bash
```
**Get**
```shell
git clone [email protected]:ZeroEkkusu/max-code-size-tester.git
cd max-code-size-tester
forge install
```
**Run**
```shell
forge script MaxCodeSizeTester \
--rpc-url \
--broadcast \
--private-key \
--sig "run(uint256)" \
```
It is recommended to test `code_size` of
- $max - 1$
- $max$
- $max + 1$
where $max$ is the `MAX_CODE_SIZE` of the EVM in bytes.
Only $max + 1$ should fail.
