THIS IS COPIED FROM POOLTOGETHER TO RUN THE APP

PoolTogether Prize Savings Protocol

The PoolTogether Prize Savings Protocol Ethereum smart contracts.

For an overview of the concepts and API please see the documentation

Setup

This project is available as an NPM package:

$ yarn add @pooltogether/pooltogether-contracts

Usage

Artifacts

There are deployment artifacts available in the deployments/ directory. This includes:

• Builders
• Proxy Factories
• Comptroller
• ProxyAdmin

Prize Pools and Prize Strategies are not included, as they are created using the Builders.

For example, to pull in the PoolWithMultipleWinnersBuilder artifact:

const PoolWithMultipleWinnersBuilder = require("@pooltogether/pooltogether-contracts/deployments/rinkeby/PoolWithMultipleWinnersBuilder.json");
const { abi, address, receipt } = PoolWithMultipleWinnersBuilder;

ABIs

Application Binary Interfaces for all PoolTogether contracts and related contracts are available in the abis/ directory.

For example, to pull in the PrizePool ABI:

const PrizePool = require("@pooltogether/pooltogether-contracts/abis/PrizePool.json");

Development

First clone this repository and enter the directory.

Install dependencies:

$ yarn

We use direnv to manage environment variables. You'll likely need to install it.

Testing

We use Hardhat and hardhat-deploy

To run unit & integration tests:

$ yarn test

To run coverage:

$ yarn coverage

To run fuzz tests:

$ yarn echidna

Deployment

Deploy Locally

Start a local node and deploy the top-level contracts:

$ yarn start

NOTE: When you run this command it will reset the local blockchain.

Connect Locally

Start up a Hardhat Console:

$ hardhat console --network localhost

Now you can load up the deployed contracts using hardhat-deploy:

> await deployments.all()

If you want to send transactions, you can get the signers like so:

> let signers = await ethers.getSigners()

Let's mint some Dai for ourselves:

> let dai = await ethers.getContractAt('ERC20Mintable', (await deployments.get('Dai')).address, signers[0])
> await dai.mint(signers[0]._address, ethers.utils.parseEther('10000'))
> ethers.utils.formatEther(await dai.balanceOf(signers[0]._address))

Deploy to Live Networks

Copy over .envrc.example to .envrc

$ cp .envrc.example .envrc

Make sure to update the enviroment variables with suitable values.

Now enable the env vars using direnv

$ direnv allow

Now deploy to a network like so:

$ yarn deploy rinkeby

It will update the deployments/ dir.
