一、unclaimtransaction是什么意思?

I think the answer above is good.FYI, there are several possible reasons why this payment is 'Unclaimed':1. Recipient has not yet opened a PayPal Account.2. Recipient has not confirmed their email address.3. Recipient has not registered the same email address to their PayPal account that you have sent the payment to.4. The recipient has not chosen to accept or refuse the payment.5. The recipient’s email address was entered incorrectly when payment was sent.We recommend communicating with the other party involved, as this is often the quickest way to resolve this situation.Just to note that an ‘Unclaimed’ payment will be automatically returned to you after 30 days, if it is not claimed by the recipient.
