📖 About

starknet_in_rust is an implementation of Starknet in Rust. It makes use of cairo-vm, the Rust implementation of the Cairo virtual machine.

🌅 Getting Started

Dependencies

• Rust 1.70
• A working installation of cairo-lang 0.12 (for compiling the cairo files)
• [Optional, for testing purposes] Heaptrack

Installation

Run the following make targets to have a working environment (if in Mac or if you encounter an error, see the subsection below):

Linux (x86-64)

$ make deps
$ make build

OSX (Apple Silicon)

$ make deps-macos
$ make build

Check the Makefile for additional targets.

RPC State Reader

In order to use the RPC state reader add an Infura API key in a .env file at root:

INFURA_API_KEY={some_key}

How to manually install the script dependencies

cairo-lang requires the gmp library to build. You can install it on Debian-based GNU/Linux distributions with:

sudo apt install -y libgmp3-dev

In Mac you can use Homebrew:

brew install gmp

In Mac you'll also need to tell the script where to find the gmp lib:

export CFLAGS=-I/opt/homebrew/opt/gmp/include LDFLAGS=-L/opt/homebrew/opt/gmp/lib

🚀 Usage

Running simple contracts

You can find a tutorial on running contracts here.

Using the CLI

You can find an example on how to use the CLI here

Testing

Add an Infura API key.

Run the following command:

$ make test

Profiling

Run the following command:

$ make flamegraph

to generate a flamegraph with info of the execution of the main operations.

Benchmarking

Read the 'bench_integration.py' file to identify which lines need to be commented out for accurate results. Comment out those lines and then run the following command:

$ make benchmark
