All about the Topper service
Topper is an on-ramp service provided by the crypto exchange Uphold that allows you to purchase XRP using credit or debit cards.
Topper can be found on our on-ramp launchpad here: buy-sell-xrp.xumm.app
and our on-ramp xApp at: xumm.app/detect/app:xumm.buysellxrp.
While we have partnered with Uphold to offer services to purchase XRP via the Topper xApp in Xumm, unfortunately we not do have access to their internal systems.
