Udacity Blockchain Capstone

This is the Capstone Project of Udacity Blockchain Nanodegree program done by Stiff Roy.

Contract addresses

The contracts were deployed to the Rinkeby test network and the addresses of the contracts are:

SolnSquareVerifier: 0x8100A00EFc97A9bbf3EB94806986a2C76612c52C SquareVerifier: 0x057743a34D66f72CbCd6B0A4c81019b8823c7AFd

NOTE: We can focus on the SolnSquareVerifier contract

Items deployed in the marketplace

All the items are developed with ERC721 standards and minted via MyEtherWallet. Later the items were deployed to the OpenSea Marketplace and can be found with the token name of Bari.

Items buy and sell history (for testing purpose only)

All the items were owned by "StiffR1" and then 5 of them were sold to "StiffR2" through OpenSea marketplace. .

Testing

To test the smart contracts, please go to the folder eth-contracts and either run truffle test or go into the development console of truffle: truffle develop and execute test.

NOTE: make sure the npm packages are installed before running the test by executing npm install in your base directory.
