Overview

This is my first project in Solidity and Ethereum! I've learned how to deploy and run a smart contract on the Ethereum blockchain.

Land

The purpose of this smart contract is to simplify land registration and eliminate scammers. It includes various methods, and here are a few important ones:

• transferOwnership: This function transfers the ownership of the land to another Ethereum account. Only the account specified in the owner variable can execute this function.
• whoIsTheOwner: This function allows others to find out who the owner of the land is.
• changeMyDetails: This function enables the owner to modify their details. Only the owner can call this function.

Deploy with Hardhat to Infura Sepolia

Install the packages

npm i

Configure the deployment:

mv .env.example .env

and fill in the details in .env

Compile the contracts:

npx hardhat compile

Deploy the contract:

npx hardhat run --network sepolia scripts/deploy.js

Testing the Deployed Contract

To test a deployed contract by doing the steps above, You need to use Land UI - a testing place for contracts.

Land UI is made with React and Vite, so you need to cd into land_ui and start the server.

Here are the steps to do that:

cd

cd land_ui

Install Packages

npm i

Start the Server

npm run dev

YouTube Videos

If you're interested in learning Solidity and smart contracts, I found these videos helpful in gaining a better understanding of the concepts. Each video has a maximum duration of 20 minutes:
