@biboran/z please, pay attention to this issue

[rockfridrich]

We will need to discuss this issue. We can implement all tools required for sending such transaction but separate ERC20Token domain from the main library.

@rockfridrich is ERC20Token just a concrete type of a Contract with a predictable behavior?
