These ratings rely solely on publicly available information and do not go through the full rating process including team review. Preview ratings include both a **known score** (based on publicly verifiable information) and a **potential score** (the rating that could be achieved if the protocol undergoes a full rating, including improvements suggested by the Staking Rewards team). Preview ratings do not have a risk report available for purchase on the Staking Rewards platform. * **Full ratings** go through the complete rating process including team review. They do not have a potential score. Fully rated protocols will have a risk report available to purchase on the Staking Rewards platform.
