Pay with Dai (DAI)

Pay any U.CASH merchant with Dai. Your DAI settles final and direct from your wallet, with low fees and no chargebacks.

Why pay with Dai

Crypto payments are final, global, and cheap. Dai is a strong way to pay merchants directly.

No chargebacks

DAI payments are final on-chain. No card-style disputes clawing funds back weeks later.

Borderless

Pay any U.CASH merchant worldwide. No blocked regions, no currency conversion holds.

Low fees

Network fees instead of card processing percentages, especially on efficient chains.

Private by default

No card number to hand over. You sign a transaction from your own wallet.

Pay by name

Send to a web3 name (ENS, Unstoppable Domains, FIO) instead of a long address.

Fast settlement

Merchants see your payment confirm quickly, then release goods or services.
