Hi,

I’m working on Blockcerts V3. I can verify the certificate on the website [blockcerts.org](http://blockcerts.org). However, I failed to add the certificate to the Android Blockcerts Wallet. Is there any attribute I’m missing to add on the cert? Thank you.

Hi,

Yes at this moment the official release available on the stores does not support v3. The repos both have v3 support but there hasn’t been a proper window to have the release ready.

I think this will come later this year
