Why does an invoice expire after 20 minutes?
It is done to protect our merchants and their customers from crypto price volatility as we fix the price when invoice is generated. That is how we guarantee that the seller gets the right amount for his merchandise, and a customer will not encounter any problems when paying if the price fluctuates.
Regardless, our merchants have the possibility to extend the invoice expiration time up to 24 hours. You can do that by clicking the “Edit” button on the existing merchant tool.
