I also got Curve from Huawei working on GrapheneOS.
I don't know if it's a coincidence with the uninstallation of HMS core but this is what I did:

  1. Install Huawei App Gallery, Curve and HMS core.
  2. Try to enable Curve NFC but gets stuck in endless waiting.
  3. Uninstall HMS core.
  4. Try again to enable Curve NFC, this time it worked.
  5. Install HMS Core again .

Not need of Huawei account or special permissions.

Now I have pending to make a payment to see if it works.

mgeo Oh. Missed that post.

Isn't the whole purpose of these cards and apps to track their users?

    I read the reviews of Curve app on google store, there are quite many 1/5 or so.
    I decided I don't need this feature that much. The use case that I went for a walk with kids, forgot wallet and they want ice cream is not that important.

    Tbh, I'm long past this. Fidesmo pay works wonderfully with watches, bracelets and rings. I have a cnick ring linked with my debitcard, easy. Don't even have to take out the phone to pay, and it's outsourced from the phone as well.

    kALIMIzT I just registered to thank you and confirm this. Got it working on latest lineage os 22.1 following your guidelines. I was struggling a lot in the beginning because I missed linking the Huawei and Google accounts and just created a new one. Did everything else but it still didn't work. It was a matter of linking the accounts in manage my account inside the Huawei app gallery and it worked.

    Thanks for the guidelines!

      andonl Yes, as already mentioned 4.81.1 has the feature.

      I've been trying it and works perfectly.

      This solves NFC payments for at least European GOS users, you can pay with Curve Pay and it charges whatever other card you have from your local bank.

      Thanks Curve for not including any Play Integrity BS!!

          Sadly curve is not available in whole Europe. It is only for the EEA countries.

              I can confirm it is currently working in the UK. It unfortunately needs to be in owner profile to work by the way. My wife is happy to use it like that, I'm not so sure yet.

              However, I am extremely happy about Curve giving GrapheneOS users the option, finally, to pay with their phones if their banking app didn't already have the functionality
