I listed an item on OpenSea for 0.01 ETH. It wasn't an auction, just a fixed price. I received an offer for 0.01 WETH. I don't understand the advantage to using WETH vs ETH. Why would somebody offer 0.01 WETH instead of simply purchasing it for 0.01 ETH as I listed it?
Are they doing this to get me to pay the gas fees instead of them? Do I pay any gas fees if I accept the offer for 0.01 WETH?
