Contracts

Contracts are located in the src/contracts folder

• Property.sol

The ABIs for the contracts are located in src/abis folder

Setup

• Install node.js
• Run npm install from project root to install packages
• Create a .env file in project root like the following and put your contract addresses

PROPERTY_CONTRACT_ADDRESS=<here>
REGISTRY_CONTRACT_ADDRESS=<here>

• Install metamask, setup account
• Set network on metamask to 'Rinkeby Test Network' (if you deployed smart contracts to rinkeby). Might need to enable test networks in settings.
• Run npm start to run server and visit http://locahost:3000/
• Should get prompted by metamask to connect to the website. Accept it and you're good to go!
