US Dollar on U.CASH

The US dollar is the settlement currency of world trade and the deepest fiat rail set on U.CASH: ACH, domestic wire, and the U.S. payment apps all clear in dollars, and every card processor supports it.

Rails settle it at checkout; pegged tokens settle it on-chain. Both live on the same non-custodial U.CASH checkout.

US Dollar: FAQ

Can I accept US dollar payments without a processor account?
Yes. The ACH, wire, and payment-app rails need only your bank coordinates or app handle; buyers send the dollars direct and you match the payment reference.
Which stablecoin should a USD checkout settle to?
USDT and USDC are the deepest pairs on the swap; PYUSD, FDUSD, USDP, RLUSD, USyC, and USDQ are issuer-backed alternatives. All of them track the dollar 1:1.
