Proof of Usefulness Score
Gaining Momentum

Ottr Finance was a legitimate, self-custody Solana wallet that was acquired by Tools for Humanity (Worldcoin) in February 2024 and subsequently sunsetted. While the project demonstrated significant real-world utility and achieved a verified user base of ~25,000 monthly active users (contradicting the submission's claim of 'everyone'), the submission itself is of extremely low quality, containing exaggerated claims ('most people have used my product') and missing data. The score reflects the project's historical success and acquisition exit, heavily penalized for the poor submission quality and the fact that the product is no longer active.
