CTF: Ethernaut

What is Ethernaut?

Ethernaut is an open-source capture-the-flag (CTF) game by the Openzeppelin Team to help improve smart contract development or security. The game is played on the Ethereum-Virtual-Machine (EVM); each level consists of a smart contract to be hacked. At the time of writing, there are 27 levels, level 0 to level 26, of varying difficulty.
