Icon LinkToolchain installation

This guide will help you to install the Fuel toolchain binaries and prerequisites.
This guide covers the following topics:
  1. Installing Rust
  2. Installing the Fuel toolchain using fuelup
  3. Changing your default toolchain
  4. Setting up a local wallet

Icon LinkInstalling Rust

The Fuel toolchain is built on top of the Rust programming language. To install Rust, you can use the rustup tool.
Run the following command in your shell; this downloads and runs rustup-init.sh, which in turn downloads and runs the correct version of the rustup-init executable for your platform. 
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Check the official Rust documentation to get more information on installing the Rust toolchain Icon Link.

Icon LinkInstalling the Fuel toolchain using fuelup

fuelup is the official package manager for Fuel that installs the Fuel toolchain from the official release channels, enabling you to easily switch between different toolchains and keep them updated. It makes building and maintaining Sway applications simpler with forc and fuel-core Icon Link for common platforms.

💡 Check out the fuelup docs Icon Link for more information.

Icon LinkRunning fuelup-init

To install the Fuel toolchain, you can use the fuelup-init script. This will install forc, forc-client, forc-fmt, forc-lsp, forc-wallet as well as fuel-core in ~/.fuelup/bin.
👉 Just paste the following line in your terminal and press Enter. 
curl https://install.fuel.network | sh
Icon InfoCircle
🚧 Be aware that currently we do not natively support Windows. If you wish to use fuelup on Windows, please use Windows Subsystem for Linux.

Icon LinkSetup PATH

Once the script is downloaded, it will be executed automatically. The fuelup-init script will prompt you with the question below: 
fuelup uses "/home/username/.fuelup" as its home directory to manage the Fuel toolchain, and will install binaries there.

To use the toolchain, you will have to configure your PATH, which tells your machine where to locate `fuelup` and the Fuel toolchain.

If permitted, fuelup-init will configure your PATH for you by running the following:

    echo "export PATH="$HOME/.fuelup/bin:$PATH"" >> /home/username/.bashrc

Would you like fuelup-init to modify your PATH variable for you? (N/y)
👉 Press the Y key in your terminal and press Enter to modify your PATH.

Icon LinkChecking the installation

After allowing the fuelup-init script to modify your PATH variable, you will see a lot of information about packages being downloaded and installed. If everything goes as expected you will see the following message: 
The Fuel toolchain is installed and up to date

fuelup 0.20.0 has been installed in /home/username/.fuelup/bin. 
To fetch the latest toolchain containing the forc and fuel-core binaries, run 'fuelup toolchain install latest'. 
To generate completions for your shell, run 'fuelup completions --shell=SHELL'.
👉 Use fuelup --version any time to check which version of the package you are using. 
 fuelup --version
That will output your current fuelup version: 
fuelup 0.21.0

Icon LinkVSCode extensions

If you're using VSCode, we recommend installing the Sway extension Icon Link.

Icon LinkChanging your default toolchain

Just as in Rust Icon Link, Fuel supports multiple toolchains. A toolchain is a collection of tools (such as the compiler, LSP, etc). By default, fuelup includes a series of packages tested to work with each other, providing a reliable set of tools.
The default toolchain configured when you install fuelup is the latest toolchain, which is the stable toolchain compatible with the current beta-5 network.

Icon LinkUpdating fuelup

Make sure you have the latest version of fuelup so you can access the latest features and have the best performance.
👉 Update fuelup by running the following command: 
fuelup self update
Then you will get an output like this: 
Fetching binary from https://github.com/FuelLabs/fuelup/releases/download/v0.19.5/fuelup-0.19.5-aarch64-apple-darwin.tar.gz
Downloading component fuelup without verifying checksum
Unpacking and moving fuelup to /var/folders/tp/0l8zdx9j4s9_n609ykwxl0qw0000gn/T/.tmpiNJQHt
Moving /var/folders/tp/0l8zdx9j4s9_n609ykwxl0qw0000gn/T/.tmpiNJQHt/fuelup to /Users/.fuelup/bin/fuelup

Icon LinkUsing the latest toolchain

The beta-5 network is the latest Fuel testnet. This includes public infrastructure such as the beta-5 faucet Icon Link and the beta-5 graphQL playground Icon Link.
To properly interact with the beta-5 network it is necessary to use the latest toolchain which is installed by default.
👉 Run the following command to verify the installation of latest toolchain: 
fuelup show
If the toolchain was successfully installed, you will see this output: 
installed toolchains
--------------------
latest-x86_64-unknown-linux-gnu (default)

active toolchain
-----------------
latest-x86_64-unknown-linux-gnu (default)
...

Icon LinkInstalling nightly toolchain

In case you want to try out the unreleased features of the Fuel toolchain, you can install the nightly toolchain.
👉 Run the following command to install the nightly toolchain: 
fuelup toolchain install nightly
If the toolchain was successfully installed, you will see this output: 
The Fuel toolchain is installed and up to date
The toolchain was installed correctly, however is not in use yet. Next, you need to configure fuelup to use the nightly toolchain as the default.
👉 Set nightly as your default toolchain with the following command: 
fuelup default nightly
You will get the following output indicating that you have successfully set nightly as your default toolchain. 
default toolchain set to nightly

Icon LinkChecking your current toolchain

Sometimes you might end up using multiple toolchains at once. Don't worry if you get confused about which toolchain you are using, since you can check your current toolchain anytime.
👉 Run the fuelup show command to see the toolchain and the versions of each tool you are using. 
fuelup show
This command will give you the following output 
active toolchain
-----------------
beta-4-x86_64-unknown-linux-gnu (default)
  forc : 0.45.0
    - forc-client
      - forc-deploy : 0.45.0
      - forc-run : 0.45.0
    - forc-doc : 0.45.0
    - forc-explore : 0.28.1
    - forc-fmt : 0.45.0
    - forc-index : 0.20.7
    - forc-lsp : 0.45.0
    - forc-tx : 0.45.0
    - forc-wallet : 0.3.0
  fuel-core : 0.20.4
  fuel-core-keygen : Error getting version string

fuels versions
---------------
forc : 0.45
forc-wallet : 0.45
As you can see, the beta-5 toolchain is active 🚀

Icon LinkSetting up a local wallet

The forc-wallet plugin is packaged alongside the default distributed toolchains when installed using fuelup, so you should already have this installed if you've followed the instructions above.
To initialize a new wallet with forc-wallet, you can run the command below: 
forc wallet new
After typing in a password, be sure to save the mnemonic phrase that is output.
Next, create a new wallet account with: 
forc wallet account new
With this, you'll get a fuel address that looks something like this: fuel1efz7lf36w9da9jekqzyuzqsfrqrlzwtt3j3clvemm6eru8fe9nvqj5kar8.
If you need to list your accounts, you can run the command below: 
forc wallet accounts
