In the miner settings, instead of the wallet address, unlike other pools, you must specify your login and the name of the worker through the dot.

For example, your HashCity login is - username and you want to give the name to the worker rx580_rig, in the field -wallet or -username (unlike the miner) you will need to write username.rx580_rig

! Claymore must add -allcoins 1
