What are gas fees, and when it need to be paid? 

Gas is a fee that users must pay in order to complete transactions on the Ethereum blockchain. Since OpenSea is built on Ethereum, every OpenSea trade would have consumers paying gas costs. 

Therefore, the challenge is, when should you pay for gas? 

First-time vendors must pay two trading fees when registering their NFT. The initial transaction is to authorize OpenSea to place sell orders on your behalf. When a sale happens, the second trade is required so that OpenSea may acquire your NFT.  

Based on the part of a deal, sometimes the buyer may be required to pay for the gas, while in others, the sellers may be required to pay for gas. For example, when buying a fixed-price product, buyers will simply have to settle the processing fee, and sellers will have to spend on gas when accepting the bid.
