Language for building DeFi apps on Radix.

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

1. Install Rust - this requires Rust 1.60+ (if rust is already installed, upgrade with rustup update)
   • Windows:
     • Download and install rustup-init.exe
     • Install "Desktop development with C++" with Build Tools for Visual Studio 2019
     • Install LLVM 13.0.1 (make sure you tick the option that adds LLVM to the system PATH)
   • 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
   

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.

1. Start by creating a new package:

scrypto new-package <package_name>
cd <package_name>

2. Check out the files under your current directory:

• Source code is within src/lib.rs;
• Test code is within tests/lib.rs.

3. Build your package:

scrypto build

4. Run tests:

scrypto test

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

• sbor: The binary data format used by Scrypto.
• sbor-derive: Derives for encoding and decoding Rust struct and enum.
• scrypto: Scrypto standard library.
• scrypto-abi: Scrypto blueprint ABI.
• scrypto-derive: Derives for defining and importing Scrypto blueprints.
• radix-engine: The Scrypto execution engine.
• simulator: A simulator that run Scrypto code on a filesystem based ledger.
• transaction-manifest: Radix transaction manifest compiler.
