I was doing good progress being able to create and manage multiple addresses and retrieving the balance until two days ago that I started to try to do a the most basic payment transaction. I don't know how to keep forward, I think my problem is about being able to unlock the account, deploy a contract to get the contract address, but I don't find any way to do it in Unity. Is it even possible? Do I have to create the contract address by other means and then be able to use it for the payment transfer? Thanks for the support.
