I would like to remind you that our Node Operator Terms of Service specify that you must use the same payout address for all your nodes. If you followed this requirement, you would not be facing this high fee problem now. So I wonder why do you have STORJ on 4 different zkSync L2 addresses?
I would urge you to change your node configurations to specify the same zkSync payout address for all your nodes, so that in the future you would not have any need to spend tokens on compacting STORJ tokens into a single zkSync address.
Other community members may have some input on their experience with L2 → L2 transfer fees. You might also be interested in reading recommendations in this thread.
