## Cost of Capital in DeFi

The Cost of Capital in DeFi refers to the effective interest rate or return requirement that a protocol or project must satisfy to attract and retain liquidity providers and lenders. Unlike traditional finance, where this is influenced by central bank rates and corporate credit ratings, the DeFi cost of capital is driven by algorithmic incentives, governance token emissions, and the perceived risk of the underlying protocol.

It represents the opportunity cost for liquidity providers who could otherwise deploy their assets into other competing protocols or centralized exchanges. This cost is dynamic and fluctuates based on the supply and demand for capital within specific liquidity pools.

Understanding this cost is essential for developers designing sustainable tokenomics and for investors seeking to optimize their yield strategies. It effectively dictates the barrier to entry for borrowing and the sustainability of lending protocols.

It is the core mechanism of decentralized capital allocation.
