There are two ways to reach us.
In-app chat
Open the support chat in the app. You're already signed in, so we know which account you're asking about and you can skip the identity questions. This is the fastest option during support hours.
Write to [email protected]. Use the email address on your Lumina account if you can, since that lets us verify it's you without extra back and forth.
Hours
We're online 9:00 AM to 5:00 PM ET, Monday through Friday. If you write outside those hours, your message will be waiting for us in the morning. You don't need to send it twice.
What to include
Specifics help us fix things on the first reply:
the market or transaction you're asking about, with the date and amount
what you expected to happen, and what happened instead
a screenshot, if the problem is visible on screen
If it's urgent
If you suspect someone else has been in your account, secure it before you write to us. The steps are in Keeping your account secure.
