ZoKrates is a toolbox for zkSNARKs on Ethereum.

This is a proof-of-concept implementation. It has not been tested for production.

Getting Started

Load the ZoKrates Plugin on Remix to write your first SNARK program!

Alternatively, you can install the ZoKrates CLI:

curl -LSfs | sh

Have a look at the documentation for more information about using ZoKrates. Get started, then try a tutorial!

npm i -g prettier
prettier --write "./**/*.{js,ts,json}" --ignore-path .gitignore
