In this article, we will walk you through how to deploy a Smart Contract in Solana. In Solana, all Smart Contracts are called On-Chain Program. So, from now-on, we will call it program instead of Smart Contract. We will use Solana’s Hello World as an example on how to deploy. You may find its github here. Below, we will introduce how to deploy this contract on a local cluster. If you are not familiar with how to setup a local cluster, you can take a look of my previous post first.

Installation

Suppose you have already setup your local cluster successfully, next thing you should do is download the hello-world project and its dependencies. To deploy hello-world, you would also need to download npm and node.

$ sudo apt-get update
$ sudo apt-get nodejs npm

After installation, clone the helloworld project and build it

$ git clone https://github.com/solana-labs/example-helloworld.git
$ cd example-helloworld
$ npm install
$ npm run build:program-rust

Deploy the contract

Now, your installation should be done. Let’s spin up a local cluster:

$ solana-test-validator

Now, open a new console, deploy the contract:

$ cd example-helloworld
$ solana program deploy dist/program/helloworld.so
$ npm run start

If you see something like below, congratulations! You have successfully deployed your first smart contract on Solana!

In next post, we will walk through the code of hello-world and see how this magic works. So, stay tuned and see you soon!
