OpenSea is happy to facilitate NFT sales that involve a legal transfer of physical goods or rights, but it is the seller’s responsibility to both:
a) ensure the legality of that transfer,
b) coordinate with the buyer (through the item unlockable content section) in order to ensure those items are delivered as expected.
Our involvement with these sales only goes so far as the transfer of the digital item. Buyers should make sure there is a way to coordinate with the seller for any off-platform transfers before committing to purchase a digital item.
