Language for building DeFi apps on Radix.



  1. Install Rust - this requires Rust 1.70+ (if rust is already installed, upgrade with rustup update)
    • Windows:
      git config --system core.longpaths true
    • macOS:
      • Make sure you have the xcode command line tools: xcode-select --install.

      • Install cmake: brew install cmake llvm
        Add LLVM to the system path by adding below line to the:

        • ~/.profile if bash is the default shell
        • ~/.zshrc if zsh is the default shell
        • respective config file in case of other shell
        PATH="$(brew --prefix llvm)/bin:$PATH"

        You can check, which shell is the default one by inspecting $SHELL variable:

        echo $SHELL
      • Install the Rust compiler:

      curl --proto '=https' --tlsv1.2 -sSf | sh
    • Linux:
      • Make sure a C++ compiler, LLVM, cmake and clang is installed:
      sudo apt install build-essential llvm cmake clang
      • Install the Rust compiler:
      curl --proto '=https' --tlsv1.2 -sSf | 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 Radix CLIs
    cargo install radix-clis

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/;
  • Test code is within tests/
  1. Build your package:
scrypto build
  1. Run tests:
scrypto test

Playing with Radix Engine

Action Command
Create an account resim new-account
Change the default account resim set-default-account <account_address> <account_public_key>
Create a token with fixed supply resim new-token-fixed <amount>
Create a token with mutable supply resim new-token-mutable <minter_resource_address>
Create a badge with fixed supply resim new-badge-fixed <amount>
Create a badge with mutable supply resim new-badge-mutable <minter_resource_address>
Mint resource resim mint <amount> <resource_address> <minter_resource_address>
Transfer resource resim transfer <amount> <resource_address> <recipient_component_address>
Publish a package resim publish <path_to_package_dir>
Call a function resim call-function <package_address> <blueprint_name> <function> <args>
Call a method resim call-method <component_address> <method> <args>
Export the definition of a package resim export-package-definition <package_address> <output>
Show info about an entity resim show <id>
Show info about default account resim show
List all entities resim show-ledger
Reset ledger state resim reset

Note: The commands use the default account as transaction sender.

Compile blueprints with dockerized radix-clis

Follow this guide to build reproducible WASM and RDP files for your Scrypto blueprints.

Using local docker image

The Dockerfile in the root of the repo should be work to build a docker image which will contain all the dependencies needed to be able build a blueprint using scrypto.

Build the docker image like. From the repo root

docker build -t radixdlt/radix-clis .

Then build your package by just running

docker run -v <path-to-your-scrypto-crate>:/src radixdlt/radix-clis

Using published docker image

If you would like to avoid building the docker image, you can skip the build step and do the second step directly, docker will automatically download the docker image we publish

Build your blueprints directly with

docker run -v <path-to-your-scrypto-crate>:/src radixdlt/radix-clis

Project Layout

  • radix-substate-store-queries: Interprets data in substate data by injecting high-level knowledge.
  • radix-transaction-scenarios: Defines various transaction scenarios, for testing.
  • radix-transactions: Radix transaction manifest compiler, transaction models, signing and validating logic.
  • sbor-derive: Macros for encoding and decoding SBOR data.
  • sbor: A generic binary data format, upon which Scrypto SBOR and Manifest SBOR are built.

Assets under assets-lfs are stored in Git LFS.

To fetch files from LFS, install git-lfs first:

  • MacOS
    brew install git-lfs
  • Ubuntu
    curl -s | sudo bash
    sudo apt-get install git-lfs

and then:

git lfs install
git lfs pull
