CapStone Project

Objective of this project is to develope a decentralized Real-Estate listing service.The real estate properties are represented by the ERC721 tokens. We are using the zk-SNARKs toolbox from ZoKrates to establish the verification mechanism before minting each token after the verification, the tokens will be listed and ready for the exchange on the blockchain decentralized marketplace OpenSea.

Contract Addresses:

1. SquareVerifier: 0xC32921D14Ba5a0e9D56F64f87480Bd368473daf5

2. SolnSquareVerifier: 0x0Db1ba13BB611FD80D64ef369b48164087010DBA

OpenSea Storefront: https://rinkeby.opensea.io/assets/real-estate-token-v8

Contract ABI will be found here: ./eth-contracts/build/contracts/*.json

Steps--:

Installation

• git clone this repository
• npm install

Truffle Tests

• truffle test to run the tests suite

To Deploy Smart Contracts

You need to setup the truffle-config.js, with your wallet and infura account before deploy to the rinkeby network

• truffle compile to compile contracts
• truffle migrate --reset --network rinkeby to deploy to rinkeby network
