Level 0: Hello Ethernaut

The first challenge is an introduction to the Ethernaut platform. Players are tasked with simply interacting with the Ethernaut smart contract to register their presence.

Goal: Call the info() function of the contract to retrieve a welcome message.

Solution: To solve this challenge, the user must:

1. Deploy the contract and connect to it using a Web3 provider (like MetaMask).

2. Call the info() function through the console or an interface to read the welcome message.

Here’s a simple interaction in JavaScript using Web3:

const instance = await Ethernaut.at(contractAddress);
const message = await instance.info();
console.log(message); // Displays "Hello Ethernaut!"

Lessons Learned:

• Get familiar with interacting with smart contracts using Web3 or similar libraries.

• Understand the importance of reading the contract’s interface to identify callable functions.
