This challenge is based on https://ethernaut.openzeppelin.com/

1. Get all the dependencies installed with yarn install
2. Compile all contracts by running npx hardhat compile
3. Run a local node by running npx hardhat node

• If you look inside the contracts/ directory you'll find 8 levels for you to solve!
• Each level directory consists of the same structure, let's check out the first one to illustrate this:
  • CoinFlip.sol: This is the contract you're supposed to hack!
  • AttackingCoinFlip.sol: This is the malicious contract where you'll code the logic to exploit the vulnerable contract!
  • CoinFlip.test.ts: This is the file where you'll be able to test if the contract has been breached
  • CoinFlipHelper.ts: Not all challenges have this Helper file! Only the ones that require you to use ethers to interact with your contract do, which you can do right here! This function is already imported into the tests, so don't worry about anything other than coding!
  • And finally, the README. On this one you'll get all level instructions!
• After you're done writing your hack, run the following command to run the tests and see if you succesfully breached the contract:
  • npx hardhat test contracts/{contract directory}/{contract name}.test.ts
  • Example: npx hardhat test "contracts/1. CoinFlip/CoinFlip.test.ts"

• You can console.log in solidity using hardhat! Read here for more details: https://hardhat.org/tutorial/debugging-with-hardhat-network.html
