Changelly always cares about security. We are against fraudulent and malicious activities in the crypto world. Even though, Changelly is positioned as a cryptocurrency exchange that doesn’t require revealing identities, we may demand additional information from you for KYC procedures, if we find your transaction suspicious. In this case, you must provide us with a photo of your face with the ID document (passport or driving license) valid in your country and a piece of paper with the date and the inscription "Changelly" on it in one photo for the KYC procedure and information on the origin of the funds as well. These documents must be sent to security@changelly.com
