Mo knows security, and Mo knows that it starts at the contract level. Yes, you may be minting on Opensea, but the smart contract is not your standard OS deployment. Mo takes advantage of the SeaDrop protocol by extending their ERC721A smart contract and inheriting the ERC721X + Guardian contract developed by OwlOfMoistness at CyberKongz. So holders can designate a Guardian address (like a cold wallet) to keep their assets locked and safe from within a hot wallet.
