Hi i now read everywhere that a transaction fee has to be paid in ETH.
But I also found via the ethereum page the following page:
where it says
Sets the currency that the fee is paid in
The latter two methods are optional; also, note that the fee may be charged either in ether or subcurrency;
So is it finally possible to create an ERC20 Token that is able to transfer its tokes and is paid in the token itself? If so, is there an example contract somewhere or do I just have to add it into the constructor? If so what exactly has to be the _feeCurrency variable? The AdminAddress of the contract?
