# Methodology Versioning ### Methodology Updates and Versions * Each rating report and fact sheet explicitly states the **methodology version** under which it was produced. * When we update the methodology (e.g., weights, questions, mapping to ratings), we: * Publish a **methodology update note** * Explain the expected impact on existing ratings * Apply the new version to each subsequent rating This ensures that ratings remain **comparable over time** while the framework evolves with the market. ### Preview vs. Full Ratings DeFi ratings come in two variants: * **Preview ratings** have a version suffixed with `-preview` (e.g. `v0.1-alpha-preview`). 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
