I created a private network with 3 instances (one controller, 2 nodes) based on PoA on AWS. And I checked if my custom ERC721token is deployable by using Ropspan test network. so I have a working-private network and a deployable smart contract.
But How can I deploy that contract on my private network? Also, I have this question. Is it possible to deploy ERC721 smart contract for free?
Please help me.
