How to deploy a smart contract in Rust

Soroban contracts are small programs written in the Rust programming language. In this tutorial we'll walk you through setting up your local environment so that you're ready to build Smart Contracts in Rust. If you're wondering why Rust and not Solidity, read this to compare the platforms.

To build and develop contracts you need only a couple prerequisites:

• A Rust toolchain

• An editor that supports Rust

• Soroban CLI

• Install Rust

If you use macOS, Linux, or another Unix-like OS, the simplest method to install a Rust toolchain is to install rustup. Install rustup with the following command.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

If you use Windows, or need an alternative method of installing Rust, check out:
https://www.rust-lang.org/tools/install

Install the target

Install the wasm32-unknown-unknown target.

rustup target add wasm32-unknown-unknown

Configure an Editor

Many editors have support for Rust. Visit the following link to find out how to configure your editor:
https://www.rust-lang.org/tools

A popular editor is Visual Studio Code:

Visual Studio Code editor.
Rust Analyzer for Rust language support.
CodeLLDBfor step-through-debugging.

Install the Soroban CLI

The Soroban CLI can execute Soroban contracts in the same environment the contract will execute on network, however in a local sandbox.

Install the Soroban CLI using cargo install.

cargo install --locked --version 0.8.0 soroban-cli
