Does Peatio take care of ERC20 tx fees?


I’m not so sure about Peatio 1.9, but it seems for version 1.8 the method create_withdrawal for the class ERC20 doesn’t have any gas price or gas limit in the parameters passed to the JSON-RPC request. Is this method just as an example, to be always overwritten by each particular token? If so, how does one handle the transaction fees for each token, or are those automatically handled by Peatio? Since my understanding is that token wallets would need to have also ETH stored in it for the fees.
