chall_eth

Aggregation of challs based on ethereum from different CTFs.

How to play

1. Clone the repository
2. Install dependencies with yarn install
3. Code your solutions in the provided *.challenge.js files (inside each challenge's folder in the test folder)
4. Run your exploit for a challenge with yarn run challenge-name. If the challenge is executed successfully, you've passed!

Tips and tricks

1. In all challenges you must use the account called attacker. In Ethers, that should translate to using .connect(attacker).
2. To code the solutions, you may need to refer to Ethers and Hardhat docs.
3. In some cases, you may need to code and deploy custom smart contracts (you should put them in contracts/attacker-contracts).
