Atlendis is a capital-efficient DeFi lending protocol that enables uncollateralized crypto loans. Institutional borrowers can obtain flexible and competitive loan terms. Uncollateralized loans function as a revolving line of credit, giving borrowers flexibility for recurrent and short-term liquidity needs. Lenders earn high returns on actively loaned-out capital and have granular control over their investment portfolios. Unused capital is placed on a trusted third-party liquidity protocol, while simultaneously earning additional returns from Atlendis. There is no idle capital on Atlendis, enabling trusted borrowing and lending, and opening a wide range of use cases for borrowers.
