A Concordium piggy bank

The piggy bank smart contract

In this tutorial, we are going to build a simple smart contract modelling a piggy bank. It should allow any account to insert GTU, and only the owner to smash it, taking all of the GTU 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 our piggy bank smart contract with unit tests.

Warning

The reader is assumed to have basic knowledge of what a blockchain and smart contracts are, and to have some experience with Rust.
