Buying crypto with cards is no longer your only option

Purchasing crypto with a credit card can present challenges, such as low authorization rates, strict purchase limits, and high fees.

Sardine’s fraud technology allows us to take on risk that banks typically avoid, to give your customers higher, dynamic limits and instant access to their funds.
