📂 Project Structure

The code uses Django models to define the Wallet and Transaction models, which represent the user's wallet and transaction records, respectively. The models are related to the User model, which stores user information such as the Telegram user ID and username.

The code also includes error handling mechanisms such as custom exceptions (InsufficientFundsError), input validation, and exception handling for API requests.
