Psyche allows each receiver to accept or reject an incoming transaction and users can simply reject a payment if they don’t want to receive or they are not agreed on the incoming amount. I think it is something unusual but interesting decision

won't that hamper a troublesome system and transactions take a long time? if they do it like that, is it done manually? and what is the purpose for such a product to be created?
An interesting idea but a little awkward when you think about it logically
