3.What did you learn?

• Add to my wallet and using Mumbai test network

• The use of mapping and structs data types

• use hardhat

• Deploy a contract and verify it on Mumbai’s

4.What did you enjoy about the tutorial?

• The use of a new network

• Replace a basic mapping data type for a more complex one using structs

5.How do you think you can use this technology to build useful applications?

• This contract was more complex and use more objects, this exercise is very useful for a more realistic approach about smart contracts

• Feel comfortable with data structures is always a great hard skill in any programming language.

6.Who would you recommend this project to?

Anyone interested in develop and deploy smart contracts using Solidity.
