We will never contact you soliciting cryptocurrency recovery services, or offering to help you recover seized assets. We are aware of numerous fraudsters impersonating our company and our team members. Please do not engage with them and if you have lost cryptocurrency, your best course of action is to contact your local law enforcement.
