Getting Started

First we setup some dependencies: Golang and ganache-cli. But no worries, we will walk you through it 😌

Tutorial Source Code

To make it easier to follow the tutorial, you may already clone the source code repository:

cd $GOPATH/src
git clone
cd perun-tutorial/go-perun-test
# Initialize Golang
go mod tidy

Running the code is the last part, but feel free to try it out first.


The tutorial source code will be written in Golang. The official Golang installation guide can be found here. Restart your shell and check the installation by running:

go version

Ganache CLI

For the purpose of this tutorial we will use ganache-cli for providing us with a local Ethereum blockchain for testing our application locally. Install ganache-cli by following the instructions on the web page. You can check if ganache-cli is installed by running:

ganache-cli --version

When we run our local blockchain, we usually configure accounts that we want to prefund. We will do this by specifying a mnemonic. A mnemonic is a sequence of randomly chosen words from which account secret keys can be derived. For the purpose of this tutorial we will use the following mnemonic:

"pistol kiwi shrug future ozone ostrich match remove crucial oblige cream critic"


Always keep your mnemonic private. Do not use the example mnemonic with real funds.
