When I visit NBATopshot, you have a option to buy each pack through both creditcard and crypto (using coinbase). Is similar fiat on-ramping solution to be provided as part of SDK, or each dapp has to have their own fiat payment solution such as Stripe?
Just reached out to some internal team members who have more info on this. We will try to share more info soon.
Dapps which integrate with the Flow Client Library (FCL) will have access to all wallets that support Flow (and are also integrated with FCL) and we’re working closely with those partners to get them set-up with fiat on-ramps. So, it should be straight forward for Dapps to access fiat on-ramps through the SDK.
That’s great to know. What happens when chargeback happens?
It’ll depend largely on the service provider but will keep you posted as we know more 
@laynelafrance what would be the requirement for the recipient of the fund if I create some sort of marketplace?
When Gitcoin did CLR funding to donate for local businesses, they asked each business to setup Stripe API key.

Is something similar required for FCL?
