My Ethernaut foundry solutions

In this repository, you'll find my answers to the puzzles presented in OpenZeppelin's Ethernaut wargames. With the help of Foundry, every puzzle comes with its own test suite (found in test/.t.sol), related scripts (in script/.s.sol), and a descriptive guide. Additionally, certain puzzles highlight an exploit available in src/*.sol.

Setup Instructions:

1. Download and set up Foundry.
2. Set up a testing wallet, for instance using MetaMask.
3. Create a .env file by duplicating .env.example and then input the necessary keys and instance addresses.
4. Integrate a Sepolia RPC URL in foundry.toml. You can obtain this from sources like Alchemy or Infura.

How to Execute Each Challenge:

Here's a general workflow:

To run tests:

forge test -vvvv
# or for a specific challenge 
forge test -vvvv --match-path ./test/01/Fallback.t.sol

To execute scripts:

forge script ./script/01/Fallback.s.sol --broadcast -vvvv --rpc-url sepolia
