 # ERC-721 Token — Reference Implementation
 
-This is the complete reference implementation of the [ERC-721](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md) non-fungible token standard for the Ethereum blockchain. This is an open source project, complete with [Specron](https://specron.github.io/framework/) testing.

-Purpose of this implementation is to provide a good starting point for anyone who wants to use and develop non-fungible tokens on the Ethereum blockchain. Instead of re-implementing the ERC-721 yourself you can use this code which has gone through multiple audits and we hope it will be extensively used by the community in the future.

 You can quickly deploy a contract with this library using [Remix IDE](https://remix.ethereum.org). Here is one example.
 
-You have created and have possession of unique glass-blown artwork (each having a serial number / lot number) which you would like to sell using Ethereum mainnet. You will sell non-fungible tokens and the buyers would be able to trade those to other people. One token per piece of artwork. You commit to anybody holding these tokens that they may redeem there token and take physical posession of the art.

You will sell non-fungible tokens and the buyers would be able to trade those to other people. One token per piece of artwork. You commit to anybody holding these tokens that they may redeem there token and take physical posession of the art.
 
 To do this, simply paste the code belowe into Remix and deploy the smart contract. You will "mint" a token for each new piece of artwork you want to see. Then you will "burn" that token when you surrender physical possession of the piece.

 We already deployed some contracts to [Ropsten](https://ropsten.etherscan.io/) network. You can play with them RIGHT NOW. No need to install software. In this test version of the contract, anybody can `mint` or `burn` tokens, so don't use it for anything important.
