WASM Basics

Introduction

This chapter will get you started developing smart contracts with ink!.

We will build a simple "Incrementer" contract which holds a number which you can increase with a function call.

Over the course of this chapter you will learn:

• The structure of ink! smart contracts
• To store single values and hash maps
• To safely get and set these values
• To build public and private functions
• To configure Rust to use safe math
