A DeFi staking platform allows users to lock up their cryptocurrency holdings to support a blockchain network’s security and consensus mechanism in exchange for rewards. Staking platforms like Aave and Yearn Finance provide decentralized options where users can earn interest on their staked assets. These platforms use smart contracts to manage staking activities and ensure transparency. Users contribute to the network’s decentralization and validation processes by participating in staking while generating passive income through staking rewards.
