Description

Fiat-NFT payment plugin for FLOW wallets

Problem statement

• Accepting direct card payments for NFTs requires significant dev work
• Currently, FLOW wallets require you to buy crypto first, then buy the NFT, paying twice the fees and taking double the time

Target audience

• Wallets on FLOW wanting to offer direct card NFT checkouts for their users

Evidence for the need

• Direct card-to-NFT purchases boosts sales by 300% (MoonPay survey)
• Discussions with software engineers building wallets and infrastructure on FLOW

Proposed solution

• Fiat-NFT payment solution that plugs into wallets on FLOW

Impact

• Higher sales conversions for FLOW projects
• Improved Wallet user experience

In what ways does this benefit the broader Flow developer ecosystem?

• Save months of dev work
• Handle FIAT payments for wallet providers
• Handle fraudulent activities and offer chargeback guarantee
