AAVE, JustLend, and Compound Finance are pretty comparable in their functionality, although there are a few differences in the features offered. Each of the protocols has its own strengths: Compound Finance supports the most assets. JustLend currently provides the highest average borrow APYs. AAVE has the most comprehensive security audits. However, AAVE is active on 8 blockchains, Compound is running on 3 blockchains, whereas JustLand is only on TRON blockchain, this gives the former two more presence, thus more users. While Ethereum remains the largest blockchain platform with the most users, AAVE and Compound certainly benefit from the Ethereum ecosystem.
