🧑🏻‍🚀 my ethernaut write-ups and solution in foundry

🔋 this project contains solutions for openzeppelin's ethernaut wargames. leveraging foundry, each level has a test set (.t.sol), a script set (.s.sol), and a write-up. some levels also have an exploit at src/.sol.

🔋 note that my "submission foundry scripts" intentionally contain the addresses of my instances hardcoded instead of in the .env file. this serves me as an arxiv, and it's harmless as i use a test wallet for this work.

🔋 by the way, do you remember overthewire? here is my WeChall profile from playing it in 2014.

installing

• install foundry

• create a .env (from .env.example) and add your private and private keys

• add a sepolia rpc url to foundry.toml

---

running each level

• you will find detailed instructions in each write-up, but as a general rule:

• run tests with, for example,
  • forge test -vvvv, or, for example,
  • forge test -vvvv --match-path ./test/01/Fallback.t.sol

• submit scripts with, for example,
  • forge script ./script/01/Fallback.s.sol --broadcast -vvvv --rpc-url sepolia
