Why do I get an error when transferring an NFT onto ELYT?

On ELYT, NFT transfers are only possible between addresses on the system. If the recipient address to which you want to transfer NFT does not belong to an ELYT account, the transfer will fail. To send NFT to addresses other than ELYT, first mint the relevant NFT, withdraw it to your Metamask wallet, and then send it using the traditional method.
