The Ethernaut is a Web3/Solidity based wargame inspired from overthewire.org, played in the Ethereum Virtual Machine. Each level is a smart contract that needs to be 'hacked'.

I couldn't solve a couple of levels myself , so I cheated a bit 😅 (especially for the Vault and Gatekeeper One levels). Her walkthroughs are great teaching material on Solidity. I also reused some diagram images from her posts.
