The little blue and gold dots next to your contacts
Sometimes you might see little coloured dots next to a contact's display picture.
They might be blue, or gold, and sometimes there might even be both.
The blue dots
This just means that your contact is a "verified user".
Put simply, this allows Lydia to certify the user's identity and entitles them to higher transaction limits.
The gold dots
This means that the user has subscribed to Lydia Premium. They have unrestricted access to all of Lydia's features.
Contacts that display both dots are therefore verified Lydia Premium users.
