If you have chosen to use a Precise exchange, you will notice that there is a 5-minute timer. If the timer expires, the exchange will fail. In the case that your timer has expired but you still sent digital assets to ShapeShift, please wait for our auto-return feature to send you your return after it confirms on the blockchain. If you do not receive your auto-return, please open a support ticket.
Keep in mind that Quick exchanges do not have a timer, so if you think that you will need more than 5 minutes, opt for this exchange type.
