Aave (AAVE) is one of the emerging decentralised finance (DeFi) cryptocurrencies that runs on the Ethereum blockchain. Since its launch in 2017, during which $16.2 million was raised in an Initial Coin Offering (ICO), Aave has continued to gain popularity among crypto communities. Put simply, Aave is a lending system that allows users to lend, borrow and earn interest on their crypto assets – all without a middleman. Popularity has increased for Aave as of recent, because it allows users to take out loans in a range of different cryptocurrencies.
