PayPal and Curve Pay support tap-to-pay on GrapheneOS in Europe where they have it deployed. Google Pay bans using GrapheneOS for it via the Play Integrity API. Most banks only support using Google Pay rather than having an alternative in their apps. Many European banks have an alternative. PayPal's app does still work on GrapheneOS, they only accidentally broke it with the default settings due to bugs in their anti-tampering code. Disabling the per-app exploit protection compatibility mode works around it. They should fix it and start testing on GrapheneOS.
