Can customers pay in USDC without buying SOL first?

Yes, when you enable and fund Cedros Pay's optional network-fee sponsorship. SOL is the token used to pay Solana network fees; sponsorship lets your business cover those fees so a customer only needs the USDC required for the purchase in a compatible Solana wallet. Keep your fee wallet funded to offer this checkout experience. Customers who prefer cards can use your supported card checkout instead. Learn about fee sponsorship.
