Android supports multiple payment providers. Some banks implement their own payment provider (e.g. Sparkasse in Germany), most just rely on Google Pay (now Google Wallet). Google Wallet has strict requirements for the Play Integrity API. Because of the modifications to Android that GrapheneOS is implementing, it is not eligible to receive the required integrity attestation and thus, Google Wallet is refusing to work. Google could at any point reconsider and certify/whitlelist GrapheneOS, which would allow Google Wallet to work using GrapheneOS. Likelihood close to 0.
Any banking app implementing their own payment provider is completely independent of this decision unless it also relies on Play Integrity API attestation (or a similar mechanism).
out of curiosity, are you aware what changes exactly make the Play Integrity API eligibility requirements not able to be met? with Google play installed, the compatibility layer should be able to facilitate the necessary communication, I would think.
or are they just arbitrarily saying anything that’s not stock isn’t eligible?
