We batch our users' Bitcoin transactions every 15 minutes before broadcasting them to the network to be confirmed. As long as there is no network congestion, the transactions are normally confirmed and available in the recipient wallet within the next couple of blocks.
All in all, we aim to have your transaction broadcast, confirmed and available in the recipients wallet within the hour. This may not always be possible depending on the amount of unconfirmed transactions on the network, you can read more about that here.
