The piggy bank smart contract

In this tutorial, you are going to build a simple smart contract modelling a piggy bank. It should allow any account to insert CCD and only the owner to smash it, taking all of the CCD inside.

In the first part, you will learn how to write the very basic piggy bank smart contract using the Rust programming language.

The second part is about how to test your piggy bank smart contract with unit tests.
