The UCP payment handling is correct. Latency is a bit higher than our non-UCP flows, but still within acceptable bounds for checkout.

Used this to add UCP checkout support to our app. The spec compliance is exact — everything we tested against the conformance suite passed.

Payment token exchange is solid. We process UCP transactions across multiple merchants and have not hit any protocol-level issues in three months.
