Card adapter

Data flow

The card step spends claimed USDG on-chain before issuance. An idempotent claim ID ties the provider request to delivery, and the design returns USDG entitlement after issuance failure.

Design boundary

Card regions, limits and any verification requirements belong to the third-party program. Production availability is not implied by this preview.

How it fits

The owner chooses a card route, signs the request and follows the intended in-app delivery status.

Lifecycle

The same cumulative claimed balance prevents consuming one entitlement again through a different route.
