Pledge Protocol (“Pledge”) is an algorithm-driven lending platform on the Binance Smart Chain. Pledge enables users to utilize their idle crypto assets by supplying liquidity to borrowers who take loans pledged by over-collateralized crypto assets. This creates a secured lending environment where lenders receive a fixed interest rate annually (APY) with earnings accumulated per block, while borrowers pay fixed and predictable interest. The difference of Pledge from other DeFi lending protocols is the ability to create various liquidity pools with different maturities for a given crypto asset featuring fixed lending terms for each loan. Selling crypto is costly, incurring capital gains tax, KYC check and other frictions, thus borrowing is better when addressing the need for portfolio diversification or instant liquidity. Yet most available lending protocols only feature floating rate loans, mainly focused on crypto traders who borrow digital assets in real-time for day trading. Instead, Pledge answers the need for longer-term financing, mainly serving crypto-asset holders to diversify their portfolio with non-crypto assets, e.g. real estate, without the friction of adjusting existing positions. Pledge utilizes the Binance Smart Chain for fast, low-cost transactions while accessing a deep network of wrapped tokens and liquidity.
