The Phat Contract uses the Rust-based ink! language, and is ultimately compiled to WebAssembly (WASM for short).
- You compile your contract on both macOS and Linux distributions (we use Ubuntu 22.04 as the default Linux distribution);
- For Windows users, we recommend setting up a Linux development environment with a virtual machine (video tutorial).
Note
The Mac M1/M2 chips do not support the deployment of a local testnet at this time. If you are using a machine with these chips, you will have to deploy to the live testnet through DevPHAse, swanky phala, or Phat UI.

Phat Contract shares the same toolchains as ink!.
A prerequisite for compiling Phat Contracts is to have Rust and Cargo (Rust’s project manager) installed.
Rust officially recommends using rustup tool to install and manage different Rust versions. Here’s an installation guide.
We recommend installing cargo-contract. It’s a CLI tool that helps set up and manage contracts written with ink!.
Then you can install the cargo-contract with
# use the `--force` to ensure you are updated to the most recent version
cargo install cargo-contract --force
Then check your cargo-contract and ensure it’s updated to 3.2.x with ink! 4 support
cargo contract --version
# cargo-contract-contract 3.2.0-unknown-x86_64-unknown-linux-gnu
