Language for building DeFi apps on Radix.

Documentation: https://docs.radixdlt.com/main/scrypto/introduction.html

Installation

  1. Install Rust - this requires Rust 1.60+ (if rust is already installed, upgrade with rustup update)
    • Windows:
    • Linux and macOS:
      • Make sure a C++ compiler and LLVM is installed (sudo apt install build-essential llvm with Ubuntu)
      • Install Rust compiler
      curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
      
  2. Enable cargo in the current shell:
    • Windows:
      • Start a new PowerShell
    • Linux and macOS:
      source $HOME/.cargo/env
      
  3. Add WebAssembly target
    rustup target add wasm32-unknown-unknown
    
  4. Install simulator
    git clone https://github.com/radixdlt/radixdlt-scrypto.git
    cd radixdlt-scrypto
    cargo install --path ./simulator
    
  5. (Optional) Open Scrypto documentation for later use
    ./doc.sh
    

Getting Started

If you want a quick walkthrough of how to deploy and run some code, please see the Run Your First Project tutorial. If you prefer to soldier through on your own, keep reading below.

Writing Scrypto Code

  1. Start by creating a new package:
scrypto new-package <package_name>
cd <package_name>
  1. Check out the files under your current directory:
  • Source code is within src/lib.rs;
  • Test code is within tests/lib.rs.
  1. Build your package:
scrypto build
  1. Run tests:
scrypto test
