I am trying to create my own ERC-721 non fungible token and unable to find any docs, basic code and how to deploy it on a testnet. Could someone share the official specification and an example of how to implement an ERC-721 token?
The most official documentation for this token is the request by itself on GitHub.
The author of
Non-fungible Token Standard is Dieter Shirley. He was first to implement it on 20 Sep 2017.
I am also looking to see if I have basic code, how to deploy it on a testnet.
There are too many good answers on this particular question and there are also multiple ways to do it, I will just leave few links.
