- Assumptions and constraints - About the proposed solution - PoolDeposit - PoolRewards - How EthPool calculate the total of an account? Rinkeby Link
-
From the "challenge readme" I assume that any rewards deposits without any pool deposit lead to inaccessible funds so the proposed solution block it.
-
The proposed solution supports rewards deposits for any period.

Prerequisites
Please install or have installed the following:
- Install Brownie, if you haven't already. Here is a simple way to install brownie.
python3 -m pip install --user pipx
python3 -m pipx ensurepath
# restart your terminal
pipx install eth-brownie
Or, if that doesn't work, via pip
pip install eth-brownie
If you want to be able to deploy to testnets, do the following.
Set your WEB3_INFURA_PROJECT_ID
, and PRIVATE_KEY
environment variables.
You can get a WEB3_INFURA_PROJECT_ID
by getting a free trial of Infura. At the moment, it does need to be infura with brownie. If you get lost, you can follow this guide to getting a project key. You can find your PRIVATE_KEY
from your ethereum wallet like metamask.
You'll also need testnet rinkeby ETH and LINK. You can get LINK and ETH into your wallet by using the rinkeby faucets located here. If you're new to this, watch this video.
You can add your environment variables to the .env
file:
export WEB3_INFURA_PROJECT_ID=<PROJECT_ID>
export PRIVATE_KEY=<PRIVATE_KEY>
export PRIVATE_KEY_B=<PRIVATE_KEY_B> //to work with 2 accounts
AND THEN RUN source .env
TO ACTIVATE THE ENV VARIABLES
(You'll need to do this everytime you open a new terminal, or learn how to set them easier)
DO NOT SEND YOUR PRIVATE KEY WITH FUNDS IN IT ONTO GITHUB
For local testing install ganache-cli
npm install -g ganache-cli
or
yarn add global ganache-cli
All the scripts are designed to work locally or on a testnet. You can add a ganache-cli or ganache UI chain like so:
brownie networks add Ethereum ganache host=http://localhost:8545 chainid=1337
And update the brownie config accordingly. There is a deploy_mocks
script that will launch and deploy mock Oracles, VRFCoordinators, Link Tokens, and Price Feeds on a Local Blockchain.
brownie run scripts/deploy.py
To run the unit tests:
brownie test
