If you are an existing Tempo client for online and would like to use Lobstr, StellarX, or Papayabot to deposit EURT or withdrawl EURT you need to contact support to validate your account.

Email support@tempo.eu.com your stellar public key from the email account you have registered with tempo.

Ask Tempo support to setup your account for use with StellarX or Lobstr. 

They will add your stellar public key to your account information.

Thank you
