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.
The second part is about how to test your piggy bank smart contract with unit tests.
The reader is assumed to have basic knowledge of what a blockchain and smart contracts are, and to have some experience with Rust.
