Let’s play OpenZeppelin Ethernaut CTF — learning Solidity security while playing!

The Ethernaut is a Web3/Solidity based war game created by OpenZeppelin.

Each level is a smart contract that needs to be ‘hacked’. The game acts both as a tool for those interested in learning Ethereum, and as a way to catalog historical hacks in levels. Levels can be infinite, and the game does not require to be played in any particular order.

How to play

If you want to play it by your own, just go to the Ethernaut website and start solving the challenges.

Otherwise, you could clone my own personal repository, remove the solutions in the test folder and build your own! I have explained in the README file how to do it, and it should be pretty easy.

Solutions to each puzzle

Each day I will publish the solution to a new challenge, so stay tuned.
