In the sandbox environment there is a delay of approximately two minutes before the KYC status is set to PASSED. KYC verifications run using the sandbox environment are always approved. In the production environment, most KYC applications are approved within minutes. To make the KYC verification as fast as possible, it is important to include a high-quality image of the user's identification document. The document image should not be blurry; the entire document must be visible; the text must be completely legible; the image should not have any glare, and you must use an appropriate resolution. It is possible for applications to take up to 72 hours to approve depending on the details that you submit. If an application has been pending for longer than 72 hours, contact app@celsius.network for support.
