The quickest way to reach TokenGem is to reply to your receipt: it comes from a monitored address, never a no-reply, and a person answers. Lost keys go to the resend page, device moves to the device page, refunds to a one-line reply, and anything else to the address below.

Reply to your receipt. The address it comes from is monitored by a person. The public support address is published on this page before the first sale is taken.
If you find a vulnerability in TokenGem, in the issuer service, or on this site, write to the support address with "security" in the subject. Please give us a reasonable time to fix it before publishing. There is no bug bounty, and you will be credited in the changelog if you want to be.
The operating entity and its address are published here, on the terms page and on every receipt before the first sale.
