Setup, build, and deploy a Solana program locally in Rust

Rust is the most common programming language to write Solana programs with. This quickstart guide will demonstrate how to quickly setup, build, and deploy your first Rust based Solana program to the blockchain.

Do you have the Solana CLI installed?

This guide uses the Solana CLI and assumes you have setup your local development environment. Checkout our local development quickstart guide here to quickly get setup.

What you will learn #

  • how to install the Rust language locally
  • how to initialize a new Solana Rust program
  • how to code a basic Solana program in Rust
  • how to build and deploy your Rust program

Install Rust and Cargo #

To be able to compile Rust based Solana programs, install the Rust language and Cargo (the Rust package manager) using Rustup:

curl --proto '=https' --tlsv1.2 -sSf | sh

Run your localhost validator #

The Solana CLI comes with the test validator built in. This command line tool will allow you to run a full blockchain cluster on your machine.


Run the Solana test validator in a new/separate terminal window that will remain open. This command line program must remain running for your localhost validator to remain online and ready for action.

Configure your Solana CLI to use your localhost validator for all your future terminal commands and Solana program deployment:

solana config set --url localhost

Create a new Rust library with Cargo #

Solana programs written in Rust are libraries which are compiled to BPF bytecode and saved in the .so format.

Initialize a new Rust library named hello_world via the Cargo command line:

cargo init hello_world --lib
cd hello_world

Add the solana-program crate to your new Rust library:

cargo add solana-program
Pro Tip

It is highly recommended to keep your solana-program and other Solana Rust dependencies in-line with your installed version of the Solana CLI. For example, if you are running Solana CLI 1.17.17, you can instead run:

cargo add solana-program@"=1.17.17"

This will ensure your crate uses only 1.17.17 and nothing else. If you experience compatibility issues with Solana dependencies, check out the Solana Stack Exchange

Open your Cargo.toml file and add these required Rust library configuration settings, updating your project name as appropriate:

name = "hello_world"
crate-type = ["cdylib", "lib"]

Create your first Solana program #

The code for your Rust based Solana program will live in your src/ file. Inside src/ you will be able to import your Rust crates and define your logic. Open your src/ file in your favorite editor.

At the top of, import the solana-program crate and bring our needed items into the local namespace:

use solana_program::{

Every Solana program must define an entrypoint that tells the Solana runtime where to start executing your onchain code. Your program's entrypoint should provide a public function named process_instruction:

// declare and export the program's entrypoint
// program entrypoint's implementation
pub fn process_instruction(
    program_id: &Pubkey,
    accounts: &[AccountInfo],
    instruction_data: &[u8]
) -> ProgramResult {
    // log a message to the blockchain
    msg!("Hello, world!");
    // gracefully exit the program

Every onchain program should return the Ok result enum with a value of (). This tells the Solana runtime that your program executed successfully without errors.

This program above will simply log a message of "Hello, world!" to the blockchain cluster, then gracefully exit with Ok(()).

Build your Rust program #

Inside a terminal window, you can build your Solana Rust program by running in the root of your project (i.e. the directory with your Cargo.toml file):

cargo build-bpf

After each time you build your Solana program, the above command will output the build path of your compiled program's .so file and the default keyfile that will be used for the program's address. cargo build-bpf installs the toolchain from the currently installed solana CLI tools. You may need to upgrade those tools if you encounter any version incompatibilities.

Deploy your Solana program #

Using the Solana CLI, you can deploy your program to your currently selected cluster:

solana program deploy ./target/deploy/

Once your Solana program has been deployed (and the transaction finalized), the above command will output your program's public address (aka its "program id").

# example output
Program Id: EFH95fWg49vkFNbAdw9vy75tM7sWZ2hQbTTUmuACGip3

Congratulations! #

You have successfully setup, built, and deployed a Solana program using the Rust language.

Check your wallet balance!

Check your Solana wallet's balance again after you deployed. See how much SOL it cost to deploy your simple program?
