TRuEST™ Authentication

The Realest™ empowers partners in sports, music, and film with the industry's most advanced authentication and marketplace technology.


As forgeries grow more sophisticated with deepfakes and other emerging threats, protecting the integrity of physical memorabilia has never been more critical. Traditional authentication standards carry significant risk, but The Realest™ takes a proactive approach, partnering directly with teams, artists, and studios to source items at the origin.


Our multi-layered, witness-based authentication process (TRuEST™) sets a new industry standard and comes backed by a money-back guarantee. TRuEST™ replaces old-school certificates of authenticity with immutable provenance stored on the blockchain, clearly showing population data, creation dates, and key item details. This information cannot be altered, backdated, or hacked and remains accessible at all times. Each item is uniquely fingerprinted using our patent-pending covert markings and tamper-resistant OVD holograms.


These security measures ensure The Realest™ can verify authenticity with absolute certainty, now and in the future, while detecting any attempts to alter or counterfeit items using undisclosed, cutting-edge security methods.
