Welcome to the world of smart contracts and Clarinet! This tool is designed to simplify the understanding, development, testing, and deployment of smart contracts built with Clarity. Packed with features like a REPL environment and a testing harness, Clarinet makes it easy for developers to get started. This guide will walk you through the installation and basic usage of Clarinet.

Understanding What Clarinet Is

Think of Clarinet as a launchpad for your rocket, where the rocket represents your smart contract. Just like a launchpad helps you prepare and ready your rocket for a successful trip to space, Clarinet prepares you to create, test, and deploy your smart contracts on different environments, such as devnet, testnet, and mainnet.

Installation

Before you can use Clarinet, you’ll need to install it on your system. Below are instructions for different platforms.

Install on macOS (Homebrew)

Run the following command in your terminal:

brew install clarinet

Install on Windows

You have two options to install Clarinet on Windows:

• Use the MSI installer from the releases page.
• Or use Winget:

winget install clarinet

Install from a Pre-Built Binary

You can also download the latest release from the releases page. After unzipping the binary, move it to a directory in your system path:

wget -nv https://github.com/hirosystems/clarinet/releases/download/v0.27.0/clarinet-linux-x64-glibc.tar.gz -O clarinet-linux-x64.tar.gz
tar -xf clarinet-linux-x64.tar.gz
chmod +x ./clarinet
mv ./clarinet /usr/local/bin

Note: On macOS, you might need to run the following command to remove security warnings:

sudo xattr -d com.apple.quarantine /path/to/downloaded/clarinet/binary

Install from Source Using Cargo

If you prefer to install Clarinet from source, ensure that you have Rust installed. You can install required packages by running:

sudo apt install build-essential pkg-config libssl-dev curl

Then build Clarinet using:

git clone https://github.com/hirosystems/clarinet.git
cd clarinet
cargo install

For the latest stable version, switch to the main branch:

git checkout main

Getting Started with Clarinet

After installing Clarinet, you can start creating your smart contracts. Let’s walk through the basic steps.

Setup Shell Completions

Enabling tab-completion will make your work easier. Use the following command to generate the shell completion scripts:

clarinet completions (bash | elvish | fish | powershell | zsh)

Create a New Project

To create a new Clarinet project, run:

clarinet new my-project
cd my-project

This command sets up the directory structure for a new project, including essential configuration files.

Add a New Contract

Adding a new smart contract to your project is a breeze. Execute:

clarinet contract new bbtc

This command will create the contract and its associated test files effortlessly.

Testing Your Contracts

Clarinet provides syntax checkers to ensure the validity of your contracts. To check all contracts in your project, use:

clarinet check

If everything is in order, you will receive a success message. For contract-specific checks, use:

clarinet check path/to/file.clar

Dynamic Testing with Debugging

With the ability to step through your code, debugging in Clarinet allows you to trace functionality during execution. Start the interactive console with:

clarinet console

Troubleshooting

If you encounter issues while using Clarinet, here are some troubleshooting tips:

• Ensure you have the latest version installed by checking the releases page.
• If you face any errors during deployment, confirm your environment settings and the version compatibility.
• Check your command syntax if you’re getting unexpected behavior.
• If issues persist, consider asking for help in the community or on relevant forums.
