How many time have you heard, the transaction went to the wrong address and boom... it lost. Recently with 1M USDT, thanks to the organization which traced it out but it does not happen normally.
To accept a transaction, one must have a 6 digit approval code which sender can share with the receiver. What it prevents? Never lose the funds again while sending to a wrong address.
Psyche is not focusing on staying in exchanges only, the intention behind the whole concept is where businesses and people can use it everyday and to accomplish that, trust is very important.
Psyche proposes a coin to be used everyday, this would be the main purpose behind the Psyche blockchain.
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
