Voting dApp demo for Oasis Sapphire

Demo Voting App

This is a demo voting app running natively on Oasis Sapphire. The app is a fork of the OPL Secret Ballot.

Backend

This repo is set up for pnpm but other NodeJS package managers should work.

Local Development

We will use Hardhat and Hardhat-deploy to simplify development.

Start local Hardhat network

npx hardhat node

Deploy smart contracts locally

npx hardhat deploy-local --network localhost

We can now reference the deployed contracts in our frontend Vue app.

Modify the .env.development file with the appropriate addresses:

VITE_BALLOT_BOX_V1_ADDR=0x5FbDB2315678afecb367f032d93F642f64180aa3

and

VITE_DAO_V1_ADDR=0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512

Additionally, we will need a Pinata API key to access the pinning service with which we store our ballots as JSON.

VITE_PINATA_JWT=

Start Vue app

pnpm dev

Navigate to http://localhost:5173, and you should be able to create a new poll.

You can use one of the deployed test accounts and associated private key with MetaMask.
