1. Installing Scrypto

Overview

Scrypto is Radix's smart-contract language, built on Rust. You need three things: the Rust toolchain, the WebAssembly compilation target, and the Radix CLI tools.

1. Install Rust

Install Rust via rustup. Scrypto 1.3.1 supports Rust 1.81.0 and newer (tested up to 1.92.0).

2. Add the WASM Target

Scrypto compiles blueprints to WebAssembly for deterministic execution on the Radix Engine.

rustup target add wasm32-unknown-unknown

3. Install Radix CLI Tools

The radix-clis crate provides scrypto (compiler), resim (local simulator), and rtmc (manifest compiler).

cargo install --force radix-clis

4. Verify

rustc --version
scrypto --version
resim --version

All three commands should print version numbers without errors.

IDE Setup

For the best experience, install VS Code with the rust-analyzer extension. This gives you inline type hints, autocompletion, and error checking for Scrypto code.

Troubleshooting

Missing WASM target

If you see wasm32-unknown-unknown target not found, re-run:

rustup target add wasm32-unknown-unknown

Outdated toolchain

If builds fail on a fresh install, update Rust:

rustup update
