DeFi Risk & Reward Analyzer (Self-Assessment)
A framework to guide your research and subjective assessment of a DeFi opportunity.
Important: DeFi is high-risk. This tool is for educational and self-assessment purposes ONLY. Data is user-inputted, and APY/APRs change rapidly. This tool does NOT provide investment advice or endorse any platform. Scores are based on YOUR ratings. Always Do Your Own Research (DYOR) and consult a financial advisor.

// or split the canvas. For now, it will attempt to fit on one or more pages by scaling.
