On Mac and Linux, run this single command to install Arcium: 
curl --proto '=https' --tlsv1.2 -sSfL https://install.arcium.com/ | bash
See the arcup version manager for details on managing tooling versions. This script will:
  • Check for all required dependencies
  • Install Linux build dependencies automatically (if needed)
  • Download and install arcup for your platform
  • Install the latest Arcium CLI (command-line interface for interacting with the Arcium Network and managing computations)
  • Install the Arx node (the core node software that performs confidential computations in the Arcium Network)

​
Prerequisites

Before running the installation script, make sure you have these dependencies installed: The installation script will check for all these dependencies and provide clear instructions if any are missing.

​
Manual installation

If you prefer to install manually, you can still use the traditional method. See the arcup version manager for details on managing tooling versions. Install arcup. We currently publish pre-built targets for x86 Linux and Apple Silicon. We do not support Windows at the moment.
  • x86_64_linux
  • aarch64_macos
You can install it by replacing <YOUR_TARGET> with the target you want to install, and running the following command: 
TARGET=x86_64_linux && curl "https://bin.arcium.com/download/arcup_${TARGET}_0.10.3" -o ~/.cargo/bin/arcup && chmod +x ~/.cargo/bin/arcup
Install the latest version of the CLI using arcup: 
arcup install
Verify the installation: 
arcium --version

​
Shell completions

Generate tab-completion scripts for your shell: 
arcium completions bash >> ~/.bashrc
Restart your shell or source the config file to activate completions.

​
Issues

Installation might fail due to a variety of reasons. This section contains a list of the most common issues and their solutions, taken from Anchor’s installation guide.

​
Platform-specific issues

Windows Users: Arcium is not currently supported on Windows. We recommend using Windows Subsystem for Linux (WSL2) with Ubuntu for the best experience. Linux Systems: You may need additional dependencies. On Ubuntu/Debian: 
sudo apt-get update && sudo apt-get upgrade && sudo apt-get install -y pkg-config build-essential libudev-dev libssl-dev

​
Incorrect $PATH

Rust binaries, including arcup and arcium, are installed to the ~/.cargo/bin directory. Since this directory is required to be in the PATH environment variable, Rust installation tries to set it up automatically, but it might fail to do so on some platforms. To verify that the PATH environment variable was set up correctly, run: 
which arcium
The output should look like (with your username): 
/home/user/.cargo/bin/arcium
Shell-Specific PATH Issues: If which arcium returns nothing, add the cargo bin directory to your PATH:
  • Bash/Zsh: Add to ~/.bashrc or ~/.zshrc: 
    export PATH="$HOME/.cargo/bin:$PATH"
  • Fish: Add to ~/.config/fish/config.fish: 
    set -gx PATH $HOME/.cargo/bin $PATH
After editing, restart your terminal or run source ~/.bashrc (or equivalent for your shell).
