Why do you pick Ether as your blockchain solution? Are you planning to stick with it or upgrade? Something with more scale and less Gas fees?
Smart contracts on Ethereum blockchain and specifically ERC-20/ERC-721 standards are currently the most reliable and well tested in our opinion. Of course, we always look out for the best experience/delivery for the users, so if the community starts to adopt a better standard, we'll certainly research it. What were you referring to when you mentioned more scale and smaller gas fees?
