Truffle Deployment Guide

Environment Setup

0. Check whether you Mac has Homebrew installed:

If the command fails, then install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

1. sudo apt install nodejs npm

2. Install OpenZeppelin contracts. At the root of this project.

npm install openzeppelin-solidity

3. Replace the mnemonic variable content with YOUR secret words in truffle.js.(NOTE: your secret words should be held privately in your wallet)

var mnemonic = YOUR_SECRET_WORDS_HERE;

4. Deploy the contract to the Optimism-Goerli network

truffle migrate --reset --network Optimism

5. From the output of the above command, find the address of the RubyETH contract, suppose it is:

0x05149A02DC230588964Dd6D6F196eF38d523c0Fa

Update the Javascript code with the above address in src/rubyClient.js

rubyApp.contracts.rubyETHContract = new rubyApp.web3.eth.Contract(rubyETHabi, YOUR_RUBYETH_CONTRACT_ADDRESS_HERE);
