Aave is a decentralized non-custodial liquidity protocol where users can participate as depositors or borrowers. Depositors provide liquidity to the market to earn a passive income, while borrowers are able to borrow in an overcollateralized (perpetually) or undercollateralized (one-block liquidity) fashion.
Aave's borrow interest rate model is central in the management of liquidity risk. As utilization rises, so do the borrow rates as a consequence of the higher price of capital. The Interest Rate Model is described with the parameters of each currencies.
Aave Protocol has been audited and secured. The protocol is completely open source, which allows anyone to interact with a user interface client, API or directly with the smart contracts on the Ethereum network. Being open source means that you are able to build any third-party service or application to interact with the protocol and enrich your product.
AAVE is used as the centre of gravity of Aave Protocol governance. AAVE is used to vote and decide on the outcome of Aave Improvement Proposals (AIPs). Apart from this, AAVE can be staked within the protocol to provide security/insurance to the protocol/suppliers. Stakers earn staking rewards and fees from the protocol.
