The DeFi (Decentralized Finance) Index includes cryptocurrencies and blockchain projects that are focused on building decentralized financial systems, eliminating the need for traditional banking intermediaries. Examples of projects in this index include Uniswap (UNI), a decentralized exchange platform, and Aave (AAVE), a decentralized lending and borrowing protocol. DeFi platforms enable peer-to-peer transactions, lending, borrowing, and trading, all without a central authority. By tracking the DeFi Index, investors gain exposure to the growing decentralized financial ecosystem, which aims to make financial services more accessible, transparent, and efficient.
