Setup

@0xEval has written an excellent run through of how the repo is configured and how to get setup on it.

Info

This repo is setup to enable you to run the ethernaut levels locally rather than on Rinkeby. As a result you will see some contracts that are not related to individual level but instead to ethernaut's core contracts which determine if you have passed the level.

These are the Ethernaut.sol & BaseLevel.sol contracts in the root of ./src and the factory contracts which have a naming convention of [LEVEL_NAME]Factory.sol in each levels repo. Have a read through if interested in what they do otherwise they can be ignored.

Make sure you're on the latest version of forge, what is your forge —version output? If it doesn’t show a date, try rm -rf ~/.cargo/bin/cast && rm -rf ~/.cargo/bin/forge

At the root of the repo run

foundryup 
forge install 
forge test

File Locations

Individual Levels can be found in their respective folders in the ./src folder.

Eg Fallback is located in ./src/Fallback/Fallback.sol

Tests for each level can be found in the ./src/test folder and have the naming convention [LEVEL_NAME].t.sol

Eg Fallback test are located in ./src/test/Fallback.t.sol
