About Lendr.fi
Vision and Impact:
At Lendr.fi, we envision a world where every person has equal access to financial opportunities empowering them to build wealth and prosperity for themselves. We aim to accelerate this vision by making every asset class globally accessible through Web3. To achieve this goal, we are building the world's first liquid staked real world asset token protocol. Our protocol creates real world asset (RWA) index tokens for any asset class, including real estate, AI & robotics, healthcare, energy, commodities, and more. These tokens are compliant in multiple jurisdictions globally, and compatible with all existing DeFi protocols, allowing us to beat the returns of anything currently available in Web2 or Web3. Lendr.fi is MakerDAO + Lido for RWAs. The RWA tokenization market is projected to reach $16 trillion by 2030, compared to the current $3.5 trillion valuation of all crypto. We intend to capture a significant portion of this growth.
