Project: Collateralized Loan Smart Contract Development

In this project, you will develop, deploy, and interact with a simple collateralized loan contract on the Ethereum blockchain using Solidity. This contract will manage loans backed by Ethereum as collateral, offering hands-on experience with real-world financial smart contracts.

Getting Started

Use the following command to clone the repo:

git clone Getting https://github.com/udacity/cd13282-blockchain-with-solidity-project

cd cd13282-blockchain-with-solidity-project

Once you have the starter code, head over to the starter directory. You will notice one folder: hardhat-js . We have mostly been using hardhat with JavaScript.

Dependencies

We will mostly use hardhat for this project to write, deploy and test the smart contract.

Installation

Head over to hardhat-js and install the necessary dependencies with the following command.

npm install

You will also find a file .env.example , you will need to create a .env file similar to that.

INFURA_API_KEY=
ACCOUNT_PRIVATE_KEY=

Add your wallet private key and infura API key.

Testing

Head over to test folder and create a new file to write the tests.

Project Deliverables

1. Deploy the Smart Contract on Sepolia Testnet

• Successfully deploy your Collateralized Loan smart contract to the Sepolia testnet.

2. Write the Smart Contract and Hardhat Test Script

• Develop and finalize the Solidity code for the Collateralized Loan contract.
• Write comprehensive test scripts using Hardhat to validate the contract's functionalities.

3. Etherscan Verification

• Provide a link to the Sepolia Etherscan page confirming the successful deployment of your contract.
• The Etherscan link should display the contract address and transaction details on the Sepolia testnet.

4. GitHub Repository Link

• Submit the link to your GitHub repository containing the project.
• The repository should include:
  • The Solidity smart contract code.
  • Hardhat test scripts.
  • A README file containing the Sepolia Etherscan link of the deployed contract

Notes for Submission

• Ensure that the GitHub repository is public and accessible.
• Double-check the Etherscan link to ensure it directs to the correct contract and network.
• The smart contract code should be well-commented for clarity and understanding.
• Hardhat Test Scripts should cover all critical paths and edge cases in the contract functionality.
• The README must contain the Sepolia Etherscan link of the deployed contract.
