Prime Rating

Permissionless framework for quantifying the quality and risk of open finance.

Introducing Prime Rating

Prime Rating is a permissionless and comprehensive framework for quantifying the quality and risk of open finance protocols. Prime Rating offers a simple and comparable opinion in the form of a letter rating on a scale from A+ to D representing the overall quality of an open finance protocol from a neutral view, based on publicly available data. The Prime Rating system operates through a permissionless process governed by the Prime Rating DAO. Prime Rating is built to improve the resiliency and functionality of the open finance ecosystem, educate end-users about the functionalities and associated risks, and create a benchmark for an open financial system that is permissionless, trustless transparent while respecting users' sovereignty. V.1 of Prime Rating evaluates protocols from the perspective of a protocol token holder based on smart contract quality, data quality, and fundamental quality.​

Permissionless Rating

To provide a neutral and all-encompassing opinion on open finance protocols, Prime Rating has developed a permissionless and modular framework that utilizes DAO best practices and decentralized data storage to operate as independently from any centralized entity as technologically possible. By being permissionless, Prime Rating is more resilient, neutral, and able to leverage the wisdom of the crowd. All Prime Ratings and documents are publicly available and can be accessed non-exclusively by anyone with an internet connection, making Prime Rating a public good for the benefit of the systemic advancement of open finance.
