Foundry Book

Installation

If you face any issues while installing, check out the FAQ.

Precompiled binaries

Precompiled binaries are available from the GitHub releases page. These are better managed by using Foundryup.

Using Foundryup

Foundryup is the Foundry toolchain installer. You can find more about it here.

Open your terminal and run the following command:

curl -L https://foundry.paradigm.xyz | bash

This will install Foundryup, then simply follow the instructions on-screen, which will make the foundryup command available in your CLI.

Running foundryup by itself will install the latest (nightly) precompiled binaries: forge, cast, anvil, and chisel. See foundryup --help for more options, like installing from a specific version or commit.

ℹ️ Note

If you’re on Windows, you will need to install and use Git BASH or WSL, as your terminal, since Foundryup currently does not support Powershell or Cmd.

Building from source

Prerequisites

You will need the Rust compiler and Cargo, the Rust package manager. The easiest way to install both is with rustup.rs.

Foundry generally only supports building on the latest stable Rust version. If you have an older Rust version, you can update with rustup:

rustup update stable

On Windows, you will also need a recent version of Visual Studio, installed with the “Desktop Development With C++” Workloads option.

Building

You can either use the different Foundryup flags:

foundryup --branch master
foundryup --path path/to/foundry

Or, by using a single Cargo command:

cargo install --git https://github.com/foundry-rs/foundry --profile local --locked forge cast chisel anvil

Or, by manually building from a local copy of the Foundry repository:

# clone the repository
git clone https://github.com/foundry-rs/foundry.git
cd foundry
# install Forge
cargo install --path ./crates/forge --profile local --force --locked
# install Cast
cargo install --path ./crates/cast --profile local --force --locked
# install Anvil
cargo install --path ./crates/anvil --profile local --force --locked
# install Chisel
cargo install --path ./crates/chisel --profile local --force --locked

Installing for CI in Github Action

See the foundry-rs/foundry-toolchain GitHub Action.

Using Foundry with Docker

Foundry can also be used entirely within a Docker container. If you don’t have it, Docker can be installed directly from Docker’s website.

Once installed, you can download the latest release by running:

docker pull ghcr.io/foundry-rs/foundry:latest

It is also possible to build the docker image locally. From the Foundry repository, run:

docker build -t foundry .

For examples and guides on using this image, see the Docker tutorial section.

ℹ️ Note

Some machines (including those with M1 chips) may be unable to build the docker image locally. This is a known issue.
