Environment Setup

Install and Configure the Rust Toolchain

Install Rust by running the following shell commands:

# Install
curl --proto '=https' --tlsv1.2 -sSf <https://sh.rustup.rs> | sh
# Configure
source ~/.cargo/env

Configure to the latest stable and add nightly + Wasm target

rustup default stable
rustup update
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly

ink! contracts use nightly version of Rust, so you can also set up default to nightly (optional)

rustup default nightly

To build contracts, you will need to install cargo-contract. You can find the installation instructions here.
