ERC721 token for sale/purchase of property

Implementing ERC-721 using open-zeplin

Libraries used

1. node.js
2. truffle
3. openzeppeline-solidity

Getting started with truffle boxes

Follow below instructions to initialize new ethereum project from truffle boxes. We will use webpack template

mkdir BTProperty-Token`
cd BTProperty-Token
truffle unbox webpack
npm install openzeppelin-solidity@2.0.0

Versions compatibility

Update compiler version of solidity in `truffle-config.js`
Install compatible version of ethers `npm install ethers@4.0.20`

Cleanup unsed files

Delete files from contracts(except Migrations.sol) and test folders.

Create BTProperty.sol in Remix

Create Smart Contract in Remix and make sure there is no compilation errors

Running the truffle

Start the truffle console

truffle develop
compile
migrate --reset
test

Running front end application

To start the front-end on http://localhost8080 in new terminal rpm run dev

Front end application will be started. Now you can interact with your deployed Smart Contract from web application.

Integration with MetaMask

In order to perform transaction from front-end, you need to integrate your local blockchain with Metamask.

Go to your metamask plugin
Use option, Connect using “Custom RPC”, at address http://127.0.0.1:9545/
This is the port number, where the "truffle develop" runs the local network

Integration with Infura

If you want to interact with public ethereum networks e.g. (Mainnet, Testnet), you need to create Infura account
