Today’s decentalized fintech solutions fall short
Current decentralized financial services come with many limitations and can’t meet the needs of consumers who want to seamlessly transition to the rapidly evolving digital economy.
-
Inability to spend crypto assets
Consumers want to spend their digital assets, but merchants only accept fiat currency.
-
Complex, inefficient card issuing
Businesses want to issue crypto payment cards, but the process is too restrictive and often doesn’t align with their customer acquisition strategy.
-
Limited functionality
Current solutions focus mostly on payments, neglecting the broader consumer needs for “everyday” decentralized financial services.
-
Forgettable branding
Standard card designs offer no memorable way to stand out at the point of sale.
