Oasis Blockvote: Private Sidekick for DAOs

This is a dApp for running ad-hoc unofficial opinion polls for DAO members, or any other group.

The app is a fork of the Oasis Demo Voting App, which is in turn a fork of the OPL Secret Ballot.

This monorepo is set up for pnpm. Install dependencies by running:

pnpm install

Backend

Move to the contracts folder and build smart contracts:

pnpm build

Next, deploy the contract.

Basic Local Hardhat Deployment

Move to the hardhat folder and build smart contracts:

Start the hardhat node:

make build

Deploy smart contracts to that local network:

make deploy-localnet

You can use the --gaslessAccounts and --gaslessFunds parameters to set the number of proxy accounts that can be used to pay for the gas for voters and the amount of tokens each of those accounts will be initially funded.

The deployed DAO contract addresses will be stored inside the frontend folder's .env.development, for example:

VITE_DAO_V1_ADDR=0x5FbDB2315678afecb367f032d93F642f64180aa3

Monitoring Signer Accounts

To monitor accounts, use gv-topup providing DAO address which will show the balances:

pnpm hardhat --network localhost gv-topup --dryrun 0x5FbDB2315678afecb367f032d93F642f64180aa3

To specify minimum balance for gv-topup use --min, remove --dryrun to submit the transactions. For example, to top up the accounts so that each account will have 10 tokens, run:

pnpm hardhat --network localhost gv-topup 0x5FbDB2315678afecb367f032d93F642f64180aa3 --min 10000000000

Adding Signer Accounts

To add more signer accounts:

pnpm hardhat --network localhost gv-newkp 0x5FbDB2315678afecb367f032d93F642f64180aa3

Access Control Lists (ACL)

Use --acl deployment parameter to define the ACL contract policy to use. Supported values:

npx hardhat --network localhost deploy --acl AllowVoterACLv1

Whitelisting the Voters (WhitelistVotersACLv1 only)

To whitelist voters for a specific ballot, gather the following information:

Then, prepare a file containing whitelisted voters addresses, one per line. This list will overwrite any existing whitelisted users. For example:

0x8626f6940E2eb28930eFb4CeF49B2d1F2C9C1199
0xDce075E1C39b1ae0b75D554558b6451A226ffe00

Then, execute the following hardhat task:

npx hardhat --network localhost whitelist-voters 0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512 e386cceaa6ceea2f935d89951e522ac6d7ac777503b234d61b193439de571cfc voters.txt

Deploying to Sapphire Localnet, Testnet and Mainnet

Prepare your hex-encoded private key and store it as an environment variable:

export PRIVATE_KEY=0x...

To deploy the contracts to the Sapphire Localnet, Testnet or Mainnet, use the following commands respectively:

npx hardhat deploy --network sapphire-localnet
npx hardhat deploy --network sapphire-testnet
npx hardhat deploy --network sapphire

Frontend

After compiling the backend, updating .env.development with the corresponding DAO address and chain ID, move to the frontend folder to compile and Hot-Reload frontend for Development:

pnpm dev

This will start the React app, using the contracts deployed to Sapphire Localnet.

Or, you can do:

pnpm dev-staging

This will also start the React app, but it will use the contracts deployed to Sapphire teestnet.

Whichever backend you want to you, after starting the React app, navigate to http://localhost:5173, and you should be able to create a new poll.

If running against localnet, you can use one of the deployed test accounts and associated private key with MetaMask. If you use the same MetaMask accounts on fresh local networks, don't forget to clear your account's activity each time or manually specify the correct account nonce.

Frontend Deployment

You can build assets for deployment by running:

pnpm build

dist folder will contain the generated HTML artifacts.

Different Website Base

If you are running dApp on a non-root base dir, add

BASE_DIR=/my/public/path

to .env.production and bundle the app with

pnpm build-only --base=/my/public/path/

Then copy the dist folder to a place of your /my/public/path location.
