A full stack monorepo with

- React Native

- Nextjs

- Web3Auth

- Solidity

- Chainlink VRF

- Filecoin NFT.storage

built under The Chainlink 2022 Hackathon 

Test Net Deploy:

## LATEST KUDOS TOKEN CONTRACT ADDRESS (GOERLI): 0x67714a689C38BfEbe0aD191a349aB3084Df415A8

## LATEST FAVORS CONTRACT ADDRESS (GOERLI): 0x693f7fe29CaE09F2110E9dA885769304e6f5cacE

Mobile: 

Web: 

## Setup

1. Create Web3Auth.io Account at 

2. Copy into credentials .env and constant.js

   Note: `WEB_API_ROUTES` would be the URL of the deployed nextjs app ie: vercel

3. yarn install inside the root and web directories

### For smart contract functionality

   1. Receive Test Link from 

   2. Create and Fund a VRF Subscription at 

   3. Deploy the `contracts/KudosToken.sol` via  with a Total Token Supply

   4. Copy Token Contract Address

   5. Deploy the `contracts/FavorsV2.sol` via  with subscription ID and Token Contract Address

   6. Add Favor Contract Address to .env file

## Usage

`yarn ios` - Run iOS App

`yarn android` - Run Android App

`yarn web` - Start Nextjs app

### Features

- Built using Web3auth

- Has nhost for Graph QL DB if needed

- Has Nextjs App for API

- File Reading Functions

- Has Smart Contract for Favor Posting, Retrieving, Completing, and payment

in a new `.env`

   backendUrl: "YOUR_NHOST_BACKEND_URL",

in `App.js`

  clientStorageType: "expo-secure-storage",

To Run Nextjs App:

  `yarn web` in root directory

### To do

- [x] Expo React Native App

- [x] Nextjs App

- [x] Web3Auth - React Native SDK

- [x] Thirdwebjs Auth - Nextjs SDK

- [x] ERC20 Contract

- [x] Chainlink VRF

- [x] FavorsV2 Contract

- [x] Mobile App Smart Contract Function Integration:

        1. Post Button => postFavor(text)

        2. Refresh Favors Button => getAllIncompleteFavors()

        3. Offers Tab => getMyFavors()

        4. Accept Button => acceptFavor

        5. Mark Completed Button => completeFavor(favorId)

- [ ] Fix Nextjs App (Connect to Deployed Contract)

- [ ] User Profile Contract / nHost

- [ ] Use React-Native-Async-Storage for Persistent Login State and Data

- [ ] Review +/- Test

Message Signing

`

const signMessage = async () => {

    try {

      setConsole("Signing message");

      const ethersProvider = ethers.getDefaultProvider(providerUrl);

      const wallet = new ethers.Wallet(key, ethersProvider);

      const originalMessage = "YOUR_MESSAGE";

      // Sign the message

      const signedMessage = await wallet.signMessage(originalMessage);

      console.log(signedMessage)

    } catch (e) {

      console.log(e)

    }

  };

`

Transaction Sending

`

const sendTransaction = async () => {

    try {

      setConsole("Sending transaction");

      const ethersProvider = ethers.getDefaultProvider(providerUrl);

      const wallet = new ethers.Wallet(key, ethersProvider);

      const destination = "0x40e1c367Eca34250cAF1bc8330E9EddfD403fC56";

      // Convert 1 ether to wei

      const amount = ethers.utils.parseEther("0.001");

      // Submit transaction to the blockchain

      const tx = await wallet.sendTransaction({

        to: destination,

        value: amount,

        maxPriorityFeePerGas: "5000000000", // Max priority fee per gas

        maxFeePerGas: "6000000000000", // Max fee per gas

      });

      console.log(tx)

    } catch (e) {

      console.log(e)

    }
