Installation ⚙️

Prerequisites:

Install Kudu, our tool to generate the Yul AST, and add it to your PATH.

Linux:

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install -y python3.7
sudo apt install -y python3.7-dev
sudo apt install -y libgmp3-dev
sudo apt-get install -y python3.7-venv
python3.7 -m venv ~/warp_demo
source ~/warp_demo/bin/activate
cd warp
make warp

MacOs:

brew install python@3.7
brew install gmp
python3.7 -m venv ~/warp_demo
source ~/warp_demo/bin/activate
cd warp
make warp

Usage 💻

You can transpile your Solidity/Vyper contracts with:

warp transpile FILE_PATH CONTRACT_NAME

CONTRACT_NAME is the name of the primary contract (non-interface, non-library, non-abstract contract) that you wish to transpile

To deploy the transpiled program to Starknet use:

warp deploy CONTRACT.json

To invoke a public/external method use:

warp invoke --program CONTRACT.json --address ADDRESS --function FUNCTION_NAME --inputs "INPUTS"

The --inputs flag requires its argument to be a string and have each value separated by a space.

You can check the status of your transaction with:

warp status TX_ID
