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.x OR v16.x)
• Yarn (Javascript Package Manager)

Installing The Correct Node Version Using NVM

Dark Forest is built and tested using Node.js v14/v16 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 or v16

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 --whitelist false

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
