Local Smart Contract Deployment and UI Interaction

To deploy and interact on your local blockchain network, follow these steps:

1. Start a Local Hardhat Node:

   npx hardhat node

   This command starts a local Ethereum JSON-RPC server at http://127.0.0.1:8545/ Also you can see a list of test accounts you can use later

2. Deploy the Contract Locally:

   npx hardhat ignition deploy ./ignition/modules/DEDUAssess.js --network localhost

3. Add local network to MetaMask

   First, you need to visit our website. In the pop-up window, you will need to connect your MetaMask wallet.

   Next, we go to MetaMask and connect to our local network:

   • First click. Select a network

   • Second click. + Add a custome network

   

   You should see something similar to this.

4. Get test account

   When you run npx hardhat node, you may see many test account:

   

   These are test accounts that have tokens on the network and can be used for network testing. Choose one account that you like and copy its private key.

   Now you need to return to MetaMask:

   • First click: accounts
   • Second click: + Account or hardware wallet
   • Third click: Import account

   

   Now click import and test account should appear in your wallet.(with 10000 tokens)

   

   Now you can return to our website and perform system testing :)

Running UI localy

You can use deployed website on https://web-zeta-wheat-80.vercel.app/ but it is also possible to start it localy

1. clone web repository
2. npm install
3. npm run dev

Using UI

1. After connecting to metamask you can see a starting page. Firstly add a project.

2. After reloading projects, you can see the project in a "Projects you can verify" list

3. Choose different account in MetaMask and reload page

   

4. Now open the project and submit a task

5. Choose previous account and open your project. You can see a submitted task.

6. Verify or reject it and reload submission lists

7. You can verify any submission on "Verify Submission" Page
