A DeFi staking platform allows users to lock up their digital assets to support a blockchain network or a decentralized application (dApp) in exchange for rewards. Staking typically involves holding tokens in a wallet to help secure the network, validate transactions, or participate in governance. These platforms offer users the ability to earn passive income through interest or rewards, while also supporting decentralized networks. Popular DeFi staking platforms include platforms like Aave, Yearn Finance, and PancakeSwap, which provide various staking opportunities.
