I dont use the tradional OpenSea Eth minting, I use the Polygon blockchain. Which is on Eth but works differently. There is talks of 30 gwei fees now due to spam attacks, something that could happen with Wax, but they have a different whitelisting and not a verify blue tick system like OpenSea. Im not sure if this fee will be charged on creation or selling. Either way, IF I actually make enough art to tokenize, I'll be minting on various platforms.
