Dark Forest Smart Contracts

Development Guide

Folder setup

All of our smartcontract related code are located in the /eth directory.

• /eth/contracts contains the smartcontract code written in solidity
• /eth/test contains the test for the smartcontract written in Javascript

Installing Core Dependencies

• Node (v14.15.x)
• Yarn (Javascript Package Manager)

Installing The Correct Node Version Using NVM

Dark Forest is built and tested using Node.js v14.15.x and might not run properly on other Node.js versions. We recommend using NVM to switch between multiple Node.js version on your machine.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
nvm install

After the installation is finished, you can run node --version to verify that you are running v14.15.x

Installing Yarn & Other Dev Dependencies

Refer to Yarn's official documentation for the installation guide.

After you have Yarn installed, run yarn to install dev dependencies:

Run Locally

To run the tests run yarn test

To deploy contracts locally, you'll need to run 2 commands:

1. Start a node by running yarn hardhat:node
2. Then (in another terminal) deploy contracts by running yarn hardhat:dev deploy

You can import the private key of one of the accounts hardhat node created and funded, which are printed when you started the node such as:

Account #2: 0x3097403b64fe672467345bf159f4c9c5464bd89e (100 ETH)
Private Key: 0x67195c963ff445314e667112ab22f4a7404bad7f9746564eb409b9bb8c6aed32
