A DeFi investment platform is a decentralized financial service that allows users to invest, earn interest, and trade cryptocurrencies or digital assets. These platforms operate without intermediaries, using smart contracts to automate transactions and ensure transparency. DeFi investment platforms offer various investment options, such as yield farming, staking, lending, and liquidity provision, enabling users to earn returns on their holdings. By removing traditional financial institutions, these platforms provide more accessible, borderless, and efficient investment opportunities, often with lower fees and higher potential returns.
