Challenge 1: The Greeting

In this challenge, you need to register a team and get your first flag NFT! The contract allows teams to register with a name and team size.

• Stores team information in a mapping
• Mints an NFT flag to the registered team

Solution

This is a straightforward challenge! To solve it:

1. Call the registerTeam function with:
   • Any non-empty string as the team name
   • A team size between 1 and 4

Example solution:

challenge.registerTeam("My Team", 2);

That's it! The contract will store your team information and mint the flag NFT to your address.

Why this works:

• The name is non-empty, satisfying the first require check
• The team size (2) is between 1 and 4, satisfying the second require check
• The function will automatically mint the flag NFT to your address

Congratulations on getting your first flag! 🎉
