I want to change my smart contract and make it more professional to follow ERC721 standard. [login to view URL] I would like to have the same functions on my new ERC721 smart contract: 1) Store a certificate in Ethereum, 2) transfer the certificate to a new owner. Can you please help me with the change to ERC721 standard and implement it on Ethereum? I appreciate your kind consideration. Thank you
