Many U.CASH network transactions are verified by blockchain -- that's how we ensure that the digital currency you're sending is yours to send. It's one of the ways we prevent fraud in the system. It can take up to 20 minutes (usually less) from the time digital currency gets transferred to the time this transaction is verified. Exceptionally, it may take up to an hour or more for your transaction to be confirmed, depending on amount and network conditions. Until the network gets the verification that the transaction is a valid and unique one, you won't be able to send or withdraw the funds in your account.
