I thought I logged in using a QR code, but I just tried to cast via Herocast and it didn't work. I'll let @hellno confirm this. 

Is there a way to see/verify onchain how many EdDSA keypairs one has created?

herocast uses signers, just migrated to onchain signers using the new API endpoints. Did you login via QR before migration?

If you tried to @ mention someone, there was a bug in herocast, it’s now fixed. 

If you tried to use a signer from before OP deployment, I’m currently figuring out if those are supposed to work. 

Waiting on Neynar for a server error on the hub as well.
