DeFi Projects and Protocols Examples

Decentralized Finance (DeFi) encompasses a wide range of innovative protocols and projects, each addressing different aspects of the financial ecosystem, such as lending, borrowing, trading, insurance, and derivatives. These DeFi protocols are primarily built on blockchain platforms like Ethereum, but increasingly other blockchain networks like Binance Smart Chain, Solana, and Avalanche are also supporting DeFi applications.

Projects and Protocols
