How to run this project

Dillinger requires Node.js v4+ to run.

download the project and install it's dependencies.

$ git clone https://github.com/Jahin0X01/Capstone_Real_Estate_Marketplace.git
$ cd Capstone_Real_Estate_Marketplace
$ npm install 

Befor you compile again remove the build directory in the eth-contracts Compile and test

$ cd eth-contracts
$ truffle compile
$ truffle test .\test\TestERC721Mintable.js  
$ truffle test .\test\TestSolnSquareVerifier.js
$ truffle test .\test\TestSquareVerifier.js  

deploy to the rinkeby network

truffle migrate --network rinkeby

you will have the contract address SolnSquareVerifier as an output of the last step and all the output i have i save in the file "rinkeby migration info".

The follwing is the SolnSquareVerifier and Verifier Deploying info and thir ABI in the Both fils named "SolnSquareVerifier-ABI" and "Verifier-ABI"

 Deploying 'SolnSquareVerifier'

if you need to know any additional info see the file "rinkeby migration info"

and you can check it in the etherscan and this is my address transactions in the rinkeby network https://rinkeby.etherscan.io/address/0x08d94E7b0Bd79A1050265C4fb9e98736d672F827 After the migration is finished we now will mint the tokens using myetherwallet https://www.myetherwallet.com/interface/interact-with-contract all you need is the contract address we have in migration step and the ABI and you can find in the eth-contracts\build\contracts\SolnSquareVerifier.json
now after creating the tokens go to https://rinkeby.opensea.io/ then go to develop section and generate your marketplace after that add an existing contract and add your contract address and you will have your items like that https://rinkeby.opensea.io/assets/jahinhouse-v2

Al the follwing is the assets I creat

First the assets that I have and sell them to the Highest offer
