Common Questions

Why can't I change the Solution Group?

If you came from a marketplace, the Solution Group is automatically set for you. This makes sure you're using the right settings. You can't change it, and that's okay - it's supposed to be that way!

Do I need to connect my wallet?

It depends how you got here:

• Came from a marketplace? No! Your wallet is already connected. Just enter your email and submit.

• Came here directly? Yes, you need to connect your wallet. Click "Connect Wallet" and choose your wallet from the list.

Why is the Submit button grayed out?

The Submit button only works when everything is ready:

• You've chosen a Solution Group (or it's already filled in)

• You've entered your email address

• Your wallet is connected (only if you came here directly)

Make sure all the boxes are filled in correctly!

What happens after I submit?

Here's the simple version:

1. You submit your information ✅

2. You get an email with a link to verify your identity 📧

3. You click the link and take photos of your ID and yourself 📸

4. You wait for approval (usually a few hours to a few days) ⏳

That's it! The whole process usually takes a few days from start to finish.

3. Fix the problem - Maybe your photo wasn't clear, or your ID wasn't readable

4. Start over - Go back to the beginning and try again

Can I use the same email more than once?

Yes! You can use the same email address, but each time you submit, it creates a new verification process. If you need to start over, you can submit again with the same email.

Do I have to finish everything in one sitting?

Good news: No, you don't!

• The form: Try to complete this in one go

• SumSub verification: Do this when you get the email (the link might expire after a while)
