The PoolTogether Prize Savings Protocol Ethereum smart contracts.

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

This project is available as an NPM package:

$ yarn add @pooltogether/pooltogether-contracts

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 CompoundPrizePoolBuilder artifact:

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

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')

First clone this repository and enter the directory.

Switch to the version-3 branch:

$ git checkout version-3

Install dependencies:

$ yarn

We make use of Buidler and buidler-deploy

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

$ yarn start

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

Start up a Buidler Console:

$ buidler console --network localhost

Now you can load up the deployed contracts using buidler-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))

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.
