As most people by now probably have heard, minting and bidding is not only expensive due to the high gas fees, it also has a very unsustainable CO2 footprint. There are already alternative NFT-scaling methods in development that include gas-free transactions, work seamlessly with the current wallet system and might even be installed as an in-place replacement for the current system.
The Rarible development team should put a priority into researching whether NFT-scaling can be integrated into the platform without jeopardizing security or breaking the current workflow.
