I don't know if it is sure and safe but supposedly i pay and not pay such cosmic commissions as you are now. How can i do this ?
As long as the hike Ethereum gas continues, you can not do anything to avoid it. I have seen where the gas is bigger the total assets to be sent. You can only wait for the gas fees to be reduced. Only the Ethereum Miners knows when though.
I have stopped anything that has to do with Ethereum blockchain.
