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
