Wallet (Backend)

have developed a backend project that allows the creation of users based on the following information:

email, password, first name, last name, phone number, and national ID. It is a policy in our system that

email, phone number, and national ID must be unique. When a user is created, an immediate wallet

is assigned to them with zero cash. Users have the option to acquire multiple wallets and can transfer

money between users using their respective wallet IDs. Additionally, every user has access to a detailed

transaction history.
