FriendrCoin

Also known as the Metaverse's first dating app, FriendrCoin is a decentralized friend-matching application built on top of Ethereum. The dApp supports creating a profile, swiping on other profiles, matching, messaging and selecting messages to be shown on the public dashboard. Public dashboard messages have voting functionality where upvotes pay one FriendrCoin to the author's wallet and downvotes remove one FriendrCoin from the author's wallet (negative balance not allowed).

Each right swipe costs 1 FriendrCoin and a match returns that FriendrCoin to your wallet. Left swipes are free. Note that creating/editing your profile, swiping, messaging and voting are transactions that incur a gas fee payable in Matic.

This dApp is deployed on Polygon mainnet polygon gas fees are quite low (less than 0.01 USD on average, compared to ~$100 USD on Ethereum mainnet). Note that gas fees are paid in Matic. You can get small amounts of Matic from the matic faucet. To do so, be sure you have added Polygon Mainnet as a network in your Metamask wallet by following these instructions.

You can trade or provide liquidity for FriendrCoin on Quickswap. Note that you may need to import the token by pasting in the below coin address.

How to run

Docker

1. See readme in docker dir

Locally

1. Run yarn install in the root dir
2. Run yarn chain in one terminal
3. Once the first terminal is dumping ETH network logs, run yarn deploy in the second terminal
4. When the second terminal finishes, run yarn start in that terminal to start the web app

BE Test Suite

1. Run yarn test

Test deployments

Notice that in packages/hardhat/deploy there are two files - one for local and one for a remote network.

Right now, running yarn deploy will run both, which is not what you want. If you want to run locally, delete the test file 01_deploy_your_contract_to_test.js but DO NOT COMMIT THAT DELETION. Similarly, if you want to deploy to a network, delete the local file but DO NOT COMMIT THAT DELETION. To deploy to a test net, eg rinkeby, run yarn deploy --network rinkeby after setting up your test_prv_key.txt file with your deploy wallet's private key. Do not commit private keys.

File structure

Solidity code lives in packages/hardhat/contracts and packages/react-app houses the FE code
